- the tailgate is movably mounted on the white body of the motor vehicle between an open position and a closed position. It is connected to the body by means of hinges located in the upper part of the box and by cylinders allowing the assisted opening thereof.
- the metal structure of the tailgate box allows it to comply with aesthetic specifications because its stiffening prevents it from deforming when it is in the closed position on the body.
- the metal structure also avoids fatigue that can lead to breakage of the box.
- each jack exerts a push on the tailgate placed in the open or closed position on the body.
- This thrust generating constraints in the tailgate it may deform, which is not acceptable for the aesthetics of the vehicle, especially when the tailgate is mounted in closed position on the body.
- the games and outcrops of the hatchback body parts with the surrounding body parts are indeed determined very precisely and must not be modified by the deformation of the tailgate.
- the present invention aims to provide a solution to this need, with a tailgate whose box is made mainly of plastic, including thermoplastic fiber reinforced material.
- a hatchback would comply with the aesthetic specifications with regard to the play and outcropping between the bodywork of the tailgate and the rest of the bodywork of the vehicle. It would also prevent fatigue resulting from the deformation of the tailgate and can lead to breakage of the box.
- the subject of the invention is a set of a motor vehicle body and a tailgate mounted movably on the body between an open position and a closed position, comprising: a mounted opening assistance means between the body and the tailgate so as to exert on the tailgate a thrust tending to place it in the open position; at least one stop arranged on the body for, when the tailgate is in the closed position, exert on the means of assisting the opening a force opposing its thrust, so that the tailgate does not suffer, or very attenuated, the thrust of the assistance means to the opening.
- a mounted opening assistance means between the body and the tailgate so as to exert on the tailgate a thrust tending to place it in the open position
- at least one stop arranged on the body for, when the tailgate is in the closed position, exert on the means of assisting the opening a force opposing its thrust, so that the tailgate does not suffer, or very attenuated, the thrust of the assistance means to the opening.
- the tailgate is less stressed by the thrust of the cylinders when it is placed in closed position on the body. Its rigidity can be reduced. It is then possible to lighten the tailgate while respecting the aesthetic specifications and mechanical strength of the vehicle.
- the stop is arranged so that the opening assistance means is in abutment on the stop when the tailgate is placed in closed position on the body.
- the reaction force exerted by the abutment on the opening assistance means thus makes it possible to oppose the thrust force of the means for assisting the opening.
- the assistance means for opening comprises a jack exerting a thrust along a given axis when the tailgate is placed in the closed position
- the opening assistance means may also comprise at least one connecting piece, preferably metal, connecting the cylinder to the tailgate, at least one surface of the abutment on which is able to rest the means of assistance to the opening is normal substantially parallel to the thrust axis.
- substantially parallel to the thrust axis is meant that the normal to the abutment surface is not inclined more than 45 ° relative to the thrust axis.
- At least one of the stops is arranged on the body so that at least one bearing surface the abutment intersects the thrust axis when the tailgate is placed in closed position on the body.
- the "bearing surface” is the surface of the abutment intended to be in contact with the jack or the connecting piece. This surface is not necessarily constituted by the entire face of the abutment.
- the thrust of the piston is not likely to give rise to a torque generating constraints in the tailgate; at least one of the stops is arranged so that one end of the jack is in abutment against the stop when the tailgate is placed in closed position on the body; at least one of the stops is arranged so that the connecting piece bears against the stop when the tailgate is placed in closed position on the body.

- At least one of the stops comprises a groove in which a substantially complementary projection of the groove, integral with the connecting piece, is adapted to engage when the tailgate is placed in closed position on the body.
- the connecting piece is stationary in rotation, at least in a direction perpendicular to the tailgate due to the presence of the groove.
- the torque does not deform the connection piece in torsion.
- the tailgate does not move in relation to its original position; the abutment is formed on the box by stamping.
- the manufacturing costs of the abutment are very low since its manufacture does not require any additional specific step, this being formed at the same time as the rest of the box. It can also be reported, for example by welding on the body; the tailgate comprises a box made at least partially of plastic, in particular thermoplastic material, in particular reinforced, such as polypropylene reinforced with glass fibers, which allows to substantially lighten the motor vehicle.
- the invention also relates to a white box of a motor vehicle belonging to the assembly according to the invention.

- Figure 2 is a perspective view of a detail of a set of the body and the a tailgate according to one embodiment of the invention, when the tailgate is placed in an open position of a few degrees on the body
- Figure 3 is a perspective view of the assembly of Figure 2, when the tailgate is placed in closed position on the body
- Figure 4 is a perspective view of a detail of an assembly according to another embodiment of the invention, when the tailgate is placed in closed position on the body.
- FIG. 1 shows the rear of a motor vehicle structure 10 constituted by the white body of this motor vehicle.
- the body 10 comprises in particular two rear uprights 12 delimiting the rear of the vehicle, and a roof pillar 14 delimiting the upper part of the vehicle.
- a hatch 16 forming opening of the vehicle, consisting of a tailgate box covered by body parts and a rear window.
- This hatch 16 is mounted movably on the body between an open position and a closed position. It is connected to the white box 10 by means of hinges 18 placed at the upper end of the tailgate and by jacks 20, located on each side of the tailgate and to assist the opening thereof.
- Each cylinder 20 comprises a frame 22, one end 24 is connected to the body and is rotatable relative to the body.
- a piston 26 is engaged in this frame 22, so that the piston is movable in translation relative to the frame 22 along an axis corresponding to the longitudinal axis X of the jack.
- Each cylinder 20 exerts on the tailgate a steering thrust corresponding to the axis of translation of the piston, tending to place the tailgate in the closed position in the closed position.
- the piston 26 is connected to the tailgate 16 via an end 28, opposite the end 24 of the frame.
- the end 28 of the piston is connected to a connecting piece 30 of longitudinal direction substantially perpendicular to the axis of translation of the piston, regardless of the position of the tailgate.
- This piece 30 is also fixed on the side of the tailgate box, by means of screws 32.
- the connecting piece 30 comprises a cone-shaped body 34 and comprises at its end a plate 36, the latter being fixed on the tailgate using screws or rivet 32.
- the connecting piece 30 also has at its end opposite to the plate a convex shape such that a The end 28 of the piston forms a concave portion intended to cooperate with the ball carried by the connecting piece, for example by clipping on it.
- the upright 12 of the box is formed at its rear end by a profile having a generally U-shaped shape and comprising a bottom 38 and two lateral walls 40.
- the tailgate consists of a box 42 forming at its end a U-shaped section 44, on which is glued a rear window 46, so that the tailgate forms at this location hollow stiffening body.
- the tailgate box is made of plastic material, especially reinforced thermoplastic material, such as polypropylene reinforced with glass fibers.
- the bezel is usually made of glass.
- the white box further comprises a stop 48, formed by stamping, along with the rest of the box.
- This abutment comprises an upper face and four lateral faces connecting the upper face to the rest of the body.
- this stop serves as a support for the connecting piece 30 when the tailgate box 42 is placed on the body 12 in the closed position.
- the connecting piece 30 is supported on a lateral face of the abutment facing upwards from the vehicle and normal substantially parallel to the axis of translation of the piston when the tailgate is placed on the body 12 in the closed position. In this way, the force exerted by the stop on the piston opposes the pushing force of the piston on the tailgate. Stresses due to the thrust of the piston are not transmitted to the tailgate, whose rigidity can be reduced.
- FIG. 4 shows a detail of an assembly according to another embodiment of the invention.
- the references are identical with those of FIGS. 2 and 3 if the objects designated by these references are identical.
- the body 49 and the tailgate box 42 are also connected via the cylinder 20 comprising a piston 26.
- the piston is connected to the tailgate box 42 via a connecting piece 51 .

- the connecting piece 51 comprises a flange 58 shaped to engage in the grooves 54 and 56, whose dimensions are substantially complementary to those of the groove. This flange is located on a median part of the body of the connecting piece 51 and positioned so that it is able to engage in each of the grooves.
- the body of the connecting piece is in contact with the lateral face of the abutment 50, this face producing a reaction force on the connecting piece adapted to oppose the thrust of the piston.
- This face is normal substantially parallel to the axis of translation of the piston, corresponding to the thrust axis.
- the reaction force exerted by the abutment on the connecting piece opposes the thrust force. It is however likely to create in combination with the pushing force a torque causing a twisting of the connecting piece and, therefore, a poor positioning of the tailgate.
- the connecting piece 30 can not twist and the tailgate remains correctly positioned.
- a beveled shape of the edges of the flange and a corresponding shape of the groove carried by the abutment can facilitate the beginning of engagement of the flange and its holding in position.
- the lateral faces of the abutments 50, 52 are of normal slightly inclined relative to the direction of the thrust axis, to ensure a better implementation of the connecting piece between the stops when closing the tailgate, without damaging the piece or one of the stops.
- the body comprises a stop located in the axis of translation of the piston, corresponding to the axis of thrust, when the tailgate is placed on the body in the closed position.
- the end of the piston is intended in this case to rest on one face of the abutment in this position.
- No torsional stress is transmitted to the body because the two forces are essentially collinear.
- the stop is not necessarily formed with the body and can be reported on the piece by gluing, welding or any other means.
- the shape of the abutment, the groove or the collar are not limited to those described.
- the connecting piece can also be reported on the body by other means than those described.
- the invention can also be implemented for a tailgate box which is shaped in a material other than a thermoplastic material, for example a thermosetting material.
