Abstract (en)
[origin: US2015257537A1] 1. Piece of seating furniture and fitting therefor. 2.1 It is known for a piece of seating furniture to have a base (20) and a seat unit (10), wherein the base and the seat unit have provided between them a pivot bearing (30) comprising a base-side bearing device (34) and a seat-unit-side bearing device (32), by means of which the seat unit (10) can be rotated about a vertical axis (2) in relation to the base (20), and the pivot bearing has a switchable blocking device (40, 50a, 50b, 60), by means of which the rotary movement capability of the bearing devices (32, 34) in relation to one another can be blocked. 2.2 It is proposed to use, for this purpose, a blocking device (40, 50a, 50b, 60) which comprises the following components: an encircling blocking surface (40) on a first of the two bearing devices (34), at least one torsion spring (50a, 50b) which wraps around the blocking surface (40), is fastened on the second bearing device (32) and has an internal diameter which is variable in dependence on the stressing state, and a switching device (60), by means of which the torsion spring (50a, 50b) can be subjected to stressing and relieved of stressing, wherein the torsion spring (50a, 50b), in the stressed or relieved-of-stressing state, butts against the blocking surface (40) and thus prevents relative rotary movement between the bearing devices (32, 34).
