Description

La présente invention concerne un luminaire, destiné à être encastré et maintenu par pression au-travers d'une paroi d'habillage comme un faux-plafond.The present invention relates to a luminaire, intended to be recessed and maintained by pressure through a wall cladding such as a false ceiling.

Traditionnellement, les luminaires 100 encastrés, comme celui illustré à la figure 1, comprennent un corps 102 principal, généralement bordé par une paroi d'appui (non visible) destinée à venir en appui contre un côté d'une paroi 104 d'habillage, comme un faux-plafond. Ils comprennent également des moyens de rappel, comme un ressort 106 en forme de tige, agencés pour venir en appui contre l'autre côté de la paroi d'habillage, de sorte que celle-ci est prise en sandwich entre les moyens de rappel, appuyant contre un côté de cette paroi, et la surface d'appui, plaquée contre l'autre paroi. La pression exercée par les moyens de rappel permet ainsi de maintenir le luminaire en place.Traditionally, 100 recessed luminaires, such as the one illustrated in figure 1 , comprise a main body 102, generally bordered by a bearing wall (not visible) intended to abut against a side of a wall 104 of dressing, such as a false ceiling. They also comprise return means, such as a spring 106 in the form of a rod, arranged to abut against the other side of the cladding wall, so that the latter is sandwiched between the return means, pressing against one side of this wall, and the bearing surface, pressed against the other wall. The pressure exerted by the biasing means thus keeps the luminaire in place.

La mise en place des luminaires encastrés s'effectue traditionnellement en les insérant dans un trou à leur dimension ménagé dans la paroi de faux-plafond. Au cours de cette insertion, l'installateur doit maintenir avec ses doigts les moyens de rappel dans une position dans laquelle ces moyens de rappel permettent l'insertion du luminaire dans le trou de la paroi d'habillage. Lorsque les moyes de rappel sont passés de l'autre côté de la paroi d'habillage, l'installateur relâche les moyens de rappel qui viennent se plaquer violemment contre le côté non visible de la paroi d'habillage, afin de maintenir le luminaire en place.The installation of recessed luminaires is traditionally done by inserting them in a hole in their dimension formed in the wall of false ceiling. During this insertion, the installer must hold with his fingers the return means in a position in which these return means allow the insertion of the luminaire in the hole of the cladding wall. When the return means are passed to the other side of the cladding wall, the installer releases the return means which are pressed violently against the non-visible side of the cladding wall, in order to maintain the luminaire in square.

Cependant, le retour violent des moyens de rappel contre la paroi d'habillage peut avoir un effet délétère d'endommagement de cette paroi d'habillage. Cet endommagement peut survenir soit au moment de l'impact, soit au cours du temps, du fait de la pression constante exercée par ces moyens de rappel. En effet, le ressort peut pénétrer doucement dans la paroi d'habillage du fait de cette pression constante. Les dégâts provoqués peuvent être apparents depuis l'intérieur de la pièce dans laquelle est située la paroi d'habillage, si bien qu'il est alors nécessaire de la remplacer. Evidemment, si le problème se répète souvent, cela peut occasionner des frais non négligeables.However, the violent return of the return means against the cladding wall may have a deleterious effect of damage to the cladding wall. This damage can occur either at the time of impact or over time, due to the constant pressure exerted by these return means. Indeed, the spring can penetrate gently into the cladding wall due to this constant pressure. The damage caused can be apparent from the inside of the room in which the cladding wall is located, so that it is then necessary to replace it. Obviously, if the problem is repeated often, it can cause significant costs.

On notera qu'il existe des luminaires encastrés dont la tige de ressort est recouverte au moins partiellement par une gaine surmoulée. Cette gaine surmoulée vise à empêcher que la tige du ressort abîme le corps principal ou la paroi d'appui du luminaire au cas où le ressort serait par inadvertance violemment rabattu contre ce corps principal ou cette paroi d'appui, cela évite notamment d'en écailler la peinture et d'exposer conséquemment la lumière à un risque de rouille. De ce fait, c'est la gaine surmoulée, d'un matériau plus tendre que celui du corps principal ou de la paroi d'appui, qui est destinée à subir des dommages en cas d'impact. Ainsi, cette gaine surmoulée a une fonction de protection du luminaire, mais ne permet pas d'absorber l'énergie cinétique résultant du déplacement du ressort. En particulier, en cas d'impact dans le matériau fragile de la paroi d'habillage, la gaine surmoulée peut pénétrer dans cette paroi d'habillage et l'endommager.It will be noted that there are recessed luminaires whose spring rod is at least partially covered by an overmoulded sheath. This overmoulded sheath is intended to prevent the spring rod from damaging the main body or the support wall of the luminaire in the event that the spring is inadvertently violently folded against this main body or this wall. of support, this avoids in particular flaking the paint and exposing the light consequently to a risk of rust. As a result, it is the overmolded sheath, of a softer material than that of the main body or the support wall, which is intended to suffer damage in case of impact. Thus, this overmolded sheath has a protective function of the luminaire, but does not absorb the kinetic energy resulting from the displacement of the spring. In particular, in case of impact in the fragile material of the cladding wall, the overmolded sheath can penetrate into this cladding wall and damage it.

Aussi, la présente invention vise à pallier tout ou partie de ces inconvénients en proposant un luminaire, destiné à être encastré et maintenu par pression au-travers d'une paroi d'habillage, comme un faux-plafond, ce luminaire prévenant tout risque d'endommagement de cette paroi d'habillage.Also, the present invention aims to overcome all or part of these disadvantages by proposing a luminaire, intended to be recessed and held by pressure through a casing wall, such as a false ceiling, this luminaire preventing any risk of damage. damage to this cladding wall.

Le document WO 2011/104258 A2 décrit une lampe intégrée comportant un corps de base et un réflecteur en forme de dôme. La lampe comprend des bras de maintien de la lampe dans une paroi d'habillage avec des extrémités libres munies d'éléments qui augmentent la friction. Le document US 2011/0080733 décrit une lampe comprenant un corps de base et des bras munis d'extrémités libres destinés au maintien de la lampe dans la paroi d'habillage. Chaque extrémité libre comprend un élément formant tampon.The document WO 2011/104258 A2 discloses an integrated lamp comprising a base body and a dome-shaped reflector. The lamp comprises lamp holding arms in a cladding wall with free ends provided with elements which increase the friction. The document US 2011/0080733 discloses a lamp comprising a base body and arms with free ends for holding the lamp in the cladding wall. Each free end includes a buffer member.

A cet effet, la présente invention a pour objet un luminaire, destiné à être encastré et maintenu par pression au-travers d'une paroi d'habillage présentant un trou et deux faces opposées, dont une première face et une deuxième face, le luminaire comprenant un corps principal, une paroi d'appui s'étendant latéralement depuis le corps principal, la paroi d'appui étant destinée à venir en appui contre la première face, et deux ressorts rattachés au corps principal, les ressorts présentant chacun une extrémité libre s'étendant latéralement par rapport au corps principal, au-dessus de la paroi d'appui, chaque ressort exerçant une action de rappel tendant à déplacer son extrémité libre en direction de la paroi d'appui pour prendre en étau la paroi d'habillage avec la paroi d'appui, caractérisé en ce que le luminaire comprend, rattaché à l'extrémité libre de chaque ressort, un organe d'amortissement déformable, destiné à venir en appui contre la deuxième face sous l'action du ressort, en se déformant au contact de la deuxième face afin d'absorber l'énergie cinétique résultant du déplacement de l'extrémité libre du ressort.For this purpose, the subject of the present invention is a luminaire, intended to be recessed and maintained by pressure through a casing wall having a hole and two opposite faces, of which a first face and a second face, the luminaire comprising a main body, a bearing wall extending laterally from the main body, the bearing wall being intended to bear against the first face, and two springs attached to the main body, the springs each having a free end extending laterally relative to the main body, above the support wall, each spring exerting a return action tending to move its free end towards the support wall to grip the cladding wall with the support wall, characterized in that the luminaire comprises, attached to the free end of each spring, a deformable damping member intended to bear against the second face under the action of the spring, deforming in contact with the second face to absorb the kinetic energy resulting from the displacement of the free end of the spring.

Ainsi, le luminaire encastré selon l'invention offre l'avantage de prévenir tout risque d'endommagement de la paroi d'habillage dans laquelle le luminaire est encastré, grâce à l'organe d'amortissement agencé sur chaque ressort pour amortir l'impact par absorption d'énergie cinétique.Thus, the recessed luminaire according to the invention offers the advantage of preventing any risk of damage to the cladding wall in which the luminaire is recessed, thanks to the damping member arranged on each spring to dampen the impact. by kinetic energy absorption.

Selon un mode de réalisation, l'organe d'amortissement comprend une portion de rattachement pour rattacher l'organe d'amortissement à l'extrémité libre du ressort et, sous la portion de rattachement, une portion de déformation destinée à se tasser entre une position de repos dans laquelle la portion de déformation est déployée, et une position d'appui dans laquelle la portion de déformation est comprimée en direction de la portion de rattachement. portion de déformation est comprimée en direction de la portion de rattachement.According to one embodiment, the damping member comprises a connecting portion for reattaching the damping member to the free end of the spring and, under the attachment portion, a portion of deformation intended to settle between a rest position in which the deformation portion is deployed, and a bearing position in which the deformation portion is compressed towards the connecting portion. portion of deformation is compressed towards the connecting portion.

Cette caractéristique offre l'avantage d'une diminution progressive de la pression exercée par les ressorts de torsion sur la deuxième face, l'écrasement de la portion de déformation assurant l'absorption d'énergie cinétique.This characteristic offers the advantage of a progressive decrease in the pressure exerted by the torsion springs on the second face, the crushing of the deformation portion ensuring the absorption of kinetic energy.

Avantageusement, la portion de déformation présente une paroi latérale s'étendant depuis la portion de rattachement, la paroi latérale étant destinée à se déformer radialement lorsque la portion de déformation est écrasée entre la position de repos et la position d'appui.Advantageously, the deformation portion has a lateral wall extending from the attachment portion, the side wall being intended to deform radially when the deformation portion is crushed between the rest position and the support position.

Ainsi, la paroi latérale assure à la fois une résistance à la force exercée par le ressort pour le ralentir et l'immobiliser, tout en amortissant l'impact sur la deuxième face de la paroi d'habillage.Thus, the side wall provides both a resistance to the force exerted by the spring to slow and immobilize, while damping the impact on the second side of the cladding wall.

Selon une caractéristique avantageuse, la portion de déformation comprend, à une extrémité de la paroi latérale, une surface d'appui destinée à venir en appui contre la deuxième face, la superficie de la surface d'appui au contact de la deuxième face étant destinée à augmenter progressivement entre l'instant de l'impact avec la deuxième face et celui de l'immobilisation de l'extrémité libre.According to an advantageous characteristic, the deformation portion comprises, at one end of the lateral wall, a bearing surface intended to bear against the second face, the surface of the bearing surface in contact with the second face being intended to increase gradually between the moment of the impact with the second face and that of the immobilization of the free end.

Ainsi, la surface d'appui, en s'étalant sur la deuxième surface de la portion d'habillage, augmente progressivement la superficie en contact avec cette deuxième face. Or plus la surface est grande, plus faible est la pression.Thus, the bearing surface, spreading over the second surface of the covering portion, gradually increases the area in contact with the second face. But the larger the surface, the lower the pressure.

Avantageusement, la portion de déformation présente, sur la surface d'appui, une rainure d'amortissement.Advantageously, the deformation portion has, on the bearing surface, a damping groove.

Cette rainure d'amortissement procure un meilleur amortissement, en augmentant la surface de contact au moment de l'impact, compte-tenu de la forme hémicylindrique de la portion de déformation.This damping groove provides better damping, by increasing the contact surface at the moment of impact, taking into account the hemicylindrical shape of the deformation portion.

Avantageusement, l'extrémité libre présente deux portions de tige sensiblement parallèles, chaque portion de tige étant agencée au-dessus d'une paroi latérale de la portion de déformation.Advantageously, the free end has two substantially parallel rod portions, each rod portion being arranged above a side wall of the deformation portion.

En d'autres termes, chaque portion de tige étant agencée dans la continuité de la portion de déformation hémicylindrique. Chaque portion de tige s'étend l'un des côtés de la portion de déformation. Ainsi, la portion de déformation offre davantage de résistance à la déformation.In other words, each rod portion being arranged in the continuity of the hemicylindrical deformation portion. Each rod portion extends one side of the deformation portion. Thus, the deformation portion provides more resistance to deformation.

De manière avantageuse, la portion de déformation délimite avec la portion de rattachement une cavité débouchante dont le volume est destiné à diminuer sensiblement entre la position de repos et la position d'appui, en vue d'amortir l'impact.Advantageously, the deformation portion delimits with the attachment portion an opening cavity whose volume is intended to decrease substantially between the rest position and the support position, in order to dampen the impact.

La cavité ou volume intérieur creux favorise un raccourcissement de la distance entre la surface d'appui de la portion de déformation et la portion de rattachement au moment de l'impact, pour un meilleur amortissement.The cavity or hollow interior volume promotes a shortening of the distance between the bearing surface of the deformation portion and the connecting portion at the moment of impact, for better damping.

Selon un mode de réalisation, la cavité présente un orifice débouchant calibré pour autoriser une fuite progressive de l'air contenu dans la cavité au moment de l'impact.According to one embodiment, the cavity has a calibrated opening orifice to allow a gradual leakage of the air contained in the cavity at the moment of impact.

Cela offre l'avantage d'une absorption progressive de l'énergie cinétique des ressorts.This offers the advantage of a gradual absorption of the kinetic energy of the springs.

Selon une possibilité, la portion de déformation délimite avec la portion de rattachement une cavité fermée remplie d'un fluide.According to one possibility, the deformation portion delimits with the attachment portion a closed cavity filled with a fluid.

Le fluide contenu dans l'organe d'amortissement ralentit le tassement de la portion de déformation au moment de l'impact afin de rendre l'amortissement plus progressif. Le fluide peut correspondre à un gaz, par exemple de l'air, ou à un gel ou autre liquide.The fluid contained in the damping member slows the settlement of the deformation portion at the moment of impact in order to make the damping more progressive. The fluid may be a gas, for example air, or a gel or other liquid.

Avantageusement, la portion de déformation est élastique.Advantageously, the deformation portion is elastic.

Ainsi, lorsqu'elle se déforme à l'impact, la portion de déformation tend à revenir à sa forme initiale avant impact, et exerce donc une action s'opposant à celle du ressort, si bien que la portion de déformation autorise un effet de rebond diminuant l'intensité de l'impact sur la paroi d'habillage pour mieux la préserver.Thus, when it deforms on impact, the deformation portion tends to return to its original shape before impact, and therefore exerts an action opposing that of the spring, so that the deformation portion allows a deformation effect. rebound decreasing the intensity of the impact on the cladding wall to better preserve it.

De plus, elle reprend sa forme initiale, c'est-à-dire sa forme avant impact, en cas de démontage du luminaire, ce qui permet une éventuelle réutilisation.In addition, it returns to its original shape, that is to say its shape before impact, in case of disassembly of the luminaire, which allows a possible reuse.

La portion de déformation peut être sensiblement hémicylindrique. La portion de déformation peut être sensiblement sphérique.The deformation portion may be substantially hemicylindrical. The deformation portion may be substantially spherical.

La figure 2 montre un luminaire 1 selon un mode de réalisation de l'invention. Le luminaire 1 est destiné à être encastré et maintenu par pression au-travers d'une paroi 50 d'habillage présentant un trou destiné à l'insertion du luminaire 1, et deux faces opposées, dont une première face 52 et une deuxième face 54. On notera que le luminaire peut correspondre à un spot encastrable.The figure 2 shows a luminaire 1 according to one embodiment of the invention. The luminaire 1 is intended to be recessed and maintained by pressure through a casing wall 50 having a hole intended for the insertion of the luminaire 1, and two opposite faces, of which a first face 52 and a second face 54 It will be noted that the luminaire may correspond to a recessed spot.

La paroi 50 d'habillage peut correspondre à une dalle de faux-plafond. Plus généralement, la paroi 50 d'habillage peut correspondre à un élément en forme de plaque destiné à habiller l'intérieur d'un bâtiment. Par plaque on entend un élément dont l'épaisseur est négligeable par rapport aux autres dimensions (longueur, largeur).The wall 50 covering can be a slab false ceiling. More generally, the covering wall 50 may correspond to a plate-shaped element intended to dress the interior of a building. By plate is meant an element whose thickness is negligible compared to other dimensions (length, width).

Comme cela est visible sur la figure 2, le luminaire 1 comprend un corps 2 principal, une paroi 4 d'appui s'étendant latéralement depuis le corps 2 principal, et deux ressorts 6 rattachés au corps 2 principal.As is visible on the figure 2 , the luminaire 1 comprises a main body 2, a support wall 4 extending laterally from the main body 2, and two springs 6 attached to the main body 2.

Le corps 2 principal, qui peut être de forme sensiblement tronconique, comprend une ouverture de sortie pouvant être sensiblement circulaire, par laquelle s'échappe la lumière émise par une source lumineuse, comme une ou plusieurs diodes électroluminescentes, agencée dans le corps 2 principal afin d'éclairer un espace sous-jacent. Une optique peut être agencée dans l'ouverture de sortie.The main body 2, which may be of substantially frustoconical shape, comprises a substantially circular outlet opening, through which the light emitted by a light source, such as one or more light-emitting diodes, escapes in the main body 2 so to illuminate an underlying space. An optic may be arranged in the exit aperture.

La paroi 4 d'appui est destinée à venir en appui contre la première face 52 de la paroi 50 d'habillage. Elle peut s'étendre en périphérie du corps 2 principal, tout autour de celui-ci, en s'étendant radialement par rapport au corps 2 principal, notamment autour de l'ouverture de sortie. La paroi 4 d'appui peut ainsi former une collerette sensiblement circulaire autour de l'ouverture de sortie du luminaire 1.The support wall 4 is intended to bear against the first face 52 of the wall 50 of dressing. It may extend around the periphery of the main body 2, all around it, extending radially relative to the main body 2, in particular around the outlet opening. The support wall 4 can thus forming a substantially circular collar around the outlet opening of the luminaire 1.

Les ressorts 6 peuvent correspondre à des ressorts en épingle. Ils présentent chacun une extrémité 6a libre, qui peut être formée par une tige repliée sensiblement en forme de U présentant deux portions de tige sensiblement parallèles, l'extrémité 6a libre s'étendant latéralement par rapport au corps 2 principal, au-dessus de la paroi 4 d'appui. Chaque ressort 6 exerce une action de rappel tendant à déplacer l'extrémité 6a libre vers le bas, pour rabattre l'extrémité 6a libre, en forme de tige, en direction de la paroi 4 d'appui, par exemple selon un mouvement de rotation descendant par rapport au corps 2 principal. Les ressorts 6 permettent ainsi de prendre en étau la paroi 50 d'habillage avec la paroi 4 d'appui pour maintenir le luminaire 1 en place dans le trou de la paroi 50 d'habillage. Comme cela est visible sur les figures 2 à 6, les ressorts 6 peuvent correspondre à des ressorts de torsion, et comprendre à cet effet une portion 6b spiralée depuis laquelle s'étend leur extrémité 6a libre, la portion spiralée présentant une portion fixée au corps 2 principal. Les ressorts 6, ici au nombre de deux, peuvent être agencés de façon diamétralement opposée.The springs 6 may correspond to hairpin springs. They each have a free end 6a, which can be formed by a substantially U-shaped folded rod having two substantially parallel rod portions, the free end 6a extending laterally with respect to the main body 2, above the wall 4 support. Each spring 6 exerts a return action tending to move the free end 6a towards the bottom, to fold down the free end 6a, in the form of a rod, in the direction of the support wall 4, for example in a rotational movement descending relative to the main body 2. The springs 6 thus make it possible to grip the cladding wall 50 with the support wall 4 in order to hold the luminaire 1 in place in the hole of the cladding wall 50. As is visible on the Figures 2 to 6 , the springs 6 may correspond to torsion springs, and to this end comprise a spiral portion 6b from which their free end 6a extends, the spiral portion having a portion fixed to the main body 2. The springs 6, here two in number, can be arranged diametrically opposite.

Comme illustré sur la figure 2, le luminaire 1 peut comprendre une paroi 8 de positionnement, s'étendant de façon sensiblement perpendiculaire depuis la paroi 4 d'appui. Cette paroi 8 de positionnement peut être destinée à venir en appui contre la tranche du trou formé dans la paroi 50 d'habillage pour empêcher un déplacement latéral du luminaire 1 dans la paroi 50 d'habillage.As illustrated on the figure 2 , the luminaire 1 may comprise a positioning wall 8, extending substantially perpendicularly from the support wall 4. This positioning wall 8 may be intended to bear against the edge of the hole formed in the wall 50 of covering to prevent lateral displacement of the luminaire 1 in the wall 50 dressing.

Le luminaire 1 peut aussi comprendre un dissipateur 10 thermique, s'étendant à l'arrière du corps 2 principal.The luminaire 1 may also include a heat sink 10 extending at the rear of the main body 2.

On notera que, de façon tout à fait avantageuse, le luminaire 1 comprend, rattaché à l'extrémité 6a libre de chaque ressort 6, un organe 12 d'amortissement déformable, destiné à venir en appui contre la deuxième face 54 de la paroi 50 d'habillage sous l'action de chaque ressort 6, en se déformant au contact de cette deuxième face 54 afin d'absorber l'énergie cinétique résultant du déplacement de l'extrémité 6a libre de chaque ressort 6.It will be noted that, quite advantageously, the luminaire 1 comprises, attached to the free end 6a of each spring 6, a deformable damping member 12 intended to bear against the second face 54 of the wall 50 covering under the action of each spring 6, deforming in contact with the second face 54 to absorb the kinetic energy resulting from the displacement of the free end 6a of each spring 6.

Chaque organe 12 d'amortissement est agencé pour empêcher tout contact entre les ressorts 6 et la deuxième face 54 de la paroi 50 d'habillage lorsque le luminaire 1 est mis en place.Each damping member 12 is arranged to prevent contact between the springs 6 and the second face 54 of the cladding wall 50 when the luminaire 1 is put in place.

Chaque organe 12 d'amortissement peut être en matériau polymère, comme du caoutchouc, naturel ou synthétique, ou du silicone.Each damping member 12 may be of polymeric material, such as rubber, natural or synthetic, or silicone.

Comme illustré sur la figure 3, chaque organe 12 d'amortissement comprend ici une portion 14 de rattachement à l'extrémité 6a libre du ressort et, sous la portion 14 de rattachement, une portion 16 de déformation, qui peut être sensiblement tubulaire. Ainsi, la portion 16 de déformation est interposée entre l'extrémité 6a libre du ressort 6 correspondant et la deuxième face 54.As illustrated on the figure 3 , each damping member 12 here comprises a portion 14 of attachment to the free end 6a of the spring and, under the portion 14 of attachment, a deformation portion 16, which may be substantially tubular. Thus, the deformation portion 16 is interposed between the free end 6a of the corresponding spring 6 and the second face 54.

La portion 16 de déformation est destinée à se tasser entre une position de repos dans laquelle la portion 16 de déformation est déployée, et une position d'appui dans laquelle la portion 16 de déformation est comprimée en direction de la portion 14 de rattachement.The deformation portion 16 is intended to settle between a rest position in which the deformation portion 16 is deployed, and a bearing position in which the deformation portion 16 is compressed in the direction of the portion 14 of attachment.

Comme cela est représenté sur la figure 4, la portion 14 de rattachement peut comprendre un logement 18 d'emmanchement déformable, débouchant sur une ouverture en forme de fente et destiné à recevoir par insertion dans cette ouverture l'extrémité 6a libre du ressort 6 correspondant. La déformation du logement 18 du fait de l'insertion de l'extrémité 6a libre assure le maintien par frottement de celle-ci dans le logement 18.As shown on the figure 4 , the portion 14 of attachment may comprise a deformable fitting housing 18, opening on a slot-shaped opening and intended to receive by insertion into this opening the free end 6a of the corresponding spring 6. The deformation of the housing 18 due to the insertion of the free end 6a ensures the maintenance by friction of the latter in the housing 18.

La portion 14 de rattachement peut aussi être fixé, surmoulée, ou clipsée sur l'extrémité 6a libre du ressort 6 correspondant.The portion 14 of attachment can also be fixed, overmolded or clipped on the free end 6a of the corresponding spring 6.

La portion 16 de déformation peut présenter une paroi 17 latérale s'étendant depuis la portion 14 de rattachement, la paroi 17 latérale étant destinée à se déformer radialement lorsque la portion 16 de déformation est écrasée entre la position de repos et la position d'appui.The deformation portion 16 may have a lateral wall 17 extending from the connecting portion 14, the lateral wall 17 being intended to deform radially when the deformation portion 16 is crushed between the rest position and the support position. .

La portion 16 de déformation peut présenter une surface 20 d'appui destinée à venir en appui contre la deuxième face 54. La portion 16 de déformation est conformée pour se déformer de sorte que la superficie de la surface 20 d'appui au contact de la deuxième face augmente entre l'instant de l'impact avec la deuxième face 54 et celui de l'immobilisation de l'extrémité 6a libre, comme cela est plus particulièrement représenté sur la figure 3.The deformation portion 16 may have a bearing surface 20 intended to abut against the second face 54. The deformation portion 16 is shaped to deform so that the surface of the bearing surface 20 in contact with the second face increases between the moment of the impact with the second face 54 and that of the immobilization of the free end 6a, as is more particularly represented on the figure 3 .

La déformation de la portion 16 de déformation peut être essentiellement radiale, de sorte que la portion 16 de déformation s'écrase avec étalement de la surface 20 d'appui sur la deuxième face 54. Or, plus la surface de contact entre la deuxième face 54 et la surface 20 d'appui est importante, plus faible est la pression.The deformation of the deformation portion 16 may be substantially radial, so that the deformation portion 16 crushes with spreading of the bearing surface on the second face 54. However, the more the contact surface between the second face 54 and the bearing surface is important, the lower is the pressure.

La portion 16 de déformation peut avantageusement être élastique.The portion 16 of deformation may advantageously be elastic.

Comme on peut le voir sur la figure 2, la portion 16 de déformation délimite avec la portion 14 de rattachement une cavité 22, ou un volume intérieur creux, destinée à s'affaisser au moment de l'impact. Par affaissement de la cavité 22 il faut entendre une diminution de la hauteur h de la cavité 22, cette hauteur h pouvant sensiblement correspondre à la distance entre la portion 14 de rattachement et la partie de la portion 16 de déformation la plus éloignée de la portion 14 de rattachement.As can be seen on the figure 2 , the deformation portion 16 delimits with the portion 14 of attachment a cavity 22, or a hollow interior volume, intended to sag at the moment of impact. By subsidence the cavity 22 is to be understood to mean a decrease in the height h of the cavity 22, this height h being able to correspond substantially to the distance between the portion 14 of attachment and the part of the deformation portion 16 furthest from the portion 14 of attachment.

La cavité 22 favorise donc un raccourcissement de la distance entre la surface 20 d'appui de la portion 16 de déformation et la portion 14 de rattachement au moment de l'impact, pour un meilleur amortissement.The cavity 22 thus promotes a shortening of the distance between the bearing surface 20 of the deformation portion 16 and the connecting portion 14 at the moment of impact, for better damping.

La cavité 22 peut le cas échéant être fermée et remplie d'un fluide. Le fluide peut correspondre à de l'air ou à un liquide. Par volume fermé on entend volume non communiquant avec l'extérieur.The cavity 22 may optionally be closed and filled with a fluid. The fluid may be air or a liquid. By closed volume is meant non-communicating volume with the outside.

Selon une autre possibilité, la cavité 22 présente un orifice (non représenté) débouchant calibré pour autoriser une fuite progressive d'un fluide contenu dans la cavité au moment de l'impact.According to another possibility, the cavity 22 has an orifice (not shown) opening calibrated to allow a progressive leakage of a fluid contained in the cavity at the moment of impact.

Comme cela est visible par exemple sur la figure 2, la portion 16 de déformation est sensiblement tubulaire, par exemple hémicylindrique.As is visible for example on the figure 2 the deformation portion 16 is substantially tubular, for example semicylindrical.

L'extrémité 6a libre peut alors présenter deux portions de tige sensiblement parallèles, chaque portion de tige étant agencée dans la continuité de la paroi latérale hémicylindrique de la portion 16 de déformation, comme illustré à la figure 5. En d'autres termes, sous chaque portion de tige s'étend l'un des côtés ou paroi 17 latérale de la portion 16 de déformation, pour une meilleure transmission des efforts.The free end 6a can then have two substantially parallel rod portions, each rod portion being arranged in the continuity of the semicylindrical side wall of the deformation portion 16, as illustrated in FIG. figure 5 . In other words, under each rod portion extends one of the sides or side wall 17 of the deformation portion 16, for a better transmission of forces.

Comme on peut le voir sur les figures 3, 5 et 6, la portion 16 de déformation présente, sur la surface 20 d'appui, une rainure 24 d'amortissement. Cette rainure 24 d'amortissement peut s'étendre sur la partie de la surface 20 d'appui la plus éloignée de la portion 14 de rattachement. Elle peut s'étendre de façon sensiblement parallèle à la direction dans laquelle s'étend la portion 16 de déformation hémicylindrique.As can be seen on the figures 3 , 5 and 6 the deformation portion 16 has a damping groove 24 on the bearing surface. This damping groove 24 may extend over the part of the support surface farthest from the portion 14 of attachment. It can extend substantially parallel to the direction in which the portion 16 of hemicylindrical deformation extends.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit ci-dessus, ce mode de réalisation n'ayant été donné qu'à titre d'exemple. Des modifications sont possibles, notamment du point de vue de la constitution des divers éléments ou par la substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described above, this embodiment having been given as an example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by the substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi, la portion 16 de déformation pourrait être sensiblement sphérique. En d'autres termes, la portion 16 de déformation pourrait correspondre au moins en partie à une boule ou à une sphère.Thus, the deformation portion 16 could be substantially spherical. In other words, the deformation portion 16 could correspond at least in part to a ball or a sphere.
