Abstract: An attachment of a surface cover to a seat back in a vehicle seat having through-holes is described. A bucket seat includes a pad provided with through-holes, a surface cover configured to cover a front surface of the pad, and a back frame disposed on a back side of the pad. The back frame includes: a support portion provided with through-holes positioned to face the first through-holes, the support portion being configured to support the pad; and retaining portions provided around the through-holes and configured to retain hooks of the surface cover. The support portion and the retaining portions are integrally molded.

Abstract: A vehicle seat includes a cushion material and a cover for covering the cushion material. The cover includes a load receiving portion configured to receive a load of a seated occupant. The load receiving portion includes a large thickness portion and a small thickness portion that are located next to each other in a first direction that intersects with a thickness direction of the cover. Each of the large and small thickness portions includes an elastic layer compressive in the thickness direction and a lower cover layer located closer to the cushion material than the elastic layer in the thickness direction. The elastic layer of the small thickness portion is compressed such that the thickness of the small thickness portion is smaller than the thickness of the large thickness portion. The lower cover layer of the large thickness portion is partially cut off to form a cutoff portion.

Abstract: A two-wheeled motor vehicle seat device with a backrest provided on a seat main body so as to be movable in a fore-and-aft direction is provided in which the backrest is provided on the seat main body mounted on a vehicle body so that the backrest can move in a fore-and-aft direction thereof, a heater is incorporated into the backrest, and a harness connected to the heater is passed through an interior of the seat main body and connected to a power supply. This enables the heater to be incorporated into the backrest to heat the backrest without interfering with the fore-and-aft movement of the backrest.
