摘要

The present invention relates to a mobile joint (1) for a seating construction, especially a chair, for mounting between a seat device and a base and comprising at least two joint elements (10 and 30) which are reciprocally restricted pivoted between two extreme positions to allow tilting movement of the seating construction effected by the users weight displacement and comprising two outer joint elements (10 and 30) which are pivoted related with a middle joint element (20), wherein the rotational axis (40 and 50) between the two joint elements (10 and 30) and the middle joint element (20) is displaced in relation to each other in the horizontal direction and whereby the joint (1) may assume a stable tilting position between the two extreme positions.
