摘要:
A seating detection device includes a sensor holder located below a cushion pad, a pressure-sensitive switch held by the sensor holder, and a pressing element that is elastically supported by the sensor holder. The pressing element presses the pressure-sensitive switch with a seat load transmitted through the cushion pad.

In a mounting structure of mounting a load detection device, the pitch distance between the detecting portions is adjustable by utilizing a recessed portion formed in a member on which the load detection device is mounted so as to accelerate the common use of the load detection device, which can lead to a cost reduction. The load detection device is mounted on the cushion member in such a manner that the respective detecting portions are disposed on the respective detecting portion disposing portions, the one or more connecting portions are disposed on the connecting portion disposing portions, respectively, and the third connecting portion crossing over the groove portion is disposed in the groove portion. Accordingly, the detecting portions are disposed on both sides of the groove portion, that is, the detecting portions are disposed putting the groove portion therebetween. Thus, the pitch distance between the detecting portions is adjustable by utilizing a groove portion, that is, by disposing the third connecting portion in the groove portion.

A vehicle seat occupancy sensor (10) disposed in a vehicle seat (18) includes a plurality of sensor elements (14) that each activate upon receiving a pressure of a predetermined value or greater. At least two of the sensor elements (14a, 14b) are arranged along a line (L1) that is inclined from a center line of the seat which extends in a longitudinal direction of the seat, to only one of a leftward direction and a rightward direction at an inclination angle within a range of 7° to 16.5°.

A seat occupancy sensor includes: a first sensor group (25) having a plurality of first sensor cells (26F, 26C, 26R) that are arrayed in a front-rear direction of a seat and become conductive as a load is applied thereto; a second sensor group (27) having a plurality of second sensor cells (28F, 28C, 28R) that are arrayed in the front-rear direction, farther on a front side of the seat and closer to an end of the seat in a width direction than the first sensor group (25), and that become conductive as a load is applied thereto; and an electronic control unit (30). The electronic control unit (30) determines that someone is sitting on the seat when both of at least one of the plurality of first sensor cells (26F, 26C, 26R) and at least one of the plurality of second sensor cells (28F, 28C, 28R) become conductive.
