ABSTRACT:
A vehicle seat assembly with integrated safety restraint belts includes a bottom frame and a backrest frame. The backrest frame is pivotally connected to the bottom frame by first and second pivot elements. The first and second pivot elements may include motor driven actuator screws for remotely controlling the pivoted position of the backrest frame under power. The bottom frame includes first and second side rails which are anchored to the outer sill panel and the floor panel, respectively, for providing a sturdy mounting arrangement to withstand high loading and stresses during sudden deceleration. The integrated safety restraint belt includes a shoulder strap segment connected to the upper end of the backrest frame, above the first pivot element, and a lap strap segment. A spool, mounted to the bottom frame, plays out and reels in strap material from a concealed segment interposed between the spool and the shoulder strap segment. The concealed segment of the safety restraint belt is hidden within a hollow stile of the backrest frame. A guide is mounted within the hollow stile, for controlling the concealed segment within the hollow passage during movement of the safety restraint belt to help prevent binding or misalignment when the backrest frame is articulated. An anti-rotation stop plate is formed as part of the bottom frame and positioned to abut a nose portion of the first pivot element in the event of severe loading and deformation resulting from sudden deceleration. In this manner, the anti-rotation stop plate restrains unwanted deformation of the first pivot element relative to the bottom frame.
