ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention generally relates to a method of fabricating a door trim of a vehicle, and more particularly, to a fabrication method in which the ornamental cloths can be firmly attached to the center part of the door trim.
Generally, the automotive door trims have an ornamental member such as cloth, carpet, and others on appropriate parts of the door trims, on the purpose of ornamentation or comfort feeling.
A prior art of mounting such an ornamental member on a door trim is disclosed in U.S. Pat. No. 5,236,534, wherein a non-preformed decorative member is contact-bonded and fixed by use of a mold for contact bonding to the main body of a door trim according to its complicatedly curved surface, excessive portions of the decorative member are cut away by a fusing blade attached to a bottom tool for contact bonding, and the decorative member is subjected to a peripheral/end edge treatment by a press-in bar.
By the way, when the door trim main body is placed on a surface of a bonding upper die, a vacuum device is needed for holding the main body on the upper die, which result in a high cost. And, during the process the workers should hold the main body before the device is applied, which makes the workers tired.
SUMMARY OF THE INVENTION
Therefore, it is a first object of the present invention to provide a method of fabricating automotive door trim which can reduce a fabricating cost.
It is a second object of the present invention to provide the method which can release the endeavor of the workers.
It is a third object of the present invention to firmly fix the peripheral edge of the ornamental member into the main body.
To achieve the first and second objects, the present invention provides a method for placing the door main body on a lower die, which has a sensor for detecting the accurate placement of the body.
To achieve the third object, the peripheral edge of the ornamental member is fixed into a slit formed in the door trim main body.
The method according to one embodiment of the present invention is done using a lower die, a first upper die, a second upper die, and a third upper die.
The method according to another embodiment of the present invention uses door trim main body made of plastics.
