When a vehicle has crashed with a certain degree of frontal impact, the gas generator is made to ignite by the electrical firing signal from SRSCM.Gas from the gas generator causes movement of the piston in the manifold case (cylinder), which operates a rack gear.

Therefore the seat belt pretensioner helps to reduce the severity of injury tot he front occupant by retracting the seat belt webbing to prevent the occupant from moving forward and hitting the steering wheel or instrument panel when the vehicle is crashed.
