- the length of the Chair column can be adjusted by the chair column inserted more or less far into the connecting element and is locked with the ribs of the connecting element. On this is a gradual adjustment of the chair column length and thus the basic position of the seat is possible, however this type of adjustment is expensive.
- the invention has for its object an adjustment the basic position of the seat of chairs create that is structurally simple and easy to use.
- the invention is based on a device of the type mentioned Kind with the characteristics of the characterizing part of the claim 1 solved.
- the sleeve tapers downwards and the connecting element an appropriately tapered Have outside diameter.
- the fit between the connecting element and the sleeve also serves in addition, the once selected setting between the connecting element and secure chair column.

This is due to the snug fit between Connection element and sleeve of the chair foot a clamp connection between the connecting element and the chair column a corresponding length compensation of the spiral is possible.
- the external thread for the connecting element must be can not be arranged directly on the chair column, but can also be molded into a plastic tube with which the chair column is encased.
- a plastic tube offers the The advantage that conventional chairs can be adjusted without them according to the basic position with the adjustment mechanism the invention can be retrofitted.
- the manufacture of such a plastic tube can be done from two half-shells.
- the solution according to the invention for the continuous adjustment of the The basic position of the seat height of office and work chairs is highly variable with extremely low design effort enables the user of the chair to easily do this any number of times according to their respective wishes or the given Adapt workplace requirements.

- This Sleeve 14 is in a correspondingly conically shaped sleeve 15 of the base 13 insertable.
- the sleeve 14 limits a central through opening in the star base 13.
- the connecting element 14 has on its inside one from FIG. 1 not visible internal thread that is in the external thread 11 of the tube 10 is insertable.
- blind slots 17 receives the connecting element 14 has a certain elasticity, which after Insert the connecting element 14, the tube 10 and the therein arranged chair column in the sleeve 15 of the star base 13 a clamp connection between the connecting element 14 and the tube 10 causes, so that the basic setting of Seat height can no longer be adjusted automatically. That too Tube 10 is provided with blind slots 18 which are analog Way a clamp connection between the tube 10 and one enable the chair column inserted in it.
- Fig. 2 shows the connecting element 14 'according to the invention, in the form of a spiral, the outer diameter also tapers conically downwards and thus also for use in the conically shaped sleeve 15 of the Base 13 according to FIG. 1 is suitable.
- On the inside of the Spirals are either a circumferential depression or elevation 16 provided, which thus form an internal thread that in the external thread 11 of the tube 10 according to FIG. 1 can be carried out.
- 2 is also an interference fit with the connecting element 14 ' possible between connecting element 14 'and tube 10.
- To Inserting the element 14 'in the sleeve 15 is on the External surface of the spiral 14 'acting pressure to a change in length of the spiral, which makes it tighter around the Tube 10 closes and thus the set seat height position locked.
