Vehicle airbag inflating system

摘要

The airbag module may be installed in a vehicle. The inflation equipment for the bag includes a hollow profile made of aluminium, which defines a pressure equalising chamber (4). Patterns (11) of holes (12) are pierced in the walls (10) of the chamber. The holes may be elongated slits but circular and triangular apertures may also be used. Horizontal slits of different length may be assembled in patterns like an uppercase letter V or a V with a triangular infill or a circle with or without a circular dot in the centre.
