Abstract: To provide a seat occupancy sensor capable of detecting that an occupant is seated on a seat, a seat occupancy sensor provided in a vehicle seat includes a pair of switch modules disposed in an occupant seating area of a seat cushion, wherein; each of the switch modules includes a first pressure-sensitive switch and a second pressure-sensitive switch that are disposed on a front part so as to be laterally spaced from each other and a third pressure-sensitive switch disposed on a rear part; each of the switch modules is configured to be turned on when at least one of the first pressure-sensitive switch and the second pressure-sensitive switch is on and the third pressure-sensitive switch is on; and the seat occupancy sensor is configured to be turned on when the switch modules are both on.

Abstract: 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.

Abstract: 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.
