DETAILED DESCRIPTION OF EMBODIMENTS

[0052] The invention therefore relates to a motor-vehicle door and in particular the glazed part thereof, which is flush, that is to say no frame or frame element projects towards the outside of the vehicle with respect to the plane of this glazed part.

[0053] The embodiment described below relates to a front side door.

[0054] However, naturally, the same approach can be implemented on other doors of a vehicle.

[0055] This door comprises conventionally a door chamber, forming the structure of this door. The chamber comprises a first top frame, which defines an opening, and is connected to a bottom part that comprises in particular elements for receiving and holding the glazed part.

[0056] This glazed part, or glazed device, 12 is produced independently, as illustrated in FIG. 2, and next assembled with the chamber, in order to form the door.

[0057] The glazed part 12 is configured so as to offer a flush appearance.

[0058] This comprises a movable glazed panel 121, able to be moved from a closed position to an open position. In FIG. 2, the movable part is in the closed position.

[0059] This glazed part 12 comprises a second frame that has substantially the same form as the first frame of the door structure.

[0060] This second frame has a top cross member 213 following the curve of the top part of the glazed part and connecting two uprights each formed by a rail 22.sub.A, 22.sub.B for sliding guidance of the movable glazed panel 121, a central cross member 215, and a front element 214 intended to be associated with a fixed glazed part (not illustrated).

[0061] It should be noted that the rails 112.sub.A, 112.sub.B constitute structural elements of the glazed part 12.

[0062] The movable glazed panel 121 is moved by drive means (not illustrated), for example a rack mechanism, actuated itself by an electric motor (not illustrated). These drive means are situated in the bottom part of the door chamber. Other drive means, including manual drive means, may of course be used.

[0063] Guide shoes are fixed to the face of the movement panel 121 oriented towards the inside of the vehicle, in order to cooperate with the rails 22.sub.A, 22.sub.B. Although in practice they are generally not visible from outside (the corresponding zone being screen printed), the positions thereof have been shown in FIG. 2.

[0064] In this embodiment, a single shoe 26 for guidance along XY is provided for cooperating with the rail 22.sub.A oriented towards the rear, and a single shoe 27 for guidance along Y is provided for cooperating with the rail 22.sub.B oriented towards the front.

[0065] The rear shoe 27 has, according to this embodiment, an essentially cylindrical cross section. The rail 22.sub.A has an essentially cylindrical complementary shape. Thus the respective cross sections of the shoe and of the rail allow a rotation of the movable panel about the axis Z. This cylindrical shape can in particular facilitate assembly and tolerate clearances.

[0066] According to a particular embodiment, said shoe is overmoulded on a metal insert.

[0067] The overmoulding can in particular be carried out in polyoxymethylene (POM).

[0068] The glazed part 12 is assembled independently of the door chamber, and then mounted on the latter by fixing the top cross member 213 and the rails 22.sub.A, 22.sub.B on the chamber.

[0069] A door that can be mounted directly on the vehicle is then available.

[0070] The second frame may carry a plurality of seals 31, (seen in cross section in FIG. 5). It also receives a trim element, or finishing element, 56 extending in the plane of the movable glazed panel 121 when the latter is in the closed position.

[0071] More precisely, the rear guide rail 22.sub.A receives a trim 56, which is positioned so as to be aligned with the edge 121.sub.A of the movable glazed panel 121 while minimising the clearance J with the latter, for aesthetic reasons.

[0072] The trim 56 has a plurality of centring elements 561 projecting from its internal face cooperating with apertures provided in the rail 22.sub.A. It further has locking elements (not visible) in order to hold the trim 56 in position on the rail 22.sub.A during use of the vehicle, and to prevent its becoming dismantled under the effect of shocks or vibrations. The trim 56 can also be easily dismantled.

[0073] The trim 56 is mounted directly on the rear guide rail 22.sub.A, unlike the trims of glazed devices of the prior art, which are fixed to the vehicle door structure. It can be fixed to the rail 22.sub.A before or after assembly of the glazed part 12 on the vehicle door chamber. The trim 56 can easily be assembled on the glazed part 12 directly at the suppliers.

[0074] In the case where the window guide rails 22.sub.A, 22.sub.B and the window-winder rail (not illustrated but secured to the fixing points 122 situated at the bottom part of the glazed panel 121) are not assembled on the same station, and it is necessary to compensate for any defects in assembly of the window winder by providing a window/window-winder connection allowing a relative movement along at least the axis X.

[0075] However, this degree of freedom necessary for the correct functioning of the system does not make it possible to provide a clearance along X between the glazed panel 121 and the trim 56 at the bottom part (at the top part, clearance is guaranteed by the guide shoe 26 along XY).

[0076] As illustrated in FIG. 3 (seen from the outside), the invention provides for the rear rail 22.sub.A to carry a stop 57 for blocking the glazed panel 121 in the longitudinal direction X of the vehicle (and more precisely in the direction X).

[0077] The blocking stop 57 is mounted on the rail 22.sub.A in the vicinity of the bottom end of the latter. This blocking stop 57 blocks any movement along X of the glazed panel 121, without opposing the sliding of the latter along Z. In other words, this stop 57 for blocking along X situated at the bottom part of the rail 22.sub.A blocks the movement of the glazed panel 121 along X with respect to the window-guide rail 22.sub.A.

[0078] As illustrated by FIG. 4, which is a view in cross section AA level with the blocking stop 57, the latter has a first portion carrying a fixing element 571 intended to be snapped into an aperture in the rail 22.sub.A. The first portion is extended by a second portion, which covers the rear lateral edge 121.sub.A of the glazed panel 121, from the outside.

[0079] In the example illustrated, this second portion comprises a first lug, disposed on the outside of the glazed panel, and the internal surface of which that is turned towards the glazed panel 121 is in the form of an angle bracket.

[0080] The first lug has a first blocking surface 572 extending in the transverse direction Y of the vehicle and against which the edge of the glazed panel 121 comes into abutment. This first blocking surface 572 blocks any movement of the glazed panel 121 along X, which makes it possible to preserve a minimal clearance between the top and bottom parts (along the axis Z) of the trim 56 and the rear lateral edge 22.sub.A of the glazed panel 121.

[0081] The first lug also has a second blocking surface 573 extending in the longitudinal direction X of the vehicle and against which the external surface of the glazed panel 121 comes into abutment, so as to prevent any movement of the glazed panel 121 towards the outside in the transverse direction Y of the vehicle. This blocking along Y at the bottom part of the glazed panel 121 compensates for the action of the seals, which have a tendency to push the glazed panel 121 outwards.

[0082] The blocking stop 57 thus provides blocking in two directions X and Y+.

[0083] FIG. 6 presents a second embodiment of the blocking stop 57. The latter has two lugs defining a U-shaped slot 575 in which the rear lateral edge 121.sub.A of the glazed panel 121 is housed, the lugs being disposed on the inside and outside respectively of the glazed panel 121. This slot 575 is delimited by first and second blocking surfaces 572, 573 and a third blocking surface 574.

[0084] The third blocking surface 574 extends in the longitudinal direction X of the vehicle, parallel to the second blocking surface 573. The distance between the second and third blocking surfaces 573, 574 is slightly greater than the thickness of the glazed panel 121 so as to allow a movement of the glazed panel 121 with small clearance in the transverse direction Y of the vehicle. This moreover prevents the movable glazed panel 121 being able to be offset towards the inside by an ill-intentioned person, when it is in the closed position.

[0085] The blocking stop 57 thus provides blocking in three directions X, Y+ and Y.

[0086] At least one of the blocking surfaces 572 to 574 is covered with a layer of additional material having a low coefficient of friction and high resistance to wear, such as polyoxymethylene.

[0087] In variants, it may be a layer of felt or a polyurethane strip.

[0088] In another variant, the stop 57 is a single-material piece.

[0089] The glazed assembly may also comprise one or more fixed glazed panels, or quarter lights.

[0090] In a particular embodiment, the movable glazed panel carries, on its face oriented towards the inside of the vehicle, two guide shoes each mounted so as to be able to slide with respect to a guide rail.

[0091] In another particular embodiment, the movable glazed panel carries a single guide shoe cooperating with one of the two guide rails in which the movable glazed panel slides.

[0092] Many additions or variants to the embodiment described above can of course be envisaged.

[0093] The rails may be configured so as to guide the movable glazed panel in a turning and sliding movement, so as to slightly move the movable glazed panel, during its movement, away from a frame or an upright against which it is in abutment, in a closed position.

[0094] In this case, at least one of the guide rails carries a ramp, providing the turning.

[0095] Other forms of stops may of course be used without departing from the scope of the invention. In all cases, they allow blocking in at least one direction, along X and where applicable along Y.

[0096] Moreover, the blocking stop 57 may be carried by the trim 56, itself being mounted on the rail 22.sub.A.
