Title:
BREAKAGE DETECTION DEVICE OF OPENING/CLOSING WINDOW GLASS
Document Type and Number:
Japanese Patent JP2009083663
Kind Code:
A
Abstract:

To provide a breakage detection device of opening/closing window glass which can securely detect breakage without malfunction.

A breakage detection device of opening/closing window glass detects the breakage of the window glass 5 capable of opening/closing an opening of a vehicle. A clip 40 is placed at an end of the window glass 5, and is clipped by a force of crushing at the end of the window glass accompanying the breakage of the window glass 5. Magnetic sensors 61, 62 detect displacement of at least a part of the clip 40 accompanying the breakage of the window glass 5. A microcomputer 72 samples output values of the magnetism sensors 61, 62 at predetermined intervals, and detects a temporal variation of the output values of the magnetism sensors 61, 62. The microcomputer 72 determines that the window glass is broken when the temporal variation of the output values of the magnetic sensors 61, 62 is out of an allowable range.
