Air bag mounting system for motor vehicles

摘要

A steering wheel for a vehicle comprises an outer wheel member, a boss plate arranged in a central hollow space of the wheel member, and a plurality of spoke members connecting the wheel member and the boss plate. The steering wheel is designed for having light weight and high rigidity and for mounting an air bag unit thereon. The spoke members are integrally formed with the boss plate at their inner ends. The boss plate and the spoke members are provided with continuous flange portions along their edges. The boss plate is further provided with side flanges each disposed between base portions of a pair of adjoining spoke members and each extending along one lateral edge of the boss plate. Each of the side flanges has a width larger than that of the other flanges and bent behind the major plane of the boss plate with an angle, preferably a half of the right angle, with respect to the major plane of the boss plate, to constitute means for securing air bag unit.
