  • Patent number: 5655789
    Abstract: In a gas bag collision safety system for the steering wheel of street vehicles, the bowl-shaped steering wheel, into which a gas bag is folded, is fastened to the hub of the steering wheel, and the marginal area defining the gas inlet of the gas bag is joined gas-tight to the steering wheel hub. An improvement in installation accuracy is brought about by the fact that the gas inlet opening of the gas bag is made concentric with a through-bore made in the steering wheel hub and the gas generator is contained in the steering spindle.
