Definitions

  • the present invention relates to an anti-forcing device for manually-operated window winders of motor vehicles, practically consisting of a set of rolling members acting against the inner circumferential surface of the box-shaped body which contains the mechanisms which enable the same glass to be let up and down from the interior, by means of the purposely provided handle.
  • the present invention partially reduces said force, while simultaneously improving the anti-forcing security, whose chatacteristics are required in many countries by the technical specifications relevant to the window winders for motor vehicles. It comprises a set of rolling members, such as, e.g., balls placed in a radial position, pushed by contrast springs, so as to act as an antifriction force along the inner circumferential surface of the box which contains all of the mechanisms of the window winder.
  • the present device is the technically most advanced solution against the forced letting down of the glasses of motor vehicles, and it should be stressed that, inasmuch as the axial spring is got rid of, the actuation of the window winder from the interior of the vehicle, with the necessary force being now of approximately 0.4 N only, also results must easier.
  • the device 1 omprises a box-structured container body 2 of cylindrical shape, inside which the drive spindle 3 is contained, which spindle is integral with the gear wheel 4 which, as known, acts on the rack cable which causes the glass to go up and down.
  • a plate 6 with four radial sectors 7, 8 is mounted, wherein two from said sectors, indicated by the reference numeral 7, comprise an inwards-bent lip 9 which, when the handle is rotated, acts on the circumferential balls 10, slightly loading the contrast springs 11 in order to reduce the force of adhesion to the inner circumferential wall 12 of the box-­structured body 2 as extensively as possible.
  • rollers or runners could be indifferently used as well - which, obviously, do not modify the dynamics of operation of the present invention, but, on the contrary, make more genral its use, in order to adapt it to any types of vehicles, also as a function of the manufacturing costs.
