Description

 The present invention relates to a removable connector qour hydraulic circuit connection pipe, in particular for a hydraulic remote control device of at least one controlled, adjustable and / or lockable member, mounted on a support, such as a rear view mirror, in particular an exterior mirror for a motor vehicle, the orientation of which is to be adjusted from the driver's seat inside the vehicle, the remote hydraulic control device according to the invention also being usable for adjusting the position of other members to position by pivoting in particular around two axes perpendicular to one another.

 Such a device is described in the European patent application published under No. 0.152.219, and in which the very significant advantages provided by such a device have been presented compared to the prior embodiments of the state of the art, comprising transmissions by levers, linkage or wheelhouse, movement transmissions by cables, or even electric motors. These advantages are quickly mentioned below.

 In the various embodiments of the hydraulic control device which are described in the aforementioned European patent application, the manually actuated control member is always a handle or a handle of a manipulator which is pivotally or articulated on the cover. a housing containing the flexible-walled chambers of the positioning transmitters. The handle or the handle of the manipulator is always mechanically connected to at least one rigid member, also mounted inside the case, so that the pivoting movements given by the user to the handle or to the handle of the manipulator are transmitted, with or without reduction in the transmission, at least one of these internal rigid members which comes or comes to compress at least one deformable pocket with flexible wall of the positioning transmitters.

 The hydraulic remote control device which is the subject of the aforementioned European patent application & in particular for the disadvantages that the assembly of the manipulator and the positioning transmitters is an expensive assembly, on the one hand because of the large number of parts which constitutes it, and on the other hand the fact that these parts are difficult to assemble. In addition, in all the exemplary embodiments, the handle or the handle of the manipulator is presented as a lever projecting towards the interior of the cabin of the vehicle with respect to the dashboard, which is detrimental from the safety point of view. of people transported, and what does not necessarily adapt to the style provided for the driving position and the dashboard or dashboard.Moreover, if the installation of hydraulic devices has the same advantages as that of the wires supply of electric motors, if we consider the path between the driving position and the exterior mirrors to be controlled, the fact remains that the hydraulic devices have the specific disadvantage that in the event of a pocket rupture deformable, a mirror or a connecting pipe, all of the corresponding hydraulic circuits must be dismantled and replaced, and it is for this reason that it has already been proposed to equip the device described in s the aforementioned European patent application for a hydraulic connector for each hydraulic control circuit, this hydraulic connector comprising two variable volume chambers, one of which is constantly in communication with the deformable pocket of the corresponding positioning transmitter, while that the other is constantly in communication with the variable volume chamber of the corresponding positioning receiver, the two variable volume chambers of the connector being held by mechanical means in the pressure transfer configuration from one another.

 By the present invention, it is proposed to remedy the various drawbacks attached to the hydraulic control device described in the aforementioned European patent application, and to bring in particular improvements to the hydraulic connectors of this d2sposltlf ..

 Of course, the remote control of a controlled member such as an exterior mirror located, on a vehicle, on the passenger side, should be possible, under the same conditions, from the driving position and for a low cost and all of the the device will advantageously be partially removable, due to the presence of hydraulic connectors, in the event that it is necessary to replace a member such as a positioning transmitter or receiver.

 The principle underlying the device according to the invention consists in directly using deformable pockets of hydraulic fluid, not only in the positioning transmitters, but preferably also in the positioning receivers, so that a certain volume of hydraulic fluid is transferred from the transmitter to the corresponding receiver of a hydraulic circuit, as required. Deformable pockets with flexible walls can occupy practically any position in space, and in particular three of them can be arranged in circumferential directions, each at a central angle of about 1200, or occupy positions 1200 to each other, to allow control of the orientation of adjustable members such as vehicle mirrors. The use of deformable flexible wall pockets in the transmitters also allows, to some extent, s 'free from contingencies of shapes at the level of variable volume chambers delimited by these pockets. However, it remains necessary to maintain or dress these pockets of positioning transmitter in supports which can take any shape imposed by the style, and which can therefore simultaneously act as hubcaps, whether these supports are made up of fixed parts. or mobile, and without any mechanical component, such as a piston, a jack, etc.

does not come between any moving part for holding a positioning transmitter pocket and said pocket itself.

 Another principle which can simultaneously be implemented consists, according to the present invention, and in order to use practically the entire volume of hydraulic fluid available in each hydraulic circuit, to use cams associated with the manually actuated control member so to expel, by compression, practically the entire volume of fluid initially contained in the deformable pocket of the corresponding transmitter. Similarly, cams can be provided to stress the deformable pockets of the positioning receivers, so that only the internal volume of the connection pipes can be considered as a dead volume. In this case, a third principle can advantageously be implemented in the device according to the invention, namely particular arrangements of deformable pockets overlapping for example and combining their effects with particular shapes given to the cams in order to obtain particular effects, such as the sequential transmission of an unlocking or unlocking order, followed by at least one positioning order, in response to an operation of the manually actuated control member.

 In addition, in different possible applications of the device according to the invention, locks or blockages of controlled members may be necessary.

In these different cases, the locking or blocking function will advantageously be fulfilled without the deformable pockets being put under high pressure.

 Although, in all cases, the volume of the deformable pockets is linked to the function which it is desired to have these pockets perform, it should be noted that the control & distance device according to the present invention is limited, in its applications, to the control of all the controlled components which require only adjustments ensured over short strokes, as is the case of mirrors or headlamps, as well as to certain components requiring interlocks, such as the headlamps and sunroof of a vehicle, or still the vehicle doors, which we want to be able to lock from the inside.

 Finally, another principle implemented in the device according to the invention will consist, in order to limit the number of manually operated control members or, for a given number of these, to increase the number of controlled members, to be provided channel switching for the hydraulic fluid flowing from a deformable pocket of a transmitter to one or the other of several variable volume chambers of receiver associated with this transmitter.

 To achieve the aim presented above and in order to connect connection pipes, which, if they were each made in one piece, would be too long and too difficult to install, the invention plans to use, as already proposed in the above-referenced European patent application, at least one removable connector in each of the hydraulic circuits of the device. In this case, each removable connector comprises a deformable pocket receiving connections, connected by a connecting pipe to the deformable pocket of a corresponding transmitter, and the connector also comprises a deformable pocket transmitting connection, connected by a connecting pipe to a deformable pocket of the corresponding receiver, the connector finally comprising an envelope housing the pockets transmitting and receiving connections by keeping them in abutment l one against the other so that the pressure exerted on the connection receiving pocket is tra nsmise b the transmitting connection pocket. According to the invention, it is then advantageous for the casings of the removable connectors to be constituted by a single connector body with two flaps which can be folded down and fixed one against the other, in a removable manner. , and therefore each has an equal number of at least two, but preferably at least three imprints each coming opposite an imprint of the other flap when the two flaps are folded down and fixed one against the other, and the emitting pockets of the -connections being each arranged in one of a corresponding number of imprints of a flap which come opposite the imprints of the other flap in each of which is arranged one of the receiving pockets of connection.

 In an embodiment of advantageously simple structure, the connector body is molded in one piece from a plastic material and its two cavity flaps are connected to each other by at least one flexible hinge and are fixed removable one against the other by elastic snap-fastening.

When the control device according to the invention comprises both a channel-switching manipulator and removable connectors housed in a single connector body, it is advantageous for one of the two flaps of the connector body to have two sets of footprints each including
(1) at least three fingerprints in which three connection receiving pockets are housed, for the transmission of any control pressure to one of the two controlled members, and
(2) at least three fingerprints in which three deformable isolation pockets are housed, each in communication respectively with one of the three receiving receptacles for connection of the corresponding assembly, the receiving receptacles for connections of the two assemblies being either transmitted to the connection transmitter pocket. According to the invention it is therefore advantageous that the envelopes of the removable connectors are constituted by a single connector body with two flaps which fold back and are fixed against one another, in a removable manner, and each of which has an equal number of at least two, but preferably at least three imprints each coming opposite an imprint of the other flap when the two flaps are folded down and fixed one against the other, and the emitter pockets of the connections being arranged each in one of a corresponding number of imprints of a shutter which come opposite the imprints of the other shutter in each of which is arranged one of the connection receiving pockets.

 In an embodiment of advantageously simple structure, the connector body is molded in one piece from a plastic material and its two fingerprint flaps are connected to each other by at least one flexible hinge and are fixed removable one against the other by elastic snap-fastening.

When the control device according to the invention comprises both a channel switching manipulator and removable connectors housed in a single connector body, it is advantageous for one of the two flaps of the connector body to have two sets of fingerprints each including:
(1) at least three fingerprints in which three connection receiving pockets are housed, for the transmission of any control pressure one of the two controlled members, and
(2) at least three indentations in which three deformable isolation pockets are housed, each in communication with one of the three connection receiving pockets of the corresponding set, the connection receiving pockets of the two sets being connected in three independent pairs each comprising a connection receiving pocket of one set in communication with a connection receiving pocket of the other set by means of their isolation pockets which are connected to each other by a coupling, into which a connecting pipe opens to one of the three transmitting pockets for positioning the channel-switching manipulator, and the other flap of the connector body also has two sets of imprints each comprising
(l) at least three fingerprints in which three pockets emitting connections are housed, for the transmission of any control pressure to one of the two controlled members, and each of which is connected by a connecting pipe to one of the three respectively receptor pockets for positioning the corresponding controlled member, and
(2) at least one imprint in which is housed at least one deformable pocket receiving shutter, connected by a transmission pipe to one of the two pockets emitting shutter of the manipulator switching channels, so that when the two flaps are folded down and fixed against one another, each of the three connection receiving pockets corresponding to a controlled member is in the pressure transmission position with one of the three respectively, transmitting connection pockets corresponding to the same member controlled, and the closure receptacle pocket (s) associated with the three transmitting connection pockets corresponding to this same controlled member is or are in the pressure transmission position with the three isolation pockets in communication with the three corresponding connection reception pockets to the same organ ordered.

 It will be noted that the presence, in the control device, of connectors makes it possible to divide each hydraulic circuit cooked into two independent parts in terms of the hydraulic fluid. Consequently, if a hydraulic circuit has a fault, on the side of its transmitter or on the side of its receiver, only one of the two sub-assemblies is to be replaced, and it is not necessary to drain the hydraulic fluid from the whole of this circuit. Advantageously, for this purpose, in order to facilitate repair and maintenance operations at the level of the connector, at least one of the two flaps of the body of the latter is in two removable parts independently of one another with respect to the other flap, and each of the parts has one of the two sets of footprints of the corresponding flap. In this case, if the two controlled organs are a left and a right mirror respectively, by lifting one of the flaps, you can access the pockets relating to one of the mirrors by protecting the pockets relating to the other mirror (9th any untimely action.

 In FIGS. 1a and 1b, a nanually actuated control member, or manipulator, of the fixed button-manipulator type, has been shown for a remote hydraulic control device of a controlled member, which is, in the following of the present description, a movable exterior mirror of a motor vehicle. The hydraulic remote control device for positioning the mirror includes three hydraulic positioning circuits, each of which comprises a positioning transmitter, consisting of a deformable transmitter pocket with flexible wall, in a dobby synthetic rubbery, and it is in communication by a flexible tube of small diameter and relatively little elastically deformable, with a similar pocket, deformable and with flexible wall, constituting a positioning receiver. The set of two transmitter and receiver pockets and the connecting tube is filled with a certain volume of hydraulic fluid, so that if we compress the pocket of the era head, its volume is reduced and the hydraulic fluid which it contains is transferred under pressure by the connecting tube into the receiver pocket, which increases in volume. Your position receiving rocks are retained between the adjustable rear view mirror and a support, which '' they mechanically connect, and to which support the mirror is attached by means of ball joint, as described with reference to Figure 4 of European patent application 0152219 to which reference will advantageously be made for more details on the mounting structure of the adjustable rear view mirror in its support box, it follows that an increase in volume of one of the receptor pockets for positioning causes the mirror to pivot relative to its support case, which causes compression of the '' at least one other of the positioning receptor pockets which are distributed around the pivot center of the mirror on its support, so that fluid hydraulic is transferred under pressure from this or these compressed positioning receiving pockets to the transmitting positioning pocket (s) which is or are connected to it by a communication tube.

 The button-manipulator of FIGS. 1a and 1b comprises a casing of generally cylindrical exterior shape, consisting of a tubular side wall 1 closed at one end by a cover 2, and surrounding an internal tri-lobed body 3 projecting from ur. th face.

 a bottom 4 in the form of a flat disc, the other surface of which carries, projecting, lugs 5 of elastic snap-fastening in holes r. arranged for this purpose in a support 6, such as the dashboard or the dashboard. By the end of its side wall 1 on the side opposite to the cover 2, the casing is fixed by gluing, ultrasonic welding or in any other suitable manner, possibly removable, at the periphery of the opposite face from the bottom 4.

The casing, whose side wall l. And the cover 2 are in one piece, for example of a relative plastic material-i.ent rigid, is thus secured to another rigid orca a, also made of plastic, constituted cu bottom 3 and internal body 4, come in one piece. The assembly is attached in a fixed position by snap-fastening on the support 6. Each of the three radial arms 7 of the internal body 3 defines, with the other two, concave cells forming, with the facing parts of the cover 2 and of the side wall 1, three housings each opening towards the outside of the button through an opening 8, partly formed in the side wall 1 and partly in the cover 2. In each of the three housings regularly distributed at 1200 from each other around the center of the manipulator button is housed a transmitter transmitting pocket 9 which is a deformable pocket thus isolated from the other pockets by the arms 7, and, the tube 9a dc of connection to the corresponding positioning receiver passes through facing holes made in the bottom 4 and in the support 6. Each deformable pocket thus protected in a rigid envelope is accessible from the outside, through the corresponding opening 8, and it suffices for the user to press say ctement on the accessible part of the flexible wall of the pocket 9 to compress it in its housing and transmit a hydraulic command command of posi actuation to the corresponding receiver. Simultaneous support on two pockets 9 is possible and easy, from the front and / or laterally, due to the shape and extent of the openings â as well as the regular distribution of the pockets 9, openings 3 and arms 7 to 120 'from one another and in circumferential wax around the center of the button. This manipulator has the additional advantages that it is constituted by the bonding of two rigid pieces alone, each of which has strong siples and is easy to manufacture. On the other hand, the thickness of the manipulator button is that is to say its dimension perpendicular to the support 6, is small and its external drills can be adapted to the style of the table on this edge, since the casing may have a polygonal section for example.

 The manipulator shown in FIGS. 2a and 2b is also a fixed manipulator button with direct contact on the deformable pockets, and which has many characteristics of structure identical or analogous to those of that described above. The essential differences are that the three openings 18 for access to the three deformable pockets 19 are oval openings formed only by the side wall 11, between the cover 12 and the bottom 14, and that the internal body 13 is simply made up of three radial arms 17 each in the form of a thin but nevertheless stiff veil, extending from the center to the internal surface of the side wall 11. The means for retaining the manipulator button on the support 16 have not been shown, but, as in the previous example, the tubes 19a of the pockets 19 pass through facing holes made in the bottom 14 and in the support 16.

 On the contrary, on the fixed and direct contact button-manipulator of FIGS. 3a and 3b, the general structure and essential components of which are the same as in the two previously described examples, the openings 28 for access to the deformable transmitting pockets 29 are circular openings formed only in the cover 22 which the side wall 21 hooks up without opening.

 bottom 24 fixed on the support 25. In addition, in this example, the radial arms 27 of the central body 23 do not extend to the internal face that the side wall 21, but remain however large enough to isolate the ochres 29 each other.

The examples of this buttons-ranipulators of Figures 2a, 2b, and 3a, 3b, on which the controls are provided by respectively radial and axial actuations on the plugs accessible by the openings, have the new advantages as the example of the figures la and lb and can also be operated with the fingertips by the user, and with good selectivity of the commands
When the controlled member is a safety member, oriented and / or locked in a position which must not be accidentally or inadvertently changed, by inadvertent compression of a deformable transmitter pocket, the button-manipulator used is preferably a variant of that of Figures 3a and 3b and such as that shown in Figures 4a and 4b. On these, the lateral surface 31 is that of a cover 32 in the form of a relatively thick disc and constituting a protective casing having, in its face facing the support or dashboard .36, a central recess in which is engaged and fixed a rounded core 33 integral with the end of a rigid central rod 35 projecting from a base 34 for fixing the button-manipulator on the support 36. In its face turned towards the base 34 and space of the latter Finally, the casing 32 also has three regular cells distributed around the central recess for connection to the core 33, and in each of which is housed a deformable emitting pocket 39, part of which is directly accessible from the outside by an opening. circular formed in an annular plate 37 fixed around the core 33 and retaining each pocket 39 in its recess.

In this example, the connecting tubes of the pockets 39 pas-.

feels in channels formed in the central rod 35 and the core 33, and opening into the for.d of the cells will house pockets 39. The control is therefore done by "below", by inserting the tip of these fingers between the plate 36 and casing 32 and compressing at least one pocket 39 towards the bottom of its cell through the corresponding opening in plate 37.

 In this example, it is also possible for the pockets 39 to be housed in a hollow casing and separated from each other by radial arms connecting the casing to the central core 33.

 In all variants, the deformable transmitting pockets are housed in a rigid envelope, in the form of an inverted bowl and with a closed bottom, in which the pockets are retained around a central rod integral with the bowl and connecting it to the base of fixing to the support.

 In FIGS. 5a to 5c, another example of a manipulator with direct contact on the transmitting pockets has been shown, but this manipulator is no longer of the type fixed on its support, but retractable in the latter. This support 46 is. as in the previous examples, the dashboard in which is formed a circular orifice surrounded by a flange 46a in excess thickness towards the inside of the dashboard, and in which is housed a mechanism, for locking, for example with ball, schematized at 46b, intended to immobilize the manipulator in the extended position and also in the retracted position relative to the support 46. This manipulator comprises a tubular casing with a substantially cylindrical side wall 41, which is open at one axial end and completely closed at the other end axial by a cover 42, the peripheral part of which is connected to the side wall 41 by an extra thickness forming a shoulder 42a coming into abutment against the external periphery of the opening of the support 46, in order to limit the insertion of the manipulator into rest position, retracted or retracted, in the support 46 (see FIG. 5b). The manipulator also comprises an internal body (43) provided with three arms (47) extending both radially 120 from one another and axially, and secured by the end of the side opposite to the cover 42 of a bottom 44 in the form of a circular disc. In each of the three cells delimited between the arms 47 of the internal body 43 is housed a deformable transmitting pocket 49, the tube 49a of connection to the corresponding receiving pocket passes through a hole in the bottom 44. The internal body 43 and the three pockets 49 housed in their cell are surrounded by a flexible sheath 45, produced in a sleeve of a thin and elastic film, which facilitates mounting and improves the aesthetic appearance of the pockets 49, so that the assembly consisting of the bottom 44, the body 43 and the pockets 49 can be easily inserted in the casing, until the bottom 44 abuts against the end of the side wall 41, which has three openings 48 regularly distributed in the direction circumferential, and centered at 1200 from each other and each of which constitutes an access opening to a cell for directly compressing the pocket 49 therein. After securing the side wall 42 on the front 44, the manipulator is ready to operate. By firing from the rest position, in which the manipulator is retracted or retracted into the support 46, as shown in FIG. 5b, when the user wants to transmit a command order, he grasps the manipulator by its cover 42 and pulls it axially towards the outside of the support 46, until the bottom 44 comes into abutment against the rim 4.6a, and the locking mechanism 46b then blocks the manipulator in the extended or service position. In this position, it then suffices for the user to compress with his finger at least one of the pockets. 49 by the corresponding opening 48. After issuing the desired command or commands, the user pushes the manipulator into the retracted position, in which it is again blocked by the locking mechanism 46b.

 The manipulator of this example can have many different drills, in particular in cross section, the latter being for example polygonal. The casing 1 42 and the internal body 13 only serve to support the pockets 49, each of which may be of a volume of 1.1 cm 3 for example, and filled before or after assembly, which allows a good adaptation of the manipulator board style.

 In FIGS. 6a and 6b, a manipulator with indirect contact of a so-called "linear" type has been represented, comprising three push-buttons 50 arranged side by side, and each of which comprises a push-button or rocker 5l in fore of substantially rectangular tongue, the lower part 52 of which projects from the side of its external face and bends from the side of its internal face, forming a groove 53 closed on each side by two thin veils, the sides 54 extending up to the end of the upper part 55 of the tongue, which is folded over on the side of the internal face. By its curved upper part 55, the Doussoir is pivotally mounted, around a transverse axis 56 which crosses this part 55 and is common to the three pushers 51, on a common base 57 for fixing to the support 58, such as the dashboard. The base 57 has, opposite each pusher 51, a recess or a cell in which is housed a deformable transmitting pocket 59 retained in the lower part by a stop 57a carried by the base 57 and limiting the corresponding cell, while the corresponding connection tube 59a passes through a hole drilled in the base 57, in the vicinity of the upper part of the corresponding pocket 59. By pressing on a pusher 51, it is pivoted about the axis 56, towards the base 57, and the compression of the corresponding pocket 59, the stop 57a then being housed in the groove 53 to allow maximum compression of the pocket 59.

In this example too, the push button is independent of its lonctior.re-ent and can be adapted to the style of the dashboard. The manipulator can include more than three push buttons, each provided with a single pocket deformable, and one of which may be a pocket for unlocking or clutching, in communication with a pocket for receiving unlocking or clutching which, when inflated following compression of the poc: -. e corresponding emitter, above or at least very significantly reduces the friction between two contact surfaces which, by mutual friction keep the mirror in a particular position.

This unlocking command precedes the pivoting commands which are thereby facilitated, as is more fully described below with reference to FIGS. 16a to 18c.

 FIGS. 7a and 7b show a second example of a linear manipulator with indirect contact, comprising two double push-buttons 60 (and not three single push-buttons 50 as in the previous example).

Each push-button 60 comprises a push-button 61 in the form of a rectangular tongue, the lower part 62 of which is thickened and projecting from the side of its external face, the central part 63 is thickened and projecting from the side of its internal face, and the part upper 65 curved on the side of its internal face, and these three parts are connected to each other by two thin lateral webs 64, of triangular shape, the largest dimension of which is in the perpendicular direction. at the external face of the tongue 61, is at the level of the central part 63, in an area crossed by a transverse axis 66, common to the two push buttons 60, and around which each push button 61 is thus tilted. Axis 66 is support.

by a base 67 for fixing to the dashboard 68 by any suitable known means, for example by screwing, snap-fastening, bonding, etc., the base being common to the two push-buttons 60. This base 67 has, for each button- pusher 60, two recesses or cells, each of which is respectively facing one of the two corresponding halves of the pusher 61, on either side of the axis 66, and in each of these two recesses is housed one deformable transmitter pocket 69, the connecting tube 69a of which passes through a hole drilled in the bottom of the hollow and corresponding and through the base 67. Thus, that the pusher 61 is rocked in one or the other direction around the axis 66, it compresses a pocket 69 to send a command order to the corresponding receiver. The two pockets 69, arranged between each pusher 61 and the common base 67 can be of the same volume or of different volumes. The assembly formed by the base 67 and the pushers 61 constitutes a rigid envelope protecting each pocket 69. In this example, four functions can be performed with the two double pushbuttons 60, which makes it possible to reduce the space required for manipulated-.

control unit for the mirror, and to group an additional function, for example a clutch or unlocking command, with the three mirror positioning commands. Of course, this mechanism can be generalized to more than two push buttons 60 arranged side by side and each fulfilling two functions, because it is equipped with two deformable pockets, and the shape of the manipulator can be adapted to the style. of the dashboard.

 In FIGS. 8a and 8b, there is shown an example of an oscillating manipulator 70, which comprises an oscillating pusher 71 having a head 72 by which it is enca ge and guided in its pivoting in a tubular body 73 with a closed bottom 74 having a central boss 75 substantially hemispherical, projecting towards the inside of the body 73 and engages in a hemispherical recess formed in the end of the head 72, in order to constitute a ball joint of push button 71 in the body 73. The latter ensures the mounting the manipulator 70 on a support 76, such as the dashboard, while being retained in an orifice in the support 76. The oscillating plunger 71 also includes a thrust place 77, outside the tubular body 73 and which is shaped , in its peripheral part, both in abutment projecting outwards (that is to say towards the user) to limit the sliding of the finger of the user when actuating: tent, and in slim skirt projecting i ntérieur (towards the body 73 and the support 76) to protect the manipulator against the penetration of foreign bodies towards the three deformable pockets 79 housed in a recess formed in the tutubular body 73, between the internal face of its lateral wall on the sound side open end and the external face of a thinned part at the neck 78 which connects the head 72 to the push plate 77. The pockets 79, each of which has a volume of 2 or 3 cm 3 for example, are distributed regularly in circumferential direction around of the neck 78, and each pocket 79 extends for example in an arc of a circle subtended by an angle. center of 1200. The head 72 guided by swiveling at 75 on the bottom 74 of the body 73, is externally shaped (see FIG. 8b) in deformation cam with three iobes 72a of compression of the pockets 79, when an eccentric thrust is exerted from the outside on the oscillating pusher 71. In this example, the connection tubes 79a of the pockets 79 pass between the head 72 and the body 73 and leave the latter by holes drilled in its bottom 74. This manipulator therefore only includes two rigid parts, namely the pusher 71 and the tubular body 73, and the three deformable pockets 79, and, as there is always at least one pocket which is at least partially filled, when the device has been mounted, the pusher oscillating 71 is non-removable and is retained in the tubular body 73 by at least one pocket, from this; the manipulator is in place.

 As in the previous examples, the pocket volume is chosen according to the movements provided for the ordered member. The shape of the interior tri-lobed cam of the head 72 makes it possible not only to empty the pockets 79 and to use all the liquid that at least one of them contains, but also to privilege the movements along certain axes, when each lobe 72a is in front of a pocket 79, or to move the body cor..ar.cé, for exer..ple the mirror, along two axes At the same time, when the lobes 72a of the head partially support and simultaneously on two pockets "79.

 FIG. 9 shows a second example of a manipulator with an oscillating plunger guided by rolling in a tubular body and with a compression cam for deformable pockets housed in the body. However, in this second example, the tubular body 83, by which the manipulator 80 is as in the first example, rises in an orifice in the support 86, presents a portion of its central passage which is arranged in sliding bearing in a concave spherical cap which cooperates with a sliding surface in a convex spherical cap, of complementary curvature, presented by the external lateral surface of a tubular skirt 82 which simultaneously constitutes the cae of the push-button 81. This latter comprises, in addition to the tubular skirt 82 which is engaged in the tubular body 83, a thrust plate 87, outside the body 83 and on the side of the center of curvature of the concave surface of the body 83. On the opposite side to the thrust plate 87, the body 83 is closed by a bottom 84, the central part of which supports a stud 85, in the shape of a bulb, which protrudes towards the inside of the body 83 and engaged with a significant radial clearance in the skirt 32. In this way, the internal surface skirt 82 and the outer surface of the central stud 85 delimiting between them an annular recess in which are housed three deformable transmitting pockets 89, regularly distributed around the stud 85 in circumferential direction, and whose cracu extends substantially in an arc subtended by an angle at the center of 1200. The connecting tubes (not shown) of the transmitter pockets 89 to the receivers this corresponding position pass between the skirt 82 and the central stud 85, and pass through holes made in the bottom 81 Thus, any eccentric support exerted by the user on the coughing plate 87 of the oscillating plunger 81, causes a movement of the ball joint the latter in the body.

83 by the skirt 82 which compresses at least one pocket 89 against the central stud 85, which controls the transfer of a volume of hydraulic fluid under pressure to the corresponding positioning receiver (s) of the mirror.

 As in the previous example, the volume of each pocket 89 may be of the order of 2 or 3 cm 3, and be adapted to the necessary positioning strokes of the mirror, and no locking in position of the oscillating plunger is ensured. In addition, the external forehead of the manipulator can be adapted to the style of the dashboard and finally the manipulator cannot be removed after fitting its elements and filling the pockets 89. On the other hand, in the example of FIG. 9, the filling of the pockets 89 with hydraulic fluid must take place after installation and the mechanism comprises three rigid parts 9, namely the oscillating push-button 81, the body 83 and the bottom 84 with its stud 85, this bottom 84 relating to the body 83, while in the example of FIGS. 8a and 8b, the mechanism comprises only two rigid parts, and the filling of the pockets can be carried out before or after assembly.

In FIGS. 10a to 10c, an example of a "floating" pusher manipulator has been shown, since the body with a substantially flat pusher, shown in plan in FIG. 10b, and mounted movable on the one hand a-cc un jg li ::. ity parallel to its plane ot, on the other hand, over a useful stroke perpendicular to its plane, with respect to a base shown in plan in FIG. 10a.
This manipulator 90, shown in cross section in FIG. 10c, comprises a base 91, by which the manipulator is fixed to the dashboard (not shown), and which has the shape of a rectangular bowl With a substantially flat bottom surrounded by a rim of relatively small thickness 92. Three recesses are formed in the upper or internal face of the bottom of the base 91, and each partially accommodates one of the three deformable emitter pockets of the manipulator, one of which is a pcche 93 central and lower (in Figure 10a) and the other two side pockets 94 and 95, substantially in the form of a concave CA facing one another, and yes partially overlap each other by a end portion 94a of the pocket 94 which is arranged above an end portion 9Sa of the pocket 95, the covering being provided in the central part of the base 92, on the side opposite to the pocket 93 , while the three connecting tubes 96, each connecting one e pockets at the corresponding positioning receiver pass through holes in the central part or bottom of the base 92, in the zone delimited between the three pockets 93, 94 and 95, each of which is retained in its recess having , in plan, the shape of a corresponding imprint. The pusher 97 is shaped as a rectangular cover, of dimensions slightly larger than those of the base 91, and flat on its external face and it has on its periphery a rim 98 projecting from the side of its internal face and in the lower end has, projecting towards the inside of the cover 97, a peripheral bead 99 by which it is resiliently snapped onto the periphery of the base 91, so that the cover can move relative to the latter in a direction making it possible to compress these 93, 94 and 95, enclosed between the base 91 and the pusher 97, and also with a slight clearance in the plane perpendicular to this direction. pockets selectively, the pusher 97 has, projecting on its underside, four these cont one, not visible in the section of Figure 10c is directly plumb above the pocket 93, and whose three others, visible in section in FIG. lec, are a side cae 100 of substantially triangular cross section, perpendicular to the side portion of the pocket 94, a side cae 101, of trapezoidal section with small base facing downwards, directly above the side portion of the pocket 95, and a central cam 102, also of trapezoidal section, directly above the superimposed portions 94a and 95a of the two pockets 94 and 95. This central care 102 is the thickest. and of a thickness such that at rest, in the absence of support on the pusher 97, the cam 102 is flush with the pocket portion 94a.

The shapes of the cams 100, 101 and 102 and of the cam not shown are such that they make it possible to use all the volume of hydraulic fluid necessary for the deflections of the mirror in cooperation with the pockets, the volumes of which can vary between 0.5 and 2 cm for example, and after an approach stroke x which is practically zero for cam 102 and always low for the other three cams. This manipulator, which only has two rigid parts which can be adapted to the style of the board. edge, and whose installation is easy, allows, thanks to the three pockets, two of which are partially superimposed, and to the four cams, to perform other different functions, three of which, as in the previous examples, position functions of the mirror by pivots..ent in these particular directions, by a compression of the pocket 93 and the non-superimposed parts of the pockets 94 and 95, the corpression being obtained by pressing on the floating segment 97, at case level these lC0, 101 and that not shown, which are marked with the symbols
H, B and α on the top of the push-button 97. The fourth function is a particular function which, in the example of application to the pivoting control of a rear-view mirror, can be a command for rapid positioning of this rear-view mirror in a predetermined position, by compression of the portions of superimposed pockets 94a and 95a, - the compressing sound being obtained by pressing the pusher 97 at the level of the symble H. The stroke of the pusher 97 is such that, when the user presses at this area, the cams 100 and 101 of the pusher 97 are practically tangent to the pockets 94 and 95. Pressing these two pockets simultaneously has the effect of orienting the mirror along a privileged axis Y, Y ′, predetermined and shown in FIG. 10d , which is explained below, while the angular adjustment of the positioning is carried out by pressing on the zone marked in α on the pusher 97, and by compression of the pocket 93. The ratio of the volume of the portions of pockets 94a and 95a which are superimposed on the volume of each of the pockets 94 and 95 is chosen so that the rapid approach function is fulfilled. the position of the axis Y, Y 'is not exactly that which is desired by the user, the correction is ensured by compressing one of the pockets 94 and 95 separately, by pressing on one of the two zones marked H and B on pusher 97.

 In FIG. 10d, the rectanale A, A ', B, B' represents the envelope of the extreme positions of the eye of the driver of a car. However, in the majority of cases, the eye moves appreciably on a transverse axis, slightly inclined Z, Z ', privileged and linked to the position and / or To the driving position. The axis Y, Y 'is chosen perpendicular to the axis Z, Z', so that after the return of the driver's eye on this axis Y, Y ', by pressing on the activation zone quick seat x, the adjustment is completed by rotating the mirror by an angle α around this a :: e Y, Y ', by pressing on the area α of the russet 97.

 In FIG. 10e, there is shown diagrammatically at 103 a mirror housing in the black box 104 is positioned by three receivers interposed between the mirror and the housing of the housing. The receivers 105 and 106 are respectively connected to the pockets 95 and 94, and the receiver 107 to the pocket 93. Pressing the zone H or B corneal resnectiveet the increase in volume or receiver 1C6 cu 105, this does respectively pivot the mirror up or down. Pressing the α controls, by increasing the volume of the receiver 107, the pivoting of the mirror around the axis passing through the centers of the receivers 105 and 106, and pressing on the area X controls a simultaneous action on the two receivers 105 and 106, this which immediately moves the mirror so that the driver's eye is on the Y, Y 'axis.

 Such a manipulator with three pockets and four functions can be generalized to a manipulator comprising n deformable pockets and n + l, n + 2 ... n + p functions, if there are overlaps of at least two pockets among the n available in the manipulator.

 In a simpler variant, the pockets 94 and 95 have no overlap, so that there is a manipulator with three deformable pockets for controlling the positioning of the mirror by the combination of three different commands or functions.

 The manipulator 110, schematically shown in Figures ila and llb is a variant of that described below with reference to Figures 10a to 10c, and it operates according to es principles, that is to say it allows d '' ensuring three controls for positioning the rear-view mirror and a command for rapid positioning of the rear-view mirror in a predetermined position. The essential difference is that the base of this manipulator 110 has an additional imprint in the central part of its bottom, and in this imprint additional is partially housed and retained, an additional deformable pocket 112, around which a pocket 113 is distributed, in the lower position in FIG. 11a and corresponding to the pocket 93 of the previous example, and two side pockets 114 and 115, in the shape of an L which overlap partially in the upper part of the base (on ricre lla! and which correspond to the pockets 94 and 95 of the previous example. n look at the pocket ce ntrale 112, without overlap with the other pockets, the pusher 117 (see FIG. 11b) has an additional and central cam 118, in the form of a hemispherical seat, the volume of which corresponds to that of the pocket 112, ie for example 2 cm 3 corresponding to a thickness of 0.5 cm and a section of 4 cm 2. The hemispherical shape of the central cam 11S allows, when the pusher 117 is pressed by pressing on the central zone V of the pusher, at the level of the central cam 118, to simultaneously compress at least one other pocket 113, 114 or 115, by pivoting of the pusher 117 on the hemispherical cam 118. The approach stroke of the hemispherical cam 118 relative to the central pocket 112 is the shortest of the strokes approach of all the cams with respect to the corresponding pockets, and the maximum stroke of this cam 118 is such that after the cam 118 has been pressed onto its maximum stroke, the cam 122, which is presented by the pusher 117 opposite the superimposed portions ées of the pockets 114 and 115, on the side opposite to the cam 119 of compression of the pocket 113, comes flush with the two superimposed portions of the pockets 114 and 115. The least pi votes .- .. ent cu pusher 117 by rotation on the square hemispherical 118, obtained by pressing on the area x of the pusher 117 then makes it possible to compress the superimposed pockets for the rapid installation of the mirror. For the rest, this ranipulator works like that of the previous example.

The manipulator of FIGS. 11a and 11b, comprising four pockets, two of which are partially superimposed, and these cams, thus fulfills five control functions, and can be used to control accessories other than a rear view mirror.

In the case of ordering a rear view mirror, the additional function linked to the presence of the pocket 112, which is the first compressed when the push button 117 is actuated, may be a clutch or unlocking control of the rear view mirror, Corsican described below with reference to -icures 16a to lec.

 Like the previous ones, this manipulator can also be adapted to the style of the dashboard, and the relative values of the volumes of the pockets can be chosen according to the desired strokes of the controlled member.

In FIG. 12, there is schematically shown a control device comprising a single manipulator usable for selectively controlling one or the other of two controlled members, for example an exterior mirror on the right side and an exterior mirror on the left side on a motor vehicle. The position of the right-hand mirror is determined by three deformable receiving pockets for positioning 130, 131 and 132, while the position of the left-hand mirror is determined by the three deformable receiving pockets from positioning 133, 134 and 135.Each of the receiving pockets positioning 130 to 135 is in communication. by a low-volumetric inlet channel, with a deformable isolation pocket 136 to 141, of significantly smaller volume than that of the corresponding positioning pocket, and the isolation pockets 136 and 139 are connected in parallel to a sort of connection tube 142, while the isolation pockets 137 and 140 are connected in parallel to the same connection tube 143 and that the insulation pockets 138 and 141 are connected in parallel to the same connection tube 144, each of these tubes, this connection 142, 143 and 1.4 is connected to the deformable transmitting base for corresponding positioning, respectively 145, 146 and 147, these three transmitting positioning pockets being housed in the body 149, fitted by a cover 150, of the channel switching maniculator 148, this body 149 having three openings through each of which the user can exert direct support on a corresponding pocket among the three emitting positioning pockets 145 to 147, of which each is housed in a corresponding compartment of the body 149. The latter e C in handle attached by a tubular reed 151 to a substantially rectangular base 152 mounted rotated around its longitudinal axis O, O 'on a support not shown in the figure . On either side of the longitudinal axis O, O ', the base 152 has one of two oblong and symmetrical windows in each of which is housed one of two deformable pockets emitting shutters 153 and 154, which are retained on the support and each connected by one of two connecting tubes 155 and 156 to one of two deformable pockets receiving shutters 157 and 158. These pockets 157 and 158 are elongate deformable pockets maintained respectively in the right-hand mirror casing and in the left-hand mirror casing, one 157 in the pressure transmission configuration with the three deformable isolation pockets 136 to 138 upstream of the deformable receiving pockets for positioning 130 A 132 of the right mirror, and the other 158 in pressure transmission configuration with the three flexible insulation pockets 139 to 141, upstream of the deformable receptor positioning pockets 133 to 135 of the left rear-view mirror. Thus, when the user r pivots the manually actuated control member constituted by the body 149 and the base 152 to the left in FIG. 12, around the axis O, O ', the base 152 compressed the transmitter pocket of obturation 153, which transfers, via the tube 155, pressurized hydraulic fluid into the obturation receptacle pocket 157, which increases in volume and simultaneously compresses the three isolation pockets 136 to 138, reduced their flush volume, so that the three receiving pockets these for positioning 130 to 132 of the rear view mirror are isolated from the connecting tubes 142 2 144. As a result, any compression by the user of the emitting pockets for positioning 145 to 147 in the body 149 of the manipulator 148 has no consequence on the condition of the receiving pockets for positioning the rear view mirror and that only the receiving pockets for positioning 133 to 135 cu left rear view mirror can receive command orders modifying the orientation of this left rear view mirror he, by means of isolation pockets 139 to 141, not compressed, and connecting tubes 142 to 144, which pass through the tubular handle 151 to be connected to the transmitter transmitter pockets 145 to 147. Conversely, when nanipulator 143 is pivoted to the right around the axis
O, O 'from its base, the shutter-emitting pocket 154 is compressed, which inflates the shutter-receiving pocket 158 and compresses the isolation pockets 139 to 141, so that the receptor positioning pockets 133 to 135 of the left rear view mirror are isolated from the transmitting positioning pockets 145 to 147. This prohibits the change of orientation of the left rear view mirror, and only the position of the right rear view mirror can be modified by action on the transmitting positioning pockets 145 to 147, in communication through the tubes 142 to 144 and the isolation pockets 136 to 138 with the receptor positioning pockets 130 to 132.

 This manipulator 148, with switching of the control channels to the two mirrors combines the principle of the direct contact ranipulator on three deformable positioning emitter pockets, connected to three deformable pockets for positioning the controlled member, with a pivoting of of the manipulator, on one side or the other, in order to allow the transmission of the positioning control orders only to one or the other of two horned members, for example on the left to control the mirror on the left and on the right to control the orientation of the right-hand mirror. Compared to the position-receiving receptacles 130 to 132 and 133 to 135, the small isolation pockets respectively 136 to 138 and 139 to 141 fulfill the function of valves preventing the hydraulic fluid coming from the transmitting positioning pockets 145 to 147 from penetrating respectively into the receiving positioning pockets 130 to 132 and 133 to 13z, when e respectively the shutter-receiving pocket 157 or 158 is inflated by the compression respectively of the shutter-transmitting pocket 153 or 154.

In this example, the volume of the transmitter transmitting pockets 145 A 147 is twice that of the receiver positioning pockets 130 to 135, and it is obvious that each transmitter transmitting pocket 145 A 147 is connected in parallel to the two pockets position receivers which control the positioning in the same direction of the two adjustable mirrors.

 FIGS. 13 and 14 show a connector used to connect connecting tubes which, in the absence of this connector, would be too long and too difficult to install between deformable transmitting pockets and corresponding deformable receiving pockets, by example of the positioning pockets of a mirror. In addition, as already explained in the European patent application mentioned above, an advantage linked to the presence of such a connector is, in the event of damage, of a hydraulic circuit in the circuit part situated on the side of the transmitting pocket or coaches the circuit part cu side of the receiving pocket, which only the faulty part is to be replaced. Such a connector therefore makes it possible to connect and separate the two complementary parts of a hydraulic circuit without having to empty the transmitting and / or receiving pockets.

 This connector 16d comprises a body molded in one piece from a synthetic material and consisting of two flaps 161 and 162, articulated relative to each other by a flexible hinge formed by a narrow tongue 164 between two parallel lines and thinned material 165, forming the folding axes: <, X, X 'and Y, Y'. One of the flaps constitutes a base 161, the external face of which projects projecting lugs 166 for elastic snap fastening on a support 167, and the edge opposite to the flexible hinge 163 carries two elastically deformable hooks 168 to allow the removable closure of the body by folding the flap 162, forming a cover, against the base 161 and elastic snap-fastening of the hooks 168 over the edge of the cover 162 on the side opposite the hinge 163, as shown in cross section on the figure 13.

Each of the two flaps 161 and 162 has, in its internal face, three recesses or imprints of rectangular shape, and each of the three recesses of one of the green flaps opposite a recess corresponding to this other flap, when these two flaps are folded and fixed against each other. In each of the recesses of the flap 161 is housed a deformable pocket 169, of corresponding shape, the connecting tube 169a of which passes through one of the notches provided for this purpose in the edge of the flap 161. Similarly, deformable pockets 170 are housed in the three recesses of the shutter 162, and their connecting tube 170A also passes in notches formed in the edge of this shutter 162, on the side opposite to that by which the tubes 169a come out of the connector. When the two flaps 161 and 162 are fixed against each other, this means that the convector is closed, the pockets 170 are each compressed against one of the pockets 169, so that this volume increases by one leads to a decrease in the other of the volume being, the pockets being two to two e configuration of transmission of this pressure. The three tubes this link 169a are connected to the three deformable pockets emitting this positioning of a manipulator for controlling the positicn nerent of a rear-view mirror, then the pockets 169 constitute connection receiving pockets, the increases in volume of which cause decreases in the volumes of the pockets 170, constituting connection transmission pockets, the connecting tubes 170a of which are connected to the three receiving pockets of positioning of this mirror, to which the volumes of hydraulic fluid flushes from the pockets 170 of the connector are transmitted to ensure this positioning.

 Such a connector can be interposed between a manipulator according to the examples described with reference to Figures la to 6b and 8a to 10c, and corresponding positioning receivers. but it may, in variants, include more than three transmitter and receiver connection pockets, to also relay clutch or release orders, in combination with manipulators according to FIGS. 7a, 7b and 11a, 11b, Finally, it can be mounted between the insulation pockets 136 to 138 and 139 to 141 on the one hand, and, on the other hand the bifurcation points of the tubes 142 to 144, in a control device according to FIG. 12.

 However, to suit a device fitted with a channel-switching manipulator, an adapted variant of connectors is proposed, which is shown diagrammatically in FIG. 15.

 This track-switching connector 171 comprises, like that of the previous example, a single connector body, molded in one piece from a material, and comprising two flaps 172 and 173, substantially rectangular, seen in plan, articulated relative to each other approximately around an axis O, O 'by a flexible hinge 174, one of these flaps constituting a base 172 for fixing or connector by any suitable means, for example by elastic snap-fastening on a support (not shown), while the other flap forms a cover 173 carrying removable fastening means, also of any known suitable type, such as hooks 175 for elastic snap-fastening, Oven fix the cover 173 against the base 172, by snapping these hooks 175 above the edge of the base 172, on the side opposite the hinge 174. Similarly, as in the previous example, each of the flaps 172 and 173 has, in its internal face, recesses or imprinted es in which are housed deformable pockets of corresponding shape, selectively bearing against one another, in pressure transmission configuration, when the connector 171 is closed by fixing the cover 173 against the base 172.

More specifically, as this connector 171 is intended to be mounted between, on the one hand, a channel switching manipulator, such as that of FIG. 12, comprising three deformable emitting positioning pockets 145 to 147 and two deformable emitting pockets of shutter 153 and 15, and, on the other hand, two controlled members, such as the left and right exterior mirrors of a motor vehicle, and each of which is positioned by the action of three deformable positioning receptive pockets, such as the pockets 130 A 132 and 133 to 135 respectively in FIG. 12, the flaps 172 and 173 house the following deformable pockets
the base 172 receives, on the side of its edge opposite the flexible hinge 174, six deformable pockets receiving receptacles 176 to 181, each of which is in communication by a small volute channel with a small deformable pocket c ' isolation respectively 182 to 187, these pockets.

being arranged symmetrically in groups of three on either side of the transverse median axis, perpendicular to the axis of articulation o, O ', and, te pus, these pockets are connected in three pairs of symmetrical pockets apartte- for the two groups, the isolation pocket 182 being connected to the isolation pocket 187 by a channel 188 at the midpoint of which opens the downstream end of a tube 189 for connection to one of the emitting positioning pockets , as cue the pocket 145 in Figure 12; similarly, the isolation pockets 183 and 186 are in communication with each other by a channel 190 into which the downstream end of a tbe 191 for connection to another emitting positioning pocket, such as the pocket 146 of the manipulator of FIG. 12, and the isolation pockets 184 and 185 are in communication with each other by a channel 192 into which opens the downstream end of a tube 193 for connection to the third transmitter positioning pocket 147 of the manipulator of Figure 12; the connection receiving pockets 176 to 181 thus being connected in pairs to one respectively of the three transmitting positioning pockets 145 A 147 of the control manipulator by means of their isolation pocket respectively 182 to 187, of their channel connection 188, 190 or 12, and their connection te 189, 191 or 193, which all three extend perpendicular to the plane of the pockets and flaps of the connector.

 the cover 173 receives, on the side of its edge opposite the hinge 174, six transmitting connection pockets 194 to 199, each of which is in communication by a connecting tube respectively 194a to 199a, with a receiving pocket for corresponding positioning of the two mirrors ; more precisely, the emitting connection pockets 194 and 199, which are in the configuration for transmitting this pressure, when the connector is closed, with the connection receiving pockets 176 and respectively.

181 hooked up to the erector positioning pocket 145 of the menipulator of FIG. 12, are respectively connected by their tube, this connection l-.a and 199a to the receiving receptacles 130 and 133 respectively controlling in the same direction the positioning of the right rear view mirrors and left; in a similar manner, the connection transmitter pockets 195 and 198, in the pressure transmission configuration when the connector 171 is closed, with the connection reception pockets 177 and 18C respectively connected to the same positioning transmitter pocket 146 of the manipulator of FIG. 12, are respectively connected by their connection tube 195a and 198a to the receptor positioning pockets 131 and 134 controlling the positioning in a second direction of the right and left mirrors respectively, and finally the transmitter transmitter pockets 196 and 197, in pressure transmission configuration with respectively the receiving receptacles for connection 178 and 179 both connected to the same emitting positioning pockets 147 of the manipulator, are respectively connected by their connecting tube 196a and 197a to the receiving receptacle for positioning 132 and 135 controlling in a third direction the positioning respectively of the ret Right and left rear view mirrors. On the side of the hinge 174, the cover 173 also accommodates two in the form of three shutter receiving pockets in series, the first set comprising the shutter receiving pockets 200, 201 and 202, connected in series by small channels, and each at one of the three respectively transmitting connection pockets 194 to 196 which are on the same side of the transverse median axis of the connector, perpendicular to the axis O, O ', and symmetrically, the second set includes the closing receptacle pockets 203, 204 and 205 connected in series by small channels and each at one of the three transmitting connection pockets respectively 197 Ai 199, which are on the corresponding side of this transverse median axis of the connector 171. In addition, the central closure receiving pocket 201 of the first assembly is in communication by the connecting tube 206 with one of the two emitting rocks closing the manipulator. geese, for example with the pocket 153 of the manipulator of FIG. 12, while the central shutter-receiving pocket 204 of the second set is in communication by the connecting tube 207 with the other shutter-emitting pocket 154 of the same manipulator Finally, when the connector 171 is closed, the shutter receptacle pockets 200 to 205 are in the pressure transfer configuration with the isolation pockets 182 A 187 respectively.

 In this way, the connector 171 being closed, if the user rocks the manipulator 148 of FIG. 12 to the left in this figure, he compresses the sealing shutter pocket 153, which expels hydraulic fluid under pressure by the tube 206 towards the receiving receptacles for closure 200 to 202, which inflate and compress respectively the isolation pockets 182 to 184. As a result, the connection receiving pockets 176 to 178 are isolated from tubes 189, 191 and 193, and therefore the transmitting positioning pockets 145 Fi 147 of the manipulator. In sequence, any compression of one of the transmitting positioning pockets 145 to 147 of the manipulator causes a corresponding swelling of the corresponding connection receiving pocket 179 to 181. This increase in volume, from one of the pockets 179 to 181 causes a reduction in the volume of the corresponding connection transmitting pocket 197 to 199, and therefore the transmission of hydraulic fluid under pressure to the corresponding positioning receptor pocket 133 to 135 of the left mirror in FIG. 12, and the transmission of any positioning command command to the mirror believes is impossible. Conversely, if the user moves the manipulator 148 of FIG. 12 on the right, he compresses the shutter-emitting pocket 154, which inflates the shutter-receiving pockets 203 to 205, by transfer of hydraulic fluid under pressure by the tube 207. The swelling of the pockets 203 to 205 causes the compression of the isolation pockets 135 to 187, and the reduction in their volume has a minimum value preventing any communication between the connection receiving pockets 179 to 181 and the tubes 189, 191 and 193 for connection to the three transmitting pockets for positioning 145 to 147 of the manipulator. As a result, the connection receiving pockets 179 to 131 are isolated and cannot change in volume, as well, consequently, as the pockets connection 197 to 199, so that no order command for positioning the right mirror can be transmitted to it. On the other hand, any compression of the transmitting positioning pockets 145 to 147 cu manipulator causes swelling of the corresponding connection receiving pockets 176 to 178, and therefore a corresponding reduction in volume of the corresponding connection transmitting pockets 194 to 196, which transmits fluid under pressure to the corresponding positioning receptive pockets 130 to 133, to control the orientation of the rear view mirror.

 In order to allow access to the different pockets of the connector which correspond to one of the two mirrors, while retaining the protection provided by the body of the connector 171 to the pockets corresponding to the other mirror, the cover 173 of the connector is subdivided into two halves 173a and 173b, adjacent along the transverse median axis of the connector 171, which is represented by dotted lines on the cover 173, each half of the latter carrying one of the two elastic latching pins 175 on the base 172.

 Comparison of the connector of FIG. 15 with that of FIGS. 13 and 14 as well as with the control device of FIG. 12 makes it possible to note that the isolation pockets 136 to 141 and the receptacle closure pockets 157 and 158 of the control device of FIG. 12, which are installed just upstream of the corresponding positioning receptive pockets 130 A 132 and 133 to 135 of the two mirrors and in the housings or protective boxes of the latter, have been replaced by pockets respectively 'isolation 182 A 187 and receptor closure pockets 200 A 205 disposed in the connector, respectively just in which receptor cor.nexion receptacles 176 to 181, which correspond to the pockets 169 of the connector of Figure 14, and for the receptor closure pockets 200 to 205, just near the transmitter pockets of, connection 194 to l99, which correspond to the pockets 170 of the connector of FIG. 14.

 Consequently, the channel-switching connector of FIG. 15 has two advantages: it makes it possible first of all to reduce the length of the tubes connecting the emitting shutter pockets to the receiving shutter pockets, and above all it makes it possible to reduce the '' overall dimensions of the pockets directly necessary in the housing or mirror housing, these pockets being limited to the receptor pockets for positioning as well as possibly one or more clutch or release pockets, as described below below with reference to the figures there 18c.

 In FIG. 16a, there is shown schematically and partially a vehicle exterior mirror whose positioning is controlled by a hydraulic remote control device according to the invention, this mirror being of the type shown in FIG. 4 of the request for European patent NO 0152219, with which it has many common characteristics, this structure, and advantageously refer to the description.

of this European patent application for more detail on the operating mode, which is almost identical to that of the rear view mirror of FIG. 16a. This dexnier comprises a casing 210, curved to offer less aerodynamic drag and to delimit, on the side of its concavity, a housing in which a mirror 211 is fixed by its rear face on a plate 212 which is on the one hand retained by articulation members on a support 213 fixed inside the casing or housing 210, and on the other hand moved relative to this support 213 by three positioning receivers such as that identified as a whole at 214.

This receiver essentially comprises a deformable position-receiving pocket 215, connected by the connecting tube 216 directly or indirectly (via a connector as described above) to an emitting pocket for positioning a manipulator. also as described above. The positioning receiving pocket 215 is disposed in a cylinder 217 fixed on the support 213 and having, on the side of the mirror 211, an axial guide bore of the part of smaller diameter of a stepped piston 218, the part of which more large diameter is received in the cylinder 217 and pressing on the pocket 215 which itself bears against the support 213, so that if the volume of the pocket 215 increases, due to a compression of the transmitting pocket of corresponding positioning, the piston 218 is pushed back towards the mirror 211 and the plate 212, and it pushes back itself these two elements towards the outside, which modifies in a corresponding way the orientation of the mirror 211 compared to the support 213 by the effect of the articulation means these comprise on the one hand a semi-ball joint 219, housed in a central and hemispherical cup 220 of the plate 212, and mounted around a tioe 221 which passes through an orifice at the bottom of the bowl 220 and in an orifice of the support 213, and whose end closest to the casing 210 is integral with a radial cup 222.A helical compression spring 223 surrounds the portion of rod 221 extending and the support 213 and the casing 210, and this spring 223 bears on one side against the support 213 and on the other against the cup 222, so as to bias the rod 221 axially towards the casing 210, and therefore the half-ball joint 219 against the cup 220 of the plate 212, which keeps the latter in abutment against the piston 218 and pushes the latter against the pocket 215. On the other hand, the articulation means comprise two friction surfaces in contact with one another to hold the mirror 211 in the occupied position after movement by the fact these receiving pockets such as 215, one of these two friction surfaces being a surface in the form of a convex spherical cap 224 presented by the plate 212 in protrusion towards the housing 210 and concentric Half-rotu 219, while the other friction surface is a surface in the shape of a concave spherical cap 225, presented by the support 213 projecting towards the mirror 211 and also concentric with the semi-ball joint 219. In such an assembly, it is clear that the spring 223 has the effect of keeping the bearing surfaces, of friction 224 and 225 in contact with one another, which offers significant resistance to the efforts to control the pivoting of the plate 212 by the cup 220 around the semi-ball joint 219. In order to eliminate or, at least, to reduce to a significant extent this resistance to pivoting of the mirror 211 and of its plate 212 with respect to the support 213, the casing 210 has, opposite this cup 222 and from the end of the rod 221, a circular recess 226 (see FIG. 16b) formed in a bulge 227 of the casing 210, and a deformable unlocking receiving pocket 228, with flexible wall, is housed in the recess 226 and connected by a connecting tube 228a
a deformable check emitting release, such as, for example: r.? le, the pocket 112 of the manipulator of Figure-lla.

In this way, a compression on this unlocking emitting pocket causes a decrease in its volume, which directly causes one indirectly (via a connector if necessary) an increase in volume that the unlocking receiving pocket 228, which has the effect of exerting on the cup 222 and the rod 221 a force antagonistic to that of the spring 223, this tending to loosen any contact between, on the one hand, the half-ball joint 219 and the cup 220, and, on the other hand, between the two friction surfaces 224 and 225.

 I1 follows that the pivoting of the bowl 220 of the plate 212 around the half-ball joint 219 and under the effect of increases in volume of the receptor positioning pockets 215 are facilitated. This device therefore has a very high sensitivity to control orders.

After releasing the emitting unlocking pocket, the spring 223 compresses the unlocking receiving pocket 228 and again ensures the friction contact between the surfaces 224 and 225, and of the semi-ball joint 219 against the bowl 220, which mobilizes the mirror and its plate in the position they occupied at that moment. In this device, the setting of the spring 223 makes it possible to obtain a greater or lesser friction between the surfaces 224 and 225, and also to eliminate any risk of vibration of the mirror 211 and of its plate 212, while retaining the possibility of adjustment. very flexible, with little effort on the positioning pockets such as 215, when the device is disengaged by swelling of the release pocket 228.

 FIGS. 17a and 17b schematically and partially represent a variant of the rear-view mirror of FIG. 7a which is essentially distinguished therefrom by the embodiment of the members of the unlocking mechanism or of this clutch clutch. We find in this variant a 23G mirror housing, in which the mirror 231 is fi> :: é on a plate 232 retained on a support 233 internal to the housing 230 by means of articulation With ball joint, as well as a range of convex friction 234 in the form of a spherical cap projecting from the plate 232 on the side of the casing 230, and cooperating with a concave friction surface 235, also in the form of a spherical cap, which surrounds the surface 234 and is supported by the support 233 and projecting towards the plate 232. The particular characteristics of this variant are that the concave surface 235 is formed on the axially external part of the radially internal face of a skirt 236 which is, on the one hand, peripheral to the support 233 in the form of base arranged in circular disc, and on the other hand subdivided in curved and contiguous flaps and segments separated from each other by radial slots 237 formed in the skirt and regularly distributed around a groove annular formed in the periphery of the circular base 233. In this groove is arranged the unlocking receiving pocket 238, which is a deformable pocket with variable volume and flexible wall, in the form of an elongated rod and bent in the groove so forming an O-ring pocket in an almost complete loop, connected to the deformable pocket emitting or unlocking control by the connecting tube 238a at one end of the tube (see Figure 17b). When the unlocking emitting pocket is compressed, the unlocking receiving pocket 538 is inflated, which causes the radial separation of the flaps of the skirt 236 and of the concave segments 235 relative to the convex bearing surface 234, and against the elastic return of these flaps and skirt segments to the initial position, due to the realization of the skirt in an appropriate synthetic material.

Thus, the convex surface 234 is released from its pressure contact against the concave segments 235, which allows its relative displacement with the plate 232 and the mirror 231 by the action of the positioning receivers, not shown, but also mounted in this rear view mirror between the base 233 and the plate 232. This variant has the advantage that it does not include the tice 221, the cup 222 and the spring 223 which are necessary for the preceding example.

 FIGS. 18a to 18c show another variant of a mirror with an unlocking or clutch-declutching mechanism facilitating the action of the positioning receivers and comprising only two relatively rigid parts in addition to the unlocking receiver. In this variant, there is a casing 240 in which the mirror 241 is fixed to a plate 242 with an over-thickened central part and this revolution 243, the base 241 of which is ternurned towards the casing 240 has a central and hemispherical boss 245, projecting towards the casing 240, and engaged in a ball joint in a recess in the form of a spherical cap formed in a boss or bulge 245 presented projecting on the bottom of the casing 240. The lateral surface of the central part 243 of the plate 242 forms a bearing surface in a convex spherical cap 247 with the same center as the hemispherical boss 245, and yes cooperates with a concave bearing surface, discontinuously surrounding the convex bearing surface 247, and delimited on the internal and concave faces, in portions of spherical cap of fingers 248 regularly distributed around the bearing 247 and each integral cu car ter 240 by its thinned foot 249 which delimits, on the side facing the convex bearing 247, a recess t in an arc in the circumferential direction around the central part 243 of the plate 242. In each of these recesses is housed one of the cylindrical and inflatable tubes 250. of a string of tubes connected in series by small channels 251 of low internal volume, as shown in FIG. 18c, and which form the deformable pocket receiving the unlocking of this device. The swelling of these tubes 250 by the compression of a transmitter pocket or corresponding unlocking control causes a radial spacing of the fingers 248 Against their elastic return, which ensures cooperation with the convex surface 247 and maintains the half-ball 245 against the bottom of the recess of the bulge 246. The radial spacing of the fingers 248 releases the convex bearing surface 247 from its support against the concave bearing portions inside the fingers 248, which facilitates pivoting of the mirror 241 and of its plate 242 relative to the casing 240, by the action of the positioning receivers housed for example against the fingers 248 and the periphery of the casing 240.

 In this example, the center O of the hemispherical boss 245 of small radius is the center of rotation of the mirror 241 and of its plate 242, as well as the center of the convex surface 247 of large radius and of the envelope of the portions of concave surface on the internal faces * of the four or six fingers 248, the radial stroke of which, although small when the bags 250 are inflated, is sufficient to make the central part 243 mobile by pivoting between the fingers 248.

Of course, alternative embodiments are possible. One of the two flaps 161, 162 could tOF2eeh three recesses intended each to receive a connection transmitting pocket 170. and a connection receiving pocket 169 while the other flap would have the shape of a
flat cover or one of the two flaps 161, 162 could comprise a recess intended to receive a connection transmitter pocket 170 and a receiver pocket for
connection 169 while the other flap would include two recesses each intended to receive a pocket for transmitting
