Definitions

  • the invention relates to a hinge device for a hood. motor vehicle.
  • It relates more precisely to a device comprising, for connecting at the body of a vehicle each of two opposite lateral ends of an articulated part of a cover, two elements forming rods which are articulated on the body and on the hood constituting a quadrilateral deformable.
  • the elements forming rods are rigid and their dimension and the location of their joints on the body and on the hood are such that the deformation of the quadrilateral when the hood is raised causes a displacement of the hinged part of the cover towards the free end thereof so as to prevent the edge of this articulated part from hitting a part neighboring.
  • Certain arrangements are sometimes provided to limit the hood raised to a suitable open position for current access to the contents of the compartment covered by the cover, while an upper position of the cover can be reached by means of additional means associated with the articulation device. These additional means increase the cost of producing the device and usually involve user action to cancel and to restore the hood lift limitation to its middle position.
  • a balancing or compensating spring is preferably attached to the articulation device to assist the maneuver lifting and possibly to keep the hood in position opened.
  • the invention aims to produce a hood articulation device which is simple while assisting lifting to an open position for everyday use, and allowing a wider opening occasional without action on additional means.
  • the device according to the invention is of the type mentioned above.
  • connecting rod elements which are articulated on the body and on the cover in constituting a deformable quadrilateral, the cover being liftable low closing position in either of two stable positions aperture, respectively medium and superior; it is characterized by that one of the above elements being a rigid rod, the other element 5 is a telescopic balancer assisting the lifting of the hood up to the so-called average position where it reaches its maximum extension, while two stops integral with the body are suitable for maintaining respectively and alternatively the rigid rod in a first stable position where the cover can pivot on it between said positions low and medium, and in a second stable position where it maintains the cover in its upper position reached, from its position medium, by pivoting on the balancer in maximum extension.
  • This device comprises a rigid link 10 and a balancer telescopic 11 which are articulated on the same support 12 fixed to the body, and on the same knuckle 13 fixed to the cover by constituting a quadrilateral deforming when the hood is raised or lowered, as indicated below.
  • the link is articulated by transverse axes 15 and 16 respectively on the rear ends of the support 12 and the knuckle 13 thus being closer to the rear edge 4 of the cover than the balancer 11, of which the respective articulations with the support 12 and with the knuckle 13 consist of ball joints 17 and 18.
  • the means for fixing the support and knuckle are for example screws, not shown, passing through holes 12a, 13a of these parts.
  • a rear stop 19 formed by folding a sheet metal constituting the support 12, and a front stop 20 fixed thereto by known means any are arranged so as to immobilize alternately and respectively the rod 10 in rear stable position ( Figures 4 and 5) or in the stable front position ( Figure 6).
  • the balancer contains, as known, a metal or gas spring tablet which tends to stretch by sliding to an extension maximum, determined by an internal stop, where the spring is still sufficiently constrained to support and maintain the hood in its middle (figure 5) and top (figure 6) opening positions.
  • the balancer 11 In the lower position 2b of the cover (FIG. 4), the balancer 11 is kept compressed by locking the hood in the closed position where the knuckle 13 is substantially horizontal; the balancer is very tilted and push back the knuckle 13 and the upper part of the link 10 thus maintained in a stable rear position against the stop 19.
  • the hood is lowered by exercising on its free end 21 sufficient downward push from the middle position 2m, to compress the balancer.
  • This device is inexpensive since the balancer is not added not at the quadrilateral but is part of it, and it allows manipulation easy hood, whether to obtain its current opening in medium position or an exceptional opening in the upper position. It can be applied to a rear trunk lid as well than a cover covering an engine compartment.
