Definitions

  • the present invention relates to window winders for motor vehicles.
  • window regulators Most of the usual window regulators have a construction which, to a large extent, is adapted to the particularities of the vehicle door which has to be fitted. In the same vehicle, depending on whether the door is at the front or rear, or whether it is on the right or on the left, different basic components for the window regulators must, most often, be provided . Likewise, in general, the basic structure of a window regulator must be established according to the drive mode, manual or by electric motor. Such specialization in the construction of window regulators obviously leads to manufacturing complications and increased costs.
  • window regulators with symmetrical crossed arms such as that described in application EP-A-0 018 914, in the name of the applicant, which comprises a hinge nut carried by a slide guided in an essentially vertical slide whose axis coincides with the axis of symmetry. Due to the symmetry of the arms, the window lifter can, without particular difficulty, be mounted either on a right door or on a left door.
  • the slider and the slide of the known window lifter are clearly different, depending on whether the drive is carried out manually, in which case the slide is a tubular sheath for guiding a flexible control cable, or else by means of an electric motor, the slider then constituting a nut engaged with a screw rotated by the motor.
  • the object of the invention is to provide a window regulator which is almost completely trivialized, that is to say the basic components of which can be used as such for equipping any vehicle door.
  • the invention relates to a window lifter of the type described in EP-A-0018914, comprising at least one inclined arm pivotally mounted at an intermediate point of its length, on a hinge pin carried by a slide which is guided longitudinally in a U or C profile forming a substantially vertical slide and which carries a rack engaged with a drive pinion through a lateral opening of the U or C profile, the two ends of the arms being guided in the slides perpendicular to the axis of the slide, which are respectively fixed to the bottom of the glass and fixed, the fixed slide defining a central line on either side of which the arm can move, which is characterized in that the bottom of the vertical slide profile has a flat or cutout at the right of which the material is deformed towards the inside of said slide so as to form the bottom wall of a housing open laterally by t and other of said wall, and to delimit an opening through which a pinion forming part of a drive module, assembled to the slide is mounted inside the profile in the housing and engaged with the rack.
  • This arrangement defines a basic mechanism for the window regulator with which a drive module can be assembled, quite simply, meeting any particular conditions, particularly with regard to the configuration of the vehicle door, the position of the seats and the mode of control, manual or engine-driven, of the window.
  • the rack pinion is introduced from the rear through the mounting opening in the bottom of the profile of the slide.
  • the drive module may include a housing or an assembly plate which can be pressed onto the rear face of the profile bottom and be fixed for example by crimping or bolting.
  • the drive module can be direct manual control and include an actuating crank and an output gear wheel integral with the rack pinion.
  • Another possible module is constituted by a motor-reducer, the assembly plate of which can be fixed by bolting, both on the bottom of the C-profile and on the median surface, of generally planar shape, of a mount in which the one or two fixed slides are formed perpendicular to the axis of symmetry.
  • an advantageous solution proposed by the invention consists in providing between the actuating crank and the pinion of rack and pinion a transmission by toothed belt, comprising a toothed driving pulley, integral with the crank, and a receiving toothed pulley secured to the rack pinion and in which is preferably incorporated an irreversibility brake.
  • This arrangement allows, thanks to the position of the pinion centered on the axis of symmetry, to mount the transmission on one side or the other of this axis and to place the crank, by means of the choice of an appropriate length of belt. , at any distance from the axis of symmetry.
  • the slide is advantageously a molded plastic part, which, over at least part of its length, has a U-shaped profile ensuring guidance in the slide, the rack being formed in the internal face of one of the branches of the profile .
  • the window regulator according to the invention is intended to equip a door 1 of a motor vehicle (fig.
  • each slide has a U-shaped profile, the opening of which faces the internal panel 4 and the sides of which guide a domed roller 23 rotatably mounted at one of the ends 24 of a corresponding arm 26 or 27.
  • the two arms 26, 27, of equal length, are connected to each other, a short distance from their other end 28, by a hinge 29 carried by a slide 30 guided in a rectilinear slide 31, in principle vertical.
  • the crossed arms 26, 27 carry a roller 51 which has the same convex shape as the rollers 23 disposed at the end 24, of the arms and which is engaged in rolling contact with the sides of one of two slides central units 54 perpendicular to the axis YY of the slide 31, whose U-shaped profile is open towards the external panel 3, and which are part of a frame 50 whose central part 55, of generally planar shape, is fixed by bolting at 56 on the internal panel 4.
  • Rigid ribs 55a are however formed in the flat surface 55.
  • the axis XX common to the slides 54 constitutes a horizontal central line that the arms 26, 27 can cross, despite their crossed mounting , during their angular deflections under the effect of the movement of the slide 30, thanks to the fact that one of the arms, 26, consists of two half-arms 26a, 26b, located on either side of the other arm, 27, which is in one piece, and made integral with each other in worm tu of the special arrangement of the articulation 29 connecting the arms at their crossing point (fig. 3).
  • This articulation 29 comprises a pin 57 which is integral with the slide 30 and is engaged in sliding contact inside a sleeve 58 passing through holes 59, 61, 62 made respectively in the half-arm 26a, the arm 27 and the half-arm 26b, and the peripheral surface of which comprises a cylindrical part 63 engaged in contact with the hole 61, of circular shape, of the arm 27 for premitting a relative rotation, and on either side of this cylindrical part, parts prismatic 64 in engagement with the square outline of the holes 59, 62 to ensure by keying a blocking in relative rotation of the half-arms 26a, 26b.
  • the arms 26, 27, which are symmetrical with respect to the axis YY of the slide 31 and therefore make with the central line XX equal angles and in opposite directions, constitute thin blades which make them flexible, which allows them to adapting to the curve of the glass 9. These arms can also undergo translational movements along the pin 57, integrally with the sleeve 58.
  • the slide 31 forms a C-shaped section open towards the external panel 3, the bottom 34 of which is fixed, for example by welding, to the flat central part 55 of the frame 50.
  • the slide 30, which preferably constitutes a molded plastic part, has from its upper end and over most of its length, a U-shaped profile, the two branches of which are guided in sliding contact with the bottom 34, the sides 35 and the edges 36 of the C-shaped section 31.
  • a toothing 38 constitutes a rack for engaging a drive pinion.
  • the toothing 38 is preferably molded with the slide but it can also be formed by an insert, for example made of metal.
  • a housing 39 is provided in the slide 31.
  • This housing which is located in part in line with a notch 55b of the frame 50, is constituted by a cavity delimited by a part cut at 40 in the bottom 34 of the profile 31 and deformed towards the inside of the latter by so as to define a central flat wall 41 between two lateral openings.
  • the wall 41 is parallel to the bottom 34 but is offset enough to be on the opposite side of the rack 38, that is to say in the vicinity of the bottom of the internal cavity of the slide, as shown in Figure 2.
  • It is in addition pierced with a square hole 47 in which is embedded a bearing 48 made of plastic material with a low coefficient of friction, for the reception of the pin-forming end of the rack pinion.
  • projections 31a forming a stop are formed at the lower end of the section 31.
  • the window regulator according to the invention can be considered to be of modular construction, in the sense that the basic structure, which has been described with reference to FIGS. 1 to 3, can be combined with different mechanical assemblies, or modules, for meet specific conditions of use.
  • a module essentially comprising a rack pinion 70 and a receiving toothed pulley 71, secured to this pinion and connected by a toothed belt 72 to a toothed driving pulley 73 mounted on the internal panel 4 and the shaft 74 of which receives an actuating crank 76.
  • a cup 78 comprising a peripheral flange 79 fixed, for example by welding, on one of the faces of a support plate 81 which, at its two ends, is provided of a hole 82 through which the rim 32a of the respective holes 32 of the profile bottom 34 is crimped, thus ensuring the connection of the profile with the plate 81.
  • the latter also comprises an opening in which is embedded a bearing 83 made of material plastic with a low coefficient of friction, which receives a cylindrical bearing 84 of the pinion 70, the end journal 86 of which is itself engaged in the bearing 48 of the wall 41.
  • the hub 87 of the toothed pulley is fixed by fitting, or by splines , on an extension 88, of smaller diameter, of the bearing surface 84, the axial retention towards the internal panel 4 being ensured by a mating of the end 89 of the pinion opposite the pin 86.
  • an irreversibility brake 91 is disposed inside the bowl 78.
  • This brake is of conventional construction and essentially comprises a spring 92 inserted by force and under tension in the bowl 78 to ensure the immobilization of the pulley, which can however rotate freely when a torque is applied to it, by the effect of a loosening of the spring due to the action of a fork 93, inside the spring, which is secured to the hub 87 and is engaging the ends of the spring 92.
  • the driving pulley 73 is fixed to the panel 4 by means of a stirrup 94 with uneven branches, between which the shaft 74 journals (fig. 6).
  • the mounting point of the stirrup 94 can be chosen at will both in height and in distance relative to the axis YY of the slide 31, this distance being determined by the length of the toothed belt 72.
  • the mounting is provided on the left of the YY axis in FIG. 4, but it could obviously be produced on the right, as indicated in broken lines in 72 ′.
  • the irreversibility brake 91 could, of course, be incorporated into the driving pulley 73 instead of being incorporated into the receiving pulley 71.
  • the module adopted in Figures 7 and 8 is a direct control mechanism comprising in a housing 96 a pinion 97, whose shaft 98 receives an actuating crank 76, and which is engaged with a toothed wheel 99 with which makes body the rack pinion 70, the pin 86 of which is engaged, as in FIG. 5, in the bearing 48.
  • the housing 96 has two end wings 101 which are crimped at 32a on the bottom of the slide 34, in the same way as the support plate 81 of FIG. 5.
  • An irreversibility brake 91 is mounted in the housing 96, between a shoulder 98a of the shaft 98 and the pinion 97.
  • the housing 96 could be mounted in a position offset by 180 ° with respect to the position shown, provided that corresponding anchor points are provided in the profile bottom 34.
  • the module incorporated into the basic structure is constituted by a gear motor 105 whose output element is the rack pinion 70.
  • This pinion is engaged in the housing 39, as in the previous examples, and the assembly plate 106 of the motor-reducer 105 is fixed by bolting, or by equivalent means, on the one hand to the points 33 of the flat central part 55 of the frame 50, on the other hand through the lower bore 32 of the profile bottom 34.
  • the assembly plate 106 as is the case of the support plate 81 (fig. 5) and of the housing 96 (fig. 8), is applied against the flat bottom 34 of the profile 31 .
  • the support plate 81 is replaced by a casing 108, generally of omega shape, the wings 109 of which are also crimped at 32a on the profile bottom 34 , and in an opening 111 from which the end 90, opposite the pin 86, of the pinion 70 revolves. Furthermore, the end face of the pulley 71 has sliding contact with the adjacent wall of the casing 108.
  • the stroke of the slide 30 forming a rack is approximately 140 mm, which is small compared with that, which should be of the order of 400 mm, of the rack described in the application FR 2 310461 cited above.
  • the invention is not limited to the window lifter with crossed arms shown in the figures res 1 to 6, but also extends to a single-arm window lift pivotally mounted on an axis carried by a slide such as that shown in FIG. 8.
  • the lower edge 14 of the glass is embedded and retained in a central horizontal slide 117, with a U-shaped profile, the sides of which guide the roller 23 rotatably mounted at the end of the arm 126.
  • the roller 51 carried by the opposite end of the arm 126, moves, like those arms 26, 27, in a slide 54 of a half-frame 50 fixed, on the one hand on the internal panel 4, and on the other hand on the profile 31.
  • the arm 126 pivots directly on the pin 57 of the slide 30, under the action of a pinion control mechanism 70 mounted in the housing 39 of the bottom 34 of the profile. It thus moves in the same way as the arm 26 or 27, on either side of the line formed by the fixed slide 54.
