DESCRIPTION:
BRIEF SUMMARY
This invention concerns a sun visor for motor vehicles.
All motor vehicles today are equipped with such sun visors. It is also known that devices can be provided in the interior of the vehicle for evaporation of liquid agents to influence the interior air. These are used to deodorize the interior air or enrich it with perfumes or active agents that improve well-being or have a medicinal effect such as eucalyptus oil for inflammatory diseases of the respiratory tract. The evaporation results are especially good when the devices are placed in the path of the air flow of the interior circulation, which is the case when placed above an air outlet grid on the dashboard. In addition, an evaporation device is also known which can be mounted by means of suction cups on the interior of the windshield where they are then in the path of the air stream directed against it.
There are a variety of disadvantages to this implementation. An evaporative device mounted directly above an air outlet grid greatly decelerates the flow of air and evaporates too rapidly so the release of active agent is initially too great and then decreases very rapidly to a minimum. An evaporative device attached to the windshield is exposed to especially intense sunlight which in turn results in excessive evaporation. In each case the devices constitute a foreign body which projects more or less from the windshield and can be detached or shifted by an inadvertent brusque movement and rarely fits well with the design of the motor vehicle interior.
This invention is based on the problem of eliminating all these shortcomings in the simplest possible way.
This invention consists of the fact that the visor has a hollow space that is open on at least one side so the evaporative device can be inserted into it and at least partially recessed. The visor and evaporative device are thus combined to one component.
In this way the evaporative device is accommodated discretely and is also protected against harmful sunlight exposure. It is still in the path of the air circulation in front of the windshield, but the air flow is not so strong in the area of the sun visor that it can cause excessively rapid evaporation. From the sun visor the air stream is pointed directly at the driver or passenger so these persons are directly affected by the air enriched with the active agent, which is especially advantageous in the case of active agents with a medicinal or curative effect. The housing of the evaporative device is thus built into the sun visor panel in manufacturing the sun visor so assembly cost is very low.
The figures show practical examples of this invention, namely:
FIG. 1 shows a longitudinal section of an evaporative device built into a sun visor.
FIG. 2 shows a lower view of the device.
FIG. 3 shows a cross section A--A according to FIG. 1.
FIG. 4 shows a schematic diagram of the sun visor according to this invention in the assembled state.
FIG. 5 shows one variation in longitudinal section.
FIG. 6 shows the lower view according to FIG. 5.
FIG. 7 shows cross section B--B according to FIG. 5.
FIG. 8 shows a longitudinal section of a lengthwise half of an evaporation device with an alternative rotating mount.
FIG. 9 shows the cross section C--C according to FIG. 8.
FIG. 10 shows the longitudinal half of the device that is the complement to FIG. 8 but equipped with a different rotating mount.
FIG. 11 shows the cross section D--D according to FIG. 10 on an enlarged scale.
In accordance with FIGS. 1 to 3, the sun visor 1 of the sun visor is provided with a lengthwise opening 2 which holds the housing for the device consisting of shell-shaped part 3 inserted from one side and frame-shaped part 4 inserted from the other side. These parts extend with their side walls 3a and 4a into opening 2 and with their peripheral edges 3b and 4b they cover the peripheral areas of the opening. The mutual mounting of the peripheral walls 3a, 4a can take place by means of a mutual locking or screw connection (not shown) which should be designed in such a way that the housing
