Abstract

A seated passenger'"'"'s weight detection device includes a seat vertical position adjusting means having a front link and a rear link, a weight detection sensor for detecting a weight of a seated passenger on the basis of an input from the front link and an input from the rear link and a backward and forward input cancel means for canceling backward and forward inputs which operate to the front link and the rear link.

Claims

1. A seated passenger'"'"'s weight detection device comprising:

a seat vertical position adjusting means having a front link and a rear link;

a weight detection sensor for detecting a weight of a seated passenger on the basis of an input from the front link and an input from the rear link; and

a backward and forward input cancel means for canceling backward and forward inputs which operate to the front link and the rear link.

2. A seated passenger'"'"'s weight detection device according to claim 1, wherein the backward and forward input cancel means is a connecting member which connects between the front link and rear link.

3. A seated passengers weight detection device according to claim 1, wherein the backward and forward input cancel means is a connecting member for connecting a slide rail to one of the front link and the rear link which is not connected to an actuator of seat vertical position adjusting means.

4. A seated passenger'"'"'s weight detection device according to claim 1, wherein the backward and forward input cancel means is a connecting member for connecting a seat cushion flame to one of the front link and the rear link which is not connected to an actuator of seat vertical position adjusting means.
