Abstract
Abstract A trim member for use as an interior furnishing in a motor vehicle includes a covering sheet including one surface having an embossed pattern, a first foamed body disposed on the other surface of the covering sheet, with a first component embedded partly in the first foamed body, and a second foamed body disposed on the other surface and/or the first foamed body, with a second component partly embedded in the second foamed body. The covering sheet, the first foamed body, and the second foamed body are integrally formed as a unitary construction. Since the trim member is constructed as an integral unitary assembly, it does not squeak while the motor vehicle is running, and does not have visible steps and joints on its outer surface.

Claim 1
Independent Claim
289 words
A method of manufacturing a trim member for use in a motor vehicle, comprising the steps of: providing a covering sheet for the trim member having a predetermined shape and including a surface having an embossed pattern; forming a first foamed body on said covering sheet wherein a first component is positioned on said covering sheet and embedded partly in said first foamed body, said first component being made of a metallic material, wherein said first foamed body is formed by introducing a first foamable resin into a foaming device having an upper mold die and a lower mold die while said covering sheet is attracted to said lower mold die by a vacuum suction means, said first foamed body having integrally formed therein at least one of the rib and an attachment base for positioning a second component thereon; providing a parting agent of said first foamed body during formation thereof; blasting the parting agent off said first foamed body after the first foamed body is formed; positioning and attaching a second component on at least one of said rib and said attachment base, said second component being made from a resin material; forming a second foamed body on at least one of said covering sheet and said first foamed body by introducing a second foamable resin into said forming device after formation of said first foamed body such that said second component becomes positioned and embedded partly in said second foamed body; and trimming said second foamed body after the second foamed body is formed; wherein said covering sheet comprises a composite sheet material comprising a leather-like resin sheet and a foamed sheet of polyolefin, said resin sheet and said foamed sheet being superposed on each other.
