Abstract

An automotive seat belt has seat tightening mechanism associated with the strap end-fixture. The tightening mechanism is operated by a pyrotechnic contracting muscle (16) fixed to the vehicle structure and coupled to the seat buckle (28). The second end of the pneumatic strap is anchored to a wire (26).
