Definitions

  • This invention relates to a device for controlling the opening of a door of a vehicle, especially for the bonnet of the vehicle.
  • the invention relates to a device according to claim 1, which is known from JP-A-58 004 673.
  • This document shows a device which permits to make a hood opening angle variable, including a telescopic gas spring having a first end articulated to the body of the vehicle and a second end articulated to the door and adjusting means to vary the opening arrangement of the door from a normal open to a more open position.
  • Said adjusting means include a sliding coupling between the second end of the spring and the door and a releasable stop mechanism.
  • DE-39 16 739 shows an articulation device for articulating a door to the body of a vehicle, including an articulated quadrilateral device.
  • the object of this invention is to produce a device of the type specified hereinabove which can be operated in a simple manner and is more compact and economical than the devices known hitherto.
  • the gas spring may be disposed in the lateral channels of the bonnet or the lid of the boot, reducing as far as possible the overall dimensions of the device.
  • the manually operable adjusting means allowing for passage from the normal open position to the more open position are situated at the point of articulation of the gas spring to the door and are thus in a readily accessible position.
  • the bonnet of a vehicle is articulated to the body 2 by means of an articulated quadrilateral mechanism 4.
  • the mechanism 4 comprises a lower flange 6 fixed to the body 2 and to which the lower ends of two arms 8, 10 are articulated.
  • the upper ends of the arms 8, 10 are articulated to an element 12 which is fixed to the bonnet 1 by means of a flange 14.
  • a pair of telescopic gas springs are interposed between the bonnet 1 and the body 2, only one of which can be seen in the drawings and is designated by the reference numeral 16.
  • Each spring 16 has a first end 18 articulated to the body 2 in the vicinity of the flange 6 and a second end 20 which is articulated to the bonnet 1 in the manner described hereinafter.
  • an articulation element 24 formed by a plate having a slot 26 is fixed to the free end of the rod 22 of the air spring 16.
  • the slot 26 is traversed by a pin 28 integral with the bonnet 1.
  • the pin 28 is free to slide along the slot 26 and to rotate relative to the hinge element 24 about its longitudinal axis A which constitutes the axis of articulation of the second end 20 of the air spring 16 to the bonnet 1.
  • a rocker arm 30 is pivoted on the articulation element 24 and cooperates with a pin spring 32 which holds it in the position shown in Figure 5.
  • the rocker arm 30 has a stop face 34 which bears against the pin 28 and prevents displacement thereof along the slot 26.
  • the rocker arm 30 has an integral actuating component 36 which can be actuated manually in order to oscillate the rocker arm 30 in the direction indicated by the arrows B against the return action of the spring 32.
  • the rocker arm 30 also has a cam surface 38, the function of which will be clear from the following.
  • the device is situated in the arrangement corresponding to the closed position of the door.
  • the pin 28 is located at the end of the slot 26 closer to the rod 22 of the air spring 16 and is held in this position by the rocker arm 30.
  • the articulation element 24 and the pin 28 are nevertheless free to execute a relative rotation about the axis A.
  • Figure 2 shows the normal open arrangement of the bonnet 1.
  • the pin 28 and the articulation element 24 are situated in the arrangement illustrated in Figures 1 and 5.
  • the angle of opening of the bonnet 1 is designated by the letter C and has a value of approximately 60 o .
  • the actuating component 36 of the rocker arm 30 is actuated manually, resulting in oscillation of the rocker arm in the directions indicated by the arrows B in Figure 5.
  • the pin 28 is free to slide along the slot 26 and is brought to the end of the slot further from the rod 22 of the air spring 16.
  • the arms 8, 10 execute a further rotation bringing them into the arrangement illustrated in Figure 3.
  • the angle of opening of the bonnet 1 is designated by the letter D and has a value of approximately 85 o .
  • the actuating component 36 of the rocker arm 30 In order to close the bonnet 1 starting from the more open arrangement, the actuating component 36 of the rocker arm 30 must be actuated, after which it is sufficient to push the bonnet downwards.
  • the pin 28 is thus moved along the slot 26 and cooperates with the cam surface 38 of the rocker arm 30, oscillating it in the direction indicated by the arrows B in Figure 5.
  • the rocker arm 30, displaced by the spring 32 returns to the stop position illustrated in Figure 5.

Claims (3)

  1. Dispositif servant à commander l'ouverture d'une porte d'un véhicule, particulièrement du capot du véhicule, comprenant :
    - des moyens (4) servant à articuler la porte (1) sur la caisse (2),
    - au moins un ressort à gaz télescopique (16) possédant une première extrémité (18) articulée à la caisse (2) et une deuxième extrémité (20) articulée à la porte (1), et
    - un moyen de réglage (26, 30) permettant de faire passer la configuration d'ouverture de la porte (1) d'une position d'ouverture normale à une position ouverte plus largement, le moyen de réglage (26, 30) comprenant un élément d'articulation (24) présentant une fente (26) dans laquelle un doigt (28) est monté coulissant, et un mécanisme de butée escamotable (30) adapté pour tendre à placer la deuxième extrémité (20) du ressort (16) dans une position relativement invariable par rapport à la porte (1),
    caractérisé en ce que les moyens d'articulation (4) comprennent un mécanisme à quadrilatère articulé comprenant deux bras (8, 10) dont chacun est articulé à la caisse (2) et à la porte (1) et en ce que ledit mécanisme de butée comprend un bras basculant (30) articulé à l'élément d'articulation (24) et possédant une face de butée (34) adaptée pour coopérer avec ledit doigt (28) pour le maintenir à une extrémité de la fente (26), ledit moyen de réglage comprenant un accouplement coulissant entre ladite deuxième extrémité (20) du ressort (16) et son axe d'articulation (A) sur la porte (1).
  2. Dispositif selon la revendication 1, caractérisé en ce que le mécanisme d'arrêt comprend des moyens élastiques (32) adaptés pour maintenir le bras basculant (30) dans la position dans laquelle sa face de butée (34) s'étend transversalement au passage du doigt (28) par rapport à l'élément de charnière (24).
