Abstract: A swivelling device to adjust the swivelling of two mechanical parts includes a flexible coupling placed between the two mechanical parts which have opposed interior surfaces facing each other. The opposed external surfaces of the swivelling device are contiguous with respective opposed interior surfaces of the two mechanical part and providing a flexible cushion between the two parts. The method for positioning the flexible coupling includes the operations of drilling a hole into one of the mechanical parts and then injecting a flexible material through the hole to form a flexible coupling between the two mechanical parts.

Abstract: A device to adjust the swivelling of two mechanical parts and a method for making this device are disclosed. The device comprises a flexible coupling placed between the two parts and acting as a ball joint between the two parts and means to adjust the distance between the two parts, these means being located at a given distance from the joint. The method for positioning the flexible coupling between the two mechanical parts comprises the following operations: a hole is drilled into one of the mechanical parts and the material of the flexible coupling is injected through the hole.
