Definitions
- the present invention relates to an electric vehicle window regulator according to the preamble of claim 1.
- window regulators with rack cable window regulators with twisted cable (Bowden cable), and window regulators with arms and toothed sector.
- the invention relates to the first two types of window regulator.
- the system When an obstacle is on the closing path of the window, the system must recognize the presence of an abnormal phenomenon and, if the force on the window exceeds a limit value, the window must not continue its trajectory, but s '' stop and at least release the effort.
- This release of the force can be obtained either by releasing the glass which descends under a weak force or under the effect of its own weight if the friction in the lateral joint allows it, or by reversing the movement of the glass which is then forced to descend.
- GB-A 1 184 645 describes a window regulator without cable guide rail, in which the motor is pivotally mounted on an axis integral with the door frame and the reaction of the motor on the door is measured.
- This window regulator has pulleys which must be linked very rigidly in the absence of a sheath for the cable, which imposes significant rigidity on the assembly in order to obtain a faithful and precise measurement.
- this known window regulator only provides for the automatic stopping of the motor at the end of the stroke, and not an automatic reversal of the direction of rotation of the motor in the event of an obstacle in front of the window.
- the invention aims to provide a window regulator of the aforementioned type, which is simple to manufacture and therefore inexpensive.
- the window regulator has the characteristics mentioned in the characterizing part of claim 1.
- the electric switch is part of a motor supply and control circuit, capable of reversing its direction of rotation in a manner known per se.
- Such a safety device is relatively simple in structure and therefore inexpensive.
- Figure 1 is a partial schematic elevational view of an electric window regulator with twisted cable or Bowden cable, equipped with a safety device.
- Figure 2 is a partial sectional mid-elevation view, on an enlarged scale, showing the safety device of Fig.1.
- Figure 3 is a view similar to Fig.1 illustrating an embodiment of a security device according to the invention.
- the window regulator 1 shown in Fig.1 comprises a geared motor 2 for driving a twisted cable or Bowden cable 3, passing around two pulleys 4, 5 for returning.
- the strand of cable 3 located between these two pulleys extends along a guide rail 6, and carries a carriage 7 which supports the glass (not shown).
- the upper pulley 4 is mounted on a fixed plate 8 on which is fixed a sheath 9 extending over an appropriate length around the cable 3.
- a sheath 9 extending over an appropriate length around the cable 3.
- a helical spring 11 coaxial with the cable 3, of which one end is supported on the fixed plate 9 and the opposite end is supported on an element 12 capable of being displaced by the cable 3 by friction against the latter, against the return force of the spring 11.
- this element 12 is a tubular part which can slide inside the sheath 9, coaxial with the cable 3 and provided with a lateral tab 13 cooperating with the contact of an electric switch 14 mounted on a fixed support 15, such as the door panel (not shown).
- the spring 11 acting by compression with a determined prestress the operation of this security is as follows: as long as the force which the cable 3 has to transmit to the carriage 7 and to the window pane to raise the latter does not exceed a predetermined value , corresponding to the prestressing force of the spring 11, the latter maintains the tubular part 12 in a position such that its lug 13 actuates the weighing switch 14. If on the other hand, following the interposition of an obstacle on the closing path of the window, the force F that the cable 3 must transmit exceeds the limit set by the preload of the spring 11, the tubular part 12 slides in the sheath 9 against the restoring force of the spring 11 which is thus compressed.
- this movement separates the part 12 and the tab 13 of the switch 14 which is no longer actuated.
- This change of state of the switch triggers a command to invert the direction of rotation of the motor of the gearmotor 2 by the electrical supply circuit of the latter, of which the weighing switch 14 is a part.
- This type of safety device requires an electrical circuit with an electrical memory, since it returns almost immediately to its starting position after detection and reversal of the direction of movement.
- the invention is also applied to a window regulator 1 of the twisted cable type 3, but this is modified as follows.
- the upper pulley 7 is mounted at the end of a lever 16 articulated around an axis 19 on a fixed member, namely in the example shown the door panel 17.
- the electromechanical safety means according to the invention also include elastic means for holding the lever 6 and the pulley 4 in a determined angular position.
- These means consist, in the example described, of a compression spring 18, one end of which is fixed to the lever 16 and the other end of which is fixed to the panel 17.
- the spring 18 acts on the part of the lever 16 situated on the side of the axis 19 opposite the pulley 4.
- the electromechanical safety device finally comprises an electrical switch 21 fixed for example on the support 17, and positioned so as to be able to cooperate with the end of the lever 16 opposite to the pulley 4.
- the switch 21 is part of a control circuit known per se, not shown, with electric memory like that associated with the safety of FIGS. 1 and 2. It cooperates with the lever 16 so as to be in a first state, when it is actuated, as long as the lever 16 and the pulley 4 remain in an angular position determined by the compression force of the spring 18, which exerts on the lever 16 an effort tending to maintain the pulley 4 in position high and cable 3 stretched.
- the switch 21 goes into a second state when it is no longer actuated owing to the fact that the lever 16 as well as the pulley 4 tilt under the effect of a force, exerted on the glass, exceeding the limit value resulting from the compression of the spring 18 and of its lever arm with respect to the tilting axis 19. In fact the end of the lever 16 then departs from the switch 21, the pulley 4 lowers at 4a and the lever 16 switches to position 16a.
- the electrical circuit of which the switch 21 is a part automatically controls the reversal of the direction of rotation of the motor of the geared motor 2.
- the invention is not limited to the embodiments described and may include various variant embodiments. It relates to all means capable of weighing the force cable on the glass. Indeed, this effort is transmitted to the cable 3 via the carriage 7, so that the effort on the cable gives a good image of the effort on the glass.
