There is provided a vehicle seat (car seat) comprising a seat cushion pad (seat body) having an air passage connected to an outlet port (114), and a blower having an inlet port (113) and configured to feed air taken in through the inlet port (113) to the air passage. The blower (100) is located on the lower side of the seat cushion pad (seat body) that is opposite to an occupant's side on which an occupant is to be seated, and the inlet port (113) is directed upward that is a direction toward the seat cushion pad (seat body).

A seat support is provided with a plurality of layers of a non-foam material to mount to a seat frame and to support an occupant upon the seat frame. The plurality of layers is stacked upon each other, and each of the plurality of stacked layers has a generally uniform thickness.

A back panel of a motor vehicle seat includes, on its visible external back side, a thermal layer.

There is provided a conveyance seat that suppresses the deterioration of the sensitivity of a load sensor to an input load even when a heater wire and the load sensor are disposed to overlap each other. A conveyance seat includes a seat cushion that supports buttocks of an occupant; a seat back connected to the seat cushion to serve as a backrest for the occupant; a load sensor provided at the seat cushion or at a portion of the seat back; a heater wire disposed on an occupant side with respect to the load sensor; and an intermediate member that positions the heater wire. The intermediate member is disposed between the load sensor and the heater wire.

A seat includes comprising: a seat bottom and a seat back operatively engaging the seat bottom. At, least one of the seat back and the seat bottom has an air impermeable outer trim layer covering at least a portion of an outer surface. The air impermeable outer trim layer includes perforations extending therethrough. The, size, spacing, or both of the perforations varies based at least in part on a body pressure map, and the perforations are configured to allow airflow therethrough directed toward an occupant of the seat.

Provided is a conveyance seat in which a duct connected to a fan can be compactly disposed, and the fan is provided in a pan-frame-type seat cushion. The vehicle seat includes a seat cushion (S2) and a blower (48) provided in the seat cushion (S2). The seat cushion (S2) is provided with a plate-shaped pan frame (42). The blower (48) is provided below the pan frame (42), a duct (49) is connected to the blower (48), and an opening (42a) through which the duct (49) extends is formed in the pan frame (42).

The present disclosure describes vehicle seats having integral components for use with ventilation, air conditioning, and/or heating systems. Air ducting can be incorporated into the seat base and the seat back. Further, air can be directed through a rear-facing outlet vent in the seat back, providing improved ventilation, air conditioning, and/or heating for rear passengers of a vehicle.

A wire harness connected to a sensor is positioned on a back surface of a pad of a vehicle seat supported by a panel. The vehicle seat (1) includes a panel (4); a pad (11, 51) supported by the panel; a skin material (12, 52) covering a front surface of the pad; and a sensor (32) provided between the front surface of the pad and the skin material for acquiring information on a seat occupant, wherein the pad is provided with a through hole (35, 58) passed from the front surface of the pad to a back surface of the pad, and a recess (45, 61) formed in the back surface of the pad and connected to the through hole, the wire harness connected to the sensor extending in the through hole and the recess.

A seat adjustment system for a vehicle seat is provided. The seat adjustment system includes a seat body; at least one actuating unit, configured to adjust a support of the seat body; a sensing unit, configured to obtain and provide seat information and body shape data of a back of an occupant; and a control unit, configured to control the at least one actuating unit; wherein when one parameter of the seat body changes, the control unit makes a portion of the body shape data of the occupant in a pre-defined range via the at least one actuating unit.

Heating and cooling device for a vehicle seat with separating material (2) that forms at least a portion of an air-distribution chamber (1), with an upper-side layer (4) covering the separating material (2) on its upper side, with a lower-side layer (5) of separating material (2) on the underside opposite from the upper-side layer (4) that is essentially airtight whereby the upper-side layer (4) and the lower-side layer (5) are connected together about the outer circumference of the separating materials (2). An air-inlet aperture (6) is provided to the air-distribution chamber (1) and air-outlet apertures (10) are provided in the upper-side layer (4) to remove air from the air-distribution chamber (1). The upper-side layer (4) and the lower-side layer (5) are connected at least about their outer circumference by a box-shaped insert (3).
