[0029] A first embodiment of the seating sensor will be described below. In addition, below, the front-back direction of a vehicle is called a "front-back direction."

[0030] Such as figure 1 As shown, the lower rail 2 is fixed to the floor 1 of the vehicle in a state extending in the front-back direction, and the upper rail 3 is connected to the lower rail 2 so as to be movable in the front-back direction relative to the lower rail 2 .

[0031] In addition, the lower track 2 and the upper track 3 are both in the width direction ( figure 1 The rails are arranged in pairs in the direction perpendicular to the paper surface), and the rails arranged on the right side facing forward are shown here. Furthermore, a seat 5 forming a seating portion for passengers is fixed and supported on the two upper rails 3 .

[0032] The seat 5 is configured to include a seat cushion 6 forming a seat surface, and a seat back 7 supported at a rear end portion of the seat cushion 6 so as to b...

Abstract

The invention provides a seating sensor which gives consideration to both detection performance and seating feeling. The seating sensor includes: a holder (31) configured to be mounted, in a state ofbeing sandwiched between a cushion member (20) of a seat cushion of a vehicle and a support member (SU) supporting the cushion member (20), on the support member (SU), and including a first pressure receiving portion (33) positioned on a first plane (P1) expanding along the support member and a second pressure receiving portion (34) connected to the first pressure receiving portion and positionedon a second plane (P2) expanding along the support member (SU) in a state of crossing the first plane (P1); and a sensor body (40) placed on the holder to extend over the first pressure receiving portion (33) and the second pressure receiving portion (34) and configured to detect information of a load applied from the cushion member.

Description

technical field [0001] The present invention relates to seat occupancy sensors. Background technique [0002] Conventionally, as a seat occupancy sensor, for example, a sensor described in Patent Document 1 is known. The seat occupancy sensor is provided with a holder arranged under a cushion member of a seat cushion of a vehicle and mounted on a support member (a plurality of S springs) supporting the cushion member, and mounted on the holder to detect a load from the cushion member. The sheet-shaped sensor body of the load information. In addition, the support member is located on a plane that expands substantially horizontally, and the holder that is a pressure receiving surface of the load is located on a plane that expands approximately horizontally in the manner of the support member above the support member. [0003] Patent Document 1: CN203331880U ( Figure 1 ~ Figure 3 ) [0004] However, the supporting member does not necessarily lie on a single plane, for examp...
