ABSTRACT:
A steering wheel unit for a motor vehicle, in particular a passenger car, comprises a connection hub which may be non-rotatably connected with a steering shaft of a steering device, a steering wheel rim which is non-rotatably connected with the connection hub by spokes, and a central piece which is mounted by a spacer element to the connection hub so as to be rotatable relative to the steering shaft and the steering wheel rim. The steering wheel unit further comprises a coupling device which arrests the central piece with respect to a rotational movement of the steering wheel rim. The spacer element has a first end which is non-rotatably connected with the central piece, and has a second other end which is rotatably mounted to the connection hub and constructed as a crash element. The crash element fails after a predetermined failure value of a force driving the central piece towards the connection hub. The steering wheel rim is supported by its spokes on the central piece at least in a direction leading from the steering wheel rim to the connection hub and the spokes are rotatably mounted on the central piece in a region of the support.
