Abstract: A vehicle seat (10) includes an improved seat frame member (14) used as a seat back, a recliner mechanism connection (16) and a vehicle seat track actuator mechanism (18). The seat back frame member (14) includes a side frame member (30) having a side frame structural member (32) preferably made from a relatively high strength steel and a stiffening insert member (42) to provide strength and rigidity to the recliner mechanism connection (16) and to reduce the overall mass of the vehicle seat frame member and thereby the vehicle seat (10). The seat frame member (14) further includes a recliner mechanism (34) welded to the side frame structural member (32) preferably utilizing a shaped laser weld pattern (40). The vehicle seat track actuator mechanism (18) includes a bar (56), first and second pivot pins (62, 64) and connectors (70).

Abstract: A one-piece seat back frame for use in a vehicle seat assembly including a first side portion, a second side portion, an upper cross portion, a lower cross portion coupled together to form a rectangular unitary frame structure. The seat back frame also includes an inner wall extending from a front surface and an inner edge of the back frame, and an outer wall extending from the front surface and an outer edge of the back frame, thereby forming a channel on the front surface. A plurality of formations are formed in the back frame to enhance the strength and stiffness of the back frame. The seat back frame also includes a plurality of apertures for attaching other seat components, such as a head restraint assembly. The seat back frame is formed from at least one of a monolithic blank, a tailored welded blank, and/or a tailored welded coil.
