A tilting mechanism (1), preferably for a chair seat or similar article, comprises a rigid element (2) which, via a mounting means (3), can be attached to a chair base (4), a supporting means (6) adapted to the chair seat and pivotably connected in relation to said mounting means (3), resilient means (8a, 8b) so arranged between the supporting means (6) and the rigid plate (2) that the supporting means (6) can be tilted in relation to said rigid plate (2) under the influence of the resilient means (8a, 8b), as well as locking means (20, 21, 24) for adjusting the seat supporting means (6) to various tilting positions. To achieve a compact tilting mechanism offering separate or individual tightening of the tilting stiffness in the forward direction and the rearward direction without changing the seat angle in relation to the neutral it is, suggested that at least one of the resilient means (8a, 8b) be displaced in relation to the tilting shaft (5) of the supporting means (6). Appropriately, there may be provided a first resiliant means (8a) co-operating with a first portion of the rigid element (2), as well as a resilient means (8b) which co-operates with a second portion of the rigid element (2), each of the resilient means (8a, 8b) being displaceable independent of each other in relation to the tilting shaft (5) of the supporting means (6) by means of displacing means, preferably its own lever (10a, 10b).

Tilting mechanism (1), preferably for a chair seat or similar article, comprising a rigid element (2) which via a mounting means (3) can be attached to a chair base (4), a supporting means (6) adapted to the chair seat and pivotably connected in relation to said mounting means (3), resilient means (8a, 8b) which is so arranged between said supporting means (6) and said rigid plate (2) that such supporting means (6) can be tilted in relation to said rigid plate (2) under the influence of said resilient means (8a, 8b), as well as locking means (20, 21, 24) for adjusting said seat supporting means (6) to various tilting position, characterized in that at least one of said resilient means (8a, 8b) is arranged displaceable in relation to the tilting shaft (5) of the supporting means (6), for thereby adjusting the power influencing the resilient means (8a, 8b) and thereby the tilting stiffness to which the supporting means (6) is subjected during tilting.
