Description

Door Trim Fixing Apparatus The present invention relates to a door trim fixing device, and more specifically, to a door trim fixing device that can solve watertightness problems that may occur during the manufacturing process or vehicle use by being coupled to a door trim without forming a separate hole for coupling in the door panel. Generally, various automotive interior components are installed to ensure the safety of occupants. Door trims are designed to wrap around the door panel while protecting the user from external impacts. Door trims provide functions such as sound insulation and absorption, and also offer conveniences like speakers and storage compartments. The door trim and door panel are joined using fasteners, etc., and the structure is such that a joining groove is formed in the door panel, a fastener leg is inserted into the formed joining groove, and the fastener is fixed in the joining groove when the wing portion of the leg elastically restores. When the fastener is coupled to the groove formed in the door panel, it is secured, but there is a problem where rainwater from the outside enters the interior of the vehicle through the groove of the door panel when the vehicle is in use. To prevent this, watertight pads or fasteners with injection molding are used; however, in such structures, replacing the fastener requires forcibly pulling it out of the connection groove. Forcibly pulling out the fastener causes deformation in the door trim and door panel, resulting in noise.
