Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a window regulator for a motor vehicle, and more particularly to a cape-driven window regulator.

Conventional technology Conventionally, a general ζ and 7-mm drive system has been used as a window regulator to adjust the opening and closing of automobile window glasses, but in recent years, due to the demand for lighter vehicle bundles, cable-driven wind regulators have been used. It is beginning to be used.

FIG. 4 shows an example of such a cable-driven wind regirator. A guide rail 51 is fixed to the inner panel 50 of the door of a KIJ car by a mounting leg 154G, and the edges 511L and 51b of the guide rail 51 are provided as a clamping piece 52L that protrudes from the support 52 of the windshield 55.
, by holding the slider by 52b,
The support 52 is slidably engaged with the guide rail 51, passes through the groove of the kite rail 51, and connects the cable deflection pulleys 56, 57 and the motor 58 provided near the upper and lower ends of the guide rail. A cable 53 is stretched to form a roof between the driven cable drive door and the ram,
A projection (not shown) is fixed to the end portion of the cable, and this fixed portion is engaged with a locking portion 510 provided so as to protrude from the window glass support 52 into the groove of the guide rail 51. Wind legierators and the like are known.

Since the window glass of a car is constantly exposed to irregular and complex forces such as in the front-rear direction, left-right direction, and [g1 direction] when the car is raised and lowered, the window glass is constantly and irregularly displaced. As a result, the friction at the sliding part between the guide rail 51 and the window glass support 52 and between the edge of the window glass and the door guide sash increases, causing the drive motor to become sluggish. There were drawbacks such as overload or overload.

Such a tendency is particularly remarkable when the window structure is a sash-less tie 1.

SOLUTION MEANS The present invention has been made to eliminate the drawbacks of the conventional wind-regi island rake device. lb and the guide rail i

In Father's example, the guide rails, pulleys, cable drive drums, etc. were attached directly to the inner panel of the automobile door.・Of course, it is also possible to attach the door to the inner pile of the door.
It is. It goes without saying that the cable tensioner is not limited to the one in the upper row, and any known cable tensioner can be used.

Effects This window regulator, which is a descendant of the present invention, has a structure in which the windshield is supported and guided by two kites spaced apart from each other, and the tension of the drive group is provided on the windshield support. It has a structure that converts driving force in the vertical direction via dynamic slides* (pulleys for raising and lowering), so it can provide strong support against vibrations and can significantly reduce operating force, making it the first in history. By adopting guide rails with opposing V-shaped cross sections, sr3MiL can withstand irregular vibrations and forces in all directions such as left, right, diagonal, etc.
Since this can be done without causing any positional displacement, it is possible to move up and down on the same trajectory extremely smoothly and accurately. Therefore, it is possible to prevent overloading of the drive system of the window regulator, and also to extend its life.
This is particularly noticeable.
