Definitions

  • the present invention relates to a device opening joint according to the preamble of claim 1.
  • Such a device is for example described and shown in document FR-A-2.717.213.
  • Such a design makes it possible in particular to ensure the articulation of a vehicle tailgate whose handling requires little effort to switch from the closed position to an open position and which can be manipulated without significant effort from the position closed until fully open.
  • articulation device of the tailgate in particular of a tailgate of a vehicle, is of the type comprising accumulation means energy constituted for example by a spiral spring, which store energy in the closed position and restore this in the form of a balancing torque during the opening to compensate for the resistance torque due to the mass tailgate.
  • the balancing torque that compensates for the torque resistant therefore gradually decreases by a maximum value corresponding to the extreme closed position towards a value minimum corresponding to the extreme open position, this progressive decrease, linear or not, of the balancing torque being due to the progressive relaxation of the spiral spring.
  • Document FR-A-2,739,349 has proposed hinge device of the type described and shown in the document mentioned above for the articulation and the balancing of an opening, in particular vertical, that is to say an opening which extends substantially in a vertical plane in closed position, of which the curve of the resistant torque to balance has very small values of the resistive torque in one of the extreme positions, and in particular in position closed, this resistant torque in the extreme position can possibly be zero.
  • this last document proposes a device of articulation in which the balancing means compensate substantially the entire resistive torque along its swivel stroke, and the value of the balancing torque passes through a maximum at an intermediate point of the race pivot.
  • Such a design of the articulation devices and balancing, using fixing means on the opening, or tailgate, which are generally arranged below of the vehicle seat belt, allows remove the structure of the opening which is located above the vehicle seat belt, i.e. in particular remove most of the window frame arranged in the upper part of the opening above the beltline.
  • This upper glazed part of the opening also called rear window, can thus be reduced in thickness and in volume.
  • the bezel is retained at the top when the door is in the closed position, while providing means for stopping the opening opening limit switch.
  • the invention provides a device hinge of an opening, in particular a tailgate, mounted pivoting on the body of a motor vehicle, in particular between a first extreme closed position in which it extends in a substantially vertical plane and a second extreme open position in which it extends in a plane substantially horizontal above the vehicle, by through a two-axis hinge mechanism parallel transverse connected by two longitudinal connecting rods articulation parallels, each of which has a first front end articulated on the body around a first axis of articulation and a second articulated rear end the tailgate around a second articulation axis carried by the tailgate, and of the type in which the tailgate is formed by a panel masking a recess in a frame of the structure delimited by at least one lower cross member and by two lateral uprights each of which carries an axis of articulation of the tailgate of which the other rear end is articulated on a hinge pin, characterized in that the front end of at least one connecting rod carries a tailgate retention bolt, hook-
  • FIG. 1 shows a side view of the rear part of a motor vehicle 10 whose body 12 is open at the rear to allow access to the passenger compartment 14 of the vehicle and for example its load.
  • the opening is delimited by a frame essentially consisting of two vertical lateral uprights one of which 16 is represented in FIG. 1, the lateral upright opposite 17 being arranged symmetrically with respect to the plane longitudinal median of symmetry of the vehicle, and by two upper cross 18 and lower 20 which define a recess, the closure of which is ensured by an opening 22, also called a tailgate, which has a window or bezel 23 in the upper part and which is generally mounted pivoting relative to the structure of the body 12 of the vehicle, around a horizontal axis.
  • the tailgate 22 is shown in the closed position on the Figure 1 in which it extends substantially in a plane vertical, and it is shown in the maximum open position on Figure 3 in which it extends in a plane substantially horizontal, partly above the upper side of the vehicle roof.
  • the opening 22 is mounted swiveling on the body 12 by a two-axis system horizontal articulation A1 and A2 thanks to a articulation mechanism with two parallel connecting rods 24, 26 of which one 24 is illustrated in FIGS. 1 and 2.
  • the articulation device of the tailgate 22 on the body 12 of the vehicle preferably consists of two connecting rods or arms parallels 24 and 26 which are stamped sheet metal parts of which the front ends 28, 30 are articulated on the body 12 around a first transverse horizontal axis A1 and whose rear ends 32, 34 are articulated on the tailgate 22 around a transverse axis A2 parallel to the axis A1.
  • the horizontal axis A1 is fixed relative to the body structure 12 of the vehicle 10.
  • a device for closing and locking is arranged in the lower part and it is for example constituted by a fixed strike 36 on which hangs a bolt 38 carried by the tailgate 22, these components being illustrated schematically in Figures 1 and 3.
  • a fixed plate plate 40 which is fixed to the associated lateral upright 16 and which, comments see it in figure 7 and according to a design general known from the previously mentioned documents, constitutes one of the faces of a fixed housing 42 which is in particular supplemented by another parallel plate 44.
  • the housing 42 receives various components belonging in particular to means for balancing the tailgate mass 22, more particularly a spiral spring 46 which is mounted around a rod 48 which passes through an internal sleeve 50 of the housing 42, of axis A3 parallel to axis A1, on which is rotatably mounted a pinion 52 which cooperates, in a manner known from the document FR-A-2.739.349, with a toothed sector 54.
  • the front end part 28 of the connecting rod 24 is shaped like a hollow box 56 delimited by two plates 58 and 60 parallel and perpendicular to the axis A1, the plate 60 extending, as can be seen in particular in FIG. 7, in part under the fixed plate 40 of the housing 42 transversely to inside the latter.
  • the two plates 58 and 60 are crossed by a welded sleeve 62 which rotatably receives a tubular sleeve internal 64 which is crossed by a screw 66 whose end threaded 68 passes through a toothed pinion body 70 made of material with the sleeve 64 and which is fixed axially and in rotation on the thick part opposite 43 of the fixed plate 44 of the housing 42.
  • the screws 48 and 66 allow the housing to be fixed 42 on the amount 16 of the vehicle.
  • the sleeve 62 - and therefore the front end 28 of the connecting rod 24 - is rotatably mounted around the geometric axis A1, with respect to the fixed housing 42 - and therefore with respect to the fixed plate 40 - so that a rack 72 carried by the connecting rod 24 cooperates with the fixed pinion 70 so as to control, in a known manner, the rotary movement of the tailgate 22 around its axis of articulation A2 as a function of the movement of rotation of the connecting rod 24 relative to the body 12, 40 of the vehicle 10.
  • the free end 74 of the threaded rod 48 projects the outside of the housing 42 to constitute a pin 74, of axis A3, which is covered with a flexible roller made of elastomeric material or rubber 76, the function of which will be described later.
  • the front end 28 of the connecting rod 24 carries a bolt 80 which is a hinged mounted on the connecting rod 24 around a geometric axis A4 which is parallel to the axes A1 and A2, and around which the bolt 80 can pivot in both directions of rotation.
  • the bolt or latch 80 is a generally plate-shaped part thick which is parallel to the plates 58 and 60 of the connecting rod 24 and which has two concentric sleeves, interior 84 and outside 86, the first of which receives a rod 88 in rotation welded to plate 58 and the second of which delimits with the inner sleeve 84 a cylindrical housing receives the body 88 helically wound with a return spring 90 which is a spring in wire with two branches 92 and 94.
  • the second branch 94 is received in a housing 96 of the bolt 80 while the first branch 92 permanently cooperates with the end free 98 of a cylindrical pin 100 which is parallel to the rod 88, of axis A5, and which is welded to the plate 58.
  • the return spring 90 is designed to stress resiliently permanently the bolt 80 clockwise considering Figures 2, 4 and 8.
  • the cylindrical pin 100 is also coated with a sleeve 102 which constitutes an elastic stop capable of cooperate with a rear edge 104 bolt 80.
  • the bolt 80 is shaped as a hook 108 and it is capable of cooperating with a cylindrical pin 110 which is a fixed pawn, of geometric axis A6 parallel to the others previously mentioned axes, and which is carried by the associated vertical side upright of the tailgate, the pin being secured to the side pillar of the tailgate window.
  • the hook 108 is open in the front edge 112 of the bolt 80 and it is delimited by two parallel edges in an arc of circle which are spaced by a corresponding distance substantially to the diameter of the retention pin 110 so that the latter can move in the light forming hook 108.
  • the retention pin 110 is mounted at rotation, around a geometric axis A7 parallel to the others axes, on the tailgate.
  • the bolt 80 has a front edge forming a cam 114 which is capable of cooperating with a fixed finger 116 carried by the fixed plate 40.
  • the front edge forming a cam 114 is designed to cooperate with the fixed control finger 116 and it comprises this effect a notch 120 in which the fixed finger of command 116 is likely to penetrate.
  • the fixed stop 76 Prior to its penetration into the light forming hook 108, the fixed stop 76 cooperates with the front edge forming cam 114 of the articulated bolt 80 along which the roller stop 76 rolls gradually. Because of its ability to deform elastically, the stop 76 is compressed and it constitutes a brake on the inertia of opening of the system caused by an overbalance of the opening assistance.
  • roller stop 76 After passing this braking zone, the roller stop 76 is housed in the hook cavity 108.
