Abstract:
A three-point passive seat belt system includes a continuous-loop restraint belt having upper and lower ends attached to the door. A control belt has its outboard end attached to a junction ring which encircles the continuous-loop belt to define lap belt and shoulder belt portions. The inboard end of the control belt is mounted inboard the seat by a retractor reel which winds the control belt. When the door is closed the retractor winds the control belt to establish the lap and shoulder belt portions respectively across the lower and upper torso of the occupant. The outboard end of the lap belt portion is attached to the door by a resilient anchor strap forward of the MVSS 210 specified mounting location. The limited forward excursion of the lower torso permitted by the combined effects of the forward belt mounting, the yielding and pivoting of the resilient anchor strap under occupant restraint load, and the spool-down of belt on the reel under occupant restraint load cooperates with the simultaneous limited forward excursion of the upper torso to maintain the occupant in a vertically upright or somewhat rearward reclining position to limit the forward rotational excursion of the head.
