Adaptable frame carrier with freedom of movement along three axes for couches or seats

An adaptable frame carrier with triaxial freedom of movement for couches and seats, in which the freedom of movement is achieved in the x-, y- and z-direction by a system of spring loaded elements movable relative to one another, the couch or seat having a frame, the adaptable frame carrier comprising:

• at least one pressure resistant rolling plate;
• at least one dome shaped rolling body having a rolling radius R1 and operably engaging and rolling along said at least one pressure resistant rolling plate in the x- and y-direction;
• a frame connection plate operably mounted on the frame;
• an upper and a lower cylinder slidably engaging each other, wherein one of said upper and lower cylinders is connected to said frame connection plate in a spring loaded hinged configuration;
• a compression spring operably supporting said upper and lower cylinders against each other in a z-direction;
• and
• a connecting element connecting at least one of said upper and lower cylinders with said frame connection plate and being operable to make moveability between the x-, y- and z-direction interdependent on one another;
• wherein said at least one dome shaped rolling body and said upper and lower cylinders form an inner rolling element having a semicircular radius R2, said rolling radius R1 being greater than said semicircular radius R2.
