2. The balance chair according to claim 1, wherein the rotation and tilt element provides 360 rotation around and tilting in any direction about the element.

3. The balance chair according to claim 2, wherein the rotation and tilt element comprises or is operatively arranged to one or more devices providing elasticity for tilting in any direction about the element.

4. The balance chair according to claim 1, wherein the rotation and tilt element comprises or is operatively arranged to one or more devices or structure providing adjustable elasticity and range for tilting in any direction about the element, and resistance for rotation.

5. The balance chair according to claim 1, wherein the distance from the seat to the rotation and tilt element is in the range 0.25-1.25 m.

6. The balance chair according to claim 1, wherein the rotation and tilt element comprises a ball structure in a support, the ball structure is fixed to the height element, the height element with ball structure in the support is rotatable in the support and tilt able in the support, the support is coupled to the base, the height element comprises a lower part extending downward from the ball structure to a lower end within the base, the lower end is connected to the base with one or more devices providing adjustment of elasticity or resistance for tilting, adjustment of range of tilting and adjustment for rotation.

7. The balance chair according to claim 1, wherein the seat is rigidly fastened to an upper end of the height element, the height element is rigid from the seat to the rotation and tilt element, the rotation and tilt element and the base are separate or integrated structures comprising operatively connected springs and/or elastic elements.

8. The balance chair according to claim 1, wherein the rotation and tilt element comprises a separate adjustment device for resistance against rotation.

9. The balance chair according to claim 1, wherein the rotation and tilt element comprises a ball bearing or needle bearing arranged to the height element and a seat supporting the height element with ball or needle bearing.

10. The balance chair according to claim 6, wherein the height element comprises a lower part extending downward from the ball or ball bearing to a lower end within the base, the base comprises three or more legs at a lower end and/or a ring structure at a lower end, three or more elastic ropes arranged radially inwards from the legs or ring to a central element that can slide onto and be fastened to the lower part of the height element.

DETAILED DESCRIPTION

[0037] The embodiment of a balance chair 1 of the invention illustrated in FIG. 1 comprises a seat 2, an in substance vertical height element 3 supporting the seat 2, and a base 4 supporting the height element and seat. The height element 3 comprises a rotation and tilt element 5, arranged in a position in substance midway between the seat and a lower end of the base.

[0038] The height element 3 comprises a lower part extending downward from a ball or ball bearing 6 of the rotation and tilt element 5 to a lower end within the base, the base comprises three or more legs 7 and a ring structure 8 at a lower end. Within the base lower end are three or more elastic ropes 9 arranged radially inwards from the legs or ring of the base to a central element 10. Only one of the legs 7 and only one of the ropes 9 has a reference numerical, for clarity. The central element 10 can slide onto and be fastened to the lower part of the height element, the position of the central element together with length and elasticity of ropes and central element governs elasticity against and optionally range for tilting, the fit between central element and the lower part of the height element also can affect rotation resistance. The ropes and the central element, together with possible adjustment devices of the rotation and tilt element, and as working with the lower end of the height element, are examples of adjustment devices providing adjustable elasticity and range for tilting in any direction about said element, and resistance for rotation. The elastic ropes 9 as illustrated, as penetrating the ring structure 8, comprises adjustment or pre-tensioning devices on each rope, on the outside of said ring. The ring structure 8, or similar structure at higher elevation, restrict maximum tilting by stopping the movement of the lower part or end of the height element.

[0039] The distance from the seat to the rotation and tilt element is in the range 0.25-1.25 m. Said distance is fixed or can be adjusted with an adjustment element on the height element, for example a telescopic element.

[0040] FIG. 2 illustrates the rotation and tilt element 5 as the operative connection between the rigid height element with seat in an upper end, and the base providing a stable foot of the chair. The height element with seat in upper end can rotate around the longitudinal axis of the height element and tilt about the rotation and tilt element. A ball or half ball like structure 6, not clearly visible, rests in a support or seat on top of the base. The ball or half ball like structure is penetrated by the heightenth element. Said ball structure is fastened to the support by a flange structure 11, and bolts 12 can be used to adjust or affect the resistance against rotation and tilting, in addition to the adjustment means elastic ropes 9 and central element 10 illustrated in FIG. 1. The half ball like structure is preferably slightly conical on top, facing upwards in a neutral non- tilted orientation, the conical shape restricting the maximum tilting.

[0041] The balance chair of the invention provides balance training and training of core muscles, at adjustable precision, level or extent, by adjusting the adjustment devices to fit the purpose or replacing tension or restriction elements. For training of riding skills, the instability is adjustable, the tempo can be from extremely slow to extremely fast. For horse riding training, the level of precision in the training is far above what is achievable with a horse, a large number of repeated training steps can be performed much faster, providing more precise and faster auto-correction-skills for horse riding. These effects for training of horse riding skills have been confirmed unambiguously by test users at different levels. The balance chair of the invention can comprise any feature as here described or illustrated, in any operative combination, and each such operative combination is an embodiment of the balance chair of the invention.
