Abstract

See full text

A one-piece woven pressure-responsive air outlet, for use as a vent, for application to airbag discharge openings, includes a lower fabric layer, a middle fabric layer and an upper fabric layer. The lower fabric layer includes warp and weft threads and an inflow region in which the warp and weft threads float. The middle fabric layer includes warp and weft threads and a flow-through region in which the warp and weft threads float. The lower and middle fabric layers include a first chamber and a second chamber downstream of the first chamber in a flow direction. At least one of the chambers is sealed with a thread breakage zone, in which between the fabric layers, selected (warp) threads of one fabric layer are merely tacked to selected (weft) threads of the other fabric layer and are capable of breaking or rupturing at a predefined internal pressure in the chamber.
