Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to a window regulator that is most suitable for self-driving cars.

[Prior Art] Conventionally, as a window regulator for raising and lowering a wind panel (glass), for example,
The one described in Publication No. 80 is known.

This window regulator has a tape type structure in which a band-shaped tape is used as a lifting means for raising and lowering the window panel.

[Problem to be Solved by the Invention 1] As described above, the tape for raising and lowering the wind panel is made of synthetic resin and has a shape perpendicular to the glass surface of the window glass. Further, the rollers of the drive section for winding and feeding out the tape are provided at the top and bottom, respectively, and the roller axes are perpendicular to the glass surface of the window glass, so there is a problem that the drive section becomes large. Furthermore, the distance from the guide rail to the drive unit, that is, the length of the extension increases, making it difficult to achieve compactness. In particular, since the space for mounting inside the door is limited, if the amount of overhang is large, it may affect other Akebono parts, so mounting is not desirable from the viewpoint of performance.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a window regulator that can be made more compact by minimizing the amount of protrusion of the drive section.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a curved guide rail fixed to the inner panel of the door;
A carrier plate, on which the wind panel is attached, is slidable along the guide rail; and a carrier plate, which is provided approximately in the middle of the curved side of the guide rail, is capable of forward and reverse rotation by a desired driving means, and has a roller axis. It consists of a drive roller that is approximately parallel to the panel surface of the wind panel, and a belt-shaped drive tape that has one end wound around the drive roller in parallel in the winding direction and the payout direction, and the other end connected to the carrier plate. .

[Function] In such a window regulator, the drive roller is provided approximately in the middle of the curved side of the guide rail, and the roller axis of the drive roller is arranged approximately parallel to the panel surface of the wind panel, so that the overhang of the drive roller is fixed. is minimized, and the limited installation inside the door can be installed effectively with respect to space.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 3.

In the figure, reference numeral 1 indicates a guide rail of a window regulator 5 having rail portions 3, 3, and upper and lower mounting brackets 7, 7 are fixed to the inner panel 9 of the door.

The guide rail 1 is curved along the inner panel 9 of the door, and a main 11 rear plate 13 to which a window panel 11 (glass) is attached is slidably attached to the rail parts 3. Further, a drive roller 15 is fixed to the curved side of the guide rail 1.

The drive roller 15 is provided approximately in the middle of the guide rail 1. The roller axis W of the drive roller 15 is arranged approximately parallel to the panel surface 11a of the wind panel 11, and is attached to the take-out shaft 1a of the reducer 17, which decelerates and takes out the rotational assistance of the motor M serving as the drive means. has been done. The motor M is controlled by a hand switch (not shown) to freely rotate forward and reverse, and the motor axis Y is arranged almost parallel to the panel surface 11a of the wind panel 11, so that the protrusion ID is minimized. There is.

On the other hand, a band-shaped drive tape 19 is wound around the drive row 515 . The drive tape 19 consists of a first steel tape 21 wound around the center of the drive roller 15, and second steel tapes 23, 23 wound side by side on both sides of the first tape 21. There is. The first tape 21 is
After being set wider than the second tapes 23, 23 and extended along the rail body of the guide rail 1, and being transferred to the opposite rail body side via the upper guide roller 25, the terminal portion 21a is It is connected to the carrier plate 13.

The second tapes 23, 23 are extended along the rail main body, and after being swept to the opposite rail main body side via the lower guide rollers 27, 27, the terminal portions 23a are attached to the carrier plate 1.
It is connected to 3.

The upper guide roller 25 faces into the opening 29 of the rail body and is supported by a bracket 33 that is urged upward (upward in FIG. 3) by a biasing spring 31. bracket 3
3 is mounted and supported by a slidable coupling pin 37 within the range of a long hole 35 provided in the rail body. As a result, the first tape 21 is always urged upward, but tension is applied by the idle roller 25.

The guide rollers 27 and 27 on the lower side are connected to the opening 3 of the rail body.
facing downward by the biasing spring 41 (downward in Figure 3)
It is supported by a bracket 43 that is biased towards the bracket 43. The bracket 43 is mounted and supported by a sliding coupling pin 47 within a slot 45 provided in the rail body.

As a result, tension is applied to each of the second tapes 23, 23 by the guide rollers 27, 27, which are always urged downward. In this case, for example, as shown in FIG. 4, the extended end portion 211 of the first tape 21 is
It is connected to the carrier plate 13 via. Also, the second
The extended end portions 23a and 23a of the tapes 23 and 23 are connected to the connecting bin 48 via the guide roller 27 on the lower side,
It is also possible to use a means for engaging the tension spring 49 extended from the carrier plate 13 with the connecting pin 48. In this embodiment, one tension spring 4
At step 9, the tension of each tape 21 and 23 can be obtained simultaneously.

Note that 51 indicates a stopper that positions the wind panel 11 at the lowest position, and the lower side is attached to the bracket 7 so that it can come into contact with the lower end of the carrier plate 13.

In the window regulator configured in this way,
One drive tape pulls the carrier plate 13 up and down as the drive roller 15 rotates forward or backward. This results in
The wind panel 11 comes to move up and down along the guide rail 1. On the other hand, since the drive roller 15 that raises and lowers the wind panel 11 is arranged approximately in the middle of the curved side of the guide rail 1, the overhang ffi D f, t l can be suppressed to a small amount, and installation inside the door is limited within the space. It will fit compactly.

Further, since the drive tape 19 is made of steel, it can be obtained at a lower cost than a tape made of synthetic resin, and it is also lighter than a wire-type flexible wire, which is very favorable in terms of weight reduction.

[Effects of the Invention] As explained above, according to the window regulator of the present invention, the protrusion of the drive roller can be minimized, so it can be made more compact, and installation inside the door can take up limited space. can be effectively accommodated.
