Abstract:
The backrest brings about the stimulation of underlying movements in the back muscles. The backrest consists of at least one moveable element ( 1 ) formed of two flexible column strips ( 2, 3 ) running over one another and connected via struts ( 4 ), and which track the spinal column of the person using the chair with a gap. This element ( 1 ) extends upwards from the centre of the rear end of the seating surface. The front column strip carries a number of moveable elements ( 6 ) laterally protruding on both sides like ribs ( 6 ) from the central moveable element ( 1 ), each having two transverse strips ( 7, 8 ) for supporting the back region of the seated person exclusively on both sides of their spinal column. Each time the backrest constructed in this way is leant upon, a movement of its contact surface is brought about in different directions, and thereby a massaging of the back muscles of the user.

Claim (Index 29):
The backrest according to  claim 16 , embodied as sitting surface, wherein the column straps run in the middle along the sitting surface and the transverse straps run concavely, seen from above, for accommodating the thighs of a person sitting thereon, and wherein the sitting surface, which is formed by the upper transverse straps, and the backrest, which is formed by the front transverse straps of the backrest, are in each case covered with a cover cushion, which is divided into a plurality of compartments, which are each filled with a gel.
