Abstract

The present invention provides a seating sensor and a seat device that can prevent a sense of discomfort and appropriately detect seating. The seating sensor is provided with: a pedestal (6) installed on the frame (91a, 91b) of the seat and supported by at least one of a plurality of support springs (92) composed of a wire with a curved portion; and a pressure-sensitive switch. (40A~40F), which are arranged on the base (6). The base (6) has a non-linear recess (7) into which the curved portion of at least one support spring 92 can be inserted. When the curved portion of the spring is fitted into the recessed portion, the base can be disposed across the curved portion of the spring. Therefore, the pressure-sensitive switch disposed on the base can be stably disposed with respect to the spring made of a wire.

Description

technical field [0001] The present invention relates to a seating sensor and a seat device capable of appropriately detecting sitting while preventing a sense of incongruity. Background technique [0002] As a safety system of a vehicle, an alarm system that warns of not wearing a seat belt while riding in a vehicle is practically used. In this warning system, a warning is issued when a seat belt is not sensed while the person is seated. In order to sense that the person is sitting, a seating sensor that senses a load caused by sitting is used in some cases. [0003] A seat device including such a seating sensor is described in Patent Document 1 below. The seat occupancy sensor of the seat device described in this patent document 1 has a plurality of on-off type pressure-sensitive switches, and is arranged between the seat surface of the seat device and the cushion pad covered by the seat surface. . In this seat occupancy sensor, when a pressure is applied to each pressu...
