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 25):
The backrest according to  claim 16 , wherein some or all of the struts ( 4 ,  9 ,  13 ,  17 ) are articulated to the insides of the strips on one side or on both sides in an articulated manner, i.e. in a hinged manner, and the hinge axis of the articulated articulations on the inside of the strips ( 2 ,  3 ;  7 ,  8 ;  11 ,  12 ;  15 ,  16 ) are arranged so as to be capable of being displaced in the longitudinal direction thereof and can be locked in each displacement position.
