GAS CUSHION IMPACT PROTECTION DEVICE FOR MOTOR VEHICLES

摘要

In the dish-shaped hub body of a steering wheel between two concentric cylindrical walls and a bottom wall connecting them an annular cavity is formed into which the propellent charge of a gas generator is introduced. This cavity is sealed by an outwardly arched closure plate provided with gas passage openings. An inflatable gas bag in the form of a hose ring is secured with its opening edges to a support plate which is secured at its peripheral edge to the steering wheel body. A separate gas generator housing can be dispensed with.
