Definitions

  • the invention relates to a hinge device for a motor vehicle hood.
  • It relates more precisely to a device comprising, for connecting to the body of a vehicle each of two opposite lateral ends of an articulated part of a hood, two elements forming rods which are articulated on the body and on the hood constituting a deformable quadrilateral.
  • the rod elements are rigid and their size and the location of their articulations on the body and on the cover are such that the deformation of the quadrilateral when the cover is raised causes a displacement of the articulated part. from the cover towards the free end thereof so as to prevent the edge of this articulated part from hitting a neighboring piece.
  • Certain arrangements are sometimes provided to limit the lifting of the hood to an average open position suitable for current access to the contents of the compartment covered by the hood, while an upper position of the hood can be reached by means of associated complementary means. to the articulation device. These additional means increase the cost of producing the device and generally involve action by the user to cancel and restore the limitation of lifting of the cover to its average position.
  • a balancing or compensating spring is preferably added to the articulation device to assist the lifting operation and possibly to keep the cover in the open position.
  • the invention aims to provide a hood articulation device which is simple while assisting the lifting up to an open position for current use, and allowing a wider occasional opening without action on additional means.
  • the device according to the invention is of the aforementioned type with elements forming rods which are articulated on the body and on the cover in constituting a deformable quadrilateral, the cover being liftable from a low closed position to one or the other of two stable open positions, respectively middle and upper; it is characterized in that one of the above elements being a rigid link, the other element 5 is a telescopic balancer assisting the lifting of the hood to said middle position where it reaches its maximum extension, while two integral stops of the body are suitable for respectively and alternately maintaining the rigid link in a first stable position where the cover can pivot on it between said low and medium positions, and in a second stable position where it maintains the cover in its reached upper position, from its middle position, by pivoting on the balancer in maximum extension.
  • FIG. 1 a part of a vehicle 1 of which a cover 2 has been lifted from a low position 2b of closure to an average position 2m of opening by pivoting about an axis A transverse to the vehicle and located near from the lower edge of a windshield 3, while in FIG. 2 the cover is shown in an upper position 2s where its pivot axis has been displaced at A ′, preventing the rear edge 4 from lifting up hood does not strike the windshield and / or a wiper blade 5 resting thereon.
  • This device comprises a rigid link 10 and a telescopic balancer 11 which are articulated on the same support 12 fixed to the body, and on the same knuckle 13 fixed to the cover, constituting a quadrilateral which is deformed during the raising or lowering of the hood, as shown 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, whose respective articulations with the support 12 and with the knuckle 13 are constituted by ball joints 17 and 18.
  • the means for fixing the support and the knuckle are for example screws, not shown, passing through holes 12a, 13a of these parts.
  • a rear stop 19 formed by folding a sheet constituting the support 12, and a front stop 20 fixed thereto by any known means are arranged so as to immobilize alternately and respectively the rod 10 in the rear stable position ( Figures 4 and 5) or in a stable position before (figure 6).
  • the balancer contains, as known, a metal or compressed gas spring which tends to extend it by sliding to a maximum extension, determined by an internal stop, where the spring is still sufficiently constrained to support and maintain the cover in its middle ( Figure 5) and upper ( Figure 6) open positions.
  • the balancer 11 In the lower position 2b of the cover (FIG. 4), the balancer 11 is kept compressed by locking the cover in the closed position where the knuckle 13 is substantially horizontal; the balancer is very inclined and pushes back the knuckle 13 and the upper part of the link 10 thus maintained in a stable rear position against the stop 10.
  • a lifting S1 of the cover after its unlocking, assisted or obtained by telescopic extension of the balancer 11, is effected by pivoting on the axis 16 (materializing the transverse axis A above) of the rod 10 still maintained in its stable position rear by the weight of the rear part of the hood and by the rearward thrust of the balancer.
  • This lifting reaches the average position 2m opening ( Figure 5) where the balancer 11 and the knuckle 13 are inclined substantially at 45 ° relative to the horizontal and approximately perpendicular to each other; this 2m position is determined by the maximum extension of the balancer, the spring of which is still sufficiently constrained to thereby maintain the hood.
  • a complementary lifting S2 of the cover to its upper position 2s is obtained by pushing the user upwards on the free end 21 of the cover, which makes the connecting rod 10 pivot forwards on its axis 15 at the same time as the knuckle 13 pivots on the ball joint 18 connecting it to the balancer 11 still maintained at its maximum extension thanks to its sufficiently constrained spring; the knuckle and the balancer are almost vertical when the cover reaches its upper position 2s determined by immobilization of the link 10 in its stable position before it is in contact with the fixed stop 20.
  • the lowering of the hood is obtained by exerting on its free end 21 a sufficient downward push, from the middle position 2m, to compress the balancer.
  • This device is inexpensive since the balancer is not added to the quadrilateral but is part of it, and it allows easy manipulation of the cover, whether to obtain its current opening in the middle position or an exceptional opening in the upper position. . It can be applied both to a rear trunk lid of a vehicle and to a hood covering an engine compartment.
