Description

Method for manufacturing a door of a motor vehicle,

  corresponding door and vehicle.

  The field of the invention is that of the bays made in the vehicle doors. More specifically, the invention relates to a method of manufacturing a door of a motor vehicle and comprising a part movable in an essentially vertical direction, capable of closing or freeing an opening. The invention applies in particular, but not exclusively to the side doors of motor vehicles, and can also be applied to

rear doors.

  Conventionally, the manufacture of a vehicle door includes the production, generally by stamping, of a monobloc assembly composed of a lower part forming the box of the door and an upper part

  constituted by a frame delimiting a bay.

  A shutter device for the opening, comprising a glazed panel, is then mounted on the monobloc assembly, as well as the various members necessary for the proper functioning of the shutter device, and in particular: - the means for guiding the glazed panel; - the means for driving a glass panel; - the seal (s); optionally, the motorization means of the device; Such a manufacturing process therefore involves a long and tedious assembly range at the level of motor vehicle manufacturers, adjustments of the shutter device being most often necessary after the

  mounting it in the door.

  At the same time, a technique has been proposed by the Holder of this patent application. This technique is notably described in the documents of

  Patent EP-0 778 168 and EP - 0 857 844.

  Thanks to this technique, one obtains "flush berries" which present, on the aesthetic level, seen from the outside, a smooth appearance, flush with the fact that none

frame is not necessary.

  According to the prior art proposed by the Holder of this patent application, the "flush bays" comprise a fixed assembly and a mobile part, the fixed assembly being intended to be mounted in the defined housing

  for this purpose on the vehicle body.

  However, the openings in the doors have relatively limited dimensions which it is therefore not advisable to reduce further by bringing a

  fixed assembly according to the prior art.

  However, it is desirable to be able to equip certain vehicles, in particular luxurious vehicles such as minivans, with flush-fitting bays,

  the front flush windows are not suitable for the doors of these vehicles.

  The present invention provides a solution for quickly and simply manufacturing a vehicle door, including when planning

  to equip the door with a flush opening.

  More specifically, the invention aims to provide a method of manufacturing a door of a motor vehicle which allows to consider

  notable simplifications in terms of manufacturing and assembly logistics.

  Another object of the invention is to provide such a manufacturing method which makes it possible to produce doors having characteristics

  news, especially with regard to aesthetics and ergonomics.

  These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to a method for manufacturing a door of a motor vehicle, characterized in that it comprises the following stages: '' a lower door box; manufacturing an upper door assembly, comprising at least one movable glass panel, capable of sliding at least partially inside said box between a closed position and at least one open position, said upper assembly comprising at least a guide and / or fixing amount; - assembly and securing of said lower box and said assembly

  upper, using said one or more guide and / or fixing posts.

  In this way, the different means constituting the upper assembly can be assembled and pre-adjusted before being secured to the door casing. The assembly of the upper assembly on the box is simple; the method of manufacturing a door according to the invention therefore allows the motor vehicle manufacturer to envisage significant time savings, the latter having only to produce the box and its assembly with

  a pre-set, ready to use.

  Preferably, said step of manufacturing said upper assembly comprises a step of shaping at least one of said uprights so as to provide thereon means for guiding, positioning and / or holding

  of said one or more uprights in said box.

  According to an advantageous solution, said step of manufacturing said upper assembly comprises a step of mounting, on said or said uprights, a seal against which the face of said movable glazed panel facing the interior of the vehicle comes to rest in said closed position, and a step of mounting means for slightly moving said movable glass panel and said seal from one another, in a sliding position in which said movable panel can slide without damaging said seal sealing, and to bring back said movable glass panel and said seal

  sealing pressing one against the other, in said closed position.

  In this way, the device is sealed when the mobile panel is in the closed position, while avoiding, or at least limiting, the harmful or undesirable effects due to the interaction between the

  movable panel and seal.

  Indeed, by moving the movable panel away from the joint while the panel slides vertically, one avoids: - premature wear of the seal likely to be caused by successive friction of the panel against the joint; noises (such as screeching), again due to the friction of the panel against the joint, such noises being able to increase with the structural modifications of the joint due to temperature variations,

  humidity or due to the sun's radiation, wear ...

  According to a first embodiment, said step of manufacturing said upper assembly comprises a step of mounting, on said post or posts, guide means allowing said sliding, and offset means, ensuring the distance between said movable glass panel and said seal. In this case, said step of manufacturing said guide means and said shifting means advantageously comprises the steps of: - mounting a guide rail on said post (s); - Securing said movable panel with at least one shoe whose movement is guided by said rail; - mounting of at least one ramp in said guide rail, ensuring a progressive shift of said movable panel relative to

audit seal.

  According to a second embodiment, the manufacturing process comprises

  a step of mounting inflation / deflation means of said seal.

  According to a third embodiment, the manufacturing method comprises a step of mounting a support for said seal, said support being mounted mobile.

  pivotally on said one or more uprights.

  According to any one of the embodiments which have just been described, the manufacturing process advantageously comprises a step of mounting means for driving said movable panel, ensuring said sliding. In this case, said step of mounting said drive means

  preferably comprises the mounting of motorization means.

  According to a first variant, said step of mounting said means

  drive includes mounting a single rail inside said box.

  According to a second variant, said drive means are mounted

  in at least one of said uprights in order to act on said one or more pads.

  The invention also relates to a motor vehicle door,

  mounted according to a method as described above.

  The invention also relates to a vehicle comprising at least one door

  mounted according to a method as described above.

  The invention also relates to an upper assembly for implementing a method of manufacturing a door as described above, characterized in that it comprises at least one movable glass panel, capable of sliding at least partially at the inside said box between a closed position and at least one open position, said upper assembly comprising at least one guide and / or fixing upright intended to penetrate

said box.

  Other characteristics and advantages of the invention will appear more

  clearly on reading the following description of an embodiment

  preferred of the invention, given by way of illustrative and nonlimiting example, and of the appended drawings among which: FIG. 1 illustrates the essential steps of the method of manufacturing a door according to the invention; - Figure 2 is an exploded view of an upper door assembly intended to be mounted on a door casing according to the manufacturing method according to the invention; - Figure 3 is a detailed view of the guide means of a shutter device intended to be attached to a door mounted along the

  manufacturing process according to the invention.

  The essential steps of the method according to the invention are illustrated by FIG. 1 which indicates: - a step 1, according to which a door casing 6 is manufactured, such a casing conventionally comprising an external panel, a lining, various reinforcing means, opening / closing systems; a step 2, according to which an upper door assembly 7 is produced, such an assembly comprising a frame 3 of which at least one of the uprights 31 comprises means for guiding a movable panel 1, these uprights 31 being intended to penetrate the box 6 and to be fixed therein; a step 3 consisting in making the uprights 31 of the upper assembly 7 penetrate into the box 6 and in assembling by any suitable means (by screwing, welding ...) the uprights 31 to

inside the box.

  It is understood that the order of steps 1 and 2 is provided for information, these

  two stages being, in practice, carried out in parallel.

  According to the subject of the invention, the frame 3 is attached and fixed to a box

  side door of a vehicle, as shown in Figure 3.

  It should be noted that, according to the present embodiment, the frame 3 is designed to support a fixed quarter window pane, independently of the shutter device according to the invention. This window 4 and, therefore, the part of the frame

  corresponding are therefore entirely optional.

  Referring to Figure 2, an upper assembly 7, according to the present embodiment of the invention, is obtained by assembling the following constituent elements: - a movable panel 1 in an essentially vertical direction along a rail central 22, driven between a closed position and an open position using motorized drive means (of the push-pull cable type for example) comprising a geared motor 21; - guide means (explained in more detail below) provided in the uprights of frame 3 and intended to cooperate with skids

  sliding 11 carried by the movable panel 1.

  According to a characteristic of the invention, provision is made for mounting a seal 5 on the frame 3, the seal 5 extending over the entire length of the

  visible part of the frame once assembled with the door casing.

  Thus, in the closed position, the movable panel 1 comes to bear against this seal 5 by crushing it slightly to ensure closure.

  hermetic of the device with respect in particular to humidity and drafts.

  As illustrated in Figure 3, the pads 11 carried by the movable panel 1

  are intended to slide on rails 31 formed on the uprights of the frame 3.

  According to the invention, provision is made for mounting, on the assembly 7, means making it possible to slightly move the movable glass panel 1 and the seal 5 from one another, in a sliding position in which the movable panel 1 can slide without damaging the seal 5, and to bring the movable glass panel 1 and the seal 5 in abutment one against the other

  the other, in the closed position.

  According to the present embodiment, these means consist of swaying ramps 32, 33 of the locking / unlocking movement and

  intended to cooperate with the pads 11.

  It is noted that provision is made for mounting, in the vicinity of each of the vertical edges of the movable panel 1, of two pads 11, one in the vicinity of the upper edge, the other in the vicinity of the lower edge. In parallel, two pairs of ramps 32, 33 are provided on each upright of the frame 3, one pair in the vicinity of the upper end of the corresponding upright, the other in the vicinity of its

lower end.

  Thus, during a downward movement (initialized from a closed position) of the movable panel 1, the lower edge of the pads 11 comes to slide on the upper edge of the swaying ramp 33, which causes an offset of the movable panel in the direction indicated by the arrow F2 on the

figure 2.

  The movable panel can then be lowered to a position

defined by a stop.

  Conversely, during an upward movement of the movable panel 1 (the upper edge of the latter arriving near the upper edge of the frame 3), the upper edge of the skids ll comes to slide on the lower edge of the weaving ramps 32, which causes the movable panel to move in the

  direction indicated by arrow Fl.

  The upper position of the movable panel is also defined by a mechanical stop. Note that the movement in the direction indicated by the arrow F1 is provided so that the movable panel 1 comes to bear on the seal 5 to ensure with it a tight closure, the movement in the direction indicated by the arrow F2 being meanwhile planned to spread the

  joint panel, to a position in which they are no longer in contact.

  It is also noted that the presence of the pairs of pads as indicated above and the corresponding guide means, at the top and at the bottom of the uprights of the frame, ensure a locking / unlocking movement of the movable panel according to which the latter remains permanently substantially parallel

to himself.

  Furthermore, according to the present embodiment, the movable panel is a tinted window making it possible to hide, in the closed position, the frame 3 and the

seal 5.

  The manufacture of the assembly 7 may further include a step of mounting motor means. These motorization means can be

  of the type described above (central rail).

  According to another conceivable embodiment, the assembly 7 can be equipped with motorization means also composed of a gear motor and a push-pull cable drive system, the drive system being connected to the pads carried by the panel. In this case, the drive means

  extend into the uprights of the frame.

  This second embodiment therefore makes it possible to eliminate the central rail 22, the mounting of the assembly 7 on the box then being easier than in the case of the first embodiment. The assembly 7 being pre-assembled, the manufacture of a door is obtained quickly and simply by inserting the assembly 7 in the box 6, between the outer panel and the lining of the latter, and by joining the two

  elements by any appropriate means.

  It is noted that according to another approach of the invention, the door can be provided so that the movable panel slides essentially in a single plane, while the joint is movable relative to the sliding plane of the panel. A first embodiment then consists in providing for the mounting of a seal capable of being deflated in order to reduce its section and to move it away from the plane of sliding of the panel, this prior to the sliding of the panel from its position d shutter. When returning to the closed position of the panel, the seal is re-inflated so as to bear against the

  panel and seal the assembly.

  According to another conceivable embodiment, the seal is mounted on a support mounted to move pivotally relative to the uprights, the support being pivoted towards the interior of the vehicle prior to the sliding of the panel from its closed position, then pivoted towards the panel when it is back in the closed position to bring the seal back against the

sign.
