Definitions

  • the invention relates to seating furniture with a seating surface provided by a seating surface element and at least one backrest, which is connected to the seating surface element via a supporting structure and can be arranged at different locations on the seating surface, and a furniture fitting, in particular for the seating furniture, comprising a connecting element and at least one two rails connected to the connecting element according to the preambles of the independent patent claims.
  • Seating furniture with backrests that can be placed in different places on the seat surface are used wherever there is a need to provide seating with stationary seat surfaces, which offer the user the choice between different seating positions and orientations.
  • Known sofas with loose cushions which can be placed on or on the seat as desired and thus allow an individual design of the arm or backrest area and orientation when sitting.
  • Sofas are also known in which backrests can be arranged at different locations on the seat surface by means of complex movement mechanisms.
  • the first-mentioned sofas have the disadvantage that the cushions have an undefined position in many positions, which results in an untidy overall picture, and is often only due to a lack of connection with the actual supporting structure of the sofa Suitable backrest, the second-mentioned sofas are quite expensive to manufacture and due to their complicated mechanisms in use prone to failure and sensitive.
  • Seating furniture is a seating element which provides a seating surface for one or more users, and one or more backrests which can be placed at different locations on the seating surface and are connected to the seating element via a supporting structure in such a way that the respective backrest is carried by the supporting structure is and when a user is leaning against a drifting apart of the seat and backrest is prevented.
  • the support structure comprises a rail element extending essentially in the horizontal direction, i.e. a rail element which extends in a horizontal plane or a rail element which extends at different locations along its longitudinal extent at different heights and has an overall horizontal extent which is a multiple of its total vertical extent.
  • the rail element is preferably rigidly connected to the seat surface element or at least firmly connected to it in the direction of its longitudinal extension, in the latter case in a direction transverse to it
  • Longitudinal extent can be movable relative to the seat surface element, for example vertically and or horizontally displaceable transversely to its longitudinal axis.
  • the backrest is carried by the rail element and is guided by the rail element along part of the longitudinal extent or along the entire longitudinal extent of the rail element. slidable, whereby the backrest can be arranged at different locations on the seat.
  • the support structure preferably comprises one or more connecting elements arranged on and supported by the rail element, which carry the backrest or backrests and are guided by the rail element and can be displaced along at least part of its longitudinal extent.
  • the backrest can also be designed such that it itself provides corresponding connecting elements.
  • the connecting elements are positively connected to the rail element in such a way that torque can be transmitted from the respective connecting element to the rail element around the longitudinal axis of the rail element, in the case of a curved rail element around its longitudinal axis in the region of the connection between the connecting element and the rail element.
  • Such a torque can arise, for example, from the weight of the backrest attached to the connecting element and / or from a user leaning against the backrest carried by the connecting element.
  • Seating furniture of this type allows the backrests to be arranged in different places on the seat surface by simply moving the same and at the same time has an extremely simple and robust construction, which also allows a clear visual division of the individual elements of the seating furniture.

  • the rail element and the connecting element are connected to one another in such a way that it is not possible to separate the rail element and connecting element during normal use.
  • This can advantageously be achieved in that they are positively connected in all directions transverse to the longitudinal extension of the rail element, in the case of curved rail elements transverse to its longitudinal axis in the region of the connection between the connecting element and the rail element, and at the ends of the Rails mechanical stops are arranged which limit the displacement of the connecting element beyond the end of the rail element.
  • the connecting element and possibly also a backrest that is inseparably connected to the connecting element is captively attached to the seating furniture.
  • the rail element is arranged above the seat surface or above a plane formed by it, preferably at a height at which the average lumbar spine is located when used by an average user.

  • the backrest has exactly one mounting rail and this is also connected to the connecting element in such a way that the transmission of a torque about the longitudinal axis of the mounting rail in the region of the connection from the mounting rail to the connecting element is possible, this results in a very uncomplicated construction, which is a Offers maximum freedom of design. If the or the support rails are connected to the connecting element in such a way that they cannot be separated when used as intended, the backrest is captively attached to the connecting element and, when the connecting element is captively attached to the rail element, also captively attached to the seating furniture.

Abstract

L'invention concerne un canapé comprenant une surface d'assise (2) et un dossier (3) qui peut être placé, par déplacement horizontal, à différents endroits sur la surface d'assise (2). Le dossier (3) est relié de manière imperdable par l'intermédiaire d'une structure support à l'élément de surface d'assise (1) fournissant la surface d'assise (2) et est supporté par un chariot coulissant (5) qui est lui-même supporté par un rail horizontal (4) de la structure support, placé au-dessus de la surface d'assise (2), et qui peut être déplacé le long de ce rail en étant guidé par ce dernier. La liaison entre le chariot coulissant (5) et le rail est réalisée de sorte qu'un moment de rotation généré par des forces d'appui appliquées au dossier (3) autour de l'axe longitudinal du rail (4) peut être transmis du chariot coulissant (5) au rail (4). Un canapé de ce style permet un positionnement sûr du dossier (3) à différents endroits sur la surface d'assise (2) et est en outre de réalisation simple et robuste.
