Seat belt pretensioner
When the vehicle is involved in an accident at a certain angle with respect to the frontal impact, the gas generator is ignited by a signal from the SRSCM.
The gas escaping from the gas generator will cause the piston to move in the pretensioner gear cylinder.
The gear train rotates the piston gear and the planetary gear rotates the planetary gears.
As a result, the belt is tensioned due to the rotation of the drum. Therefore, a pretensioner belt reduces the severity of injury to the driver and front passenger by pretensioning the belt. This prevents the driver and front passenger from moving forward and avoids hitting the steering wheel or instrument panel.
Seat belt load limiter
The load limiter is designed to reduce the impact force of the driver and front passenger on the fastened seat belts during a collision. If the collision force reaches a certain value, the torsion bar of the pretensioned seat belts deforms and releases the seat belt slightly, reducing the force of the impact.
Withdrawal
1. Disconnect a wire from the negative plug of the storage battery.
Warning! Before servicing the airbag system, make sure that at least 30 seconds have passed after the ignition is turned off and the wire is disconnected from the negative terminal of the battery.
2. Turn out screws of fastening of an overlay of a threshold.
3. Turn out a bolt of the bottom fastening of a forward seat belt and a blade of a flat screw-driver lift up and remove an upholstery of an average rack.
4. Turn out a bolt of the top fastening of a forward seat belt.
5. Turn out a bolt of fastening of a natyazhitel of a forward seat belt and remove a belt from the car.
