摘要
An airbag 10 includes a panel 14 and a plurality of fingers 16. The panel includes an impact surface 18 and defines an inflation chamber (20, figure 6A) inflatable to an inflated state. The plurality of fingers are in communication with the inflation chamber. Each of the fingers are spaced from each other and extend from the impact surface away from the inflation chamber in the inflated state. The panel may have an axis C about which the fingers are spaced, and where the length of the fingers may increase the further they are spaced from the axis. The chamber may comprise inner and outer chambers (50, 52) separated by a diaphragm (48) provided with a vent (56). Also disclosed is a vehicle safety system comprising an airbag with fingers, provided on a reaction surface of the vehicle. During a vehicle impact, the momentum of the occupant may move the occupant towards the plurality of fingers. The fingers may absorb energy from the occupant and reduce or prevent the head of the occupant from sliding across the impact surface and/or rotating.
