Abstract

An automobile steering wheel that is disposed below a plane of a steering wheel rim. As a protection against impact, there is a plastically deformable cup-like deformation member within the steering wheel that absorbs energy due to an impact of a driver of the motor vehicle on the steering wheel. Spokes are constructed in such a manner that the contribute to the energy absorption by a performance of deformation work. The deformation member has a height which is less than a distance between the hub and the plane of the steering wheel rim. The deformation member is fixedly connected in its upper region with the respective spokes.
