  OPENING OF FRONT OR REAR DOOR OF MOTOR VEHICLE

  The invention relates to a door opening front or rear of

motor vehicle.

  Generally speaking, a front or rear door opening of a motor vehicle comprises an inner structure and an outer structure which are assembled together. These structures are generally manufactured from two soles, most often stamped and assembled against each other by welding, these two soles being respectively denominated in the current technical language "inner skin" and "outer skin". A door leaf thus manufactured serves as a support for the assembly of a large number of elements such as vibes (fixed eVou sliding), the system window-winder, hinges, locks, seals, ..., knowing that one generally distinguishes the door box

  in the lower part, and the door frame at the top, which is the glazed part.

  Such door opening of traditional design, however, has drawbacks among which can be cited in particular: an impossibility of achieving a perfect outcropping between the glazed portion and the door frame, the width of the door frame amounts represents a

  embarrassment for the vision of the occupants of the vehicle, in particular the driver.

  Furthermore, the glazed part of a traditional door opening generally comprises a movable window retractable in the door box, and which is sometimes associated with a fixed window. The fixed and mobile vibes are then separated from each other by a line of separation which, according to an art

  prior known, is constituted by a substantially vertical amount.

  However, the moving window of the opening must have a substantially constant radius of curvature, that is to say that the window must observe a cylindrical curvature to be able to slide inside the door box. Finally, for a rear door, the mobile window does not always lower completely because of the presence of the wheel arch which

  is housed in the lower part of the door box.

  Air-conditioning systems also tend to be standard equipment for motor vehicles, and car manufacturers are also very attached to the aesthetics or design of their vehicles by considering new forms for improving or not impair the aerodynamics of vehicles. From these observations, an aim of the invention is to modify the traditional design of the glazed part of the door openings, knowing that the technical solutions to be considered must privilege the generation of original shapes by putting a new tool at the disposal of stylists who

  be flexible enough to allow them to express themselves.

  For this purpose, the invention proposes a door leaf front or rear motor vehicle, this opening having a structure defining a door box at the bottom and a door frame at the top, at least one fixed window associated with at least a mobile window retractable into the door box, said vibes being separated from each other by a separating line, which is characterized in that the fixed window is rigidly connected to the door frame, and in that the separation line extends from the upper edge of the door box forming a line of leashes to return to said upper edge of the door box or

  end at a side jamb of the door frame.

  Advantageously, the door frame is not continuous all around the fixed window, and the fixed window is attached to the door frame and

  fixed rigidly to it by gluing or clipping, for example.

  According to an exemplary embodiment, the structure of the opening 25 comprises an inner structure and an outer structure which wind together against each other to form the door box at the bottom and the door frame at the top, so that the fixed glass is

  replaces the external structure of the opening at the door frame.

  Still according to this embodiment, the peripheral surface of the fixed window which is affixed to the interior structure of the opening has an opaque coating to hide the inner structure of the opening, this coating may be in the form of a banner in email

  or made of a painting deposited by serigraphy.

  When the fixed window is made of a synthetic material, it can integrate functional elements of thermoplastic material such as a mirror base, positioning pins of the fixed window, clips for holding or positioning the fixed window, joints eVou sealing a handle opening the opening example. In this case, it is possible to vary the thickness of the fixed window so as to mitigate

  possible optical distortions in very curved areas.

  According to an exemplary embodiment, the line of separation between the fixed and mobile vibes extends between two points respectively located on the upper edge of the door box forming a line of licks and a

  rear side jamb of the door frame.

  Moreover, the line of separation between the fixed and mobile vibes can be of any shape and present one or more radii of

different curvature.

  In a general manner, the separation line between the fixed and mobile vibes is constituted by a separation device which is integral or fixed to the door box eVou fixed to the fixed window, and comprises means

  Forming a slider for the moving window.

  In general, the mobile window can extend over a considerably smaller area than the fixed window. Indeed, when the motor vehicle is equipped with an air conditioning system, the driver quickly becomes accustomed to driving all vibes closed and the movable window is lowered only occasionally, when passing a terminal peage by

example.

  Furthermore, the movable window is generally located at the rear portion of the glazed portion to facilitate the exit of the arm of the driver or a passenger, which also offers the advantage that the line of separation

  does not enter the driver's field of vision during normal driving.

  An opening according to the invention also has other advantages, among which may be mentioned in particular: a reduction in the cost of the window regulator system for the mobile window because of its reduced dimensions; the possibility of producing the stationary window made of PMMA or PC, which results in a gain in weight making it possible to reduce the section of the door frame on which the mobile window is fixed, because this rear end reinforces the rigidity of the frame, in particular the section of the amount of bay which increases the field of vision of the driver; - Less aerodynamic deport since the glazed part can be located in the extension of the vehicle body; - the possibility of standardizing the mobile window module / window regulator system for front and rear door openings of different vehicles; to give greater flexibility in the design of the fixed window, since it occupies a surface area significantly greater than that of the moving window; the possibility of completely returning the moving window inside the door box for a rear door opening without being hampered by the door return for the wheel arch; and - to provide additional security by preventing a child from passing his body through the mobile window in a position

  lowered and when the vehicle is moving.

  Finally, an opening according to the invention makes it possible to significantly reduce the lateral overflow following the opening of the opening, in particular in the case of a "butterfly" type opening which is mounted

  articulates in the upper part of the vehicle body.

  Other advantages, characteristics and details of the invention

  compared to that shown in Figure 18.

  - An opening 1 of front or rear door of the traditional type as evoque in preamble presents a structure comprising a door box at the bottom and a door frame at the top, and its representation in Figure 1 was limited to the frame of door C which catches a

glazed part.

  In a general manner, the door frame C, like the door box of the opening 1, comprises an inner structure 3 and an outer structure 5 which can be constituted of two soles assembled against each other in particular by welding. The glazed part comprises a movable window Vm which cooperates with an extruded profile 6 forming a slide integral with the door frame C and mounted between or on the inner structures 3 and 5 outside the door box. A gutter seal 7 may be interposed between the door frame C and the vehicle body 8, for example the pavilion, and a door entry seal 9 is generally attached to the body of the vehicle. In the case where the glazed part V comprises a fixed window, it is reported inside the door frame C with the interposition of seals. According to an embodiment illustrated in FIG. 2, the external structure 5 of the door leaf 10 is retained only in the lower part forming the door box 12, and it is a fixed window Vf which replaces the the outer structure of the door opening 10 in its upper part forming the door frame C. The periphery of the fixed window Vf is affixed to the inner structure 3 of the opening 10 and fixed for example by means of an adhesive joint 13, so as to come in external cover on the inner structure 3. Alternatively, the fixing of the fixed window Vf could be provided by clipping. Advantageously, the peripheral surface of the fixed window Vf which comes into contact with the inner structure 3 of the opening 10 has an opaque coating 15 in the form of a black strip, for example, whose function is to hide the external view of the interior structure 3. This coating 15 email or made of a paint is deposited by screen printing for example. To perfect the non-vision of this interior structure, it can be reported a profile 17 forming hubcap to improve the aesthetics of the whole. A gutter seal 7 can ensure the transition between the fixed glass Vf and the body 8 of the vehicle on which is

  also reported a door entry seal 9.

  Figures 3 and 4 show the general appearance of a glazed portion V for a door opening 10 front PAV (Figure 3) and a door leaf 10 rear PAR (Figure 4). In addition, the vitreous part V comprises at least

  a movable window V ,, which will be described in detail below.

  When the fixed window Vf is made of a synthetic material, it is possible to integrate functional elements 20 of the type of those shown in FIGS. 5 to 7 described below. These functional elements may be constituted by a mirror base 21 (Figure 5), pins 22 for positioning the fixed window Vf on the inner structure of the opening 10 (Figure 6) or retaining clips or positioning the fixed window Vf, seals 23 (Figure 7) eVou opening a handle opening, for example. With a fixed glass Vf realized in a synthetic material, it is possible to vary its thickness so as to mitigate possible optical distortions in very curved areas of the glass. The motor vehicle illustrated in FIG. 8 and equipped with the front and rear door openings 10 of FIGS. 3 and 4, makes it possible to highlight some of the important advantages of the invention, namely that the fixed vibes Vf may have radii of curvature. different, especially at its edges. Indeed, the fixed window Vf occupying a surface significantly greater than that of the mobile window Vm, it can be given various shapes with different radii of curvature in its central part (radius R.), on its upper edge or return of pavilion of your '(radius R2), and on its lateral edge before or back towards the amount of bay

(radius R3), for example.

  In FIGS. 9 and 10 which illustrate the prior art evoked in preamble for the glazed portion, the opening 1 of the front door PAV and the rear door PAR comprises a fixed window Vf and a movable window Vm retractable in the housing of gate 12. The vibes fixed Vf and mobile Vm wind separated from each other by a separation line L which is materialized by a substantially vertical upright 25. The fixed glass Vf is reported inside the door frame C and the two ends of the upright 25 which separates the fixed vibrator Vf and the movable vibrator V ,, fixed to the door frame C by welding, screwing,

  riveting, clipping or gluing, for example.

  A first embodiment of the glazed portion V of an opening 10 of PAV front door and rear door PAR according to 1'invention is illustrated in Figures 11 and 12. According to the invention, the glazed portion is constituted by ['] combination of at least u fixed glass Vf which is strictly related to the door frame C, and a movable window Vm which is retractable in the door casing 12, the two vibes being separated one of the another by a

  separation line L of a particular type.

  In a general manner, the separation line L between the fixed window V and the movable window Vm is starting from the upper edge 12a of the door box 12 to return to said upper edge or end to a lateral amount of the door frame C. The line of separation L extends between two points P1 and P2 which are situated on a line D inclined at an angle α with respect to a vertical axis X - X. This line of separation L can have any rectilinear shape eVou curve, and all the features of this

  separation line apply to all embodiments of the opening 1

according to the invention.

  For the openings 10 according to Figures 11 and 12, the two points P1 and P2 of the separation line L wind respectively located on the upper edge 12a of the door box and on a rear side jamb 30 of the door frame C. D ' in a general manner, the separation line L between the fixed and mobile Vm vibes Vm is constituted by a separation device 40, several embodiments of which are described below with reference to FIGS.

Figures 13 to 13b.

  According to a first exemplary embodiment illustrated in FIG. 13, the separation device 40 comprises at least one rigid upright 42 which marries the shape of the separation line L. The upright 42 can be integrated or brought back and fixed to the door frame C The fixed pane Vf, along its side corresponding to the line of separation L, is stuck to this upright 42 by an adhesive joint 44, for example. The separation device 40 also comprises a plastic or rubber profile 45 which comprises, by way of example, a sliding glazing slider 47 of U-shaped cross-section and integral with a support 48 also of shaped cross-section. U which is anchored on a projecting edge of the upright 42. The fixed window Vf is thus fixed by

  continuous way all around.

  According to an alternative embodiment illustrated in FIG. 13a and in a flush mounting, the slide 47 is a half-U, so that the separation device 40 is situated on the same side of the vibes Vf and vm. embodiment shown in Figure 13b, the separation device 40 no longer includes a rigid amount as in the first embodiment. The separation device 40 is constituted by a profile 50 of plastic or rubber which has in cross section an H-shape with two upper lips L, between which the fixed window Vf engages and two lower lips L2 forming a slide 47 for the mobile window Vm. The body of the profile 50 can be

reinforced by a frame 52.

  According to a second embodiment of the invention illustrated in FIG. 14 for a front door PAV, the frame of the door C is not continuous all around the fixed window Vf and it is limited to the upper edge 12a of the housing. door 12, has a rear lateral amount 30 and has a lateral amount before 56. The two points P1 and P2 of the separation line L between the fixed vibrator Vf and mobile Vm wind respectively located on the upper edge 12a of the door box 12 and on the rear lateral pillar 30 of the door frame C. The fixed window V is fixed on the upper edge of the door casing 12 and on the lateral rear pillars 55 and before 56 by adhesive joints 57. The separation device 40 between the fixed and mobile Vm vibes Vm can be realized according to the exemplary embodiment illustrated in FIG. 13b, that is to say without the presence of a rigidity amount reported or integrated in FIG.

door box 12.

  According to a variant embodiment illustrated in FIG. 14a, the separation device 40 between the fixed vibrating Vf and mobile vibrating Vm is of the type of that illustrated in FIG. 13 or 13a with the presence of a rigid upright. Furthermore, it must be ensured that the fixed window Vf is securely fixed to the door casing 12 and, for this purpose, its bonding area can be increased by extending the fixed window Vf inside the door casing 12, as is also

illustrates in Figure 14a.

  According to a variant embodiment illustrated in FIGS. 15 and 16 for an opening 10 of front door PAV, the two points P 'and P: between which stetend the separation line L between the fixed vibrating Vf and mobile Vm wind located on the edge upper 12a of the door box 12, and the separation line L has a U-shaped reverse. Furthermore, to increase the bonding surface of the fixed window Vf, it can be further penetrated inside the door box 12. The separation line L is formed by a profile 70 in the shape of a U which presents in H-shaped section that is fixed to the fixed window Vf on the one hand and which forms a slide for the mobile window Vm on the other hand. The profile 70 can be reinforced by a metal frame or

in plastic.

  In FIGS. 17a to 17f, various possible forms have been illustrated for the glazed portion of an opening 10 of front door PAV OR rear PAR and which is surrounded by a door frame C secured to the door casing 12, these forms also applying to a glazed part not surrounded by a firm door frame. In FIGS. 17a to 17c, the points P1 and P2 of the separation line L between the stationary window glass Vm and the moving window glass Vm respectively lie on the upper edge 12a of the door box 12 and on a rear lateral pillar of the door frame C. , tent for a front door PAv (Figures 17a and 17c) that

  for a rear door PAR (Figure 17b).

  In FIGS. 17d to 17f, the two points P1 and P2 are situated on the upper edge 12a of the door box 12, knowing that the presence of several mobile vibrator Vm can be envisaged (FIG. 17fl, one or the two points P1 and P2 of the separation line L respectively wind located on the upper edge 12a of the door box 12 and on

the lateral amount before 56.

  In a traditional manner, a front or rear door leaf is mounted hinged to the vehicle body to pivot most often around a vertical axis or a substantially horizontal axis (opening type "butterfly" or the wind joints located in the upper part of the body), and its opening entails a relatively large lateral overflow. Moreover, this lateral overflow is all the more important in the presence of a large moving window of the moment when it must

  retract completely inside the door box.

  A traditional door 1 of butterfly type is shown in Figure 18 to show the lateral overflow following the opening of the opening 1 which is mounted articulated by means 80 located in the upper part.

  of the vehicle body at the pavilion of your '82 for example.

  Now, the concept of a fixed window associated with a movable window according to the modalities of the invention which have been previously described will

  allow to significantly reduce this lateral overflow d.

  Indeed, the movable window Vm of an opening according to the invention being most often small, it is thus possible to reduce the height of the door box on the one hand and to increase the glazed area by extending the window fixed in the upper part towards the pavilion of your ', towards the amount of bay eVou towards the rear window on the other hand. More specifically, with reference to FIG. 19a, the fixed window Vf can in particular be extended in the upper part and with a radius of curvature so as to have a return towards the pavilion of tone 82 such that the articulation means 80 can thus be close to the vertical median plane P of the vehicle, which will result in a lateral overflow of less than

  overflow d of Figure 18 to the opening of the opening 10.

  The nature of the hinge means 80 of the opening 10 depends on their positions. For example, conventional hinges may be used when the hinge axis is substantially horizontal and located at the level of the return to the pavilion of your '82 tent for an opening 10 of front door or rear door, kneecaps or hinge means 82a of a type rods or a cylinder when they are located on the lateral amount of bay 84 or the lateral amount 86 of the rear window, as is

  schematically illustrated in Figure 1 9a.
