Abstract

DC60 (12/03/47) This invention relates to a spring-resistant mobile joint, as defined by several claims, consisting of 2 coupling parts (10, 20) welded. Can be rotated around the axis with the axis (3) and are forced to limit the rotation of each other. Between positions Both tilts are fully tilted with the bar block (11) so that the seat portion Can lean as a result of Scroll to change the position of the user's weight. Classified Thanks to the fact that spring resistance is given Occurs with a sheet spring (18, 19), which is connected to 1 of the coupling element (10), where the spring is bent along The axis is placed at a distance from Axial rotation axis (30) This invention relates to a motion coupling with spring resistance, as defined in the multiple claims consisting of 2 coupling parts (10, 20). Which is connected to the rotation around the axis with the axis (3) and are forced to limit the rotation of each other. Between locations Both tilts are fully tilted with the bar block (11) so that the seat portion Can lean as a result of Scroll to change the position of the user's weight. Classified Thanks to the fact that spring resistance is given Occurs with a sheet spring (18, 19), which is connected to 1 of the coupling element (10), where the spring is bent along The axis is placed at a distance from The axis of rotation of the axis (30).

Claims (8)

1. A movable joint (1) with spring resistance for a seat assembly consists of two articulated parts (10, 20) which are rotatably connected to an axis (3) and are constrained to limit each other's rotation between the two extreme tilt positions by a bar (11) so that the seat assembly can tilt as a result of the shifting of the user's weight. This is characterized in such a way that spring resistance is provided by leaf springs (18, 19) connected to one of the articulated parts (10), which are bent along an axis positioned away from the axis of rotation of the axis (30). 2. The movable joint (1) as described in claim 1 is characterized in such a way that the springs (18, 19) strike against the curved butt faces (22, 23) on the barring device (11) when bent. 3. A movable joint (1) according to one of the claims 1-2, which is characterized in such a way that the spring can be adjusted by adjusting the distance from the axis of rotation of the shaft (30) to the spring fixation part (18, 19). 4. Movable joints in accordance with any one of the claims 1-3, which are characterized in such a way that the springs are made of glass fiber material. 5. Swivel joints according to claim 4, which are characterized in such a way that the glass wire material is reinforced with carbon and/or Kevlar. 6. A movable joint in accordance with any one of the claims 1-5, which is characterized in such a way that the outside dimensions of the joint (1) are approximately 8 cm x 10 cm x 8 cm (height x width x length). 7. Use of a movable joint (1) which is assembled in accordance with one of the aforementioned claims in a chair that includes the seat assembly (100) and the underframe (200), where the movable joint (1) connects the seat assembly (100) to the underframe (200). 8. Use under claim 6 in which the movable joint (1) is incorporated into the seat assembly (100).
