Abstract

Abstract A gas bag for a vehicle has an substantially elongated shape and is convertable from a folded-up condition to an inflated condition. The vehicle has securing sites between which the bas bag is installed bow-shaped. The gas bag has an outer wall, two opposed longitudial ends and at least one element, the element constricting the gas bag in its inflated condition substantially transversely to the longitudinal direction of the gas bag so that the gas bag is shortened in the longitudinal direction and bridges the securing sites by the shortest way.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 119 words
A gas bag for a vehicle, said gas bag having a substantially elongated shape and being convertible from a folded-up condition to an inflated condition, said vehicle having securing sites between which said gas bag is installed bow-shaped, said gas bag including an outer wall, two opposed longitudinal ends and at least one element, said element constricting said gas bag in its inflated condition substantially transversely to the longitudinal direction of said gas bag so that said gas bag is shortened in said longitudinal direction and bridges said securing sites by the shortest way, wherein said element constricts at least the lower edge portion of said gas bag in its inflated state so that the lower edge is curved.
