Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side defroster device for a vehicle.

BACKGROUND OF THE INVENTION Examples of conventional vehicle door side defroster devices include those shown in FIGS. 1a and 1b, for example. That is, in this door blowing side defroster device, a side defroster 2 communicating with a hot air source is led to the end of an instrument 1, one end of a grommet 3 is connected to this duct 2, and an inner panel 5 of a door 4 is connected to the inner panel 5. A duct 8 is formed by the door trim 6 and the resin cover 7 between the installed door trim 6 and the door trim 6.
An opening 9 which connects with the other end opening of the grommet 3 when the door 4 is closed, and an outlet finisher 10 are provided above. The warm air led from the hot air source by the duct 2 passes through the grommet 3 and reaches the duct 8, and is blown out from the outlet finisher 10 to clear the fog on the side window 11.

However, in the case of such a conventional door blow-out side defroster device, the duct 8 is provided between the door trim 6 and the door inner panel 5, so it is not suitable for cars where the door trim does not extend to the door waist portion. There was a problem that it could not be installed.

Further, since the air outlet finisher 10 was attached to the door trim 6 with a large installation error, there was a problem in that it was difficult to obtain an appropriate air outlet direction.

This invention was made by focusing on such conventional problems, and a duct is provided in the door inner panel and connected via a grommet to a side defroster duct that communicates with a hot air source and is guided to the end of the instrument. An object of the present invention is to provide a side defroster device for an automobile that can be applied to vehicles with or without door trims by providing an outlet above a duct for blowing hot air to a side window.

The present invention will be explained below based on the drawings.

FIG. 2 is a diagram showing an embodiment of the present invention.

Note that parts that are the same as those in the prior art are given the same reference numerals and their explanations will be omitted.

First, to explain the structure, the duct 8 is formed by the door inner panel 5 of the door 4 and the reinforcement 12 welded to the inner surface of the door inner panel 5. This duct 8 is provided in the front-rear direction along the waist portion inside the door inner panel 5. The door inner panel 5 is provided with an opening 9 that joins the other end opening of the grommet 3 and an outlet finisher 10 in a portion located above the duct 8. Other structures are the same as before.

Next, the action will be explained.

The warm air guided to the instrument end by the side defroster duct 2 passes through a grommet 3, an opening 9 provided in the door inner panel 5, and is guided into the door 4. This warm air passes through a duct 8 formed by the door inner panel 5 and the rain force 12, and is blown out from an outlet finisher 10 attached to the door inner panel 5 and hits the side window 11, thereby defrosting the side window 11. be.

Therefore, it can be applied to vehicles with or without door trims. Also, the outlet finisher 1
0 is directly fixed to the door inner panel 5, so that an appropriate blowing direction can be obtained and a good sunny pattern can be obtained. Furthermore, since the duct 8 is provided in the front-rear direction along the waist portion inside the door inner panel 5, the warm air guided into the duct 8 is not cooled, and a sufficient amount of air can be secured.
This means that the defrost action is effectively performed.

FIG. 3 shows another embodiment.

In this embodiment, instead of forming the duct 8 provided in the door 4 from the door inner panel 5 and the rain force 12, it is formed from a rubber boot 13 and is bonded and fixed to the door inner panel 5 and the presser foot 14. Note that the grommet 3 is integrally molded with the rubber boot 13.

Since the operation is the same as in the first embodiment, the explanation will be omitted.

FIG. 4 shows yet another embodiment.

This embodiment differs from the second embodiment shown in FIG.
0 is integrally molded with the resin boot 15.

The operation in this case is also similar to that of the previous embodiment, so the explanation will be omitted.

As explained above, according to this invention,
We have installed a duct in the door inner panel that connects via a grommet to the side defroster duct that communicates with the hot air source and is guided to the instrument end, so the side defroster device can be installed with or without a door trim, and it is easier to install than the door trim. Since the air outlet is attached to the door inner panel, which is a component of the duct with little error, it is possible to obtain an appropriate wind direction and a good side window clearing pattern. Because they are installed in the front-rear direction along the waist, in other words, they are installed efficiently in the necessary areas, the guided warm air is not cooled, there is little ventilation resistance, and a sufficient amount of airflow can be ensured.
The effect is that the defrost action is effectively performed.
