A first slip joint and a second slip joint are respectively arranged on a member mounted within an upper part of a car and a member mounted within a lower part of a car, a retractor is mounted on a side wall inside the car body (upon, for example, a center pillar) between the first and second slip joints, and a shoulder belt and a lap belt are respectively conducted from the retractor to a tongue plate through the first slip joint and through the second slip joint. A load which is exerted on a mounting portion of the retractor when the car body is suddenly decelerated can be confined to below approximately 50 Kg.

Seat belt system

An impact energy absorbing apparatus having two cylinders coupled for telescopic movement under impact axially applied thereto. In addition to rigid balls press-fitted between the cylinders, the apparatus has idle rigid balls snugly fitted therebetween which are to be conducted for rolling movement along respective guide grooves of certain length formed on the cylinder. The characteristic of load-stroke relationship is thereby improved to provide optimum efficiency of impact absorption.
