Abstract

A seating detecting device is comprised of a first cushion having an insert wire embedded therein, a second cushion placed on the first cushion, a surface sheet placed on the second cushion, a suspension wire fixed to the surface sheet and arranged between the surface sheet and the second cushion, and a pressure detecting device provided between an upper surface of the first cushion and a lower surface of the second cushion and having a plurality of through-holes for the suspension wire being fixed by the insert wire therethrough thereby to fix the surface sheet to the first and second cushions.

Claims

1. A seating detecting device comprising:

a first cushion having an insert wire embedded therein;

a second cushion placed on the first cushion;

a surface sheet placed on the second cushion;

a suspension wire fixed to the surface sheet and arranged between the surface sheet and the second cushion;

a pressure detecting device provided between an upper surface of the first cushion and a lower surface of the second cushion and having a plurality of through-holes; and

a fixing member which fixes the suspension wire and the insert wire at a position defined by at least one of the through-holes to fix the surface sheet to the first and second cushions.

2. A seating detecting device according to claim 1, wherein at least some of the through-holes in the pressure detecting device are arranged in rows which are parallel to one another.

3. A seating detecting device according to claim 1, wherein the plurality of through-holes is arranged along a first direction and a second direction, and the first direction crosses the second direction.

4. A seating detecting device according to claim 2, wherein the plurality of through-holes is arranged along a first direction and a second direction, and the first direction crosses the second direction.

5. A seating detecting device according to claim 1, wherein the pressure detecting device includes a plurality of pressure detecting elements.

6. A seating detecting device according to claim 2, wherein the pressure detecting device includes a plurality of pressure detecting elements.

7. A seating detecting device according to claim 1, wherein the second cushion includes a plurality of through-holes corresponding to the plurality of through-holes of the pressure detecting device.

8. A seating detecting device according to claim 2, wherein the second cushion includes a plurality of through-holes corresponding to the plurality of through-holes of the pressure detecting device.

9. A seating detecting device comprising:

a first cushion provided with an insert wire;

a surface sheet;

a second cushion positioned between the first cushion and the surface sheet;

a suspension wire fixed to the surface sheet and positioned between the surface sheet and the second cushion;

a pressure detecting device provided between the first cushion and the second cushion, the pressure detecting device being provided with a plurality of through-holes; and

the suspension wire and the insert wire being fixed to each other through the through-holes in the pressure detecting device to fix the surface sheet relative to the first and second cushions.

10. A seating detecting device according to claim 9, wherein the insert wire is embedded in the first cushion.

11. A seating detecting device according to claim 9, wherein the pressure detecting device is positioned between an upper surface of the first cushion and a lower surface of the second cushion.

12. A seating detecting device according to claim 9, wherein the through-holes are arranged along a first direction and a second direction, with the first direction crossing the second direction.

13. A seating detecting device according to claim 9, wherein the pressure detecting device includes a plurality of pressure detecting elements.

14. A seating detecting device according to claim 9, wherein at least some of the through-holes in the pressure detecting device are arranged in rows which are parallel to one another.

15. A seating detecting device according to claim 9, including fixing members which fix the suspension wire to the insert wire.
