Abstract

The drive mechanism slides a moving carrier, connected to a raising rail which engages the window pane, along a guide rail, to raise a window, esp. on motor vehicles. The raising rail is displaceable in the guide-rails lengthways direction, in relation to the moving carrier. The drive unit engages the raising rail. This rail may be connected to the moving carrier via a linear guiding system, pref. with guide rods, which is rigid in the face of tilt movements of the raising rail, relative to the moving carrier, in the plane of the window pane. A draw cable (34) of a cable drive can be attached to the raising rail.

Description

Window regulators, in particular for motor vehicles

The invention relates to a window regulator, in particular for motor vehicles, with a lifting rail engaging a window pane, one with the lifting rail connected, slidably mounted on a guide rail and a driver Drive for moving the driver along the guide rail.

In known window regulators of this type, the guide rails are rigid attached to the driver. The drive (crank drive or drive with electric motor) acts directly on the driver.

The stroke that can be achieved with the known window regulators corresponds to the maximum the distance between the upper and lower end positions of the driver on the Guide rail. The height of the window regulator measured in the direction of the guide rail is greater than the mentioned stroke, because at least the height of the driver is added comes. In those cases in which the window pane is not sufficiently guided laterally the carrier carrying the lifting rail must be adequately secured against tilting be. This requires a relatively large length dimension of the driver along the the driver against Anti-tilt guide rail. To the the height of the entire window regulator is correspondingly large overall height of the driver enlarged. The known window regulators of the type mentioned can therefore not be used when the amount of available installation space, for example the door shaft height of a motor vehicle door is in the area of the window height, there the height of the window regulator required for this stroke is greater than the height of the door shaft.

The object of the invention is to provide a window regulator of the initially mentioned type with increased stroke with constant height of the window regulator provide.

This object is achieved in that the lifting rail compared to the Driver is designed to be displaceable essentially in the longitudinal direction of the guide rail is and that the drive engages the lifting rail.

In the known window lifter mentioned at the outset, the lifting rail is in at least one of the end positions of the driver compared to the closest one upper or lower end of the window lifter offset inwards, which corresponds to the height of the driver and, if necessary, to the height of both ends of the guide rail provided parts (e.g. pull rope pulley) of the drive. According to the invention the lifting bar can be moved relative to the driver, also in the addressed one End position of the driver further to the nearest end of the window regulator. The stroke of the window regulator increases accordingly without its installation height increasing enlarged. Since the drive engages the lifting rail according to the invention, it ensures that the lifting rail also over its entire, extended lifting distance with the help of the Drive is movable.

For those cases where the window pane is sideways not is adequately guided, it is proposed that the lifting rail with the driver is connected via a guide, preferably a rod guide, which is rigid is opposite tilting movements of the lifting rail in the plane of the window pane relative to the driver.

Tilting moments of the disc can therefore be carried out via the lifting rail, the guide and the driver are taken from the guide rail, which in turn is in the Motor vehicle door is attached.

It is suggested that the direction of displacement in which the lifting rail is displaceable relative to the driver, to the longitudinal direction of the guide rail runs inclined, preferably at an angle between 5 ° and 200, best at an angle of about 100. This achieves with simple means that the window pane during part of the lifting movement in the longitudinal direction of the Guide rail and during the remaining part of the lifting movement, e.g. on the upper one End of the stroke, can be moved in the direction of displacement. This can be complicated too molded window panes are used in automobile doors.

As a simply structured yet mechanically stable guide a scissor linkage proposed with two scissor arms, each one end is articulated on the driver or on the lifting rail, the other end of which in an elongated hole of the retaining rail or the driver can be displaced and pivoted is mounted and articulated to one another in the region of their length centers are. It is useful if the driver with a parallel to the lifting rail Driver rail is formed and the ends of the scissor arms in the end regions the lifting resp.

the driver rail is mounted on the lifting or the driver rail which gives a sufficient base length of the linkage.

It is proposed that the driver with a tion the guide rail elongated, guided on the guide rail by means of sliding pieces Base plate is formed and that the driver rail at one of the longitudinal ends attached to the base plate. The elongated base plate ensures a sufficient stable guidance on the guide rail; the lifting rail held by the scissor linkage can rail between the driver and the other longitudinal end of the base plate without Crossing the scissor arms are moved, which allows the driver rail and to arrange the lifting bar on the same side of the scissor linkage.

To further improve the guidance of the driver on the guide rail it is proposed that at least one of the sliders has a longitudinal edge of the guide rail encompasses and rests against the side of the guide rail remote from the base plate.

In order to achieve the lowest possible depth of the window regulator and the window pane plane to reduce tilting moments as close as possible It is suggested to bring the guide rail to the lifting rail with little Train the distance from the base plate to be displaceable along this and if necessary cranked scissor arms on the sides of the lifting and to store the driver rail on the lifting or driver rail.

In an advantageous embodiment of the invention, the lifting rail preferably provided with a guide and sliding piece in the area of their mid-length, which rests on the guide rail. This achieves the lifting rail follows the course of the possibly curved guide rail exactly, resulting in ease of movement of the built-in window regulator contributes. Interspersed in a compact embodiment the guide and slider is an elongated hole in the base plate.

The usual motor-driven or hand-driven ones are used as the drive Window lift drives in question, e.g. linkage window lifter drive or threaded cable drive. Because of his However, a cable or Bowden cable drive is preferred for a particularly simple structure used with a pull rope attached to the lifting rail the window regulator, in particular the tilting action exerted on the curved guide rail and bending moments are particularly small when the pull rope is near the guide rail runs. It is therefore proposed that the lifting rail with a fastening part train that protrudes beyond the driver to the guide rail and a To attach the rope nipple of the pull rope to the fastening part. In a particularly simple one constructed embodiment is the fastening part penetrating the elongated hole of the driver designed as the guide and slider.

It is also proposed that the two leading to the cable nipple Rope pieces of the pull rope in the rope nipple by arranged close together Receiving openings occur which are parallel to the longitudinal direction of the guide rails Side surface of the cable nipple are formed. With the rope pull resp. Bowden cable drive can move the lifting bar up or down as far as possible until the upper or lower part of the pull rope leading to the rope nipple runs approximately perpendicular to the guide rail. With the cable nipples of known window lift drives the two pieces of rope occur on the radial end faces of an elongated, cylindrical, a cable nipple parallel to the guide rail. It decreases accordingly the maximum stroke that can ideally be achieved with a given deflection roller arrangement the axial length of this cable nipple. Around Stroke reduction to is to avoid, proposed according to the invention that the two leading to the cable nipple Rope pieces of the pull rope in the rope nipple by arranged close together Receiving openings occur which are parallel to the longitudinal direction of the guide rails Side surface of the cable nipple are formed.

The invention is explained below using an exemplary embodiment. 1 shows a front view of a window regulator according to the invention; Fig. 2 shows a side view from the left of the upper part of the arrangement according to FIG. 1 on an enlarged scale; 3 shows a side view similar to FIG. 2 of the lower part of the arrangement according to FIG. 1; FIG. 4 shows an enlarged sectional view of the arrangement according to FIG. 1 in section the line IV-IV; FIG. 5 shows a detailed section of the arrangement according to FIG. 1 in section along the line V-V and FIG. 6 shows a detail section along the line VI-VI.

1 to 6 show a built-in in a motor vehicle door Window lifter 10 with which a window pane 12 indicated in FIG. 1 is raised and can be lowered again.

In the side views of FIGS. 2 and 3 is indicated by dash-dotted lines Line indicated a door inner skin 14 to which the window regulator 10 is attached is.

To move the window pane 12, the window lifter 10 engages with it a lifting rail 16 on the lower transverse edge of the window pane 12 at. The lifting rail 16, in turn, is via a scissor linkage 18 with a driver 20 connected, which in turn is displaceable on a guide rail 22 in the longitudinal direction thereof is appropriate. The guide rail 22 is at its ends with end plates 24 and 26 and screwed to the door inner skin 14 via these plates 24, 26. To move the window regulator, a Bowden cable drive 28 is provided, which in Fig. 1 is only indicated schematically. A drive unit 30 can also be seen a cable drum 32, which either by means of a hand crank, not shown or an electric motor can be rotated in the direction of the double arrow A. One around the rope drum 32 looped pull rope 34 is in a closed loop guided over two pulleys, of which a pulley 36 on the lower in Fig. 1 End plate 24 and the other deflection roller 38 are rotatably mounted on the upper end plate 26 is.

Between the drive unit 30 and the lower or

upper end plate 24 or 26 is the pull rope through each a Bowden cable sleeve 40 led. A screw sleeve that accommodates the corresponding end of the Bowden cable sleeve 40 42 overlaps both lower end plate 24 and upper end plate 26 a screw-in thread 44 is attached to adjust the tension of the pull rope 34 to be able to. The drive connection between the pull rope 34 and the lifting rail 16 represents one to be dealt with in more detail below, attached to the lifting rail 16 Cable nipple 46 (see FIGS. 1 and 5). When the Bowden cable drive is actuated 28, the cable nipple 46 is moved back and forth between the pulleys 36 and 38, wherein he takes the lifting rail 16 and with it the window pane 12; like in will be explained in more detail below, that ensures the lifting rail 16 with the driver 20 connecting scissor linkage 18 on the one hand that the lifting rail 16 against lateral shift (i.e. against shift in direction the lower transverse edge 13 of the window pane 12) and against tilting in the window pane plane is secured and on the other hand that the lifting rail 16 over a longer distance can be moved than the driver 20, which leads to an increase in the stroke (distance between the end positions of the lifting rail 16) with the window regulator installation height unchanged (vertical distance c between the upper edge of the window regulator 10 inclusive the lifting rail 16 in its upper end position and the lower edge of the window regulator 10, i.e. the end plate 24).

The guide rail 22 is designed as an L-rail (see FIG. 4) and arched in accordance with the curvature of the window pane 12 (see FIGS. 2 and 3). With the the guide rail 22 is spot-welded to both end plates 24 and 26; in Fig. 1, a spot weld 48 is indicated. The lower end plate 24 is on one for stiffening Curved edge 50 with embossed nuts 52 for attachment to the door inner skin 14 trained. The upper end plate 26 is also in the area of the deflecting roller 38 provided with a bent edge 54, which like the screw-in thread 44 with the screw sleeve 42 carrying section 56 of the end plate 26 in FIG. 2 broken away is. A double bend to the door inner skin is used for fastening to the door inner skin 14 14 offset, provided with a fastening nut 58 fastening tabs 60 (see Figs. 1 and 2). The upper transverse edge of the guide rail 22 is denoted by 62.

In the area of this transverse edge 62, the end plate 26 is provided with a bent-up, provided as a stop for the driver 20 serving sheet metal tabs 64. A corresponding one also as a stop -serving sheet metal tab 66 is also on the lower end plate 24 formed.

As can be seen from FIG. 1, the longitudinal direction of the guide rail is 22 opposite the vertical (i.e. opposite the lower transverse edge 13 of the window pane 12 vertical, direction lying in the window pane plane B) inclined to form an angle d- of about 100.

The driver 20 consists of an elongated, along the guide rail 22 extending base plate 68 and one to the transverse edge 13 of the window pane 12 parallel driver rail 70, which is in one piece with in the area of its longitudinal center the lower end of the base plate 68 in FIG. 1 is connected. At the top of the Base plate 68 and at the lower end of the base plate 68 or at the lower edge of the Driving rail 70 in the area of its longitudinal center are two sliding pieces arranged, of which the left in Fig. 1 sliders 72 on the left Side of a leg 74 of the guide rail 22 rest and the respective right Sliders 76 on the right side of the leg 74.

As can be seen in FIG. 5, the sliding pieces 72 consist of the guide rail 22 bent sheet metal tabs 78 which are encapsulated with a plastic body 80. Due to the relatively large distance between the pairs of sliders at the ends of the driver 20, a correspondingly large guide base length of the driver is obtained 20 on the guide rail 22, so that larger ones in the plane of the window pane 12 horizontal tilting moments are transmitted from the driver 20 to the guide rail 22 can without fear of deformation of the components.

In Figs. 1, 4 and 5, another slider 78 can be seen which attached to the right longitudinal edge of the base plate 68 in about the middle of the length is and with a substantially L-shaped portion 80 in the area of the outer Kink edge of the guide rail 22, which is L-shaped in cross section, on both legs 74 and 75 of the guide rail 22 rests. The slider 78 is therefore used in addition to Sliders 72 and 76 as additional lateral guides, so that the sliders if necessary 76 can be omitted. In addition, the slide 78 Therefore, that the (horizontal) distance between the guide rail 22 and the driver 20 does not exceed a predetermined distance determined by the slider 78.

As can be seen in FIG. 4, the slider 78 also consists of a Sheet metal tabs overmolded with a plastic part and bent towards the guide rail 22 82 of the base plate 68. Finally, it is formed from the stamped sheet metal part Base plate 68 punched out a rectangular slot 84 through which a, The fastening part 86 of the lifting rail 16 still to be treated occurs (see FIGS. 1, 4 -and 5) The lifting rail 16 consists of one parallel to the driving rail 70 Base rail 88, at the two ends of which each have a U-shaped, the lower transverse edge of the window pane 12 encompassing fastening tab 92 attached is. Here, the Z-bracket 90 is spot-welded to the fastening tab 92 on the one hand and on the other hand attached to the base rail 88 via a screw connection 94. In the area of its mid-length above the base plate 68 and the guide rail 22 is the base rail 88 with one in FIG. 1 obliquely downwards parallel to the guide rail 22 extending flat projection 94 is provided to provide the mounting surface for the to enlarge said fastening part on the base rail 88.

The scissor linkage connecting the lifting rail 16 to the driver 20 18 consists of a first scissor arm 96 and a second scissor arm 98, which in Area of their length centers over the pivot pin 100 shown in FIG. 4 like scissors are hinged together. The end of the first scissor arm on the left in FIG. 1 96 is hinged to the left end of Mitnehrrerschiene 70, as is the left end of the second Scilerenarms 98 at the left end of the base rail 88. The two articulation points lie in the vertical direction (direction arrow B in Fig. 1) one above the other. The right end of the first scissor arm is in an elongated hole 102 at the right end the base rail 88 slidably and pivotably mounted, accordingly the right one End of the second scissor arm 98 in an elongated hole 104 at the right end of the driver rail 70. This type of guide ensures that the lifting rail 16 while maintaining their orientation (i.e.

the parallelism between driver rail 70 and lifting rail 16) relative to the driver 20 can be moved exactly in the vertical direction.

As can be seen from Figs. 1 and 4, the first and second scissor arms 96 and 98 both on the remote from the guide rail 22 Side of the driver rail 70 and the base rail 88 on the driver or

Base rail 70 or 88 attached. Furthermore, the ends of the scissor arms 96 and 98 cranked more or less strongly at their ends, so that the point of intersection (Pivot pin 100) of the scissor arms 96 and 98 on the one facing away from the guide rail 22 Side of the base rail 88 lies.

Accordingly, the lifting rail 16 is during all adjustment positions at a constant small distance to the driver 20 and to the guide rail 22, so that the distance between the parts guide rail 22, driver 20 and lifting rail 16 moments occurring during operation are relatively small. Fig. 1 shows with a solid line the upper end position of driver 20 and lifting rail 16 as well as FIG. 2; in Fig. 3 with a solid line and in Fig. 1 with a broken line Line are the respective lower end positions of driver 20 and lifting rail 16 indicated.

It can be seen that the vertical distance a between the base rail 88 and the driver rail 70 in the upper end position of the window lifter 10 is larger is than the corresponding distance b in the lower end position of the window regulator 10.

With a height c of the window regulator of approx. 50 cm the Difference between a and b approx. 5 cm. The stroke of the window regulator is around this 5 cm 10 enlarged compared to a window lifter, in which the lifting rail is rigidly attached to the driver is attached.

The arrangement as well as the construction of the fastening part 86 go from the Figs. 1, 4 and 5 emerge. With regard to the sectional view according to FIG. 4, it should be noted that with a dot-dash line those above the cut surface, therefore never visible, sections of the components are indicated.

The fastening part 86 consists of an approximately U-shaped fastening tab 86, the leg ends 106 of which each have a corresponding slot in the lifting rail 16 enforce and the to the remote from the guide rail 22 top of the Lifting rail 16 are bent over. In the from the fastening tab 105 and the Underside of the lifting rail 16 limited space, an insert body 108 is inserted, which in turn encloses the already mentioned cable nipple 46. To make the transfer to mitigate impacts between lifting rail 16 and Bowden cable drives 28, the Insert body 108 can be made of damping material, such as rubber.

As can be seen in FIGS. 4 and 5, they come to the cable nipple 46 leading two rope pieces 33 and 35 of the pull rope 34 on one to the longitudinal direction of the guide rail 22 parallel side surface 110 into the cable nipple 64.

The corresponding receiving openings are in the direction of the guide rail arranged directly next to each other. In Fig. 1 is both the upper setting the lifting rail 16 and thus the cable nipple 46 as well as, with dotted line, the lower setting of the cable nipple 46. Since the end points of the cable pieces 33 and 35 at the cable nipple 46 can lie directly next to one another, given the distance the pulleys 36 and 38 a large cable nipple stroke can be achieved.

The stability of the entire arrangement is increased by the fact that on the fastening part 86 sliding tongues 112 are injection-molded with which the lifting rail 16 is supported on the leg 75 of the guide rail 22. The pull rope 34 runs between Guide rail 22 and base plate 68.

Is the window regulator 10 (with the window open) in his lowest end position (indicated in Fig. 3 and in Fig. 1 with a broken line) and if the Bowden cable drive 28 is now actuated, the lifting rail will move 16 and the driver 20 together in the longitudinal direction of the guide rail 22 below Maintaining the distance b. It is because there is friction between drivers 20 and guide rail 22 due to the sliding pieces 72, 76 and 78 are relatively small and an increase in the distance b is generally increasing in this case Tension of the pull rope 34 counteracts. Only when the driver 20 in its upper Has reached the end position, the lifting rail 16 is moved away from the base rail 88, until the one shown in FIG. 1 is in the upper end position of the window lifter 10 Distance a results. Here, the lifting rail 16 does not move in the longitudinal direction the guide rail 22 but in the vertical direction A. This has the advantage of that the window pane at the end of its movement is approximately perpendicular to the corresponding Sealing strips is moved to. An upper stop for the window regulator 10 is generally not necessary, as the stop passes through the upper sealing groove of the Window pane 12 is formed.

The sequence of movements when opening the window is accordingly reversed. The already mentioned sheet metal tab 66 serves as a lower stop for the window regulator 10. As can be seen from FIG. 3, the driver 20 strikes against the sheet metal tab 66; the lowest position of the lifting rail 16 is then reached, if these in the area of the articulation points of the scissor arms 96 and 98 on the driver 20 got.

The lifting linkage 18 shown in the figures is designed symmetrically (Rod arms 96 and 98 of the same length as well as elongated holes 102 and 104), so that the lifting rail 16 can be displaced parallel to the driver rail 70 is, that is, performs a pure translational movement. However, should the angular position the lifting rail 16 relative to the driver rail 17 depending on the opposite side Change the distance, so the lifting rail 16 compared to the driver rail 70 is a combined Carry out shifting pivoting movement, so you have to use the scissor linkage 18 accordingly train asymmetrically. For this purpose, you can, for example, scissor arms of different lengths Insert 96 and 98; you can also use the two elongated holes 102 and 104, not like in fl. 1 shown parallel to one another, but rather inclined to one another. The combined displacement and swiveling movement achieved in this way can for reasons of space may be necessary or to adapt to special disc shapes or disc seal arrangements.

In order to facilitate the adjustment of the window regulator 10 during installation, the lifting rail 16 can opposite the driver rail 70 in the direction of the double arrow C, d. H. can be adjusted parallel to the lower transverse edge 13 of the window pane 12. As indicated in Fig. 1, this is a third slot 105 at the left end of the Lifting rail 16 is provided which, like the two other elongated holes 102 and 104 run in the longitudinal direction of the rails 16 and 70 which are parallel to one another. A pivot pin 107 attached to the left end of the scissor arm 98 passes through it the elongated hole 105. To this pivot pin 107 in a certain position within of the elongated hole 105 is one along the elongated hole 105 trending Adjustment screw 109 is provided, whose in Fig.

1 right end can be rotated in a transverse hole in pivot pin 107, but is fixed axially immovable and with its threaded portion 111 one from the Z-angle 90 protruding, provided with a corresponding internal thread tab 113 interspersed. When the adjusting screw 109 is rotated, it is consequently in the direction shifted the screw axis and with it the pivot pin 107. Accordingly the lifting rail 16 moves in direction C, since the two leading the rail Long holes 102 and 105 are parallel to each other. The elongated hole 105 can with the same The result is also attached to the driver rail 70 instead of the lifting rail 16- will.

If the elongated hole 105 is perpendicular instead of in the longitudinal direction of the rail to the longitudinal direction of the rail, you can see the inclination of the lifting rail 16 opposite adjust the driver rail 70, wherein the adjusting screw continues along the Elongated hole runs. If, in addition to that shown in Fig. 1, to the longitudinal direction parallel elongated hole 105 on the lifting rail 16, another elongated hole with adjusting screw attaches to the left end of the driver rail 70, the lifting rail 16 Adjust both in the longitudinal direction of the lifting rail and its inclination in relation to it the driver rail 70.
