Description
L'invention concerne une pince de démontage d'une gaine de réception en coulissement d'une tige de montage d'appui-tête de siège de véhicule automobile.The invention relates to a dismounting clamp for a sliding receiving sheath of a motor vehicle seat headrest mounting rod.
Il est connu de réaliser une gaine - notamment en matériau plastique moulé - de réception en coulissement d'une tige de montage d'un appui-tête de véhicule automobile, ladite gaine comprenant un corps tubulaire de réception de ladite tige, ledit corps comprenant deux languettes inférieures rétractables élastiquement vers l'intérieur dont l'extrémité libre est destinée à s'ancrer sur une structure - notamment sous forme de douille métallique solidaire du dossier dudit siège - de réception de ladite gaine, lesdites languettes étant diamétralement opposées l'une à l'autre, ceci par rapport à l'axe de révolution selon lequel s'étend généralement ledit corps tubulaire.It is known to produce a sheath - in particular of molded plastic material - for sliding reception of a mounting rod of a motor vehicle headrest, said sheath comprising a tubular body for receiving said rod, said body comprising two lower tongues retractable elastically inward, the free end of which is intended to be anchored to a structure - in particular in the form of a metal sleeve integral with the backrest of said seat - for receiving said sheath, said tabs being diametrically opposed to each other; the other, this with respect to the axis of revolution according to which generally extends said tubular body.
Avec un tel agencement, on peut aisément démonter la gaine de sa structure de réception, ceci par pincement des languettes l'une vers l'autre, permettant de dégager les extrémités libres de ladite structure, opération qui peut être notamment requise lors d'une réparation du siège.With such an arrangement, the sheath of its receiving structure can be easily dismounted by pinching the tongues towards one another, making it possible to disengage the free ends of said structure, an operation which may be required in particular during a repair of the seat.
Il est également connu de réaliser une gaine dont les languettes sont décalées l'une de l'autre d'un angle de sensiblement 90°, ceci par rapport à l'axe de révolution sus évoqué. Dans ce cas, le démontage de la gaine de son support est complexe puisqu'on ne peut plus se contenter d'un pincement des languettes l'une vers l'autre. L'invention a pour but de proposer un outil permettant de mener à bien un tel démontage.It is also known to make a sheath whose tabs are offset from one another by an angle of substantially 90 °, this with respect to the axis of revolution mentioned above. In this case, the disassembly of the sheath of its support is complex since we can no longer be satisfied with a pinching of the tongues towards one another. The invention aims to provide a tool for carrying out such disassembly.
A cet effet, l'invention propose une pince de démontage d'une gaine de réception en coulissement d'une tige de montage d'appui-tête de siège de véhicule automobile, ladite gaine comprenant un corps tubulaire de réception de ladite tige, ledit corps comprenant deux languettes inférieures rétractables élastiquement vers l'intérieur dont l'extrémité libre est destinée à s'ancrer sur une structure de réception de ladite gaine, lesdites languettes étant décalées l'une de l'autre d'un angle de sensiblement 90°, ladite pince comprenant : - une branche fixe dont une extrémité est pourvue d'un plateau, - deux paires de mâchoires montées en rotation sur ledit plateau de manière à pouvoir débattre entre une configuration desserrée et une configuration resserrée, lesdites mâchoires saillant vers le haut dudit plateau et étant positionnées les unes par rapport aux autres selon une symétrie d'ordre quatre par rapport à un axe sensiblement vertical, - une branche mobile montée en rotation par rapport audit plateau selon ledit axe, de manière à être actionnable entre une position écartée et une position rapprochée de ladite branche fixe, - quatre éléments de came solidaires de ladite branche mobile, lesdits éléments coopérant avec quatre éléments réciproques prévus sur lesdites mâchoires de manière à faire passer lesdites paires de mâchoires de leur configuration desserrée vers leur configuration resserrée lorsque ladite branche mobile est actionnée depuis sa position écartée vers sa position rapprochée.For this purpose, the invention proposes a dismounting clip for a sliding receiving sheath of a motor vehicle seat headrest mounting rod, said sheath comprising a tubular body for receiving said rod, said body comprising two lower tabs retractable elastically inward, the free end is intended to be anchored to a receiving structure of said sheath, said tabs being offset from each other by an angle of substantially 90 ° said gripper comprising: - a fixed branch whose one end is provided with a plate, - two pairs of jaws rotatably mounted on said plate so as to be able to debate between a loosened configuration and a constricted configuration, said jaws projecting upwards of said plate and being positioned relative to each other in a symmetry of order four with respect to a substantially vertical axis, - a movable limb the rotation in rotation relative to said plate along said axis, so as to be operable between a spaced position and a position close to said fixed branch, - four cam members secured to said movable branch, said elements cooperating with four reciprocal elements provided on said said jaws so as to move said pairs of jaws from their loosened configuration to their constricted configuration when said movable branch is actuated from its spaced apart position to its close position.
Dans cette description, les termes de positionnement dans l'espace (haut, inférieur, vertical,...) sont pris en référence à la pince en cours d'utilisation sur un siège en configuration d'utilisation, son dossier étant sensiblement vertical. Lorsqu'il est dit que les languettes sont décalées de sensiblement 90°, ceci s'entend par rapport à l'axe de révolution selon lequel s'étend généralement le corps tubulaire de la gaine. Avec l'agencement proposé, la pince est en premier lieu disposée de sorte que, alors que l'on est en configuration desserrée, les mâchoires entourent les languettes. On procède alors à la mise en configuration resserrée, ceci par actionnement de la branche mobile vers sa position rapprochée. 2995 546 3 Ceci a pour effet d'exercer une rétraction des languettes vers l'intérieur, avec pour effet de dégager les extrémités libres des languettes de la structure de réception de la gaine et de permettre le démontage de ladite gaine. 5 On notera que le positionnement angulaire de la pince par rapport aux languettes et sans importance, la compression des languettes se faisant dans tous les positionnements angulaires, soit par une seule mâchoire par languette, si les mâchoires sont alignées avec les languettes, soit par deux mâchoires 10 contigües par languette, si ces dernières sont « à cheval » sur deux mâchoires. D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes, dans lesquelles : - les figures 1 sont une vue générale d'un ensemble pince/gaine, les 15 mâchoires de la pince étant en configuration desserrée (1a), la branche mobile étant en position écartée, et en configuration resserrée (1 b), la branche mobile étant en position rapprochée, - les figures 2a et 2b sont des vues de détail respectives partielles des figures 1 a et 1 b, 20 - les figures 3a et 3b sont des vues respectives en coupe verticale partielle des figures la et lb. En référence aux figures, on décrit une pince 1 de démontage d'une gaine 2 notamment en matériau plastique moulé - de réception en coulissement d'une 25 tige de montage d'appui-tête de siège de véhicule automobile, ladite gaine comprenant un corps 21 tubulaire de réception de ladite tige, ledit corps comprenant deux languettes 22 inférieures rétractables élastiquement vers l'intérieur dont l'extrémité libre 23 est destinée à s'ancrer sur une structure de réception - non représentée et notamment sous forme de douille métallique 30 solidaire d'un dossier dudit siège - de ladite gaine, lesdites languettes étant décalées l'une de l'autre d'un angle de sensiblement 90°, ladite pince comprenant : - une branche fixe 3 dont une extrémité est pourvue d'un plateau 4, - deux paires de mâchoires 5 montées en rotation sur ledit plateau de manière à pouvoir débattre entre une configuration desserrée et une configuration resserrée, lesdites mâchoires saillant vers le haut dudit plateau et étant positionnées les unes par rapport aux autres selon une symétrie d'ordre quatre par rapport à un axe 6 sensiblement vertical, - une branche mobile 7 montée en rotation par rapport audit plateau selon ledit axe, de manière à être actionnable entre une position écartée et une position rapprochée de ladite branche fixe, - quatre éléments de came 8 solidaires de ladite branche mobile, lesdits éléments coopérant avec quatre éléments réciproques 9 prévus sur lesdites mâchoires de manière à faire passer lesdites paires de mâchoires de leur configuration desserrée vers leur configuration resserrée lorsque ladite branche mobile est actionnée depuis sa position écartée vers sa position rapprochée.In this description, the terms of positioning in space (top, bottom, vertical, ...) are taken with reference to the clamp in use on a seat in use configuration, its backrest being substantially vertical. When it is said that the tongues are shifted by substantially 90 °, this refers to the axis of revolution in which generally extends the tubular body of the sheath. With the proposed arrangement, the clamp is first arranged so that, while in the loosened configuration, the jaws surround the tabs. The tightened configuration is then carried out by actuating the movable arm towards its close position. 2995 546 3 This has the effect of exerting a retraction of the tongues inwardly, with the effect of disengaging the free ends of the tongues of the receiving structure of the sheath and allowing disassembly of said sheath. Note that the angular positioning of the clamp relative to the tabs and unimportant, the compression of the tabs being done in all the angular positions, either by a single jaw tab, if the jaws are aligned with the tabs, or by two jaws 10 contiguous by tongue, if the latter are "on horseback" on two jaws. Other features and advantages of the invention will become apparent from the description which follows, made with reference to the appended figures, in which: FIGS. 1 are a general view of a clamp / sheath assembly, the jaws of the clamp being in the loosened configuration (1a), the movable branch being in the spaced apart position, and in the constricted configuration (1b), the movable branch being in a close position, - Figures 2a and 2b are partial partial views of FIGS. 1b, 20 - Figures 3a and 3b are respective views in partial vertical section of Figures 1a and 1b. Referring to the figures, there is disclosed a clip 1 for disassembling a sheath 2, in particular of molded plastic material - slidably receiving a mounting rod of a motor vehicle seat headrest, said sheath comprising a body Tubular receiving said rod, said body comprising two lower tongues 22 retractable elastically inward, the free end 23 is intended to anchor on a receiving structure - not shown and in particular in the form of metal sleeve 30 secured a backrest of said seat - said sheath, said tabs being offset from each other by an angle of substantially 90 °, said clamp comprising: - a fixed branch 3, one end of which is provided with a plate 4 two pairs of jaws 5 rotatably mounted on said plate so as to be able to debate between a loosened configuration and a constricted configuration, said jaws protruding from s the top of said plate and being positioned relative to each other in a symmetry of order four with respect to a substantially vertical axis 6, - a movable branch 7 rotatably mounted relative to said plate along said axis, so as to be operable between a position spaced apart and a position close to said fixed branch, - four cam members 8 secured to said movable branch, said elements cooperating with four reciprocating elements 9 provided on said jaws so as to pass said pairs of jaws of their configuration loosened to their constricted configuration when said movable arm is actuated from its remote position to its close position.
La pince 1 représentée comprend en outre un premier ressort 10 de rappel de la branche mobile 7 vers sa position écartée, afin que l'utilisateur n'ait simplement qu'à la rapprocher de la branche fixe 3 pour démonter la gaine 2.The clamp 1 shown further comprises a first spring 10 for returning the movable branch 7 to its spaced position, so that the user simply has to bring it closer to the fixed branch 3 to disassemble the sheath 2.
Par ailleurs, la pince 1 représentée comprend en outre au moins un deuxième ressort 11 de rappel - ici en forme de spirale - tendant à ramener les paires de mâchoires 5 en configuration desserrée, ceci afin que ladite pince puisse directement être disposée sur la gaine 2 pour permettre son démontage.Furthermore, the clamp 1 shown further comprises at least one second spring 11 - here spiral - tending to bring the pairs of jaws 5 loose configuration, so that said clamp can be directly disposed on the sheath 2 to allow disassembly.
Selon la réalisation représentée, les éléments de came 8 sont sous forme de surfaces de came disposées sur une rondelle 12 solidaire d'une extrémité de la branche mobile 7. Les mâchoires 5 sont ici associées au plateau 4 par l'intermédiaire de saillies 13 vers le haut jouxtant la paroi interne 14 de la rondelle 12. On décrit à présent l'utilisation d'une pince 1 pour démonter une gaine 2 de sa structure de réception.According to the embodiment shown, the cam members 8 are in the form of cam surfaces disposed on a washer 12 secured to one end of the movable arm 7. The jaws 5 are here associated with the plate 4 by means of projections 13 to the top adjoining the inner wall 14 of the washer 12. It is now described the use of a clamp 1 to disassemble a sheath 2 of its receiving structure.
Avec l'agencement proposé, la pince 1 est en premier lieu disposée de sorte que, alors que l'on est en configuration desserrée, les mâchoires 5 entourent les languettes 22.With the proposed arrangement, the clamp 1 is first arranged so that, while in the loosened configuration, the jaws 5 surround the tabs 22.
On procède alors à la mise en configuration resserrée, ceci par actionnement de la branche mobile 7 vers sa position rapprochée. Ceci a pour effet d'exercer une rétraction des languettes 22 vers l'intérieur, avec pour effet de dégager les extrémités libres 23 de la structure de réception de la gaine 2 et de permettre le démontage de ladite gaine.The tightened configuration is then carried out by actuating the movable branch 7 towards its close position. This has the effect of exerting a retraction of the tongues 22 inwardly, with the effect of disengaging the free ends 23 of the receiving structure of the sheath 2 and allowing disassembly of said sheath.
