Definitions

  • the present invention consists of a new perfected stackable chair, molded of any one-piece plastic material, with a backrest height greater than those existing in the market. In addition, it has rear and side reinforcements that allow this upper backrest height, avoiding problems that may arise from it.
  • SUBSTITUTE SHEET (RULE 26)
  • the utility model ES 193496 U is known, consisting of a vertically stackable chair and molded from plastic material, characterized in that the lateral edge of the legs, in the lateral planes of the chair are vertical, the Backrest in its union with the seat and the rear legs is notched and the rear legs have an internally directed channel at least most of its length, which becomes the upper parts of the legs in said portion.
  • the main objective of this invention is to provide greater comfort with a seat width equivalent to the floor width of the chair.
  • the utility model ES 185271 U 1 is known, consisting of a chair obtained by pressing from a sheet of plastic material, which comprises legs with an "S" shaped cross-section in which the outer edge of Ia " S “of the front legs and the inner edge of the” S “of the rear legs is rounded in connection with the back of the chair.
  • the present invention solves in a fully satisfactory manner the problem described above. It consists of a chair, whose main characteristic and motive of the present application, is the height of the backrest, which is greater than those currently available in the market.

Abstract

La présente invention concerne une chaise empilable améliorée qui est formée d'une seule pièce en matière plastique moulée par injection. Le dossier (1) et l'assise (2) présentent dans leur partie arrière plusieurs nervures (5-5') qui sont reliées entre elles par des profilés perpendiculaires (6-6') traversant complètement d'un côté à l'autre le dossier (1) et l'assise (2), ainsi que des nervures arrières latérales (7-7') qui se trouvent dans la partie moyenne-basse des extrémités du dossier (1) et suivent la forme et la direction du dossier, et plusieurs nervures latérales (8-8') qui viennent croiser le dossier et qui font saillie de la région arrière de jonction entre le dossier (1) et les pattes arrières (3), ce qui permet d'obtenir une hauteur de dossier supérieure à celle des chaises que l'on peut trouver sur le marché et ce, sans perdre ses propriétés. Le rayon de la jonction (10) entre l'assise (2) et les pattes arrières (3) est supérieur à celui formé par l'assise (2) avec les pattes avant (4).
