Description

The invention relates to the field of sun visors for vehicles and

especially

for motor vehicles.

  There are several types of sun visors for vehicles which are perfectible in their use, in their efficiency and in their appearance: some are fixed by suction cups, the main disadvantage is that they are for the most part of standard size and do not cover all the area of the glass on which they are glued, others are fixed by pinching them between the door and the bodywork or between the top of the glass and the door frame, they require significant manipulation to put them in place and storage space on board the vehicle to be available; others in the form of blinds fixed to the door or directly to the vehicle, above the door, are weakened by the opening of the door which must be handled with care and are only maneuverable

  manually which on the other hand excludes a remote control.

  Other inventions relating to a vehicle window partly comprise certain means used in the present invention, the essential differences of which are indicated below: - patent for invention US 4,057,094: it has a device comprising a mosquito net which can replace the glass but cannot be used simultaneously which would remove the usefulness of this mosquito net which protects from the entry of insects (column 1, lines 20 to 24); on the other hand the device is only mechanical; in this form a remote control is neither

planned or not possible.

  In a first embodiment which is in no way limitative, with reference to FIG. 1, the device comprises at least one sun visor (3) integrated in the door (1), preferably in the construction of the latter and which can be used at choice of user in place of conventional glass (2) (Throughout this

  description the term "glass" is used for a body of transparent material or

  translucent in glass and / or synthetic material). At least one selection means allows, by rotation producing a transverse displacement which can be exerted either only on the effective part of the sun visor and / or on the window glass or on the assembly formed respectively by the sun visor and its mechanism lifting and / or the window and its lifting mechanism, to put the device in position to be able to raise and lower either the window or the sun visor, when both are in the lowest position, by moving the angle window and / or sun visor so that one or the other is opposite the slide (9) formed by the flexible lips (10) and (11) so as to be able to be actuated

to the top.

  The selection means consists of an electric motor (16), conventional or comprising a piezoelectric device, driving at least a second mechanism comprising at least one toothed wheel (capable of increasing the movement) and a rack in at least one system (15 ) which acts directly or through at least one arm (14) on the rotational movement of the window-sun visor assembly. The arm (14) and the system (15) can be replaced either by at least one eccentric or at least one worm allowing the same displacements actuated electrically thanks to the electric motor (16), or by at least one jack actuated by motor electric, either by at least one cable device (s) driven by drum (s) or by rack (s) driven by electric motor, or by a member comprising a piezoelectric device. This electrically actuated mechanism can be replaced by a mechanism actuated by the variation and / or the controlled pressure difference (s) of a fluid in a receiver, for example a jack.

hydraulic.

  A better configuration, partly because the sun visor assembly thus occupies a smaller value in thickness, is obtained by placing the apex of the angle of rotation of the above assembly as far down as possible or towards the top (the axis (6) can be, in another version, towards the

top of the box).

  To actuate the window or the sun visor vertically, it is possible to use a conventional lifting device such as a linkage mechanism with variable geometry actuated by an electric motor directly or via a toothed sector acting on the window or the sun visor from below and fixed for the inside of the door (relative to the vehicle) on a plate such as (7) or directly on the door. Regarding the fixing of a second lifting device on the outside of the vehicle but inside the door it is necessary to provide a plate support (8) which must be added to the structure of the conventional door in providing for accessibility to fixing means such as screws and nuts. This support of plate (8) has the advantage of bringing a stiffening to the door and if it is extended over the entire width of this door it also brings increased resistance in the event of a side impact. The fixing of the plate on the support (8) can be carried out from the outside of the door in which case it will be necessary to provide a cover such as (17) serving for example to protect the door against scratches. The transverse displacement corresponding to the angular displacement which takes place exclusively in the extreme low position is all the smaller the closer it is to the pivot axis (6). This displacement is compensated by a sliding assembly of each lifting device allowing a displacement of the same magnitude and / or a floating or sliding assembly of the connections between the

  lifting mechanism and the window or the sun visor.

  Another lifting means can be used for the window and / or for the sun visor: an on-board motor such as (12) or (13) associated with a toothed wheel (s) and a rack (s) (s) fixed (s) moves up or down with the window or the sun visor it moves when activated. The rack (s) can / can be at least three types: -classical, straight teeth, preferably arranged vertically, opposite, at the ends of the glass or the sun visor, integral with the door, they are engaged with the gear wheels which, themselves, move with the engine, only when the window or the sun visor is in the position of being extended or retracted; it is partly a safety device to avoid operating the window or the sun visor which is in a position, at the bottom of the door o, which cannot come out because it is not opposite the slide ( 9), it would come up against the top of the box of the door, - with teeth in an arc, two in number, fixed to the door, facing each other laterally on either side of the glass and the screen sun so as to always be in engagement with the gears despite the displacement of these

  in rotation around the axis (6) when choosing the use of the window or the

  Sun. Electrical safety devices, preferably of the end-of-travel and / or thermal circuit breaker type, only allow the window or the sun visor to be actuated if it is in a position to be able to move in translation by the slide (9) and prohibit controls beyond the extreme positions of the window or the sun visor, - a single rack substantially in the central position relative to the window or

  with the sun visor, arranged vertically enough to operate the window or the visor

Sun.

  In a variant of the device, the lifting mechanism actuates the window or the sun visor by means of a notched belt (s) preferably arranged vertically, replacing the rack (s), in which case the motor of the lifting mechanism does not move vertically, it drives in rotation one (s) toothed wheel (s) which actuates (s) the belt (s) kept (s) tensioned (s) by a / crazy pulleys. The window and / or the sun visor is / are fixed (s) to the belt (s) at a point and moves thanks to it (s) up or down when it (s) / are rotated by the motor

electric.

  In another variant of the device, the lifting means for the window and / or for the sun visor is an electric actuator or a cable (s) driven by rack (s) or by driven drum (s) (s) by electric motor or organ

  comprising a piezoelectric device.

  Whatever the variant, whether the electric motor maneuvering the mechanism of the sun visor and / or the window is on-board or not, it can be replaced by at least one member whose useful displacement comes from the variation and / or the controlled pressure difference (s) of a fluid present in this member, for example a hydraulic cylinder or a receiver, providing a torque, actuated

by the circulation of a fluid.

  (4) and (5) symbolize guides also allowing the window or the sun visor to be oriented according to the choice of the user in position or out of position to be lifted. These guides are arranged at the lateral ends of the sun visor and / or of the window from the level of the axis (6) to a height sufficient to ensure positioning by the means (14) - (15) - (16 ) and to ensure good guiding in vertical translation or close to the vertical of the sun visor or of the window when the lateral edges are approximately parallel. In another variant, (4) and (5) are the supports of the system (s) for guiding and / or lifting the window and / or the sun visor, they are arranged at the lateral ends or substantially parallel to the window and / or the sun visor at any distance

lateral ends.

  The command is either to select the sun visor or the window or to go up or down one or the other is electric, safety devices are preferably used to prevent maneuvering up the sun visor or the window when the element that the user wants to control is not aligned with the slide (9) and / or prohibit the operation of the means for selecting the sun visor or the window when the sun visor or the window is in position intermediate or high, engaged in the slide and / or prohibit the operation beyond the extreme positions of the body of the sun visor by electrical devices for example

  type of limit switch or thermal circuit breaker.

  In the variants described below, the elements common with the first embodiment are not described again, unless necessary, but must

  be considered as existing in these variants.

  According to a variant illustrated in FIG. 2, the displacement of the window (18) or of the sun visor (19) inside the box of the door to put them either in position to be lifted , is done in a translational movement indicated by the

  horizontal arrows. At least one guide such as (20) facilitates this translation.

  The different types of lifting and selection means used are identical to those used for the device in FIG. 1 with the difference that any movement along an arc of a circle whose center is the axis (6) for FIG. 1

  is replaced here by a translational movement either for the window and the screen

  sun themselves either for the window, the body of the sun visor and all or part of the lifting means which are adapted to their translational movements if they are

  on board and / or move with the window and / or the body of the sun visor.

  According to a variant illustrated in Figure 3, the window (21) and the lens hood (22) have

  each an independent backstage to be taken out or returned. Glass or screen

  the sun each has its own means of lifting and the movements of one or the other are completely independent, which makes it possible to use either the window or the sun visor or both at the same time; this last possibility is an advantage which makes it possible to associate the properties of (21) and those of (22) compared to the device as it is presented in figure 1 or figure 2 but it requires a more

  large thickness at the top of a door to accommodate the glass and the

sun at the same time.

  According to a variant illustrated in Figure 4, the sun visor (23) is not associated with its own lifting means, to be actuated in up and down movement it is driven either by the movements of the window (24 ) it can be operated alone, independently of the sun visor or by a first mechanism that can operate, at the option of the user, the sun visor or the window. For this, either the sun visor (23) is secured to the window (24), thanks to a second mechanism preferably in their lower part which will remain inside the structure, this securing preferably taking place by mechanical hooking thanks to studs that can move to penetrate corresponding holes in the bottom support of the window and / or the sun visor, or the frame or the fixing used to operate them; in this configuration the use of the sun visor cannot be done directly and in the case where the window is raised, it must be lowered before being able to raise the sun visor thanks to the window but the mechanism is simplified since requires only one lifting device for both uses. It is possible to drive the sun visor by hanging on the top of the glass but this solution shows in the frame the hanging device which can be annoying in use (pinching, hanging clothes), or the sun visor or the window is secured to the unique lifting mechanism (the

first mechanism).

  According to a variant illustrated in Figure 5, the window (25) is fixed or pivotable but does not retract into the box of a door; for an automobile it is the windshield or the window opposite the rear, a tailgate or rear trunk door window, or a front or central or rear side window or a transparent part of the glass roof and / or made of synthetic material. This type of window can be mounted, for example, on a fixed part of the structure of a vehicle, but also on a door. Regarding a windshield, if the body of the sun visor associated with it is opaque or not very transparent, it can represent a danger when the vehicle is traveling at high speed; specific security is added to the operation of this sun visor, for example the controls are only within reach of the driver and / or pressure must be maintained on the control member for the duration of the maneuver otherwise it s '' stops and / or it is necessary to press two organs simultaneously, for example with two fingers, and / or the movement of displacement is relatively slow in order to

  give the driver time to react to an unwanted operation of the windscreen

  Sun. The sun visor (26) has its own operating means allowing

  retract it unlike the glass with which it is associated.

  According to a variant illustrated in FIG. 6, the window (27) only has an outward and retracting movement in the box of the vehicle structure which can also be a door, like a conventional window. sun visor (28) which uses the means of lifting the glass alternately with the glass or which has its own lifting means, the trajectory of which cuts that of the glass, can occupy the place of the glass outside the box when the window is completely lowered and allows free passage. The flexible part (29) can facilitate guiding the sun visor in the upward direction. The sun visor (28) which deforms sufficiently

  by following its non-rectilinear trajectory which is partly that of the window. Visor-

  sun in this variant comprises an active part composed, at least in part, of at least one movable body such as (28), plane or curved, comprising, at least in part, a fully or partially opaque material or a synthetic material, transparent or translucent and / or treated and / or tinted and / or covered with at least one film stopping or reflecting all or part of the light which illuminates the body or transforming this light, or a flexible sheet or canvas which may include a complete frame or partial and / or a frame and / or a

  reticulated reinforcement, or an inscription of an advertisement and / or decoration.

  A second mechanism makes it possible to select the element which will be operated, actuated electrically and / or thanks to the variation and / or the difference in pressure of a fluid in a receiver, makes it possible to secure the first mechanism (lifting mechanism) with the body of the sun visor or with the window, when this first mechanism is unique for the sun visor and for the window and

  activates one or the other of these elements.

  The electrical safety devices of the first version are also applied.

  According to a variant not illustrated, the body of the sun visor consists of at least two elements partially superimposed or juxtaposed in the position of effective use, then forming in useful area the equivalent of the useful area of the window to which it is associated or the area it is intended to cover. This configuration can be useful, for example, when there is insufficient space in the box of the vehicle structure to retract a sun visor in one piece. The elements are taken out of the box or retracted one after the other

  the other or their movement is simultaneous.

  According to a variant not illustrated, the location of a movable vehicle window is associated with a sun visor, the active part of which is composed, at least in part, of at least one movable body comprising, at least in part, a fully or partially opaque material or a synthetic, transparent or translucent material and / or treated and / or tinted and / or covered with at least one film stopping or reflecting all or part of the light which illuminates this body or transforming this light, or a flexible sheet or canvas which may include a complete or partial frame and / or a frame and / or a cross-linked reinforcement or an inscription for an advertisement and / or a decoration, which can be positioned either in a juxtaposed or adjacent location the location of the glass in the effective use position, in whole or in part, in place of the glass in the effective use position when the glass is in the retracted position in a box

  of the structure of the vehicle, this structure possibly also being a door.

  The sun visor is an integral part of the vehicle, its body can be retracted into a box of the vehicle structure, rolled up like a blind, the

  structure can also be a door.

  The operating and / or selection mechanisms are identical to those of the first embodiment or to those of the variants described above with the exception of the variant illustrated in FIG. 6 but here the body of the sun visor is actuated by being pulled, to be unrolled, in its free part, its part

  opposite being linked to a winding axis.

  To retract it, roll it up, the effective part of the body is retracted into the box. The body of the sun visor preferably comprises in its effective part a rigid part situated from one end to the other of the body horizontally or approximately. The maneuvering mechanism is linked to this rigid part, preferably by means of two arms arranged on either side of the body, preferably sliding in whole or in part in side rails, those of the window usable by the body when in the retracted position, or separate rails reserved for the sun visor. These two arms can replace or add at least one of the means described below (page 15, line 38 to page 17, line 01) When the body of the sun visor, in the position of effective or intermediate use, is retracted by the operating mechanism, the body is wound on the winding axis which is permanently maintained under the effect of a torque, in the

  winding direction, produced by at least one spring.

  Electrical safety devices are identical to those described in the first

embodiment.

  According to a variant illustrated by FIGS. 7,8,9,10,11 and 12, at the location of a fixed or movable window of a vehicle and in particular of a motor vehicle is associated a sun visor such as for example (46) or (47) or (48) the active part of which is composed, at least in part, of at least one movable body comprising, at least in part, a fully or partially opaque material or a synthetic, transparent or translucent material and / or treated and / or tinted and / or covered with at least one film stopping or reflecting all or part of the light which illuminates this body or transforming this light, or a flexible sheet or canvas which may include a complete or partial frame and / or a frame and / or a cross-linked reinforcement or an inscription of an advertisement and / or a decoration, which can be positioned either in a location such as for example in (30) juxtaposed or close to the location of the window in position d effective use either in whole or in part at the place of the glass, when it is retractable, in the position of effective use such as for example in (31) either in whole or in part in place of the glass, when it is retractable, with the means for guiding the window when the window is in the retracted position in a box of the vehicle structure, this structure being able to be a door, the replacement of the window by the body of the sun visor being able to be done in these last two cases, only on the trajectory of the window outside the box or extend over part of the path of the window inside the box. If the

  trajectories intersect inside the box as in (32) there is no overshoot

  visible thickness, if they intersect on the outside as in (33) it is necessary to provide for the tightness of the box at the level of the enlarged slide or of a second

  slides according to the location of the trajectories.

  The sun visor is an integral part of the vehicle, the body, its active part being placed, at the option of the user, in the position of effective use or in an intermediate position or in a retracted position in a box of the structure of the vehicle, rolled up like a blind, the structure being,

also, a door.

  The sun visor can be operated by a mechanism driven either by an electric motor or by a receiver, the useful torque of which comes from the variation and / or the controlled pressure difference of a fluid present in this receiver which can be, for example , a hydraulic receiver activated by traffic

of a fluid.

  Whether the mechanism is driven by an electric motor or by a receiver which can be hydraulic, the operation control by the user is electric, that is to say, for example, by switches or push buttons directly controlling the organs or via relays and / or at least one electronic variator or amplifier and / or solenoid valves. The mechanism, when controlled by the user, rotates the lower part of the body of the sun visor, directly or by means of slides such as for example (34) or (35) or (36), in a store of suitable shape such as for example (37) which allows, at the user's choice, to unwind the body of the sun visor, if necessary with significant effort without the curvatures of the body becoming folds but in upward movement ,

  the lowering movement being easier by winding around the axis (38).

  The motor or the receiver is located either inside the roller formed by the body of the sun visor wound on itself around the axis (38) driving the body directly or via a reduction gear, or the outside of this roller, the drive being done by at least one connection preferably at the end

axis.

  Guides arranged longitudinally, in opposition on either side of the body of the sun visor, at the lateral ends, are arranged either juxtaposed or next to each other such as for example (39) second guides such as for example (40) which are the guides of the window (45) or as for example (41) by partially superimposing the trajectory of the glass and the trajectory of the body of the sun visor. In an other

  configuration the glass guides also serve as guides for the body of the

  sun, providing an appropriate shape if necessary to laterally retain the

  body of the sun visor if it is not rigid enough and may escape from the guides.

  Whatever the configuration, the rectilinear or slightly curved sections of the guides of the body of the sun visor for example (42) can be extended by curved guides, wound in spirals for example (43), arranged in opposition in the store of the visor -sun to guide the body more effectively, sliders included, over all or part of its length. The slide drive in rotation takes into account the variable distance of the slides

  to the axis (38) of winding the body of the sun visor.

  The slides arranged at the lateral ends of the body of the sun visor can be trapped in their guides in which they can slide in

  exit and retraction movements.

  The slides form part of the body of the sun visor or are integral therewith, preferably, reinforcements such as (44) at the junction (49) of these two parts for

  avoid shearing at this junction with the slides after long use.

  The junction (49) is shown hollow in Figure (8) but it can also be of uniform thickness with at least one of the adjacent parts or in relief. The sliders, which are preferably in one piece from one end to the other of the body of the sun visor, can be bent but have insufficient flexibility and transmit movements to the whole body of the sun visor.

  printed on them when the thickness and / or stiffness of the body of the barrier

  the sun is (are) not sufficient for it to extract itself during a

exit maneuver.

  When the body of the sun visor is at the end of the interior or exterior travel and / or when the trajectories of the window and the body of the sun visor intersect, electrical safety devices prohibit maneuvering beyond the extreme position and / or maneuvering the window when the body of the sun visor is in its path and / or to maneuver the body of the sun visor when the window is in

its trajectory.
