Abstract
An office chair has a seating element with an upright tubular element (3) and a base, the seating element being connected to the base by means of the support element (1) so as to be swiveled and reset. Rubber buffers (19, 24) are provided between a connecting element (2) of the base, ring discs (11) and (17) and a tubular element (8) extending from the seating element downward and allow an oscillating movement of the seating element. The rubber buffers at least partially enclose the connecting element (2), thereby retaining the same. A pneumatic spring (4) allows to adjust the height of the seat. A thumb screw (16) allows to adjust the restoring force by compressing the rubber buffers (19, 24) to a greater or lesser extent.
Claims14
A supporting element comprising a first tubular piece at a lower part of the supporting element and a conical second tubular piece at an upper part of the supporting element, for connecting a jointing element adapted to bear a seat with a base, wherein:
- the jointing element is formed in the base for connecting the base with the first tubular piece, the jointing element comprising a hollow cylinder,
- the first tubular piece being inserted into the hollow cylinder of the jointing element and extending beyond open ends of the hollow cylinder of the jointing element,
- an upper and a lower disc-shaped stopper being fixed above and below the first tubular piece, respectively, the disc-shaped stoppers having an outer diameter being greater than the open ends of the hollow cylinder of the jointing element,
- resilient elements are disposed between the upper disc-shaped stopper and the jointing element, between the lower disc-shaped stopper and the jointing element, and between respective ends of the hollow cylinder of the jointing element and the first tubular piece, and
- the conical second tubular piece is supported free to be tilted and returned at the jointing element by means of at least one of the resilient elements.
