Description

<Desc / Clms Page number 1>

 Roller blind, in particular for motor vehicles, intended to selectively conceal two portions of glazed surface, door and corresponding vehicle.

 The field of the invention is that of roller blinds for motor vehicles (cars, utility vehicles, trucks, buses, etc.). More specifically, the invention relates to the selective concealment of at least two portions of glass surface, corresponding for example to two parts of a bay of a rear door of the vehicle, separated by a central spar.

 In a manner known per se, a roller blind comprises a curtain or canvas, forming a screen in the deployed position. One end of this fabric is mounted on a roller or winding tube movable in rotation. The other end of the canvas has a pull bar. All of these elements can be mounted in a housing or on a support, a passage being provided through which the fabric can be moved. In the folded position, the fabric is essentially wound around the winding roller and the draw bar is therefore in the vicinity of this roller.

 In some cases, the blind is operated manually, and the user then acts on the pull bar so as to move it away from the winding roller. The folding is then obtained by the action of a return spring driving the winding roller. In other cases the blind is motorized.

 In general, the blind is mounted on a structural element of the vehicle, for example the door. For example, it is housed on, or inside the door casing. The awning fabric can then be deployed, from bottom to top, to hide at least most of the bay.

 The blind can also be mounted on a lateral edge of the opening, and can be deployed horizontally, up to the other edge of the opening.

 In some cases, however, there may not be enough space to place a shade box at the edge of the bay (either below, above, or to one side), or simply that it is not desirable to mount a blind on an edge, for example for reasons

<Desc / Clms Page number 2>

 aesthetic and / or ergonomic.

 Thus, for example, it may happen that the bay of a door has a central, vertical spar, dividing the bay into two glazed portions, and that this spar is the only available location, or the most efficient, for mounting means of occultation.

 A problem then arises: a conventional blind fabric can only obscure one of the glazed portions. This is ineffective, and unacceptable in practice.

 One can of course consider mounting two blinds one next to the other on the separation beam, allowing each one of the two windows to be blinded independently.

 However, this approach has several major drawbacks. First, this solution requires the implementation of two complete blinds and is therefore expensive.

 Secondly, there is the problem of the size of this solution.

Indeed, the space required for the installation of two blinds therefore, and hardly compatible with the space available.

 This would result in a solution which proves difficult to implement, or leads to an unsightly result, and not ergonomic. In particular, it is likely to reduce the space available inside the vehicle for passengers.

 The invention particularly aims to overcome these various drawbacks of the state of the art.

 More specifically, the invention aims to provide a blind intended to selectively conceal two portions of glass surface.

 In particular, an objective of the invention is to provide such a blind, which can be implemented effectively from a central spar separating the bay.

 The invention also aims to provide such a blind which is relatively simple to make and assemble, and which, consequently, does not generate a significant increase in cost.

 The invention also aims to provide such a blind, which is aesthetic

<Desc / Clms Page number 3>

 and ergonomic.

 Yet another objective of the invention is to provide such a blind, which has a reduced weight and size (compared to two adjoining blinds).

 The invention also aims to provide such a blind that is easy to implement and simple to use.

 These objectives, as well as others which will appear subsequently, are achieved according to the invention using a roller blind for a motor vehicle mounted in a housing containing a single winding tube and adapted to selectively allow a development of a blackout fabric mounted on said tube in front of a first or a second portion of glazed surface extending respectively on either side of said housing.

 Thus, it is possible to obscure the desired part of the bay, for example as a function of the direction of the sun's rays, by using only one winding tube, which makes it possible to reduce costs, l size and weight.

 According to a first advantageous embodiment of the invention, the box comprises a support and a movable cover between two positions, relative to said support, so as to allow respectively deploying said blackout fabric in a first and a second direction, forming an angle between them of the order of 180, so as to selectively obscure the first or the second portion of the glazed surface.

 The displacement of the cover makes it possible to limit friction, and therefore wear, of the fabric along this cover, or of the housing.

 Preferably, in this first embodiment, said cover is mounted for rotation on an axis parallel to that of said tube.

 Said cover can in particular take: a rest position, in which it defines with said support a slit for passage of said concealment fabric allowing its deployment in said first direction; and a tilted position, in which it allows the deployment of

<Desc / Clms Page number 4>

 said canvas in said second direction.

 Preferably, said cover is held in said tilted position by said blackout fabric, when the latter is deployed in said second direction.

 Advantageously, return means tending to return said cover to its rest position are provided.

 According to an advantageous characteristic of the invention, the free end of said fabric is provided with a draw bar whose shape, size and / or attachment means are adapted so that said draw bar can be secured to structural elements of the vehicle present on the edge respectively of the first or the second portion of glazed surface.

 According to other embodiments of the invention, the blind also allows the simultaneous concealment of said first and second portions of glass surface.

 Thus, according to a second embodiment, the blind comprises two blackout fabrics mounted on said single winding tube, which can be deployed respectively in front of said first and second portions of glazed surface.

 Said housing then preferably has two openings allowing respectively the passage of said two blackout fabrics.

 Said housing can also advantageously have a wing which comes to bear against the fabrics wound on said winding tube.

Preferably, said wing is elastic, so as to remain in permanent contact with said fabrics, whatever the thickness wound.

 According to a third embodiment of the invention, the blind comprises a first pull-up bar mounted at the free end of a single blackout screen, and making it possible to deploy said screen opposite said first portion of glazed surface, and a second pull-up bar mounted so that it can drive said canvas to allow it to be deployed opposite said second portion of glazed surface, leaving said blackout canvas free in

<Desc / Clms Page number 5>

 translation.

 It is thus possible to selectively conceal one or the other of the glazed portions, or both, using a single canvas.

 Preferably, said second draw bar carries a guide axis along which said blackout fabric can circulate. Advantageously, this guide axis is free to rotate.

 Said housing can advantageously comprise, or cooperate with, a cover having two openings, from which said first and second pull bars allow respectively deploying said blackout fabric.

 According to a particular aspect of the invention, said housing is advantageously designed to be mounted on a spar of the structure of said vehicle (for example of a door), said spar separating a bay in a first and a second portion of glazed surface.

 The invention also relates to the doors of a motor vehicle equipped with a roller blind as described above, and / or means for receiving such a blind.

 Such a door may in particular have a spar separating a bay into a first and a second portion of glazed surface, on which said roller blind is mounted.

 According to a particular embodiment of the invention, said spar extends substantially vertically.

 The invention also relates to motor vehicles comprising at least one door and / or at least one roller blind as described above.

 Other characteristics and advantages of the invention will appear more clearly on reading the following description of four embodiments, given by way of illustrative and nonlimiting examples, and of the drawings among which - FIGS. 1 to 3 illustrate schematically a first embodiment of the invention, implemented on a door including the bay

<Desc / Clms Page number 6>

 has two portions separated by a vertical upright or spar; - Figure 4 provides a perspective view of the support and the cover of a blind according to the embodiment of Figure 1; - Figures 5 to 7 illustrate, in section, different phases of use of the blind of Figure 4; - Figures 8 to 10 illustrate, in section, three phases of use of a blind according to a second embodiment of the invention; - Figure 11 shows more precisely the two wound fabrics, according to the second embodiment of Figures 8 to 10; - Figures 12 to 14 illustrate, in section, three phases of use of a blind according to a third embodiment of the invention.

 Illustrated in Figures 1 to 3, a first embodiment of a blind according to the invention, intended to be mounted on a beam 1, which separates the bay from a rear vehicle door in a first portion 2 of a second portion 3.

 According to the application shown, these bay portions 2 and 3 are formed in a rear door 4 of a motor vehicle, the casing 6 of the blind being mounted on a vertical beam 1. It will however be noted that the invention can be applied to bays provided in other locations of the vehicle, such as in particular the front doors, tailgates, roofs, etc.

 According to the invention, means are therefore provided for passing from an unobstructed situation of the two bay portions (FIG. 3) to a situation concealed either of one or the other of the bay portions (FIGS. 1 and 2 ). As will be described later, the invention also makes it possible, in certain embodiments, to conceal the two bays simultaneously.

 It can be noted in these figures that the shape and size of the fabric 7 and / or of the pull bar 5 are defined so that they are compatible with the two portions of glass. Likewise, the attachment means for maintaining in the deployed position are compatible with the two positions, or two specific means are provided.

According to a first embodiment illustrated in FIG. 4, the blind

<Desc / Clms Page number 7>

comprend un boîtier 41 et un couvercle 42, le boîtier 41 étant destiné à être monté sur le longeron 1, ou à être logé dans celui-ci.

comprises a housing 41 and a cover 42, the housing 41 being intended to be mounted on the spar 1, or to be housed therein.

This housing 41 incorporates any suitable means for conventionally receiving in itself a roller for rolling up the blind (not shown).

As illustrated in FIG. 5, the cover 42 provides, in its rest position, a passage through which the fabric 51 is capable of being deployed / folded back.

According to this embodiment, the cover 42 is movable relative to the housing 41 so as to orient the passage through which the fleece is deployed or folded back, alternately in the direction of one or the other opening 2, 3.

To do this, the cover comprises pins 421 intended to be housed in recesses 411 of the housing 41. The cover 42 is thus mounted for rotation on the housing 41.

In this way, the cover can be positioned relative to the housing so as to allow the deployment / folding of the fabric, using the draw bar 52, facing one or the other of the two portions of bays (Figures 6 and 7).

The deployment is done in a conventional way to hide the first portion of bay (to the left in the figures), as illustrated in FIG. 6.

To deploy the fabric opposite the other bay portion (to the right in Figure 7), the cover 42 is pivoted around its axes 421 so that it occupies the tilted position illustrated in Figure 7.

In the embodiment illustrated in Figure 7, the cover 42 is held in its tilted position by contact with the fabric. It can also be provided that the pivoting of the cover can be continued, for example, until a configuration substantially symmetrical to that illustrated in FIG. 6 is obtained.

The return from the tilted position of the cover 42 illustrated in FIG. 7 to the rest position of FIG. 6 is advantageously ensured by elastic return means 422, housed on, or in, the cover. When the blind is folded back, we therefore obtain by default a configuration as shown in FIG. 5.

<Desc / Clms Page number 8>

 In this folded back position, the draw bar 52 comes to bear on an extension 412 of the housing 41, this extension forming a stop for the draw bar.

 According to a second embodiment illustrated by FIGS. 8 to 10 which allows the simultaneous concealment of the two bay portions, the blind comprises two fabrics 51, 53, each being secured by one of their ends to the same roller 56, and provided each at their other end of a draw bar 52,54.

These fabrics 51, 53 are rolled up one on the other in the folded position of the blind.

 It is noted that the support 81 of the roller 56 has a base 811, intended to be fixed on the beam 1 (this approach can be common to all the embodiments).

 The cover 82 is designed and positioned relative to the support 81 so as to provide a passage for each of the fabrics 51, 53. These passages are provided to allow the deployment / repositioning of the fabrics 51, 53 in substantially opposite directions (approximately 180), as illustrated in FIGS. 9 and 10.

 In addition, the cover 82 is formed and put in place so that the fabric 51 is moved in contact with the cover 82, by means of its end 821 which thus forms a friction zone.

 The support 81 exerts pressure on the winding of fabrics by means of its wing 812, forming support means. This wing 812 is elastically deformable relative to the base 811 of the support 81, so that it remains in abutment on the winding of fabrics despite the variations in diameter of the winding during the deployment / folding back of the fabrics (the wing 812 can thus pass from a position shown in solid lines in FIG. 9 to the position represented in dotted lines in this same figure).

 It will be noted that the cover 82 and the housing 81 can respectively form, furthermore, stops for the draw bars 52 and / or 54. This is in particular possible, for this second bar 54, if the lengths of the fabrics (and therefore the surfaces they must cover) are substantially equal.

 Figure 11 illustrates more precisely the combination of the two

<Desc / Clms Page number 9>

toiles 51 et 53, dans le cas où la toile 53 doit couvrir moins de distance que la toile 51. Dans ce cas, la toile 53 présente un nombre inférieur de tours. La mise en place est alors la suivante : on déroule (111) tout d'abord la toile 51, en agissant sur la barre de tirage 52, ce qui entraîne simultanément en rotation la seconde toile 53. Après 3 tours (par exemple), cette seconde toile 53 sort vers l'arrière (112). Il faut alors la tenir et l'amener (les deux toiles se déroulant simultanément) jusqu'à son point d'accrochage.

cloths 51 and 53, in the case where the cloth 53 must cover less distance than the cloth 51. In this case, the cloth 53 has a lower number of turns. The implementation is then as follows: firstly unrolling (111) the fabric 51, by acting on the draw bar 52, which simultaneously causes the second fabric 53 to rotate. After 3 turns (for example), this second fabric 53 exits rearward (112). It must then be held and brought (the two fabrics taking place simultaneously) to its point of attachment.

It will in fact be noted that hooking means 83 are provided on a part of the vehicle, in this case the door, intended to cooperate with the pulling bars 52, 54 in order to maintain the fabrics 51, 53 in the deployed position.

Similar attachment means can of course be present in each of the embodiments.

Figures 12 to 14 illustrate an advantageous embodiment of the invention. Indeed, using the means which will be described later, a single fabric of the blind can be deployed / folded back not only facing one or the other opening, but also facing the whole. of the two bays.

According to this embodiment, the blind comprises a box consisting of a bottom 91 intended to be fixed on the spar and a cover 92 providing with the bottom 91 two passages for the fabric 51.

The blind conventionally comprises in itself a roller 5 coupled to elastic return means, one end of the fabric being fixed to this roller, the other end of the fabric being provided with a pull bar 52.

According to the invention, the blind also includes means for selective deployment of the fabric, constituted in particular by a second draw bar 55 of particular design.

In fact, this pulling bar 55 has an armature 551 supporting means for deriving the fabric 51. These derivation means are here constituted by an axis, or a rod 552 mounted free in rotation on the armature 551 of the bar print 55.

This rod could also, in another embodiment, be fixed

<Desc / Clms Page number 10>

 as soon as it ensures satisfactory sliding of the fabric. It can also be replaced by two fingers extending towards each other.

 As clearly appears in FIGS. 12 to 14, the fabric 51 forms a loop which passes around the rod 552 of the draw bar 55.

 Note that the housing, and in particular the cover 92, is designed to house, in the folded state of the blind, the rod 552 carried by the pull bar. Thus, when the blind is not used, only the parts used essentially for gripping the pull bars 52, 55 remain visible outside the housing.

 As has been mentioned, such a blind can, with the help of a single roller and a canvas, be deployed in front of one or the other of the two bays, or even in front of all of the two bays, as follows.

 The canvas can be deployed / folded back opposite one of the two bays using the pull bar 52 as shown in Figure 13, the pull bar 55 being left stationary in the vicinity of the housing. The fabric 51 is unwound from the roller 5 through the passage 911 passing around the rod 552.

 The fabric can also be deployed / folded back through passage 912, that is to say facing the other of the two bays, using the draw bar 55 as shown in FIG. 12, the bar 52 being left stationary in the vicinity of the housing. The canvas then forms a loop, the length of which varies between the roller and its end provided with the pulling bar 52.

 The fabric can finally be deployed / folded back facing all of the two bays as shown in Figure 14, by a combination of the two movements mentioned above.

 The blind which has just been described according to the various embodiments of the invention is particularly applicable to the windows separated by a vertical upright as they commonly appear on the rear doors of motor vehicles.

Such a blind can also be applied in particular to vehicle pavilions insofar as a spar would be provided to separate two bays, the spar may be provided to extend in a direction perpendicular to the axis of the

<Desc / Clms Page number 11>

 vehicle, or in a direction parallel to this axis. In the latter case, the pavilion being for example divided into two bays of equal width, it is possible to obscure one or the other of the bays, or both, depending on the direction of the sun.

 It is also possible, in the absence of a side member, to be fixed by the ends of the housing, or even to be joined directly to the window.
