[0020] Such as figure 1 with 2 As shown in , a seat portion 1 of a vehicle includes a seat cushion member 2 , skin members 5 and 50 , and a weight sensor 4 . The seat cushion member 2 is made of, for example, urethane, and has cushioning properties to be used as a base of the seat. The skin members 5 and 50 are made of fabric, artificial leather or leather and surround the upper and side surfaces of the seat cushion member 2 . The weight sensor 4 is interposed between the cushion member 2 and the skin member 5 .

[0021] The upper surface of the cushion member 2 has a plurality of grooves 3 and the skin members 5 and 50 are drawn into the grooves 3 to match the geometry of the surface of the cushion member 2 . The skin members 5 and 50 are pulled by using the insertion member 10 , the connection members 9 and 90 , and an unillustrated fixing tool for the connection members 9 and 90 . A method of pulling the skin members 5 and 50 into the groove 3 will be described below. ...

no. 2 approach ）

[0042] Such as figure 2 with 7 As shown in , the end portion of the skin member 5 and the end portion of the skin member 50 are coupled together with the end portion of the insertion member 101 in the central portion of the opening of the groove 3, so that the skin members 5, 50 and the insertion A connecting line 241 is created between the components 101 . More specifically, the sides of the end portions of the skin members 5 and 50 are aligned with the sides of the end portion of the insertion member 101 in the same line, ie, in the joining line 241 . The insertion member 101 is made of fabric, for example, and may be in the shape of a bag.

[0043] The insertion member 101 has an opening portion 111 on the opposite side of the insertion member 101 with respect to the coupling line 241 . The opening portion 111 has a rectangular opening that opens on both sides of the insertion member 101 and communicates with the external space on the opposite side of the insertion memb...

[0046] Such as figure 2 with 8 As shown in , the end portion of the skin member 5 and the end portion of the skin member 50 are coupled together with the end portion of the insertion member 102 in the central portion of the opening of the groove 3, so that the skin members 5, 50 and the insertion A joining line 242 is created between the components 102 . More specifically, the sides of the end portions of the skin members 5 and 50 and the sides of the end portion of the insertion member 102 are aligned in the same line, ie, the joining line 242 . The insertion member 102 is made of fabric, for example, and may be in the shape of a bag.

[0047] The opposite side of the insertion member 102 with respect to the coupling line 242 is connected to the connection member 91 . The connection member 91 may be, for example, a resin rod or a metal wire. The connection member 91 is inserted into the insertion member 102 when the insertion member 102 has a bag shape. The insertion me...

Abstract

An attachment structure of a weight sensor for seat occupant detection, comprising: an insertion member (10, 101, 102) extending from a skin member of a seat portion to a in a groove on a cushion member of the seat portion; and at least one connecting member (9, 90, 91) connected to the insert member (10, 91) inside the groove 101, 102) of the second end portion. The opening portion (11, 110, 111, 23) is provided in the insertion member, and the weight sensor is inserted into the insertion member through the opening of the opening portion across the groove.

Description

technical field [0001] The present disclosure relates to an attachment structure of a weight sensor attached to a seat of a vehicle to detect a sitting state of a person. Background technique [0002] Conventionally, there is a technology for detecting the state of a person sitting on a vehicle seat and for controlling various safety devices such as seat belts or air bags installed in the vehicle in order to improve the performance of these safety devices. A film-like membrane switch having flexibility can be used as a weight sensor suitable for detecting such a sitting state of a person. A seat portion and a back portion of a vehicle seat are generally obtained by covering a pad made of urethane or the like with a skin member such as fabric, artificial leather, or leather. More specifically, a skin member is inserted into a groove provided on the surface of the pad, and the inserted skin member is fixed to an anchor member (for example, a wire or a resin rod) provided adja...
