Description

-La présente invention concerne un dispositif pour augmenter la hauteur du dossier d'un canapé, afin d'accroître le confort et permettre un bon maintien cervical. -Seul des systèmes mécaniques soit par moteurs électriques, soit par vérins 5 hydrauliques, ou soit par ajout d'appui-têtes (type appui-tête automobile) existent sur le marché actuellement. -Le dispositif selon l'invention permet d'augmenter la hauteur du dossier avec un moyen simple et efficace : la rotation du cale-reins. Le coussin de cale-reins est maintenu au coussin de dossier par une fermeture éclair, qui permet 10 la rotation du cale-reins, voire tout autre moyen de fixation. En position repliée, le cale-reins se positionne derrière le coussin de dossier, avançant légèrement la profondeur de l'assise. En position déployée, le cale-reins se situe sous le coussin de dossier, sur élevant la hauteur de celui-ci et augmentant la profondeur d'assise. Le coussin de dossier repose sur le haut 15 de la structure du dossier. La fermeture éclair permet la rotation aisée du cale-reins pour passer d'une position à l'autre très simplement. -Les dessins et photos annexés illustrent l'invention : La figure 1-A / page 1 sur 6 représente la photo de face du dossier en position 20 baissée. La figure 2-A / page 1 sur 6 représente la photo de face du dossier en position relevée. La figure 1-B / page 2 sur 6 représente le croquis du dossier (1) en position baissée.The present invention relates to a device for increasing the height of the back of a sofa, to increase comfort and allow good cervical support. Only mechanical systems, either by electric motors, or by hydraulic cylinders, or by the addition of headrests (headrest type), exist on the market today. The device according to the invention makes it possible to increase the height of the backrest with a simple and effective means: the rotation of the wedge-kidneys. The wedge-back cushion is held in the back cushion by a zipper, which allows rotation of the kidney block, or even any other means of attachment. In the folded position, the backrest is positioned behind the back cushion, slightly moving the depth of the seat. In the deployed position, the backrest is located under the back cushion, raising the height of the latter and increasing the seat depth. The back cushion rests on the top 15 of the backrest structure. The zipper allows easy rotation of the kidney-shim to move from one position to another very simply. The accompanying drawings and photos illustrate the invention: FIG. 1-A / page 1 of 6 shows the front view of the backrest in lowered position. Figure 2-A / Page 1 of 6 shows the front view of the backrest in raised position. Figure 1-B / Page 2 of 6 shows the sketch of the backrest (1) in the down position.
