Conventionally, this type of safety device has been equipped with a photoelectric switch consisting of a light-emitting element and a light-receiving element attached to the glass launch channel as a detector that stops or moves the movable window downward when an obstacle is inserted into the window frame. Known (Jitsukai 60-42879
However, when attaching the safety device to a glass launch channel, the width of the channel must be widened or a convex area capable of accommodating each element must be provided in order to secure installation space for the light-emitting element and light-receiving element, so the appearance around the window must be adjusted accordingly. affect. In addition, since it is located in a location that is easily exposed to outside air and rainwater when the door or window is opened, it may emit light,
Each element must be installed so as to be airtightly sealed without impairing the light receiving function, and it is particularly difficult to construct a watertight structure to prevent rainwater from getting on the harness that runs along the glass launch channel. .

Problems to be solved by the invention This invention maintains the flat surface shape without compromising the appearance of the car, and can be easily installed to protect the light emitting and light receiving electrical components and wiring system from outside air, rainwater, etc. An object of the present invention is to provide a safe drive control device for a vehicle power window.

Means for Solving the Problems In the vehicle power window safety drive control device according to the present invention, when the beam line is blocked by an obstacle, the reversible motor of the window regulator that is in the process of lifting the window glass is stopped. Alternatively, the emitter and receiver for beam line formation, which can be rotated in the opposite direction, are positioned inside the mounting points for vehicle interior accessories arranged around windows such as pillar inner panels and seatbelt upper holders, and are placed on the vehicle body side. It is constructed by equipping the

Function: In this vehicle power window safety drive control device, the mounting position and space for the emitter and receiver are secured by the vehicle interior fittings around the window, so the appearance of the vehicle body can be maintained while maintaining the flat surface type. Not only can you install the emitter and receiver without making major changes, but you can also protect them from outside air and rainwater with a simple mounting structure.In addition, the harness of the emitter and receiver can be easily installed along the vehicle body panel to reliably isolate them from rainwater. Be able to wire.

Embodiments The following description will be made with reference to the accompanying drawings.

This vehicle power window safety drive device operates when an obstacle exists between the window sash or the glass launch channel and the movable window glass, the movable window glass 1 shown in FIG.
It is equipped to drive and control a reversible motor (not shown) of a regulator that moves up and down 2, and the means for detecting obstacles is a light projector 3 that emits light and a light receiver 4 that receives the light. Beamline 5 is applied. The beam line 5 is formed on the inside of the vehicle so as to pass in a substantially horizontal direction slightly below the top dead center where the window glasses 1 and 2 move upward.

The transmitter 3 and the receiver 4 are of a transmission integral type, and are attached to the front pillar 6 and the rear pillar 7, respectively, as shown in FIGS. 2 and 4, so that each side window glass 1, It is equipped to form two beam lines 5. Also, the floodlight 3
As shown in FIGS. 3 and 5, the light receiver 4 is located inside the pillars 6, 7 or in the recesses of the pillars 6, 7, and the pillar inner panels 8, 9, which are interior accessories for the vehicle, cover each pillar 6, 7. The panels 8 and 9 are mounted on the vehicle body side around the window by being housed inside the mounting locations of the panels 8 and 9 so that they cannot be seen from the outside. It is sufficient to form small openings 8a, 9a in each pillar inner panel 8, 9 through which light from the beam line 5 passes, corresponding to the mounting positions of the emitter 3 and receiver 4. 9 can be kept in a flat surf ace shape.

The emitter 3 and receiver 4 are connected to a drive switch (not shown) placed on the armrest on the driver's seat side or on the armrest on each door side and a reversible motor for each window glass using a harness (not shown).
The harnesses from the emitter 3 and receiver 4 are wired between the pillars 6, 7 of the vehicle body and the inner panels 8, 9, and are electrically connected from the door hinge to the inside of the door panel. It is connected to form a control circuit with the reversible motor of the regulator. In this control circuit,
As will be described later, a controller unit 10 is connected to drive and control a reversible motor of the window regulator.

The controller section 10 operates to move the window glasses 1 and 2 up and down in accordance with the operation of the drive switch when the light receiver 4 receives the beam line 5 from the projector 3. On the other hand, if the beam line 5 is blocked by some obstacle, even if the drive switch is operated to move the window glass upwards, the reversible motor is stopped or the window glass is controlled to move downwards from the stopped position. The control circuit is assembled to at least stop the upward movement of the cylinder. The reset is preferably set to be performed when the interruption of the beam line 5 is stopped or when the pressing operation of the drive switch is stopped. Further, the circuit may be configured so that it does not operate when the drive switch is immediately operated to the lowering side.

In this vehicle power window safety drive control device, when the drive switch is pressed to move the movable window glasses 1 and 2 upward, a person's hand, neck, etc. When the beam line 5 is interrupted by an obstacle, the reversible motor of the window regulator is stopped or moved downward to close the movable window glass 1,
2 from no further upward movement, it can be operated to avoid obstructions being caught between the window sash or the glass launch channel. Therefore, not only can the power window function sufficiently as a safety device, but also small openings 8a and 9a can be formed in the inner panels 8 and 9 of the car interior fittings since the emitter 3 and receiver 4 are installed on the vehicle body side around the window. It can be installed on the inside of the attachment point of car interior accessories by deforming to the extent that it is formed, and by wiring the harnesses of the emitter 3 and receiver 4 to the car body side, it is possible to wire them so that they do not come into contact with rainwater, etc., so the car body side can be completely flushed It can be assembled and equipped extremely easily while maintaining the Tsushiyu Surf Ace shape.

In addition, in the above-mentioned embodiment, a case was shown in which both the window glasses 1 and 2 were controlled by beam lines spanning the front and rear sides of the same side, but in the case of a sedan type, a hard top type In this case, the vehicle interior equipment such as the seat belt upper holder 11 is equipped with a light emitter and a light receiver that pair with each device attached to the front pillar or rear pillar, so that the driving of each window can be controlled. be able to. Further, for convenience of explanation, the window glasses 1 and 2 on one side have been described as an example, but it goes without saying that this can be applied to windows on both sides. Furthermore, the light receiver 4 can be formed compactly using optical fibers such as plastic fibers or glass fibers. It is best to place it at the back of the

Effects of the Invention As described above, according to the safe drive control device for a vehicle power window according to the present invention, the upward movement of the window glass is stopped at the beam line formed near the top dead center of the window glass, and the upward movement of the window glass is stopped, and conversely, the downward movement is stopped. Since it can automatically control the movement of the window, it is possible to prevent problems such as children getting their hands or neck caught, and it is possible to maintain the appearance of the area around the window in a flat surface shape so that the device can be installed without major changes.
