Mobile joint with several stable positions, suitable for use in furniture
First Claim
1. A mobile joint (1) for a seating construction for mounting between a seat device (100) of a seating construction and a support (200) for said seat device (100), comprising at least two joint elements (10, 30) wherein each joint element is pivotable to a limited degree in relation to each joint element that it is connected to, permitting the mobile joint (1) to pivot between two extreme positions in order to allow a tilting movement of the seat device (100), effected by the user'"'"'s weight displacement, wherein the mobile joint contains a first joint element (10) mountable at a first end to the support (200) and at a second end only mounted pivotally to a first end of a middle joint element (20) at a first rotational axis (40), and further containing a second joint element (30) mountable at a first end to the seat device (100) and at the second end only mounted pivotally to a second end of the middle joint element (20) in a second rotational axis (50), wherein the said rotational axes (40, 50) are horizontally displaced in relation to each other, and whereby the joint (1) assumes a stable tilting position between the two extreme positions when the user'"'"'s center of gravity is above a point between the first and second rotational axes;
- wherein at least two of the joint elements (10, 20, 30) are spring-loaded in relation to each other by a torsion spring.

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