Various implementations of a horn system include one or more force sensors disposed on a first portion of a driver air bag module and one or more actuators disposed on a second portion of the driver air bag module. For example, the force sensors may be disposed adjacent a perimeter of a base plate of the driver air bag module, and the actuators may extend inwardly toward the force sensors from an inner surface of a cover of the driver air bag module, or vice versa. To actuate the horn, the cover is moved axially toward the base plate, causing the actuators to apply force to the force sensors. Force signals received from the force sensors are used by one or more processors to determine characteristics of the force received and/or select a control message for communicating to the horn system based on the force signal characteristics.

A steering wheel includes a steering wheel body, an airbag module, and a damper unit-4 that connects the steering wheel body and the airbag module-3. The airbag module is mounted to the steering wheel body via the damper unit facing in a Z-axis first direction that is an example of a first direction. The damper unit-4 is configured to apply a force on the airbag module in a state where the airbag module is mounted on the steering wheel body in a direction of pushing up the airbag module in a direction that intersects with the Z-axis first direction.

A damper assembly configured to mount an airbag module to a steering wheel including a steering wheel armature includes a damper element configured to engage the steering wheel armature and to extend through an opening in the steering wheel armature.

One of the hub assembly or the airbag module includes one or more alignment portions structured to align each fastener opening in the hub assembly attachment tabs with a respective fastener opening in one of the airbag module attachment tabs when the temporary fasteners of the hub assembly or the airbag module are coupled to the portion of the other of the hub assembly or the airbag module.

The disclosure is directed to a steering device assembly for positioning and fastening an airbag module on a steering device of a motor vehicle. The steering device assembly comprises a first positioning body having a detent lever, a carrier, a spring element, and a second positioning body. The detent lever comprises a first leg and a second leg connected to the first leg at one leg end the detent lever is mounted for pivoting between an initial position and a final assembly position on the carrier. The spring element loads the detent lever into the final assembly position. Each leg extends to an opposite free leg end at a specified angle. The second positioning body has a stop for the free leg end of the first leg for pivoting the detent lever from the initial position into the final assembly position and a detent contour for locking with the free leg end of the second leg in the final assembly position of the detent lever. A method for installing an airbag module on a steering device of a motor vehicle by the steering device assembly.

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.
