Abstract:
The invention relates to a seat ( 1 ), in particular an office chair, comprising a seat support ( 3 ) for a seating surface ( 6 ) and comprising a backrest support ( 4 ) of a backrest ( 5 ), which is held on the seat support ( 3 ) so as to be able to move in a tillable manner to the side, wherein the backrest support ( 4 ) comprises two support aims ( 4 a,  4 b ) which are configured to be flexible and/or articulated laterally and spaced apart from one another. Preferably, the seating surface ( 6 ) and/or the backrest ( 5 ) comprises a curved seat shell and/or backrest shell ( 6 a,  5 a ) provided with a cover ( 6 b,  5 b ) with a number of flexible curved ribs ( 15, 16 ) on the edge of the shell, wherein the cover is stretched by the seat shell and/or backrest shell ( 6 a,  5 a ) such that when the cover ( 6 b,  5 b ) is loaded, the bending of the curved ribs ( 15, 16 ) is altered.

Claim (Index 13):
A seat, in particular an office chair, comprising:\n a seat support for a seating surface; a backrest support coupled with the seat support so as to be able to move relative to the seat support, the backrest support comprising;\n a backrest cover having a periphery including first and second lateral edges; and \n a curved shell made of a flexible material, the shell defining first and second lateral peripheral edges and a third peripheral edge interconnecting the first and second peripheral edges, the shell including a plurality of ribs extending in opposing directions, each of said ribs spaced apart from adjacent ribs such that each rib is capable of flexing independently of the other ribs, each of the ribs extending outwardly to a free end at one of the first and second peripheral edges of the shell; \n wherein the backrest cover is connected to each of the first and second peripheral edges of the shell, at least a central portion of the backrest cover spaced from the shell on a lateral cross section of the backrest cover and the shell, wherein the first lateral edge of the cover is supported on the first lateral peripheral edge of the backrest shell and associated with the first set of ribs and the second lateral edge of the cover is supported on the second peripheral edge of the backrest shell and is associated with the second set of ribs, and wherein at least one of the ribs becomes more curved toward the seating surface when the cover is loaded in a direction toward the flexible curved shell.
