JPH01237223A - Header garnish for containing sunvisor - Google Patents

Abstract

PURPOSE:To perfectly eliminate switch mechanisms for preventing overheat or lighting a sunvisor by providing a position detecting switch for judging whether the sunvisor is in using position or containing position to a garnish. CONSTITUTION:A magnet 4a is buried in a proper position of a sunvisor 2, and a normal close lead switch 4b is arranged in a hollow section 1b of a garnish 1 corresponding to the magnet 4a thus constituting a switch 4. When a lighting unit 3 is connected through the switch 4, the magnet 4a faces the lead switch 4b when the sunvisor 2 is housed thus interrupting the power source and stopping power supply to the lighting unit 3. Under a state where the sunvisor 2 is brought to the use position, the magnet 4a moves and separates from the lead switch 4b which is turned on and connected through the switch 4 to the power source thus lighting the lighting unit 3 automatically.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a header carnish provided in front of the ceiling of an automobile for storing, for example, a sun visor, a room lamp, a pine lamp, and the like.

[Conventional technology]

In a conventional header garnish of this kind, for example, a blinking switch for the room lamp is also provided at the same time, and the functions are concentrated so that all electrical equipment installed on the header garnish can be operated. This is why it is sometimes referred to as an overhead console.

[Problem to be solved by the invention]

However, in recent years, more and more sun visors, especially those for passenger seats, are equipped with mirrors called vanity mirrors, and along with this, lighting devices have also come to be attached to the sun visors. . At this time, if you forget to turn off the lighting device and store it in the header garnish while it is on, there is a risk of overheating or ignition. It has been proposed that a safety switch that opens and closes when the cover is opened and closed is installed separately from the lighting switch, and the power is cut off when not in use, but for this purpose, it is originally handled in the header garnish. The wiring process, etc., which should be performed, extends to the inside of the sun visor, resulting in problems that need to be solved, such as complicated processes and increased costs.

[Means to solve the problem]

The present invention provides a header garnish, which is installed in the front of the ceiling of an automobile and houses a room lamp, a sun visor, etc., as a specific means for solving the above-mentioned problems. By providing a header garnish for storing a sun visor, which is characterized by being provided with a position detection switch that is turned on and opened at the stored position, the wiring process for the switch etc. does not extend to the inside of the sun visor. This solves the conventional problems mentioned above.

【Example】

Next, the present invention will be explained in detail based on an embodiment shown in the drawings. What is indicated by the reference numeral 1 in FIG. 1 is a header garnish for storing a sun visor (hereinafter simply referred to as a car header garnish). A recess 1a that is installed near 12 and houses the sun visor 2.
Although not shown, a room lamp and the like are also installed. Here, the sun visor 2 is provided with a mirror (not shown), and is also provided with a lighting device 3 and a cover 3a, but according to the present invention, the sun visor 2 is provided with a mirror (not shown). The light switch 4 is provided in the hollow part lb side of the garnish 1, and has the simplest configuration, with only wiring for supplying power to the lighting device 3, without any flashing or security switches as seen above. It has become something that can be done. To explain this blinking switch 4 in more detail, a magnet 4a is embedded in an appropriate position of the sun visor 2, and a normally closed reed switch 4b is provided in a hollow portion 1b of the garnish 1 facing the magnet 4a. By connecting the lighting device 3 to a power source via the blinking switch 4, the magnet 4a and the reed switch 4 are connected to each other when the sun visor 2 is stored.
b faces each other, the power source is cut off, and no current is supplied to the lighting device 3. In the case shown in FIG. 2, the sun visor 2 is in the use position, and the sun visor 2 rotates around the rotation axis 2a, and at the same time, the magnet 4a also moves and separates from the reed switch 4b. As a result, the reed switch 4b detects that the sun visor 2 is in the use position and is turned on, and the lighting device 3 connected to the power supply via the flashing switch 4 as described above automatically lights up. Become something. In this example, in order to clearly show the main parts of the present invention,
For example, the locking mechanism normally provided on the garnish 1 and sun visor 2 of this plate during storage is omitted; however, as shown in FIG.
A relatively strong magnet 41a is arranged on the tip side of the rotation,
For example, as shown in FIG. 4, on the garnish 1 side, a reed switch 4b similar to that of the previous embodiment and an adsorption plate 4C made of a magnetic material such as an iron plate are installed together, so that the switching action and the locking action can be performed. It will serve both purposes at the same time. Here, in the case 1 of the present invention, simply by setting the sun visor 2 from the storage position to the use position, the lighting device 3 is automatically turned on regardless of day or night. Although it also serves as a safety switch, the inventor's investigation into actual usage conditions found that in most situations, the interior of the vehicle is dark and no inconvenience was observed due to the automatic lighting.

【Effect of the invention】

As explained above, according to the present invention, by providing the garnish with a position detection switch that determines whether the sun visor is in the use position or the retracted position, the sun visor side has a function for overheating prevention or flashing. There is no need to provide a switch mechanism at all, and the structure of the sun visor can be simplified without compromising functionality in the slightest, resulting in an excellent reduction in man-hours and costs. In addition, by using a magnet and a reed switch as the position detection switch, the magnet can also be used as a locking mechanism for the sun visor, which has the effect of further simplifying the structure.
