The invention claimed is: 1. A mobile joint (1) suitable for a sitting device, comprising a first and second joint element (10, 20), which are pivotally connected by a shaft (30), to allow tilting forwards and backwards of the sitting device caused by the displacement of the users weight, wherein t
The invention claimed is: 1. A mobile joint (1) suitable for a sitting device, comprising a first and second joint element (10, 20), which are pivotally connected by a shaft (30), to allow tilting forwards and backwards of the sitting device caused by the displacement of the users weight, wherein the mobile joint comprises a first and second parallel plate spring (18,19) with first and second ends, with an intermediate blocking element (11), wherein each plate spring (18,19) in the first end is connected to the first joint element (10), and in the second end is glidingly abutting the second joint element (20), the second joint element (20) is allowed to tilt forwards until the first plate spring (18) abuts the blocking element (11), the second joint element (20) is allowed to tilt backwards until the second plate spring (19) abuts the blocking element (11), the first and second plate spring (18,19) each having an axis of rotation that is displaced in relation to each other and the shaft (30). 2. The mobile joint (1) according to claim 1 wherein the springs (18, 19) abut curved faces (22, 23) on the blocking element (11) when deflected. 3. The mobile joint (1) according to claim 1, wherein the spring is adjustable by adjusting the distance from the axis of rotation of the shaft (30) to the connection of the springs (18, 19) to the first joint element (10). 4. The mobile joint according to claim 1, wherein the springs are made of fibreglass. 5. The mobile joint according to claim 4 wherein the fibreglass is reinforced by carbon and/or high-strength polymers. 6. The mobile joint according to claim 1, wherein the outside dimensions of the joint (1) are approximately 8 cm in height, 10 cm in width, and 8 cm in length. 7. The use of the mobile joint (1) formed according to one of the preceding claims in a chair comprising a seat device (100) and an underframe (200) wherein the mobile joint (1) connects the seat device (100) and the underframe (200). 8. The use according to claim 7 wherein the mobile joint (1) is integrated in the seat device (100).
