ABSTRACT:
A vehicle side impact restraint system especially adapted for providing head impact protection. The system employs a deployable restraint curtain which is maintained stowed in an undeployed condition within a slot along the upper edge of a vehicle side door window. A track assembly is vertically mounted along the rear edge of the window and includes a gas generator, a track, and a sliding projectile. The upper edge of the triangularly shaped curtain is attached to the vehicle whereas the rear end of the lower edge is mounted to the projectile. Upon deployment, the sliding projectile pulls the curtain to a downward position in response to a deployment signal sent to the gas generator. The projectile reaches the lower end of the track where it is locked in position thus stretching the curtain across a portion of the window area, thus providing a surface for impact energy absorption.
