Clip for detecting window glass breakage

Abstract

A window glass breakage detecting clip for detecting breakage of window glass of a vehicle based on a change in the state of mounting of a detection target member relative to the window glass. The breakage detecting clip has a first section and a second section bent so as to face each other and sandwiching an end of the window glass. When the window glass is not broken, the first and second sections sandwich the window glass, maintaining contact therewith at positions displaced from each other in planes thereof, and are urged by the elasticity of the first and second sections in the direction in which the first and second sections approach each other. When the window glass breaks, the first and second sections elastically deform to crush the end of the window glass, changing the state of mounting of the detection target member relative to the window glass.

Description

technical field [0001] The invention relates to a clip for window glass breakage detection. Background technique [0002] Patent Document 1 discloses a device for detecting breakage of a window glass of a vehicle in order to prevent theft. like Figure 30 As shown, the device is equipped with a compression coil spring 220, and when the window glass 200 is in the fully closed position for closing the window opening, the bearing plate 211 of the linear window shaker 210 supporting the window glass 200 is closed to the window glass 200. direction push. If the window glass 200 is damaged, the restriction caused by the stop pin 205 provided in the window glass 200 and the locking part 206 provided in the vehicle body is released, and the compression coil spring 220 is used to push the bearing plate 211 toward the window glass 200. The closed side moves from the fully closed position. The limit switch 230 detects the movement of the carrier plate 211 to detect breakage of the w...

AI Technical Summary

Problems solved by technology

If the window glass is impacted, it will be broken into powder, but there may be a part of the window glass that is not crushed and remains

In particular, in the detection device described above, if the window glass 200 remains near the carrier plate 211, the carrier plate 211 will not move in the closing direction, and thus the breakage of the window glass 200 may not be detected.
