DETAILED DESCRIPTION OF AN EMBODIMENT

[0050] The invention therefore relates to a new technique making it possible to produce a motor vehicle door (side door, rear door, hatch, cabin door, and so on), the glazing, or mobile panel, of which is perfectly aligned and flush with the vehicle body.

[0051] As shown in FIGS. 1 and 2, the embodiment described below relates to a front side door of a vehicle. However, of course, the same approach may be used on other doors of a vehicle.

[0052] Said motor vehicle door, and, in particular, the glazed portion thereof, is flush, i.e. no frame or frame element projects toward the outside of the vehicle, with respect to the plane of said glazed portion.

[0053] Said door 1 conventionally includes a door casing or chassis 10, forming the structure of said door. The casing 10 includes an upper frame 103, which defines an opening 102, and which is connected to a lower portion 101. In the figures, the exterior element of the vehicle body is omitted, so as to show the interior of the lower portion 101 of the casing 10, which includes in particular elements for receiving and holding the glazed portion 11.

[0054] Said glazed portion 11 is produced independently, as shown in FIG. 2, and then assembled to the casing 10, in order to form the door 1.

[0055] The glazed portion 11 includes a frame having an upper cross member formed by the upper portion 115.sub.C of a seal 115, with the upper portion 115.sub.C connecting two jambs each formed by a guide rail 112.sub.A, 112.sub.B by sliding a mobile glazed panel 110 and a central cross member 113.

[0056] The seal 115 has the form of a continuous strip. The curvature of its upper portion 115.sub.C corresponds to that of the upper frame 103 of the casing 10, with this upper portion 115.sub.C forming a cross member.

[0057] The seal 115 further comprises two straight branches 115.sub.A, 1153 extending in parallel from this upper portion 115.sub.C.

[0058] The mobile glazed panel, or glazing, 110, may be moved in a substantially vertical direction between: [0059] a closed position, in which it closes the opening 102 formed in the upper frame 103 of the casing 10, its lower periphery 110.sub.D remaining inserted in the thickness (i.e. in the lower portion 101) of the casing 10, the upper edge 110.sub.C coming into contact with one or several sealing lips of the glazing 115.sub.E which will be described below, the front 110.sub.B and rear 110.sub.A edges being located in the rails 112.sub.A, 112.sub.B; [0060] an open position, in which it frees the opening 102 and is completely or partially retracted in the thickness of the casing 10, and [0061] intermediate positions.

[0062] It is noted that the rails 112.sub.A, 112.sub.B constitute, as the upper portion 115.sub.C of the seal 115 when the latter is rigid, structural elements of the glazed portion 11.

[0063] The two rails 112.sub.A, 112.sub.B, which are made of plastic, aluminum, steel or any other suitable material, are mounted by screwing, riveting, clipping or any other suitable technique on two fastening lugs 123.sub.A, 123.sub.B integral with the seal 115.

[0064] The glazed portion 11 is assembled independently of the door casing 10, then mounted on the latter by attachment of the seal 115 forming the upper cross member and the rails 112.sub.A, 112.sub.B on the casing 10.

[0065] Thus, a door 1 capable of being mounted directly on the vehicle is obtained.

[0066] To ensure the seal between the casing 10 of the door 1 and the mobile glazed panel 110 when the latter is in the closed position (so as to prevent water or other elements from entering the vehicle), one or several sealing lips of glazing 115.sub.E are provided on the peripheral seal 115 (called slide), and more particularly on the upper portion 115.sub.C and the two branches 115.sub.A, 115.sub.B of the seal 115, which come into contact with the contour of the mobile glazed panel 110.

[0067] One or several sealing lips of the door 115d are arranged on the top (i.e. on the upper surface) of the upper portion 115.sub.C in such a way as to be compressed between the upper portion 115.sub.C of the seal 115 and the body of the vehicle (referenced as C in FIG. 3) when the door 1 is closed, which provides a good seal.

[0068] The sealing lip or lips of the door 115d and the sealing lip or lips of the glazing 115e are produced in a single piece with the upper portion 115.sub.C and the two branches 115.sub.A, 115.sub.B.

[0069] The upper portion 115.sub.C of the seal 115 is either rigid and then forms a structuring element that has a relatively high mechanical resistance and exerting a rigidifying function of the frame, or flexible.

[0070] As shown in the cross-section views of FIGS. 3 and 4, the glazing sealing lip or lips 115e are attached on the bottom (i.e. on the lower surface) of the upper portion 115.sub.C and on and on the inner edge of the rails 112.sub.A, 112.sub.B, so as to be concealed below the mobile glazed panel 110 when it is closed.

[0071] The glazing seal lip or lips 115e are then compressed between the upper frame 103 of the casing 10 and the mobile glazed panel 110, which ensures a good seal.

[0072] It is noted that, in the example shown in FIG. 3, that the four glazing sealing lips 115e come into contact with the upper edge 110.sub.C of the mobile glazed panel 110, which is closed.

[0073] It is also noted that, in FIG. 3, that the upper portion 115.sub.C of the seal 115 has a U-shaped interior groove 111, in which an edge of the upper frame 103 of the casing 10 is housed during assembly of the glazed portion 11 on the casing 10.

[0074] The mobile glazed panel 110 is moved by driving means (not shown), for example a rack mechanism, itself actuated by an electric motor. Other driving means, including manual driving means, may of course be implemented.

[0075] Guide glides are attached on the face of the mobile glazed panel 110 oriented toward the interior of the vehicle. Said guide glides are intended to cooperate with rails 112.sub.A, 112.sub.B and guide the rear 110.sub.A and front 110.sub.B edges of the mobile glazed panel 110 in the rails 112.sub.A, 112.sub.B. In practice, said glides are not generally visible from the outside (the corresponding area being screen-printed). In this embodiment, two glides 116 and 117 are intended to cooperate with the rail 112.sub.A oriented toward the rear, and a single glide 118 is intended to cooperate with the rail 112.sub.B oriented toward the front.

[0076] The guide rails 112.sub.A, 112.sub.B ensure the dual function of guiding in translation and tacking. Said tacking, which is not imperative in all embodiments, makes it possible to slightly offset the mobile glazed panel 110 toward the outside, before it is moved in translation, so as to release it from the seal 115, in order to facilitate the movement and limit the deterioration of the latter.

[0077] It is noted that, in FIG. 4, the glide 116 attached to the mobile glazed panel 110 is arranged in the rail 112.sub.A and the branch 115.sub.A of the seal 115 is clipped to the edge of the rail 112.sub.A oriented toward the mobile glazed panel 110.

[0078] The branch 115.sub.A of the seal 115 has a first glazing lip 115e coming into contact with the rear edge 110.sub.A of the mobile glazed panel 110, which is closed, and a second door lip 115d covering the frame of the casing 10.

[0079] It is understood that, similarly, the branch 115.sub.B of the glazing seal 115 located on the rail 112.sub.B, has a glazing lip 115e coming into contact with the front edge 110.sub.B of the mobile glazed panel 110 and a door lip 115d covering the frame of the casing 10.

[0080] The frame of the glazed portion 11 also has: [0081] a central cross member 113 connecting the guide rails 112.sub.A, 112.sub.B and which is screwed, for example, to the top of the lower portion 101 of the casing 10, and [0082] a seal, namely an interior tongue 119 (attached to the central cross member 113) which is intended to come into contact with the interior surface of the mobile glazed panel 110, and which is intended to prevent water or other elements from entering the thickness of the casing 10.

[0083] The frame of the glazed portion 11 also has, in this example, a cap element 121 extending in the plane of the mobile glazed panel 110 when it is in the closed position, and an exterior rearview mirror base 122.

[0084] The door may have a shade.

[0085] The glazed assembly may also include one or more fixed glazed panel(s) or quarter panel(s).

[0086] In a specific embodiment, the mobile glazed panel has, on its face oriented toward the interior of the vehicle, two guide glides each slidably mounted with respect to a guide rail.

[0087] In another particular embodiment, the mobile glazed panel has a single guide glide cooperating with one of the two guide rails in which the mobile glazed panel slides.

[0088] FIG. 5 schematically shows the steps of an embodiment of the method for producing a motor vehicle door according to the invention.

[0089] In this example, the method includes the following steps: [0090] production (step E1) of a door casing 10; [0091] production (step E2) of a glazed device 11 including at least one mobile glazed panel 110 and guide rails 112.sub.A, 112.sub.B by sliding the mobile glazed panel 110 between a closed position and at least one open position, with the mobile glazed panel 110 having, on its face oriented toward the interior of the vehicle, at least one guide glide 116, 117, 118 slidably mounted with respect to one of the guide rails 112.sub.A, 112.sub.B, said guide rails 112.sub.A, 112.sub.B being connected in their upper portion by an upper cross member formed by the upper portion 115.sub.C of a seal 115, [0092] assembly (step E3) of the door casing 10 and of the glazed device 11.

[0093] It is noted that the step (E2) of producing the glazed device 11 includes: [0094] a step of producing (E20), in a single piece, the upper portion 115.sub.C forming a cross member and two branches 115.sub.A, 115.sub.B of the seal 115, with the upper portion 115.sub.C carrying one or more sealing door lips 115d, and one or more glazing sealing lips 115e. [0095] a step of placing (E21) guide rails 112.sub.A, 112.sub.B on two fastening lugs 123.sub.A, 123.sub.B of the seal 115, with the guide rails (112.sub.A, 112.sub.B) being attached to two fastening lugs 123.sub.A, 123.sub.B by screwing, riveting or clipping, for example.

[0096] Note moreover that the step of assembling (E3) of the casing of the door 10 and of the glazing device 11 comprises a step of inserting an edge of the casing of the door 10 into the slot 111.sub.A of the upper portion 115.sub.C of the sealing device 115.

[0097] Numerous additions or alternatives to the embodiment described above may of course be envisaged.
