Seat Belt Tensioner and Driver's Seat Belt Outer Lap Tensioner
The seat belt tensioner and the driver's seat belt outer lap tensioner instantaneously retract the seat belt at the time of a collision and the effect of the seat belt is increased further by securely restraining the occupant in the seat. In the case of a low to medium speed or high speed collision, the airbags, the seat belt tensioner, and the driver's seat belt outer lap tensioner are activated to secure the restraining effect of the occupant and the safety performance. In the case of a low-speed collision, the seat belt tensioner and the driver's seat belt outer lap tensioner operate together because occupant restraint can be secured by the seat belt only.
