Abstract

<P>PROBLEM TO BE SOLVED: To provide an inexpensive and presentable vehicle door capable of enhancing upper portion strength by eliminating a bezel opening of a door trim upper portion and decreases the number of parts by eliminating use of a defroster bezel and its fitting process. <P>SOLUTION: The air introduced from an inlet opening ahead of a door trim is made to spray toward a window glass from the upper portion of the door trim through the defroster pipe when the door is fully closed. A required section of the upper portion 2 of the door trim 1 is formed at the air jetting portion 3 where countless microscopic air jetting holes 3a are arranged, and a front end blowing-off opening 4a of the defroster pipe 4 is made to face the lower portion of the air jetting portion 3. Thus the introduced air is sprayed over the window glass from the countless microscopic air jetting holes 3a of the air jetting portion 3. <P>COPYRIGHT: (C)2004,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a defroster which, when a door is closed, introduces air introduced through an air inlet provided in front of a door trim covering an inner panel. The present invention relates to a vehicle door in which a defroster device that can be sprayed toward a window glass through a pipe to prevent fogging is incorporated. 2. Description of the Related Art In a conventional vehicle door, when the door is closed, air is introduced from an air introduction port provided in front of a door trim covering an inner panel, and the air is introduced through a defroster pipe. A defroster device is incorporated which blows air from an air blowout portion provided in an upper portion of the door trim toward a window glass to prevent fogging. However, the air blowing portion of this type of vehicle door has a bezel opening in the upper portion of the door trim and a defroster bezel fitted to the opening, and is supplied from the above-described inlet to the tip of the defroster pipe. Normally, air is blown toward the window glass through the defroster bezel described above.
It is necessary to provide a bezel opening in the upper part of the door trim, but this bezel opening is large enough to affect the strength of the upper part, causing a problem in the durability of the door trim itself, and Since the defroster bezel, which is another component, is fitted into the opening, the number of components is increased and a fitting process is required, resulting in an increase in cost. [0003] The present invention seeks to solve the above-mentioned conventional problems.
By eliminating the bezel opening in the upper part of the door trim and increasing the strength of the upper part, the durability of the door trim itself can be increased, and by eliminating the defroster bezel, the number of parts is reduced and the fitting process is eliminated, It is an object of the present invention to provide an inexpensive and well-formed vehicle door capable of reducing costs. [0004] In order to solve the above-mentioned problems, the vehicle door of the present invention, when closed, air introduced from an inlet in front of the door trim through a defroster pipe. In a vehicle door that can be sprayed toward a window glass, a required portion of an upper portion of a door trim is formed in an air ejection portion provided with countless fine air ejection holes, and a defroster is provided below the air ejection portion. With the front end outlet of the pipe facing, the introduced air is blown toward the window glass from the myriad of fine air outlets of the air outlet. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS. Door body 10 in vehicle door of the present invention
Is an inner panel (not shown) covered with a door trim 1 like a conventional door body, and an air inlet 6 provided in front of the door trim 1 when the door is closed.
Is communicated with a ventilation hole provided on a side surface of an instrument panel (not shown) connected to an air supply source, and air introduced from the introduction port 6 is blown out from an air blowing portion of the upper portion 2 of the door trim 1 through a defroster pipe. The door trim 1 which houses the door body 10 is a trim board formed of a harmless and tough synthetic resin material such as polyamide or polyolefin, and is covered with a skin. In front of the upper portion 2 and other required portions, an air ejection portion 3 having countless fine air ejection holes 3a is formed as an air ejection portion. In addition, the above-mentioned air ejection hole 3a is
In order to obtain an efficient defroster effect and avoid a decrease in the strength of the upper part, the hole diameter is preferably 1 mm.
Hereinafter, it is particularly preferably 0.5 mm. [0006] 4 is a door trim 1 covering the inner panel.
The defroster pipe 4 is provided on the back side of the vehicle. The base end of the defroster pipe 4 is located at a portion in front of the door trim 1 which comes into contact with the side surface of the instrument panel of the vehicle when the door body 10 is closed. The air outlet 6 is connected to the air inlet 6 provided, while the expanded front end outlet 4a faces the lower portion of the air jetting section 3 and the door body 10 is closed. Only when the air is introduced, the air inlet 6 is communicated with the vent hole on the side surface of the instrument panel, so that air is introduced into the defroster pipe 4 from the inlet 6 and the defroster pipe 4 Efficient spraying is performed toward the window glass from the myriad of fine air ejection holes 3a of the air ejection portion 3 in the upper portion 2 of the door trim 1 facing the front end outlet 4a. Is constructed sea urchin. The tip outlet 4a of the defroster pipe 4 is provided below the upper portion 2 of the door trim 1 with an air ejection portion 3 formed of countless fine air ejection holes 3a provided in the upper portion 2.
May be in or out of contact with the lower surface of the upper portion 2 as long as the front end outlet 4a is in close contact with the lower surface of the upper portion 2 via an elastic sealing material or the like. It is preferable that air be more efficiently ejected from the air ejection holes 3a. [0007] With this configuration, the air inlet 6 in front of the door trim 1 is in contact with the side surface of the instrument panel only when the door is closed, and communicates with the air hole connected to the air supply source. In addition, when fogging is stopped, air supplied from an air supply source is supplied to the inlet 6.
Although it is introduced into the defroster pipe 4 and blows out from the tip outlet 4a in the same manner as in this type of conventional vehicle door, the tip outlet 4a of the defroster pipe 4 is connected to the upper part of the door trim 1 as described above. Since the air blows from the end outlet 4a to the air outlet 3 formed by the myriad of fine air outlets 3a provided in the upper portion 2 below the upper portion 2, the air blows from the air outlet 3a.
Are efficiently sprayed toward the window glass through the myriad of fine air ejection holes 3a, whereby an accurate defroster effect can be obtained. In addition, the air ejection portion 3 composed of innumerable fine air ejection holes 3a provided at required portions of the upper portion 2 of the door trim 1 is formed by arranging the air ejection holes 3a and surrounding the air ejection holes 3a. The combination with a ridge or a groove formed on the surface of the upper portion 2 makes it possible to obtain a decoratively excellent one, so that the aesthetic appearance can be made favorable. As is apparent from the above description, according to the present invention, a required portion of the upper portion of the door trim is formed in an air ejection portion provided with countless fine air ejection holes. Since the tip of the defroster pipe faces the lower end of the defroster pipe and the introduced air is blown toward the window glass from the myriad of fine air ejection holes of the air ejection part, the upper part of the door trim is There is no need to provide a bezel opening, which increases the strength of the upper and increases the durability of the door trim itself.
The number of parts can be reduced by the amount of removing the defroster bezel, and the assembling process such as the fitting process of the defroster bezel can be eliminated, so that the cost can be reduced, and the vehicle door is inexpensive and has a good appearance. Can be provided. Accordingly, the present invention is extremely large in that it contributes to the development of the industry as a solution to the problems of this type of conventional vehicle door.
