Abstract
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.
