Definitions

  • the present invention relates to a window regulator device, in particular for the door of a motor vehicle of the type comprising a control pinion driven by a geared motor and meshing on a rack integral with at least one of the ends of two maneuvering arms with variable angularity as a function the position of the glass which is provided at its lower part with a slide in which ball joints are arranged at the ends of the arms which drive it.
  • the known conventional devices of this type are constituted by two arms of cut sheet metal, crossed and angularly articulated in their center in the manner of a pair of scissors, one of their ends of which is capable of sliding in a slide of the ice for the drive up or down thanks to a drive geared motor whose output pinion drives a sector-shaped rack disposed at the other end of one of the arms, this assembly being mounted on a plate allowing its fixing in the door at several points.
  • this kind of device requires adaptation to each different vehicle and even it requires designing two asymmetrical devices per type of vehicle so as to fit one in the right door, the other in the left door. It is obvious that the multiplicity of these creations increases the cost prices and the costs of inventory management.
  • This device comprises a control pinion driving a perforated transmission belt tensioned by two first toothed return pulleys, and forming a triangle by the addition of a third pulley, belt made partially rigid by two rails articulated in the manner of a compass around one of the deflection pulleys so that, associated with the third flexible side, they constitute an assembly which is both homogeneous and foldable, capable of being successively folded for its easy introduction into the door and to be redeployed for its final positioning.
  • This device overcomes certain disadvantages but creates others because if the flexibility of one of the sides facilitates the introduction into the door, this has the disadvantage of constituting an articulated and non-compact assembly which, although it does not require platinum, requires the provision of several fixing points intended to stiffen the assembly and tighten the belt after introduction into the door.
  • the object of the present invention is to remedy all the aforementioned drawbacks of the two known types of window lifters by offering a compact and universal assembly, of easy handling and of extremely light weight.
  • a window-lifting device in particular for the door of a motor vehicle of the type comprising a control pinion driven by a geared motor and meshing on a rack integral with at least one of the ends of two maneuvering arms with variable angularity in function of the position of the glass which is provided at its lower part with a slide in which ball joints disposed at one of the ends of the arms which drive it characterized in that the two operating arms are arranged radially in relation -.
  • the window-lifting device shown in the figures generally comprises a control box 1 acting as a plate, on the periphery of which are guided, by means of a slide 2, the two radial arms 3 and 4 , driven in an angular debate, alternately following the arrows F1-F2, around the housing 1 by at least one flexible rack 5 perforated and secured to said arms 3 and 4.
  • a control pinion 6 driven by a geared motor 7, and on which it meshes through its perforations to be driven and thus cause the angular movement of the arms 3 and 4 at the free ends of which is arranged a ball joint 8 able to slide in a slide (not shown) arranged at the bottom of the glass (not shown) to drive it in an upward or downward movement in the vehicle door.
  • the gearmotor 7 is embedded in a housing 9 corresponding to its external shape and obtained during the same molding operation with the control unit 1, on the back of the latter (fig. 5).
  • the arrangement of the constituent elements of the gear motor 7 may also be carried out as described in patent application FR-A-2 386 924 of the applicant with the only difference that the lower casing of the gear motor is advantageously replaced by the control box 1.
  • the free ends 5a and 5b of the flexible rack 5 are joined to the arms 3 and 4 by means of the slides 2 which comprise means of connection with said rack 5.
  • the free ends 5a and 5b of the rack 5 form two S loops, which are guided in peripheral corridor portions 10 obtained by molding with the housing 1 and causing, simultaneously and respectively by pushing and pulling in a converging or diverging movement, the two radial arms 3 and 4 according to the arrows F1 or F2 .
  • the opposite movements of the arms 3 and 4 are precisely obtained thanks to the S-shape given to the belt 5 which has the effect of transforming a traction movement into a pushing movement or vice versa for one of the ends belt 5.
  • Figs. 2 and 3 respectively show in the upper or lower position of the window a window lifter device essentially different from the previous one in that the control pinion 6 drives two flexible racks 11 and 12, one 12 directly and the other 11 by via a pinion 13 secured to a return pinion (not visible) driven by the control pinion (6).
  • the free ends 11a and 12a of the flexible racks 11 and 12 form a guided loop in the peripheral passage portions 10 of the housing 1 and simultaneously drive the arms 3 and 4 by pushing or pulling in a converging or diverging movement.
  • FIGS. 4a and 4b essentially differs from the previous ones in that a double drive pinion 14, passes through the control box 1 and simultaneously drives two flexible racks 15 and 16 respectively arranged on either side of the box 1 and one of the ends of which free 15a and 16a of each rack 15 and 16 form a guided ball in the peripheral corridor portions 10 of the housing 1 and consequently drives the radial arms et4 to which they are connected.
  • the radial arms 3 and 4 used in the abovementioned embodiments, are obtained by cutting a thin sheet metal blank in which the slider 2 is shaped by folding and the free end 3a of which has an opening 17 in buttonhole shape obtained by cutting and capable of receiving the ball 8 by elastic snap-fastening.
  • the slider 2 is shaped by folding to obtain a U-shaped profile formed by folding and 90 ° folding of a central part 2a of the sheet metal blank at its part opposite to the free end 3a and constituting half of the U on the one hand and by folding and against 90 ° folding of the two ends 2b and 2c located on either side of the central part 2a and constituting the other half of the U of somewhere else.
  • the parallel branches 2a and 2b, 2c thus formed cover the outer rim 1a of the control unit 1, some 2b and. 2c being folded down against a lower edge 1b of the housing 1 and the other 2a also folded down to form a guide 2d capable of sliding in the peripheral corridor 10 thus acting as a rail.
  • the free part of the guide 2d is oriented towards the bottom 10a of the peripheral corridor 10 or rail and advantageously constitutes a comb whose toothing 2c corresponds and fits into the toothing 18 resulting from the axial and longitudinal cutting of the end of the any of the flexible racks 5, 11, 12, 15 or 16 according to the embodiment chosen, so as to secure one of the latter to the arm for its drive.
  • the combs 18 and 2e cannot escape one relative to the other during operation because the width of the corridor 10 corresponds approximately to the thickness of the rack.
  • the embodiment of the arms shown in FIG. 8 differs essentially from the previous in that the radial arms 3 or 4 are obtained by molding a plastic material during the same operation with the slide 2 and the guide 2d and comprise at their free ends 3a the ball 8 advantageously obtained material with the arm 3.
  • ribs 19 are obtained by molding on at least one of the faces of said arms 3 or 4.
  • a primer 20 is provided at their base so as to constitute a hinge.
  • the guide 2d can be attached to the slide 2, for example by providing on the back of the guide 2d, a tenon 21 able to engage in a mortise 22 formed in the slide 2 as shown in the embodiment of fig. 9 below described.
  • the embodiment of the arms shown in FIG. 9 differs essentially from the previous ones in that the radial arms 3 or 4 are constituted by a pin obtained from a filiform profile with a cylindrical section and whose head 23 in the form of a buttonhole is capable of receiving the ball joint 8.
  • the ball joint 8 has at its lower part a base 8a obtained integrally with it and provided with a groove 8b which snaps elastically into the abovementioned buttonholes.
  • the symmetrical branches 3b and 3c are bent at their free end along the same plane so as to constitute a hinge pin XX 'of which each part thus formed is capable of being introduced by elastic pinching in two corresponding bearings 24 and 25 formed on the side and on the other side of the slide 2 guiding the arms 3 or 4 on the periphery of the control box 1.
  • fig. 10 relating more particularly but not exclusively to the arms obtained by cutting a blank from sheet metal fig. 6 or by molding fig. 8, said arms are extended towards the center of the housing 1 to rotate around the same axis 26 disposed at said center so as to provide the arms 3 and 4 with more effective retention on the control unit 1.
