Abstract: A seat belt restraint anchorage member adapted for mounting to the underside of a vehicle floor pan enabling the belt load to be transferred by the member to the vehicle main frame. The anchorage member is fabricated from a one piece elongated sheet metal strip having, in cross sectional view, a leading end portion bent into a closed polygonal-shaped loop terminating in an elongated rearwardly extending blade portion. The loop is formed by a plurality of planar segments one of which is in flush attachment with an opposed upwardly contoured hump portion of the vehicle floor pan. The anchorage member is welded to the underside of the floor pan as a sub-assembly enabling the anchorage member and floor pan to be readily attached to the vehicle main frame at the assembly plant. Applicants' invention allows the seat belt loads to be conducted through the reinforcing anchorage member into an aft portion of the main frame thereby minimizing strain of the body shell.
