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. ## Claims ### Claim 1 A vehicle seat, comprising a seat cushion and a seat back, wherein the seat cushion includes: a pad; a skin material covering an upper surface of the pad; and a sensor provided between the upper surface of the pad and the skin material for acquiring information on a seat occupant, wherein the pad is provided with a through hole passed from the upper surface of the pad to a lower surface of the pad, and a recess formed in the lower surface of the pad and connected to the through hole, the sensor being connected to a wire harness extending in the through hole and the recess, wherein the pad includes a rigid part and a soft part with higher flexibility than the rigid part, wherein the soft part is located above the rigid part, wherein the through hole is formed to pass through both the rigid part and the soft part, and wherein the recess extends in a rear direction from an opening of the through hole. ### Claim 2 (depends on 1) The vehicle seat according to claim 1, wherein the recess is formed in the rigid part. ### Claim 3 (depends on 1) The vehicle seat according to claim 1, wherein a part of a wall surface formed in the rigid part defining the through hole is located behind a wall surface formed in the soft part defining the through hole. ### Claim 4 (depends on 1) The vehicle seat according to claim 1, wherein a part of a wall surface formed in the rigid part defining the through hole is located in front of a wall surface formed in the soft part defining the through hole. ### Claim 5 (depends on 1) The vehicle seat according to claim 1, wherein a diameter of a part of the through hole formed in the rigid part is larger than the diameter of a part of the through hole formed in the soft part. ### Claim 6 (depends on 1) The vehicle seat according to claim 1, wherein the skin material extends from an upper surface to a rear end of the lower surface, and wherein the recess is located in front of the skin material at the rear end of the lower surface. ### Claim 7 (depends on 1) The vehicle seat according to claim 1, wherein the rigid part comprises a receiving through hole to receive the soft part, and wherein a width of the recess along left and right direction is larger than a width of the receiving through hole formed in the rigid part along left and right direction. ### Claim 8 A vehicle seat, comprising a seat cushion and a seat back, wherein the seat cushion includes: a pad; a skin material covering an upper surface of the pad; and a sensor provided between the upper surface of the pad and the skin material for acquiring information on a seat occupant, wherein the pad is provided with a through hole passed from the upper surface of the pad to a lower surface of the pad, and a recess formed in the lower surface of the pad and connected to the through hole, the sensor being connected to a wire harness extending in the through hole and the recess, wherein the pad includes a rigid part and a soft part with higher flexibility than the rigid part, wherein the soft part is located above the rigid part, wherein the through hole is formed to pass through both the rigid part and the soft part, and wherein the rigid part includes an inclined surface inclined upward toward the rear, the inclined surface being located behind the through hole formed in the rigid part. ### Claim 9 (depends on 8) The vehicle seat according to claim 8, wherein the soft part includes an inclined surface overlapping with the inclined surface included in the rigid part, and the through hole passes through both of the inclined surfaces. ### Claim 10 (depends on 8) The vehicle seat according to claim 8, wherein an upper surface of the soft part includes a rear inclined portion, and the through hole opens at the rear inclined portion. ### Claim 11 (depends on 8) The vehicle seat according to claim 8, wherein the recess is located below the inclined surface formed in the rigid part. ### Claim 12 A vehicle seat, comprising a seat cushion and a seat back, wherein the seat cushion includes: a pad; a skin material covering an upper surface of the pad; and a sensor provided between the upper surface of the pad and the skin material for acquiring information on a seat occupant, wherein the pad is provided with a through hole passed from the upper surface of the pad to a lower surface of the pad, and a recess formed in the lower surface of the pad and connected to the through hole, the sensor being connected to a wire harness extending in the through hole and the recess, wherein the pad includes a rigid part and a soft part with higher flexibility than the rigid part, wherein the soft part is located above the rigid part, and wherein the through hole is formed to pass through both the rigid part and the soft part. ### Claim 13 (depends on 12) The vehicle seat according to claim 12, wherein a blower is provided in the pad, and an opening of the through hole formed at the lower surface of the pad is located lower than the blower. ### Claim 14 (depends on 12) The vehicle seat according to claim 12, wherein the seat cushion is supported by a panel, wherein the rigid part comprises a receiving through hole to receive the soft part, wherein the receiving through hole is located in front of the through hole formed in the rigid part, and wherein a lower surface of the soft part received in the receiving through hole touches the panel. ### Claim 15 (depends on 14) The vehicle seat according to claim 14, wherein a part of the sensor is located above the lower surface of the soft part touching the panel. ### Claim 16 (depends on 12) The vehicle seat according to claim 12, wherein the soft part includes a protrusion portion at a center of a lower surface, and a part of sensor overlaps a thickest part of the soft part corresponding to the protrusion portion. ### Claim 17 (depends on 12) The vehicle seat according to claim 12, wherein the part of the rigid part located forward to the through hole includes an inclined surface inclined upward toward the rear, and the part of the sensor overlaps the inclined surface. ### Claim 18 (depends on 12) The vehicle seat according to claim 12, wherein the seat cushion includes a heater cloth with a heater wire provided on the pad, wherein the heater cloth has a main body and a pair of connecting portions extending rearward from a rear edge of the main body, and wherein an opening of the through hole at the upper surface of the pad is positioned between the pair of connection portions. ### Claim 19 (depends on 12) The vehicle seat according to claim 12, wherein the pad is provided with a pair of locking portions arranged with left and right directions, and an opening of the through hole at the surface is located between the pair of locking portions in a top view.
