Restraints and Safety Systems: Description and Operation

Airbag Diagnostic Unit (ADU):

AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The Air Bag-Supplemental Restraint System (SRS) is designed to supplement driver and passenger seat belts during front-end collisions, reducing the risk of serious injury or death. Two collision-sensitive sensors are located in the Air Bag Diagnostic Unit (ADU). When a frontal collision of sufficient force occurs, the senses it causing ignition in each of the air bags. The driver is protected by a Steering Wheel mounted Air Bag, and, a Knee Air Bag, located behind the driver's knee bolster, and also, the passenger is protected by a passenger air bag, located on instrument panel.

The Knee Air Bag works in conjunction with the driver's seat belt to maintain their correct position in relation to the Steering Wheel mounted Air Bag in the event of a frontal collision. By absorbing the impact of the legs, the Knee Air Bag reduces the "submarine" effect which typically occurs in a frontal collision. By minimizing this effect, the Knee Air Bag causes the upper body to contact a larger surface area of the Steering Wheel Air Bag and at an improved angle which dramatically reduces the force transferred to the head and chest areas during a front collision. Although smaller than the Steering Wheel mounted Air Bag, the Knee Air Bag is attached directly to the Knee Bolster Panel which remains intact to provide a wider and flatter surface which is much better suited for contacting the legs of the driver.

Seat Belt System:

SEAT BELT SYSTEM
The seat belt system consists of five restraints. The outboard passengers (front and rear) have both shoulder and lap seat belts. The inboard passenger (rear) has only a lap seat belt. The driver's seat belt is equipped with a warning lamp on the dash and an audible chime to remind the driver to fasten the seat belt. The warning ceases after approximately 60 seconds. There are no warnings on the other passengers' belts. The retractors are securely mounted to the body. The buckles are also securely mounted to the floor.
