System for positioning the shoulder belts of a safety belt in longitudinal direction of the legs of a U-shaped yoke

摘要

Arrangement for positioning the length-adjustable shoulder straps (12) of a seatbelt in the longitudinal direction of arms (5) provided with friction-increasing surfaces (17) of a rigid U-shaped shoulder harness for the upper body of a vehicle occupant comprises structures (S) allowing relative displacement of the shoulder straps to the arms in their longitudinal directions on an increase in friction and preventing transverse displacement.
