INFLATABLE OCCUPANT RESTRAINT CUSHION

摘要

A vehicle body includes a steering column mounting a conventional steering wheel having a hub portion and a rim portion joined to the hub portion by spokes. A conventional gas generating device is mounted on the hub portion. An inflatable cushion includes a generally frusto-conically shaped inner wall mounted on the hub around the gas generator and merging into a generally arcuate cross section side wall which merges into the outer wall of the cushion. The outer wall is intended to be engaged by the driver. A tubular porous member extends from the inner wall around the gas generator to the outer wall to provide for diffusion of the generated gas and to also limit the movement of the outer wall with respect to the inner wall to provide in the former a depression of generally shallow concave cross section.
