Dans ce qui suit on se référera indifféremment à l'une ou l'autre des figures, sans que ceci soit expressément mentionné.In what follows we will refer indifferently to one or the other of the figures, without this being expressly mentioned.
Le fauteuil conforme à l'invention se compose essentiellement de :The chair according to the invention essentially consists of:
- un dossier (1) ;- a file (1);
- une assise (2) ;- a seat (2);
- un faux châssis (3) ;- a subframe (3);
- un repose-pieds (4) ; - un bâti (5) .- a footrest (4); - a frame (5).
Ces différents éléments sont plus particulièrement visibles aux figures 5A et- 5B.These various elements are more particularly visible in FIGS. 5A and 5B.
Il est destiné à se déplacer entre une pluralité de positions entre la position allongée représentée à la figure 1 et la position de station verticale représentée à la figure 5, en passant par tous les intermédiaires et en particulier la position assise représentée à la figure 4.It is intended to move between a plurality of positions between the lying position shown in FIG. 1 and the vertical station position represented in FIG. 5, passing through all of the intermediaries and in particular the seated position represented in FIG. 4.
Tous ces déplacements et les maintiens en position fixe sont assurés par un vérin unique de commande (6) dont la chape (7) est fixée et articulée sur le bâti (5) en un point (8) situé vers l'avant du fauteuil et dont le couliεseau (9) est relié par une articulation distale en (10) à
un contrefort (11) du dossier (1). ~/ All these movements and maintaining them in a fixed position are ensured by a single control cylinder (6) whose yoke (7) is fixed and articulated on the frame (5) at a point (8) located towards the front of the chair and whose couliεseau (9) is connected by a distal articulation in (10) to a buttress (11) of the backrest (1). ~ /
Le vérin est commandé par un boitier de commande actionné par l'utilisateur, ou un tiers, et assure l'ensemble des différents déplacements. Le mécanisme de commande du repose-pieds est constitué essentiellement de deux biellettes (12,13) et d'un ressort (14).The cylinder is controlled by a control box actuated by the user, or a third party, and ensures all of the different movements. The footrest control mechanism consists essentially of two links (12,13) and a spring (14).
Comme représente à la figure 3, on constate que les biellettes (12,13) sont articulées entre elles en un point (15). Par ailleurs, la biellette de réception de repose-pieds (12) est articulée en (17) sur le cadre (16) formant le repose-pieds (4) tandis qu'à son autre extrémité, la biellette de commande de repose-pieds (13) est articulée en (18) sur une saillie (19) solidaire d'une bielle centrale (20).As shown in Figure 3, we see that the links (12,13) are hinged together at a point (15). Furthermore, the footrest receiving link (12) is articulated at (17) on the frame (16) forming the footrest (4) while at its other end, the footrest control link (13) is articulated at (18) on a projection (19) secured to a central connecting rod (20).
Sur la portée de la biellette (13) est fixée (en 21) la chape du ressort (14) dont la tige (22) est articulée en (23) sur le longeron arrière (24) du dossier.On the bearing surface of the link (13) is fixed (at 21) the yoke of the spring (14) whose rod (22) is articulated at (23) on the rear spar (24) of the backrest.
Le mécanisme de commande de l'assise (2) est constitué essentiellement de trois biellettes (25,26,27) articulées en un point central (28) et qui sont à leurs autres extrémités articulées respectivement : - la biellette (25) de réception sur assise à l'axe frontal (28) de l'assise ;The seat control mechanism (2) essentially consists of three links (25,26,27) articulated at a central point (28) and which are at their other ends articulated respectively: - the reception link (25) on the seat at the front axis (28) of the seat;
- la biellette (26) de commande d'assise en (18) à la partie (19) précitée ;- the seat control link (26) at (18) to the aforementioned part (19);
- la biellette (27) sur le longeron arrière (24) du dossier. Le mécanisme de commande de positionnement du dossier et de maintien du dossier en position verticale se compose essentiellement de :- the link (27) on the rear spar (24) of the backrest. The mechanism for controlling the positioning of the backrest and keeping the backrest in an upright position essentially consists of:
- une bielle central (20) ;- a central connecting rod (20);
- deux biellettes (29,30).- two links (29,30).
La bielle centrale (20) est articulée à l'une de ses extrémités (31) sur le bâti (5) et à son autre extrémité en un point (32) aux deux biellettes (29,30).The central connecting rod (20) is articulated at one of its ends (31) on the frame (5) and at its other end at a point (32) with the two connecting rods (29,30).
A son autre extrémité la biellette (29) est articulée en (33) sur le faux-chassis (3).At its other end, the link (29) is articulated at (33) on the subframe (3).
A son autre extrémité, la biellette (30) est articulée en (34) sur le longeron arrière (24) du dossier.
Le faux-chassis (3) comporte une butée mécanique (35) disposée sensiblement perpendiculairement à celui-ci et qui vient en butée, de la position assise jusqu'à la position allongée contre un longeron horizontal (36) du bâti. Le ressort (14) qui maintient le repose-pieds en position déployée se transforme, à partir de la position d'extension maximale du coulisseau en biellette rigide.At its other end, the link (30) is articulated at (34) on the rear spar (24) of the backrest. The subframe (3) comprises a mechanical stop (35) disposed substantially perpendicular thereto and which comes into abutment, from the seated position to the lying position against a horizontal beam (36) of the frame. The spring (14) which keeps the footrest in the deployed position is transformed, from the position of maximum extension of the slide into a rigid link.
Enfin, le repose-pieds est articulé en (37) par rapport à l'assise. On comprendra que l'on a représenté et décrit que les éléments essentiels à la compréhension cinématique de l'invention. Les autres éléments fonctionnels sont accessibles à l'homme de l'art.
Finally, the footrest is articulated in (37) relative to the seat. It will be understood that the essential elements for the kinematic understanding of the invention have been shown and described. The other functional elements are accessible to those skilled in the art.
