Definitions

  • the present invention relates to a device for opening the tailgate of motor vehicles, in particular motor cars.
  • tailgates of motor vehicles in particular motor cars, have systems for locking/unlocking the tailgate with respect to the motor vehicle body.
  • Such systems include latch or catch members which interengage with each other and/or with retaining members, usually a cylindrical pin fixed, for example, to the vehicle body, and held in a closed position by resilient means, typically springs.
  • a push button provided with a keyhole, located on the lock or close to it, allows the latch member to be disengaged by acting on the resilient means.
  • a security device is usually provided to prevent unauthorised persons (thieves) from releasing the latch members, the device being unlocked either by the aforesaid key or by means of an electrically activated servomechanism which can be controlled by a remote control using, for example, infra red radiation.
  • the push button of the lock must then be pressed to open the tailgate, as already stated, thereby freeing the jaws and allowing the tailgate to be lifted manually.
  • the aim of the present invention is to provide a device which opens the tailgate to a point at which the air springs, with which tailgates are normally provided, cause it to open completely without the person opening the tailgate needing to use their hands when they are otherwise engaged.
  • the invention achieves the aforesaid aim by means of a device for opening the tailgate of motor vehicles, in particular motor cars, having the characteristics specifically referred to in the following Claims.
  • reference numeral 2 generally indicates the rear part of a motor car provided with a rear door or tailgate 4.
  • the tailgate 4 has two air springs for lifting the tailgate 4, only one of which indicated 6 is visible in the drawing, a similar air spring being positioned symmetrically on the opposite side of the body 2.
  • a pedal 8 operates the device which is the subject of the present invention, indicated II in Figure 1 and represented in detail on an enlarged scale in Figure 2.
  • Reference numeral 10 indicates the keyplate of a lock 12, having a keyhole 14.
  • a finger 16 projects from the keyplate 10 and contacts a plate or arm 18, the finger 16 being rotatable about an axis 20 substantially perpendicular to the body 22 of the motor vehicle.
  • the lock 12 includes a first latch member 24 engaged in a seat 26 in a second latch member 28.
  • a spring 30 holds the first latch member 24 against the second latch member 28 in a closed position. In this position, the second latch member 28 engages a pin 32 fixed to the body 22 of the motor vehicle.
  • the first latch member 24 and the second latch member 28 are rotatable about axes fixed relative to the body 22 and substantially perpendicular thereto.
  • a projection or wing 36 on the first latch member 24 contacts a finger 38 connected by a Bowden cable 40 to a third latch member 42 which cooperates with a fourth latch member 44 connected to the plate 18 by a Bowden cable 45.
  • the third latch member 42 and the fourth latch member 44 are rotatably mounted on a plate 46 fixed to the body 22 and are held in a closed position by a spring 48.
  • the third latch member 42 engages a pin or roller 50 fixed to a rod 52 which is movable vertically and carries the pedal 8.
  • the pin 50 is fixed to a first end of a rod 54 which carries a push-rod 56 at its second end, this push-rod being in contact with the tailgate 4.
  • the rod 54 is pivotably mounted on the body 22, its rotation being opposed by a spring 58.
  • the plate 46 has a slot 60 in which the pin 50 is slidable.
  • the device which is the subject of the invention functions as follows.
  • Figure 2 illustrates a situation in which the device is locked and the pedal 8 cannot be operated.
  • the Bowden cables can be replaced by lever mechanisms.
