Abstract

The invention relates to foldable seats of the "deckchair" type, the articulation principle of which makes it possible to avoid any untimely collapse. It comprises an internal part 2 articulated on an external part 1, both of which are held in position by a crossbeam 4 which is integral with two struts 3 articulated on the part 1 within notches 8, whose profile limits at 9 the clearance of the struts 3 in order to limit the inclination of the part 1. The part 1 bears articulation pivots 6 which can slide within the slideways 5 provided in the part 2, which makes it possible to collapse the seat by tilting the part 1 forward and sliding it in the reverse direction along the part 2. Its safety makes the invention particularly advantageous for use by children.

Description

La présente invention concerne les sièges pliant du type "ehais-lonOue" ou "transatlantique", réglables en inclinaison. The present invention relates to folding seats of the "ehais-lonOue" or "transatlantic" type, adjustable in inclination.

Les systèmes connus de ce genre sont essentiellement constitués de deux parties articulées entre elles suivant un axe passant par leurs plans respectifs et maintenues en position d'utilisation et en inclinaison par un dispositif articulé sur l'une et reposant en des points variables sur l'autre. Ce dispositif est généralement constitué par deux jambes de force, articulées sur le dossier, reliées par une traverse prenant appui sur le partie opposée formant le jambage arrière. Les jambes de force ont une longueur telle qu'elles puissent titre relevées le long du dossier, étant disposées à l'extérieur de celui-ci, lors del'opération de repliement du siège qui se fait en poursuivant l'inclinaison de la sertie formant dossier jusqu'a ce quelle se trouve dans le mtme plan que l'autre partie. Known systems of this kind essentially consist of two parts hinged together along an axis passing through their respective planes and maintained in the position of use and in inclination by a device articulated on one and resting at variable points on the other. This device generally consists of two struts, articulated on the backrest, connected by a crosspiece bearing on the opposite part forming the rear jamb. The struts have a length such that they can title raised along the backrest, being arranged outside of it, during the folding operation of the seat which is done by continuing the inclination of the seam forming file until it is in the same plane as the other party.

Un tel système est dangereux car le dispositif qui règle la position et l'inclinaison peut glisser de façon intempestive le long du jambage arrière s'il est mal posé sur les encoches qui lui servent d'appui, ou lors d'un accrochage ou d'une manoeuvre maladroite, provoquant l'affaissement brutal du siège. En outre, pendant les manipulations, les montants du siège fonctionnent à la manière de ciseaux, ce qui est particulièrement dangereux lorsqu'il est utilisé par de jeunes enfants. Such a system is dangerous because the device which regulates the position and the inclination can slip inadvertently along the rear jamb if it is incorrectly placed on the notches which serve as its support, or during a hooking or '' an awkward maneuver, causing the seat to collapse suddenly. In addition, during handling, the seat posts work in the manner of scissors, which is particularly dangerous when used by young children.

Le siège selon l'invention permet d'éviter ces inconvé- nient En effet l'inclinaison maxima du dossier est limite, de telle façon qu'elle rend impossible son basculement complet vers l'arrière, évitant un affaissement brutal du siège. The seat according to the invention makes it possible to avoid these drawbacks. In fact, the maximum inclination of the backrest is limited, in such a way that it makes it impossible for it to tilt completely backwards, avoiding sudden collapse of the seat.

La limitation de l'inclinaison est obtenue par le montage des jambes de force qui sont articulées a' à de mortaises pratiquées dans l'épaisseur des montants du dossier. Leur débattement est limité par le profil même de la mortaise sur lequel elles viennent buter. Cette disposition a s antage d'éviter totalement l'effet de ciseau décrit plus haut. The limitation of the inclination is obtained by mounting the struts which are articulated to mortises made in the thickness of the uprights of the backrest. Their travel is limited by the very profile of the mortise on which they come up against. This arrangement has the advantage of completely avoiding the scissor effect described above.

Le dispositif selon l'invention ayant pour objet de rendre impossible l'inclinaison totale du dossier vers l'arrière le repliement ne peut plus s'effectuer par basculement dans ce sens. ne solution est apportée en faisant basculer vers l'avant la partie formant dossier et en la faisant ensuite coulisser en sens oppose jusqu' ce que l'autre partie vienne se loger entre ses montants. Le coulissement est obtenu par l'action des pivots d'articulation du siège, fixés sur l'une des parties, qui peuvent se déplacer à l'intérieur de glissières pratiquées dans les montants de l'autre partie. The device according to the invention having as an object to make impossible the total tilting of the backrest the folding can no longer be done by tilting in this direction. no solution is provided by tilting the part forming the back forward and then sliding it in the opposite direction until the other part comes to lodge between its uprights. The sliding is obtained by the action of the articulation pivots of the seat, fixed on one of the parts, which can move inside slides made in the uprights of the other part.

En position d'utilisation, les pivots viennent buter sur extrmité des glissières située vers l'axant du siège.In the position of use, the pivots abut on the end of the slideways located towards the axis of the seat.

Les pivots d'articulation du siège sont prévus pour être fixés sur la partie formant dossier et les glissières aménagées sur l'autre partie. Mais il est également possible de fixer les pivots sur la partie inférieure formant jambage arrière1 les glissières étant alors aménagées sur la partie formant dossier. The seat articulation pivots are designed to be fixed on the part forming the backrest and the slides fitted on the other part. But it is also possible to fix the pivots on the lower part forming the rear jamb1, the slides then being arranged on the part forming the backrest.

Le dessin annexé est une vue perspective 3/4 arrière. The accompanying drawing is a rear 3/4 perspective view.

Tel qu'il est représenté sur la figure 1, le siège comporte une partie formant jambage arrière 2 articulée sur une partie formant dossier 1 et à l'intérieur de celle-ci au moyen des pivots 6, maintenues en position par une traverse 4 solidaire de deux jambes de force 3 articulées en 7 à 1' intérieur de mortaises 8. La partie formant jambage arrière 2 comporte deux glissières 5 dans lesquelles peuvent coulisser les pivots 6. As shown in Figure 1, the seat has a rear leg portion 2 hinged on a back portion 1 and inside thereof by means of pivots 6, held in position by a cross 4 integral of two struts 3 articulated at 7 inside the mortises 8. The rear jamb part 2 comprises two slides 5 in which the pivots 6 can slide.

La figure 2 représente le détail de l'articulation en 7 des jambes de force 3 à l'intérieur des mortaises 8 prati quées sur les montants de la partie formant dossier 1. En position d'inclinaison maxima la jambe de force 3 vient buter sur le bord 9 de la mortaise 8, ce qui limite son débat tement. FIG. 2 shows the detail of the articulation in 7 of the struts 3 inside the mortises 8 practiced on the uprights of the part forming the backrest 1. In the position of maximum inclination the strut 3 abuts on the edge 9 of the mortise 8, which limits its debate.

Le siège objet de l'invention peut entre utilisé dans tous les cas où il est nécessaire d'avoir un siège repliable et réglable1 facilement transportable. Sa sécurité le rend particulièrement intéressant pour être utilisé par des enfants.  The object of the invention seat can be used in all cases where it is necessary to have a foldable and adjustable seat1 easily transportable. Its safety makes it particularly interesting to be used by children.
