Description

The present invention relates to a seat, and in particular to a trim structure that is fixed to a cushion pad.

Seats such as automobile seats have a seat cushion that supports the buttocks of the seated person and a seat back that supports the back of the seated person, and these have a structure in which a cushion pad made of a resin material or the like is covered with a trim made of leather, vinyl leather, or the like. The trim is fixed to the cushion pad on the back side of the cushion pad (the side opposite the side that comes into contact with the buttocks or back).

Patent document 1 discloses a structure in which the edge of the trim is fixed to a seat frame that is integrally molded with the cushion pad on the back surface of the cushion pad using an ohm clip.

Patent document 2 also discloses a structure in which a fastener with an arrowhead-shaped tip and to which the edge of the trim is fixed is pushed into a hole provided in the cushion pad on the back surface of the cushion pad, thereby fixing the trim to the cushion pad.

Japanese Patent Application Publication No. 09-276091 Patent No. 6107460

However, with the structures disclosed in Patent Documents 1 and 2, it is difficult to secure the trim to the cushion pad with high workability. Specifically, with the structure disclosed in Patent Document 1, it is necessary to use a hook ringer when attaching the ohm clip to the seat frame, but the hook ringer is heavy and does not allow for good workability.

In addition, in the structure disclosed in Patent Document 2, when the arrowhead-shaped portion is inserted into the hole, the fastener is provided with an extension that extends along the periphery of the hole in the cushion pad to prevent wrinkles in the trim, and when fixing the trim to the cushion pad, the worker holds the side end of the extension with his or her fingers while working. For this reason, when a worker repeatedly performs the above-mentioned tasks, hand fatigue accumulates, which may reduce workability.

The present invention seeks to solve the above problems, and aims to provide a seat with a structure that allows the trim to be fixed to the cushion pad with high workability.

A seat according to one aspect of the present invention comprises a cushion pad having a support area that supports a seated occupant and another area excluding the support area and having a hole in the thickness direction; a trim having a covering area that covers the support area of the cushion pad and an edge portion arranged in the vicinity of the hole; and a clip having a trim fixing portion to which the edge portion of the trim is fixed and an insertion portion to be inserted into the hole, wherein the trim fixing portion has a flat shape and is arranged to follow the outer surface of the cushion pad around the hole when the insertion portion is inserted into the hole, and the edge portion of the trim has an enveloping portion that can envelop a portion of an end of the trim fixing portion, and the edge portion of the trim is fixed to the opposite side of the trim fixing portion to the cushion pad in the thickness direction, and has an openable and closable window portion formed by a C-shaped slit at or near the end of the trim fixing portion, and the window portion is the enveloping portion.

In the seat according to the above aspect, the trim can be fixed to the cushion pad by the simple operation of pushing the insertion portion of the clip, whose edge portion has already been fixed, into a hole provided in the cushion pad, so there is no need to use a heavy hook ring when fixing the trim to the cushion pad, as in the technology disclosed in Patent Document 1 above.

In addition, in the seat according to the above embodiment, the worker can support a part of the end of the trim fixing part that is wrapped in the wrapping part, and in this state, insert the insertion part of the clip into the hole. In other words, the wrapping part is inserted between the end of the clip and the worker's fingers and functions as a cushioning material, so that even when the worker performs the work repeatedly, the accumulation of hand fatigue as in the technology disclosed in the above Patent Document 2 is prevented, and a decrease in workability is suppressed.

In addition, in the seat according to the above embodiment, a configuration is adopted in which the trim has a window portion as an enveloping portion, so that the worker can insert a finger into the window portion and press the end of the trim fixing portion with the inserted finger to insert the insertion portion of the clip into the hole. By supporting the end of the trim fixing portion with the finger inserted through the window portion in this way, it is possible to directly support the trim fixing portion with the window portion, which is part of the trim, sandwiched therebetween, and even when the worker performs the work repeatedly, accumulation of hand fatigue as in the technique disclosed in the above Patent Document 2 is prevented, and a decrease in workability is suppressed.
Therefore, in the seat according to the above aspect, high workability can be achieved when fixing the trim to the cushion pad.

In the seat according to the above aspect, both the trim fixing portion and the insert portion have a rectangular shape in a plan view, and the trim fixing portion has one end portion spaced apart from the hole portion when the insert portion is inserted into the hole portion, and the other end portion is continuous with the insert portion on the hole portion side, and the end portion of the trim fixing portion is the one end portion, and at least two of the window portions of the trim are provided along the one end portion of the trim fixing portion and spaced apart from each other.

As described above, by providing at least two windows spaced apart from each other, the worker can support the clip with two fingers, reducing the force exerted on one finger. This makes it possible to more reliably prevent hand fatigue from building up even when the worker performs the task repeatedly, and is even more advantageous in preventing a decline in workability.

In the seat according to the above aspect, the cushion pad may have a recess in the thickness direction of the cushion pad at the one end of the trim fixing portion and in the area nearby.

As described above, by providing a recess in the cushion pad at the one end of the trim fixing portion and the portion in the vicinity thereof, an operator can insert a finger through the window into the recess to separate the trim fixing portion of the clip from the outer surface of the cushion pad. By separating the trim fixing portion from the outer surface of the cushion pad in this manner, the insertion portion that continues at the other end of the trim fixing portion can be tilted to separate it from the side wall surface of the hole, making it possible to easily remove the clip from the cushion pad. This is therefore advantageous in ensuring high workability when attempting to remove the trim from the cushion pad when, for example, replacing the trim.

In the seat according to the above aspect, when the trim fixing portion is viewed in plan, the trim fixing portion has a side end portion connecting the ends of the one end portion and the other end portion, the edge portion of the trim extends outward from the trim fixing portion beyond the side end portion of the trim fixing portion, and has a side end covering portion capable of enveloping the side end portion, and the window portion and the side end covering portion are the enveloping portion.

As described above, by providing a side end covering portion that covers the side end of the trim fixing portion as an enveloping portion, the worker can grasp the side end of the trim fixing portion by sandwiching the side end covering portion between them. In this case, too, the side end covering portion of the trim functions as a buffer between the worker's fingers and the side end of the trim fixing portion, so that even when the worker performs the work repeatedly, the accumulation of hand fatigue can be suppressed, and a decrease in workability is suppressed.

When a worker attempts to fasten the trim to the cushion pad, the worker may support only the end of the trim fastening part, may grasp only the side end of the trim fastening part, or may place his/her fingers on both parts while working. In other words, by providing the side end covering part on the trim as described above, the worker can choose to support and grasp either the window part or the side end covering part, whichever is easier for the worker to work with. This also reduces the worker's fatigue, and is advantageous in preventing a decrease in workability.

In the seat according to the above aspect, the trim may be formed so as to extend outwardly of the trim fixing portion beyond the one end of the trim fixing portion and continue into the covering area.

As described above, when a configuration is adopted in which the trim extends beyond the one end of the trim fixing part and outward from the trim fixing part, and the extended portion continues into the covered area, tension can be applied to the trim by an operator grasping one end or side end of the trim fixing part and moving the clip to the part where the hole is provided. This is advantageous in ensuring high workability while making it difficult for wrinkles to form in the covered area.

In the seat according to the above aspect, the trim may be fixed to the trim fixing portion at a portion that extends linearly along the one end of the trim fixing portion.

As described above, if the fixing points of the trim in the trim fixing portion extend linearly in the above direction, unevenness in the degree of tension of the trim is unlikely to occur. Specifically, in the structure disclosed in the above Patent Document 1, the trim is fixed to the seat frame using Ohm clips. The trim is fixed to the seat frame at points that are spaced apart from each other. Therefore, in the structure disclosed in the above Patent Document 1, unevenness in the degree of tension of the trim occurs, which is likely to cause wrinkles.

In contrast, if the trim fixing portion is made to extend linearly as described above, the degree of tension on the trim is less likely to be uneven, and wrinkles are suppressed.

In the seats according to the above aspects, the trim can be fixed to the cushion pad with high workability.

FIG.

The following describes an embodiment of the present invention with reference to the drawings. Note that the embodiment described below is merely an example of the present invention, and the present invention is not limited to the embodiment described below except for its essential configuration.

[First embodiment]
1. General Configuration of Seat 1 The seat 1 according to this embodiment is a vehicle seat such as an automobile, and a rear seat is used as an example.

The general configuration of the seat 1 will be described with reference to Figures 1 to 3. Note that in each of the figures attached to this specification, only the seat cushion 10 of the seat 1 is shown, and the seat back is not shown.

As shown in FIG. 1, the seat cushion 10 of the seat 1 includes a cushion pad 11 and a trim 12. The cushion pad 11 supports the buttocks of a seated occupant with its front surface 11a. In other words, the front surface 11a of the cushion pad 11 corresponds to the "support area" and the other areas correspond to the "other areas."

As shown in FIG. 3, the cushion pad 11 is formed by laminating a relatively hard pad 111 and a relatively soft pad 112. The soft pad 112 is laminated on the front surface 11a and front surface 11b of the cushion pad 11 so as to cover the hard pad 111. The hard pad 111 is exposed to the outside on the back surface 11c side of the cushion pad 11.

The hard pad 111 is relatively hard compared to the soft pad 112, and the soft pad 112 is relatively soft compared to the hard pad 111. Specifically, the hard pad 111 is made of bead foam and has shape retention, while the soft pad 112 is made of urethane foam and has elasticity.

Returning to FIG. 1, the trim 12 is provided so as to cover at least the front surface 11a and the front surface 11b of the cushion pad 11. In this embodiment, the area of the trim 12 that covers the front surface 11a and the front surface 11b corresponds to the "covered area." The trim 12 is made of a sheet-like material such as leather or vinyl leather.

As shown in FIG. 2, when the cushion pad 11 is viewed in plan from the back surface 11c side, the hard pad 111 is exposed to the outside except for the edge portion. A plurality of grooves 11d are provided along the outer edge of the hard pad 111. Each of the plurality of grooves 11d has an elongated opening.

As shown in FIG. 3, each groove 11d has a recess 11h in the middle of the depth direction (Z direction) where the side wall surface 11g of the groove 11d is recessed outward in the cross-sectional direction.

Returning to FIG. 2, a flexible groove 11e is provided along each groove 11d and spaced apart from each groove 11d. Note that the groove 11d corresponds to a "hole."

As shown in FIG. 3, the flexibility groove 11e is formed to have approximately the same groove depth as the groove 11d. Note that the area between the groove 11d and the flexibility groove 11e in the hard pad 111 bends in the X direction when an external force is applied.

Returning to FIG. 2, in the region between groove 11d and flexibility groove 11e, recesses 11f are provided on both longitudinal sides of the openings of groove 11d and flexibility groove 11e.

As shown in FIG. 3, the depth of the recess 11f is shallower than the depth of the groove 11d and the flexibility groove 11e.

2. Fixing the Trim 12 to the Cushion Pad 11 The manner in which the trim 12 is fixed to the cushion pad 11 will be described with reference to FIG.

As shown in FIG. 4, the edge 12a of the trim 12 is positioned on the back surface 11c of the cushion pad 11. The edge 12a of the trim 12 is fixed to the clip 13. A portion of the clip 13 is inserted into a groove 11d provided in the hard pad 111.

The end of the portion of the clip 13 to which the trim 12 is fixed is located on the recess 11f provided in the hard pad 111.

The detailed structure of the clip 13 will be described later.

3. Structure of Clip 13 The structure of the clip 13 will be described with reference to FIG.

As shown in FIG. 5, the clip 13 has an elongated shape with a Y-direction dimension L13 that is longer than the X-direction and Z-direction dimensions. The Y-direction dimension of the clip 13 is, for example, 50 mm to 150 mm. As shown in FIG. 5, the clip 13 is formed by integrally forming a trim fixing portion 13a, a base portion 13b, a pressing portion 13c, and a return portion 13f. The clip 13 is formed, for example, from polypropylene. The base portion 13b and the pressing portion 13c of the clip 13 correspond to the "insertion portion."

When viewed from the Z direction, the trim fixing portion 13a is a flat plate having a rectangular shape with four sides defined by the ends 13i, 13j and the side ends 13g, 13h. The trim fixing portion 13a is connected to the base portion 13b at the end 13j, and the end 13i is a free end. The end 13i corresponds to the "one end" and the end 13j corresponds to the "other end".

The pressing portion 13c is continuous with the base portion 13b at the bottom end 13d of the base portion 13b (the end that becomes the groove bottom 11j side when the base portion 13d is inserted into the groove portion 11d as shown in FIG. 4), and the end (tip) 13e on the trim fixing portion 13a side (upper side in the Z direction in FIG. 5) is a free end. The pressing portion 13c is formed in a curved shape that moves away from the base portion 13b from the bottom end 13d of the base portion 13b toward the middle part in the Z direction, and approaches the base portion 13b from the middle part toward the tip 13e.

The thickness of the trim fixing portion 13a and the base portion 13b is 1 to 4 mm (for example, 2 mm). In contrast, the maximum thickness of the pressing portion 13c is set to be thinner than the thickness of the base portion 13b, for example, 1.2 mm. By making the thickness of the pressing portion 13c thinner than the thickness of the base portion 13b in this way, when the base portion 13b and the pressing portion 13c are inserted into the groove portion 11d, the pressing portion 13c can be reliably deflected as shown by the arrow (see FIG. 5) by the reaction force from the side wall surface 11g of the groove portion 11d (see FIG. 3).

The return portion 13f protrudes from near the bottom end 13d of the base portion 13b toward the opposite side of the pressing portion 13c in the thickness direction (X direction) of the base portion 13b (the right side in the X direction in FIG. 5), and has a pointed tip. The upper surface of the return portion 13f in the Z direction is formed as a flat surface that is approximately parallel to the trim fixing portion 13a. The amount of protrusion of the return portion 13f is, for example, 1.5 mm.

4. Structure of Edge Portion 12a of Trim 12 The structure of edge portion 12a of trim 12 will be described with reference to FIGS.

As shown in Figures 6 and 7, the edge portion 12a of the trim 12 is fixed to the trim fixing portion 13a. More specifically, as shown in Figure 7, the edge portion 12a of the trim 12 is folded back at the folded back portion 12b and fixed to the trim fixing portion 13a at the fixing portion 12c that is closer to the end than the folded back portion 12b. The folded back portion 12b is located midway between the end portions 13i and 13j in the X direction.

As shown in FIG. 6, the edge portion 12a of the trim 12 has a width in the Y direction that is set to be approximately the same as the width of the trim fixing portion 13a. The fixing portion 12c of the trim 12 is formed to extend linearly in the Y direction. In other words, the trim 12 is fixed to the trim fixing portion 13a in a line rather than at a point. This makes it less likely that unevenness will occur in the degree to which the trim 12 is pulled, and suppresses the occurrence of wrinkles.

Two windows 12d are provided on the edge 12a of the trim 12. Each window 12d is formed by a C-shaped slit that starts and ends at or near the end 13i of the trim fixing portion 13a, and can be opened by the worker inserting his or her finger. The window 12d corresponds to the "envelopment portion."

As shown in FIG. 7, the window 12d is provided with a size that allows a worker who is fixing the trim 12 to the cushion pad 11 to insert his or her finger through. The two windows 12d are provided spaced apart from each other in the Y direction.

5. Method of Attaching the Trim 12 to the Cushion Pad 11 The method of attaching the trim 12 to the cushion pad 11 will be described with reference to FIG.

As shown in FIG. 8, when attaching the trim 12 to the cushion pad 11, first, each fixing portion 12c of the trim 12 is sewn to the trim fixing portion 13a of the clip 13. As shown in FIG. 8, the trim 12 extends to the left in the X direction from the portion where the window portion 12d is provided, and continues to the covering region that covers the front surface 11a and front surface 11b of the cushion pad 11.

The worker attaching the trim 12 to the cushion pad 11 inserts a finger of the worker's hand 500 (thumb 500a in FIG. 8) into the window 12d to support the end 13i of the trim fixing part 13a. The other finger of the worker's hand 500 (index finger 500b in FIG. 8) supports the part of the trim fixing part 13a on the end 13j side.

While holding the clip 13 as described above, the worker moves the clip 13 as indicated by the arrow until the base portion 13b and the pressing portion 13c of the clip 13 are positioned near the opening of the groove portion 11d. When the base portion 13b and the pressing portion 13c of the clip 13 are positioned near the opening of the groove portion 11d, tension is applied to the trim 12, and wrinkles disappear.

The operator moves the base portion 13b and the pressing portion 13c of the clip 13 near the opening of the groove portion 11d, and then applies force with the index finger 500b to insert the base portion 13b and the pressing portion 13c into the groove portion 11d. When the bottom end 13d of the clip 13 reaches the groove bottom 11j of the groove portion 11d, or just before that, a part of the pressing portion 13c fits into the recessed portion 11h provided in the side wall surface 11g. This allows the operator to feel with the hand 500 that the insertion of the clip 13 into the groove portion 11d has been completed.

In addition, in the clip 13, the pressing portion 13c is formed to be flexible, so when the pressing portion 13c is inserted into the groove portion 11d together with the base portion 13b, the flexibility of the pressing portion 13c causes the pressing portion 13c to apply an outward pressing force against the side wall surface 11g, and the base portion 13b applies an outward pressing force against the side wall surface 11i.

In addition, as the base portion 13b is pressed against the side wall surface 11i, the return portion 13f is pressed into the side wall surface 11i. This causes the return portion 13f to engage with the side wall surface 11i, preventing the clip 13 from easily coming out of the groove portion 11d.

As described above, in the seat 1 according to this embodiment, the trim 12 can be fixed to the cushion pad 11 by the simple operation of pushing the base portion 13b and the pressing portion 13c of the clip 13, to which the edge portion 12a has been previously fixed, into the groove portion 11d of the cushion pad 11.

In addition, in the seat 1 according to this embodiment, the worker can insert the thumb 500a through the window 12d provided in the trim 12, press the end 13i of the trim fixing portion 13a with the thumb 500a, and insert the base portion 13b and the pressing portion 13c of the clip 13 into the groove 11d. At this time, the portion constituting the window 12d in the trim 12 is interposed between the end 13i of the clip 13 and the thumb 500a of the worker, and the window 12d functions as a buffer material, so that even when the worker repeatedly performs the work, the accumulation of fatigue in the hand 500 is prevented, and a decrease in workability is suppressed.

Therefore, the seat 1 according to this embodiment can achieve high workability when fixing the trim 12 to the cushion pad 11.

Furthermore, the cushion pad 11 according to this embodiment is provided with a recess 11f and a flexible groove 11e. The recess 11f is provided at a portion where the end 13i in the X direction is located when the base portion 13b and the pressing portion 13c of the clip 13 are inserted into the groove 11d. By providing the recess 11f at such a position, when attempting to remove the clip 13 from the groove 11d of the cushion pad 11, the worker inserts the thumb 500a into the window portion 12d and into the recess 11f. Then, the worker uses the thumb 500a to separate the trim fixing portion 13a from the back surface 11c of the cushion pad 11. This allows the base portion 13b and the pressing portion 13c to bend within the groove 11d.

The worker then applies force in the direction opposite to the arrow with thumb 500a inserted into recess 11f to cushion pad 11, bending the portion of cushion pad 11 between groove 11d and flexibility groove 11e. This widens the opening width of groove 11d, making it easier to remove base 13b and pressing portion 13c of clip 13 from groove 11d.

The clip 13 is removed from the cushion pad 11 as described above, for example, when replacing the trim 12.

As another example of a method for attaching the trim 12 to the cushion pad 11, the following method can be used. In this example, it is assumed that the worker's standing position (working position) is on the opposite side to the direction in which the trim 12 extends (the right side in the X direction in FIG. 8).

The worker inserts index finger 500b through window 12d provided in trim 12 and hooks end 13i of trim fixing portion 13a with index finger 500b. Then, with index finger 500b hooking end 13i of trim fixing portion 13a, clip 13 can be moved so as to be pulled toward the worker (right side in the X direction in FIG. 8) and base portion 13b and pressing portion 13c of clip 13 can be inserted into groove 11d.

By adopting the method according to the other example as described above, the trim 12 can be fixed to the cushion pad 11 without rotating the cushion pad 11 or moving the worker in relation to the worker's standing position. In other words, even if the trim fixing portion 13a of the clip 13 to which the edge portion 12a of the trim 12 is fixed in advance is located farther from the worker than the base portion 13b, the trim 12 can be fixed to the cushion pad 11 with high workability.

[Second embodiment]
A seat according to a second embodiment of the present invention will be described below. The seat according to this embodiment is different from the seat according to the first embodiment in the shape of the edge portion 22a of the trim 22, but is otherwise the same as the first embodiment. Therefore, the following description will focus on the differences.

1. Structure of Edge Portion 22a of Trim 22 The structure of edge portion 22a of trim 22 will be described with reference to FIGS. 9 and 10. FIG.

As shown in Figures 9 and 10, the edge portion 22a of the trim 22 according to this embodiment is also folded back at a folded portion (not shown) and fixed to the trim fixing portion 13a of the clip 13 at a fixing portion 22b. The edge portion 22a of the trim 22 has a side end covering portion 22d that extends outward in the Y direction beyond the side ends 13g, 13h of the trim fixing portion 13a. The side end covering portion 22d corresponds to the "enveloping portion."

As shown in FIG. 10, the side end covering portion 22d of the trim 22 is configured to hang down to cover the side ends 13g and 13h of the trim fixing portion 13a as shown by arrow B.

2. Method of Attaching the Trim 22 to the Cushion Pad 11 The method of attaching the trim 22 to the cushion pad 11 will be described with reference to FIG.

In this embodiment as well, when attaching the trim 22 to the cushion pad 11, first, the fixing portion 22b (see FIG. 10) of the trim 22 is sewn to the trim fixing portion 13a of the clip 13. Note that in this embodiment as well, the trim 22 extends to the left in the X direction beyond the end portion 13i (see FIG. 5) of the trim fixing portion 13a, and continues to the covering region that covers the front surface 11a and front surface 11b of the cushion pad 11.

The worker places the thumb 501a of the worker's hand 501 on the trim fixing part 13a and supports the side ends 13g, 13h of the trim fixing part 13a with the index finger 501b (see Figures 9 and 10). At this time, as shown in Figure 10, the side end covering part 22d of the trim 22 hangs down to cover the side ends 13g, 13h of the trim fixing part 13a, so that the side end covering part 22d is interposed between the index finger 501b of the worker's hand 501 and the side ends 13g, 13h.

While holding the clip 13 as described above, the operator moves the clip 13 until the base portion 13b and the pressing portion 13c of the clip 13 are positioned near the opening of the groove portion 11d, and then applies pressure with the thumb 501a to insert the base portion 13b and the pressing portion 13c into the groove portion 11d.

In the seat according to this embodiment, the trim 22 can be fixed to the cushion pad 11 by the simple operation of pushing (inserting) the base portion 13b and the pressing portion 13c of the clip 13, to which the edge portion 22a has been previously fixed, into the groove portion 11d provided in the cushion pad 11.

In addition, in the seat according to this embodiment, the worker can grasp the side ends 13g, 13h of the trim fixing part 13a by sandwiching the side end covering part 22d between them. In this case, the side end covering part 22d of the trim 22 functions as a buffer between the index finger 501b of the worker and the side ends 13g, 13h of the trim fixing part 13a, so that the accumulation of fatigue in the hand 501 can be suppressed even when the worker performs the task repeatedly.

Therefore, the seat according to this embodiment also achieves high workability when fixing the trim 22 to the cushion pad 11.

[Modification]
In the first embodiment, the trim 12 is provided with a window portion 12d, and in the second embodiment, the trim 22 is provided with a side end covering portion 22d, but the present invention may provide the trim with both a window portion similar to that of the first embodiment and a side end covering portion similar to that of the second embodiment. If the trim is provided with both a window portion and a side end covering portion, a worker who is attaching the trim to the cushion pad can select whether to use one or both of the window portion and the side end covering portion in consideration of his or her own workability. Therefore, this is advantageous in realizing high workability for many workers.

In the first and second embodiments, the seat 1 applied to the rear seats of an automobile is used as an example, but the present invention is not limited to this. For example, it can also be applied to seats applied to front seats, seats used indoors, etc.

In addition, in the first and second embodiments described above, the seat cushion 10 that supports the buttocks of a seated person is used as an example, but the present invention can also be applied to a seat back.

In the first and second embodiments, as shown in Figs. 2 and 5, a long clip 13 is used that follows the opening of the groove 11d, but the present invention does not limit the shape of the clip to a long shape.
