In an adaptable frame carrier with freedom of movement along three axes for couches and seats, the freedom of movement in the X, Y and Z directions is ensured by a system of elements that can be moved and supported on springs in relation to one another. A coupling element makes the movements in the X, Y and Z directions interdependent. The invention is characterised in that the frame carrier has at least one cap-shaped rolling body (3, 8) that rolls on a pressure-resistant rolling plate (2) in the X or Y directions, in that the frame carrier has two cylinders (6, 7) that slide inside one another and are supported against each other in the Z direction by a compression spring (4), and in that one of the sliding cylinders (7) is resiliently joined to the frame (18) of the couch or seat by a connection plate (13).
Dans ce support adaptable librement mobile le long de trois axes pour cadres de couchettes et de sièges, la liberté de mouvement dans les directions X, Y et Z est assurée par un système d'éléments mobiles et élastiques les uns par rapport aux autres. Un élément d'accouplement rend mutuellement dépendants les mouvements dans les directions X, Y et Z. L'invention se caractérise en ce que le support comprend au moins un corps de roulement (3, 8) en forme de calotte qui roule dans les directions X ou Y sur une plaque (2) de roulement résistante à la pression. Le support comprend deux cylindres (6, 7) qui glissent l'un dans l'autre et sont soutenus l'un sur l'autre dans la direction Z par un ressort de compression. Un des cylindres (7) coulissants est relié de manière élastique et articulée au cadre (18) de la couchette ou du siège au moyen d'une plaque (13) de raccordement au cadre.
