Description

Vehicle Luggage Side Trim The present invention relates to a luggage side trim for automobiles, and more specifically, to a luggage side trim manufactured by laminating a non-woven wall paper and a hard cotton felt layer, wherein the hard cotton felt layer is composed of a mixture of recycled cotton felt, PET (Polyethylene terephthalate), and LM (Low Melt Fiber), thereby enabling not only environmentally friendly performance and improved noise reduction but also a simplified manufacturing process. The luggage side trim of a vehicle is an interior panel that covers the left and right sides of the trunk or cargo compartment. It has an aesthetic improvement function that maintains a neat appearance by concealing metal, wires, screws, etc. inside the trunk; a protective function that prevents items loaded in the trunk from hitting the side of the vehicle body and causing damage or scratches; a noise reduction function that absorbs noise inside the trunk to reduce noise while driving; and some side trims have hooks or loops that allow for additional attachment functions, such as securing cargo or installing additional accessories for storage. The following (Patent Document 1) to (Patent Document 3) disclose technology regarding such luggage side trim. (Patent Document 1) Korean Published Patent No. 10-2024-0063256 A method for manufacturing a luggage side trim according to one aspect comprises: an oven heating step in which a fabric laminated with W/paper, PET coating, PET foam, and non-woven fabric is heated in an oven; a foaming step in which PET foam is foam-molded simultaneously with the heating of the oven heating step; a cold pressing step in which the fabric that has undergone the oven heating step is formed into the shape of a luggage side trim using a cold presser; a trimming and piercing step in which a hole is formed or a cutting operation is performed on the fabric that has undergone the cold pressing step; and a bracket assembly step in which a bracket is assembled to the fabric that has undergone the piercing step. A method for manufacturing a luggage side trim may be provided, wherein the luggage side trim is configured to support the left or right wall of a trunk formed at the rear of a vehicle and is formed with a space expansion portion having one side protruding to one side to expand the space of the vehicle trunk, and the opposite side of the space expansion portion is formed as a seat connection portion extending to the rear seat of the vehicle; wherein the space expansion portion is formed by foam molding of at least 60% of the upper area of the space expansion portion during the foaming step, and the seat connection portion is formed by foam molding of at least 60% of the lower area during the foaming step, thereby forming a second sound-absorbing portion. (Patent Document 2) Korean Registered Patent No. 10-1836470 The invention relates to a side trim for a luggage room of a vehicle, comprising a first side trim installed on one side of the luggage room of the vehicle, a second side trim installed on the other side of the luggage room of the vehicle and facing the first side trim, and a fixing member rotatably coupled to the first side trim and detachably coupled to the second side trim and configured to fix luggage accommodated in the luggage room, thereby restricting the forward and backward movement of luggage and, when luggage is not stored, the fixing member is stored inside the side trim, thereby maximizing the space utilization of the luggage room. (Patent Document 3) Korean Published Patent No. 10-2019-0000945 A luggage side trim for an automobile is provided, which allows the luggage side trim to be assembled quickly and conveniently attached to the trunk panel using an interference fit method while reducing the number of parts by mounting a net hook plate on the luggage side trim facing the trunk panel and configuring the luggage side trim so that the net hook plate is inserted into a pin configured on the trunk panel. In particular, the pin mounted on the trunk panel is configured not only to be used to secure the luggage side trim in this manner but also to allow the net hook to be attached after the luggage side trim is mounted, thereby providing a luggage side trim for an automobile that allows the net hook to be easily attached and conveniently used without having a separate means (net hook assembly) for securing the net. [Fig. 1] is a perspective view of the rear of a vehicle with the trunk lid open to show the mounting position of the luggage side trim for a vehicle according to the present invention. [Fig. 2] is a cross-sectional view showing the layer structure of a luggage side trim for an automobile according to the present invention. [Fig. 3] is a photograph showing an example of a luggage side trim for an automobile made of non-woven material, wall paper, and a hard cotton felt layer according to the present invention.
