Definitions

  • This invention relates to motor vehicle window regulators, i.e. to mechanisms for raising and lowering the windows of motor vehicles.
  • window regulator Many different types are known and reference should be made to, for example, British Patent Specification No. 1198364 which shows cable-operated window regulators, cord and pulley-type window regulators and arm and segment-window regulators.
  • each of these different types of window regulators has disadvantages, particularly as regards providing adequate guidance for windows which have to be moved upwardly and downwardly along non-linear paths and as regards meeting packaging requirements either when the regulators are to be fitted within narrow doors or when the distance
  • freedom to locate the electric motor at any convenient location 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.
  • 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 connected to the slider element and means on the lever for attachment to a vehicle window such that, upon movement of the slider element along the guide track, corresponding movement of the lever is effected ro raise or lower the vehicle window.
  • 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 lever 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 lever 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 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.
  • the auxiliary lifting arm 11 is provided with a stud or roller 15 engaged in a channel in a glass carrier (not shown) centred on line 9.
  • 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) centred on line 8 and fixed to the door.
  • a guide (not shown) centred on line 8 and fixed to the door.
  • 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 conveniently 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 British Patent Specification No. 1091066.
  • Drive of the cable is effected by means of a motor/gearbox unit 19 and the cable terminates in an end formation 20 (Figure 2) which functions as a slider element within the plastic extrustion 17.
  • the end formation 20 is formed as a metal pressing attached to the cable 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 indicated) 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 10 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 lifting arm 11 while the auxiliary lifting arm 11 is pivoting in a clockwise direction about its pivot 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) centred on line 9 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 (not upward) movement of the studs or rollers 15 and 23 are the same.
  • the vehicle window is thus guided during its downward movement, being supported at two spaced positions by the arms 10 and 11, so that stable movement of the window is obtained. It is to be noted that, because the position at which the cable is attached 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 cable.
  • the auxiliary lifting arm 11 will move from a position in which the pivotal connection 12 between the two arms is at a location Ll to a location L2.
  • the end formation 20 of the cable moves from location 13 to location L4 and the stud or roller 23 moves from location L5 to location L6.
  • the window thus moves approximately 30% further than the cable and, for a door design in which glass travel is to be maximised, this will be an important consideration.
  • the motor 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 srelatively thick item, at any convenient location is again an important design consideration and enables an electric regulator to be used in circumstances in which there might otherwise be no possibility of locating an electric motor between the vehicle door panels without fouling the glass.
