Abstract

Some existing seats comprise a structure that allows users to stretch out their legs; however, these types of seats are not provided with stowable telescopic sliding extension systems upholstered with substantially isometric fabric. The invention concerns a seating and/or reclining furniture item that comprises a telescopic sliding extension system (5) upholstered with resilient and substantially isometric composite fabric (12), said system being capable of being moved between a non-use position in which it is stowed inside the seat (2) and a use position in which it projects towards the front of the seat. With the seat back (3) lowered and the extension (5) extended, the device is capable of forming an item of relaxation furniture. The device according to the invention is intended for improving the comfort of seating and/or reclining furniture.

En référence à ces dessins, le meuble d'assise et/ou de couchage à rallonges selon ia présente invention est formé essentiellement par un piétement (1), une assise (2), un dossier (3), des accoudoirs (4) articulés, un système de rallonges coulissantes télescopiques (5) et éventuellement un système de réglage de la hauteur du siège par vérin à gaz (17). Selon la présente invention, la rallonge (S) de l'assise (2) est extraite de l'intérieur de l'assise (2) en tirant sur la poignée (20) située sous l'avant du système de rallonges (5). Une butée de fin de course (18) fixée au châssis (10) de l'assise (2) empêche la rallonge (5) de quitter entièrement le châssis (10) de l'assise (2). Les deux pieds (9) articulés à charnières montés sous la rallonge (5) sont reliés par une traverse (21) et se déploient ensemble pour soutenir la rallonge (5) dans sa position d"utilisation, le dossier (3) articulé à pivot s'incline selon un angle variable et se bloque en actionnant la poignée de serrage (15) et le bouton dé réglage (16) du support télescopique (6) articulé à pivot fixé au dossier (3) ainsi que le frein de la roulette (8) du support télescopique (6). Une fois la rallonge (5) extraite et le dossier (3) articulé à pivot abaissé, le dispositif se trouve en capacité de former un meuble de relaxation. With reference to these drawings, the extending bedding and / or sleeping furniture according to the present invention is essentially formed by a base (1), a seat (2), a backrest (3), articulated armrests (4). , a system of telescopic sliding extensions (5) and possibly a system for adjusting the height of the seat by gas cylinder (17). According to the present invention, the extension (S) of the seat (2) is extracted from the inside of the seat (2) by pulling on the handle (20) located under the front of the extension system (5) . A limit stop (18) fixed to the frame (10) of the seat (2) prevents the extension (5) completely leave the frame (10) of the seat (2). The two hinged legs (9) hinged under the extension (5) are connected by a crossmember (21) and deploy together to support the extension (5) in its position of use, the backrest (3) articulated pivot tilts at a variable angle and locks by actuating the clamping handle (15) and the adjusting knob (16) of the telescopic support (6) pivotally attached to the backrest (3) and the brake of the wheel ( 8) of the telescopic support (6) Once the extender (5) extracted and the backrest (3) hinged down pivot, the device is in the capacity to form a relaxation cabinet.
Les accoudoirs (4) peuvent être rabattus pour faciliter l'accès de l'invention.  The armrests (4) can be folded down to facilitate access of the invention.
Quand la présente invention est en mode "siège", le support télescopique (6) articulé à pivot fixé au dossier (3) peut s'escamoter en partie (voir fig. 8) en appuyant sur le bouton de réglage (16) qui permet de faire coulisser la partie mâle (22) dans la partie femelle du support télescopique (6). En relâchant le bouton de réglage (16) au niveau d'un des trous (24) qui percent graduellement la partie mâle (22), un ressort (23) permet de maintenir le support télescopique bloqué à la longueur voulue. When the present invention is in "seat" mode, the pivotally articulated telescopic support (6) fixed to the backrest (3) can partially retract (see Fig. 8) by pressing the adjustment button (16) which allows to slide the male part (22) into the female part of the telescopic support (6). By releasing the adjustment knob (16) at one of the holes (24) which gradually pierce the male portion (22), a spring (23) keeps the telescopic support locked to the desired length.
En cas de non-utilisation de la rallonge (5) de l'assise (2), un aimant (19) permet de maintenir'Ja ou les rallonges (5) rangées à l'intérieur de l'assise (2). Un autre aimant permet de maintenir le support télescopique (6) contre le dossier (3).  In case of non-use of the extension (5) of the seat (2), a magnet (19) keeps'Ja or extensions (5) stored inside the seat (2). Another magnet holds the telescopic support (6) against the backrest (3).
L'assise (2) de la présente invention comprend un châssis (10) partiellement  The seat (2) of the present invention comprises a frame (10) partially
recouvert de mousse (11) enrobée de tissu ainsi que d'une toile composite résïliente quasiment isométrique (12).  coated with foam (11) coated with fabric and a substantially isometric composite resin fabric (12).
Les rallonges (5, 26) de la présente invention sont composées d'un plateau (14) reliant deux montants (13) formant saillies sur lesquels est fixée une toile composite résiliente quasiment isométrique (12).  The extensions (5, 26) of the present invention are composed of a plate (14) connecting two uprights (13) forming projections on which is fixed a substantially isometric resilient composite cloth (12).
