These mechanical supports comprise a semi-rigid hose, or a generally reinforced spring. They are equipped with a mechanical end piece that interfaces with a bearing structure at one end and with a device to be supported at the other end.
A semi-rigid hose-based support is used to obtain a fixed positioning of a device in space. Spring-based support is used to protect a device when it collides with an object.
The semi-rigid hose consists of a spring and a profile. The latter is inserted between each turn of the spring which allows to give it its own mechanical characteristics and to keep a given position in space.
