  • Steering wheel having a steering wheel hollow
    Patent number: 6312011
    Abstract: A steering wheel is fastened on a steering column by a steering wheel hollow (1). Within this steering wheel hollow (1), an airbag (15) is fastened on a plate (11) which in the rest position bears against the base (2) of the steering wheel hollow (1) and, as the airbag (15) inflates, the plate is displaced within the steering wheel hollow (1) away from the base (2). The steering wheel has travel limitation members (screw 12) for the maximum possible travel of the plate (11). Release of the airbag (15) produces a free space (16) between the plate (11) and the base (2) of the steering wheel hollow (1), which free space is formed so as to receive end regions of spokes (4, 5), which end regions are remote from a steering wheel rim (6).
