Abstract

An attachment structure installs a load sensor between a seating portion of a vehicle seat and a vehicle body through an attachment structure unit. The attachment structure unit is comprised of a first attachment bracket for holding one end of the strain unit, and a second attachment bracket for holding the other end of the strain unit. At least a pair of attachment structure units are arranged at right and left portions of a front side, right and left portions of a back side, or right and left portions of the front and back sides of the seating portion relative to the vehicle seat and the first attachment brackets of the attachment structure units of the right and left are connected to each other through a connecting rod.

Claims

1. An attachment structure for installing a load sensor between a seating portion of a vehicle seat and a vehicle body through the attachment structure, the load sensor having a plate-shaped strain unit and a strain gauge for detecting a vertical strain of the plate-shaped strain unit, comprising;

an attachment structure unit having a first attachment bracket for holding one end of the plate-shaped strain unit forming the load sensor and attached to the seating portion of the vehicle seat and a second attachment bracket for holding the other end of the plate-shaped strain unit and attached to the vehicle body; and

a strain portion defined between each fixed end of the plate-shaped strain unit, wherein

at least a pair of attachment structure units is arranged at right and left portions of a front side, right and left portions of a back side, or right and left portions of the front and back sides of the vehicle seat relative to the seating portion and at least a pair of the first attachment brackets is arranged at both the right and left portions of the front side, the back side, or the front and back sides of the seating portion relative to the vehicle seat and connected to each other through a connecting rod.

3. An attachment structure of a load sensor for a vehicle seat according to claim 1, wherein at least a pair of the second attachment brackets are arranged at both right and left portions of a front side, a back side, or the front and the back sides of the seating portion and connected to each other through another connecting rod.

2. An attachment structure for installing a load sensor between a seating portion of a vehicle seat and a vehicle body through the attachment structure, the load sensor having a plate-shaped strain unit and a strain gauge for detecting a vertical strain of the plate-shaped strain unit, the attachment structure comprising;

an attachment structure unit having a first attachment bracket for holding one end of the plate-shaped strain unit forming the load sensor and attached to the seating portion of the vehicle seat and a second attachment bracket for holding the other end of the plate-shaped strain unit and attached to the vehicle body; and

a strain portion defined between each fixed end of the plate-shaped strain unit, wherein

at least a pair of attachment structure units is arranged at right and left portions of the front side, right and left portions of a back side, or right and left portions of the front and back sides of the vehicle seat relative to the seating portion, and at least a pair of the second attachment brackets is arranged at both the right and left portions of the front side, the back side, or the front and the back sides of the seating portion and connected to each other through a connecting rod.
