Seating Furniture, In Particular Office Chairs

Abstract

In order to provide an office chair having a comparatively low constructive effort and expense, a degree of comfort comparable with that of a synchronization mechanism, the chair has a seating element with a seating surface and a back element pivotable around a lateral axis and linked in a jointed manner to the seating element. The seating surface of the seating element is configured in a way that a user performs a movement, which follows the movement of the back element, when the back element is pivoting to a rear position. As a result, a synchronous movement of the body of the user with the movement of the back element is facilitated, without the whole seating element performing the synchronous movement.

1 . A chair, comprising: 
 a fixed seating element having a seating surface; and    a back element being pivotable around a lateral axis and linked in a jointed manner to said fixed seating element, said seating surface of said seating element being configured such that a user, when pivoting said back element towards a rear position, executes a movement that follows a movement of said back element.    
     
     
         2 . The chair according to  claim 1 , wherein said seating surface has at least two seating areas disposed behind one another in a longitudinal direction of the chair, said seating areas differing with regard to a type of upholstery used.  
     
     
         3 . The chair according to  claim 2 , wherein said seating areas include at least one rear seating area with an upholstery that allows the user to roll down backwards.  
     
     
         4 . The chair according to  claim 1 , wherein: 
 said fixed seating element has an attachment for receiving a chair post; and    said lateral axis is disposed in front of said attachment for the chair post, as seen in a longitudinal direction of the chair.    
     
     
         5 . The chair according to  claim 1 , further comprising spring elements disposed in a generally horizontal position in said seat element for pre-stressing said back element.  
     
     
         6 . The chair according to  claim 1 , wherein the chair is an office chair.
