ABSTRACT:
A safety steering wheel having an impact protector mounted on the hub of the steering wheel and which consists of a collapsed gas bag and a housing which contains a propellant for inflating the gas bag. The impact protector is covered by a cover hood, which is made of soft elastic plastic and reinforced by a reinforcing layer. In order to prevent a bulging of the cover hood by the forces which are exerted by the collapsed gas bag, a frame is provided, which is secured to the carrier for the housing which contains the propellant. The frame surrounds the housing and the gas bag and comprises at least one retaining member, which is integrally joined to the frame and attached to that edge of the frame which faces the driver's compartment. The retaining member when in a rest position extends in front of the collapsed gas bag and in the case of an impact is adapted to be bent up toward the driver's compartment along a straight line. A reinforcing layer is provided, which is made of hard plastic and covers the gas bag, wherein the rated breaking line of the cover hood that is connected to the frame and extends along those sides of the reinforcing layer which are not directly connected to the retaining member.
