Supplemental Restraint Systems

Introduction

Supplemental Restraint Systems (SRSs) are also called airbag systems. An airbag is a balloon-type passenger safety device that inflates automatically on vehicle impact. Original systems were designed to protect only the driver. In addition, the airbags inflated only if there was sufficient impact at the front of the vehicle. Modern systems also protect the passengers. They can be triggered by side as well as frontal impacts. Airbag systems are intended to be used with seat belt restraints. An unbelted driver or passenger is not likely to receive maximum protection for the airbag. Unbelted occupants have been seriously injured or killed by inflating bags.
