摘要： The invention relates to an airbag module (10) for a vehicle steering wheel (6), comprising a module base (12) for fixed mounting on the vehicle steering wheel (6), which module base has a base opening (14), and a vibration absorber ring (16) for fastening a gas generator (18) to the module base (12) such that said gas generator can vibrate. The vibration absorber ring (16) has a ring axis (A) and a mounting flange (20) for the gas generator (18). The vibration absorber ring (16) has a resilient absorber wall (22), starting from the mounting flange (20), which absorber wall extends in an axial direction toward the module base (12) and extends around the ring axis (A) in the circumferential direction. The vibration absorber ring (16) has a plurality of resilient absorber feet (24) for fastening to the module base (12), which absorber feet extend in the axial direction. The vibration absorber ring (16) is fastened to the module base (12) by means of the absorber feet (24) such that the absorber wall (22) bears against the module base (12) already before activation of the airbag module (10) and acts in an axial direction against the module base (12) and is resiliently deformed.

摘要： The disclosure relates to a coupling device for securing an airbag module to a steering wheel main body of a vehicle steering wheel. The coupling device comprises: a securing body which has, relative to a steering wheel axis, an axial lower face that faces the steering wheel main body when the vehicle steering wheel is assembled, and an axial upper face that faces the airbag module when the vehicle steering wheel is assembled. An engagement element is disposed on the upper face of the securing body, for engaging with the airbag module. The engagement element is designed so that the airbag module can be coupled to the securing body by an engagement connection in such a manner that it cannot be substantially axially displaced or it can be limitedly axially displaced. An electronic control unit is provided and the securing body at least partly forms a housing of the electronic control unit.

摘要： The invention relates to an airbag (14) for unfolding between a vehicle part (10) and a vehicle occupant (18), comprising an impact wall (20) which, in the installed and unfolded state of the airbag (14), faces a vehicle occupant (18) and a circumferential wall (22) which is connected to the impact wall (20) and, in the installed and unfolded state of the airbag (14), extends between the impact wall (20) and the vehicle part (10), wherein the circumferential wall (22) is made with multiple layers, at least in some sections, and forms at least one annular tube (23) which delimits an annular inflatable first airbag volume (V1), and wherein a radially inner layer (26) of the circumferential wall (22), together with the impact wall (20), delimits an inflatable second airbag volume (V2) that is separate from the first airbag volume (V1). The invention further relates to an airbag module (12) having such an airbag (14).

摘要： A method for detecting contact with a manually activated steering or control device, in particular a vehicle steering wheel, comprises the following steps: applying an alternating voltage to at least one conductor arrangement (10) which is arranged on the steering or control device, and has at least one conductor line with a significant ohmic resistance; determining the current profile in the conductor arrangement (10); determining the real component and the virtual component of the instantaneous alternating current resistance of the conductor arrangement (10); determining the capacitance or the change in capacitance of the conductor arrangement (10); determining the phase shift; and evaluating the determined values. A device for carrying out the method comprises a steering or control device, in particular a vehicle steering wheel, a conductor arrangement (10) which is arranged on the steering or control device and which has at least one conductor line with a significant ohmic resistance, and a control and evaluation device which is configured to apply an alternating voltage to the conductor arrangement (10), to measure the current profile in the conductor arrangement (10) and to evaluate the determined values.

摘要： A steering apparatus assembly, having a steering axis, about which the steering apparatus assembly can rotate in is disclosed. The steering apparatus assembly comprises a first element and a second element. The two elements are connected to one another by a first and second joints. The first joint comprises a resilient locking element, which is deflectable in a direction transverse to the steering axis to disengage the first joint. The second joint is deflectable by an axial load acting on the assembly elements away from one another. A wedge is provided having a wedge length transverse to the steering axis and a variable wedge height in the direction of the steering axis. The wedge length and length and a wedge inclination angle are matched to one another such that both the first joint and the second joint can be undone by a linear movement of the wedge in the longitudinal direction.

摘要： A steering apparatus assembly for a motor vehicle, having a steering axis, about which the steering apparatus assembly can rotate in the installed condition is disclosed. The steering apparatus assembly comprises a first assembly element and a second assembly element. The two assembly elements are connected to one another by a first joint and a second joint. The first joint comprises a resilient locking element, which can be deflected in a direction transverse to the steering axis to disengage the first joint. The second joint can be disengaged by an axial load acting on the assembly elements away from one another. A wedge is provided which has a wedge length transverse to the steering axis and a variable wedge height in the direction of the steering axis. The wedge length, the wedge height and an angle of inclination of the wedge are matched to one another such that both the first joint and the second joint of the assembly elements can be undone by a linear movement of the wedge in the longitudinal direction of the wedge.
