<p>A pretensioner (1) for a seat belt system (7) of an automobile comprises a gas generator (2), a gas pipe (3), a piston (5) and a coupling mechanism (6). The gas generator (2) 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 (3) is formed to receive therein the gas generator (2). The gas pipe (3) is adapted to guide the high-pressure gas released from the gas generator (2) to the piston (5). The piston (5) is adapted to be moved or displaced by a pressure of the high-pressure gas guided by the gas pipe (3). The coupling mechanism (6) is connected to each of the piston (5) and a buckle (8) of the seat belt system (7). The coupling mechanism (6) is adapted to wind up or pull a seat belt (9) in accordance with the movement of the piston (5) to increase a restraining force of the seat belt (9).</p> |
