Description

The invention relates to a ventilation module for a two-wheeled helmet and to a two-wheeled helmet with such a ventilation module.

Two-wheeled helmets are designed to protect the wearer's head from injury. However, the helmet interior, which is surrounded by a helmet shell, is generally relatively poorly ventilated. This can lead to a significant reduction in comfort for the wearer.

It is therefore an object of the present invention to show new ways in the development of ventilation modules for venting two-wheeled helmets. In particular, an improved embodiment for such a ventilation module is to be created which, during operation, brings about improved ventilation of a two-wheeled helmet.

This object is achieved by the subject matter of the independent patent claims. Preferred embodiments are the subject matter of the dependent patent claims.

The basic idea of the invention is therefore to equip a ventilation module for a two-wheeled helmet with a U-shaped padded body that can be replaced and placed at least partially in a two-wheeled helmet. According to the invention, it is proposed to provide a fan in the padded body to convey air. With the help of this fan, air can be transported from the helmet interior to the outside, i.e. into the external environment of the two-wheeled helmet. This allows the helmet interior to be ventilated particularly efficiently. Since the fan is arranged in the padded body and thus at least partially surrounded by the padded body The fan does not have a noticeable impact on the comfort of the wearer of the two-wheeled helmet. In the event of an accident, the padded body also prevents the wearer of the two-wheeled helmet from sustaining head or neck injuries due to the fan located inside the helmet.

In detail, a ventilation module according to the invention comprises a substantially U-shaped cushion body for at least partial, preferably complete, arrangement in a two-wheeled helmet. According to the invention, a fan for conveying air is arranged in the cushion body. The fan can comprise a rotatable, in particular electrically driven, fan wheel with wheel blades or similar. The fan can be partially surrounded by the cushion body and in particular embedded in it. The cushion body thus prevents the fan arranged in the cushion body from being perceived in an unpleasant manner by a wearer of the two-wheeled helmet. Expediently, at least one air path through which air can flow runs in the cushion body, in which the fan is arranged so that it can convey air through the air path. However, the fan can also be arranged in the cushion body in such a way that an air inlet for introducing air into the fan and/or an air outlet for discharging air from the fan is arranged on the surface of the cushion body.

According to an advantageous development of the ventilation module according to the invention, the blower comprises an air inlet, preferably in the form of a nozzle, which protrudes, in particular upwards, from the cushion body. The air to be conveyed can be sucked into the blower via the air inlet. Alternatively or additionally, the blower in this development can have an air outlet, preferably arranged on the side of the blower, so that the respective blower is preferably designed as a radial fan. The air to be conveyed can be efficiently blown out of the blower via the air outlet and thus transported out of the helmet interior of the two-wheeler helmet.

In a further preferred embodiment, the U-shaped cushion body has a U-base and two U-legs protruding from the U-base on opposite sides. In this embodiment, the at least one fan is arranged in the U-base. If the ventilation module is used as a neck cushion in a two-wheeled helmet, the ventilation of the helmet interior can take place in the neck area.

According to an advantageous development of the ventilation module according to the invention, two fans can be provided in the cushion body, which are arranged next to one another, in particular in the U-base, in the cushion body. In this way, the air delivery capacity of the ventilation module can be increased. It is conceivable to design both fans so that they can be controlled separately from one another. In this way, the ventilation capacity that can be provided by the ventilation module can be varied over a particularly large air delivery capacity range and can therefore be adapted to suit the specific situation.

In a preferred embodiment, at least one through-opening can be formed in the cushion body, in which the at least one fan is inserted to convey air. The fan is thus arranged in the through-opening in such a way that it can suck in air via an air inlet and blow it out via an air outlet, whereby the desired conveyance of air is achieved.

According to a further advantageous development, a functional carrier can be provided in the cushion body, the material of which has a higher strength than the material of the cushion body. For example, rubber or cardboard can be used as the material for the functional carrier. In this development, the at least one fan is arranged on the functional carrier and can in particular be attached to the functional carrier. In this way, the fan can be arranged in a permanently stable and precisely positioned manner in the cushion body and can therefore also be positioned in the two-wheeler helmet using the ventilation module.

According to another advantageous development, an electrical power supply for supplying the blower with electrical energy is arranged in the padded body, in particular in one of the two U-legs or in both U-legs. Alternatively or additionally, in this development, a control/regulating device for controlling the blower can be arranged in the padded body, in particular in one of the two U-legs or in both U-legs. In this way, the ventilation module can be installed as a structural unit in the two-wheeler helmet. This means that separate electrical wiring of the blower after the ventilation module has been installed in the two-wheeler helmet can be omitted.

The invention further relates to a two-wheeled helmet, in particular a motorcycle helmet. The two-wheeled helmet according to the invention comprises a helmet shell which partially surrounds a helmet interior. The helmet shell has a lower helmet opening through which the helmet shell can be placed on a wearer's head. Furthermore, the two-wheeled helmet according to the invention comprises a preferably replaceable, in the area of the helmet opening at least partially arranged in the helmet interior, presented above and thus according to the invention Ventilation module. The advantages of the ventilation module according to the invention explained above are therefore transferred to the two-wheeled helmet according to the invention. The helmet shell can also have a front helmet opening that acts as a viewing window for the wearer of the motorcycle helmet. On an inside of the helmet shell facing the helmet interior, padded bodies - different from the padded body of the ventilation module - can be provided in various helmet shell sections, which increase the wearing comfort for the helmet wearer and further reduce the risk of injury for the helmet wearer in the event of an accident.

In a preferred embodiment of the two-wheeled helmet according to the invention, the ventilation module of the padding body can be designed as a neck pad, in particular a replaceable one. Such a neck pad increases the wearing comfort considerably when installed in a two-wheeled helmet. In addition, the neck pad can be easily removed from the two-wheeled helmet when it becomes worn.

The ventilation module, in particular the U-shaped padding, can be useful if it partially encloses the helmet opening. Alternatively or additionally, the ventilation module can protrude from the helmet interior through the helmet opening. Both measures increase the wearing comfort of the two-wheeler helmet when the ventilation module is used in the two-wheeler helmet.

According to an advantageous development of the two-wheeled helmet according to the invention, the ventilation module, in particular the U-shaped padding body, can be detachably attached to the helmet shell, in particular by means of a clip connection or by means of a clamping ring. This allows the ventilation module to be easily mounted on the two-wheeled helmet. The ventilation module can be removed from the helmet shell of the two-wheeled helmet just as easily, for example for replacement purposes.

According to an advantageous development, an air-permeable head cushion can be arranged in an upper area of the helmet interior. In this development, at least one air channel through which air can flow is formed between the helmet shell and the head cushion, which communicates fluidically with the at least one fan of the ventilation module, in particular with the air inlet of this fan, so that air can be sucked in from the air channel by means of the fan. Air can thus be conveyed particularly efficiently from various areas of the helmet interior via the air channel and transported out of the helmet interior by means of the fan.

In a preferred embodiment, the at least one fan can be arranged in the helmet interior and/or in the helmet opening in such a way that the air conveyed by the fan can be discharged from the helmet interior into an external environment of the two-wheeled helmet. Particularly preferably, the fan, in particular an air outlet of the fan, can communicate fluidically with an external environment of the two-wheeled helmet.

In a preferred embodiment of the two-wheeled helmet according to the invention, the U-base is arranged in a rear lower area of the helmet interior. In this embodiment, the two U-legs are arranged in a left lower and right lower area of the helmet interior. This allows the ventilation module to function as a neck pad and increases comfort for the wearer of the two-wheeled helmet.

Particularly preferably, the air channel can communicate fluidically with the at least one fan, in particular with the air inlet of the fan, by means of a spacer fabric.

According to an advantageous development of the two-wheeled helmet according to the invention, an air-permeable chin pad is arranged in a front area of the helmet interior above the helmet opening. In this development, an additional fan for conveying air into the air channel is arranged in and/or on the chin pad. Additional air can be blown into the air channel using the additional fan. In conjunction with the at least one fan of the ventilation module, a circulation of air in the helmet interior can also be brought about, which is perceived as pleasant by the wearer of the two-wheeled helmet.

Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

The Figure 1 shows in perspective an example of a ventilation module 1 according to the invention. The Figure 2 shows a rear view of the ventilation module 1, the Figure 3 a top view of the ventilation module 1 The Figure 4 shows a bottom view of the ventilation module 1.

According to the Figures 1 to 4 The ventilation module 1 comprises a substantially U-shaped cushion body 2 for arranging in a Figures 5 and 6 shown two-wheeled helmet 20. The U-shaped padded body 2 according to the Figures 1 to 4 can be designed as a replaceable neck pad 2a for the two-wheel helmet 20 and have a U-base 5 and two U-legs 6a, 6b protruding opposite from the U-base 5. A first and a second blower 3a, 3b, each for conveying air L, are arranged in the cushion body 2.

A first and a second through-opening 11a, 11b are formed in the U-base 5 of the cushion body 2, into each of which one of the two fans 3a, 3b is inserted to convey air L. The two fans 3a, 3b and thus also the two through-openings 11a, 11b are arranged next to one another in the U-base 5. Each of the two fans 3a, 3b comprises a nozzle-like air inlet 4a, 4b which protrudes upwards from the cushion body 2. In addition, each of the two fans 3a, 3b has an air outlet 8a, 8b arranged on the side of the fan 3a, 3b (cf. Figures 1 , 4 ). The two fans 3a, 3b are therefore preferably designed as radial fans. The two fans 3a, 3b are arranged in the associated through opening 11a or 11b in such a way that they can each suck in air L via the air inlet 4a or 4b and blow it out via the air outlet 8a or 8b, whereby the desired conveyance of the air L is achieved.

A material for the functional carrier 7 can be, for example, rubber or cardboard. The two fans 3a, 3b can be arranged on the functional carrier 7 and also attached to it.

In the example scenario, as in Figure 3 As shown schematically, an electrical power supply 9 for supplying the blower 3a, 3b with electrical energy is arranged in a first 6a of the two U-legs 6a, 6b. In one variant, the two blowers 3a, 3b can also be connected to an external electrical Power supply (not shown). In the example scenario, a control/regulation device 10 for controlling the two fans 3a, 3b is arranged in the first U-leg 6a. Alternatively, the control/regulation device 10 can also be arranged in the second U-leg 6b (not shown).

The Figures 5 to 8 show an example of a two-wheeled helmet 20 according to the invention in the form of a motorcycle helmet 20a. The Figure 5 shows a front view, the Figure 6 a side view that Figure 7 a sectional view of the two-wheeled helmet 20. The Figure 8 shows a bottom view of the two-wheel helmet 20.

According to the Figures 5 to 8 the two-wheeled helmet 20 comprises a helmet shell 21 which partially surrounds a helmet interior 22. A vertical direction HR extends from a helmet underside 36 to a helmet top 37 of the two-wheeled helmet 20. A transverse direction QR extends perpendicular to the vertical direction HR from a right helmet side 38 to a left helmet side 39 of the two-wheeled helmet 20. A longitudinal direction LR extends perpendicular to the vertical direction HR and also perpendicular to the transverse direction QR from a helmet back 40 to a helmet front 41 of the two-wheeled helmet 20. The helmet shell 21 has a lower helmet opening 23 with respect to the vertical direction HR, through which the helmet shell 21 can be placed on a head of a wearer (not shown) of the two-wheeled helmet 20. A viewing opening 26 can be provided in the helmet front 41 for the wearer of the two-wheeled helmet 20, which can be covered with an adjustable translucent visor 26a if necessary.

As the Figures 5 to 8 As can be seen, the two-wheeled helmet 20 according to the invention comprises a ventilation module 1 according to the invention. The ventilation module 1 is designed separately from the helmet shell 21 as a replaceable neck pad and in the area of the helmet opening 23 partially arranged in the helmet interior 22 or inserted into it. The U-shaped padded body 2 of the ventilation module 1 can be detachably attached to the helmet shell 21, for example by means of a clip connection (not shown) or by means of a clamping ring (not shown). The ventilation module 1 can protrude from the helmet interior 22 through the helmet opening 23 as shown and also partially enclose the helmet opening 23 with its U-shaped padded body 2.

Furthermore, the U-base 5 of the cushion body 2 is arranged in a rear lower region 29 of the helmet interior 21 in the region of the helmet opening 23 with respect to the longitudinal direction LR and the vertical direction HR. The two U-legs 6a, 6b are arranged in a left lower region 30a and in a right lower region 30b of the helmet interior 22 with respect to the longitudinal direction LR and the vertical direction HR, respectively, in the region of the helmet opening 23.

In the example scenario, an air-permeable head cushion 25 is arranged in an upper area 24 of the helmet interior 22 at a distance from the helmet shell 21. In a space 28 between the helmet shell 21 and the head cushion 25, an air channel 27 through which air L can flow is formed, which communicates fluidically with the respective air inlet 4a, 4b of the two fans 3a, 3b. As a result, air L can be sucked in from the air channel 27 by means of the two fans 3a, 3b. The air L conveyed by means of the two fans 3a, 3b can be blown out of the helmet interior 22 into an external environment 35 of the two-wheeled helmet 20 through the helmet opening 23 via the two air outlets 8a, 8b. The two fans 3a, 3b are thus arranged in the helmet interior 22 or in the area of the helmet opening 23 in such a way that the air L conveyed from the air duct 27 by means of the fan 3a, 3b can be discharged or blown out from the helmet interior 22 into an external environment 35 of the two-wheeled helmet 20. For this purpose the respective air outlet 8a, 8b of the two fans 3a, 3b communicates fluidically with the external environment 35. The air duct 27 can be as in Figure 7 indicated by means of a spacer fabric 31 fluidically communicate with the air inlets 4a, 4b of the blower 3a, 3b.

Optionally, an air-permeable chin pad 33 (cf. Figure 7 ). An additional blower 34 for conveying air L into the air channel 27 can be arranged in the chin pad 33. By means of the additional blower 34, additional air L can be blown into the air channel 27. In interaction with the two blowers 3a, 3b, air L can also be circulated in the helmet interior 22.
