Abstract: It is intended to improve texture of a decoration using a stitch line while improving workability in sewing for forming the stitch line at a skin material, to promote manufacturing efficiency as compared to formation of a stepped shape only by sewing, and to reduce the number of steps. A skin material is used for a conveyance seat, and is molded using a die. The skin material includes a linearly-extending stepped portion having a stepped shape transferred from the die, and a stitch line sewn along the stepped portion. The stepped portion serves as a guide upon formation of the stitch line.

Abstract: A conveyance seat configured to stabilize a position of a temperature detection unit to suppress positional deviation of the temperature detection unit is described. The conveyance seat comprises a cushion pad, a bottom plate, an electric heater which is attached to the cushion pad, a thermistor which detects temperature at a location between the cushion pad and the bottom plate during operation of the electric heater, a housing cavity with a hollowed shape formed in a bottom portion of the cushion pad, and a holding pad which holds the thermistor within the housing cavity by being fit in the housing cavity with the thermistor attached thereto. The thermistor is held by the holding pad, and is positioned between the cushion pad and the holding pad, within the housing cavity.

Abstract: The present disclosure provides a conveyance seat that can discharge liquid splashed on a cover member of the seat so that clothing does not get wet with the liquid remaining on the cover member. A conveyance seat includes a bottom plate and a cover member attached to the bottom plate. A discharge hole for discharging the liquid splashed on the cover member is formed in the bottom plate. The cover member includes: a slit by which the surface is divided; and welded portions where portions of the cover member divided by the slit are welded together. The welded portions are inclined toward the discharge hole to form discharge lines which guide discharge of the liquid splashed on the cover member.

Abstract: A seat device that is capable of improving body pressure distribution during traveling is provided. In a seat device including a seating seat, in both of end portions in the seat width direction of the seating seat, at positions interposed between the bottom plate and a cushion member of the seating seat, turning plates are provided. The parts of the cushion member, where the turning plates are provided between the same and the bottom plate, constitute turning parts that turn around edges thereof on the width direction inner sides as base points, as the turning plates turn. In the cushion member, slits are formed at boundary positions between the turning parts and a non-turning part, that is, a part other than the turning parts.
