SUPPORT STRUCTURE FOR LOAD MEASUREMENT SENSOR
First Claim
1. A support structure for a load measurement sensor which supports the load measurement sensor, comprising:
- a sensor body that detects a load applied to a seat; and
an extension shaft portion extending from the sensor body, by way of a support bracket in a state where the extension shaft portion is positioned at a side portion of the sensor body;
the sensor body comprising;
a deformation portion which is deformed to be curved inward in a radial direction of the extension shaft portion by receiving the load; and
a regulation portion which is positioned inside relative to the deformation portion in the radial direction and comes into contact with the deformation portion to regulate a deformation amount of the deformation portion;
the regulation portion being disposed in an axial direction of the extension shaft portion at a position that includes a load center point of the load applied to the deformation portion by the seat.

Abstract
Provided is a support structure for a load measurement sensor having sufficient durability without adding a large load to a portion transmitting a load to the load measurement sensor. In a support structure for a load measurement sensor, including a sensor body detecting a load generated from a seat having a seat frame and an extension shaft portion extending from the sensor body, by way of attachment brackets in the state where the extension shaft portion follows the horizontal direction, the support structure includes a load input portion which comes into contact with the sensor body and inputs a load to the sensor body, the sensor body includes a load receiving surface which contacts the load input portion and receives the load, and the load input portion is formed to be movable in the axial direction of the extension shaft portion with respect to the load receiving surface.
