Occupant restraint system
First Claim
1. An occupant restraining system for a vehicle, in which an airbag including a plurality of cells branching downward from a gas distribution path extending along an upper rim of a base cloth is folded and disposed on a side of a roof, gas generated by an inflator upon a vehicle collision is supplied to the cells through the gas distribution path, and the airbag is inflated and deployed into a shape of curtain along an inner surface of a side of a vehicle compartment,wherein at least two adjacent ones of the cells inflated along an inner surface of a pillar have axes thereof extending parallel with each other, said adjacent ones of the cells each comprising an upper portion which extends from the gas distribution path downwardly in a vertical direction, and a lower portion which extends from the upper portion in a direction inclined with respect to both of an extension direction of the pillar and the vertical direction, said extension direction being the direction of an axis of the pillar in a region from the roof to a bottom of a window adjacent to the pillar, said at least two adjacent ones of the cells having lower ends ending at a lower end of the curtain.

Abstract
In an occupant restraint system C, an airbag 21 is inflated by using gas, which is generated by an inflator 35 upon a vehicle collision, to be deployed into a shape of curtain along the inner surface of a side of a vehicle compartment. The occupant restraint system C includes pluralities of cells 21c and 21d, which are inflated along the inner surfaces of a B-pillar 15 and a C-pillar 16. By inclining axes S1 to S4 of the cells 21c and 21d with respect to an axis P1 of the B-pillar 15 or an axis P2 of the C-pillar 16, the lower ends of these cells 21c and 21d are hardly trapped by the B-pillar 15 or the C-pillar 16. Thus, the cells of the airbag are prevented from being trapped by the pillars to thereby enable the smooth deployment of the airbag.

wherein at least two adjacent ones of the cells inflated along an inner surface of a pillar have axes thereof extending parallel with each other, said adjacent ones of the cells each comprising an upper portion which extends from the gas distribution path downwardly in a vertical direction, and a lower portion which extends from the upper portion in a direction inclined with respect to both of an extension direction of the pillar and the vertical direction, said extension direction being the direction of an axis of the pillar in a region from the roof to a bottom of a window adjacent to the pillar, said at least two adjacent ones of the cells having lower ends ending at a lower end of the curtain.
