• a self-adjusting webbing guide (65);
• a vertical strap webbing (55) extending from a lower portion located inside or behind a seat back (2) extending upwardly to an intermediate location passing through a passageway or slot (84) in the seat back (2) and extending against the seat back (2) passing through the webbing guide (65) to an upper anchorage (41);
• wherein the seat belt retractor (40) is located inside or behind the seat back (2) at a location at least 450 mm above the vehicle seat and wherein the shoulder webbing (25) passes through an upper opening (82) in the seat back (2) to connect to the retractor (40);
• wherein the self-adjusting webbing guide (65) includes a pivoting guide (66) connected to a locking mechanism (70) activated by a forward movement of the occupant extending the shoulder webbing (25), the shoulder webbing (25) being passed through an opening in the pivoting guide (65) and free to move relative to the pivoting guide (66);
• wherein the locking mechanism (70) is activated by the shoulder webbing (25) pulling on the pivoting guide (66);
• wherein the vertical strap webbing (55) passes through the locking mechanism (70) of the self-adjusting webbing guide (65);
• wherein the locking mechanism (70) further has a rotatable wedge (72) for gripping the vertical strap webbing (55) upon locking;
• wherein the rotatable wedge (72) has a plurality of serrated teeth or edges (77) for gripping the vertical strap webbing (55) upon activation;
• wherein the vertical strap webbing (55) at a lower end is attached to a shock absorbing spring (80), the shock absorbing spring (80) being attached to the seat frame (2);
• wherein the shock absorbing spring (80) has a length (1) in an unstretched condition
• wherein the shock absorbing spring (80) stretches when the forward movement of the shoulder webbing (25) moves the guide mechanism (65) to a locking angle,
• wherein the shock absorbing spring (80) is a coil spring made from wound wire of a length (x)
• wherein the coil spring (80) stretches increasing the length (1) to maximum length of the wound wire (x) or less.
