Description

[0001] The invention relates to a gas bag arrangement for vehicle occupant restraint systems according to the preamble of claim 1 and to a steering device according to the preamble of claim 14 containing such a gas bag arrangement.

[0002] Gas bag modules, also known as airbag modules, are usually installed in vehicle steering wheels to protect the vehicle occupants in the event of a collision.

[0003] Due to the rigid coupling between the engine and the steering column, vehicle steering wheels with airbag modules suffer from the problem of vibrations occurring at the steering wheel, at least at certain speeds. These vibrations are caused by the natural frequency of the airbag steering wheel, which is dependent on a specific engine speed. Such vibrations, especially the vibration of the steering wheel rim, are perceived by the driver as undesirable and annoying.

[0004] To prevent such steering wheel vibrations, it has been proposed, among other things, to attach an additional weight mounted on a vibrating mount directly to the steering wheel as a vibration damper. Using the gas generator itself as a vibrating mass is also known. The entire airbag module can also be used as a damping mass, so that the entire airbag module is mounted on a vibrating mount. Such an arrangement, in which the airbag module is connected to the steering wheel in a vibration-decoupled manner, is known from DE 10 2014 015 621 A1. However, the vibrations of the gas generator or the airbag module may be perceptible to the driver under certain circumstances.

[0005] In addition, an arrangement is also known from EP 0 994 793 B1 in which the airbag module is vibration-decoupled from the steering wheel.

[0006] It is also known from JP H06 - 270 817 A that the airbag module is attached to the steering wheel via an elastic damper element.

[0007] DE 10 2007 028 413 A1 describes an airbag module for installation in a steering wheel body, comprising an airbag, an inflation device, and a base plate supporting the inflation device and to which the airbag is attached. The airbag module comprises a housing with a circumferential housing wall on which a cover element is arranged for axial movement. The base plate and the housing are rigidly connected to the steering wheel body.

[0008] The invention is therefore based on the object of keeping the vibrations of gas bag arrangements, which are perceived as disturbing by the motor vehicle driver, as low as possible.

[0009] This object is achieved by a gas bag arrangement for vehicle occupant restraint systems having the features of claim 1 and by a steering device having the features of claim 14.

[0010] A gas bag arrangement for vehicle occupant restraint systems is described, with - an inflatable gas bag to protect a vehicle occupant, - a cover that at least partially covers the gas bag towards the passenger compartment, - a bracket that can be coupled to the cover, - a support plate on which the gas bag and / or a gas generator for inflating the gas bag are arranged and which is connected to the holder, wherein the cover, in its state coupled to the holder, is movable relative to the holder and the support plate is movable relative to the holder, and wherein the cover has a segment with at least one opening and the holder has at least one projection which extends into the corresponding opening of the segment of the cover or which extends through the corresponding opening of the segment of the cover.

[0011] The airbag assembly comprises, in particular, an airbag module, the cover, and the bracket that can be coupled to the cover. The cover is, for example, a cap. For example, the bracket is a retainer of the airbag module and / or the bracket forms, for example, part of a housing.

[0012] The gas bag module comprises at least the gas generator and the gas bag for protecting the vehicle occupant and in particular a carrier, in particular in the form of a carrier plate, which is connected to the gas bag and / or the gas generator.

[0013] The fact that the cover is movable relative to the bracket when coupled to the bracket means, for example, that the cover is movably coupled to the bracket, i.e. although the bracket and the cover are connected to one another, there is a gap between the bracket and the cover, for example, which enables movement of the cover relative to the bracket (at least relative to the rest position of the gas bag arrangement). In particular, the cover is therefore not rigidly connected to the bracket. This allows horizontal and / or vertical movement of the cover relative to the bracket. The cover is therefore mounted so that it can be moved horizontally and / or vertically in relation to the bracket. Mounted so that it can be moved horizontally means that the cover is mounted so that it can be moved perpendicular to the steering axis or at least approximately perpendicular to the steering axis.Approximately perpendicular to the steering axis means that the cover can move at an angle of more than 0° and less than 15°, for example, more than 1° and less than 10° or more than 1° and less than 5°, relative to the steering axis. Vertically movable means that the cover is mounted so it can move parallel to the steering axis.

[0014] The cover can, for example, be mounted so as to be displaceable relative to the holder by at least 0.5 mm or at least 1 mm (in particular horizontally and / or vertically). Thus, the cover can be mounted so as to be displaceable relative to the holder by, for example, 0.5 mm to 4.0 mm, 0.6 mm to 3.0 mm, 0.7 mm to 2.0 mm, 0.8 mm to 1.5 mm, 0.9 mm to 1.2 mm, or 1.0 mm to 1.1 mm. The cover, for example a cap, can be mounted so as to be displaceable by, for example, 1 mm in any direction.

[0015] The gap that may exist between the cover and the bracket, for example, leads to vibration isolation between the cover and the bracket. The cover can therefore be mounted in a vibration-isolated manner from the bracket. However, since the cover can still be connected to the bracket, the entire gas bag assembly or the entire gas bag module can be installed or unlocked very easily.

[0016] In the gas bag arrangement, the cover can be mounted in a floating manner. In particular, the cover can be mounted in a floating manner on the gas bag module, which means that there can be a free space between the cover and the gas bag module or between the cover and the gas bag. In particular, the cover is not firmly connected to the gas bag module. The free space between the gas bag module and the cover or between the gas bag and the cover enables the cover to be moved relative to the gas bag module or the cover to be moved relative to the gas bag. The cover can therefore also be mounted so as to be horizontally and / or vertically displaceable relative to the gas bag module.

[0017] The free space that may exist between the cover and the gas bag module or gas bag itself, for example, leads to vibration isolation between the cover and the gas bag module or gas bag. The cover can therefore be mounted in a vibration-isolated manner from the gas bag module or gas bag.

[0018] The cover can be coupled to the holder. When coupled to the holder, the cover is movable relative to the holder. The at least one segment is understood in particular as a section of the cover that protrudes from the cover in the direction of the holder. The segment can be designed to be radially circumferential or as individual segments that protrude from different positions of the cover into the steering device. The at least one segment can be arranged parallel to the holder or at an angle. In particular, the at least one segment of the cover can be coupled to the holder. The cover, in particular the at least one segment of the cover, can be coupled to the holder, for example via a snap-in connection.

[0019] The connection between the at least one segment of the cover and the holder can be formed either at one or more locations, or the connection can be radially circumferential. The connection can, for example, be a connection that enables movement of the cover, or a segment of the cover, relative to the holder. For example, the connection can be formed from the opening and the projection, with the projection extending into the corresponding opening of the corresponding segment or the projection extending through the opening of the corresponding segment.However, the connection between the segment of the cover and the holder has a certain tolerance (0.1 to 2 mm or 0.5 to 1 mm), so that the projection is, on the one hand, movably mounted in the opening, but on the other hand the end section of the projection engages behind the segment of the cover or the holder to such an extent that it is not possible to detach the projection from the opening.

[0020] The projection may, for example, have a distance of at least 0.5 mm or at least 1 mm from an edge of the opening and / or the end portion of the projection may be at a distance of at least 0.5 mm or at least 1 mm from the segment of the cover.

[0021] The opening in the cover segment can be round or square, for example. The projection of the holder can be designed, for example, in the form of a locking hook or a mushroom-shaped element.

[0022] For example, the at least one projection of the holder can extend through the at least one opening of the cover segment, and the at least one projection can have an end portion that engages behind a portion of the segment. The at least one projection of the holder can extend through the at least one opening of the cover segment, and the at least one projection of the holder can have an end portion that, in the coupled state of the cover and holder, extends at least 0.5 mm or at least 1 mm beyond the cover segment.

[0023] Alternatively, the projection of the holder may be spaced at a distance of at least 0.5 mm or at least 1 mm from an edge of the opening of the segment of the cover.

[0024] For example, the end portion of the projection of the bracket can run obliquely (at an angle greater than 0°) or parallel (at an angle of 0°) to the cover segment. Alternatively, the end portion of the projection of the cover segment can run obliquely (at an angle greater than 0°) or parallel (at an angle of 0°) to the bracket.

[0025] The distances and lengths described in mm refer to the resting state of the airbag assembly. The resting state can be understood as the state of the airbag assembly in which it is not subject to any vibration caused by the vehicle.

[0026] The gas bag module can, for example, be mounted in a swinging manner within the bracket. Within the bracket, at least the gas bag, the gas generator, and the support plate connected to the gas bag and / or the gas generator can be mounted in a swinging manner. The gas generator, the gas bag, and the support plate for the gas bag and / or the gas generator thus swing (in particular invisibly) beneath the cap. The gas bag, the gas generator, a container, and, if applicable, an air bag retaining plate can also be mounted in a swinging manner within the bracket. This has the advantage that the vibration of the gas bag, container, and gas generator is invisible to the vehicle occupant.

[0027] The bracket can be connected to the steering device, for example, either permanently or via a fastening element. The bracket can consist of one or more sections connected to the steering device. Alternatively, the bracket can be attached to the steering device in a radially circumferential manner.

[0028] When coupled to the bracket (when the airbag is not yet inflated), the cover is movable relative to the carrier plate. Since the carrier plate and bracket can oscillate relative to each other when the vehicle is moving, the bracket can be connected to the carrier plate via a vibration damper to dampen the oscillations (vibrations). Vibration dampers are vibration absorbers, i.e., spring-mass systems that dampen oscillations, such as unwanted vibrations from the steering system. The natural frequency of the vibration damper is tuned to the resonance frequency of the respective object to be eliminated. This enables vibration-damped movement of the bracket relative to the carrier plate.

[0029] The properties of the vibration absorber, such as its mass or its material, are tailored to the airbag configuration. For example, the mass of the vibration absorber is tailored to the airbag module in such a way that a phase shift in the airbag module's vibration shifts the natural frequency of the entire system into non-critical ranges. The vibration absorber is made of, or contains, an elastic material (elastomer).

[0030] The gas generator can be attached to the carrier plate by means of a fixing element. The fixing element can be connected to the bracket via a vibration damper. The fixing element can be, for example, a screw including a nut. Alternatively, the fixing element can also be the vibration damper, which can be designed in particular as a damper pin. The damper pin is, for example, made of an elastic material (elastomer) or comprises such a material. The damper pin can thus engage with the bracket on the one hand and with the carrier plate on the other hand, i.e. the damper pin is locked into the bracket and the carrier plate simultaneously. The vibration damper is thus mounted concealed from the passenger compartment.

[0031] Furthermore, a steering device with a gas bag arrangement as described above is described. Thus, a steering device with a gas bag arrangement for vehicle occupant restraint systems is designed, with - an inflatable gas bag to protect a vehicle occupant, - a cover that at least partially covers the gas bag towards the passenger compartment, - a bracket that can be coupled to the cover, - a support plate on which the gas bag and / or a gas generator for inflating the gas bag are arranged and which is connected to the holder, wherein the cover, in its state coupled to the holder, is movable relative to the holder and / or the support plate is movable relative to the holder.

[0032] Thus, a steering device with a gas bag module is described, in which the steering device has a steering device upper side directed towards the vehicle driver, wherein the gas bag module is covered from the passenger compartment by a cover running separately from the steering device on the steering device upper side.

[0033] A steering device can in particular be a steering wheel or a joystick.

[0034] In such a steering device, the bracket can be permanently or detachably connected to the steering device, in particular the steering wheel. The bracket can, for example, be connected to the steering device, in particular the steering wheel, via a fastening element. The bracket can, for example, be connected to the steering device, in particular the steering wheel, using at least one, in particular two, fastening bolts or locking hooks. For example, the two fastening bolts are anchored to a holding element of the steering device, for example a holding plate. This offers the advantage that the gas bag module with the cover and the bracket can be sold or installed as a unit separate from the steering device. This unit (gas bag module) can first be centered and then fastened during installation in the steering device.

[0035] The cover can be mounted on the steering device in a centerable manner. The cover can have a certain amount of play relative to the mount so that the cover, for example a cap, is centered on the steering device, for example the steering wheel, and gap inaccuracies resulting from tolerances can thus be compensated. The cover can thus be centered with the steering wheel during installation in the steering wheel, thereby achieving uniform gap dimensions with the respective adjacent panel or the at least one adjacent control element, in particular a switch.

[0036] In addition, the cover can, for example, be mounted in a vibration-decoupled manner from the gas bag module. For example, the gas bag module can also be mounted in a vibration-decoupled manner from the steering wheel. A steering device is also described, for example, in which the cover is mounted in a floating manner, in particular floating on the gas bag module or the gas bag. The cover therefore has, for example, a gap to the steering device. For example, when coupled to the holder, the cover can have a gap towards the holder. As a result, when coupled to the holder, the cover is movable relative to the holder. In one embodiment, when coupled to the holder, the cover can have a gap towards the holder, towards the gas bag module (or the gas bag) and towards the steering device, in particular towards the steering wheel rim.As a result, the cover, in its state coupled to the bracket, can be movably mounted relative to the bracket, the gas bag module (or the gas bag) and the steering device, in particular the steering wheel rim.

[0037] For example, the gas bag module can be mounted in a swinging (floating) manner within the steering device, wherein in particular the gas bag, the gas generator and the carrier plate which is connected to the gas bag and / or the gas generator can be mounted in a swinging manner.

[0038] The steering device may also include a cover and / or at least one control element. The cover may include multiple parts.

[0039] The cover in particular has at least one segment via which the cover can be coupled to a panel and / or to at least one operating element of a steering device. The cover has, for example, at least one segment that projects into the steering device. The at least one segment of the cover can be coupled to a panel and / or to at least one operating element of the steering device and the holder of the gas bag arrangement. The segment can be designed to run radially all the way around or as individual segments that project into the steering device from various positions of the cover. The at least one segment can be arranged parallel to or at an angle to the steering column of the steering device.

[0040] The cover can be connected to the bracket, for example, using a snap-in connection. This allows the entire gas bag module to be easily installed and released into the steering device.

[0041] The cover can, for example, also be connected to the panel or the operating element, in particular the switch, of the steering device, in particular by means of a connecting element, in particular a locking clip. This makes it possible to anchor it to the panel or the operating element (to the “gap-forming medium”). For example, the segment of the cover can be connected to the panel and / or the at least one operating element of the steering device. In particular, a connecting element, for example a locking clip, can be arranged between the segment of the cover and the panel and / or the at least one operating element. The connecting element is designed such that it allows the cover to be moved towards the panel or the operating element. However, the connecting element can, for example, prevent the cover from moving towards the passenger. The connecting element is designed, for example, as a locking clip.The locking clip is either made of a flexible material or is constructed in a way that allows flexibility, for example to allow lateral movement of the cover.

[0042] In one embodiment, a latching connection can exist between the at least one segment of the cover and the holder, and a latching connection can exist between the at least one segment of the cover and the panel and / or the operating element of the steering device. The at least one segment of the cover can be the same segment. Alternatively, a latching connection can be formed between one segment of the cover and the holder, and a latching connection, for example a latching element, can be formed between another segment of the cover and the panel and / or the at least one operating element. For example, a latching connection can be formed between one segment of the cover and the holder, and a latching element can be arranged between another segment of the cover and the panel and / or the at least one operating element of the steering device.The gas bag and the gas generator can be attached to a container (a carrier plate) that can oscillate within the gas bag module, particularly in a concealed manner. The gas bag package can be held in a desired shape by shaping measures such as a wrap, vacuum technology, or heat folding.

[0043] The invention is explained in more detail below using exemplary embodiments with reference to the figures. They show: Fig. 1 shows a steering device with a gas bag arrangement according to an embodiment of the invention; Fig. 2 a steering device with a non-installed gas bag arrangement according to an embodiment of the invention; Fig. 3 a sectional view of the gas bag arrangement from Fig. 1 with a fixing element and vibration damper; Fig. 4 a sectional view of a modification of the gas bag arrangement from Fig. 1 with damper pin; Fig. 5 another sectional view of a gas bag arrangement from Fig. 1 in which the cover and bracket are coupled via a connecting element; Fig. 6 Design variant of a steering device with a gas bag arrangement installed therein; Fig. 7 a plan view of a cover; and Fig. 8 a schematic representation of the alignment principle from the cover to the steering device.

[0044] In Fig. 1 shows a steering device 14, specifically a steering wheel, of a motor vehicle with an integrated gas bag module 2. The steering device 14 comprises a gas bag arrangement 1 with a gas bag module 2, a cover 3 in the form of a cap, and a holder 4 in the form of a retainer. The gas bag module 2 contains at least one inflatable gas bag 6 for protecting a vehicle occupant, a gas generator 7, and a carrier plate 8 connected to the gas bag 6 and / or the gas generator 7. The holder 4 can be rigidly connected to the steering device 14 or locked to the steering device 14 via a locking connection. The cover 3 covers the gas bag module 2 toward the vehicle owner or the passenger compartment and is coupled to the holder 4. A gap 5 is located between the holder 4 and the cover 3, such that the cover 3, when coupled to the holder 4, is movable relative to the holder 4.The bracket 4 is connected to the support plate 8 via a vibration damper 9.

[0045] In Fig. Figure 2 shows a not yet installed gas bag assembly 1 with the cover 3 and the bracket 4, before it is installed in the steering device 14. The bracket 4, within which the gas bag, the gas generator, and the carrier plate (not shown here) are mounted, has two fastening elements 18, here in the form of fastening bolts, which can each be fastened to a holding element 16 of the steering device 14, for example a holding plate. The cover 3 has at least one segment 31, 32 which projects into the steering device 14. Between the cover 3 and the bracket 4 there is a connection, in particular a snap-in connection, such that the bracket 4 is movably connected to the cover 3. In addition, the cover 3 is fixed to the panel or the operating element 17 by means of a connecting element 15, here in the form of a snap-in clip.

[0046] Fig. 3 shows a sectional view of the gas bag arrangement 1 from Fig. 1, wherein the gas bag module 2, comprising the gas bag 6, the gas generator 7, and the support plate 8, which is connected to the gas bag 6 and / or the gas generator 7, is mounted in a vibrating manner within the holder 4. The gas generator 7 is fastened to the support plate 8 by means of a fixing element 10 in the form of a screw including a nut. A vibration damper 9 is arranged on the fixing element, which dampens the vibrations transmitted by the holder 4 due to the rigid coupling to the steering column, so that the gas bag module 2 is mounted in a vibration-decoupled manner from the holder 4. The cover 3 is also vibration-decoupled or arranged floatingly on the gas bag module 2. The holder 4 is movably coupled to the cover 3, for example by having a gap 5 between the cover 3 and the holder 4. A gap 5 can also be present between the cover 3 and the gas bag 6.The cover 3 has a segment 31 that projects into the steering device 14. The segment 31 of the cover 3 is radially circumferential. At least one opening 13 is located in the segment 31 of the cover 3. The holder 4 has at least one projection 41 that projects into the corresponding opening 13 of the segment 31 of the cover 3.

[0047] A sectional view of the gas bag arrangement 1 with a damper pin 11 is shown in Fig. 4. The gas bag module 2, comprising the gas bag 6, the gas generator 7, and the support plate 8, which is connected to the gas bag 6 and / or the gas generator 7, is mounted so as to be movable (in particular oscillating) relative to the holder 4. The gas generator 7 is fixed to the support plate 8 by means of a damper pin 11. The damper pin 11 simultaneously functions as a fixing element 10 and a vibration damper 9, which dampens the vibrations transmitted by the holder 4 due to the rigid coupling to the steering column. The damper pin 11 is connected on the one hand to the holder 4 and on the other hand to the support plate 8, so that the gas bag module 2 is vibration-decoupled from the holder 4. The cover 3 is also vibration-decoupled or arranged floatingly on the gas bag module 2. The holder 4 is movably coupled to the cover 3. The cover 3 has a segment 31 which is radially circumferential and projects into the steering device 14.The holder 4 is also designed to extend radially all the way around. A connection, in particular a snap-in connection, between the segment 31 of the cover 3 and the holder 4 can be formed either at one or more locations or radially all the way around. The holder 4 has a projection 41 with an end section 411 that extends through the opening 13 of the segment 31 of the cover 3. The end section 411 of the holder 4 is arranged parallel, i.e., at an angle of 0°, to the segment 31 of the cover 3.

[0048] Fig. 5 shows a sectional view of the gas bag arrangement 1, in which the locking connection between the holder 4 and the cover 3 as well as the coupling of the holder 4 to the steering column can be seen. The holder 4 can be connected to the steering device 14. The cover 3 and the holder 4 are coupled via a locking element, for example a locking hook. The holder 4 has a projection 41 with an end section 411 and the cover 3 has a segment 31 with an opening 13. The end section 411 of the projection 41 of the holder 4 projects through the opening 13 of the segment 31 of the cover 3 and engages behind a section of the segment 31 of the cover 3, so that a locking connection is formed.However, this locking connection has a certain tolerance (0.1 to 2 mm), so that the projection 41 is movably mounted in the opening 13, but the end section 411 of the projection engages behind the segment 31 of the cover 3 to such an extent that it is not possible to detach the projection 41 from the opening 13.

[0049] In Fig. 6. shows an airbag arrangement 1 with a cover 3 and bracket 4, which is already installed in the steering device 14. The bracket 4, within which the airbag 6, the gas generator 7, and the carrier plate 8 are mounted, has at least one fastening element 18, which is connected to a holding element 16 of the steering device 14. The gas generator 7 is fastened to the carrier plate 8 by means of a fixing element 10, with a vibration damper 9 being inserted between the bracket 4 and the fixing element 10, which dampens the vibrations transmitted by the bracket 4 due to the rigid coupling to the steering column. The cover 3 has at least two segments 31, 32 that protrude into the steering device 14. A snap-in connection exists between the cover 3 and the bracket 4.Thus, a connection is formed between one segment 31 of the cover 3 and the bracket 4 in such a way that the bracket 4 has a projection 41 that extends through an opening 13 of the segment 31 of the cover 3. As a result, the bracket 4 is movably coupled to the cover 3. Furthermore, another segment 32 of the cover 3, here in the form of a cap, is fixed to the panel or control element 17 of the steering device 14 by means of a connecting element 15, here in the form of a locking clip.

[0050] Fig. 7 shows a top view of a cover 3 of an airbag assembly 1 in a steering device 14. The cover 3 is mounted in a centerable manner within the steering device 14. Centering is enabled, for example, by a centering mechanism, whereby a uniform gap is present between the cover 3 and the panel or an operating element 17 of the steering device 14. The cover 3 is thus mounted in a centerable manner laterally relative to the panel and / or to at least one operating element 17.

[0051] Fig.Figure 8 shows a schematic representation of the alignment principle of the cover 3, in particular the cap, to the steering device, in particular the steering wheel. The cover 3 is mounted in such a way that it can be moved laterally, but prevents movement toward the passenger occupant or away from the passenger occupant in the direction of the steering column. The cover 3 can, for example, move laterally in all directions, in particular toward the panel or control element of the steering device.
