Seat load detecting device and mounting structure thereof
First Claim
1. A seat load detecting device interposed between a floor-side seat securing member and a seat-side securing member and detecting a load applied to a seat, the detecting device comprising:
- an annular strain portion with an axial line that extends vertically;
an outer peripheral holder mounted to the floor-side seat securing member and holding an outer peripheral edge of the strain portion;
an inner peripheral holder mounted to the seat-side securing member, holding an inner peripheral edge of the strain portion, and having a mounting hole whose axis is oriented in a widthwise direction of the seat and which permits rockable connection to the seat-side securing member; and
at least one detecting element disposed at the strain portion and detecting the load applied to the seat on the basis of an amount of strain between an outer periphery and an inner periphery of the strain portion.

Abstract
In a seat load detecting device, sensor bodies are interposed between an upper rail and respective lower brackets. Each sensor body includes an annular strain portion which axial line extends vertically, an outer peripheral holder which is mounted to the upper rail and which holds an outer peripheral edge of the strain portion, and an inner peripheral holder which is mounted to the lower bracket and which holds an inner peripheral edge of the strain portion. Strain gauges for detecting a load applied to a seat on the basis of a strain amount between an outer periphery and an inner periphery of each strain portion are disposed on each strain portion. A second clamping member of each inner peripheral holder has a mounting hole which is formed through the second clamping member in a widthwise direction thereof and which rockably connects the lower bracket.

10. A mounting structure of a seat load detecting device interposed between a floor-side seat securing member and a seat-side securing member and detecting a load applied to a seat, the mounting structure comprising:
-
an annular strain portion with an axial line that extends vertically; an outer peripheral holder mounted to the floor-side seat securing member and holding an outer peripheral edge of the strain portion; an inner peripheral holder mounted to the seat-side securing member and holding an inner peripheral edge of the strain portion; and at least one detecting element disposed at the strain portion and detecting the load applied to the seat on the basis of an amount of strain between an outer periphery and an inner periphery of the strain portion; a mounting hole whose axis is oriented in a widthwise direction of the seat; and a fastener disposed in the mounting hole, passing through the seat-side securing member, and rockably connecting the seat-side securing member and the inner peripheral holder with each other.
