Title:
SIGNAL GENERATING MECHANISM OF EMERGENCY UNLOCKING DEVICE
Document Type and Number:
Japanese Patent JP2010043411
Kind Code:
A
Abstract:

To provide a signal generating mechanism of an emergency unlocking device which does not operate erroneously and has high reliability.

In the transmission mechanism of an emergency unlocking device, a slider pin 18 is assigned as a switch drive member, a microswitch 24 is disposed near a fixed seat position in the normal state of the slider pin 18, and the slider pin 18 is biased in the direction in which the actuator 25 of the microswitch is pressed. On the other hand, a spring member 26 is attached near the microswitch, the engagement part 28 of an actuator drive part 27 and the slider pin 18 is formed at the free end of the spring member. Normally, the spring member presses the actuator of the microswitch independently of the switch drive member, and when an emergency unlocking device is operated, the spring member is engaged with the slider pin 18, and is moved in the direction opposite to the biasing direction of the slider pin. Consequently, the microswitch 24 is switched to generate an emergency unlocking signal.
