Attachment structure of a load sensor for a vehicle seat
First Claim
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, 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;
a strain portion defined between each fixed end of the plate-shaped strain unit;
the second attachment bracket being provided with a stopper hole; and
a bolt passing through the stopper hole in the second attachment bracket and through the first attachment bracket, the stopper hole in the second attachment bracket permitting relative vertical movement between the first and second attachment brackets to restrict movement of the plate-shaped strain unit in a vertical direction relative to the vehicle seat upon application of a load to the attachment structure, 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 connected to each other through a connecting rod.

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 includes 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.

8. A load sensor attachment structure in a vehicle seat which is mounted on a vehicle body comprising:
-
a pair of load sensors each comprised of a plate-shaped strain unit and a strain gauge located between opposite ends of the plate-shaped strain unit for detecting a vertical strain of the plate-shaped strain unit;
a pair of first attachment brackets each holding one end of one of the plate-shaped strain units and attached to a seating portion of the vehicle seat;
a pair of second attachment brackets each holding an opposite end of one of the plate-shaped strain units and attached to the vehicle body, the pair of second attachment brackets being positioned on right and left sides of the vehicle seat;
a connecting rod extending between the pair of second attachment brackets and connected by a fastener to each of the second attachment brackets. - View Dependent Claims (9, 10, 11, 12, 13, 14)
