Definitions

  • the invention relates to automotive cable windows, and in particular window regulator sliders.
  • Document FR-A-2 728 008 describes a window regulator having two rails parallel guiding two cursors in translation in the direction of movement of the window. At each end of the rail, a respective cable return is fixed. A cursor is attached to the front of the glass. This cursor is made up of two sliding parts one with respect to the other in the direction of movement of the glass. The sliding between the two parts of the cursor allows the glass to pivot around an axis normal to the glass. Each cursor is guided by surface contact with a corresponding rail. The guiding of the window with respect to the rails and with respect to to a window frame is thus hyperstatic. The friction to overcome to move the glass are so important. At the end of the race, each cursor vertically exceeds the level of a referral.
  • the orientation of the cable between the most close and the cursor forms a significant angle relative to the direction of moving the glass.
  • the training effort of the cursor is thus increased.
  • the support for a cable return pulley can thus be deformed.
  • the wear of the cable and the power of the motor drive motor are thus increased.
  • the glass placement relative to the top seals of a glass frame is also uncertain.
  • the subject of the invention is therefore a window regulator, comprising a guide rail, a slider having a part for receiving a window and sliding relative to the rail following a guide path of the rail, pivoting about an axis perpendicular to the stroke and placed in a plane parallel to the mean plane of a window attached to the party reception.
  • the cursor has an angular pivoting stroke in the rail included greater than 2.8 degrees.
  • the cursor has an area of contact with the rail. less than 16 mm in length in one direction of travel.
  • the window regulator also has a cable return arranged in the path of the cursor, a cable passing through the cable return, a part cable fixing in the slider, a recess in the slider shaped to allow the sliding of the reference.
  • the window receiving portion extends in the direction of the race beyond the reference when the cursor is at the end of the race.
  • the cable extends substantially in the direction of the cursor travel between the gear and the fixing part.
  • the rail has a groove and the cursor has a stud inserted in the groove.
  • the window regulator has a play along its axis longitudinal between the stud and the bottom of the groove, greater than 3.5 mm.
  • the invention also relates to a door comprising a window regulator such as described, further comprising a window fixed on the window receiving part, a glass frame blocking the pivoting of the glass around the pivot axis of the cursor.
  • the guide rail is formed by a window frame.
  • FIG. 1 to 3 show parts of a window regulator 1 according to the invention.
  • This window regulator typically comprises two guide rails 2. These guide rails 2 can be mounted on either side longitudinally of a door. These rails extend substantially vertically in a direction of glass movement desired.
  • Each rail 2 has a groove 3, serving as a cursor guide.
  • a cursor 5 pad 4 is for example inserted in the groove 3 of a rail 2.
  • the rail 2 and the slider 4 are thus shaped to allow relative sliding according to the rail guide travel.
  • Rail 2 and slider 4 are also shaped to allow pivoting about an axis perpendicular to the stroke and in a plane means parallel to the mean plane of a window added and fixed to a part of reception, and passing through the middle of the cursor.
  • This axis will be called the X axis in the rest of description.
  • This X axis is substantially parallel to the longitudinal axis of the vehicle when the door is closed.
  • This pivoting between rail 2 and slider 3 reduces the hyperstatism of the glass guide compared to a door. Indeed, according to the invention, the guide of the window in a door frame hardly any deformation effort at the level of the guide between the slider and rail. The friction between the slider 4 and the rail 2 is thus reduced.
  • the cursor has a pivoting stroke angular greater than 2.8 degrees.
  • An angular travel of 4.3 degrees is particularly suitable for reducing friction. around the X axis when the glass is assembled to the cursor.
  • the pivoting around of the X axis is ensured by a stud of a length, according to the direction of the race, less than or equal to 16 mm. It can also be provided that the clearance between the faces of the pad 5 and the faces of the slot 3 is greater than 0.5 mm.
  • We can also plan that the contact between the cursor and the rail is close to a linear contact according to a direction along the X axis. In general, the more the contact surface is reduced between the rail and the cursor, the closer we get to the point or line contact.
  • the window regulator further includes a cable return disposed in the travel of the slider.
  • the reference 7 is a pulley disposed in the groove of the guide rail in the example.
  • a cable 8 passes through a groove in the reference 7.
  • the cable 8 is fixed in a fixing part 9 of the cursor 4.
  • This part of fixing 9 has for example a first bore 11 facing the pulley, allowing the passage of the cable 8.
  • This fixing part 9 also has a second bore 12 leading to the first bore and located on an opposite face at this first bore.
  • This bore has a section greater than the first bore.
  • a shoulder is thus provided at the intersection of the two bores 11 and 12.
  • a ferrule stop 13 of section greater than the section of the first bore, on the end of the cable.
  • the stopper tip 13 comes into contact with the shoulder to ensure cable retention 8 on the slider 4.
  • a cursor having a recess 15 is used to allow the sliding of the reference 8 relative to the cursor in the direction of travel of the cursor.
  • the cursor travel can thus be increased, or the size of the window regulator 1 can be reduced for a given slider stroke.
  • the cursor 4 has another recess 16, opposite the recess 15, to allow the sliding of another reference relative to the cursor following the direction of the cursor travel.
  • the cable 8 extends substantially in the direction of the cursor travel between the gear and the fixing part. This characteristic is obtained by placing, for example, the fixing part 15 opposite between two cable returns. The guiding of the cable (s) in the returns is thus improved. On the other hand, the force to be applied on the cable to move the cursor varies bit along the cursor stroke.
  • the window receiving part extends beyond a return following the direction of the race, when the cursor is at the end of the race. This allows in particular to bring the glass receiving part 6 closer to the line of vehicle belt. This also makes it possible to obtain a size of window regulator reduced for one stroke and one part for receiving glass.
  • the invention also relates to a door.
  • Figure 4 shows a embodiment of a door according to the invention.
  • the door 17 includes a window regulator as described above, a window 10 fixed on the receiving part of window and a window frame.
  • the glass frame 18 blocks the pivoting of the glass 10 around the X axis. It is thus possible to provide for the window to slide in a groove formed in the window frame.
  • the glass is shown in solid lines in position closed and in broken lines in the open position. The groove thus ensures the blocking of the pivoting and guiding the glass.
  • the cursor guide rail 2 is formed in a extension of the window frame 18. It is thus possible to provide for guiding the cursor in the groove used to slide the window. In this case, we can consider using the window regulator and the window frame as structural elements or as reinforcements of the door.
  • the present invention is not limited to the examples and methods of realization described and represented, but it is susceptible of numerous variants accessible to those skilled in the art. So although we mentioned a window lifter with two rails and two sliders, we can also consider a window regulator for example with a single slider sliding in a single rail. Furthermore, although we has described the guidance between the rail and the slider with a stud inserted in a groove, we may also use any other guidance ensuring the essential functions of the invention.
