Protective devices for protecting a two-wheeled vehicle

description

The invention relates to protective devices for the protection of a two-wheeled vehicle according to claims 1, 16 and 18.

Protective elements for two-wheelers are known from the prior art, which are inflatable in the manner of a passenger car airbags and should absorb energy of a Aufsassen the two-wheeler in collision. For example, such a protective element is described in GB 1462125.

However, many accidents involving two-wheeled cyclists are not collisions, but are single-occupational accidents, that is to say two-wheeler crashes involving two-wheeled vehicles, due in particular to driving errors or poor weather conditions. Such falls often result in abrasions, bruises, and / or fractures in various body regions of the abdomen (especially at the head, neck, shoulders, arms, pelvis, and / or legs). In addition, the incarcerations of smaller two-wheelers (eg <125 cc) often suffer serious injuries in the event of falls, since smaller two-wheelers are often driven without protective clothing or only with a protective helmet. The problem to be solved by the invention is therefore to improve the protection of a two-wheeled vehicle.

This problem is solved by the provision of a protective device having the features of claim 1, claim 16 or claim 18.

Thereafter, a protection device for protecting a two-wheeled vehicle is provided, with

- At least one inflatable protective element, which is designed and attached to the two-wheeler, that it is inflated in an imminent fall of sitting with the bicycle and comes as a result of the fall on the road to rest that the Aufsasse on the protective element impinges, wherein

- The protective element is such that, for at least a limited period of time, it withstands the frictional forces occurring between it and the roadway after impacting the vehicle.

The protective element thus protects, in particular in the case of lateral falls of the seat against injuries due to the (in particular first) impact with the road and / or from abrasions when sliding on the road. For example, the inflated protective element lays like a protective carpet between the falling seats and the roadway. The protective element (in particular its thickness), however, is not necessarily designed to counteract injuries due to bruises.

The fact that the protective element "withstands" the frictional forces does not necessarily mean that it is not damaged by the action of the frictional forces, however, at least for a certain period of time after inflation no damage occurs which leads to a significant escape of gas from the protective element.

For example, at least a portion of the protective element is such that its resistance to the frictional forces occurring upon contact with the roadway is at least approximately equal to a position of a gas bag material of a passenger car airbag or higher than that of a layer of such a gas bag material. An airbag material of a car Airbags is in particular a textile fabric, for example a fabric of plastic threads (such as polypropylene threads).

Accordingly, the protective element may comprise at least one layer of material formed of a plastic fabric, which limits an inflatable volume. Of course, it is also conceivable that the protective element has a plurality of interconnected (for example, sewn or glued) layers of material which limit the inflatable volume of the protective element.

It is also possible that the fabric from which the protective element can be formed, with a gas-sealing coating (for example, a silicone coating) is provided. The coating is used in particular to extend the service life of the inflated protective element.

According to another embodiment of the invention, an inflatable volume of the protective element is limited by at least one layer of material which has at least one protective layer at least at a portion of an outside facing the lane during the fall outside. The protective layer is in particular connected to the material layer, e.g. sewn or glued on. However, it is also conceivable that the protective layer is produced in the form of a coating, e.g. in the form of a material film or a material film. Also possible is a coating that is not necessarily used as a protective layer, but to allow a better sliding of the protective element on the road and / or the fallen sitting on the protective layer.

For example, the protective layer is formed as a sacrificial layer, i. As a material layer, which is damaged or destroyed by the effect of friction with the road. The sacrificial situation thus absorbs frictional forces that can lead to their destruction. The material layer (main layer), which limits the inflatable volume of the protective element, however, is protected.

It is quite possible that the protective layer is made of the same material as the main layer; for example, from the above-mentioned tissue. However, this is not mandatory. Rather, the protective layer may also be formed of another material (such as silicone or a ceramic), for example, has a higher resistance to friction with the road than the main layer. Of course, it is also not mandatory to even provide a protective layer in addition to the main layer. It is also conceivable, for example, that the main layer itself is so resistant to the friction with the roadway that no additional protective layer is needed.

According to another variant of the invention, the protective element is designed such that it has a coefficient of friction with respect to the road surface that is higher than that of an outer side of the bicycle or that substantially corresponds to that of an outer side of the bicycle.

A substantially identical coefficient of friction of the protective element (ie, in particular its outer side, which will arise on a lintel on the roadway) relative to the outer side of the bicycle (ie in particular an outer side of a fairing of the bicycle) serves, in particular, relative to the position of the protective element to keep at least approximately constant to the bicycle after the fall, ie to obtain a constant distance as possible between the protective element and thus the fallen vehicle occupants and the bicycle to a collision of the fallen (and for example still slipping on the road) with the two on to prevent the protective element lying on seats. A higher coefficient of friction of the protective element may even lead to a removal of the two-wheel from the protective element and thus from the fallen on the protective element located Aufassen, or at least ensure a sufficient distance between the bicycle and the seating; in particular in such a way that the two-wheeler slides forward. The protective element is also particularly dimensioned so that - based on a arranged on a bicycle protection device - immediately after inflation (ie before it rests on the road and thus still at least approximately parallel to a plane spanned by the two-wheel longitudinal and -high axis plane and extending laterally of the cup) extends at least from a thigh area of the cup to its shoulder area. Thus, at least the upper body portion of the occupant after the fall on the protective element will arise. Of course, it is also conceivable that the protective element also provides protection for the leg area (in particular the knee area) and / or the neck and head area. The protective element is in particular designed such that it unfolds past the seating, especially laterally past this along the two-wheeled longitudinal axis, diagonally (approximately obliquely to both the two-wheeled longitudinal axis and the two-wheel height axis) or spatially around the Aufsassen around. To inflate the protective element, the protective device comprises at least one gas generator, for example in the form of a pyrotechnic gas generator, a cold gas generator or a hybrid gas generator. According to another embodiment of the invention, the protective device comprises at least two inflatable protective elements and at least one gas generator for inflating the two protective elements. It is conceivable that a common gas generator is provided, which serves to inflate both protective elements. It is also possible, however, that there are two separate gas generators, each serving to inflate one of the protective elements.

The two protective elements are located on different sides of the bicycle to ensure protection against falls, regardless of the lateral tilting directions. It is also conceivable that the protective device is designed to inflate both protection elements in a fall, in particular to achieve a mutual stabilization of the protective elements and the best possible protection of the collapsing Aufsassen. It is noted that the signal for inflating the two protective elements emanates in particular from a control unit of the protective device. The control unit may also be part of a central control unit of the bicycle.

However, it is also conceivable that depending on the tilting direction of the camber only that of the two protective elements is inflated, which is located on the side of the bicycle, which will be on the vehicle floor. Of course, it is also possible that the protective device comprises more than two inflatable protective elements. For example, more than one protective element can also be located on one side of the two-wheeler, which are arranged one behind the other along the two-wheeled longitudinal axis, for example. The protective device according to the invention may moreover comprise a holding device movable from a starting position into an inserted position, on or in which the inflatable protective element is arranged. The protective element is brought by moving (in particular pivoting) of the holding device in the use position in its inflation position, wherein the inflation of the protective element, for example, only after reaching the inflation position (ie when the Holding device has reached the insertion position) begins. Of course, it is also possible that is begun with the inflation of the protective element already during the movement of the holding device in the use position. The movement of the holding device is triggered in particular analogously to the activation of the gas generator for inflating the protective element by a control signal of a control unit.

For example, holding device is additionally designed so that it itself contributes to a protection of the absorption in a fall. So she can e.g. be designed in the manner of a (in particular laterally attachable to the bicycle) guard bracket, which positions not only the protective element in the insertion position, but also realizes an additional lateral protection.

It is also possible that the protective element has at least one structure for its stabilization in the inflated state; e.g. prevents the structure accidental early removal of the protective element of the bicycle. For example, this structure is a tether or a gas-filled volume. Thus, for example, attaching a tether from the inflatable protective element to the bicycle, for example, being secured to the bicycle (in particular, to a portion of a fairing of the bicycle) and / or to a module housing in which the inflatable protective element is housed prior to inflation. The inflatable volume, for example in the form of a gas-filled tube, such as longitudinal or transverse tubes, or a region (chamber) of the protective element, for example, extends along a portion of an outside of the inflatable volume and may also extend beyond the inflatable volume , It is also conceivable that at least a portion of the edge of the protective element is shaped so that it acts as a stabilizing structure. For example, the edge has a greater thickness than a limited by him inner region of the protective element.

The protective device according to the invention is particularly reversible, i. It can be manually or automatically returned to its initial state after a trip (for example, a false trip). It is also conceivable that the protective device is easily replaceable after a triggering.

According to a further embodiment of the invention, the protective device comprises a fastening device for tool-free fastening of a free portion of the inflated Protective element on the bicycle to allow driving on the bicycle after activating the protective device. In particular, the unfolded protective element can be temporarily fixed to the bicycle by means of the fastening device after a false triggering of the protective device or after only a slight accident. A "free section" of the protective element is a section which is not (at least not anymore) fixed directly to the bicycle and thus movable relative to the bicycle.

It is also conceivable, for example, for a module housing of the protective device in which the inflatable protective element is accommodated before the protective device is triggered to be designed so that the unfolded protective element can be stowed again in the module housing in a simple manner at least in sections Example under folding, plugging and / or rolling of the protective element). It is also possible to provide instructions for folding the protective element before re-stowing. For example, such a guide is attached to the bicycle or the protective element; approximately printed on the protective element or connected to the protective element (for example, sewn).

It is also conceivable that stowing the unfolded protective element is a different from a module housing of the protective device recording attached to the bicycle. The shot is e.g. formed in the form of a box or a bag, wherein in particular the bag can be fixed to the protective element or to the module housing. Furthermore, the recording could serve to send the protective element (in particular for analysis after the accident).

The fastening device may e.g. also be designed to prevent the stored after unfolding in the module housing or recording protective element moves out of the module housing or the receptacle (swells out).

For example, the fastening device comprises a fastening element with which the unfolded protective element can be attached to a part of the bicycle (in particular a section of the lining, a frame section of the bicycle or a section of the module housing). For example, the fastening element is a clip, a (in particular knottable) tape (eg a Velcro strip or a rubber band), a rope, in Velcro band, a holding bag, a holding bag or a holding box. It is also conceivable that the fastening element is connected to a part of the module housing, such as a cap. Such a fastening element can also serve to fix the protective element brought back into the module housing or the additional receptacle there.

In a second aspect, the invention relates to a protective device for protecting a two-wheeled vehicle, in particular as explained above

- At least one inflatable protective element, which is designed and arranged on the bicycle, that it is inflated in an impending fall of the Aufsassen with the bicycle and comes as a result of the fall on the road to rest so that the falling Aufsasse impinges on the protective element , in which

- The protection device is designed such that the protective element is movable in the inflated state after the fall relative to the bicycle. In particular, the protective device allows a moving away of the fallen bicycle from the resting on the road surface protection element and thus of the fallen seating. For example, the protective device is designed so that the inflated protective element in the course of the fall (especially after a collision of absorption on the protective element) detaches from the bicycle to allow movement of the bicycle and the taking away from each other.

It is conceivable, for example, that the protective element with a tether or other connecting element initially connected to a part of the bicycle (for example, with a cladding of the bicycle) or a module housing of the protective device, which connection is released in the course of the fall. For example, it is possible that the tether breaks off the bicycle and thus releases the protective element. Also possible is an active mechanism that separates the connecting element from the bicycle in response to a control signal.

In a further aspect, the invention relates to a protective device for protecting a Aufsas- sen a two-wheeler, in particular according to an embodiment designed as explained above, with - At least one inflatable protective element, which is designed and arranged on the bicycle, that it is inflated in an imminent fall of the absorption with the bicycle in a protective position and as a result of the fall on the road to rest so that the falling Aufsasse on the protective element impinges; and

- A device for removing the inflated protective element from the protective position.

For example, the device for removing the inflated protective element comprises a return device with which the protective element can be moved counter to its deployment direction.

The protective element can be removed by means of the return device, e.g. towards a module housing in which the protective element was arranged prior to its activation, are moved. It is also conceivable, in particular, for the return device to have a return spring (coupled to the protective element, for example, via a tether), which is tensioned by the deploying protective element. The recovery of the unfolded protective element effected by the return device (in particular the return spring) takes place, for example, in FIG. manually by actuation of a corresponding actuating device which triggers the retrieval of the protective element.

It is also conceivable, moreover, that the protective element has at least one vent opening, via which gas can escape from the protective element to the outside. The escape of gas from the protective element reduces the internal pressure, thereby facilitating the retrieval of the protective element. The vent opening of the protective element can also be realized without the return device. According to another embodiment of the protective device according to the invention, the device for removing the protective element for separating the inflated protective element is formed by the bicycle. For example, the device for removing the protective element comprises fastening means, via which the protective element is detachably fastened to a component of the bicycle. In particular, the fastening means are designed so that a manual release of the inflated protective element of the bicycle is possible in a simple manner or the protective element triggers after a period of time after its blowing by itself of the bicycle. It is conceivable, in particular, that the protective element is fixed to the bicycle by means of a holding element (for example a holding plate), wherein the holding element can be detachably connected to the bicycle Two-wheeler is connected. It is also possible that the protective element is housed in a module housing which is attached to the bicycle, wherein the attachment of the module housing is designed so detachable that the complete module can be easily removed by hand. For example, the protective element or the module (in particular the module housing) or the holding element coupled to the protective element or the module housing is connected to the bicycle by latching connection.

It is also possible that the device for removing to separate the inflated protective element is formed by the bicycle; e.g. the apparatus comprises a cutting edge, a knife and / or a scissors-type device (with two cutting edges which are movable towards each other), with which e.g. a tether or other element, via which the protective element is connected to the bicycle, can be severed. It is also conceivable that the device comprises a weakening (for example in the form of a perforation or a tear seam) of such a tether or other element.

The invention also relates to a two-wheeler with a protective device as explained above. For example, the protective element (or the module) of the protective device before being triggered in or on a seat, a running board, a trim part, a handlebar, a frame, a protective or crash bar (which is automatically moved to a protective position in a fall) or arranged in a lower area (eg in the area of a bow thruster) of the bicycle. In particular, the protective element is arranged in or on a side trim part, a trim of the running board, a front trim, an interior trim and / or a trim of a cockpit of the bicycle. It is generally possible that the module (in particular the module housing) is arranged such that it extends at least substantially parallel to one through the Zweiradlängs- and -höhenachse. However, it is also conceivable that the module is oriented transversely, i. parallel to a plane which is spanned by the two-wheel longitudinal and transverse axis.

In particular, the bicycle also comprises at least one sensor for detecting a tilting angle and / or a tilting speed of the bicycle, which cooperates with the protection device in such a way that it is triggered as a function of the detected tilting angle and / or the detected tilting speed (eg at tilting angles over 50 ° and eg in an expected Duration of about 120ms). The protective device according to the invention comprises, as already mentioned, in particular also a control unit for detecting and evaluating the sensor data and for generating and transmitting a triggering signal to the gas generator for inflating the protective element.

It is also conceivable that the bicycle at least one (in particular optical) sensor for detecting a distance between a structure of the bicycle (for example, a structure of a fairing of the bicycle) and the road and / or a sensor for detecting a contact between a structure of the bicycle (In turn, in turn, a cladding of the bicycle) and the roadway. Furthermore, infrared sensors can measure the distance between the trim panel and the roadway to trigger the protection device.

Of course, it is also possible that other data of the two-wheeler are used to detect an imminent (especially unavoidable) fall; e.g. also data of other sensors such. an acceleration sensor or a sensor that detects a loss of lateral tire grip. In addition, the triggering of the protective device can additionally be effected as a function of the driving speed (for example, no triggering takes place even at high tilt angles if the driving speed is below a minimum value). In addition, it is conceivable that the protective device according to the invention is triggered not only in the event of an imminent fall (ie a lateral overturning), but also in the event of an impact or imminent impact of the bicycle (active or passive), e.g. in a lateral and / or oblique collision.

The invention further relates to a bicycle having a protective device configured as described above, the bicycle comprising a restraint system for limiting movement of the vehicle relative to the protective element of the protective device at least prior to activation of the protective device. The restraint system has in particular a safety belt (eg a two-point belt) and / or a rigid safety element (eg a safety bar). The safety belt or the safety element in particular fix a pelvic area of the sitting on the bicycle. The restraint system may be configured to counteract, upon activation of the protection device, movement of the ab- sorpt relative to the protection element. In particular, the restraint system holds the cradles in a defined position relative to the protective element; For example, if this does not leave the bicycle after inflation.

However, it is also conceivable that the activated protective element performs a relative movement relative to the bicycle (cf the above-described second aspect of the invention). In particular, for this embodiment of the protective device can be provided that the restraint system is designed so that it allows for activation of the protective device, at least to a certain extent, a movement of the seating relative to the bicycle and with the protective element. It is conceivable, for example, that the restraint system releases the fixation of the seating when the protective device is triggered; e.g. For example, the seat belt or safety bar may at least partially disengage from the bicycle so as to relieve or eliminate the limitation on the movement of the vehicle relative to the bicycle.

1 shows a perspective view of a two-wheeler 1 in the form of a scooter, which is equipped with a protective device 2 according to the invention. The protective device 2 comprises an inflatable protective element 21, which is inflated with the bicycle 1 in the event of a fall or at least in the event of a threat of a fall 3 (in particular of a driver). In Figure 1, the protective element 21 is shown immediately after its inflation and thus before a complete overturning of the Aufsassen 3 on a roadway. To inflate the protective element 21, the protective device 2 comprises a gas generator, which is not shown in Fig. 1. In addition, the protective element 21 is located prior to triggering, in particular in a mounted on a structure of the bicycle 1 module housing (also not shown in Figure 1). In the module housing and the gas generator can be accommodated.

At the time instant shown in FIG. 1, immediately after inflation, the protective element 21 extends laterally next to the seat 3 in such a way that it covers at least one body region from the shoulder to the thigh region. Correspondingly, the blown-on protective element 21 has a substantially planar, expanded shape in order to protect the housing 3 as well as possible in the event of a collision with the roadway after the two-wheeler 1 overturns sideways. In particular, with the protective element 21 abrasions caused by Friction with the roadway after the fall could occur, prevented or mitigated. It should be noted that FIG. 1 is used in particular to illustrate the protective element 21. Of course, the activation of the protective element 21 can only take place at larger tilt angles.

In order to achieve the best possible protective effect, the protective element 21 is moreover such that it can withstand the frictional forces occurring between it and the roadway, at least for a limited period of time after the impact of the seating device 3 on the protective element 21. For this purpose, the protective element 21, for example, some sections 21 1, which have a relation to the frictional forces particularly resistant material (for example, a durable plastic such as Cordura or a Kevlar fabric). The sections 21 1 are in particular sections of an edge of the protective element 21. Of course, it is also possible that, alternatively or in addition, other sections of the protective element 21 have the resistant material or else the entire protective element 21 is formed from such a material.

FIG. 2 shows various stages of a fall of a two-wheeled vehicle 1 equipped with a protective device 2 according to the invention. The protective device 2 comprises a protective element 21 designed, for example, in the manner of the protective element of FIG. Figure 2A illustrates the bicycle 1 and the cradles 3 in the normal driving position, i. before the fall.

However, once sensors of the bicycle 1, e.g. detect a tilting angle of the bicycle about its longitudinal axis and / or a tilting speed exceeding a predetermined limit value, activation of the protection device 2, i. an inflation of the protective element 21 (FIG. 2B). Analogously to FIG. 1, the protective element 21 unfolds laterally next to the vehicle occupant 3, and of course on the side to which the bicycle 1 tilts.

Figure 2C shows the two-wheeler 1 and the Aufsassen 3 after the fall, ie the emergence of the two-wheeler 1 and the Aufsassen 3 on a lane 1 00. The Aufsasse 3 strikes in particular with his upper body area (ie in particular with his shoulder and his thorax region) the already resting on the roadway 100 protection element 21. The protective element 21 thus prevents immediate contact larger body areas of the Aufsassen 3 with the roadway 100, which heavier injuries of the absorption is counteracted as a result of the fall. The protective element 21 can furthermore be designed such that it counteracts a movement of the fallen bicycle 1 and the vehicle occupant 3 together. For example, the protective element 21, at least on the side with which it comes to rest on the road surface, a corresponding coefficient of friction; For example, a friction coefficient that is greater than a (for example, average) friction coefficient of an outer side of the bicycle 1 (in particular, an outer side of a fairing of the bicycle 1).

After the fall, it comes in particular to a rotational movement of the Aufsassen 3 and the two-wheeled first Depending on the respective coefficients of friction (the outside of the bicycle 1 or the protective element 21), a substantially common rotation of the bicycle 1 and the protective element 21 (FIG. 2D, indicated by an arrow R) on the roadway 100 or a separate rotation takes place in such a way that the bicycle 1 and the protective element 21 (and therefore the bag 3) move away from each other.

The rotation of the bicycle 1 and the protective element 21 can result in the protective element 21 turning away below the seat 3 until it finally slips off the protective element 21 (FIG. E). The slipping of the Aufsassen in this phase of the fall may well be desirable to avoid moving away of the Aufsassen 3 of the two-wheeled vehicle 1 and thus a collision with the bicycle 1 as possible. At this point in time, the crashed uprising has already lost speed, so that the risk of injury in the event of contact with the roadway 100 after sliding off the protective element 21 is significantly lower than immediately after the fall.

The common rotation of the two-wheeler 1 and the protective element 21 is supported by the fact that the protective element 21 is coupled via a connecting element in the form of a tether 213 even after the fall with the bicycle 1. The tether 213 is shown in FIG. 2E.

Figure 3 shows a modification of Figure 2, according to which the protective element 21 is not fixed, but releasably connected to the bicycle 1. The detachable connection has the consequence that the 3 Aufsasse after impact on the roadway 100 together with the protective element 21 of the bicycle 2 can move away (Figure 3E), on the one hand to avoid collision with the bicycle 1 and on the other hand injury by contact with the roadway 100 as possible. The releasable connection of the protective element 21 with the bicycle 1 can be realized, for example, that similar to Figure 2E Although a tether is present, which initially connects the protective element 21 with the bicycle 1, which is so connected to the bicycle 1, that it dissolves when exposed to a predetermined force of the two-wheeled vehicle 1. For example, the tether has a suitably designed weakening. It is also conceivable, however, an active mechanism that separates the tether (or other connection element) between the protective element 21 of the bicycle 1 to a control signal out.

FIG. 4 schematically shows a module 20 of the protective device 2 according to the invention, which comprises a module housing 22 and the protective element 21 accommodated folded in the module housing 22. The module 20 may also include a gas generator 26, which is also approximately at least partially disposed in the module housing 22. The gas generator 26 is connected to an electrical line 261 for transmitting an ignition signal.

The module housing 22 is detachably connected to a structure (for example, a portion of a fairing) of the bicycle 1 via a fixing mechanism. The attachment mechanism is adapted to release the module housing 22, and thus the module 20, in response to a control signal so that it may detach (e.g., manually) from the bicycle 2 or become detached therefrom. For example, such an active fastening mechanism comprises pin-like connecting elements 23a, 23b, which engage in recesses or indentations of the module housing 22 and fix the module 20 in this way initially on the bicycle 1.

At least one of the pins (in this case the lower pin 23a) is movable from the fastening position (downward) shown in FIG. 4 into a release position in which it no longer fixes the module to the bicycle. For example, the movement of the pin 23a is electromagnetic, wherein, for example, a spring 25 may be present which initially presses the pin 23a against the module housing 22. However, against the force of the spring 25, the pin 23a can be moved out of the mounting position into the release position. Figures 5 - 18 show further embodiments of the protective device according to the invention, in particular its protective element 21 and the attachment of the protective device 2 to the bicycle 1.

It is conceivable, for example, that the protective element 21 has at least one recess and / or recess 214, which serves in particular to reduce the load on certain body regions of the Aufsassen 3 after the impact on the road. For example, as shown in FIG. 5, the recess 214 may be located in the region of the shoulder region and / or the upper arm of the seat 3. It is conceivable for the recess 214 to be oval and substantially vertical, as also shown in FIG. However, it is also possible a different orientation of the recess / indentation, for example, obliquely down the front (Figures 6 and 7) to adapt to a position of the arms of the Aufsassen 3 (as a driver) while driving.

As already mentioned above, the protective device according to the invention has in particular a module 20 formed at least from a module housing and the protective element 21 arranged in the module housing. It is also conceivable that a gas generator 26 for inflating the protective element 21 is part of the module 20 and can be used e.g. also located in the module housing.

The module 20 (with the gas generator 26) may for example be mounted in the region of a seat 1 1 of the bicycle 1 (Figure 5). It is possible in particular that the module 20 is positioned in the seat 1 1 or under the seat 1 1.

However, other positions of the module 20, for example, on a front portion 12 (which is in particular designed as knee and / or front protection) of a trim part of the bicycle 1 are also conceivable. see. FIG. 6, according to which the module 20 is arranged in a lower section (for example above a running board 13) of the section 12. The protective element 21 is dimensioned in dependence on the position of the module 20. Thus, the protective element 21 of Figure 6 extends from a lower leg region of the tray 3 to its head (relative to its state shown in Fig. 6 immediately after inflation of the protective element 21 and before resting on the road). It is also possible to mount the module 20 in an upper area of the front trim section 12 (at the level of a knee of the seat 3); FIG. 7. In this case, the protective element 21 may have a smaller inflatable volume which, for example, extends from a knee area to the head of the cup 3, as shown in FIG.

Another variant is to attach the module 20 in the region of the footboard 13 of the bicycle 1, as shown in Figure 8. The protective element 21 in this case is dimensioned so that it extends immediately after inflation as shown in Figure 8 over substantially the entire body portion of the cup 3 except for the head (which is usually covered with a protective helmet).

It should be noted that it is not mandatory that the gas generator 26 is arranged together with the module housing of the module 20. Rather, it is also conceivable, unlike in FIGS. 5-8, that the gas generator 26 is placed elsewhere and, e.g. for inflating a plurality of protective members 21 (e.g., arranged on different sides of the bicycle 1 as shown in Fig. 15).

Figures 9 - 1 1 relate to other ways to attach the module 20 with the protective element 21 to the bicycle 1. According to these embodiments, the protective device 2 next to the module 20 comprises a holding device 30, which can be brought from an initial position (solid line) in an inserted position (dashed line). The holding device 30 has two elements 31, 32, which are connected to one another via a hinge, and each with an end remote from the joint at a portion of the bicycle 1 (namely at the front portion 12 of the panel or in the region of the footboard 13th ) are articulated. The articulation of the two elements 31, 32 with each other on the one hand and with the bicycle 1 on the other hand allows pivoting of the holding device 30 from the starting to the use position (in particular about an at least approximately transverse to the longitudinal axis of the bicycle 1 axis).

The module 20 is arranged on the upper element 31 in the exemplary embodiment of FIG. 9. After triggering the protective device 2, the holding device 30 moves into the (for the deployment of the protective element 21 optimal) use position, wherein the gas generator for inflating the protective element 21 is already activated during the movement of the holding device 30 in the insertion position or until it reaches the insertion position.

FIG. 10 shows a further variant of a movable holding device 30. The holding device 30 is arranged in sections under the seat 1 1 of the bicycle 2 and has a (front) section 33 which is movable (in particular via a hinge connection) with a rear section 34 the holding device 30 is connected. By an activation signal, the front portion 34 is brought into the insertion position, whereupon the attached to the front portion 34 protective element 21 unfolds (Figure 10). It is also conceivable that the front portion 34 is articulated directly to a structure of the bicycle 2 (the rear portion 34 would not be required).

The holding device 30 can also be designed so that it contributes to the protection of the Aufsassen 3. For example, the holding device 30 is designed in the form of a protective strap 301, as shown in FIG. 11. The protective bow 301 pivots after triggering of the protective device from an initial position to an insertion position (about an axis extending at least approximately parallel to the longitudinal axis of the bicycle 1) in which it is located laterally of the seat 3 and thus provides this additional lateral protection and in particular an additional Protective distance for the leg area of the Aufsassen generated. At the same time, the protective element 21 of the protective device 2 is attached to an inner side of the retaining clip 301. The protective strap 301 can thus also stabilize the protective element 21.

The guard 301 of Figure 1 1 is located in the region of the seat 1 1 of the bicycle. 1 However, it is also conceivable that the guard, to which the protective element 21 is attached, is mounted elsewhere on the bicycle 1.

A further variant of the positioning of the module 20 is shown in Fig. 12, after which the module 20 in the region of an outer portion of a handlebar 1 of the bicycle 1 or a handlebar cover is arranged (Figure 12).

FIGS. 13 and 14 relate to possibilities of connecting the protective element 21 of the protective device 2 according to the invention to the bicycle 1. According to FIG. 13, the protective element 21 is similar to that of FIG. 7 in a front section 12 of a trim part is attached along a front edge portion 212 to an inside of the trim piece portion 12 (for example, via fasteners such as fastening clips). The module 20 (in particular the module housing) is designed, for example, elongate, wherein the module housing, for example, from a portion of the front portion 12 of the trim piece in the vicinity of the footboard 13 to an upper portion of the front portion 12 of the trim piece. Alternatively, an extension of the module 20 along lateral portions of a steering column is possible.

Also possible is an attachment of the protective element 21 via at least one tether 213, as shown in Figure 14. There is a lower (the footboard 13 facing) edge portion of the protective element 21 via the tether 213 with a lower portion (in particular of the running board 13) of the bicycle 1 is connected. The tether 213 serves in particular to stabilize the protective element 21 after it has been inflated. However, it is conceivable, as explained with reference to FIGS. 3A-3E, that the tether 213 is detachably connected to the bicycle 1.

The connection of the protective element 21 to the bicycle 1, which is explained in particular with reference to FIGS. 13 and 14, ensures the most stable possible position of the protective element 21 after inflation. In general, such a stable position of the inflated protective element 21 may be e.g. be achieved in that it is connected to the bicycle 1 over as long as possible (for example, front) edge area. For example, the edge region of the protective element 21 is connected to the bicycle 1 via a plurality of attachment points, wherein the outer attachment points have the largest possible distance from each other.

FIG. 15 illustrates that the protective device 2 according to the invention can also have at least two protective elements 21 a, 21 b, which are mounted on different sides of the bicycle 1 and unfold correspondingly on different sides of the container 3. In particular, the protective device 2 according to the invention is designed such that, in the event of a detected imminent fall, both protective elements 21 a, 21 b always deploy. It is also possible that the two protective elements 21 a, 21 b are connected to each other for stabilization, for example via a (not shown in Figure 15) tether. FIGS. 16-18 show further variants of the protective device 2 according to the invention. The protective element 21 of FIG. 16 is similar to the protective element of FIG. 7, but the recess / indentation 214 has a different orientation. According to FIG. 17, the module 20 of the protective device 2 is accommodated in the region of the front trim section 12, in particular adjacent to the steering column. However, the protective element 21 is designed such that after unfolding it has a first (front) section which, via a curvature with a rear, at least immediately after deployment of the protective element 21, is initially substantially parallel to a longitudinal and vertical direction of the bicycle. tion level. About the configuration of the curvature, the protective element 21 can be interpreted to the effect that it realizes the best possible protection for different leg lengths and leg positions.

Figure 18 essentially relates to a modification of Figure 5. Thereafter, the protective element 21, which is mounted analogously to Figure 5 in the region of the seat 1 1 of the bicycle 1, a larger recess / indentation 214, which by intersecting structures in the form of Stegen 2141, 2142 is divided into four segments. The webs 2141, 2142 are e.g. designed as gas-filled channels. Of course it is also possible a different course of the webs (for example in the form of a triangle). Furthermore, only one web could be provided or more than two webs could be provided.

FIGS. 19A, 19B relate to a further variant of the protective device according to the invention. After that, the protective device 2 comprises two protective components 41, 42 which are connected to each other via connecting elements 51, 52 extending laterally from the protective element 21. The connecting elements 51, 52 are designed so that they can be extended along the longitudinal direction of the bicycle 1. In particular, the protection components 41, 42 are connected to each other and fixed with respect to the protection element 21, that after activation of the protection device, the one (rear) protection component 42 moves together with the expanding protection element 21 (FIG. 19B). In particular, the connecting elements 51, 52 are formed from a plurality of mutually hinged struts 51 1, 521, so that the connecting elements 51, 52 can each pull apart like an accordion. It is also conceivable, however, another embodiment of the connecting elements 51, 52, for example using telescopically coupled sub-elements. The protective components 41, 42 and / or the connecting elements 51, 52 are in particular such that they represent an additional protection of the protective element 21 from damage during contact with the roadway. It is conceivable that the protective components 41, 42 are each a part of a cover (eg a module housing) of the protective device 2, wherein the protective components 41, 42 at least partially cover the protective element 21 before inflation.

FIG. 20 indicates that the protective element 21 of the protective device according to the invention can have partial regions 21 1, which have a higher resistance compared to the remaining regions of the protective element 21 (see also FIG. It is conceivable, for example, that the partial regions 21 1 are formed from a different material than the remaining regions of the protective element 21 and / or have a coating. It is also possible that the resistant areas 21 1 have additional material layers. It is also conceivable (FIG. 21) that the entire protective element 21 or at least the outer side, which will come into contact with the road during a fall, is made more resistant to friction with the roadway, for example by using a particularly resistant material , a coating and / or multiple layers of material. FIG. 22 illustrates a bicycle 1 with a protective device according to the invention, which has at least one sensor for detecting an imminent fall. The sensor is, for example, a tilt angle sensor which detects a tilt angle of the bicycle 1, i. an angle φ between a perpendicular to the roadway 100 extending vertical axis V and the height direction H of the two-wheeled vehicle 1, and / or determines a tilting speed. In particular, the sensor (or a control unit connected to the sensor) detects whether the tilt angle exceeds a predetermined maximum tilt angle and / or the tilt speed exceeds a maximum tilt speed. If so, the sensor (or the control unit) generates a signal to trigger the protection device, which upon protection of the signal inflates the protection element 21.

In addition or as an alternative to the tilt angle sensor, the two-wheeler 1 can also comprise a sensor for detecting a contact force K between a part of the two-wheeled vehicle and the roadway 100. point. In particular, the sensor is designed to detect a contact of a lower, lateral subregion 40 of the cladding (for example of the front section 12) of the bicycle 2 or of another lower, lateral structure of the bicycle 2 and possibly a signal to the protective device 2 or initially to to send the already mentioned control unit.

According to FIG. 24, in addition to or as an alternative to the sensor types just described, an optical distance sensor (in particular an infrared distance sensor) can be present, with which a distance d between a structure of the bicycle (in particular the lower lateral portion 40 already mentioned in connection with FIG the fairing of the bicycle 1) and the roadway 100 is measured. If this distance falls below a predefinable minimum value, the sensor or the control unit generates a signal for triggering the protective device according to the invention.

It should be noted that elements of the embodiments described above, of course, can also be used in combination with each other. Thus, e.g. the variants of the protective device of FIGS. 1 to 21 can be realized in each case together with at least one sensor of FIGS. 22 to 24. Moreover, it is possible that the protective device has at least two of the described protective elements 21, which are arranged on different sides of the bicycle. Furthermore, the protective device can of course also be used to protect the seating of larger two-wheelers, in particular for the protection of motor vehicle seats.
