ABSTRACT:
A device for coupling two units to each other with at least five connecting elements (18,20,22,24,26) whereby the respective first end thereof can be hingeably connected to respectively one connection point (30,32,34,36,38) of one unit and whose other end can be hingeably connected to a respective connection point (40,42,44,46,48) of the other unit. One length-adjustable connecting element (18) is exclusively provided, the element being arranged in a substantially central position in the upper area of the device (12). Two connecting elements (24,26) are provided in the lower area of the device (12). Two length-adjustable connectable elements (20,22) are coupled substantially at the connection point (36;38) of a connecting element (24,26) arranged in the lower area of the device (12) on one unit, and in a lower area (42,4′) of the other unit. A length-adjustable stabilizer element (28) is also provided. The element cooperates, with at least one of the two connecting elements (24,26) arranged in the lower area, with at least one connection point (38,46;36,48) and/or with at least one unit.
