DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Example 1. FIG. 1 is a schematic configuration diagram of a first embodiment of a power window device according to the present invention. In the figure, reference numeral 1 is a motor, which is built in a drive mechanism section 4 provided inside the door 3, and the window glass 2 is raised (UP) or lowered (DOWN) by its driving force.
A power window operation switch (switch) 5A turns on and off the power to the motor 1. The power window operation switch 5A is a seesaw type switch having a polarity switching mechanism, and when connected to the motor 1, the motor 1 rotates forward when the motor 1 is tilted to one side and the motor 1 when the motor 1 is tilted to the other side. Rotates in reverse.

Reference numeral 6 is an ignition switch. Reference numeral 7 denotes an auxiliary switch (switch), which is connected in parallel to the ignition switch 6. This auxiliary switch 7
It is a push button type that turns on only while it is pressed,
The power window operating switch 5A is activated when the ignition switch 6 is off. That is, the window glass 2 can be opened and closed by operating the power window operation switch 5A while pressing the auxiliary switch 7. Reference numeral 8 denotes a battery that supplies power to each part of the vehicle.

The drive mechanism section 4 (including the motor 1) and the power window operation switch 5A are constituent elements for controlling the window glass 2 of the door 3, and similar constituent elements are provided for other doors, respectively. Power is supplied from the battery 8 via the ignition switch 6 and the auxiliary switch 7. Here, FIG. 2 is a perspective view showing the appearance of the power window operation switch unit.
In this figure, each of 5B to 5D is a power window operation switch for up / down a window glass (not shown) of another door. Each of the power window operation switches 5B to 5D is activated by pressing the auxiliary switch 7 even when the ignition switch 6 is off, like the power window operation switch 5A.

A push-button type switch is used as the auxiliary switch 7, but in addition, a rotary type switch that is turned on by rotating, a slide type switch that is turned on by sliding, or an engine is used. A method of turning on by inserting a key may be used.
FIG. 3 is a perspective view showing a power window operation switch unit employing a rotary auxiliary switch 9, and FIG. 4 is a power window operation switch employing an auxiliary switch 10 that is turned on by inserting an engine key. It is a perspective view which shows a part.

Also. Although the seesaw type is adopted as the power window operation switches 5A to 5D, the lifting type may be used. When a lifting type power window operating switch is adopted, a sliding type having an operating direction different from the operating direction of the power window operating switch is suitable as the auxiliary switch. By making the operation directions different from each other, erroneous operations can be reduced.

Example 2. In the first embodiment, the power window operation is limited by the combination of the ignition switch 6 and the auxiliary switch 7. However, in the second embodiment, the ignition switch and the seat belt detection switch 50 shown in FIG. , AT (automatic transmission) shift position detection switch (parking "P" position detection) 51, side brake detection switch 52, foot brake detection switch 53, or engine rotation detector 54 in combination to limit power window operation. It's something that you do.

Here, FIG. 5 shows a driver's absence detection pattern. In FIG. 5, the meaning of each pattern is as follows. (A) Pattern 1: The absence of the driver is determined based on the output signal D of the engine rotation detector 54, and the power window operation is invalidated. As an effect, even if the driver is absent and the child is mischievous and the ignition switch is turned on while the engine is stopped, the power window operation can be prohibited (under the condition that the engine is not started).

(B) Pattern 2: The absence of the driver is judged based on the output signal E of the seat belt detection switch 50, and the power window operation is invalidated. As an effect, it is possible to prohibit the power window operation by the mischief of a child while the driver is absent (the seat belt is removed). Further, wearing of the seat belt can be promoted.

(C) Pattern 3: Engine rotation detector 5
Based on the output signal D of No. 4 and the output signal E of the seat belt detection switch 50, the absence of the driver is determined and the power window operation is invalidated. As an effect, the power window operation by the mischief of the child can be prohibited while the driver is absent (the engine rotation is zero and the seat belt is not worn). In addition, it is possible to avoid the inoperability of the power window due to a failure.

(D) Pattern 4: Output signal A of shift position detection switch 51 and side brake detection switch 52

As an effect, the power window operation by the mischief of the child can be prohibited while the vehicle is stopped. Normally, it is impossible for a child to pinch a part of the body such as a hand or a neck on a window glass while the foot brake is stepped on. A normal power window operation can be performed by stepping on the foot brake during normal traveling or while stopped.

(E) Pattern 5: Output signal A of shift position detection switch 51 and side brake detection switch 52
The absence of the driver is determined on the basis of the output signal B of 1 to disable the power window operation. However, the output signal D of the engine rotation detector 54 determines that the driver is in the vehicle, and the power window operation is enabled. As an effect, in addition to the effect of the pattern 1, the operability in the normal case can be improved by prohibiting the power window operation only while the vehicle is stopped.

(F) Pattern 6: Output signal A of shift position detection switch 51 and side brake detection switch 52
The absence of the driver is determined on the basis of the output signal B of 1 to disable the power window operation. However, the output signal E of the seat belt detection switch 50 determines that the driver is in the vehicle, and validates the par window operation. As an effect, in addition to the effect of the pattern 2, by prohibiting the power window operation only while the vehicle is stopped, the operability in the normal case can be improved.

In the second embodiment, it is assumed that the absence of the driver is detected according to the pattern 2. FIG. 6 is a schematic configuration diagram of the power window device according to the second embodiment. In this figure, each of 15 to 18 is a motor, and among them, the motor 15 is UP / UP of the window glass of the driver side door.
