Abstract
A pretensioner () for a seat belt system () of an automobile includes a gas generator (), a gas pipe (), a piston () and a coupling mechanism (). 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 () of the seat belt system (). The coupling mechanism is adapted to wind up or pull a seat belt () in accordance with the movement of the piston to increase a restraining force of the seat belt.
