Abstract: A pretensioner (1) for a seat belt system (7) of an automobile includes a gas generator (2), a gas pipe (3), a piston (5) and a coupling mechanism (6). The gas generator is adapted to generate a high-pressure gas when a shock occurs in the automobile due to a collision, a sudden stop, etc. The gas pipe is formed to receive therein the gas generator. The gas pipe is adapted to guide the high-pressure gas released from the gas generator to the piston. The piston is adapted to be moved or displaced by the pressure of the high-pressure gas guided by the gas pipe. The coupling mechanism is connected to each of the piston and a buckle (8) of the seat belt system (7). The coupling mechanism is adapted to wind up or pull a seat belt (9) in accordance with the movement of the piston to increase a restraining force of the seat belt.

Abstract: An air-bag arrangement includes an air-bag and a gas generator to supply gas to inflate the air-bag. The gas generator is hingedly connected to a support and is hingedly movable between a closed position in which the gas generator extends across and closes an aperture, and a second position in which the apertured is opened to permit the flow of gas from the air-bag. The gas generator is initially retained in position by a retainer the retainer being actuable, in response to a signal, to enable the gas generator to move hingedly to the open position.
Abstract: An igniter composition for a gas generant and related methods of gas generation are provided in which the igniter composition desirably avoids or is not prone to being ignited by thermal means at ambient pressure conditions.
