An airbag for a vehicle occupant protective system comprises an inflatable cushion, a cinch tube circumventing a vent aperture disposed in the cushion, and a draw element guided in a circumventing channel of said cinch tube and being coupled to a surface of said cushion such that deployment of said cushion causes said draw element to contract said cinch tube. The airbag comprises a contraction limiting arrangement adapted to limit the contraction of said cinch tube by said draw element to a predetermined minimum free diameter d of at least 20% relative to the free diameter D of the open cinch tube.

Airbag for a vehicle occupant protective system

A safety airbag arrangement for a vehicle comprises a main airbag having an inlet for connection with an inflator and a gas deflector bag secured within the main airbag, having an inlet in register with the inlet of the main airbag, for connection with the inflator, the gas deflector bag having ventilator holes and the arrangement being such that gas supplied to the airbag arrangement via the inlets by the inflator must first pass into the gas deflector bag, to pass subsequently from the gas deflector bag through the ventilation holes. The wall of the gas deflector bag is secured to the main wall of the main airbag by a plurality of arcuate seams spaced progressively from inlets, to maintain the gas deflector bag in a predetermined position relative to the main airbag when the airbag arrangement is activated.
