Abstract
A modular automotive seat frame enabling a variety of seat frames to be fabricated of modular components. The seat back frame includes a pair of side supports each including a cross member which nestingly interfit with one another. The amount of nesting is varied to vary the width of the seat back. An upper member is secured between the side supports and is adapted to support a headrest. In an enhanced embodiment, the seat is an all-belts-to-seat design. A belt retractor is mounted to the nested cross members of the side supports and a shoulder belt terminal is mounted on the upper member of the seat back frame. The terminal permits the height of the shoulder belt loop to be adjusted for comfort and safety.
