ABSTRACT:

TECHNICAL FIELD OF THE INVENTION
The invention relates to a sun visor assembly with a flat, long body.
BACKGROUND OF THE INVENTION
Modern sun visors utilize catch springs, which produce a particular folding moment and a latching function of the sun visor body in coordination with the axle of the sun visor. In these systems, the catch spring is generally located inside the sun visor body and is fastened to the bearing of a stabilizing frame. Because of this construction, these sun visors exhibit a cross section whose thickness can be calculated by summing the diameter of the axle, the wall thickness of the bearing, and the thickness of the thinnest possible material. The cross section is undesirable by the client, who wants a thinner sun visor.
The objective of the invention is to provide the client with an improved sun visor, in particular, a sun visor with a relatively thin body, which is additionally distinguished by improved utility features.
SUMMARY OF THE INVENTION
In accordance with the invention, the bearing device is now installed outside of the sun visor body both for the folding movement and for the swinging movement. This has the special advantage that the sun visor can now be designed significantly thinner than in conventional practice. Another advantage of the invention is that the catch spring could now likewise be moved outside the body, so that an expensive extra finishing is no longer needed for the surface of the sun visor. Such finishing had to be performed to counteract corrosive loads, especially in the case of plastic sun visors, for which wet steam is used to foam the foaming material. Even the expense for the required lubrication (of the axle and catch spring) is considerably reduced because handling is much easier and placement is improved, so that a smaller amount of lubricant is needed. There are even fewer rejects, because there is fewer opportunities for grease residue to soil the sun visor. Further, a square mirror, which many customers desire, can be used because more free space is available for a larger mirror on the body of the sun visor. Finally, these advantages also have a very positive and favorable effect on the manufacturing process and the quality, which can be noticed in lower manufacturing costs.
