Definitions

  • the invention relates to a chair with a height-adjustable lumbar part having a padded backrest, in which the lumbar part is arranged between an upholstery and a plate-shaped cushion support and is supported on the front thereof and through at least two mutually separate parallel vertical guide grooves with one from the rear of the Backrest accessible handle is connected.
  • Such a chair is specified in DE 42 27 246 A1.
  • This known lumbar support is arranged between an upholstery and a support plate and is connected by means of a spring plate which is guided downwards to an adjustment handle which projects through a slot in a support bracket on the back of the support plate.
  • the bracket has a double U-shaped cross section with two inner and outer side legs. There is a guide groove in each of the inner side legs, in which the lumbar support is pivotably mounted via a horizontal pivot pin.
  • a locking structure is provided with which a locking portion of the handle cooperates to fix the lordosis part to a desired height.
  • the section of the spring plate is relatively long, so that difficulties can arise when guiding the lumbar support.
  • the adjustment mechanism is also relatively complex.
  • the invention has for its object to provide a chair of the type mentioned, which has a simple structure of the lumbar adjustment part and thereby ensures good manageability.
  • the guide grooves are formed in the cushion support and are separated from one another by a guide web, and that a locking structure is provided on the front, the rear and / or on the sides of the guide web facing the guide grooves, with which a locking section of the lordosis part and / or the handle cooperates to fix the lordosis part at a desired height.
  • the parallel guide grooves provide clear guidance, with the guide web offering easy attachment and locking options.
  • the production of the guide elements and locking structure is simple, for example in a molding process.
  • the handle does not interfere with the outside, if it is provided that the handle is plate-shaped and is aligned essentially parallel to the cushion support and is displaceable. It also contributes to good leadership.
  • the handle has a gripping section projecting towards the rear.
  • a stable structure which results in a favorable accommodation of the lumbar support with the adjustment mechanism, is that a rear plate-like carrier is attached to the back of the cushion carrier, and that the handle is arranged between the cushion carrier and the carrier and is accessible via a recess in the carrier ,
  • Fig. 3 shows a back carrier of the backrest
  • Fig. 4 is a cushion support of the backrest.
  • Fig. 1 shows a schematic exploded view of a backrest 1 of a chair.
  • the backrest essentially consists of a padding 4, a plate-shaped cushion carrier 3 and a rear carrier 2 arranged on the rear, which e.g. can be screwed or riveted to the cushion support 3.
  • the cushion carrier 3 and the rear carrier 2 are formed, for example, from plastic and suitably adapted to the contour of the back, as is known per se.
  • a lumbar part 5 is arranged such that it can be adjusted in height, as can also be seen in FIG. 2.
  • the lordosis part 5 is convexly curved towards the front and, for example, also made of plastic.
  • the lordosis part 5 is molded into the cushion carrier 3 during the manufacturing process and into a lordosis field 3.1 is held in the cushion carrier 3 by means of injection webs 3.1 1 and can easily be broken out of this for further processing, as can be seen in FIG. 4.
  • the lordosis part 5 is opposite and a plate-shaped handle 5.1 is arranged so that it can slide downward.
  • the handle 5.1 is connected to the lordosis part 5, for example by means of screws or similar fastening elements, through two vertical parallel guide grooves in the form of slot-like openings in the cushion support 3, a guide web 3.2 being present between the guide grooves 3.3, which provides a holder and clear guidance for the lordosis part 5 with the handle 5.1 attached to it.
  • a locking element 5.2 which is directed inwards towards the cushion carrier 3 and which interacts with a rib-shaped or similar locking structure 3.22 formed in the guide web 3.2.
  • the resilient, preferably molded locking element 5.2 contributes to the stable guidance of the lordosis part 5 by the support on the guide web 3.2.
  • elements 5.3 projecting into the guide grooves 3.3 can be provided with vertical sliding edges adapted to the edges of the guide grooves 3.3.
  • the rear support 2 is provided in its lower region with a portal-shaped or similar cutout 2.1, which in the present case is open at the bottom, via which the plate-shaped handle 5.1 can be operated from the rear of the backrest 1.
  • the handle 5.1 has a gripping section 5.1 provided with corrugations 5.1 2 or the like in order to simplify the displacement of the handle 5.1 with the lordosis part 5.
  • the handle 5.1 does not apply to the outside, but on the other hand its function is easily recognizable.

Abstract

L'invention concerne un siège à dossier rembourré (1) présentant une pièce lordosique réglable en hauteur (5), dans lequel la pièce lordosique (5) est disposée entre un rembourrage (4) et un porte-rembourrage (3) en forme générale de plaque et prend appui sur sa partie avant, et est raccordée, par au moins une rainure de guidage verticale (3.3) formée dans le porte-rembourrage (3), avec un moyen de manipulation (5.1) accessible par l'arrière du dossier (1). L'invention vise à obtenir une manipulation simple en même temps qu'une structure simplifiée du siège précité et, en conséquence, est caractérisée en ce qu'il est prévu dans le porte-rembourrage (3), au moins deux rainures de guidage (3.3) parallèles, séparées l'une de l'autre par une nervure de guidage (3.2), et en ce qu'il est prévu sur la partie avant, la partie arrière et/ou sur les côtés de la nervure de guidage (3.2) faisant face aux rainures de guidage (3.3), une structure d'arrêt (3.22) avec laquelle coopère une section d'arrêt (5.2) de la pièce lordosique (5) et/ou du moyen de manipulation (5.1), en vue de fixer ladite pièce lordosique (5) à une hauteur voulue.
