* The pretensioner picks up the collision signal
* The electrical pulse is released and transmitted to the gas igniter, which detonates the ignition agent inside the tube inflator.
* The steel ball moves forward in the pipe, driving the spiny gourd to rotate.
* The pawl disc is integrated with the shaft, and the seat belt is wound on the shaft.
Simply put, it is the air pressure that makes the ball chain move in the tube inflator, the ball drives the pawl disc to rotate, and the pawl disc drives the shaft to rotate to achieve the ideal seat belt pretensioning function. The end of the tube is the cavity that accommodates the movement of the steel ball chain.
