Automotive crash pad and manufacturing method thereof

Abstract

An automotive crash pad and a method for manufacturing the same. The automotive crash pad includes: a skin layer forming the outer surface of the crash pad including an airbag module; a fiber-based layer formed on the lower surface of the skin layer; a cushion layer formed on the lower surface of the fiber-based layer and including slab foam; and a core layer formed on the lower surface of the cushion layer, wherein a laminate of the skin layer and the fiber-based layer has a tensile strength in transverse direction (TD) of 5 to 50 kgf / 3 cm and an elongation at break in transverse direction (TD) of 40 to 220%.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from and the benefit of Korean Patent Application No.10-2020-0090302, filed on Jul. 21, 2020, which is hereby incorporated by reference for all purposes as if set forth herein.BACKGROUNDField[0002]Exemplary embodiments of the present disclosure relate to an automotive crash pad and a manufacturing method thereof.Discussion of the Background[0003]A crash pad, also called an instrument panel, is an automotive interior part that is attached to the lower end of the front glass of the driver's seat. An airbag is mounted in the crash pad. The airbag functions to protect the occupant's life from an external shock by deployment through the seam line of the crash pad when a crash occurs. Thus, the airbag is a very important part in terms of design, convenience and stability.[0004]FIG. 1 illustrates a conventional automotive crash pad, and FIG. 2 illustrates a conventional crash pad. Referring to FIGS. 1 and 2, a cra...

AI Technical Summary

Benefits of technology

The present invention provides an automotive crash pad with excellent airbag deployment performance, economic efficiency, sensitivity properties, and adhesion between the skin layer and foam layer. The pad can quickly deploy airbags in the event of an external shock, even without a skin layer-weakening process. The pad has a good tear shape, is easy to manufacture, and has soft tactile sensation.

Problems solved by technology

However, natural leather has problems in that it is expensive and the quality control thereof is difficult, so that deformation or surface damage of the natural leather easily occurs.

However, when the crash pad is manufactured by performing the skin layer-weakening process, problems arise in that material and process costs increase, resulting in decreases in productivity and economic efficiency, and the labor cost and work time associated with the skin layer-weakening process are added.
