Abstract
Official abstract text for this publication.
Provided is a soft upper trim of a vehicle door, in which an upper substrate, a foam, and a transparent skin are laminated, and particularly, to a soft upper trim for switch assembly of a vehicle door, in which a switch, which is configured to preserve continuity of a transparent skin and display lock and unlock symbols on the transparent skin, is easily assembled to an upper substrate, and a method of manufacturing the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a soft upper trim for a switch assembly of a vehicle door, the method comprising: (a) double injection-molding an upper substrate and a light guide plate on a lower surface of a foam-molded foam in an inserted state such that an upper surface of the upper substrate, into which a switch module is inserted, is placed on a same line as an upper surface of the light guide plate; (b) forming a hole in the foam-molded foam up to a position where the light guide plate is placed; (c) vacuum-pressing a preheated transparent skin on the foam-molded foam in an in-mold grain mold; and (d) engraving a symbol in a rear surface of the light guide plate at a position corresponding to the hole. 2. A soft upper trim for a switch assembly of a vehicle door, the soft upper trim comprising: an upper substrate, a foam, and a transparent skin which have been laminated wherein; a recessed groove formed in the upper substrate, a switch module being inserted into the recessed groove; a light guide plate injection-molded above the recessed groove, the light guide plate being placed on a same line as an upper surface of the upper substrate; and a symbol engraved in a rear surface of the light guide plate. 3. The soft upper trim according to claim 2 , wherein the light guide plate includes: side plates; an upper plate connecting upper surfaces of the side plates and having the symbol engraved therein; flanges formed at lower ends of the side plates; and an accommodation groove formed inside a lower side of the light guide plate, an upper side of the switch module being inserted and accommodated in the accommodation groove.
