Definitions

  • the present invention relates to a window regulator, in particular for a motor vehicle, of the type comprising a slide, a carriage integral with the window and capable of being moved along the slide by means of a cable passing over two deflection pulleys and winding on a drum of an operating winch.
  • window regulators are commonly used to raise and lower the windows of the doors of motor vehicles.
  • doors of vehicles currently manufactured are convex, it follows a curvature of the slides along which move the carriages integral with the windows.
  • the length of the cable between the two deflection pulleys is equal to the sum of the cable lengths of each of the pulleys to the carriage, that is to say the sum of the two short sides of the variable triangle whose tops are formed by the two pulleys and the carriage.
  • the length of the cable between the two return pulleys therefore varies when the carriage moves from one end to the other of the slide, which causes a variation in the tension of the cable.
  • the device described in FR-A-2 193 412 attempts to remedy this drawback by using at least one elastic pulley and sheath stops making it possible to ensure, by prestressing the sheaths enveloping the cable, a suitable tension of the cable maneuver.
  • this solution causes inconvenience for the user (play before operation at the level of the operating crank and / or greater effort to be exerted on it approximately halfway) and causes premature wear of the lifter. glass due to the tensions exerted on its various elements.
  • a window lifter device comprising a drum for winding the actuating cable, which has a frustoconical shape to allow the traction to be increased during a window lifter operation. This has a number of drawbacks, particularly in terms of comfort of use.
  • the present invention proposes to remedy these drawbacks.
  • the object of the invention is therefore to provide a cable window regulator in which the cable tension remains constant, which is pleasant to handle for the user and whose lifespan is extended compared to cable window regulators produced up to now.
  • the subject of the invention is a window lifter, in particular for a motor vehicle, of the type comprising a curved slide, a carriage secured to a window and capable of being moved along the slide by means of a cable. passing over two idler pulleys and winding on a drum of an operating winch.
  • the winch drum has a variable cross section so that the length of the coiled cable varies depending on the position of the carriage on the slide.
  • the cable consists of two strands each attached to one end of the drum, and said cross section increases from one end of the drum to a maximum corresponding to the most distant point of the slide. an axis passing through the two pulleys then decreases to the other end of the drum.
  • the cable consists of a single strand and the cross section decreases from one end of the drum to a minimum corresponding to the point of the slide furthest from an axis passing through the two pulleys then grows to the other end of the drum.
  • the shape of the drum is of revolution. It can for example be biconical.
  • the window regulator shown in fig. 1 comprises a curved slide 1, at the ends of which two pulleys 2 and 3 are fixed.
  • the slide 1 is, in a manner known to those skilled in the art, constituted by a tube 4, comprising a longitudinal slot 5 in which a carriage slides 6 secured to a support 7 in which a window 8 is enclosed.
  • an upper strand S and a lower strand I which pass respectively over the idler pulleys 2 and 3 and are wound on a drum 9 of an operating winch 10 comprising a crank 11
  • the cable strands S and 1 are contained in sheaths 12 and 13 connecting the pulleys 2 and 3 to the operating winch 10.
  • These strands S and are each fixed to one of the ends of the drum 9, respectively at points A and B, as shown in fig. 3.
  • the strands S and 1 are wound in the opposite direction in a helical groove 14 formed on the surface of the drum 9 which can, for example, be biconical in shape.
  • a helical groove 14 formed on the surface of the drum 9 which can, for example, be biconical in shape.
  • the pitch of the helical groove has been enlarged in fig. 3.
  • the turns of the groove 14 should be located side by side.
  • the drum 9 If the drum 9 is rotated in the direction indicated by the arrow T, in order to lower the window 8, the strand S unrolls, leaving free at each turn, a turn 15 of the helical groove 14 on which comes s' in roll the strand 1.
  • the free turn 15 moves, as the drum 9 turns, from B to A.
  • the length of the free coil 15 increases from point 8 to a maximum located at mid-stroke and corresponding to the point of the slide furthest from a CC axis (fig. 2) passing through the two pulleys, before decreasing to point A.
  • This variation in the length of the free coil 15 makes it possible to compensate for the variation in the length of cable between the two return pulleys 2 and 3, this is ie the variation of the sum of the two short sides S 'and l' (fig. 2) of a variable triangle whose vertices are constituted by the two pulleys 2 and 3 and the carriage 6.
  • This triangle is represented in fig . 2 which shows the carriage 6 in two different positions: halfway in solid lines and end of stroke in dotted lines.
  • the window regulator cable fitted with a drum as shown in fig. 3 has a tension which always remains constant when the carriage is moved from one end to the other of the slide.
  • the effort to be exerted on the crank is therefore regular, which has an advantage for the user.
  • the service life of such a window regulator is extended compared to window regulators in which the cable tension varies.
  • the shape of the drum 9 is of course a function of the curvature of the slide.
  • the drum 9 is therefore not necessarily symmetrical with respect to a plane perpendicular to its axis, like the drum shown in FIG. 3, it is only so if the assembly, formed by the slide and the pulleys, is itself symmetrical.
  • the shape of the drum is of revolution in order to simplify its production.
  • FIGS. 4 and 5 show two possible variants of the shape of the drum, referenced respectively by 16 and 17.
  • the drum 16 (fig. 4) is in the form of two flared parts 16a and 16b connected together by their faces of larger diameter and the drum 17 (fig. 5), in the form of a barrel.
  • the cable could consist of a single strand, the two ends of which would be fixed on either side of the carriage.
  • the shape of the drum would then be designed in the same way as previously so as to wind the cable on a slightly smaller or slightly larger turn than the turn from which the cable is unwound; for example, the drum could be in the form of a diabolo 18 shown in FIG. 6 and on which a portion of a cable 19 is wound, the portion of wound cable moving for example from the end 20 to the end 21 of the drum 18 when the latter is rotated in the direction of the arrow T ' .
  • the cross section of the drum then decreases from one end of the latter to a minimum corresponding to the point of the slide furthest from the axis CC passing through the two pulleys then increases to the other end of the drum .
