Description

La présente invention se rapporte à un meuble utilisé pour s'asseoir ou pour s'étendre, notamment un fauteuil, une chaise, un canapé, un lit ou analogue comportant un élément, notamment une têtière, pouvant passer entre deux positions et/ou deux états, ainsi qu'à un ensemble comportant un meuble utilisé pour s'asseoir ou pour s'étendre, notamment un fauteuil, une chaise, un canapé, un lit ou analogue et un élément pouvant passer entre deux positions et/ou deux états, l'élément étant distinct du meuble, par exemple l'élément pouvant être une porte de meuble de télévision, à distance du canapé, une télévision, un système de sonorisation, une porte de bar, une table mobile, etc.The present invention relates to a furniture used to sit or to extend, including an armchair, a chair, a sofa, a bed or the like comprising an element, including a headrest, which can pass between two positions and / or two states, and an assembly comprising a piece of furniture used to sit or to extend, including an armchair, a chair, a sofa, a bed or the like and an element that can pass between two positions and / or two states, the element being distinct from the piece of furniture, for example the element that can be a television cabinet door, away from the sofa, a television, a sound system, a bar door, a mobile table, etc.

On connaît déjà dans l'art antérieur des canapés comportant une têtière montée de manière à pouvoir pivoter entre deux ou plusieurs positions, notamment une position abaissée et une position relevée, dans laquelle elle soutient la tête de la personne assise sur le canapé. Il est aussi connu de prévoir un système pour commander le déplacement de la têtière entre les deux positions relevée et abaissée, à savoir un système électrique qui commande l'activation/désactivation d'un moteur électrique entraînant un système mécanique lié à la têtière. L'utilisateur, lorsqu'il veut mettre la têtière dans la position dans laquelle elle supporte sa tête, commande, notamment par l'intermédiaire de boutons de commande, l'actionnement du moteur, ce qui entraîne en rotation la têtière jusqu'à la position relevée souhaitée. Ces canapés de l'art antérieur sont assez compliqués à utiliser, et notamment l'utilisateur doit, chaque fois qu'il s'assoit, régler la têtière dans la position appropriée dont il a envie, notamment en maintenant appuyé un bouton, puis, lorsqu'il quitte le canapé, il doit rabaisser la têtière dans sa position abaissée ou de repos, pour éviter que le système mécanique lié à la têtière ne soit détérioré par ur choc ou autre, le système mécanique n'étant pas, lorsque la têtière se trouve en position relevée, protégé d'une manière aussi sûre que lorsqu'elle est en position abaissée. En effet, dans la position abaissée, le système mécanique de déplacement de la têtière n'apparaît pas à l'extérieur et est donc protégé.Already known in the prior art sofas having a headrest mounted so as to pivot between two or more positions, including a lowered position and a raised position, in which it supports the head of the person sitting on the couch. It is also known to provide a system for controlling the movement of the headrest between the two raised and lowered positions, namely an electrical system that controls the activation / deactivation of an electric motor driving a mechanical system connected to the headrest. The user, when he wants to put the headrest in the position in which it supports its head, controls, in particular via control buttons, the actuation of the motor, which causes rotation of the headrest to the desired raised position. These sofas of the prior art are quite complicated to use, and in particular the user must, each time he sits, adjust the headrest in the appropriate position he wants, including holding a button, then, when he leaves the sofa, he must lower the headrest in its lowered or rest position, to prevent the mechanical system connected to the headrest from being damaged by shock or otherwise, the mechanical system not being, when the headrest is in the raised position, also protected sure when in the lowered position. Indeed, in the lowered position, the mechanical system of movement of the headrest does not appear outside and is therefore protected.

Un siège d'auto avec têtière est connu de US2012032487 .A car seat with headrest is known to US2012032487 .

La présente invention vise à surmonter les inconvénients de l'art antérieur en proposant un meuble utilisé pour s'asseoir ou s'allonger, notamment un fauteuil, une chaise, un lit ou un canapé, qui surmonte les inconvénients de l'art antérieur, et en particulier qui est très simple d'utilisation, et dont le système de commande de l'élément pouvant prendre deux positions ou états, par exemple le système de déplacement de la têtière, a une longue durée de vie.The present invention aims to overcome the disadvantages of the prior art by providing a furniture used to sit or lie down, including an armchair, a chair, a bed or a sofa, which overcomes the disadvantages of the prior art, and in particular which is very easy to use, and whose control system of the element can take two positions or states, for example the system of movement of the headrest, has a long life.

Selon l'invention, un meuble utilisé pour s'asseoir ou s'allonger, notamment un fauteuil, une chaise, un lit ou un canapé est tel que défini à la revendication 1.According to the invention, a piece of furniture used to sit or lie down, in particular an armchair, a chair, a bed or a sofa, is as defined in claim 1.

Des perfectionnements et modes de réalisation avantageux sont définis aux sous revendications 2 à 7.Advantages and advantageous embodiments are defined in Claims 2 to 7.

A titre d'exemple, on décrit maintenant des modes de réalisation préféré de l'invention en se reportant aux dessins, dans lesquels :

By way of example, preferred embodiments of the invention will now be described with reference to the drawings, in which:
Figure 1
is a perspective view of a sofa according to the invention;
Figure 2
is a side view of the couch of the figure 1 ;

Figure 5
is a perspective view of the sofa Figures 1 to 4 ; and
Figure 6
is a perspective view showing a set according to the invention, comprising a sofa and a television, arranged to be viewed from the sofa.

Aux figures 1 à 5, il est représenté un canapé à deux places comprenant un bâti 1 comportant d'une part une partie d'assise 2, sur laquelle sont disposés deux coussins 3 et 4 formant deux places sur lesquelles une ou des personnes peuvent s'asseoir, et d'autre part une partie formant dossier 9 contre lequel sont positionnés deux coussins 5 et 6 pour supporter le dos des personnes assises respectivement sur les coussins 3, 4 de la partie d'assise 2.To the Figures 1 to 5 , there is shown a two-seater sofa comprising a frame 1 having on the one hand a seat portion 2, on which are arranged two cushions 3 and 4 forming two seats on which one or persons can sit, and part of it forming backrest 9 against which are positioned two cushions 5 and 6 to support the back of the persons sitting respectively on the cushions 3, 4 of the seat part 2.

En outre, une têtière 7 (une seule têtière est représentée aux figures pour la place de gauche sur le canapé, sachant que l'on peut également prévoir une têtière pour l'autre place ou une têtière commune aux deux places) est montée au dessus du dossier 9 de manière à pouvoir pivoter par rapport au bord supérieur de ce dernier, entre une position abaissée dans laquelle elle est sensiblement à l'horizontale en reposant sur le bord supérieur du dossier 9 et une position relevée inclinée vers le haut, notamment d'un angle qui peut être compris notamment entre 0 et 120°, de préférence entre environ 40 à 60° comme représenté à la figure 4, dans laquelle elle est de préférence sensiblement en continuité avec l'inclinaison du coussin 6 de dossier.In addition, a headrest 7 (a single headrest is shown in the figures for the left seat on the sofa, knowing that one can also provide a headrest for the other place or headrest common to both places) is mounted above of the backrest 9 so as to be pivotable with respect to the upper edge of the latter, between a lowered position in which it is substantially horizontal while resting on the upper edge of the backrest 9 and a raised position inclined upwards, in particular d an angle which can be in particular between 0 and 120 °, preferably between approximately 40 and 60 ° as shown in FIG. figure 4 , in which it is preferably substantially in continuity with the inclination of the backrest cushion 6.

Le canapé comporte en outre deux accoudoirs 8 et 10 gauche et droite. Dans l'accoudoir 10, il est logé un système électrique 19 de commande, notamment à l'aide de circuits intégrés bien connus dans le domaine, qui est relié à un moteur 20 électrique incorporé dans le dossier qui entraîne le système mécanique lié à la têtière pour faire pivoter cette dernière entre ses deux positions abaissée et relevée et vice-versa. Ce système de commande de têtière par moteur électrique est bien connu dans le domaine et n'est pas décrit plus en détail ci-dessous. Il est prévu de pouvoir mémoriser plusieurs positions de têtière en fonction de chaque utilisateur, notamment en fonction du poids de l'utilisateur.The sofa also has two armrests 8 and 10 left and right. In the armrest 10, there is housed an electrical control system 19, in particular using integrated circuits well known in the field, which is connected to an electric motor 20 incorporated in the backrest which drives the mechanical system linked to the headrest to rotate the latter between its two positions lowered and raised and vice versa. This electric motor headrest control system is well known in the art and is not described in more detail below. It is expected to memorize several headrest positions according to each user, in particular according to the weight of the user.

Entre l'assise 2 et le coussin 4, il est monté un capteur 11 de pression destiné à capter la pression appliquée sur le coussin 4, notamment le poids d'une personne s'asseyant sur le coussin 4. Ce système de capteur est bien connu dans le domaine et n'est pas décrit plus en détail. Il est relié électriquement au système de commande électrique incorporé dans l'accoudoir. Suivant un autre mode de réalisation, plus simple et ne comportant pas de système de commande intégré à l'accoudoir, on peut prévoir qu'il soit directement relié au moteur d'entraînement de la têtière. On peut également prévoir une combinaison de ces deux modes de réalisation.Between the seat 2 and the cushion 4, he mounted a pressure sensor 11 for sensing the pressure applied to the cushion 4, including the weight of a person sitting on the cushion 4. This sensor system is well known in the art and is not described in more detail. It is electrically connected to the electric control system incorporated in the armrest. According to another embodiment, simpler and having no integrated control system to the armrest, it can be provided that it is directly connected to the drive motor of the headrest. It is also possible to provide a combination of these two embodiments.

En position de non utilisation du canapé (c'est à dire qu'il n'y a personne d'assis sur la partie d'assise), la têtière repose à plat sur le bord supérieur du dossier 9 du canapé. Lorsqu'une personne s'assoit sur le coussin 4, le capteur de pression détecte la présence de la personne sur le canapé, et notamment son poids. Le capteur de pression transmet alors un signal au système électronique de commande intégré dans l'accoudoir par l'intermédiaire de fils conducteurs électriques ou par une technologie sans fil, par exemple par ondes HF. A la réception du signal, le système de commande actionne le moteur pour qu'il entraîne le système mécanique lié à la têtière, pour amener la têtière en position relevée dans laquelle elle supporte la tête de l'utilisateur assis sur la partie d'assise.In the non-use position of the sofa (that is, there is no one sitting on the seat part), the headrest rests flat on the upper edge of the backrest 9 of the sofa. When a person sits on the cushion 4, the pressure sensor detects the presence of the person on the sofa, including its weight. The pressure sensor then transmits a signal to the electronic control system integrated in the armrest via electrical conductors or by wireless technology, for example by RF waves. Upon receipt of the signal, the control system actuates the motor to drive the mechanical system connected to the headrest, to bring the headrest in raised position in which it supports the head of the user sitting on the seat part .

Lorsque la personne quitte le canapé, le capteur de pression détecte ce fait et, par exemple soit immédiatement, soit au bout d'un certain intervalle de temps donné à l'avance, transmet un signal correspondant au système électronique de commande qui actionne alors le moteur pour que ce dernier entraîne dans l'autre sens la têtière pour la ramener en position abaissée contre le bord supérieur du dossier.When the person leaves the couch, the pressure sensor detects this fact and, for example either immediately or after a certain time interval given in advance, transmits a signal corresponding to the electronic control system which then actuates the motor for the latter to drive the headrest in the other direction to bring it back into the lowered position against the edge upper folder.

Ainsi, le système suivant l'invention est particulièrement simple d'utilisation, puisque l'utilisateur n'a plus à agir, soit manuellement sur la têtière, soit en appuyant sur des boutons, pour positionner la têtière lorsqu'il s'assoit sur le canapé, la têtière se mettant en position de support de tête d'elle-même sans que l'utilisateur n'ait rien à faire. En outre, lorsque l'utilisateur quitte le canapé, il n'a pas besoin non plus de ramener la têtière en position abaissée, ce qu'il a souvent tendance à oublier de faire dans les systèmes de l'art antérieur, ceci prenant beaucoup de temps. Il en résulte que la têtière est plus souvent au cours de sa vie en position abaissée, position qui est préférable pour que la durée de vie du système mécanique d'entraînement de la têtière soit prolongée. En effet, en position relevée, le système mécanique est plus susceptible d'être détérioré, par exemple par un choc.Thus, the system according to the invention is particularly simple to use, since the user no longer has to act, either manually on the headrest, or by pressing buttons, to position the headrest when it sits on the sofa, the headrest putting itself in the head support position of itself without the user having anything to do. In addition, when the user leaves the couch, he also does not need to bring the headrest down, which he often tends to forget to do in the systems of the prior art, this taking a lot of time. As a result, the headrest is more often during its life in the lowered position, a position which is preferable for the life of the mechanical drive system of the headrest is extended. Indeed, in the raised position, the mechanical system is more likely to be damaged, for example by a shock.

Suivant un mode de réalisation préféré de l'invention, on peut également mémoriser dans le système de commande électronique du moteur électrique des positions préréglées de la position relevée de la têtière, de sorte que, lorsqu'une personne s'assoit, les signaux envoyés par le capteur déclenche le moteur pour qu'il amène la têtière dans une des positions préenregistrées en fonction du poids de la personne ou dans la dernière position mémorisée, permettant ainsi pour chaque occupant de la maison d'avoir à disposition une position préréglée de la têtière qui lui convient de manière automatique.According to a preferred embodiment of the invention, it is also possible to memorize in the electronic control system of the electric motor preset positions of the raised position of the headrest, so that, when a person sits, the signals sent by the sensor triggers the motor to bring the headrest into one of the prerecorded positions according to the weight of the person or in the last stored position, thus allowing for each occupant of the house to have available a preset position of the headrest that suits him automatically.

Suivant encore un autre mode de réalisation, on peut également prévoir des moyens qui bloquent automatiquement le moteur et donc la rotation de la têtière lorsque la têtière vient en contact avec la tête de l'utilisateur, pour ainsi prendre sa position relevée finale.According to yet another embodiment, it is also possible to provide means which automatically block the motor and therefore the rotation of the headrest when the headrest comes into contact with the user's head, thus to take its final raised position.

Suivant un mode de réalisation, le système mécanique lié à la têtière n'apparaît à l'extérieur que dans la position relevée de la têtière.According to one embodiment, the mechanical system connected to the headrest appears on the outside only in the raised position of the headrest.

Suivant un autre mode de réalisation, le système mécanique lié à la têtière n'apparaît pas à l'extérieur dans aucune des positions de la têtière.According to another embodiment, the mechanical system connected to the headrest does not appear outside in any of the positions of the headrest.

A la figure 6, il est représenté le canapé de la figure 1 en combinaison avec un élément à distance du canapé, à savoir une télévision T. Lorsque le capteur de présence détecte la présence d'une personne assise sur la partie d'assise, il transmet un signal au système électronique de commande du commutateur de la télévision de préférence par une technologie sans fil, notamment HF. A la réception du signal, le système électronique de commande fait passer le commutateur initialement dans sa position fermée (télévision éteinte) à sa position ouverte (télévision allumée). On obtient ainsi un ensemble particulièrement simple d'utilisation. On peut envisager tout autre ensemble du même genre, d'une part un meuble sur lequel on s'assoit ou s'allonge et d'autre part un élément qui prend alors une position ou un état d'utilisation, différent de sa position ou état d'attente. De même, lorsque le capteur détecte l'absence d'une personne au bout d'un certain temps donné à l'avance et réglable au choix de l'utilisateur, le capteur envoie un signal au système électronique pour renvoyer la télévision dans son état éteint précédent.To the figure 6 , he is represented the couch of the figure 1 in combination with an element at a distance from the sofa, namely a television T. When the presence sensor detects the presence of a person sitting on the seat part, it transmits a signal to the electronic control system of the television switch. preferably by wireless technology, especially HF. Upon receipt of the signal, the electronic control system switches the switch initially in its closed position (television off) to its open position (television on). This gives a particularly simple set of use. One can consider any other set of the same kind, on the one hand a piece of furniture on which one sits or lies down and on the other hand an element which then takes a position or a state of use, different from its position or waiting state. Similarly, when the sensor detects the absence of a person after a certain time in advance and adjustable to the user's choice, the sensor sends a signal to the electronic system to return the television to its state off previous.

Ainsi, le système suivant l'invention est particulièrement simple d'utilisation, puisque l'utilisateur n'a plus à agir, soit manuellement sur la télévision, soit en appuyant sur des boutons, pour allumer la télévision lorsqu'il s'assoit sur le canapé, la télévision s'allumant d'elle-même sans que l'utilisateur n'ait rien à faire. En outre, lorsque l'utilisateur quitte le canapé, il n'a pas besoin non plus d'éteindre la télévision, ce qu'il a souvent tendance à oublier de faire dans les systèmes de l'art antérieur, ceci prenant beaucoup de temps. Il en résulte que la télévision est plus souvent au cours de sa vie à l'état éteint, état qui est préférable pour que sa durée de vie soit prolongée.Thus, the system according to the invention is particularly simple to use, since the user no longer has to act, either manually on the television, or by pressing buttons, to turn on the television when he sits on the couch, the television lighting up of itself without the user having anything to do . In addition, when the user leaves the couch, he also does not need to turn off the television, which he often tends to forget to do in the systems of the prior art, this taking a lot of time . As a result, television is more often during its life in the off state, a state that is preferable for its lifetime to be prolonged.
