[0008]

In a vehicle equipped with a power window regulator, the regulator motor is not driven unless the ignition switch is turned to the Acc position or the ON position, so that the driver leaves other passengers in the passenger compartment. If the ignition switch is turned off and the door is closed, the key cylinder is operated to lock the door lock mechanism and the deadlock mechanism is restrained, the door can be opened even if the inside lock knob is operated from the passenger compartment side. It is also impossible to lower the window panel because the ignition switch is turned off even if the power window switch is operated.
Ventilation of the passenger compartment will not be possible at all.

Therefore, according to the present invention, the driver turns off the ignition switch while leaving the occupant in the passenger compartment, and locks the lock mechanism of all doors by operating the key cylinder, and puts the lock mechanism into a deadlock state by the deadlock mechanism. Even when the switch is operated in the vehicle compartment, the power window regulator is operated to lower the window panel to ventilate the vehicle interior.

[0010]

When the lock mechanism for all doors is locked by the key cylinder, the operation of an electrically driven actuator causes the movement of a knob lever that is locked and unlocked by being connected to an inside lock knob rod at a lock position. In a door equipped with a deadlock mechanism for restraining, and a power window for raising and lowering a window panel by driving a regulator motor by operating a power window switch, the deadlock mechanism restraining operation is performed in a control circuit of the power window regulator. An auxiliary circuit for driving the regulator motor by applying a battery voltage to the regulator motor by turning on an auxiliary switch is provided therein.

[0011]

[Function] Even if the ignition switch is turned off and the door is closed and the deadlock mechanism causes the lock mechanism to be in a deadlock state, the auxiliary circuit is closed by turning on the auxiliary switch in the vehicle compartment, and the regulator motor A window voltage can be lowered by applying a battery voltage to.

FIG. 2 shows an example of a power window regulator unit. A carrier plate 21 is fixed to the lower edge of the window panel 20, and the carrier plate 21 is engaged with a main guide rail 22 and moves up and down. It is like this.

A wire 24 is wound around the carrier plate 21 by a regulator motor 23 and is rewound.
25 are connected to each other, and by driving the regulator motor 23 forward and backward, the window panel 20 is moved to the main guide rail 22 and the front and rear guide rails 26.
It is designed to go up and down along.

FIG. 1 shows an example of the control circuit 30 of the regulator motor 23. Reference numeral 31 is an ignition switch, 32 is a power window switch, and 33 is a forward drive of the regulator motor 23, and the window panel 20 is raised. A side relay 34 is a down side relay that drives the regulator motor 23 in the reverse direction to lower the window panel 20.

The detection signals of the ignition switch 31 and the power window switch 32 are sent to the CPU 35, respectively, and the CPU 35 is in the state where the ignition switch 31 is in the Acc position or the ON position, for example, and the power window switch 32 is on the up side. 32
When it is turned on, the ignition switch 3
