Restraint systems (Description): Description and operation

DESCRIPTION

The airbag Supplementary Restraint System (SRS) is a safety device which, when deployed in the event of a severe frontal impact, provides additional protection to the driver’s face and upper torso. The airbag is designed to inflate when the vehicle is exceeding a set speed and receives a frontal impact within the area shaded.

The pretensioner consists of the seat belt buckle and stalk, and a spring driven pretensioning mechanism. The pretensioners, fitted to both driver and passenger seat belt mechanisms are designed to remove any play in the the lap and diagonal belts in the event of a severe frontal impact.
