Definitions

• the field of the invention is that of blackout blinds for a motor vehicle door. More specifically, the invention relates to retractable blinds intended to equip a door with at least two substantially adjacent panes.
• window is meant here more generally any element of which at least a portion is substantially transparent or translucent.
• Removable blackout curtain blinds such as roll-up curtain blinds deployable and collapsible, depending on whether or not it is desired to obscure the light, are conventionally used for concealing the glass surfaces of a glass pane. side door.
• roller blinds can be implemented in relation to any glazed surface, for example a quarter window, and to hide a space, for example in the form of a luggage cover.
• roller blinds generally comprise a curtain mounted on a roller tube, itself rotatable through two bearings.
• These bearings can be directly attached to the structure of the vehicle or mounted in a housing, or cassette, receiving the retractor and the blackout curtain when is folded.
• This housing is then secured to an element of the vehicle, either directly on a structural element, or to an element of the interior lining, and for example to the door panel of a door.
• a pull bar is generally associated with the other end of the blackout curtain, to allow its deployment. Fastening means or holding the pull bar can hold the curtain in its extended position, in which it hides the glass part. Returning means act on the retractor tube, tending to bring the curtain back into the folded position.
• the deployment of the curtain, as well as its withdrawal, can be manual or motorized.
• the draw bar can be guided by two rails in which slide each of its ends.
• Such rails are generally integrated into the vehicle and are mounted and / or concealed in the interior lining of the vehicle, and for example in the trim of the door panel of a door.
• a first disadvantage of this technique is that for current door windows, which are commonly curved or curved, at least in the width direction (transverse curve) and sometimes also in the longitudinal direction, the floating guide of the curtain can do not allow it to be properly held in the extended position along the surface of the window. Indeed, a gap between the curtain and the window can appear, which is likely to let the light in the cabin and is not satisfactory in terms of aesthetics.
• a second disadvantage of this technique lies in the fact that it generally requires a security preventing the roll of the blind from being deployed in front of a sliding window if the window is not completely raised, in order to avoid damaging the curtain which without the the obstacle presented by the surface of the window, curved, unfolds in a rectilinear manner in the vertical direction.
• a third disadvantage of this technique is that it requires the implementation of solutions that can be complex, to hide the sight of the guide rods from the inside or outside of the vehicle, in order to to give a suitable aspect, and in particular smooth, to the curtain.
• the displacement of the draw bar is implemented by means of a pantograph secured to one of these ends of the draw bar and unfoldable in a plane substantially parallel to that of the window.
• the invention therefore particularly aims to overcome the disadvantages of the prior art mentioned above. More specifically, the invention aims to provide a technique of concealment of two adjacent door windows, and in particular a sliding side window and a fixed quarter window, by a single curtain.

• the invention proposes, in a new and inventive way, a simplified control and guidance technique for the deployment or folding of an occultation curtain requiring the implementation of a limited number of elements, to jointly cover two windows adjacent door.
• the draw bar may be progressively inclined during its displacement, so as to be oriented substantially in the direction of the edge of the lower frame or the upper frame of the door panel bay, which are generally non-parallel, in position folded, respectively deployed.
