Abstract: An auxiliary anchorage for a shoulder belt is comprised of an anchor ring which is mounted on a structural member of the vehicle body by an anchor belt which passes through an opening in the seat back cushion. The anchor ring is C-shaped and has an entry opening smaller than the width of the shoulder belt. The shoulder belt is removably inserted into the opening in the C-shaped ring. As the belt unfolds the belt obstructs the opening of the C-shaped ring. The C-shaped ring is mounted at a height lower than the shoulder belt retractor so that the C-shaped ring effectively lowers the height of the shoulder belt anchorage whereby the shoulder belt dwells at an adjusted angle of repose. The anchor belt may be stiffened by a plastic sheath so that the C-shaped ring is held at a readily accessible presence relative the opening in the seat back cushion and may be swung into a stored position in the opening in readiness for subsequent withdrawal from the opening to enable the insertion of the shoulder belt therein.
