Definitions

• the present invention relates to a vehicle door opening as close as possible to the body of said vehicle, means being associated to effect its opening, closing and locking automatically and/or manually.
• Said door is also equipped with a movable window that can detach from said bodywork and translate along said door.
• Automobile doors are mostly made in a single block pivoting around a vertical axis. Therefore, when they are open, they significantly increase the width of the vehicle, and require space on the side of the vehicle. Closing is entirely manual and requires the door to be “slammed", which generates an overpressure in the passenger compartment, requiring the implementation of valves letting the air escape. In some cases, they have a motorized latch blocking a bolt placed on the opening of the bodywork, which requires bringing electricity inside the door. In addition, the movable windows are placed in the upper part of the door and fit inside the lower part when opening. This requires having windows with a ruled surface and doors that remain in one rigid piece.
• An object of the invention is first of all to improve the known products and systems.
• the present invention makes it possible to overcome all the drawbacks mentioned above. It makes it possible in particular, but not exclusively, to produce for a bodywork having surfaces with complex geometry (such as for example surfaces with spherical, toroidal, hybrid or other components, or surfaces with large radii of curvature.) a vehicle door having simple kinematics, which can be adapted to any bodywork design, opening as much as possible close to the bodywork, closing without creating excess pressure, managing closing and locking without electricity supply in the door, and allowing to have a mobile window opening widely whatever its geometry and the shape of the bodywork .
• a door according to the invention is therefore on the one hand simple to produce and on the other hand very light.
• This door can thus be installed on a one-piece bodywork or made in several parts.
• This bodywork may have two small openings on one side (for example one to access the front seats and one to access the rear seats), or a single large opening allowing access to all the seats (front and rear) and offering a very great accessibility.
• the body can thus be fitted with one or two doors per side, or even more (for example one per row of seats).
• the principle of the door according to the present invention is not limited to use on a side door but can be applied to a trunk door for example.
• the door is sectional, ie it is made up of two kinematic groups.
• the first group is the upper frame which pivots around an upper axis whose orientation is substantially longitudinal (in the longitudinal direction illustrated in FIG. 1a) placed on the roof of the bodywork.
• the second group is the lower leaf which pivots around a lower axis whose orientation is also substantially longitudinal and placed on the upper frame.
• the height of the lower leaf is lower than the height of the upper frame. Therefore, the lower leaf does not obstruct the opening and does not interfere with entering or exiting the vehicle.
• the door preferably has three distinct positions: an open position, a semi-closed position, and a closed position.
• the open position the door does not cover the opening in the body, allowing users to enter or exit the vehicle.
• the semi-closed position the opening of the bodywork is obstructed by the door, but sealing is not yet achieved between the inside and the outside of the passenger compartment of the vehicle.
• the closed position sealing is achieved between the inside and the outside, and the door is ready to be locked in position.
• the upper frame preferably pivots only a few degrees.
• the door is provided with at least one bolt and at least one detectable element, preferably two of each, one at the front and the other at the rear of the door.
• a sensor is installed in the body.
• a cam striker is installed in the body.
• the bolt is guided in a groove of the cam striker.
• this groove is substantially wider than the bolt, so that the bolt can enter it even when the latter has a positioning fault.
• the cam has geometries allowing it to be able to pull on the bolt even if the latter is not perfectly positioned.
• the door has a locking system to prevent it from being opened from the outside.
• the motor or the transmission rotating the cam have a non-reversible movement.
• the door is, in fact, locked in this closed position.
• the locking of the door is achieved by the entry of the bolt into a fixed cavity of the cam striker. Unlocking is in this case carried out by a second cam pushing the bolt out of this cavity.
• the lower leaf In the closed position, the lower leaf is blocked on a geometry of the bodywork (for example by a leaf-bodywork interlocking), creating a fourth anchor point for the door, in addition to the pivot on the roof, and the two blocked bolts in the cam strikers.
• These four anchoring points prevent the door from being torn off (vandalism, car-jacking, theft) or from being pushed in (parking impact, side crash vandalism).
• the curvature of the door means that, in the event of depression, it braces against the edges of the opening, for a better hold in place.
• the cam pivots in the opposite direction to that of closing, thus pushing the bolt out of the cam striker, and thus the door to the semi-closed position.
• This action can also be performed manually by acting on a handle, for example, which will pull on the bolts to make them come out of the cam striker. In this case, it is the elasticity of the door seals that will push the door to its semi-closed position.
• cylinders mounted between the bodywork and the door (or other equivalent means) will push the door to its open position, without the need for manual action on the part of the user.
• the cam striker When the sensors no longer detect the presence of the detectable elements of the door, the cam striker returns the cam to a position where it is ready to close again, if it is not already in this position (for example if the passage to the semi-closed position closed was done manually).
• unlocking is done simply by pivoting the cam in the opposite direction to that of closing.
• a handle or a button can also be installed in the passenger compartment of the vehicle, the manual pulling of this handle or the pressing of this button uncoupling the closing motor and the cam. In this configuration, nothing blocks the opening of the door.
• the elasticity of the seals and/or a manual action on the door makes it possible to push it from the closed position to the semi-closed position, the bolt pushing the cam into its open position, said cam no longer being locked in rotation by the non-reversing engine or transmission.
• the only electrified elements are the motor and the sensor. These elements are fixed to the bodywork. Thus, no element requiring electricity is present in the door, making it possible to avoid both additional costs, significant masses and breakdowns.
• Operation of the door opening-closing system can be manual, partially or totally assisted (for example with jacks, springs, etc.), partially automated or fully automated, the user simply giving a command (by example by pressing a button or other equivalent such as manipulation of a handle of the door) for part of the door movement or for the entire movement (opening and/or closing).
• the command can also be linked to the status of the vehicle (stopped in the “parking” position, or switched on for a departure) and/or customizable with respect to said status.
• the command can also be given by a remote control, such as the car key, or by specific sensors, for example the detection of the physical position of the user (RFID etc.).
• the movable window of the door therefore opens by unsticking slightly outwards (semi-closed or semi-open position), then by translating backwards (open position).
• the system is provided with two rails: a fixed rail mounted on the door, and a mobile rail mounted on the mobile window.
• a fixed rail mounted on the door is positioned on the upper frame of the door.
• the fixed rail is positioned on a fixed window.
• a roller is guided in translation in each rail, and this roller is connected to the rest of the system by a connecting rod allowing the window to be lifted from its closed position to its semi-closed position.
• Stops are implemented to block the translation of the rollers in the closed position, to limit the separation of the window, and to block the movement of the connecting rods between the semi-closed position and the open position.
• a locking system is also installed on the mobile window to prevent it from being opened from outside the vehicle. Detachment only from the rear of the window is possible to allow a stream of air to pass at the rear of the passenger compartment.

• Said opening (12) can give access only to the front seats (16) or only to the rear seats (17).
• Said body (11) may also have two openings (12), one giving access only to said front seats (16) and the other giving access only to said rear seats (17).

• Said door (20) mainly comprises an upper frame (21) pivoting around an upper pivot (23) placed on the roof (13) of said bodywork (11), and a lower leaf (22) pivoting around a pivot bottom (24) placed on said top frame (21).
• Said door (20) is described as sectional.
• the axes of said upper pivot (23) and lower pivot (24) are substantially longitudinal.
• said bodywork (11) and said lower leaf (22) are made of the same material so that thermal expansion does not disturb the operation of said door (20), and in order to have an identical color and surface condition.
• Said upper frame (21) can also be made of the same material, although this is less critical for the operation of said door (20).
• said upper frame (21) or said lower leaf (22), or both elements are made of synthetic material or fibers, which avoids damaging the external elements that they could touch, for example the sheet metal bodies of surrounding vehicles.
• said upper pivot (23) is significantly farther transversely than vertically from said lower pivot (24).
• the opening or closing of said door (20) is therefore done along the shape of said bodywork (11), said leaf bottom (22) not deviating from said bodywork (11) but rising or falling, allowing said door (20) to have a movement exceeding by a minimum value, or even by a zero value, the overall width of said vehicle (10).
• said door (20) can open even when a person or an object, in particular another vehicle, or a wall is in front of or near said door (20), on the side of said vehicle ( 10).
• said lower leaf (22) has a height less than the height between said upper pivot (23) and said lower pivot (24).
• said door (20) opens when it detects the presence of an element identifying its owner, for example an RFID chip contained in a card or a key, and/or when a button exterior opening of said door (20) is pressed. Said button may be next to said door (20).

• the two parts forming said upper pivot (23) and lower pivot (24) are not far apart longitudinally in order to be able to perform their function even if said bodywork (11) has a surface with a complex geometry.
• a beating spring (26) is installed between said upper frame (21) and said lower leaf (22) in order to orient said lower leaf (22) towards the interior of said vehicle (10), independently of gravity.
• This spring can be, without limitation, a tension spring, compression spring, torsion spring or a torsion bar. Other equivalent means are of course possible to obtain the same effect.
• Said door (20) preferably has three distinct positions: an open position, a semi-closed position (or also called “semi-open"), and a closed position.
• said door (20) In the open position, said door (20) does not cover said opening (12) of said bodywork (11), which allows users to enter or exit said vehicle (10).
• said door (20) In the semi-closed position, said door (20) is in front of said opening (12), but sealing is not yet achieved between the inside and the outside of the passenger compartment of said vehicle (10).

• Said door (20) can also rest on the edges of said opening (12).
• said door (20) is provided with at least one bolt (40), and with at least one detectable element (25), preferably two of each, one at the front of said door (20) and the other at the rear of said door (20).
• a door sensor (37) is installed in said body (11).
• a cam striker (30) is installed in said bodywork (11).
• said door sensor (37) is installed directly on said cam striker (30).

• the invention is however not limited to these elements and can use other equivalent means.
• These elements represent security for users.
• the passage of said door (20) from the semi-closed position to the closed position is achieved by the actuation of mechanical elements that can injure the user.
• These elements can only be set in motion when said door sensors (37) detect the presence of said detectable elements (25). In this position, the mechanical elements will no longer be accessible to users, and their movement cannot therefore injure them.
• a gripping strap (27) can be installed on said lower leaf (22) so that the user can bring said door (20) into the semi-closed position, even when seated inside said vehicle.
• An armrest (22e) on said lower leaf (22) makes it possible to assist at the end of the movement, the user being able to simply press on this armrest.
• said armrest (22e) is not a separate part mounted on said lower leaf (22), but is a geometry making an integral part of said lower leaf (22) in order to be rigid and to avoid fixings which would represent a weak point (and to avoid loss of time for assembly operations).
• a frame handle (21a) is installed on said door (20) to have a grip zone which guides the hand out of said lower pivot (24) to prevent it from getting caught between said upper frame (21 ) and said lower leaf (22).
• a flap handle (22f) can also be installed, lower than said frame handle (21a), and thus more accessible for people of small stature. In another mode of execution, the movement is not performed manually but is assisted and/or performed automatically by appropriate means (motor, transmission, etc.).
• said bolt (40) In the semi-closed position, said bolt (40) is at the entrance to a guide groove (35) hollowed out in said cam striker (30), said door sensors (37) face said detectable elements (25) of the door (20) so as to be able to detect their presence.
• This detection triggers the rotation of a cam motor (33) which drives the rotation of a cam pin (34) on which is mounted a closing cam (31) in said cam striker (30).
• Said closure cam (31) has a closure cavity (31a). When said closure cam (31) rotates, said closure cavity (31a) is placed around said bolt (40) then drives it in its movement thus pulling on it and at the same time pulling said door (20) towards the interior of said vehicle (10), compressing said door seals (18) until reaching the closed position.
• the guide groove entrance (35a) of said guide groove (35) and said closing cavity (31a) have dimensions larger than the diameter of said bolt (40) so that said closing cavity (31a) can push said bolt (40) in said guide groove (35) even if said bolt (40) is initially incorrectly positioned.
• Said door (20) has a locking system to prevent its opening from the outside.
• said cam motor (33) or its transmission system pivoting said closing cam (31) has a non-reversible movement.
• Said door (20) is, in fact, locked in this closed position. This is the case, for example, if said closing cam (31) is fixed to a pinion driven in rotation by a worm having a low helix angle.

• said bolt is in front of a locking cavity (36) into which said bolt spring (42) pushes it.
• Said locking cavity (36) being fixed, the position of said bolt (40) and therefore of said door (20) is locked independently of the position of said closing cam (31) and therefore of said cam motor (33).
• a bolt sensor (38) can be installed in said locking cavity (36). When said bolt (40) enters said locking cavity (36), the latter is detected by said bolt sensor (38) thus confirming the locked state of said door (20).
• Said bolt sensor (38) may for example be a Hall effect sensor, an inductive sensor, an optical barrier, a mechanical switch, or an electrical switch. The invention is however not limited to these elements and can use other equivalent means.
• said leaf opening abutment (22b) and said leaf closing abutment (22c) are positioned on said leaf anchor (14).
• said lower leaf (22) cannot be pulled out or pushed in.
• said door (20) thus has four anchoring points preventing it from being opened: said upper pivot (23) locked in translation in said roof (13), said bolt (40) locked in translation inside said cavity of lock (36) at the front of said door (20), said bolt (40) locked in translation inside said locking cavity (36) at the rear of said door (20), and said lower leaf (22) blocked in translation by said swing anchor (14).
• said bolt (40) has a bolt shoulder (40a) resting on said closing cam (31) when said door (20) is in closed or locked position.
• the support between said closing cam 31 and said bolt shoulder (40a) prevents the axial translation of said bolt (40) so that said bolt (40) cannot slip out of said cam striker (30), even when said door (20) is forced and deformed towards the exterior of the vehicle.
• Said shoulder bolt (40a) thus improves the anchoring of said door (20) in said bodywork (11).
• an unlocking cam (32) is mounted on said axis cam (34).
• Said unlocking cam (32) is provided with an inclined unlocking plane (32a).
• said cam motor (33) rotates in the opposite direction to that of closing, said unlocking inclined plane (32a) pushes said bolt (40) out of said locking cavity (36), compressing said bolt spring ( 42).
• said cam motor (33) continues to rotate in the same direction and an opening cavity (31b) in said closing cam (31) pushes on said bolt (40) to come out of said guide groove (35). The door is then in a semi-closed position.
• This action can also be performed manually by actuating a handle (43) which, via a system of rods (44), will pull on said bolt (40), compressing said bolt spring (42). Said bolt (40) will thus come out of said cam striker (30). In this case, it is the elasticity of said door seals (18) which by decompressing will push said door (20) to its semi-closed position.
• unlocking takes place in the same movement as opening: said cam motor (33) pivots in the opposite direction to that of closing, and said opening cavity (31b) in said closing cam (31) pushes said bolt (40) out of said guide groove (35).
• the door then moves to a semi-closed position.
• This action can also be performed manually by activating a handle or a button which, via a transmission system (links, cables, motor or other), will uncouple said closing cam (31) from the non-reversible component said cam motor (33) or its transmission system.
• Said closing cam (31) being again free in rotation, said door seals (18) can be decompressed thanks to their elasticity and bring said door (20) to its semi-closed position.
• At least one or preferably two cylinders (15) mounted between said vehicle (10) and said door (20) will push said door (20) to its open position.
• Said cylinders (15) are mounted in such a way that in the closed position of the door they induce very little torque on said door (20), which makes it possible to place said door (20) in the semi-closed position manually without the need of great strength, and also makes it possible not to force the closing and locking elements described above.

• said cylinder (15) can be equipped with a damping system slowing down the opening movement of said door (20) when approaching the open position.
• a spring for compensating the mass of said door (20) can also be installed around said upper pivot (23), the latter being compressed when said door (20) is closed, then assisting said cylinders (15) to take off said door (20) of said body (11) by a few degrees when said door (20) is in the semi-closed position and said cylinders (15) have a force relatively equivalent to that necessary to open said door (20).
• This action zone is represented by way of example in figure 12.
• said compensation spring will apply a force to said door (20) when said door (20) has an opening angle of between three and five degrees, which will make it possible to have a more frank opening of said door (20), to have a cam striker (30) opening said door (20) only up to three degrees instead of four degrees , to compensate for the friction and wear of the system, and/or to compensate for the climatic conditions, said cylinders (15) being able for example to have lower forces when the temperature of use is low.

• Said movable roller (54) is in sliding connection with said fixed rail (51).
• a window locking system (57) blocks the detachment of said mobile window (50).
• said window locking system (57) is a three-point toggle system manipulated by the user and accessible only from inside the passenger compartment of said vehicle (10) in order to prevent the opening from the outside and avoid intrusions.
• Other equivalent systems are of course possible.
• a fixed slide stop (51a) and a movable slide stop (52a) prevent the translation of said movable window (50) towards the back.
• a fixed opening stopper (53a) a movable opening stopper (54a) block the rotation of said fixed rod (55) and of said movable rod (56), limiting the detachment of said movable window (50).
• a fixed closing stop (51b) and a movable closing stop (52b) prevent said movable window (50) from sticking back transversely towards the interior of the passenger compartment of said vehicle (10) .
• Said fixed opening stopper (53a), movable opening stopper (54a), fixed closing stopper (51b) and movable closing stopper (52b) therefore prevent movement and excessive vibration of said movable window (50) when the latter is open. and that said vehicle (10) is moving.
• an opening slope (59) can be positioned at the end of said fixed rail (51) and of said movable rail (52) in order to open said movable window (50) in one single longitudinal movement: said fixed slide stop (51a) and mobile slide stop (52a) have a low height and are followed by said opening slopes (59).
• said window locking system is unlocked, the elasticity of said window seal (58) pushes said movable window (50) in transverse translation outwards.
• the closing stops (51b and 52b) are found opposite said opening slopes (59).
• a longitudinal thrust on said movable window (50) will bring said closing stops (51b and 52b) into contact with said slopes (59), forcing said closing stops (51b and 52b) to translate transversely in order to effect the large longitudinal opening.
• the translation transverse and longitudinal translation are done in a single movement, facilitating handling for the user.
• closing springs (60) can be installed between the fixed and movable parts of said movable window (20).
• This can for example be a torsion spring resting on said fixed rail (51) and on said fixed link (55) and another torsion spring resting on said movable rail (52) and on said movable link
• a hook (61) can be implemented on said fixed rod (55), said movable rail (52) or an element of the same kinematic group as said movable rail (52) being housed therein when said movable window (50) is in the closed position .
• Said hook (61) thus makes it possible to block the rotation of said fixed rod (55) and the translation of said movable rail (52) when said movable window (50) is in the closed position.
• Said hook represents a second locking point of said movable window (50) in the closed position, in addition to said window locking system (57).
• the invention is however not limited to these elements and can use other equivalent means.
• Said movable rail (52) exits from said hook (61) by a slight transverse movement of said movable rail (52) performed during passage of said movable window (50) from the closed position and the semi-closed position.
• This movement can be performed manually by the user.
• the interface between said movable link (56) and said fixed slide stop (51a) has an inclined plane.
• said slight transverse movement to release said hook (61) from said fixed rod (55) is imposed by said inclined plane, said mobile link (56) having to follow the geometries of said fixed slide stop (51a) in order to free itself therefrom.
• a tab (62) mounted on a tab spring (63) can be implemented between said hook and said movable rail (52) in order to reduce and assist the slight transverse movement, while maintaining good locking in position. closed.
• the kinematics as described allows the person on said rear seat (17) to half-open said movable window (50) by taking off only the rear. It can be reattached from said rear seat (17) or from said front seat (16). This kinematics only works if the person on said front seat (16) unlocks said window locking system (57).
• This mobile window system does not require electricity.
• the fact of eliminating the electric motor allows at the same time a lightening, a lower cost and the saving of rare earths, therefore an ecological footprint lesser.
• Said door (20) is therefore entirely non-electrified and of simple construction.
• assistance means can be provided which partially or totally automate the opening and closing of the window, the user merely placing the order (for example by pressing a button).
• the invention also relates to a vehicle comprising the elements described above alone or in combination, namely at least such a door and/or such a cam striker system and/or such a window.
