TENSION DETECTOR AND CHILD SEAT DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a tension detector capable of securely detecting tension which worked on a weaving belt and a child seat detector capable of securely determining whether "normal mounting state" or "child seat mounting state".

SOLUTION: A compression coil spring 72 is provided between a pressing piece 76 pressed to and contacted with a head 112 of a force sensor 92 and a pressing plate 58 for moving with an anchor plate 22 and a compression coil spring 88 is provided on a side of the pressing piece 76 of the compression coil spring 72. Dimensional backlash is absorbed as these compression coil springs 72, 88 are compressed in an opposite direction of the pressing piece 76 and the pressing plate 58 according to the dimensional backlash. Thus, tension of the weaving belt can be securely and continuously detected and determination of "normal mounting state" or "child seat mounting state" can be securely made.
