ABSTRACT:
An airbag for automotive vehicles with a gas venting regulation device assembled around a venting opening (11) comprising a first part (15) joined to the inflatable cushion (13) covering the venting opening (11), formed by an elastic area (31) and a non-elastic area (33) with a plurality of openings (17, 19) for the passage of gas; a second rigid part (21) joined to the inflatable cushion (13) and to the first part (15), with a projecting neck (23) forming a gas outlet mouth; and in which at least one part of the non-elastic area (33) is arranged such that when the first part (15) is deformed as a result of the internal pressure in the inflatable cushion during its deployment, the passage of gas through the openings (17) is completely or partially sealed by the projecting neck (23).
