Description

Fabric bonding device {Bonding device for material}

The present invention relates to a fabric joining device, and more particularly, to a fabric joining device including an elastic member.

Interior materials for vehicles include door trims, pillars, trunk mats, package trims, and headliners. A door trim refers to a member that covers and covers a locking device, a speaker, a window device, etc. from the inside of a car door. The door trim not only decorates the interior, but also performs the functions of sound insulation, absorption, and shock mitigation.

The door trim may include a plastic part called a base material and a fabric part called a skin material. The fabric part is also responsible for the interior effect, and may be located in a part that is in contact with or exposed to people.

The substrate and the skin material may include different materials. The substrate and the skin material may be bonded after being molded by different methods. Various methods for bonding the substrate and the skin material are being studied.

A manual operation may be required for bonding the end portions of the substrate and the skin material. The manual process can be time consuming and costly. The production cost of the door trim may increase. This manufacturing method can be applied to not only the door trim, but also various other interior materials for vehicles.
