In order to manufacture a head rest skin as a final product, a main portion (G) of the skin, which lacks a lower surface portion (K) of the skin, necessary to complete the head rest skin as the final product, is prepared first. Then, a lower surface opening peripheral edge (g) of the main portion (G) of the skin is turned up to expose a back surface of the skin, and a decorated surface (I) of the main portion (G) of the skin is folded into the turned up lower surface opening peripheral edge. A peripheral edge (k) of a lower surface portion (K) of the skin and the lower surface opening peripheral edge (g) of the main portion (G) of the skin are overlapped one upon another in such a manner that the decorated surfaces of these edges (g), (k) confront each other with the back surface (R) of the lower surface portion (K) of the skin facing outward, and the overlapped peripheral edge portions are thereafter joined. Then, the main portion (G) of the skin on the decorated surface side is pulled out by taking advantage of a slit 9 formed in the lower surface portion (K) of the skin so that the skin is arranged right side out.

Method of manufacturing head rest skin

A method for manufacturing an interior member for vehicles comprises the steps of laying a surface layer in a cavity of a mold, placing a reinforcing fiber mat onto the surface layer, compressing the surface layer and the reinforcing fiber mat in the mold, injecting raw material for obtaining a polyisocyanurate and demolding an integrally-molded interior member from the mold after the completion of a reaction of the raw material. The raw material comprises a trimerization catalyst, a polyol and a polyisocyanate. The amount of raw material is determined so that the density of the obtained polyisocyanurate is 1.2 to 1.9 times as much as the density of the same polyisocyanurate in its free foaming state.

Method of manufacturing an interior member for vehicles

An improved interior member for vehicles which includes a substrate containing a reinforcing fiber mat with a polyisocyanurate permeated therethrough and a surface layer integrally formed on the substrate. The amount of the polyisocyanurate is so determined that the density of the polyisocyanurate in said substrate is 1.2 to 1.9 times as much as the density of the same polyisocyanurate in its free foaming state. The surface layer may include a fabric, a resilient foam and a thermoplastic resin sheet in layers, or alternatively may include non-foamed plastic as an outer layer and foamed plastic as an inner layer. A method for manufacturing the above interior member for vehicles is neither complicated nor costly.
