Window lifter, particularly suitable for motor vehicles, with one in a guide movable threaded cable

The invention relates to a window regulator for sliding windows or the like, and in particular relates to one Window lifter suitable for motor vehicles, in which the window can be moved axially in a tubular guide Cable is connected to a drive, with a portion of the tubular guide parallel to the Fensterweg and then designed to run in an arch.

Window regulators of this type are known and have the special] Advantage that relatively little space is required for the installation of such window lifters and also the course of the

Cable routing and thus the cable from the window path parallel section apart, can be laid in practically any way, as it m with respect to the drive and the given spatial conditions appear appropriate. Here it is in order to achieve the lowest possible overall height arrive, generally required, the cable with the guide tube in connection with the parallel to the window path Section, so the active section, either above or below running in the direction of the drive unit redirect. Because every bendable cable has the smallest bending radius determined in practice, the usable stroke length is lost in the order of magnitude of this bending radius. It therefore inevitably results that the total height of the window regulator must be greater than the way the window between its closed and its fully open position.

In modern motor vehicle construction there is a tendency to equip the passenger compartment with ever larger glass surfaces.

This means that the ratio of the window height to the height of: the wall part of the body or the door box that contains the : the opened window is supposed to take up almost 1: 1. To get in

! In such cases it is necessary to lower the window completely

therefore necessary, the entire available height j of the wall part lying below the window opening to be used as the lifting height, so that in known window regulators with cable drive required space for the bending radius

of the cable is no longer available.

The invention is based on the object of remedying this to create and a window regulator which, for drive transmission, is an axially movable cable in a tubular guide used to train so that its height can be reduced and adapted approximately to the length of the window path and deflections of the tubular cable routing do not require any additional overall height.

This object is achieved according to the invention in that the path of a cable attached to the connection with the The driver serving for the window is not limited to the part of the tubular guide that runs parallel to the window path is, but extends at least partially over the area of the arch, and that the connection between the Carrier and the window a guide at right angles to the window Having window path. This makes it possible to use the area of the deflection of the cable for the stroke length to make, whereby the overall height of the window regulator is shortened accordingly.

In addition, however, the invention enables further advantages. It is achieved that when you close the Window, if it runs up against the seal at the top, and also laterally in the case of sloping window edges, and a higher torque requires the disk transport in the arch area of the

Kabelfürhung slows down and at the same time results in an increased closing pressure without increased torque. Furthermore , the inventive inclusion of the deflection of the cable in the active lifting area achieves an effective lock for the window in its closed position, since a downward force acting on the window does not contain any components for a transverse displacement of the cable required for opening. This lock is still large enough even if the window is slightly open to ventilate the vehicle.

It is also thanks to the step-down of the drive for the lifting movement of the window achieved by the action of components Possible in the beginning and end of the entire stroke with little effort, slight to medium icing the window easier to break loose than was the case with known window regulators.

According to the invention it is further provided that the part of the tubular guide running parallel to the window path is attached merges into an arc at both ends, and that the path of the driver contains at least parts of both arcs. By Such a design can be made use of all the advantages of the invention, regardless of whether in which direction the cable runs through when the window is opened.

window 2 provided, the frame box of the door i «itself extends from point A to B and is therefore not significantly higher than that which is decisive for the stroke length of the window Window height B-G. In the frame box of the door, a window regulator according to the invention is installed, which is a stationary Guide tube 3 for an axially movable pressure-resistant threaded cable therein, which is indicated by the dash-dotted line 4 is indicated. A hand crank 13 is provided as the drive for the cable 4, which is connected to the cable 4 engaged, not shown, drive pinion within the drive housing 14, the cable in the longitudinal direction the guide 3 moves.

The cable 4 is provided at or near its two ends with a driver 5, which passes through a longitudinal slot of the pipe 3 engages through (Fig. 3 »4) and to which a bolt or a roller 6 is attached, which in turn is in a link guide engages the lower edge of the window 2.

The link guide 7 or 7 ¹ can be connected directly to the lower edge 8 of the window 2 or attached to it via a window lifting rail 9. The latter type of embodiment is shown in FIG. 3, while FIG. 4 shows the version with a direct cross connection between the cable 4, which is even more favorable with regard to the overall height of the window regulator

and window bottom edge 8 shows, also for convenience a roller is provided for the link guide on the bolt 6

In this exemplary embodiment, the tube 3 has according to FIG Pig. 1 two active, namely the driver 5 for the window leading, sections, each consisting of a middle Section 3a parallel to Feneterweg and on top and There are subsequent deflections or bends 3b and 3c below. When the hand crank 13 is actuated clockwise move the driver 5 or the attached bolts 6 for a complete opening of the Window 2 in each case from point F to point G. During the initial movement to open it slides in the arch area 3b the bolt 6 at the same time within the link guide from point E to point L, then remains during the downward movement Stand over the distance 3a at point D of the link guide, namely as long as the guide tube is parallel runs to the window path and then wanders again from point D to point E as soon as the lower arch 3c is passed back within the Kivlissen guide 7.

As can be seen, in one such according to the invention Window lifter the stroke of the window is not limited to the rectilinear part 3a of the guide tube, but it becomes the

full height of the window regulator including the arches 3h and 5c for the hat). The invention thus creates a window regulator that fully opens a Sliding window is also permitted if the ratio of the height AB of the door box to the height B-G of the window is almost 1: 1 achieved. In addition, is advantageously just in the end areas of the lifting movement due to the Component effect of the backdrop in the area of the Arc curvature achieved reduction of the drive at the same torque on the hand crank 13, a greater force per unit of lifting height is available.

In the exemplary embodiment according to FIG. 2, the same parts are provided with the same reference numerals as in FIG. 1. ^{Here a sliding window 2 1 is} provided in a motor vehicle door 1 ', the width of which is smaller than in the first exemplary embodiment and which also has parallel side edges and is therefore safely guided over the entire stroke. It is therefore sufficient to have a so-called single-track window lifter with a cable 4 ¹ in a pipe guide 3 ¹ , the cable being connected to the lower edge 8 of the window via the link guide 7 according to the invention at only one point. Here, under otherwise the same conditions as in the first embodiment, the window 2 'is lowered by turning the hand crank 13 clockwise, the bolt 6 attached to the driver of the cable from point F to point G along the sections 3b, 3a, 3c of the pipe guide

wanders and at the same time within the backdrop 7 from point S to point D at the beginning of the movement and in the opposite direction when the open position is reached of the window moves.

Both in Fig. 1 and in Fig. 2, the window 2 is in drawn closed position, while the open position with lowered window with broken lines is indicated.

The design as a two-lane window regulator according to Fig. Is particularly suitable for wide windows or those which, as shown in Fig. 1, are only guided continuously on one side because of a sloping side edge. He can also always be used to advantage if the window is on both sides when lowering in area B-C runs out of the pane guide or such a pane guide on one or both sides at all is not present, such as B. in a convertible or a sports car.

Of course, the invention is not restricted to details of the exemplary embodiments described, but can for window lifters designed in various ways with cable drives by including curved parts of the Pipe guidance in the area of the usable stroke length can be used with advantage.
