SPECIFICATION
Metro (Registered trade mark) electric regulator This invention relates to motor vehicle window regulators, i.e. to mechanisms for raising and low ering the windows of motor vehicles.
Many different types of window regulator are known and reference should be made to, for exam ple, British Patent Specification No. 1,198,364 which shows cable-operated window regulators, cord and pulley-type window regulators and arm and segment-window regulators. However, each of these different types of window regulators has dis advantages, particularly as regards providing ade quate guidance for windows which have to be moved upwardly and downwardly along non-linear paths and as regards meeting packaging require ments either when the regulators are to be fitted within narrow doors or when the distance of travel of the window is to be maximised.
In order to achieve economics as regards fuel consumption and to increase interior space/overall size characteristics, it is important not only that the overall thickness of a vehicle door should be min imised whilst retaining adequate strength charac teristics but also that the weight of the vehicle door should be kept as low as possible. In addi tion, in the case of manual window regulators, it is desirable that a smooth winding action should be obtained. As far as electric window regulators are concerned, freedom to locate the electric motor at any convenient location, for example adjacent the door latch, can be an important design feature simplifying overall design of a door or enabling a standardised electric regulator design to be used in a number of different doors.
It is accordingly an object of the present inven tion to provide an improved form of window regu lator having the various advantageous features 105 described below.
According to one aspect of the present invention there is provided a motor vehicle window regulator including a guide element for attachment to a door component, a slider element movable along a guide track afforded by the guide element, a cable attached to the slider element, operating means for effecting linear movement of the cable to move the slider element along the guide track, a lever con nected to the slider element and means on the le ver for attach ment to a vehicle window such that, upon movement of the slider element along the guide track, corresponding movement of the lever is effected to raise or lower the vehicle window.
An important advantage of this arrangement as compared with a conventional cable-operated regulator as described in British Patent Specification No. 1,198,364 is that the interposition of a lever between the cable and the window attachment means can be arranged to provide that, in at least a portion of the travel of the cable, the distance moved by the window can be greater than the distance moved by the cable such that, if desired, the total distance of travel of the window can be greater than the height of the guide element. This 130 can be of particular advantage if the vehicle designer wishes to maximise the size of the glass in relation to the overall height of the door.
According to a second aspect of the present in- vention there is provided a cable-operated window regulator for a motor vehicle in which lever means.are provided for obtaining a linear gain, i. e. lever means are provided whereby for at least a portion of the travel of the window, the distance moved by the window is greater than the distance moved by the cable.
The [ever means may comprise a pair of levers, the levers being pivotally interconnected intermediate their ends to provide a cross-arm lever system with one of the levers pivotally connected to the slider element and the other]ever pivotally connected at its one end to the guide element.
The lever pivotally connected to the slider element is hereinafter referred to as the main lifting arm and is provided at its one end with means for connection to a glass carrier. The slider element is preferably in the form of an end formation for the cable and is arranged for movement within a guide element in the form of a plastic tube carried by a guide rail to which the other lever, hereinafter referred to as the auxiliary lifting arm, is pivotally connected.
The invention will now be described by way of example with reference to the accompanying drawing which illustrates one form of electrically operated window regulator for a motor vehicle.
The window regulator includes a main lifting arm 10 and an auxiliary lifting arm 11 pivotally connected at 12 to provide a cross-arm structure.
The auxiliary lifting arm 11 is pivotally mounted at 13 on a support rail 14 attached to the door frame (not shown) by suitable fixing brackets. The auxiliary lifting arm 11 is shown in the drawing in one of the limiting positions of its pivotal movement i.e. in the position which it occupies when the window is fully closed. At its upper end, the auxiliary lifting arm 11 is provided w1th a stud or roller 15 engaged in a channel in a glass carrier (not shown). The main lifting arm 10 is also shown in the position which it occupies when the window is fully closed and, at its lower end, it carries a stud or roller 16 which engages in a horizontal channel in a guide (not shown) fixed to the door. Thus, as the auxiliary lifting arm 11 moves about its pivot 13, the stud or roller 16 will move horizontally within its channel.
The support rail 14 is formed as a metal pressing and carries a generally C-section plastic extrusion 17 which forms a continuation of a plastics tube 18 within which a drive cable is disposed. The drive cable is conieniently a helically wound wire cable to which a brush-like layer of short elastic fibres is applied so as to obviate any noise generation and obtain a smooth drive action, as described in Brit ish Patent Specification No. 1,091,066. Drive of the cable is effected by means of a motor/gearbox unit 19 and the cable terminates in an end formation 20 which functions as a slider element within the plastic extrusion 17. The end formation 20 is formed as a metal pressing attached to the cable 2 GB 2 144 798 A 2 and includes a pair of parallel arms which pass through an aperture in a plug 21. The ends of the arms are folded over (as indlcated) to engage against a washer 22 which serves to retain the plug 21 within an aperture in the main lifting arm 10. The arrangement is such that the plug 21 is free to rotate within the aperture in the lifting arm so that, as the cable is driven by means of the motor/gearbox unit 19, the slider element 20 will be displaced along its guide track afforded by the plastic extrusion 17 and the main lifting arm 10 will be caused to pivot in an anti-clockwise direction about its pivotal connection 12 to the auxiliary lift ing arm 11 while the auxiliary lifting arm 11 is pi voting in a clockwise direction about its pivot 80 mounting 13.
The main lifting arm 10 is provided at its upper end (as shown) with a stud or roller 23 engaged in a channel in a glass carrier (not shown) and the geometry of the system is such that, as the two arms 10 and 11 move relative to one another, the rates of downward (or upward) movement of the studs or rollers 15 and 23 are the same. The vehi cle window is thus guided during its downward movement, being supported at two spaced posi tions by the arms 10 and 11, so that stable move ment of the window is obtained. It is to be noted that, because the position at which the cable is at tached to the main lifting arm 10 is spaced from the point at which the arm 10 is connected to the glass carrier, the rate of travel of the glass carrier will not be the same as the rate of travel of the ca ble. Thus the auxiliary lifting arm 11 will move from a position in which the pivotal connection 12 between the two arms is at a location L1 to a loca tion L2. During this travel, the end formation 20 of the cable moves from location L3 to location L4 and the stud or roller 23 moves from location L5 to location L6. The window thus moves approxi mately 30% further than the cable and, for a door design in which glass travel is to be maximised, this will be an important consideration.
With the particular construction shown, the mo tor 19 is located at a substantial distance from the rail 14, i.e., adjacent the vehicle door latch. This freedom to locate the motor 19, which is a relatlvely thick item, at any convenient location is again an important design consideration and ena bles an electric regulator to be used in circumstan ces in which there might otherwise be no possibility of locating an electric motor between the vehicle door panels without fouling the glass.
