Definitions
- the present invention relates to a dynamic seating device with a seat plate, which is tiltably and rotatably mounted by means of a bearing head on an under-frame with a height-adjustable column or on a bearing surface.
- a stool which through cylindrical segments placed one above the other allow movement of the seat face over two horizontal axes offset by 90°, is known as a seating device, which should improve sitting from a health point of view, from German Patent DE 201 10 832 U1.
- a seating device which should improve sitting from a health point of view, from German Patent DE 201 10 832 U1.
- both fulcrums of the coccyx are spaced too far apart to allow physiological optimum and homogeneous transmission of movement to take place.
- German Patent DE 295 16 794 U1 whose main feature however is a flexible seat with a resetting force and therefore does not meet the demands made here.
- the object of the present invention is to create a seating device of the kind initially specified, which automatically allows natural movements of the user at the same time with free mobility.
- the seat plate comprises a recess arranged in its centre, becoming larger from its top side towards its lower side, that a base plate with a dome-shaped protuberance is secured in the centre of the seat plate on its top side, that the base plate rests on the bearing head of a support pin, wherein the bearing head is shaped hemispherically and that the support pin is rigidly connected to the column or to a plate forming the bearing surface and protrudes through the recess through the seat plate, so that the seat plate can tilt in all directions and rotate without hindrance.
- a conical bush which is secured to the lower side of the seat plate, protrudes through a central hole in the seat plate, that the bush rests on the bearing head of a support pin, wherein the bearing head is shaped spherically, and that the support pin is rigidly connected to the column or to a plate forming the bearing surface, so that the seat plate can tilt in all directions and rotate without hindrance.
- the object stated is achieved in accordance with a third teaching of the present invention by the fact that the seat plate comprises a recess arranged in its centre, becoming larger from its top side towards its lower side, that a conical metal cap, reduced in diameter from bottom to top, is passed from below through the recess in the seat plate and secured, and that the metal cap rests on the bearing head of a support pin and forms the bush, wherein the bearing head is shaped hemispherically so that a common rotating and swivelling point arises above the seat plate.
- the present invention therefore consists of a dynamic seating device, in which to achieve natural movements of the user at the same time with free mobility, according to the invention it is proposed that the seat plate has a central recess running conically from top to bottom with a bush inserted from below, which rests on the spherical or hemispherical bearing head of a support pin, so that a common rotating and swivelling point arises above the seat plate, not under it.
- This invention concerns a seating device, which prevents posture injuries particularly within the extended spinal column region, by permitting free mobility and simultaneously physiologically centred sitting through a common rotating and swivelling point above the seat plate. In addition, body regions which have already become stiff can be rehabilitated thereby.
- This seating device can be employed both for daily use and for therapeutic purposes.
- the seating device can offer possibilities to again achieve a natural upright posture, which can no longer be taken up due to reduced work and everyday tasks, and to avoid damage to the body—particularly to the spinal column.
- the seating device should create possibilities for the individual to recover an already lost sensitivity for dealing naturally with his/her own body as well as offering movement possibilities, which allow total freedom for constant movement when sitting.
- humans sit they must be in continuous movement and in constant play with the equilibrium if the natural oscillations of the body are to be continually allowed and tensions are not to build up in any way. Rigid sitting should be avoided, so that constant play with the equilibrium can take place and many natural bodily functions are not lost and are regained, respectively.
- a seat face must allow free tilting movements to all sides without disturbing resetting forces of the seat and the common rotating and swivelling point of the seat plate must lie directly above so that a natural extension of the spinal column beyond the coccyx is provided and thus constant transmission of movement can take place within the entire body.
