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 17):
The backrest according to  claim 16 , wherein the connecting webs ( 4 ) between the front and the rear column strap ( 3 ) are stiff flat struts ( 4 ), which are articulated on the column straps in an oblique-angled manner between the front column strap ( 2 ) and the rear column strap ( 3 ) in an articulated manner on both ends across the width thereof, so that a displacement of the front column strap ( 4 ) against the rear column strap ( 3 ) effects a relative displacement thereof against one another in strap direction as well as deformation, and that the webs ( 9 ) between the transverse straps ( 7 ,  8 ) form elastically flexible webs, which are curved once or several times, wherein these webs are fastened in an articulated manner on both ends on the inside of the opposite insides of the transverse straps ( 2 ,  3 ).
