Provided is a composite material for vehicles capable of substantially preventing the occurrence of wrinkles caused by ease stitching. This composite material for vehicles is a layered product of a skin material and a polyurethane foam sheet. The skin material has a play structure which, when the composite material for vehicles is stitched, allows the skin material to follow deformation caused by the stitching with a smooth state of a surface of the skin material maintained. The skin material is a woven fabric including warp yarns and weft yarns. The warp yarns and/or the weft yarns include two or more types of yarns having different total finenesses, and form the play structure.

Composite material for vehicles

A seat back configured to support a back of a seated person includes a back frame constituting an internal framework; and an elastic mat fitted to the back frame so as to cover the back frame from a front side, the elastic mat having a planar shape and being configured to elastically support the back of the seated person. The back frame includes a frame body and a support wire that protrudes forward from the frame body. The elastic mat includes a main support portion configured to support the back of the seated person, and a band portion that extends from a back surface of the main support portion, the band portion being wound around the support wire. The elastic mat has a through-hole through which a head at a distal end of the wound band portion is inserted such that the head is snap-fitted in the through-hole.

Seat back

A seat back configured to support a back of a seated person includes a back frame that constitutes an internal framework; and an elastic mat that is fitted to the back frame so as to cover the back frame from a front side, the elastic mat having a planar shape and being configured to elastically support the back of the seated person. The back frame includes a frame body and a support wire that protrudes forward from the frame body. The elastic mat includes a plurality of hooks provided on a back surface of a main support portion configured to support the back of the seated person, the hooks being engaged with the support wire to fix the elastic mat to the support wire.
