Definitions

  • the safety device mcludes a device responsive to operation of the time- [56] References C'ted lagged relay for preventing the double-pole reverser UNITE STATES PATENTS from causing raising of the window during the time-lag fth l 2,737,621 3/1956 Hamilton ..3l8/266 6 re ay 3,513,374 5/1970 Koment ..3l8/266 Claims, 4 Drawing Figures SAFETY DEVICE FOR ELECTRICAL WINDOW REGULATOR This invention relates to a safety device for electrical window regulators.
  • the object of the present invention is first to avoid this risk, by neutralizing the effect of such an unfortunate reaction, by the addition to the combination of means disclosed in the above mentioned application and including a conventionnel. reverser and a timelagged reversing relay, of auxiliary circuits, one shunting the terminals of the reverser actuated by the raising or lowering buttons, whilst it is capable of being closed or opened, and another one inserted into the exciting circuit of the time-lagged reversing relay, by means of respective switches, the working of which is coupled with that of the said time-lagged reversing relay and in such a way that it is its excitation which brings about the opening of the said circuits and during the whole of the duration of the time-lag.
  • H T
  • a further object of the invention is to allow, the use of a single pair of reversers to allow one to realize successively the working of four window-regulators and even, if necessary, the operation of the hood or of the trunk of the vehicle for example, through the effect of the combination of the said pair of reversers with a socalled selector device, allowing a sort of switching, successively, of each of the mechanisms of windowregulators or other electric mechanisms.
  • FIG. I shows the diagram of the two double-pole reversers and of the wiring ensuring the feed of an electric motor having reversal of rotation and of the corresponding safety device of an electric window-regulator of a car door, as well as the addition to this diagram of a selector allowing successively the raising operation of the window associated with each of the four windowregulators;
  • FIG. 2 shows the same diagram but in the position of I about the excitation of the time-lagged reversing relay through the safety device and, automatically, the lowering movement of the corresponding windowregulator; and l 4 FIG. 4 again shows the'same diagram, but now assuming that the conventional reverser is operated during the duration of the time-lag of the reversing relay excited in accordance with FIG. 3, to show that in this situation the action of the lowering button of the window on such conventional reverser is neutralized and so does not bring about about the upward movement of the window.
  • FIGS. 1 designates a conventional doublepole reverser, the rocking of which ensures alternately, through the two customary raising or lowering buttons of a vehicle, the corresponding operations of each window-regulator, whilst 2 designates a time-lagged (preferably pneumatically) auxiliary reversing relay, which delays by several seconds its return to a position of rest, when its winding 3 has been excited by the mutual contact of the conductors, normally separated, 4 and 5 of a safety device for detecting any squeezing pressure between the door frame and the window.
  • a time-lagged (preferably pneumatically) auxiliary reversing relay which delays by several seconds its return to a position of rest, when its winding 3 has been excited by the mutual contact of the conductors, normally separated, 4 and 5 of a safety device for detecting any squeezing pressure between the door frame and the window.
  • this timelagged reversing relay 2 is improved by the fact that the rocking of its stirrup ensuring the double-pole reversal also entails the working of two auxiliary switches 6 and 7, respectively inserted on the one hand into the auxiliary circuit for neutralizing the effect of the lowering button of the reverser 1 and on the other hand into the exciting circuit for the winding 3, so as to open these auxiliary circuits, during the whole of the duration of the time-lag.
  • 8 designates a selector, for example of the so-called keyboard type, allowing one to transfer the combined effects of the reversers l and 2 and of their aforesaid auxiliary circuits successively to each of the motors M having reversal of run and their corresponding safety devices.
  • a safety device for an electrical window regulator operated by a dc motor comprising a wiring circuit for energizing said window regulator from a dc. source and including a double-pole reverser operated by buttons permitting to reverse the polarity of the potential applied to the motor so as to cause raising or owering of a window of a vehicle, a squeezing pressure detector located adjacent the top of the window and responsive to the insertion of an obstacle between the top of the window and the top of the door of the vehicle during raising of the window, a time-lagged reversing relay responsive to said pressure detector when an obstacle is detected for reversing the polarity of the potential applied to said motor for lowering said window during a time interval sufficient to permit removal of said obstacle, and means responsive to said time-lagged relay for preventing inadvertent raising of the window during said time interval'by operation of the lowering button of the double-pole reverser.
