Abstract
A seat back includes a backrest formed of a first polymeric material for supporting an occupant. A bracket formed of a different material than the first polymeric material of the backrest is anchored to the backrest for coupling to a seat cushion. A reinforcing composite layer is connected to the backrest and is formed of a second polymeric material and a plurality of fibers impregnated in the second polymeric material. The first polymeric material of the backrest is mechanically engaged with the bracket free of melt bonding between the first polymeric material of the backrest and the bracket. The first polymeric material of the backrest is melt bonded to the second polymeric material of the reinforcing composite layer integrating the backrest, the bracket, and the reinforcing composite layer.
