A seating unit comprising two adjacent and mutually pivotal support elements (3, 4) pivotal between an initial position and a maximal flexed position. A spring element (12) is secured between the support elements (3, 4) and provided with a spring means (18, 18') biassing the support elements (3, 4) into the initial position. The spring element (12) comprises a base member (13) arranged in the adjacent area of the support elements (3, 4) and engagement means engaging each their own support element (3, 4). At least one engagement means extends from the base member (13) into a cavity (14, 15) in one of the support elements (3, 4) such that the support elements (3, 4) may pivot relative to each other. Said at least one engagement means is provided with a rigid stop means (17, 17') projecting from the base member (13) and defining the maximum flexed position. The at least one engagement means is further provided with a spring means (18, 18'; 68) to restore the support elements (3, 4) to their initial position. |
