Embodiment Construction

[0022] According to FIG. 1, the seat panel 1, preferably made of wood, is fixedly connected via screw connections 4 to a support plate 7, which forms the upper bearing of a slide bearing via a dome-shaped inversion. lining. A thin foamed plastic sheet 2 glued to the seat panel 1 covers the carrier plate 7 and serves as a soft, non-slip seat surface. A gap 8 is provided in the middle of the seat plate, so that the dome of the support plate 7 rests on a hemispherical plastic part 5 pressed into the support pin, and the connected seat plate 1 can be tilted in all directions at least + / -20°. In order to keep the wear in this bearing low and nevertheless to achieve the required stability, steel is chosen as the material for the support pin 6 and has a diameter of 14 mm. The support pin 6 is fixedly connected to a height-adjustable post 14 by means of adhesive, clamping pin 15 or bolts. The strut 14 is vertically movable and fixed in a chassis formed by a plate 16 and at least th...

Abstract

The invention relates to a dynamic seat arrangement comprising a seat plate (1) supported by means of a bearing head (5) on the bottom of a support (14) with adjustable height stand or rest on a support surface. In order to ensure the user's automatic and natural movement while being free to move, the invention provides that the seat panel (1) has a gap (8) arranged in its center that expands from its top surface towards its bottom surface. ), a bearing bush (19) passes through the gap (8) in the seat plate (1) from below and is fixed, and the bearing bush (19) is placed on the bearing head (5) of a support pin (6), wherein the bearing The head (5) is spherical or hemispherical, thus creating a common point of rotation and pivot above the seat plate (1).

Description

technical field [0001] The invention relates to a dynamic seat arrangement comprising a seat plate which is supported tiltably and rotatably by means of a bearing head on a base frame with a height-adjustable column or on a support surface. Background technique [0002] A book by the author group SVSS is entitled "The Seat as a Burden (Sitzen als Belastung)" (Verlag pmsi Holdings Deutschland GmbH, Publisher, 1993, recommended by the German Seating Association (Bundesverband der deutschen Rückenschulene.V.)). The book's 200 pages explain that the correct seat is not a rigid fixture, but requires continuous mobility. Since these unrestricted movements cannot be achieved while sitting in an ordinary chair, it is suggested in the book that one must consciously alternate between various sitting positions. It describes how difficult it is to sit and exercise physically during the workday and at work. But some recommended sitting positions do not allow for desk work or other act...
