Description

Title of the invention: Arrangement for a vehicle comprising a body side without a center pillar, a hinged front door and a substantially hinged rear door. Technical field of the invention

[0001] The invention relates to an arrangement for a vehicle comprising a body side without a center pillar, a hinged front door and a substantially hinged rear door. The invention also relates to a body comprising such an arrangement. The invention also relates to a vehicle comprising such an arrangement or such a body. State of the prior art

[0002] A vehicle, in particular a van-type motor vehicle, generally comprises a body side allowing wide access within the vehicle. To maximize lateral access, a B-pillar is generally dispensed with between a front side door and a rear side door. However, in the case of hinged front and rear doors, i.e. pivoting around vertical axes, the absence of a B-pillar generates an order to open, and consequently to close, such doors. Generally, prior opening of the front door is necessary to open the rear door. In other words, the front door is leading, and the rear door is driven. This results in disadvantages. In particular, a rear passenger cannot exit the vehicle or access the vehicle through a rear door without opening the adjacent front door.

[0003] This situation is neither acceptable in terms of ergonomics, nor acceptable in terms of safety. Presentation of the invention

[0004] The object of the invention is to provide an arrangement which overcomes the above drawbacks. In particular, the invention provides an arrangement which makes it possible to prevent a front seat belt from hindering exit or access via a rear door adjacent to such a front seat belt. Summary of the invention

[0005] To achieve this objective, the invention relates to an arrangement for a vehicle, in particular for a motor vehicle, the arrangement comprising: - one side of the body, - a hinged front door and a substantially hinged rear door, a rear edge of the front door being adjacent to a front edge of the rear door in the closed position of the front and rear doors, the front door being pivotally mounted relative to the body side about a vertical or substantially vertical front axis arranged at a front edge of the front door, the arrangement comprising at least one double hinge, preferably two double hinges, each double hinge comprising a first vertical or substantially vertical axis for pivoting between the double hinge and the body side, each double hinge comprising a second vertical or substantially vertical axis for pivoting between the double hinge and a rear edge of the rear door, so that the front door can be opened while the rear door is closed and so that the rear door can be opened while the front door is closed.

[0006] The body side may include: - an upper rail arranged in the upper part of the body side, the rear door being able to comprise an upper rolling and / or sliding means intended to cooperate with the upper rail, and - a lower rail arranged in the lower part of the body side, the rear door being able to comprise a lower rolling and / or sliding means intended to cooperate with the lower rail, so as to cause a translation of the rear door at the start of opening and at the end of closing of the rear door.

[0007] The upper rail and the lower rail may each extend horizontally and in a vertical plane oriented towards the inside and towards the front of such a vehicle, in particular the upper rail and the lower rail extend in the same plane.

[0008] The rear door may comprise a main transverse locking means, in particular a fork extending in a transverse and longitudinal plane, in particular at the level of the upper rolling and / or sliding means, and the body side may comprise a main transverse locking means, in particular a finger extending vertically, in particular in the upper part of the body side, so that the main transverse locking means of the rear door cooperates with the main transverse locking means of the body side in the closed position of the rear door.

[0009] The rear door may comprise a secondary transverse locking means, in particular a cylindrical finger extending in a transverse and longitudinal plane and being oriented towards the front and towards the inside of such a vehicle, in particular at the level of the lower rolling and / or sliding means, and the body side may comprise a secondary transverse locking means, in particular a cylindrical hole comprising a damping means, in particular in the lower part of the body side, so that the secondary transverse locking means of the rear door cooperates with the secondary transverse locking means on the body side in the closed position of the rear door.

[0010] The double hinge may comprise a locking means in an intermediate opening position of the rear door, the locking means being able to stop the pivoting between the double hinge and the body side after a passage from a closed position of the rear door to the intermediate opening position by pivoting the double hinge around these first and second axes so that the pivoting between the double hinge and the rear door takes over to open the rear door further, and the locking means may prevent pivoting between the double hinge and the body side between a rear door opening position, in particular a fully or substantially fully open position of the rear door, and the intermediate opening position of the rear door during closing of the rear door.

[0011] The front door may comprise attachment means for a first front seat belt end and / or for a front seat belt retractor and / or for a second front seat belt end.

[0012] The invention also relates to a vehicle body, in particular a motor vehicle, comprising an arrangement as defined previously on a right side and / or on a left side of the body.

[0013] The invention also relates to a vehicle, in particular a motor vehicle, comprising a body as defined previously, or at least one arrangement as defined previously.

[0014] The rear door may have a degree of opening relative to the body side which is greater than 90 degrees and / or less than 180 degrees, preferably of the order of 170 degrees. Presentation of figures

[0032] The direction in which a vehicle, in particular a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a direct XYZ reference frame is used in which X is the longitudinal direction in the front-rear direction of the vehicle, therefore directed towards the rear, Y is the transverse direction directed towards the right and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the vehicle usually moves in the longitudinal direction and is opposite to the rear direction.

[0033] Thus, in the following, "front" or "in front" refers to the front of the vehicle, "rear" or "behind" refers to the rear of the vehicle, "right" refers to the right side of the vehicle and "left" refers to the left side of the vehicle.

[0034] Note that the figures illustrate a right side of a vehicle.

[0035] As illustrated in [Fig.l], a vehicle 1, preferably a motor vehicle, comprises a body 3. The vehicle 1 is for example of the van type, utility or non-utility. For example, the vehicle 1 is a converted or non-converted van. The vehicle 1, or the body 3, comprises at least one arrangement 2. Preferably, the vehicle 1 comprises at least one front seat 4 that can be oriented and / or pivoted, preferably around a vertical or substantially vertical axis. For example, only the front passenger seat is pivotable. Alternatively, only the driver's seat is pivotable. Preferably the vehicle 1 comprises two front seats and both front seats are pivotable. Optionally, the vehicle 1 comprises three front seats, or even more, and at least one of them is pivotable.Such a front seat pivot allows the driver, if necessary, or a front passenger, to be seated, for example, towards the rear of the vehicle or substantially with their back to the road, like the front seats of a camper van type vehicle.

[0036] More precisely, the body 3 of the vehicle 1, or the vehicle 1, comprises the arrangement 2 on a right side, or on a left side, of the body 3, or even on each side.

[0037] The arrangement 2, or the body 3, comprises a body side 5 illustrated in particular in FIGS. 2 and 3. The arrangement 2 further comprises a hinged front door 10. The front door 10 comprises a front edge 11, for example substantially vertical, and a rear edge 12, for example substantially vertical. The arrangement 2 further comprises a rear door 20 which is substantially hinged. The rear door 20 comprises a front edge 21, for example substantially vertical, and a rear edge 22, for example substantially vertical.

[0038] The body 3, or at least one side of the body 5, does not include a middle pillar or pillar B. Thus, when the doors 10, 20 are open, the area of ​​the opening or access 6 within the passenger compartment is significant and corresponds approximately to the sum of the areas of the adjacent front and rear doors.

[0039] The rear edge 12 of the front door 10 is adjacent, or substantially adjacent, to the front edge 21 of the rear door 20 in the closed position of the front and rear doors 10, 20, as illustrated in [Fig. 2]. Note that the front door 10 is hinged, pivoting relative to the body side 5 about a front axis 15, vertical or substantially vertical, arranged at the level of the front edge 11 of the front door 10.

[0040] The arrangement 2 further comprises at least one double hinge 30 illustrated in particular in FIGS. 3, 11 and 12. By double hinge is meant a hinge having two pivot or rotation axes. Preferably, the two pivot axes are parallel or substantially parallel. As illustrated in [Fig. 11], a double hinge 30 comprises a first axis 35 extending vertically or substantially vertically for pivoting between the double hinge 30 and the body side 5. The double hinge 30 comprises a second axis 32 extending vertically or substantially vertically for pivoting between the double hinge 30 and a rear edge 22 of the rear door 20. The first axis 35 is fixed relative to the body side 5 and the second axis 32 is fixed relative to the rear door 20. Advantageously, as illustrated in [Fig. 11], the first axis 35 is arranged behind the second axis 32 in the longitudinal direction of the vehicle.The double hinge 30 preferably comprises a connecting rod, or connecting rod, or arm 31 having an arcuate, or substantially arcuate, shape according to a section in a transverse and longitudinal plane. The connecting rod 31 comprises a first end 36 at the first axis 35 and a second end 37 at the second axis 32. Preferably, the connecting rod 31 comprises a first rectilinear portion 38 extending from the first end 36 and a second rectilinear portion 39 extending from the second end 37. The first rectilinear portion 38 and the second rectilinear portion 39 are parallel or substantially parallel and extend in vertical planes and oriented towards the inside and towards the front of the vehicle in the closed position of the rear door.For example, the portions 38, 39 of the connecting rod 31 extend in the longitudinal direction or substantially in the longitudinal direction in the intermediate opening position of the door 20 which will be seen later.

[0041] A pivoting is therefore possible around the first axis 35 between the first end 36 of the connecting rod 31 and the body side 5. Another pivoting is therefore possible around the second axis 32 between the second end 37 of the connecting rod 31 and the rear edge 22 of the rear door 20. These pivotings and the translation or sliding movements of the rear door 20 will be detailed later.

[0042] Thanks to the double hinge 30, the front door 10 can be opened while the rear door 20 is closed and the rear door 20 can be opened while the front door 10 is closed (see figures 5 and 6) as will be seen later.

[0043] As illustrated in Figures 15 and 16, the body side 5 preferably comprises an upper rail 51 arranged, for example fixed, on an upper part 50 of the body side 5. The rear door 20 then comprises an upper rolling and / or sliding means 25 at the top of the front edge 21 of the door 20. The means 25 is able to cooperate, that is to say to slide and / or roll on the upper rail 51. Preferably, the upper rail 51 has a substantially U-shaped section, the opening of the U being oriented towards the outside of the body side 5, such that the upper rail 51 is inclined at 90° relative to a vertical direction Z. The means 25 comprises at least one roller or caster 54 rolling against one of the parallel walls of the upper rail 51, namely against the lower wall of the U, as illustrated in [Fig. 16].In this case, the upper rail 51 mainly takes up vertical forces from the rear door 20, in particular forces linked to the weight of the rear door.

[0044] Preferably, as illustrated in Figures 13 and 14, the body side 5 comprises a lower rail 53 arranged, for example fixed, in the lower part 52 of the body side 5. The rear door 20 then comprises a lower rolling and / or sliding means 23 at the bottom of the front edge 21. The means 23 is capable of cooperating, i.e. sliding and / or rolling relative to, or on, the lower rail 53. Preferably, the lower rail 53 has a substantially U-shaped section, the opening of the U being oriented towards the outside of the body side, i.e. opposite the passenger compartment. The means 23 comprises for example at least one roller or caster 55 with an axis of rotation included in a longitudinal and transverse plane and preferably a front roller or caster 56 and a rear roller or caster 57 each having a vertical or substantially vertical axis, so as to roll and / or slide within the U of the rail 53 as illustrated in [Fig. 14].Thus, the lower rolling and / or sliding means 23 is for example of the mobile carriage type. In this case, the lower rail 53 mainly has a guiding role in the vertical direction via the contacts and / or bearings with the roller 55, and preferably takes up forces linked to the weight of the rear door 20. The lower rail 53 then also has a guiding role in the transverse direction via the contacts and / or bearings with the two rollers 56, 57.

[0045] Thanks to the cooperation between the rails 51, 53 and the rolling and / or sliding means 23, 25, the rear door 20 translates along the rails 51, 53. More precisely, it is the front edge 21 of the rear door 20 which translates at the start of opening of the rear door and at the end of closing of the rear door 20.

[0046] By "start of opening", we mean the passage between the closed position ([Fig.2]) of the rear door 20 and the intermediate position of the rear door 20 ([Fig.5]). By "end of closing", we mean the passage between the intermediate position of the rear door 20 ([Fig.5]) and the closed position ([Fig.2]) of the rear door 20. More precisely, the start of opening corresponds to the phase of translation, of sliding, of the front edge 21 of the rear door 20 relative to the rails 51, 53 during the opening of the rear door 20. The end of closing corresponds to the phase of translation, of sliding, in the opposite direction, of the front edge 21 of the rear door 20 relative to the rails 51, 53 during the closing of the rear door 20.

[0047] Preferably, the upper rail 51 and the lower rail 53 each extend in a vertical plane oriented towards the inside and towards the front of the vehicle as illustrated in Figures 14 and 16. Advantageously, the upper rail 51 and the lower rail 53 extend substantially in the same plane, at least in two parallel planes.

[0048] As illustrated in particular in Figures 15 and 16, the rear door 20 further comprises a main transverse locking means 40. Preferably, the main transverse locking means comprises a fork or fork 41 extending in a transverse and longitudinal plane. For example, this fork 41 extends at or near the upper rolling and / or sliding means 25. The body side 5 then comprises a main transverse locking means 45, for example a finger, an axle, a shaft, a rod 46 extending vertically for example. Preferably, this finger 46 is arranged, for example fixed, in the upper part 50 of the body side 5. Thus, at the end of closing of the rear door 20, the main transverse locking means of the rear door 20 cooperates with the main transverse locking means of the body side 5.In other words, the fork 41 comes to surround, on either side, the finger 46 at the end of closing of the rear door 20 and in the closed position of the rear door.

[0049] Preferably, as illustrated in Figures 13 and 14, the rear door 20 comprises a secondary transverse locking means 42 of the anti-opening or anti-lateral shift type of the rear door, in particular in the event of an impact, in particular a side impact. For example, the secondary transverse locking means 42 comprises a cylindrical finger, an axis, a rod 43, extending for example substantially in a transverse and longitudinal plane and being oriented towards the front and towards the inside of the vehicle. Preferably, this secondary transverse locking means is arranged, for example fixed, at or near the lower rolling and / or sliding means 23, for example behind this means 23 in the longitudinal direction. For example, this finger 43 extends from a rebate of the front edge 21 of the rear door and is arranged at the bottom of the rear door.The body side 5 then comprises a secondary transverse locking means 47, for example a cylindrical hole, a circular orifice, or even a bore 48, more or less deep within the body side 5. For example, the finger 43 and / or the hole 48 comprise a damping means 49, in particular in order to avoid slamming noises when closing the rear door. Preferably, the bore 48 is arranged in the lower part 52 of the body side 5. Thus, the means of . secondary transverse locking means 42 of the rear door 20 can cooperate with the secondary transverse locking means 47 on the body side 5 in the closed, or substantially closed, position of the rear door 20.

[0050] Note that the main locking means 40 of the door 20 associated with the main locking means 45 of the body side 5 aims in particular to ensure positioning, alignment, between the front edge 21 of the rear door 20 and the rear edge 12 of the front door 10 in the closed positions of the doors 10, 20 illustrated in [Fig. 2]. Note that the secondary locking means 42 of the door 20 associated with the secondary locking means 47 of the body side 5 aims in particular to ensure that the rear door 20 is kept in the closed position, that is to say to hook the body side in order to ensure that the rear door is kept in the closed, or substantially closed, position in the event of an impact on the vehicle, in particular in the event of an impact at the level of this rear door, at least at the level of this lateral side of the vehicle.

[0051] Advantageously, as illustrated in [Fig. 11], the double hinge 30 comprises a locking means 33 in an intermediate opening position of the rear door 20. Note that the intermediate opening position of the rear door 20 illustrated in FIGS. 5 and 8 corresponds to the position obtained after the simultaneous pivoting around the axes 32, 35 of the double hinge 30 simultaneously with the translations along the two rails 51, 53 of the means 25, 23. Thus the intermediate position of the rear door 20 corresponds to the end of the opening start phase or to the start of the closing end phase.

[0052] In other words, the blocking means 33 blocks, stops, halts, puts an end to the pivoting between the bent arm 31 of the double hinge and the body side 5 around the first axis 35 at the intermediate position of the rear door. It is the pivoting of the connecting rod 31 around its two axes 32, 35 which allows the rear door to pass from the closed position to the intermediate position. It results from these simultaneous pivotings around the two axes 32, 35 that the rear edge 22 of the rear door 20 shifts laterally outwards and then moves back slightly. This movement of shifting the rear edge 22 of the rear door is also simultaneous with the guidance of the means 25, 23 along the corresponding rails 51, 53.

[0053] Once the locking means 33 has stopped the pivoting about the first axis 35, the connecting rod 31 of the double hinge 30 can then only pivot about the second axis 32. In other words, a pivoting about the second axis 32 between the connecting rod 31 and the rear edge 22 of the rear door takes over to open the rear door 20 further. In particular, this pivoting makes it possible to move from the intermediate position of the rear door 20 (Figures 5 and 8) to an opening position of the order of 90 degrees for example (Figures 6 and 9), or even beyond, for example an opening of the rear door 20 of the order of 170 degrees (Figures 3, 10 and 12).

[0054] Thanks to the locking means 33, pivoting between the connecting rod 31 and the body side 5 is also prevented between an open position of the rear door, for example a fully or substantially fully open position of the rear door 20 (figures 3 in particular), and the intermediate position ([Fig.5] in particular) of the rear door 20 during closing of the rear door.

[0055] For example, as illustrated in [Fig.l 1], the locking means 33 comprises at least one magnet 34. Preferably, the locking means 33 comprises a magnet 34 fixed to the link 31. Preferably, the locking means 33 comprises another magnet 34 fixed to an inner face 7 of the body side 5. Advantageously, the magnet 34 fixed to the link 31 and the magnet 34 fixed to the inner face 7 of the body side are intended to be opposite each other, preferably to be in contact with each other during the intermediate opening position of the rear door. The faces of the magnets 34 facing each other in the intermediate position of the door 20 preferably have opposite poles so as to attract each other. Alternatively, another locking means may be suitable, possibly at the level of each double hinge 30.

[0056] As illustrated in particular in Figures 7 to 10, the vehicle comprises a front seat belt 60 for the occupant of the front seat 4, in particular for a front passenger. More specifically, as illustrated in [Fig. 10], the front door 10 comprises fixing means 65 for the front seat belt 60. The belt 60 comprises for example a first end 61 and a second end 62. The vehicle also comprises a reel 64 for the belt 60. Preferably, it is the front door which comprises the supports or fixings 65 for the ends 61, 62 of the belt 60 and / or for the reel 64 of the front seat belt 60. A return 63 for the seat belt 60 is preferably fixed on the front door, between a window 27 and the rear edge 12 of the front door 10.

[0057] Advantageously, as illustrated in Figures 3, 6, 9, 10 and 12, two double hinges are provided. Preferably, they are arranged substantially one above the other, their first axes and their respective second axes being coaxial or substantially coaxial. For example, the hinges 30 are arranged in the vertical direction substantially at the middle of the rear edge of the rear door, or even at the first lower half of the rear edge of the rear door.

[0058] As illustrated in [Fig.12], the rear door 20 preferably comprises a lock 28 and the body side 5 preferably comprises a corresponding striker 58.

[0059] Optionally, as illustrated in [Fig. 12], on one of the two double hinges, for example the lower one, a door stop 26, for example notched, is provided to prevent the rear door from opening and / or closing too violently following a gust of wind for example. Such a stop or pivot limiter 26, for example comprising notches and an elastic means such as a spring, is preferably arranged at the level of the second axis, for example around the second axis, so as to limit the pivoting around this second axis between the connecting rod and the rear edge 22 of the rear door 20. This pivoting limiter, with several opening notches for example, guarantees the braking of the rear door also when the vehicle is in an angular position favoring its untimely opening and / or closing, in particular when the lock / strike pair 28, 58 is not locked.

[0060] Thus, the method of opening the rear door 20 begins with a first phase comprising the translation of the front edge 21 along the rails 51, 53 simultaneously with the pivoting around the axes 32, 35 of each link 31 of the double hinges 30. This first phase ends with the locking of the pivoting around the axis 35 by the locking means. This first phase results in a lateral shift towards the outside of the vehicle of the rear door 20 as well as a recoil of the rear door 20. Following this first phase, the rear door 20 is therefore laterally shifted from the body side 5 and moved back slightly as illustrated in [Fig.5]. As a result, the front edge 21 is free since it is no longer held by the rails 51, 53.

[0061] The method of opening the rear door 20 then comprises a second phase comprising pivoting about the axis 32 of each double hinge. This second phase causes pivoting substantially about the rear edge 22 of the rear door 20. For example, this pivoting can be done up to an opening angle of the door of approximately 90 degrees illustrated in [Fig. 6], or even up to an angle of approximately 170 degrees illustrated in [Fig. 3].

[0062] The method of closing the rear door 20 begins with a pivoting phase around the axis 32 of each double hinge. This phase causes the pivoting substantially around the rear edge 22 of the rear door 20, for example from an opening angle of the door of approximately 90 degrees illustrated in [Fig. 6], or even from an angle of approximately 170 degrees illustrated in [Fig. 3].

[0063] Following the pivoting around the axis 32, when the front edge 21 of the rear door is close to the slides 51, 53 (figures 13 and 15), the rolling and / or sliding means 23, 25 are engaged, inserted, and made to cooperate with the corresponding rails. Once the means 23, 25 are guided in the rails 51, 53, the manipulation of the door 20 towards its complete closure causes a release of the locking means 33, 34. This results in simultaneous pivoting around the axes 32, 35 of each connecting rod 31, which contributes to shifting the rear edge 22 of the door 20 towards the interior of the vehicle simultaneously with the translation of the front edge 21 guided by the rails 51, 53, to the complete closure position illustrated in [Fig.2] in particular.

[0064] In summary, the solution relates to the arrangement 2 comprising the body side 5 equipped with the front hinged door 10 around the front axis 15 and the rear door 20 cou smooth-swinging, the body side not including a center pillar. As a result, the lateral opening 6 allowing access to the passenger compartment when the two doors 10, 20 are open is maximized. Indeed, when the front and rear doors 10, 20 are fully open ([Fig.3]), the doors do not in any way obstruct access to the passenger compartment.

[0065] As seen previously, when the rear door 20 is opened, it begins by sliding at its front edge 21. This sliding is ensured by the presence of the lower and upper rails 51, 53 arranged within the body side 5 cooperating with the rolling and / or sliding means 23, 25 fixed to the rear door 20. This sliding occurs simultaneously with pivoting of the double hinge(s) 30 around their two axes. Thanks to this combination of movements, the front edge 21 of the rear door begins by moving back while moving laterally away from the rear edge of the front door (in the closed position of the front door). The pivoting around the second axis 35 ends when the locking means 33 is activated, for example when two magnets 34 touch or stick together. This locking position corresponds to the rear door in the intermediate position illustrated in figures 5 and 8.Note that in this intermediate position and therefore blocking of the pivoting around the second axis 35, the means 23, 25 are completely removed from the rails 51, 53 and the main and secondary blocking means 40, 45; 42, 47 no longer cooperate. Thus, the front edge 21 of the rear door 20 is free. Then, to continue opening the rear door beyond the intermediate position, the pivoting around the second axis 32 occurs. This pivoting is done between the arm 31 and the rear edge 22 of the rear door 20. The rear door can then be opened, which then resembles a swing door up to an opening of the order of 90 degrees (figures 6 and 9), or even beyond, for example up to approximately 170 degrees (figures 3 and 10).

[0066] Preferably, the front door 10 is fixed to the body 3 by two usual hinges in the front zone, with a front axis 15, that is to say at the level of the front edge 11. The front door 10 preferably comprises two locks, an upper one and a lower one in the rear part of the door, that is to say at the level of the rear edge 12 of the front door 10. As illustrated in [Fig. 3], preferably, a striker 59 is provided on the upper part 50 of the body side and a striker 59 is provided on the lower part 52 of the body side to cooperate with the two locks. Advantageously, the sealing at the level of the body is achieved by a usual seal provided on the body.

[0067] Preferably, as illustrated in [Fig.3], the rear door 20 supports, includes a vertical seal 29 at its front edge 21. The vertical seal 29 is adapted to compress on the rear edge 12 of the front door 10 when closing the rear door 20 while simultaneously crushing a main body seal. The seal 29 of the rear door 20 is positioned, arranged, so as to be preferably stressed in compression when closing the front door 10 on the already closed rear door 20. Preferably, a single seal 29 is provided to ensure sealing between the rear edge 12 of the front door 10 and the front edge 21 of the rear door 20.

[0068] As seen previously, the rear door 20 is carried by two double hinges 30 each having two axes of rotation or pivoting 35, 32 in the rear part or zone, and by two guide carriages 25, 23 for the start and end of travel in the front part. The two carriages 25, 23 are housed in the two guide rails 51, 53 of short length arranged at the top of the body 50 and at the bottom of the body 52 so as to impose the trajectory of the start of opening and the end of closing of the front of the rear door during handling.

[0069] Note that during the entry / exit path of the rear door 20 in the rails 51, 53, the hinges pivot on their two axes of rotation until the locking mechanism 33 locks one of the pivots of the double hinges to leave the other pivot free. Once one of the two pivots is locked, the rear door can pivot in the manner of a conventional swing door. The rear door then pivots around an axis arranged at the rear of the rear door.

[0070] As mentioned previously, the first part of the trajectory during opening is a translation along the rails of the front edge 21 of the door 20 simultaneously with pivoting around the axes 32, 35 causing a lateral shift of the rear edge of the door 20. This is followed by the blocking of the pivoting around the axis 35 by the means 33 which causes, while continuing the opening manipulation, the simple rotation around the external axis 32 of the double hinges in the manner of a conventional swing door.

[0071] As a reminder, the lock 28 is fixed to the rear door 20 in its rear area, at the rear edge 22, and allows, with the latch 58, to keep the door closed. The carriages 23, 25 are then held in the rails 53, 51 in the front part with the help of the centering device or cylindrical finger 43 fixed in the lower part of the door and cooperating with the bore 48 and with the help of the holding fork 41 in the upper part at the level of the upper rail 51 and cooperating with the finger 46.

[0072] Advantageously, the lower carriage 23 and the upper roller 54 guide the rear door 20 only during the travel of the movements of the rear door for which the two axes of the double hinges 30 are free to pivot.

[0073] Thanks to the solution, a van-type vehicle of modest size can easily have at least one front passenger seat rotating around 180 degrees around a vertical axis to find itself facing backwards. Such a seat position is particularly advantageous in the case of a table or tablet arranged behind the front row of seats, for example for having a meal. In addition, the interior of the vehicle can easily be transformed into a mini lounge, possibly equipped with a rear bench seat. that can be transformed into a double bed on the rear part of the vehicle. Indeed, these transformations are made possible thanks to the opening 6 on the body side 5 optimized to be very wide. This significant width is obtained by the absence of a center pillar and by the side doors 10, 20 which offer maximum access 6 and facilitate modularity within the passenger compartment. The solution greatly facilitates the use of booster seats on the seats to install children, both as front and rear passengers.

[0074] Note that the front door 10 integrates the functions of the absent center pillar, in particular by supporting the front seat belt 60 and the various related anchor points. The solution makes it possible to open then close, or close then open, the rear door 20 while the front door 10 is closed (Figures 4 to 6). However, the solution also makes it possible to open then close, or close then open, the front door 10 while the rear door 20 is closed. In addition, the kinematics of the doors 10, 20 make it possible to open both doors simultaneously and / or to close them simultaneously. The various seals for sealing are compatible with these movements. Thus, a rear passenger can exit, or can enter, through the rear door without having to open the adjacent front door. In addition, the rear passenger is not hindered by the front seat belt 60 since it does not extend behind the front door, even when not in use.If the front seat belt 60 is fastened by a front passenger, the latter can keep it locked when a passenger behind him gets in or out. The fastened seat belt 60 does not hinder the comings and goings of a rear passenger. Since there is no order for the openings / closings of the adjacent front and rear doors, access to and exits from the vehicle are facilitated, which is a guarantee of rapid evacuation of the vehicle in the event of an accident if necessary and helps to reassure users.

[0075] The solution still makes it possible to exit the vehicle even if it is parked in the immediate vicinity of a post or a wall or another obstacle, the kinematics of the doors easily providing an exit, in particular because the doors are independent.

[0076] Note that the shape of the arm 31, provided in particular with the first and second portions 38, 39, is defined to ensure optimal kinematics of the rear door.

[0077] Thanks to the solution, in particular in the case of a van-type motor vehicle comprising a body side with wide access to the vehicle without a B-pillar, it becomes possible to have hinged front and rear doors, pivoting around vertical axes without inconvenience. In particular, the rear door can be hinged around axes at the rear edge of the rear door and the front door can be hinged around an axis arranged at the front edge of the front door. In other words, although the doors are hinged and there is no B-pillar, no order of opening and / or closing is to be respected. The front door can be open and can be closed independently of the rear door, i.e. rear door open, closed or still in the process of opening or closing. In the same way, the rear door can be opened and can be closed independently of the front door, i.e. front door open, closed or still in the process of opening or closing. Thus, a rear passenger can exit the vehicle, or enter the vehicle, by opening the rear door without having to operate the front door, in particular without asking another passenger for help to operate the front door. This results in simplicity for access to the vehicle and for exiting the vehicle, which also becomes an asset in terms of safety, following an accident damaging the front door for example.

[0078] As a reminder, the front belt is fully fixed to, supported by, the front door, in particular at the rear inner edge of the front door. Thus, the front seat belt does not hinder exit or access via the opening provided by the adjacent rear door in the open position.

[0079] As a remark, the solution therefore achieves the desired objective of allowing a body side without a B-pillar offering access within a maximized passenger compartment to be compatible with swing doors that are totally independent in terms of opening and / or closing while avoiding the front beltline hindering access at the rear door and has the advantages of being able to be used on other types of vehicles requiring a large opening, namely utility vehicles, or even trucks.
