Embodiment Construction

[0018] like figure 1 As shown, the occupant detection sensor 1 according to one embodiment of the present disclosure includes a sensor body 11 and a connector 12 . The sensor main body 11 includes a plurality of sensor parts 2 and a plurality of coupling parts 3 .

[0019] Each sensor section 2 makes and breaks electrical connection according to the load. like figure 2 As shown, each sensor part 2 includes a first film member 21 , a second film member 22 , a spacer member 23 and an adhesive 24 .

[0020] The first film member 21 has a flat film shape and is mainly made of flexible resin such as polyethylene naphthalate (PEN). In one side portion of the first film member 21, the silver layer C1 and the carbon layer C2 are stacked. The silver layer C1 is made of silver (Ag), which is a conductive material and is formed by printing. The carbon layer C2 is made of carbon, and is formed by printing on the surface of the silver layer C1. The other side portion of the first fi...

Abstract

The sensor has a body and a connector, where the body has a set of films (41, 42) and a spacer (43). A coupling section is coupled with a section of the sensor, where the coupling section comprises a curved part that is curved along a fixing groove of a seat of a vehicle. A relative position of one of the films to another film is offset in a direction to absorb a stress generated by the curved part with respect to an upright before the curved part is formed. The films are provided with conductive layers including carbon. An independent claim is also included for a method for manufacturing a sensor.

Description

technical field [0001] The present invention relates to occupant detection sensors. Background technique [0002] Some vehicles include an occupant detection sensor that detects occupant seating based on load, as disclosed in JP-A-2006-32150. The occupant detection sensor may be made of a flexible film. [0003] A cushion pad of a vehicle seat on which an occupant detection sensor is provided has a hanging groove. In the case where the occupant detection sensor is made of a film, the film is bent according to the shape of the hanger groove. Stress is generated when the membrane is bent, and the sensor part is subjected to a load caused by this stress. Therefore, the accuracy of the sensor may decrease. In addition, the sensor part may be damaged and the membrane may be separated from the spacer. Contents of the invention [0004] An object of the present disclosure is to provide an occupant detection sensor that can have high sensor accuracy and reduce damage to a sen...
