Definitions

  • the invention relates to a piece of seating furniture, preferably upholstered furniture, with a seat part and a backrest which is height-adjustable in relation to this seat part along guides.
  • the backrest is deliberately designed to be deliberately low for aesthetic reasons at the request of the buyer and the planning interior designer; however, this leads to the fact that the use of such seating becomes permanently uncomfortable because the upper part of the back with the shoulder area and the head of the user cannot be supported on the backrest.
  • the object of the present invention is to design a piece of seating furniture of the type mentioned at the outset in such a way that the height adjustment of the backrest is simple and effortless is feasible, regardless of the location and the grouping of this seating with a conveniently accessible and operable mechanism.
  • a drive is provided for the stepless adjustment of the backrest along its guides.
  • This measure ensures that the backrest can be moved from a low position (normal position) corresponding to the aesthetic needs and the demand for low furniture to a high position (use position) corresponding to the demand for convenience by simple manipulation - Thanks to the stepless drive - at a selectable altitude according to the individual needs and body size of the user. If the backrest with its front upholstery is guided against the rear edge of the upholstery of the seat part, the upholstered seating furniture also has a pleasing appearance with the backrest upright.
  • the stepless drive can basically be of any type within the scope of the invention and it can be designed and equipped in an extremely varied manner according to the prior art, for example as a mechanical, electromechanical, electrical or hydraulic drive with control. Organize any type, if necessary also automatically with a control that can be triggered by the use (load on the seat) ...
  • the drive consists of a crank or the like, a drive shaft with pinion and a rack.
  • the crank or the end of the drive shaft assigned to it can then be arranged in the front area of the seat part in a cavity located below the seat surface.
  • the seat furniture shown only, for example, without armrests essentially consists of the seat part 1 and the backrest 2. In these two parts, the upholstery 1 'or 2' is only indicated by dashed lines.
  • a rack and pinion drive which comprises a crank 9, a drive shaft 10, a pinion 11 and a rack 12 fastened to an upright 12 'of the seat part 1.
  • the crank 9 located on one end face of the seat part 1 is connected to the pinion 11 mounted below the backrest 2 via a drive shaft 10 which penetrates the seat part 1 centrally. If desired, the crank 9 can also be stored separately and attached to the free end of the drive shaft 10 only if necessary.
  • the drive shaft 10 is supported in the cross struts 13 and 14 of the seat part 1 and in the bearing 15 of the rear wall 6 of the seat part 1.
  • a detachable or movable cover couldsver patued cover.
  • the side parts 19 of the backrest 2 engage with downward extending cheeks 20 with play between the side walls 21 of the seat part 1.
  • the backrest 2 forms a stop 22 which extends inwards into the seat part 1 and which, together with part of the seat surface of the seat part, limits the height adjustment of the backrest 2 towards the top.
  • the side walls 21 of the seat part 1 are spatially stiffened by cross struts 23, the side parts 19 of the backrest 2 by cross struts 24.
  • the furniture according to the invention can be designed with or without armrests within the scope of the invention and can consist of a single element or of several arranged next to each other and with each other, e.g. elements connected to form a bench.
