Definitions

  • This invention concerns a back and/or sitting support for an operator at a fixed workplace in a room, such as a working chair in a hairdressing establishment.
  • body-support devices of various types, which, however, mainly aim to support the body in the sitting, lying or kneeling position. Supports for people in the standing position are less frequent, although the use of a 'platform' equipped with a backrest against which a person in the standing position can rest with the intention of reducing feelings of tiredness is known. In use, such platforms, however, reduce the freedom of movement at a workplace that requires temporary movements of the operator.
  • this invention In taking care of hair in a hairdressing establishment it is common to place the customer in a hairdresser's chair, after which the hairdresser, during the course of working, moves in the standing position around the customer approximately a half turn, i.e. one hundred and eighty degrees, and in doing this is often forced to adopt crouching working postures. This is very strenuous on the back, neck and legs. To facilitate execution of the work and reduce the strains mentioned above this invention concerns a back and/or sitting support that can be used by a hairdresser during the course of work.
  • the invention is characterized mainly by the back and/or sitti" i support being a unit attached to the floor that has a frame-like upper part, a 'support rail', which surrounds part of the working chair with a full opening forwards in the sitting direction and with space to work between the working chair and the support rail so that the support rail can form a support at the back for the operator's lumbar region and/or back while carrying out the work.
  • the invention is characterized by the back and/or sitting support possessing a column attached to the floor and centrally located on which the support rail can be raised and lowered in relation to the floor.
  • the invention is also characterized by the support rail being capable of being displaced in a horizontal guide which, in line with the support-rail's forward pointing opening, is firmly arranged at the upper part of the basic column.
  • the frame-shaped upper part, the 'support rail' is preferably on the top and/or inside clad with a cushion-like stuffing with a turning position on the frame that can be varied depending on the operator's body size and special requirements.

  • the box section tube (9) of the upper part (3) is designed with a line of horizontal holes (not shown) that permit adjustment of the upper part, the 'support rail' (3) in different horizontal positions in the working chair's sitting direction and locking of a set position using a transverse bolt (10).

  • the support construction consists of two inclined tubes (12) and a vertical tube (16) with respective tube ends attached to the support frame's tubular central part (11) and at the sleeve (9).
  • the upper part's frame construction can, alternatively in accordance with Figures 4 and 5, be designed with a rear support plate (17) to which the inner end of the transverse sleeve (9) is attached. Above this sleeve (9), at the support plate a Vee- like tubular stay (18) is attached and its ends attached to the tube (11).
  • a transverse stay (20) is firmly attached at the tube ends of the central part and at support blocks (19) which are attached at the rear tubular part (11).

  • the frame construction and/or cushion function can be designed so as to permit reconfiguration of the support body to temporary seats.
  • the support arrangement in accordance with the invention permits the upper part (3) to be lifted off after the bolt (10) has been removed and the upper part (3) displaced out of the horizontal guide (8).

Abstract

L'invention concerne un support de dos et/ou pour la position assise, prévu pour être utilisé sur un lieu de travail fixe dans une pièce, telle qu'une chaise de coiffeur. L'invention se caractérise en ce que le support de dos et/ou pour la position assise est une unité fixée au sol avec une partie supérieure de type cadre, et un 'rail de support' (3) qui entoure la chaise de travail en laissant un espace suffisant pour travailler entre la chaise et le rail de support (3), de sorte que ce dernier puisse constituer un support arrière pour la zone lombaire et/ou le dos d'une personne pendant qu'elle travaille.
