Definitions

  • the present invention relates to safety devices for electric windows of motor-vehicles of the type comprising a window pane which is slidably mounted within guide means between an opened and a closed position, a support element rigidly connected to the window pane, and window control means for moving said support element along a direction substantially parallel to the sliding direction of the window pane in order to cause displacement of the window pane between the opened position and the closed position.
  • Safety devices for electric windows of motor-vehicles comprise sensor means including an elongated hollow element of elastically deformable material arranged along the upper edge of the window aperture and containing inside two metal foils which come into contact with each other closing an electric circuit as soon as the intruded body is pushed by the edge of the pane against the elongated hollow element, so as to activate the window control device in order to stop and/or invert the actuating electric motor.
  • sensor means including an elongated hollow element of elastically deformable material arranged along the upper edge of the window aperture and containing inside two metal foils which come into contact with each other closing an electric circuit as soon as the intruded body is pushed by the edge of the pane against the elongated hollow element, so as to activate the window control device in order to stop and/or invert the actuating electric motor.
  • the object of the present invention is that of providing a safety device for electric windows of motor-vehicles which is of extremely simple and economic manufacture, which may be adapted easily also to windows initially not provided with a safety device, and which at the same time is characterized by a high precision and reliability and ensures therefore a high degree of safety.
  • the invention provides a safety device for an electric window of a motor-vehicle of the type indicated at the beginning of the present description, characterized in that: said control means acts directly on an auxiliary element separate from said support element, said auxiliary element is slidably mounted on the support element in a direction substantially parallel to the sliding direction of the window pane, spring means are interposed between the auxiliary element and the support element, so that an upward movement of the auxiliary element caused by said control means is transmitted by said spring means to the support element and the window pane connected thereto, which move along with the auxiliary element, whereas when a closing movement of the window pane is opposed by the intrusion of a foreign body in the window aperture, the auxiliary element is moved with respect to the support element against said spring means, sensor means are provided for sensing a relative movement of the auxiliary element with respect to the support element, to enable the movement of the window pane to be stopped and/or inverted in case the closing of the window pane is opposed.
  • said sensor means are comprised of a proximity electric switch and a striker element cooperating therewith which are supported by the support element and the auxiliary element and come into engagement which each other as a consequence of a relative movement of said elements.
  • said spring means are comprised of at least a helical spring mounted on a guide pin carried by said support element and slidably engaged within a corresponding hole of said auxiliary element.
  • the device according to the invention is much simpler and more economic with respect to the known devices, it may be adapted easily to a window which is initially not provided with a safety device, and also is characterized by a great precision of operation and by a resulting high degree of safety.
  • reference numeral 1 generally designates a motor-vehicle door whose structure comprises a lower panel 2 and a window frame 3 defining a window aperture 4.
  • Reference numeral 5 designates the window pane, which is slidably mounted within guides 6, 7, 8, provided in the door structure, between a lowered opened position (shown in figure 1) and a raised closed position.
  • a support element 9 which is slidably guided within guide 7 and is moved along this guide by an electric motor 10 whose output shaft, in the case of the illustrated embodiment, is connected through a flexible connecting member 11 to a screw which engages a nut connected to the support element 9.
  • electric motor 10 and driving shaft 11 may be provided in any known way and do not fall, taken per se , within the scope of the invention. For this reason, and also in order to render the drawings more simple and easy to understand, said construction details have not been illustrated herein.
  • Screw 12 engages a nut 13 which is carried by an auxiliary element 14 which is separate from the support element 9 and is slidably mounted on guide pins 15 of the support element 9 along a direction substantially parallel to the sliding direction of pane 5.
  • the sliding movement of the auxiliary element 14 with respect to the support element 9 is also guided by the engagement of a pin 16 of the auxiliary element 14 in a slot 17 of the support element 9.
  • Helical springs 18 are mounted on guide pins 15.
  • the support element 9 and the auxiliary element 14 are also provided respectively with a proximity micro-switch 19 and a striker member 20 constituted by a screw adjustable in position which come into contact with each other as a result of a movement of support element 9 and auxiliary element 14 towards each other.
  • door 1 is also provided with a limit switch 21 able to detect the reaching of the raised position by pane 5 and to deactivate accordingly the safety device, in order to allow the normal closing of the window pane.
  • the limit switch can be provided on the auxiliary element 14, so that it is not necessary to deactivate the safety device in the final portion of the closing stage.
  • electric motor 10 is activated to move pane 5 between its opened and closed position.
  • the rotation of the output shaft of the electric motor 10 is transmitted by the driving shaft 11 to screw 12 which causes a resulting displacement of nut member 13 thereon, since the latter is prevented from rotating.
  • Auxiliary element 14 moves along with nut member 13. In case of a downward movement, the auxiliary element 14 transfers its movement to the support element 9, and also to pane 5, through pin 16 which engages the lower end of slot 17 of the support element 9.
  • helical springs 18 which have a load sufficient to be exploited to this end.
  • auxiliary element 14 If a foreign body intrudes in the window aperture during its closing, opposing the raising of pain 5, the support element 9 consequently stops or slows down, whereas the auxiliary element 14 continues its movement under the action of screw 12.
  • the auxiliary element 14 therefore moves upwardly (with reference to figure 2) with respect to support element 9, biasing spring 18 and bringing screw 20 in contact with micro-switch 19, whose activation is used, in a way known per se (not illustrated herein) to stop or invert rotation of electric motor 10.
  • auxiliary element 14 has been illustrated as sliding in a vertical direction with respect to the support element 9, whereas the latter is moved along with pane 5 along a direction which is slightly inclined with respect to the vertical direction.
  • this different inclination does not causes inconveniences, since the guide pins 14 engage the corresponding holes of auxiliary element 14 with play and since the stroke of the auxiliary element 14 with respect to the support element 9 necessary to activate micro-switch 19 is very reduced and at maximum of some millimetres.
  • guide pins 15 and slot 17 may be provided along the same direction of guide 7 which is slightly inclined with respect to the vertical direction.
  • the safety device according to the invention is extremely simple and economic to manufacture and at the same time is very effective and reliable. It also may be adapted with simple operations to an electric window which is initially not provided with a safety device of this kind.
  • the closed position of the pane 5 is defined by a stop member (not shown) carried by the door structure, which cooperates with support element 9 to stop the pane in its closed position without causing any compression of springs 18.
  • the use of microswitch 21 is thereby avoided.
  • microswitch 19 is carried by the fixed structure of the door, so as to avoid any electric cable connected to moving parts, whereas screw 20 cooperates with a movable button which transmits its movement to the microswitch through a mechanical transducer, such as a flexible cable.
