Definitions

  • the backrest can be connected to the backrest support so that it is adjustable in height.
  • the backrest or the seat support can be equipped with a longitudinally adjustable element.
  • the backrest part is tiltably mounted on the backrest support so that it can be moved from a quasi upright position to an inclined position when the backrest folds from the sitting position into the supporting position.
  • an inclination of the backrest part between 0 ° and 60 °, preferably between 5 ° and 45 ° relative to a horizontal, has proven to be particularly suitable for a standing, leaning or supported position.
  • FIGS. 1a and 1b A first embodiment of the present invention is illustrated in FIGS. 1a and 1b.
  • This initially comprises generally (i.e. like the other embodiments as well) a chair 1 with a seat 4, a backrest support 2 and a backrest 3, the backrest support 2 being mounted on the seat 4 and the backrest 3 on the backrest support 2.
  • the chair 1 is designed so that in a sitting position (cf. FIG. 1 a) a user can sit on the seat 4 and lean his back against the backrest 3.
  • the chair 1 comprises a backrest part 5 different from the backrest 3, the backrest 3 being tiltably connected to the backrest support 2 so that it can be folded from the seated position into a support position in the direction of the seat 4 or a central axis X.
  • the backrest part 5 is coupled to the backrest 3 in such a way that the backrest 3 aligns the backrest part 5 when folding from the sitting position (see. Fig. 1a) into the support position (see Counter-backing part
  • the seat 4 is mounted on a seat post 9 through which the central axis X extends.
  • the underframe or the base 7 is arranged, which has castors 8.
  • the castors 8 are preferably designed to be braked, i.e. in any case they partially block against the chair 1 from rolling away to the side if, for example, the user is leaning against the backrest part 5 in the support position.
  • the perch 9 is mounted in a hydraulic cylinder 10, via which it can be adjusted vertically up and down. A seat height of the chair 1 can thus be adjusted.
  • the seat post 9 is rotatably held in the hydraulic cylinder 10 so that the seat 4 can be rotated about the central axis X.
  • the upper end of the backrest part 5 is movably coupled to the backrest 3 via the second, upper axis A 2.
  • the lower end of the backrest part 5 is fixedly connected to the backrest part carrier 6 and can thus be bent about the third, central axis A 3 when the backrest 3 is tilted.
  • the backrest 3 is in turn tiltably connected to the backrest support 2 by being mounted on the backrest support 2 so as to be rotatable about the first, lower axis Ai.
  • FIG. 3b Another preferred embodiment of the present invention is indicated in FIG. 3b. This comprises a guide 12 (shown in dashed lines) which is arranged at the upper end of the backrest part carrier 6 and in which the backrest part 5 is received in a sandwich-like manner.
  • the upper end of the backrest part 5 is coupled to the backrest 3 via the movable, second axis A 2.
  • the movable, second axis A 2 can be arranged in the backrest 3 or behind the backrest 3. It can furthermore be arranged displaceably in and / or relative to the backrest 3. Overall, a particularly stable and safe sitting position can be achieved by means of this embodiment, since the center of gravity of the respective user is shifted further in the direction of the central axis X.

Abstract

La présente invention concerne une chaise (1) comportant une assise (4), un support de dossier (2) et un dossier (3), le support de dossier (2) étant monté sur le siège (4) et le dossier (3) étant monté sur le support de dossier (2), et la chaise (1) étant conçue de sorte que, lorsque la chaise est dans une position d'assise, un utilisateur peut s'asseoir sur le siège et reposer son dos contre le dossier (3). La chaise (1) comporte en outre une partie d'appui (5), qui diffère du dossier (3), le dossier (3) est relié de manière inclinable au support de dossier (2), et il peut donc être basculé dans la direction du siège (4), depuis la position d'assise dans une position de support, et la partie d'appui (5) est couplée au dossier (3) de sorte que, lorsque celui-ci est basculé de la position d'assise dans la position de support, le dossier (3) oriente la partie d'appui (5) de sorte que l'utilisateur peut appuyer ses fesses sur la partie d'appui (5).
