Definitions

  • the invention relates to a chair with a seat part and a backrest part, which are supported on a pedestal.
  • a relatively complex chair mechanism is used especially in office chairs, which offers a separate or coordinated mobility of the backrest and the seat plate.
  • the manufacturing cost of such office chairs are relatively high, and the complexity of the chair mechanism is also given a certain susceptibility to interference.
  • a chair in particular row chair, is known in which is improved by simple, inexpensive means of existing in chairs without chair mechanism seat comfort.
  • a chair is provided with a frame consisting of two arranged on both sides of the chair, a substantially U-shaped frame made of rod material, the front and rear legs and lower, connecting the legs runners, and which a supported on the frame seat plate and supported on the frame backrest comprises.
  • the seat plate made of a flexible material, which is pulled down at the front edge arcuately to the front legs and firmly connected to the front legs.
  • the backrest is firmly connected to the rear edge of the seat plate.
  • the rear legs in the upper portion are angled forwardly and / or inclined generally forwardly, and further an intermediate piece is provided, which at the front end on a transverse axis pivotally connected to the upper end of the rear legs and further back with the underside of the seat plate and the backrest is connected.
  • Such a chair has only a single axis, namely the transverse axis at the upper end of the rear legs, which connects to the intermediate piece.
  • the invention aims to provide a chair with an extremely simple construction associated with a cost-effective production, which essentially manages without axes of movement, provides a comfortable seating comfort and allows a versatile applicability.
  • a chair is provided with a seat part and a backrest part, both of which are supported on a pedestal.
  • This chair is characterized in that the seat part has a Eigenfederungs- assets and at the front, facing away from the backrest end end is bent at a distance to form a gap on itself arcuately, the backrest part curved approximately L-shaped and optionally with the inclusion of a reverse bend , is formed with Eigenfederungs- assets and extends to the bent end of the seat part, and that the mutually facing ends of the seat part and the backrest part are fixedly clamped by means of a transversely directed, rigid connection part, wherein a body-synchronous movement of the seat part and backrest part takes place.
  • the interpretation is characterized in that the seat part has a Eigenfederungs- assets and at the front, facing away from the backrest end in the direction of the pedestal down bent, the backrest part curved approximately L-shaped, optionally with the inclusion of a Gegenbie- tion, is formed with an own resilience, extends to the bent end of the seat part and is congruent bent to the bent end of the seat part, and that the superimposed ends of the seat part and the backrest part are fixed by means of a transverse, rigid connection part, clamped, wherein a Body-synchronous movement of the seat part and backrest part takes place.
  • the respective self-suspension capability or the inherent flexibility or the inherent flexibility is thus utilized both in the seat part and in the back part in order to provide a sitting comfort similar to a chair with a body-synchronous chair mechanism.
  • the chair according to the invention also determines the bent portion of the seat part, the resilient portion of the seat part, when a person takes place on this seat part.
  • the suspension behavior of the backrest part is determined by the region of the backrest part which faces the transversely directed, rigid connecting part. This transversely directed, rigid connecting part defines both the end of the seat part and the backrest part and holds these ends firmly taut, so that the corresponding adjacent areas of seat part and backrest part determine and form the resilient region of the seat part and the foot part.
  • the transverse connecting part is arranged with respect to the longitudinal extension of the seat part in the region of the front third. hereby The desired self-suspension capacity of the seat part and backrest part can be adjusted and selected most favorably.
  • the chair according to the invention is designed such that one chooses a corresponding material with own resilience for the seat part and / or the backrest part.
  • the desired self-suspension capability can be imparted to the seat part and / or the backrest part by additional material processing, such as by inserting slots or the like.
  • the composite unit formed by the seat part, backrest part and these two fixing rigid connecting part is designed such that it can be preferably connected by means of the rigid connecting part fixed to the pedestal. If this transversely directed, rigid connecting part is arranged for clamping the two opposite ends of the backrest part and seat part in the front third of the longitudinal extent of the seat part, sufficient chair stability is ensured in the case of use, since this composite unit, regardless of the type of pedestal of the entire chair assembly always gives favorable balance of gravity.
  • Essential in the chair design according to the invention is the fact that it provides a construction of seat, backrest and pedestal, in which one manages without swivel axes and without complex body-synchronous chair mechanism, and the chair still gives a seating comfort similar to a chair with chair mechanics.
  • both the seat part and the backrest part is a Assigned predetermined spring range, since the two mutually facing ends of the seat part and backrest part are held fixed by means of a transversely directed, rigid connection part clamped. Each adjacent to this fixed clamping areas of seat and backrest part determines the respective resilience of the seat part and backrest part.

Abstract

L'invention concerne une chaise avec une partie d'assise et une partie de dossier qui reposent toutes deux sur un bâti de pied. La partie d'assise possède une capacité propre d'amortissement et est recourbée sur elle-même en forme d'arc à son extrémité antérieure, opposée à la partie de dossier, en ménageant un espace intermédiaire. La partie de dossier prend une forme sensiblement en L et peut éventuellement comprendre une contre-courbure. La partie de dossier possède également une capacité propre d'amortissement et atteint l'extrémité recourbée de la partie d'assise. À l'aide d'une pièce de liaison rigide orientée transversalement, les extrémités de la partie d'assise et de la partie de dossier qui sont tournées l'une vers l'autre sont solidarisées et immobilisées. Dans une autre forme de réalisation de la chaise, la partie d'assise possède une capacité propre d'amortissement et, à son extrémité antérieure opposée à la partie de dossier, elle est recourbée vers le bas en direction du bâti de pied. La partie de dossier conçue de manière correspondante, avec une capacité propre d'amortissement, atteint l'extrémité recourbée de la partie d'assise et est également recourbée en direction du bâti de pied, de manière congruente avec l'extrémité de la partie d'assise. Les extrémités de la partie d'assise et de la partie de dossier reposant l'une sur l'autre sont immobilisées et solidarisées par une pièce de liaison rigide orientée transversalement, si bien que l'on obtient un mouvement de la partie d'assise et de la partie de dossier qui est synchronisé avec le corps. Les régions élastiques de la partie d'assise et de la partie de dossier sont formées et déterminées à partir de ces pièces de liaison rigides. La configuration est sélectionnée de manière à obtenir un mouvement de la partie d'assise et de la partie de dossier qui est synchronisé avec le corps. Dans la direction longitudinale de la partie d'assise, la pièce de liaison disposée transversalement est de préférence implantée dans le tiers antérieur. De cette manière, la pièce de liaison peut être solidarisée avec le bâti de pied qui lui est associé, qui peut être un bâti à roulettes, un bâti fixe ou similaire.
