Title:
VISOR AND NIPPING-IN JUDGING DEVICE AND OPENING AND CLOSING DEVICE
Document Type and Number:
Japanese Patent JP3708393
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that a shock against a nipped-in object cannot be reduced because the judgement for nipping the object in is delayed in a conventional nipping-in judging device and a conventional opening and closing device.
SOLUTION: Since piezoelectric sensors 5, 6 detecting a secondary differential value (acceleration) for given displacement time are provided on a window frame 3 and a visor 4 of a power window 1, nipping-in of the object 20 can be judged quickly, and a shock against the object 20 can be reduced.
