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 16):
A backrest for a chair or seat to stimulate subtle movements in the back muscles, wherein the backrest comprises a central phoronomic element ( 1 ) of two column straps ( 2 ,  3 ), which are intended to extend upwards from the center of the rear end of the sitting surface ( 5 ), and which can be fastened to the chair or seat for this purpose, and of a number of phoronomic elements ( 6 ), which protrude laterally like ribs on both sides from the central phoronomic element ( 1 ), in each case of two transverse straps ( 7 ,  8 ) to support the back muscles of the sitting person by means of the front transverse straps ( 7 ) on both sides of the person's spine,\n wherein the backrest comprises a central phoronomic element ( 1 ), which extends upwards from the center of the rear end of the sitting surface ( 5 ), wherein it is embodied so as to be capable of being tilted backwards with adjustable resistance, and wherein its front column strap ( 2 ) can be bent so as to follow the course of a spine, the connecting webs ( 4 ) are embodied so as to be longitudinally changeable to the rear column strap ( 3 ), or to be adjustable in an articulated manner or that their articulation on the opposite insides of the column straps ( 2 ,  3 ) on the column straps ( 2 ,  3 ) are embodied in a longitudinally displaceable manner, so that they define the distance of the column straps ( 2 ,  3 ) in relaxed position and said front column strap ( 2 ) changes in shape and length in accordance with the arrangement and embodiment of the connecting webs ( 4 ) in response to local pressure thereon, and wherein, starting at the front column strap ( 2 ) on both sides, a plurality of transverse strips ( 7 ), are integrally molded like ribs ( 6 ) on both sides of the spine of the sitting person to support the back sections, are in each case connected via webs ( 9 ) to rear transverse strips ( 8 ), which, in turn, are integrally molded on the front ( 2 ) or rear column strap ( 3 ), and wherein these connecting webs ( 9 ) are also embodied so as to be longitudinally changeable or adjustable in an articulated manner or that their articulations to the transverse strips ( 7 ,  8 ) thereon are embodied in a longitudinally displaceable manner, so that these webs ( 9 ) define the distance of the transverse strips ( 7 ,  8 ) in relaxed position and the front transverse straps ( 7 ) change in shape and length in accordance with the arrangement and embodiment of the connecting webs ( 9 ) in response to local pressure thereon.
