Actuator of Passenger Protection Device
First Claim
1. An actuator of a passenger protection device, comprising:
- an actuating unit actuating the passenger protection device in response to reception of a first ignition signal; and
a manual cut-off unit being turned on or off to selectively disable or enable operation of the passenger protection device,the actuation of the passenger protection device by the actuating unit being inhibited when the manual cut-off unit is turned to disable the operation of the passenger protection device,wherein, when a second ignition signal having a communication format different from that of the first ignition signal is received, the actuating unit actuates the passenger protection device irrespective of a switched state of the manual cut-off unit.

Abstract
In an actuator of a passenger protection device, a sub ECU 200 is provided to actuate the passenger protection device in response to a normal ignition signal received from a main ECU 100 via an ignition communication line 2, and a manual cut-off switch 1 is turned on or off to selectively disable or enable operation of the passenger protection device. The actuation of the passenger protection device by the sub ECU 200 is inhibited when the manual cut-off switch 1 is turned to disable the operation of the passenger protection device. The actuator of the passenger protection device is characterized in that, when a collective-operation-specific ignition signal having a communication format different from that of the normal ignition signal is received, the sub ECU 200 actuates the passenger protection device irrespective of a switched state of the manual cut-off switch 1.

8. An actuator of a passenger protection device, comprising:
-
an actuate instruction unit outputting an actuate instruction signal to actuate the passenger protection device compulsorily; an ignition signal transmission unit transmitting an ignition signal in response to either detection of an impact to a vehicle or reception of the actuate instruction signal; an actuating unit actuating the passenger protection device in response to the ignition signal received from the ignition signal transmission unit; and a manual cut-off unit being turned on or off to selectively disable or enable operation of the passenger protection device, the actuation of the passenger protection device by the actuating unit being inhibited when the manual cut-off unit is turned to disable the operation of the passenger protection device, wherein the actuate instruction unit is provided to supply power to the actuating unit, and, when a power supply from the actuate instruction unit to the actuating unit is detected, the actuating unit actuates the passenger protection device irrespective of a switched state of the manual cut-off unit. - View Dependent Claims (9, 10)
