Element and device for seating furniture

Abstract

An element of a device, in particular an element of a seating furniture assembly or of a seating furniture assembly component is provided. In addition, a device for an item of seating furniture, in particular a seating furniture assembly, for example a pivot mechanism, has an element of this type. Furthermore an item of seating furniture having a device of this type or having an element of this type is possible. In order to simplify the construction of items of seating furniture, the use of a deformation element which is integral, that is to say integrated into the device, which is deformable, which is composed preferably of a plastics material, and which serves as an energy storage member, is proposed.

         14 . An element of a device, the device being selected from the group consisting of a seating furniture assembly and a seating furniture assembly component, the element being an elastically deformable element being integrated in single-piece form into the device and serving as an energy storage member. 
     
     
         15 . The element according to  claim 14 , wherein said elastically deformable element is deformable owing to an exertion of load on the device, which said exertion of load has an aim of causing a movement of the device. 
     
     
         16 . The element according to  claim 14 , wherein said elastically deformable element is composed of a plastic material. 
     
     
         17 . The element according to  claim 14 , wherein said elastically deformable element is configured so as to deform differently in a manner dependent on a direction of action of a force acting thereon, by virtue of said elastically deformable element having a plurality of members or structure planes which act in parallel and which have stiffnesses dependent on the direction of the action of the force. 
     
     
         18 . (canceled) 
     
     
         19 . A device for an item of seating furniture, the device comprising:
 at least one elastically deformable element being integrated in single-piece form into the device and serving as an energy storage member.   
     
     
         20 . The device according to  claim 19 , wherein the device is a pivot mechanism, in which a pivoting of a backrest support rearward induces a following movement of a seat support. 
     
     
         21 . The device according to  claim 20 , wherein:
 said pivot mechanism has a multi-jointed coupling gear; and   said at least one elastically deformable element is formed as an integral constituent part of said multi-jointed coupling gear.   
     
     
         22 . The device according to  claim 21 , wherein said at least one elastically deformable element has a plurality of virtual centers of rotation in order to provide an infinite joint gear for said pivot mechanism. 
     
     
         23 . The device according to  claim 20 , wherein a pivoting movement is provided by said pivot mechanism and would not be implementable without a deformability of said at least one elastically deformable element. 
     
     
         24 . The device according to  claim 23 , wherein the pivoting movement is a movement in a case of which the backrest support pivots through a pivot angle of greater than 5°. 
     
     
         25 . The device according to  claim 20 , wherein:
 said at least one elastically deformable element is one of a plurality of elastically deformable elements; and   the device having a single-piece seat support-base support combination, in which a seat support can be moved relative to a base support by being connected in single-piece form to the base support via a number of said elastically deformable elements.   
     
     
         26 . The device according to  claim 19 , wherein said at least one elastically deformable element is an only energy-storing structural part of the device. 
     
     
         27 . The device according to  claim 19 , wherein the item of seating furniture is a seating furniture assembly. 
     
     
         28 . The device according to  claim 21 , wherein said at least one elastically deformable element is a coupler or a part of said coupler. 
     
     
         29 . An item of seating furniture, comprising:
 at least one element of a device and having an elastically deformable element being integrated in single-piece form into the device and serving as an energy storage member; or   an apparatus for an item of seating furniture, said apparatus containing said at least one elastically deformable element being integrated in single-piece form into said apparatus and serving as an energy storage member.   
     
     
         30 . The item of seating furniture according to  claim 29 , wherein the item of seating furniture is an office chair.
