Movement limiting band for an airbag module

Abstract

Elongate woven pulling means (10) for an airbag module comprises plural longitudinal portions (12, 14, 16, 18, 20) that have different warp densities. An airbag module for a vehicle safety system comprises an airbag, pulling means (10) coupled to the airbag and an activation unit coupled to the pulling means for releasing the pulling means upon actuation of the activation unit. The pulling means (10) is an elongate woven pulling means having different warp densities which is fastened to the airbag by a first end portion (12) of low warp density, preferably by stitching, and is coupled to the activation unit by a longitudinal portion (16) of high warp density. A method of manufacturing such pulling means (10) comprises the steps of: weaving a longitudinal portion (12; 20) on a loom of low warp density; and weaving a further longitudinal portion (16; 14, 18) on the loom having high or increasing warp density in the same working step. For weaving an adjustable reed having different widths is employed.
