Abstract: An automotive seat back having a pair of spaced upright members with lower ends and upper ends interconnected by a cross member to define a substantially rectangular back frame. The upright members and the cross member also have a front surface and a rear surface. A shoulder belt housing extends upwardly between the upright members from below the cross member to an upper distal end disposed above the cross member. The shoulder belt housing also extends forward of the front surfaces of the upright members and the cross member. Specifically, the front surfaces define a frontal plane of the back frame and the distal end of the shoulder belt housing extends forwardly beyond the frontal plane of the back frame. The housing includes a coffin portion, defined by side walls and a bottom, and a cover disposed over and in sealing engagement with the side walls. A seat belt passes within the coffin portion and out through an opening in the cover to overlay a front surface of the seat back.

Abstract: An automotive seat back (34) which comprises a pair of spaced upright members (40) each having lower ends rotatably supported on pivot pins (38) and interconnected by a cross member (42) extending between the upper ends. A shoulder belt housing (44) extends upwardly between the upright members (40) from below the cross member (42) to a distal end (46) disposed above and outside the cross member (42). Crisscrossing truss elements (52) interconnect the upright members (40) and the housing (44) to suspend the housing (44) within the periphery of the seat back as defined by the upright members (40) and the cross member (42). The upright members (40) and the cross member (42) and the truss elements (52) and the housing (44) are all integrally die cast of magnesium. The housing (44) includes a coffin portion, defined by side walls (54) and a bottom (56), and a cover (58) disposed over and in sealing engagement with the side walls (54).
