Abstract: An occupant restraint system includes an airbag and an inflator. The front end of a gas supply pipe, which extends from the inflator housed in a rear pillar to the interior of the airbag and guides the gas generated by the inflator to the airbag, is substantially vertically aligned with front portion of a rear wheel wheelhouse of the vehicle. Since the gas supply pipe can be positioned in an area in which the vehicle body rigidity has been increased by the rear pillar and the wheelhouse, it can be effectively prevented from being damaged due to the impact of a side collision of the vehicle. Moreover, since the inflator is housed in the rear pillar, which is wider and more rigid than a front pillar, it is possible to minimize or effectively prevent damage to the inflator.

Abstract: A vehicular occupant restraint system is provided with an airbag and an inflator. A front end of the folded airbag is housed within a front pillar garnish covering a side face on the occupant compartment side of a front pillar, and impact absorbing ribs are formed on the inner face of the front pillar garnish only in a section(s) that receives little deformation when the airbag is deployed. Since the front pillar garnish can be easily flexed when the air bag is deployed, there is neither inhibition to the smooth deployment of the airbag nor splitting and scattering of a part of the front pillar garnish. Moreover, since the impact absorbing ribs are formed on the front pillar garnish in the section(s) that receives little deformation, the impact of a secondary collision to an occupant can be absorbed effectively by the impact absorbing ribs.
