The supplemental restraint system consists of SRS air bag and seat belt with pre-tensioner and force limiter systems.

The pre-tensioner system will retract their respective belts instanously, reduce injury from excessive movement, thus maximizing the seat belt’s effectiveness if there is an impact severe enough to injure the driver and the passenger. And each force-limiter system will effectively absorb the load applied to the seat belt so as to minimize the impact to the passenger. When the impact sensors detect an impact of sufficient force, the air bag control unit will activate the automated circuit to ignite materials in the inflators (in the air bag modules and seatbelt pre-tensioners) to generate gas and inflate the air bags.

(1) SRS-Air bag

The air bags are designed to deploy when the vehicle suffers a sufficient impact to protect human from injury.

(2) Force limitter

To reduce excessive force application on passenger by the seatbelt

(3) Pretensioner

To limit a movement of passenger forward by pulling the seatbelt
