Abstract

The device (1) has identical parts (4) placed facing each other on sides of a median plane perpendicular to an axle. The parts are embedded with each other by a reciprocal embedding unit (5). Each part has an axial locking projection that cooperates with a circular hole that is provided on the axle. Each part has an axial maintenance cap (8) that is provided in a free end of the part for axial maintenance of the helical spring. The unit (5) cooperates by rotation with one of the parts along a predetermined angle. The cap has an outer diameter greater than an inner diameter of the spring. An independent claim is also included for a motor vehicle seat comprising two elements mounted in rotation with respect to each other, and a device for associating a helical spring on an axle.

Description

2 De la sorte, on obtient une association très ferme du ressort sur l'axe.In this way, a very firm association of the spring on the axis is obtained.

On notera par ailleurs l'absence de sens de montage du dispositif, ce qui évite les erreurs de montage. Enfin, les pièces étant identiques, leur fabrication, notamment par moulage par injection de matière plastique, est particulièrement économique.  Note also the lack of mounting direction of the device, which avoids mounting errors. Finally, the parts being identical, their manufacture, in particular by plastic injection molding, is particularly economical.

Selon un deuxième aspect, l'invention propose un siège de véhicule automobile comprenant deux éléments montés en rotation relative l'un par rapport à l'autre selon un axe, lesdits éléments étant en précontrainte l'un par rapport à l'autre au moyen d'un ressort hélicoïdal, un dispositif selon l'invention étant disposé entre ledit axe et ledit ressort.  According to a second aspect, the invention proposes a motor vehicle seat comprising two elements mounted in relative rotation relative to each other along an axis, said elements being prestressed relative to each other by means of of a helical spring, a device according to the invention being disposed between said axis and said spring.

D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes dans lesquelles : • la figure 1 est une représentation en perspective d'un dispositif selon un mode de réalisation de l'invention, avant emboîtement des pièces entre elles, le ressort hélicoïdal étant prêt à être disposé autour du dispositif, • la figure 2 est une représentation analogue à celle de la figure 1, les pièces étant emboîtées et le dispositif étant monté entre l'axe et le ressort, l'axe étant solidaire d'une armature de siège, • la figure 3 est une vue en coupe longitudinale selon A-A de la figure 2.  Other features and advantages of the invention will become apparent in the description which follows, with reference to the appended figures in which: FIG. 1 is a perspective representation of a device according to one embodiment of the invention, before interlocking the pieces together, the helical spring being ready to be arranged around the device, • Figure 2 is a representation similar to that of Figure 1, the parts being fitted and the device being mounted between the axis and the spring, the axis being integral with a seat frame, • Figure 3 is a longitudinal sectional view along AA of Figure 2.

En référence aux figures, et en premier lieu à la figure 2, on décrit à présent un dispositif 1 d'association d'un ressort hélicoïdal 2 sur un axe 3, ledit dispositif entourant ledit axe et recevant ledit ressort autour de lui, ledit dispositif présentant une forme générale de manchon, ledit dispositif étant formé de deux pièces 4 identiques, visibles sur la figure 1, disposées l'une en regard de l'autre de part et d'autre d'un plan médian perpendiculaire audit axe, lesdites pièces étant emboîtées entre elles par des moyens d'emboîtement réciproques 5, chacune desdites pièces comprenant un moyen de blocage axial 6 destiné à coopérer avec un moyen réciproque 7 prévu sur ledit axe, chacune desdites 3 pièces comprenant en son extrémité libre un moyen de maintien axial 8 dudit ressort.  Referring to the figures, and firstly to FIG. 2, a device 1 for associating a helical spring 2 on an axis 3 is now described, said device surrounding said axis and receiving said spring around it, said device having a general shape of a sleeve, said device being formed of two identical parts 4, visible in FIG. 1, arranged one opposite the other on either side of a median plane perpendicular to said axis, said parts being interlocked with each other by reciprocal engagement means 5, each of said parts comprising an axial locking means 6 intended to cooperate with a reciprocal means 7 provided on said axis, each of said 3 parts comprising at its free end an axial holding means 8 of said jurisdiction.

Selon la réalisation représentée, les moyens d'emboîtement réciproques 5 sont agencés pour pouvoir coopérer par rotation d'une pièce 4 par rapport à l'autre, selon un angle prédéterminé, ici de 90 , par rapport à une disposition desdites pièces en symétrie.  According to the embodiment shown, the reciprocal interlocking means 5 are arranged to cooperate by rotation of a part 4 relative to the other, at a predetermined angle, here 90, relative to an arrangement of said symmetry parts.

Selon la réalisation représentée, le moyen de blocage axial 6 d'une pièce 4 est formé par une saillie issue de sa paroi interne, ladite saillie étant destinée à coopérer avec une tranchée circulaire prévue dans l'axe, ladite tranchée formant moyen de blocage réciproque 7.  According to the embodiment shown, the axial blocking means 6 of a part 4 is formed by a projection coming from its internal wall, said projection being intended to cooperate with a circular trench provided in the axis, said trench forming means of mutual locking 7.

Selon la réalisation représentée, le moyen de maintien axial 8 est formé par une couronne en saillie externe disposée en extrémité de pièce 4, le diamètre externe de ladite couronne étant supérieur au diamètre interne du ressort 2 qu'elle est destinée à maintenir.  According to the embodiment shown, the axial holding means 8 is formed by an outer projecting ring disposed at the end of part 4, the outer diameter of said ring being greater than the internal diameter of the spring 2 that it is intended to maintain.

L'assemblage d'un dispositif 1 se fait en disposant, comme représenté en figure 1, deux pièces 4 l'une en regard de l'autre, un ressort 2 étant disposé entre les deux. Les pièces 4 sont alors emboîtées, par les moyens réciproques 5, de sorte à former le dispositif 1 entouré par le ressort 2. Puis, comme représenté en figure 2, l'ensemble dispositif 1/ressort 2 est enfilé autour de l'axe 3, jusqu'à coopération du moyen de blocage axial 6 avec le moyen réciproque 7, ledit ressort étant mis en contrainte entre deux éléments (un élément 9 est représenté en figure 2) en rotation relative l'un par rapport à l'autre selon ledit axe, par appui de ses extrémités respectives contre lesdits éléments.  The assembly of a device 1 is done by arranging, as shown in Figure 1, two parts 4 one facing each other, a spring 2 being disposed between the two. The parts 4 are then nested, by the reciprocal means 5, so as to form the device 1 surrounded by the spring 2. Then, as shown in Figure 2, the device assembly 1 / spring 2 is threaded about the axis 3 until the axial locking means 6 cooperate with the reciprocal means 7, said spring being stressed between two elements (an element 9 is shown in FIG. 2) in relative rotation relative to each other according to said axis, by pressing its respective ends against said elements.

Un dispositif 1 peut notamment être disposé dans un siège de véhicule automobile comprenant deux éléments 9 montés en rotation relative l'un par rapport à l'autre selon un axe 3, lesdits éléments étant en précontrainte l'un par rapport à l'autre au moyen d'un ressort hélicoïdal 2 entourant ledit axe, ledit dispositif entourant ledit axe et recevant ledit ressort autour de lui.  A device 1 can in particular be arranged in a motor vehicle seat comprising two elements 9 mounted in relative rotation relative to each other along an axis 3, said elements being pre-stressed relative to each other at the by means of a helical spring 2 surrounding said axis, said device surrounding said axis and receiving said spring around it.
