Description

Protective pads using damping components

technical field

The present invention relates to, but is not limited to, protective pads using damping components.

Background technique

Protective pads are traditionally used to limit the impact force suffered by people or objects. Some examples of protective pads rely on a foam-like material that is placed between the surface to be protected and the point of impact. Conventional foams have limitations with regard to repeated cleaning (such as high temperature washing), bulkiness, and manufacturing limitations.

After briefly describing an overview of embodiments of the present invention, a more detailed description follows.

Protective pads are conceived to provide protection to one or more parts of the body or object. For example, it is contemplated that a protective pad embodying one or more aspects provided herein may be used to provide protection and/or force dampening for various body parts. Examples include, but are not limited to, shin guards, knee pads, hip pads, abdominal pads, chest pads, shoulder pads, arm pads, elbow pads, and implementations in head protection such as helmets ). Furthermore, it is conceivable that this concept is applied to inanimate objects (eg columns, walls, vehicles). Thus, it is contemplated that the aspects provided herein may be useful in a variety of situations and in a variety of locations.

The protective pads provided herein are articles for reducing the effects of impact forces on the relevant part of the wearer. For example, a shin guard utilizing the features discussed herein may reduce the perception of imparted energy on the user's calf area through the use of a protective pad. This change in perception can be achieved in a number of ways. For example, energy applied at the point of impact can be distributed over a larger surface area, such as through a rigid impact shell. Additionally, it is contemplated that the dissipative/absorbent material may provide a compressive function for absorbing and/or dissipating a portion of the impact force. Conventionally, foam materials have been used to provide such absorbent functions. However, foam-based materials can have several disadvantages, such as poor response to washing (e.g., tendency to damage or otherwise lose protective qualities with repeated washing), resistance to moisture and air transfer from interior surfaces to The inability of the outer surface and the weight issue.

Accordingly, aspects of the present invention contemplate providing at least some of the advantages of protective pads (eg, energy distribution and energy absorption) while reducing some of the disadvantages associated with conventional protective pads.

FIG. 1 illustrates an exemplary protective pad 100 in accordance with aspects of the present invention. For example, protective pad 100 is depicted as a shin guard in an worn position on a wearer's leg. In this example, the shin guard 100 has a top edge 110, a bottom edge 112, a lateral edge 108, and a medial edge (not visible as depicted). The protective pad 100 curves from the medial edge to the lateral edge 108 to form a curved outer (and inner) surface around the shin region of the wearer's leg.

The protective pad illustrated in FIG. 1 also includes a first strap 114 and a second strap 116 . As will be discussed in more detail with reference to FIG. 18, the strap may be formed as part of the damping member. Additionally, it is contemplated that a strap may extend from a first side (eg, inner side) and be coupled on an opposite side (eg, outer side). Coupling of the strap may occur with a portion of the damping component and/or the impact shell 101 .

While protective pad 100 in FIG. 1 is depicted as being secured to a wearer's leg using a plurality of straps, it is contemplated that alternative securing mechanisms may be implemented. For example, protective pads may be secured via pockets, temporary adhesives, sleeved items, and the like in other items of clothing that are permanently/temporarily attached to one or more other items (e.g., pants, socks, shirts, and belts). be held in place. As will be discussed below, the ability of the protective pad 100 to move (e.g., slide, migrate, compress, deform) slightly with impact forces may provide advantages achieved through the aspects discussed herein; Mechanisms may allow this type of movement.

FIG. 2 depicts an inside perspective view of a protective pad 100 in accordance with aspects of the present invention. In particular, impact shell 101 is depicted. Impact shell 101 provides at least a distribution function to protective pad 100 (among other functions). For example, impact shell 101 is contemplated to be formed from a rigid material such as a polymer (e.g., polypropylene, woven polypropylene, polyethylene, polystyrene, polyester, polycarbonate, polyamide, and the like), carbon fiber, Metals (eg, aluminum, titanium), natural materials (eg, bamboo), and others. It is also contemplated that a variety of materials may be used in the formation of impact shell 101 . For example, a stack of sheets of material may form a shock shell with a variety of properties. Additionally, it is contemplated that various regions of the shin guard may be formed from different materials (eg, a denser type/portion of material along the centerline than along the peripheral regions). Additionally, it is contemplated that a plurality of separate parts may be combined to form the impact shell. Each of the separate parts may be formed from a similar or different material or materials.

Impact shell 101 is depicted in this example as having a curved exterior surface 102 that curves from an inboard edge 106 to an outboard edge. In an exemplary aspect, the inner surface (not shown) is curved approximately parallel to the outer surface 102 (outer surface). However, it is contemplated that the inner and outer surfaces 102 may not be parallel (eg, have a common radius) based on the varying thickness of the impact shell 101 along the length of the curved portion. Additionally, in the exemplary aspect, a consistent curved profile is not achieved over the length extending between the medial edge 106 and the lateral edge when in the worn position based on the organ shape of the underlying body part. Thus, as discussed herein, the flexural properties of the impact shell (and the damping member to be discussed below) are not limited to a continuous constant bend, but rather to a generally curved shape implemented to protect the underlying portion of the wearer. look.

FIG. 3 depicts a front perspective view of a protective pad 100 in accordance with aspects of the present invention. Protective pad 100 is depicted as having a forward-facing exterior surface 102 of impact shell 101 . As previously discussed, impact shell 101 has a perimeter at least partially bounded by top edge 110 , outboard edge 108 , bottom edge 112 , and inboard edge 106 . As used herein, the words "inboard" and "outer" are relative words intended only to express the concept of a first side edge and a second side edge. This term is used to realize the mirror image that can be used for a protective pad intended for use on the left part of the body (eg, the left leg) and a protective pad intended for use on the right part of the body (eg, the right leg).

Although not depicted, it is contemplated that the impact shell (and/or other portions of the protective pad) may be formed from two or more parts. For example, it is conceivable that the first part forms the outer part of the impact shell and the second part forms the inner part of the impact shell. The two parts may be flexibly coupled using one or more materials and/or mechanisms. In an exemplary aspect, it is contemplated that the underlying dampening member may form at least part of a coupling mechanism to maintain the first and second portions in a desired relative orientation. Additionally, it is contemplated that the first portion may be formed from a first material and the second portion may be formed from a second material. For example, locations on the protective pad that require greater reliability against impact forces may be formed from a first material that is more reliable but denser than a second material that forms a second portion at locations that are less prone to impact. It is contemplated that materials, size, and location may be adjusted to achieve benefits such as durability, weight reduction, breathability, and the like.

FIG. 4 depicts a rear perspective view of protective pad 100 in accordance with aspects of the present invention. In this example, a damping member 201 is illustrated. The damping member 201 comprises a plurality of connecting members 202 forming a network of interconnected members which in combination form a frame-like structure. For example, a mesh-like geometric pattern can be formed by connecting structural members. Various geometries of the coupling members are discussed in more detail below in connection with FIGS. 7-10.

Exemplary dampening member 201 provides a dampening effect to impact forces experienced by impact housing 101 . For example, dampening component 201 may absorb and/or dissipate some of the impact energy before it is transmitted to the wearer's protective pad 100 . This damping, dissipating and/or absorbing effect can be achieved by a variety of properties. For example, it is contemplated that an elastomeric material forms the damping member 201 in the exemplary aspect. Elastomeric materials may include thermoplastic elastomers, thermoset elastomers, rubber, synthetic rubber, and other materials that exhibit low Young's modulus and high yield strain. Examples of elastomeric materials include, but are not limited to, GLS 311-147 thermoplastic elastomer available from PolyOne Corporation of Avon Lake, Ohio. Exemplary elastomers may exhibit a tensile strength (at yield, 23°C) in the range of 0.8-8.7 MPa, a Shore hardness (A) of 16-56, and an elongation at break (at 23°C) up to 1200% (e.g., about 1000%, 800%). However, while exemplary ranges are provided, it is contemplated that additional materials exhibiting properties greater or less than one or more of the properties provided in one or more of the ranges provided may additionally/ can optionally be used. Additionally, alternative materials are contemplated.

In addition to dissipating, damping, and/or absorbing impact energy through material selection, the geometry of the connecting member can also help reduce perceived impact forces. As will be discussed below in connection with FIGS. 7-10, the thickness, length, size of the void, and geometry of the void can all affect the level of perceived impact energy. For example, longer linking members forming a sash structure may result in a "looser" sash that is more flexible and less resistant to deformation. Similarly, diamond-shaped voids between joint members may be more prone to deformation in a skewed direction than triangular-shaped voids. Skewing of the sash may be more effective at absorbing off-axis impact forces (eg, tangential impacts to the impact housing). Furthermore, the thicker the link members forming the damping sash, the more resistant the damping member may be to deformation (and thus provide less damping properties as perceived by the wearer). Additionally, as will be discussed, the offset of the extension member, the cross-sectional shape of the extension member, and the size/shape of the extension member void can all affect the perceived level of impact force.

Damping component 201 of FIG. 4 depicts an outer surface 204 formed from a plurality of interconnected joint members 202 . The joining members 202 may be formed in a common manufacturing process, such as injection molding, such that the joining members as a whole form the grid network of the damping member 201 . Joint member 202 defines a plurality of voids, such as void 216 . The void 216 extends through the outer surface 204 and the inner surface 206 of the joining member (not shown). For example, when two or more joining members form a two-dimensional shape (the two-dimensional shape may be organic in nature and/or rectilinear in nature), the internal void not occupied by a part of one of the members is Exemplary void.

The extension member 208 may be positioned (but not in all aspects) at the intersection of two or more connecting members, as will be discussed in more detail below in connection with FIG. 5 . Additionally, an extension member void 214 associated with one or more extension members may extend through the extension member and joint member outer surface 204 . Like extension members, extension member voids will be discussed in more detail below.

In the exemplary aspect, the outer surface 204 forms a user contacting surface. For example, the outer surface 204 may contact the user (eg, be positioned adjacent to the user's body) when in the worn position. However, it is contemplated that one or more additional items (e.g., socks, pant legs, sleeves, liners, absorbent materials, adhesives, sticky materials, and the like) may be placed on the outer surface 204 and the like when in the use position. between the wearer's body. Thus, the term "user contact surface" is a general description of an orientation direction when in use, but is not limited to requiring direct user contact.

As depicted in FIG. 4 , damping member 201 may generally conform to the geometry of the interior surface of impact shell 101 . For example, if the interior surface of impact shell 101 has a curved profile, damping member 201 exhibits a similar curved profile when coupled to the interior surface. However, it is contemplated that one or more geometric properties of the damping member 201 may introduce different profiles (e.g., varying offsets by extension members, varying joint member thicknesses, gaps between the damping member and interior surfaces). connection point), as will be discussed in Figure 14 below.

The extension member 208 may extend outward from the inner surface (206 in FIG. 6 ) of the damping member 201 toward the inner surface (104 in FIG. 6 ) of the impact shell 101 . The extension member void may extend through at least a portion of the extension member. For example, extension member void 214 is a spatial cavity that passes through the outer surface of damping member 201 over the offset length of the extension member and out from the distal end of the extension member. However, it is contemplated that the extension member void may extend only a portion of the extension member and/or coupling member. Additionally, it is contemplated that extension member voids may not be present in one or more extension members. As with the extension member, it is contemplated that the extension member void may have any shape, size and/or orientation. For example, it is contemplated that an extension member void may have a similar cross-sectional shape as an associated extension member. Additionally, it is contemplated that an extension member void may have a different cross-sectional shape than an associated extension member. Examples of cross-sectional shapes include, but are not limited to, circular, oval, rectangular, organic in nature, star, triangle, or any other shape.

The extension member void may provide enhanced impact attenuation characteristics through the introduction of the crumple zone functionality. For example, the inclusion of the void space provides an area where a portion of the damping member 201 (the extension member and/or the connection member) can deform to absorb impact force. Additionally, it is contemplated that the inclusion of extension member voids may provide mass reduction options, increasing the suitability and desirability of the resulting protective pad. Additionally, it is contemplated that the extension member void may provide a channel through which bonding agent may be introduced into the impact housing to maintain the impact housing and damping member in a coupled condition.

FIG. 4 also depicts four exemplary attachment points 118 , 120 , 122 , and 124 . The coupling points may include locations where the damping member is coupled to the impact housing. For example, it is contemplated that the points of attachment may represent points of bonding, ultrasonic welds, mechanical fasteners, press-fit joints, protrusions extending through the strike shell, and the like. While four exemplary attachment points are depicted, it is contemplated that any number and/or location of attachment points may be used. In addition, it is contemplated that the point of attachment may alternatively be an attachment area spanning a variety of shapes, sizes, and orientations (eg, rectilinear, peripheral, shape contoured, and the like).

In an exemplary aspect, the damping component may be coupled to the impact shell at one or more coupling points (or regions) through an overmolding process. For example, it is contemplated that a material other than the impact shell (eg, TPE) could be overmolded to the impact shell in the region where the damping component is coupled. For example, it is contemplated that the inner surface of the impact shell may be overmolded with TPE film (or any material suitable for coupling with the damping member). A damping member, which may be formed from TPE material, may then be ultrasonically welded to the TPE membrane of the impact shell. The TPE film may provide a material to which the damping component may be coupled when the underlying impact shell material is less capable.

5 depicts a perspective view of a sash-formed damping member in accordance with aspects of the present invention. The inner surface 206 is exposed along with a number of exemplary extension members 208 , extension member voids 214 , and voids 216 between the joint members 202 . The concept of offset 210 is also shown. Offset 210 is the length of the extension member extending from inner surface 206 . The offset distance may create a compressible gap between the connecting member of the damping grid and the impact shell. While extension member 208 is depicted as having a cylindrical shape, it is contemplated that any shape may be implemented. For example, a cone shape with a base extending from a sash or in the form of a plate, a cone shape with a distal end formed by the base, a pyramid shape (with a base at any location), spherical, prismatic , cube, any-numbered-ahedron shape, and similar shapes. Additionally, it is contemplated that an organized format may be implemented. Combinations of shapes/forms can be used in any combination.

6 depicts a side view of a portion of an exemplary protective pad in accordance with aspects of the present invention. Shock housing 101 is depicted forming the lower portion of FIG. 6 . In an exemplary aspect, inner surface 104 is coupled with distal end 212 of an extension member, such as extension member 208 , at least at one or more locations. As previously discussed, it is contemplated that the portion of the damping member 201 that is capable of contacting the impact housing may not be coupled with the impact housing. For example, it is contemplated that the damping member may be placed under tension (eg, stretched) on the curved inner surface of the impact shell such that the inner surface bends away from the damping member 201 . In this example, when the impact force causes sufficient force to overcome the elastic characteristics of the damping member, the distal end of the extension member 208 may contact the inner surface of the shock housing, which in turn applies additional tension that allows the damping member to at least partially stretches and conforms to the shape of the impact shell. Additionally, it is contemplated that portions of the damping member other than the distal end are coupled with the impact housing (eg, peripheral elements, extension member protrusions).

Extension member 208 is depicted extending from inner surface 104 of impact shell 101 to inner surface 206 formed by joint members 202 of damping component 201 . Also depicted is an extension member void 214 that extends through the entire thickness of the damping component 201 . In addition, it is conceivable that the void can also extend through the impact shell so that a ventilation channel is formed. A void (not depicted) extending through impact housing 101 may correspond to an extension member void and/or it may not correspond (e.g., be out of alignment) with an extension member void, but rather provide mass from exterior surface 102 to interior surface 104 Reduced and/or breathable options.

Offset 210 is depicted as being consistent across the illustrated extension members. However, it is contemplated that the offset distance may vary with a particular extension member, as will be discussed below in connection with FIG. 14 .

While the thickness between the outer surface 102 and the inner surface 104 is depicted as being constant for the impact shell 101 , it is contemplated that the thickness may vary. Additionally, while a continuous material is depicted as forming the impact shell 101, it is contemplated that multiple materials may also be used. Similarly, the thickness extending between the outer surface 204 and the inner surface 206 of the damping member 201 is depicted as remaining constant. However, it is contemplated that the thickness may vary with location. Additionally, extension member 208 is depicted as having generally parallel profiled sides; however, it is contemplated that any relative orientation may be used (eg, a tapered profile that allows for increased resistance to compression with distance of deflection).

As will be discussed in additional detail below in FIGS. depicted in Figure 28 below). Skin 602 has an outer surface 604 and an inner surface 606 . In an exemplary wearing aspect, outer surface 604 is skin-contacting (eg, contacting the wearer).

The skin 602 may be a thin layer or film applied to the outer surface 204 to provide a more attractive contact surface for the wearer when in the worn position. For example, it is contemplated that the skin may be formed from a thermoplastic elastomer (TPE). Examples of general types of TPE include styrenic block copolymers, polyolefin blends, elastomeric alloys (TEP-v or TPV), thermoplastic polyurethanes, thermoplastic copolyesters, and thermoplastic polyamides. Additionally, it is contemplated that the skin may be formed from a flocking process or from alternative laminates, appliqués, and materials.

7-13 depict exemplary structures of extension members, extension member voids, and connection members for a damper component in accordance with aspects of the present invention. In particular, FIG. 7 depicts the structure of a diamond-shaped connecting member 202 (connecting member) having a co-sized extension member 208 and an extension member void 214 at each intersection of the connecting members in accordance with aspects of the present invention. The void 216 formed is a rectangular void having four major edges bounded by the joining member 202 .

FIG. 8 depicts a damping lattice structure including four similarly sized connecting members 912, 914, 916, and 918 in accordance with an exemplary aspect of the invention. Additionally, similarly sized/shaped extension members 902, 904, 906, and 908 are located at the intersections of similarly sized connecting members. The damping sash also includes two additional connection members 920 and 922 extending from extension members 908 and 904 . The connection members 920 and 922 are joined at positions recognizable by the extension member 910 . Due to the above structure, a triangular void 924 is formed between the connection members 912 , 914 , 920 and 922 . Due to the inherent geometry of triangles, triangular voids may provide greater resistance to deformation in the lateral direction (eg, tangential impact to the protective pad) compared to rectangular shapes.

While two connecting members 920 and 922 are illustrated, it is contemplated that a single connecting member may span the distance between extension members 904 and 908 . Similarly, it is contemplated that the extension member may be located anywhere along the one or more connecting members. Additionally, while the connecting members are discussed as discrete elements, it is contemplated that the connecting members of the damping sash are continuously formed elements without discrete parts.

9 depicts a damping lattice structure including various sizes of extension members and extension member voids in accordance with aspects of the present invention. For example, it is contemplated that the damping sash includes a first extension member 1002 , a second extension member 1004 , and a third extension member 1006 . The first extension member 1002 and the second extension member 1004 share a common cylindrical shape, but different diameters. The first extension member 1002 has a larger diameter than the second extension member 1004 . In an exemplary embodiment, based on the larger diameter, the first extension member may provide greater resistance to compression; thus, it is suitable for locations on the protective pad where such properties are desired (e.g., edges, near bony structures , near soft tissue structures, near the expected point of impact). Conversely, the second extension member 1004 may be desired in a location where a large degree of relative impact absorption is desired. Both the first extension member 1002 and the second extension member 1004 have similarly sized extension member voids 1008 and 1010 . Additionally, it is contemplated that the extension member void depth may also be varied without affecting the size of the cross-section.

The third extension member 1006 is similar in size to the first extension member 1002 . However, extension member void 1012 of third extension member 1006 is larger in size relative to extension member voids 1008 and 1010 . A larger extension member void may provide greater spatial capacity for deformation of the extension member, which may result in a greater degree of impact force absorption.

It should be understood that the sizes, shapes and combinations of elements (ie, connection members, extension members and extension member voids) may be in any order, manner and/or relationship. Thus, while specific examples have been shown, it is contemplated that any combination of these elements may be used with each other to form one or more portions of the damping member.

10 depicts a damping sash structure including a plurality of connection members 1110 , 1112 , 1116 , and 1118 and a plurality of extension members 1102 , 1104 , 1106 , and 1108 that combine to form a void 1120 in accordance with aspects of the present invention. In this exemplary configuration, connecting members 1118 and 1116 have similar lengths that are longer than connecting members 1110 and 1112 . Thus, voids 1120 are diamond shaped.

Fig. 11 depicts a damping lattice structure including curved connection/joint members in accordance with an exemplary aspect of the invention. In particular, FIG. 11 depicts two connecting members 1122 and 1124 extending from extension member 208 to terminate at another extension member, which creates void 1126 . The void 1126 is at least partially bounded by the curved connecting member. While connecting member 1122 is depicted as having a mirror-image curvature to connecting member 1124, it is contemplated that any shape (eg, rectilinear, organic, or any combination) may be used. Additionally, as will be discussed below in connection with FIG. 13, it is contemplated that a combination of both linear and organ-shaped connecting members may be used. As with the other void shapes and connecting member shapes discussed herein, it is contemplated that any size, orientation, and final shape can be used in any combination at any location in order to achieve a desired damping result (e.g., impact force attenuation). implement.

12 depicts a damping lattice structure including organ-shaped connecting members in accordance with an exemplary aspect of the invention. FIG. 12 includes a plurality of connection members of different shapes and sizes, such as connection members 1202 , 1204 and 1206 . While straight-line connecting members may be used to extend from a first extension member to a second extension member, it is contemplated that organ-shaped connecting members, such as connecting member 1202, include one or more bends, bows, or can be positioned in a purely straight line. Other variations in shape extend the length of the connecting member. The addition of the organoid form may provide additional damping properties by allowing additional movement in the damping sash upon impact.

Although not explicitly depicted in the figures, it is contemplated that the extension member may represent an increase in the thickness of the connecting member relative to the thickness at different locations along the connecting member. For example, it is contemplated that along the connection member 1204 the depth increases at a portion such as in the middle of the upwardly curved central portion to effectively create an offset, as previously discussed with respect to offset 210 of FIG. 6 . In other words, the change in thickness of the connecting member allows at least a portion of the inner surface of the connecting member to be offset from the inner (ie, proximate) surface of the impact shell.

FIG. 13 depicts a damping lattice structure including organ-shaped and rectilinear connecting members in accordance with an exemplary aspect of the invention. In particular, Figure 13 shows that different connecting member lengths and shapes can be used in combination. For example, connecting member 1302 is rectilinear in shape, but extends with a similar final length as connecting member 1304, which is more organic in shape. Similarly, it is contemplated that additional connection members 1306 may extend a greater distance from common extension member 208 . Additionally, it is contemplated that any width, thickness, length, shape, cross-sectional shape, material, color, and combination thereof may be implemented in the exemplary aspects of the damping sash.

14 depicts a view from the top edge toward the bottom edge of a protective pad portion in accordance with aspects of the present invention. The protective pad includes a shock shell 101 and a damping member 201 . In this example, impact shell 101 is curved outwardly towards exterior surface 102 . The curvature of the shock housing may be defined by a radius 1206 extending from an imaginary point 1212 on axis 1201 .

The damping member 201 may be formed such that it includes extension members giving different offset distances. For example, first offset 1402 may be greater than second offset 1404 . Depending on the shape of the shock shell, this change in offset may be introduced to provide a consistently curved outer surface 204 of the damping member (eg, to compensate for an irregularly curved shock shell). Alternatively, the change in offset distance may be used to introduce an irregular curved profile on the outer surface 204 of the damping member 201 to better shape the wearer's anatomy. Additionally, it is contemplated that the offset distance may be varied at key locations (eg, along soft tissue contact areas, along bone areas) to achieve desired impact attenuation characteristics.

Additionally, as depicted in FIG. 14 , it is contemplated that offset centers (eg, 1212 and 1210 ) may be used as opposed to impact shell 101 and damping member 201 sharing a common center of curvature. In an exemplary aspect, the offset center is comparable to the offset length (eg, 1402) of the extension member. In another exemplary aspect, the radius 1208 of the damping member 201 may vary with position. For example, the radius may increase as it is rotated by a larger deflection angle from axis 1201 . In this example, offset 1402 may be greater than offset 1404 when radius 1206 changes by a small amount, if at all, for comparable deflection angles.

Thus, changes in connection members, extension members, extension member voids, voids, offsets, curved profiles, materials, and the like can all contribute to various contemplated aspects of the protective pad including the impact shell and damping components. Although the protective pad construction is described above with reference to particular embodiments, it should be understood that modifications and changes may be made to the described protective pad construction without departing from the intended scope of protection provided by the following claims.

15 depicts exemplary protrusions on a damping component for mating with exemplary channels in an impact shell for coupling parts in accordance with aspects of the present invention. As previously discussed, damping member 201 may be coupled to impact housing 101 by a variety of different mechanisms and means. For example, as depicted in FIG. 15, it is contemplated that one or more channels may be formed in impact shell 101 that function to receive one or more channels extending from the damping member. a protrusion. The channel may extend along a peripheral portion of the impact housing 101, along an interior portion of the impact housing 101, or any other portion of the impact housing, such as the inner surface of the impact housing. Length, shape (both cross-sectional and along the surface of the impingement shell), size and position may vary and are contemplated to include a range of options. For example, it is contemplated that a first channel having a first shape may extend along a first portion of the impact shell and a second channel of a different size, shape, and/or length may extend along or through the impact shell The second part of the extension.

Examples of different channels are depicted in FIG. 15 . For example, rectangular cross-sectional channels 1504, "T"-shaped cross-sectional channels 1508, barbed cross-sectional channels 1512, and flared "T"-shaped cross-sectional channels 1516 are provided. It is contemplated that additional forms may be implemented in the exemplary aspects.

Examples of different protrusions are depicted extending from the damping member. For example, a rectangular cross-sectional protrusion 1502, a "T" shaped protrusion 1506, a barbed protrusion 1510, and a rounded protrusion 1514 are provided.

Different combinations of protrusions and channels can provide different functional advantages. For example, rectangular protrusion 1502 and rectangular channel 1504 may be adapted to prevent lateral movement between the damping member and the impact housing while still allowing for a separation aspect. The "T" shaped protrusion 1506 and "T" shaped channel 1508 can provide high resistance to separation by forces that are not parallel to the channel. However, this arrangement may still allow the damping member to be separated from the impact housing by a sliding action that guides the protrusion through the channel. The domed protrusion 1514 may be adapted to expand/compress to fill a portion of a receiving channel, such as the barbed cross-sectional channel 1512 or the "T" shaped cross-sectional channel 1516 . In this example, the dome-shaped protrusion is compressible in sections to expand into the barbed extension of the receiving channel 1512 . Similarly, when the dome-shaped protrusion 1514 is compressed into the receiving channel form 1516, the dome-shaped protrusion 1514 may eventually assume a "T" shape. This compressive fit may provide resistance to separation between the damping member and the impact shell.

While the discussion has focused on protrusions extending from the damping member and channels formed in the impact housing, it is contemplated that one or more protrusions may extend from the impact housing and one or more channels may be formed in the damping housing. formed in the part. Additionally, it is conceivable that the protrusions are integrally formed with the base material (eg damping member material) from which they extend. Furthermore, it is conceivable that the protrusions are formed from different materials or during different process flows.

16 depicts an exemplary protrusion on a damping component for serving as a coupling member through one or more receiving chambers in an impact shell in accordance with aspects of the present invention. Receiving chambers 1606 and 1610 are cavities within the receiving material that allow retention of received protrusions 1608 and/or 1612, as opposed to channels that run the length, which may be likened to a rivet-like connection in some examples. For example, receiving chamber 1606 may allow insertion integration of protrusion 1608 as protrusion 1608 extends from damping member 201 through impact shell 101 . To maintain the coupled relationship, the protrusion 1608 is formed with a stem 1602 having a cross-section that is smaller than the head of the protrusion. In this example, the head is rounded to provide easier insertion through the receiving chamber insertion hole, which is then occupied by the rod 1602 . While a recessed head is depicted, it is contemplated that the recessed head may not be implemented in the exemplary aspect.

Protrusion 1612 depicts a different cross-sectional shape at the head portion than protrusion 1608 . The rod portion 1604 extends to the recessed portion of the receiving chamber 1610 through the receiving chamber insertion hole. While the recessed portion is depicted as extending to the outer surface, it is contemplated that the receiving chamber could instead be a void within the impact shell that does not extend all the way to the outer surface, which would then provide a uniform outer surface for the impact shell Appearance.

As previously discussed with respect to FIG. 15 , it is contemplated that, in exemplary aspects, the protrusion and receiving chamber may be formed in either damping member 201 or impact housing 101 .

17 depicts a cross-sectional view of a damping member coupled with an impact shell along its perimeter using a shim-like fit in accordance with aspects of the present invention. The cross-sectional views of the damping member 201 and the impact shell 101 represent at least two different mechanisms for using a shim-shaped coupling. The washer-shaped coupling includes the extension of a portion of the damping member 201 from the inner surface of the impact shell 101 to the outer surface 102 . This may be accomplished by lip portion 1712 extending along a portion (such as the perimeter) of the damping member to extend around a portion (such as the edge perimeter) of the shock shell. The damping member 201 may form a receiving channel 1714 in which the perimeter edge of the impact shell is retained. In this example, the inner surface of the impingement shell may be proximate to the inner surface of the damping member, and the outer surface 102 of the impingement shell may be proximate to the lip portion 1712 along the perimeter portion. Thus, in this exemplary aspect, the lip surrounds a portion of the strike shell to form a coupling bond between the damping member and the strike shell.

In an additional exemplary aspect, it is contemplated that raised portion 1704 may extend through strike housing 101 and engage lip 1708 . For example, it is contemplated that the distal portion of the raised portion may be bonded (eg, welded, stapled, chemically fixed) to the inner portion 1706 of the lip 1708 . It is also contemplated that protrusion 1704 may extend through lip portion 1708 and form a mechanical fastener. Additionally, it is contemplated that protrusion 1704 is temporarily or permanently coupled to the shock housing, where protrusion 1704 extends through the shock housing.

It is contemplated that protrusion 1704 may be located at any location relative to the shock housing (or damping member). For example, it is contemplated that protrusion 1704 (and any number of similar protrusions) may be positioned along the perimeter to pass through receiving channel 1714 at any location. Furthermore, it is envisioned that the protrusions, which may be of any shape, size, length, material (similar to and/or different from the damping member), be located at any location.

18 depicts an exemplary protective pad with integrated straps of damping components in accordance with aspects of the present invention. The exterior surface 102 of the impact shell 101 is depicted with a first band 1802 and a second band 1804 extending from the outer side 108 . In an exemplary aspect, first strap 1802 and second strap 1804 may extend to opposite sides (eg, inside) of the protective pad, as depicted by lines of action 1810 and 1820 . Each of the straps may then be secured to the protective pad to maintain the protective pad in a worn position on the user.

The first strap includes closure tabs 1806 . Closure tab 1806 is depicted as a portion of band 1802 that extends beyond a surface, such as an inner surface. The impact housing may have a receiving cavity 1808 for receiving the closure protrusion. Similar concepts discussed in connection with FIGS. 15 and 16 for the shape, size, and the like of projections, channels, and chambers may apply to receiving cavity 1808 and/or closure projection 1806 . It is contemplated that the closure tab may fit within the receiving cavity to maintain the strap 1802 in a desired coupled (eg, detachable) condition.

Similarly, a second band 1804 is shown with an alternative arrangement of a first closure protrusion 1812 and a second closure protrusion 1814 . Corresponding receiving holes 1816 and 1818 are formed on opposite sides of the protective pad (eg, in the impact shell, damping member, and/or combination) for receiving closure projections. It is contemplated that any combination of closure projections and receiving cavities may be used in any combination. Additionally, it is contemplated that other components (eg, hook and loop material, snaps, buttons, clips, ties, and the like) may additionally or alternatively be used to couple the strap to the protective pad.

Returning to straps 1802 and 1804, it is contemplated that the straps are formed as part of the damping member. For example, in a common forming (eg, molding) operation, each of the bands is formed from the same material as that used to form the damping member. Additionally, it is contemplated that the straps may be used as connecting members extending from edge portions of the protective pad. Additionally, while the inner and outer sides are drawn out for purposes of explaining FIG. 18, it is contemplated that the bands may originate from or terminate at any portion of the protective pad. Additionally, while the ribbons are depicted in a rectilinear shape, it should be understood that any shape, size, and orientation can be implemented.

Additionally, it is contemplated that instead of having a protrusion extending from the damping member, the protrusion may alternatively or additionally extend from the impact shell (inner or outer surface). Additionally, it is contemplated that strapping of the strap may be accomplished through a series of receiving cavities or protrusions extending along the strap and/or a portion of the impact shell. For example, it is envisioned that a series of receiving cavities extend along the outer surface of the impact shell in a pattern that can be matched by two or more protrusions extending along the length of the strap.

Figure 19 depicts a perspective view of a damping component formed with a sheet form 1901 in accordance with aspects of the present invention. The inner surface 1906 of the sheet form 1901 is exposed along with a number of exemplary extension members 1908 and extension member voids 1914 . The concept of offset 1910 is also shown. Offset 1910 is the length of the extension member extending from inner surface 1906 .

In this example, outer surface 1904 is opposite inner surface 1906 . The thickness of the material extending between the inner surface 1906 and the outer surface 1904 may vary with location to achieve varying physical properties such as elasticity, impact force attenuation, and the like. In this example, sheet-like form 1901 may not include a void extending between inner surface 1906 and outer surface 1904 . However, it is contemplated that one or more extension member voids 1914 may extend from the distal end of one or more of the extension members 1908 through the extension member and through the sheet form 1901 . In this example, an extension member void extending through outer surface 1904 may form a hole at outer surface 1904 . The holes may be effective to facilitate the flow of air and/or moisture. Additionally, it is conceivable that the aperture may be effective to facilitate a better contact surface between the user and the damping member.

20 depicts a front perspective view of an additional exemplary embodiment of an impact shell for a protective pad in accordance with aspects of the present invention. Impact housing 2000 is depicted as having forward-facing exterior surface 102 . Impact shell 2000 also has a perimeter at least partially bounded by top edge 110 , outer edge 108 , bottom edge 112 , and inner edge 106 . Additionally, the impact shell 2000 includes a plurality of perforations or cutouts along the perimeter of the impact shell 2000 . The perforations can be of uniform shape and size around the entire perimeter, or can be of varying shapes and sizes (as shown). For example, the perforations may be circular perforations 2002, triangular perforations 2006, rectangular perforations 2004, or any other suitable or desired shape may be used. The perforations may be consistent in size throughout, or different sized perforations may be used for different regions around the perimeter of impact shell 2000 . Additionally, the perforations may be evenly spaced around the perimeter of the impact shell 2000 (as shown) or may be spaced at different length intervals. As contemplated herein, the perforations extend through the impact shell from the exterior surface to the interior surface. As will be discussed below, it is contemplated that the perforations provide an area through which overmolded material may pass during the molding process to form the attached coupling frame.

FIG. 21 depicts the exterior surface of an exemplary impact housing. For example, impact shell 2100 shown in FIG. 21 is an exemplary embodiment of impact shell 2000 . Impact shell 2100 is depicted as having a plurality of perforations 2110 along top edge 110 and bottom edge 112 , perforations 2130 along outer edge 108 and inner edge 106 , and finally perforations 2120 corresponding to the four corners of impact shell 2100 . A plurality of perforations provided in impact shell 2100 are shown having a generally rectangular shape. Additionally, multiple circular perforations near the bottom edge are depicted. An exemplary circular perforation is 2902. As previously discussed, it is contemplated that the perforations may be of any size, shape and be in any location. Furthermore, it is contemplated that any combination of size, shape and position may be utilized in various aspects of the invention.

In this exemplary aspect, perforation 2110 is depicted as having top edge 2112 , bottom edge 2116 , outer edge 2114 , and inner edge 2118 . A plurality of perforations 2110 , 2120 , 2130 are provided along and near the perimeter of the impact shell 2100 . In an exemplary aspect, the plurality of perforations may be provided closer to top edge 110 , outer edge 108 , bottom edge 112 , and/or inner edge 106 than the center of impact shell 2100 . For example, considering a perforation 2110 near a rigid housing top edge 110 , the top edge 2112 of the perforation 2110 may be at least from 1 mm to 1 cm away from the corresponding rigid housing top edge 110 . Furthermore, in an exemplary aspect, the top edge 2112 can be at least from 1 mm to 1 cm from the bottom edge 2116 and the lateral edge 2114 can be at least from 5 mm to 5 cm from the medial edge 2118 . It is contemplated that similar lengths may apply to other alternative perforated edges (eg, circular perforated circumferential edges).

The plurality of perforations in this exemplary embodiment of impact housing 2100 serve as locking channels for allowing the coupling frame to surround the entire perimeter of impact housing 2100 (or in another exemplary aspect, around impact housing 2100 part of the perimeter) is formed and locked in place. The coupling frame around the perimeter of impact shell 2100 may be formed by various suitable methods, including injection molding or any other suitable technique. In this way, a coupling frame can be formed on both sides of the impact shell 2100 by filling the plurality of perforations 2110, 2120, and 2130 with a coupling frame material and interconnecting the filled perforated materials. A coupling frame is formed to effectively lock the coupling frame to the impact shell. For example, as will be discussed below with reference to FIG. 22 , impact shell 2100 is shown in FIG. 22 as impact shell 2200 having coupling frame 2210 formed around its perimeter.

22 depicts an impact shell with an integrated coupling frame in accordance with aspects of the present invention. The coupling frame 2210 may include the same elastomer material (not shown) as the damping member. In an optional aspect, the coupling frame may be formed from a material that is compatible with the damping component, so that the damping component and coupling frame 2210 can be attached to each other. In accordance with aspects of the present invention, coupling/attachment may employ thermal or ultrasonic fusion, thermal or ultrasonic activated adhesive layers, epoxies, glue, mechanical fasteners and the damping member and coupling frame 2210 may be attached together other connection mechanisms to achieve.

Coupling frame 2210 may be formed around the perimeter of strike shell 2100 to form strike shell 2200, for example, by placing the strike shell in a mold and filling the desired areas with the elastomeric material of choice. Material is then allowed to flow through and fill each of the plurality of perforations 2110, 2120, 2130 and or 2902 in FIG. 21 such that a layer can be formed around the perimeter on the exterior surface 102 and/or interior surface (not shown). This filling of the perforations may form an effective locking mechanism for the coupling frame to the impact housing by incorporating the coupling frame through the impact housing perforations. In other words, the material forming the joint frame extends through the perforations and around the perimeter from the top surface to the bottom surface to form an integral joint frame, as depicted in cross-sectional views 24, 25 and 29 below.

Furthermore, while dimensional features are depicted near certain perforations (e.g., near cut lines 23-23), it is also contemplated that the coupling frame may be substantially planar on one or more surfaces ( For example, no dimension features). In exemplary aspects, this planar aspect can provide a uniform coupling surface and/or a uniform appearance. Cut line 29-29 defines a cross-section having a substantially planar surface, depicted in FIG. 29 below, near circular perforation 2902 in FIG. 21 .

23 depicts a cross-section 2300 along cut line 23-23 of FIG. 22 in accordance with aspects of the present invention. The cross-section 2300 has the top edge of the strike shell 2200 shown in FIG. 22 , where the structure of the coupling frame 2210 is shown in more detail in FIG. 22 . For example, once coupling frame 2210 is molded or otherwise formed around the perimeter of strike shell 2100 , coupling frame 2210 has inner face structure 2310 , outer face structure 2330 , and top surface 2320 . As seen in FIG. 23, the elastomeric material comprising coupling frame 2210 flows through perforations 2110, and depending on the particular mold used in forming the coupling frame depicted in this example, coupling frame 2210 may be formed to have a height 2350 and a width 2360. The inner face structure 2310, the width 2360 is wider than the width of the perforation 2110. Additionally, coupling frame 2210 may form exterior face structure 2330 having height 2370 and width 2390 . The overall thickness 2395 of the coupling frame 2210 may be measured at any point within the perforation 2110 or at the top surface 2320 .
