Abstract
Airbag module, in particular disposed in the vehicle seat as an anti-submarining airbag module, comprising an inflator or a connection therefor, a tubular airbag, the two free ends of which are folded over at least once transversely relative to the longitudinal direction of the airbag to form loops, and wherein introducible into the loops of the airbag is a clamping member, by means of which the two layers of the folded-over parts of the airbag are brought into contact, to seal the airbag at least partially in a gastight manner.
Claims16
Airbag module, in particular disposed in a vehicle seat as an anti-submarining airbag module, comprising
- an inflator or a connection therefor,
- a tubular airbag, the two free ends of which are folded over at least once transversely relative to the longitudinal direction of the airbag to form loops, and
- wherein introducible into the loops of the airbag is a clamping member, by means of which the two layers of the folded-over parts of the airbag are brought into contact to seal the airbag at least partially in a gastight manner.
Airbag module according to one of the preceding claims, wherein the airbag in an inflated state presses against the clamping member so that the two layers of the airbag in the region of the folded-over parts are pressed to a greater extent against one another.
Airbag module according to one of the preceding claims, wherein the clamping member is connected by a means for fastening, preferably screws, rivets or bolts, to a frame part of a vehicle.
Airbag module according to one of the preceding claims, wherein the clamping member at at least one side of the airbag extends beyond the airbag.
Airbag module according to one of the preceding claims, wherein the clamping member has a rod shape.
Airbag module according to one of the preceding claims, wherein the ends of the folded-over parts are connected by a suitable fixing means, such as for example stitching, gluing or welding, to the airbag.
Airbag module according to one of the preceding claims, wherein the inflator is disposed inside the airbag.
Airbag for an airbag module, wherein the airbag is formed from a portion of a seamless continuous tube and/or of seamless tubular meter goods, the free ends of which, to form loops, are folded over at least once transversely relative to its longitudinal direction and fixed to a part of the airbag.
