Abstract
The present invention provides a seat belt apparatus having a webbing which traverses an occupant'"'"'s body. The webbing includes two lap belts which are secured at their ends to a lap belt retractor. The lap retractor is secured below the seat and in a forward position relative to the seat. The lap belt retractor is configured to simultaneously retract the lap belts to thereby retain the position of the buckle assembly over the mid abdomen section of an occupant. The opposing ends of the lap belts are secured in a fixed manner to a lap belt anchor. The lap belt anchor is secured below the seat and in a rearward position relative to the seat. The lap belt anchor may further incorporate a pretensioner which pulls the lap belts rearward and downward. The lap belts slidably engage a buckle assembly along a mid section of the lap belts. The webbing further includes shoulder belts which are secured at their ends to shoulder belt retractors. The opposing ends of the shoulder belts are secured in a fixed manner to the buckle assembly. The lap belt retractor disposed forward of the lap belt anchor pulls the buckle assembly forward and downward. The pretensioner creates a downward force pulling the buckle assembly rearward to better contact the iliac crests of the occupant'"'"'s pelvis.
