- the seal 51 is arranged over the entire perimeter of the opening 50, in particular on or at the level of a rebate 52 of the opening 50.
- the upper arm 10 is pivoted around the axis 34. Due to the cooperation of the movement transformation means 30, namely the helical groove 32 formed in the first cooperating element 31 with the axis or guide pin 36 extending from the carriage 42, the arm 10 rises or falls.
- the passage from the closed position PF to the open position PO of the door which corresponds to the pivoting of the arm associated with its descent thanks to the means 30 on the range of the angle p and its translation towards the rear along the rail, constrains, deforms, stretches, presses on a first portion 81 of the flexible interior covering 80 (hatched area from the front to the rear of the vehicle up to a border 84 illustrated with dots).
- the passage from the open position PO to the fully open position POT of the door which corresponds to the translation following the guide 41 (the arm remaining pivoted by the angle P) constrains, deforms, puts in tension, supports on a second portion 82 of the flexible interior covering 80 (hatched area from the border 84 illustrated in dotted lines towards the rear of the vehicle).
- a third portion 83 of the flexible interior covering 80 finds itself stretched, deformed, constrained.
- the deformed portions 81, 82 are illustrated in particular in Figure 5, the door 3 then being in the open position PO or POT or between these two positions.
- the portions 81, 82 of the flexible interior covering 80 come in turn into contact with a lower surface 18 of the upper arm 10.
- the lower surface 18 is shaped so as to limit wear of the edge of the covering 80 at the level of portions 81, 82, this edge being in contact with the arm.
- the portions 81, 82 are illustrated in dotted lines when the door is closed PF (the arm extending forward in the longitudinal direction and not interfering with the flexible interior covering - not illustrated).
- the flexible interior covering 80 of pavilion 8 is made of textile, in particular of fabric type, for example of textile of natural origin and/or of chemical origin.
- the flexible interior covering is obtained in another material, preferably having properties similar to fabric.
- the J1 stroke is defined by taking into account the possibilities of deformation of the flexible interior covering.
- the opening cycle starts from the closed position PF of the door 3.
- PF the closed position of the door 3.
- it is a lower device 20 which drives the movement of the upper arm 10.
- a step is taken to move from the closed position PF to the open position PO of the door 3 by pivoting the upper arm 10 around the pivot axis 34 of the transformation means 30, as illustrated by the pivot stroke of angle p in Figure 8.
- the transformation means 30 causes a descent of the upper arm 10 simultaneously, or substantially simultaneously, with this pivoting. The descent takes place over a stroke equal or substantially equal to the clearance J1 present between the first element 31 and the yoke 33.
- the pivoting of the upper arm 10 is stopped, for example by contact of the guide pin 36 against the upper end of the groove 32.
- the pivoting is then blocked in position so as to prevent any angular movement of the upper arm 10.
- the carriage 42 moves along the rail 41, preferably up to the rear end stop 44 (see Figure 8).
- the second portion 82 of the interior covering 80 facing the upper arm is moved downwards, folded, constrained, tense, by contact with the lower surface 18 of the upper arm.
- a step is carried out to move from the fully open position POT to the open position PO by translation via the sliding means and/or bearing 40.
- the upper arm 10 does not pivot during this translation.
- the carriage 42 moves along the rail 41, preferably from the rear end stop 44 towards the front.
- the second portion 82 of the interior covering 80 facing the upper arm is moved downwards, folded, constrained, stretched, by contact with the lower surface 18 of the upper arm.
- a passage step is carried out to the closed position PF of the door 3 by pivoting of the upper arm 10 around the pivot axis 34 of the transformation means 30, as illustrated by the stroke of pivoting angle p in Figure 8.
- the transformation means 30 causes the upper arm 10 to rise simultaneously, or substantially simultaneously, with this pivoting. The rise takes place over a stroke equal or substantially equal to the clearance J1 present between the first element 31 and the yoke 33.
- the first portion 81 of the interior covering 80 facing the upper arm 10 returns to its unfolded, unconstrained, relaxed shape, in the absence of contact with the lower surface 18 of the upper arm.
- the arm is translated forwards at its first articulation means 11 via the shuttle 42, preferably until it comes into contact with the end of stroke stop 43.
- the second articulation means 12 arranged between the arm 10 and the door 3 comprises a means for taking up play in the vertical direction. Indeed, it is appropriate not to transmit the descent or rise of the upper arm 10 during its pivoting to the door 3.
- the second articulation means 12 comprises a yoke 13 provided with an axis 14
- the end 16 of the upper arm 10 arranged within the yoke 13 leaves a clearance J2.
- a spring 15 for example of the helical spring type arranged around the axis 14 within the yoke 13, makes it possible to facilitate the raising of the upper arm if necessary.
- games J1 and J2 are identical or substantially identical.
- the solution is based on an upper arm 10 with helical pivoting, that is to say translating in the vertical direction during its pivots. Furthermore, simultaneously with these pivots, the upper arm 10 is translated in the longitudinal direction.
- the solution is particularly suitable for a rear door of a private vehicle, in particular a framed rear door. More precisely, the solution makes it possible to install a mechanism for maintaining the top of the door 3 while having a significant roof drop and/or a prominent rebate 52.
- the solution is compatible with a lower mechanism which supports the door 3 and drives it in the opening and closing kinematics. closing.
- the upper arm is able to follow the movements of the door imposed by the lower device 20 without creating a hard point.
- the upper arm 10 completed by the transformation means 30 and the sliding and/or rolling means 40 adapts to the kinematics of the lower device 20, being a "slave", follower, of the lower device 20.
- the lower device 20 can thus be motorized, in particular by an electrical system, the upper arm of the door not hindering the kinematics.
- the lower device 20 is preferably of the pantograph type for example, or equivalent, and does not accept, or only little, movements in the vertical direction of the door or pivoting around axes extending transversely.
- the upper rail or guide 41 arranged within the cavity 71 of the stretcher lining is substantially invisible, even during openings/closings of the door, in particular due to the presence of the interior covering flexible 80.
- the rail 41 is also not visible from inside the vehicle. This results in an aesthetic improvement of the vehicle both from the inside and the outside.
- the upper guide 41 extends longitudinally and therefore does not impact habitability.
- the kinematics of the door include lateral movements of the door 3 although the guide 41 does not have a curved end extending within the passenger compartment.
- the guide 41 extends longitudinally, without presenting any curvature, which is a guarantee of saving space within the passenger compartment.
- the solution offers a concomitance of the pivoting of the upper arm 10 with the movement in the vertical direction of the arm and, preferably, with the translation of the arm in the longitudinal direction. This results in improved accessibility on board the vehicle, while retaining the geometry of the initial body side opening where applicable, that is to say without reducing the access area within the vehicle. Access within the opening 50 is therefore not impacted, or is even optimal, maximized. Indeed, the solution allows the upper arm to deviate downwards, to lower relative to the upper rebate 52 of the opening 50, as illustrated in particular in Figure 3. Thus, although this rebate is extends by lowering towards the rear, in particular to follow the roof also lowering towards the rear, the arm does not interfere with the rebate and passes under it.
- the solution makes it possible to have a sliding rear door while the body includes a roof drop, or roof curve not parallel to the transverse and longitudinal directions, (roof lowering towards the rear of the vehicle) and/or a upper edge of rear door lowering towards the rear of the vehicle.
- the body architecture and/or aesthetics improved by this roof drop are then compatible with a sliding rear door.
- the rail extends longitudinally within the vehicle so as to obtain movement of the door without descent or rise, parallel to the ground, while having a body including a roof drop.
- the solution allows a sliding door kinematics comprising a pivoting and a translation compatible with a vehicle provided with a roof drop at the level of the rear doors, while arranging the upper guide at the level of the roof and hiding the upper guide during changes in position of the sliding door.
- the possible fall of the flag in terms of angle relative to the horizontal is of the order of 8 degrees, or even more, for example of the order of 25 degrees.
- the solution makes it possible to create a clearance, a stroke, a movement in the vertical direction of the upper arm 10 so as to avoid any contact, any interference, of the upper arm 10 against the rebate 52 of the opening 50 during the translation phases, particularly of the door.
- the solution also makes it possible to arrange the longitudinal guide part inside the vehicle itself, within the stretcher lining 70, behind the stretcher covering 9. This allows compatibility with a sliding door 3 with frame while having of a pronounced fall of the roof and by limiting the intrusion into the passenger compartment of the sliding door guide system.
- the shape of the groove 32 determines the start and/or end of translation of the upper arm downwards and/or upwards.
- a groove 32 as illustrated in Figure 11 generates a downward translation of the upper arm from the start of door opening, that is to say from the start of pivoting of the arm, and the case possibly, simultaneously with a movement of the carriage 42 along the rail 41.
- a lower part 32' (dotted lines in Figure 11) of the guide surfaces 39 of the groove 32 extends obliquely upwards.
- the kinematics are linked to the lower device 20 which is leading, in particular equipped with a pivoting pantograph system, which causes that the start of opening simultaneously generates the pivoting of the upper arm and the movement towards the rear of the carriage 42 in the rail 41.
- the upper part 32” (solid lines in Figure 11) of the guide surfaces 39 of the groove 32 extends in a transverse and longitudinal plane or substantially in such a plane. This results in the end of pivoting of the upper arm 10 when opening the door has no consequence in terms of movement in the vertical direction of the upper arm. Consequently, the start of pivoting of the arm, when closing the door, has no effect on the arm in the vertical direction.
- the solution therefore achieves the desired objective of providing an arrangement comprising a sliding rear door with a frame tolerating a significant roof drop, without encroaching on the habitability or accessibility of such a vehicle, and has the advantage to be able to be used on other types of vehicles, namely trucks, buses, coaches or even aircraft.
