Abstract

A vehicle seat is provided. The vehicle seat includes a sheet-like sensor member, a sheet-like electric device, and a seat main body configuring a sitting portion and including therein the sensor member and the electric device while overlapping each other. The electric device is provided between a pad member which forms a cushion element of the seat main body and a skin cover which covers an outer surface side of the pad member, and the sensor member is provided between the electric device and the skin cover. The electric device is formed with a through hole, so that a measuring circuit unit which is wired and connected to the sensor member is provided in an inner surface side of the electric device, and the measuring circuit unit is accommodated in a recessed portion formed in the pad member.

Claims

1. A vehicle seat comprising:

a sheet-like sensor member;

a sheet-like electric device; and

a seat main body configuring a sitting portion and including therein the sensor member and the electric device while overlapping each other,

wherein the electric device is provided between a pad member which forms a cushion element of the seat main body and a skin cover which covers an outer surface side of the pad member, and the sensor member is provided between the electric device and the skin cover, and

wherein the electric device is formed with a through hole, so that a measuring circuit unit which is wired and connected to the sensor member is provided in an inner surface side of the electric device, and the measuring circuit unit is accommodated in a recessed portion formed in the pad member.

2. The vehicle seat according to claim 1,

wherein a wiring connecting the sensor member and the measuring circuit unit passes the through hole formed in the electric device.

3. The vehicle seat according to claim 2,

wherein the through hole is configured as a slit which is connected to an edge of the electric device, through which the wiring passes so that the measuring circuit unit is provided in the inner surface side of the electric device.

4. The vehicle seat according to claim 1,

wherein the through hole is configured such that the measuring circuit unit passes the through hole.

5. The vehicle seat according to claim 1,

wherein both the sensor member and the electric device are provided within a seat cushion configuring the sitting portion,

wherein a lower end portion of a seatback configuring a backrest is provided on a rear end portion of the seat cushion, and

wherein the recessed portion in the pad member is provided at a position where the lower end portion of the seatback is provided thereabove.

6. The vehicle seat according to claim 1,

wherein the sheet-like electric device is provided to cover the recessed portion formed in the pad member.

7. The vehicle seat according to claim 1,

wherein the sensor member includes a measuring electrode surface of an electrostatic condenser type sensor element for detecting a sitting condition of a sitting person, and

wherein the electric device is configured as a sheet-like heater device for warming up a portion of the sitting person which is brought into contact therewith by heat generated by the electric device being energized.

8. A vehicle seat comprising:

a seat main body including a pad member which configures a cushion element, and a skin cover which covers the pad member;

a sheet-like sensor member; and

a sheet-like electric device, the sheet-like sensor member and the sheet-like electric device being overlapped with each other and provided between the pad member and the skin cover,

wherein one of the sensor member and the electric device includes a control unit connected thereto through a wiring and laminated on the other of the sensor member and the electric device, and

wherein the other of the sensor member and the electric device is formed with a through hole, through which the wiring passes.

9. The vehicle seat according to claim 8,

wherein the control unit is accommodated in a recessed portion formed in the pad member.

10. The vehicle seat according to claim 9,

wherein the seat main body includes a seatback provided above the pad member at a rear side thereof, and

wherein the recessed portion is formed in the pad member below the seatback.
