Skin structure and interior part using the same

Abstract

A skin structure is constituted by laminating a space holding layer 1 and a low lightness layer 2 on a base material 3, laminating the space holding layer 1 on a base material 4 of low lightness, or laminating a space holding layer 5 of low lightness on the base material 3. Accordingly, an increase in surface temperature of an interior material caused by direct solar radiation or solar radiation through glass and reflection in a window can be prevented.

What is claimed is:  
     
         1 . A skin structure, comprising: 
 a base material;    a low lightness layer laminated on the base material, the low lightness layer showing low lightness to incident light; and    a space holding layer laminated on the low lightness layer, the space holding layer forming a space on the low lightness layer.    
     
     
         2 . A skin structure, comprising: 
 a base material; and    a space holding layer laminated on the base material, the space holding layer forming a space on the base material,    wherein the base material is set to have low lightness.    
     
     
         3 . A skin structure, comprising: 
 a base material; and    a space holding layer laminated on the base material, the space holding layer forming a space on the base material,    wherein the space holding layer is set to have low lightness.    
     
     
         4 . The skin structure of  claim 1 , further comprising: 
 a light transmitting layer laminated on the space holding layer, the light transmitting layer allowing the incident light to be transmitted therein.    
     
     
         5 . The skin structure of  claim 4 , 
 wherein a light transmittance of the light transmitting layer ranges from 30% to 98%.    
     
     
         6 . The skin structure of  claim 1 , 
 wherein a thickness of the space holding layer ranges from 0.5 mm to 20 mm.    
     
     
         7 . The skin structure of  claim 1 , 
 wherein a light transmittance of the space holding layer ranges from 5% to 95%.    
     
     
         8 . The skin structure of  claim 1 , 
 wherein a Munsell value of the low lightness layer is 6.0 or below.    
     
     
         9 . The skin structure of  claim 2 , 
 wherein a Munsell value of the base material is 6.0 or below.    
     
     
         10 . The skin structure of  claim 4 , 
 wherein a surface of the light transmitting layer has an anti-reflection function.    
     
     
         11 . The skin structure of  claim 1 , 
 wherein a Munsell value of the space holding layer is 6.0 or below.    
     
     
         12 . The skin structure of  claim 1 , 
 wherein the space holding layer is a fiber.    
     
     
         13 . The skin structure of  claim 1 , 
 wherein the space holding layer is three dimensional fabric.    
     
     
         14 . The skin structure of  claim 4 , 
 wherein the light transmitting layer comprises at least one of resins selected from polyvinyl chloride resin, thermoplastic olefin resin, and polyurethane resin.    
     
     
         15 . The skin structure of  claim 1 , 
 wherein the low lightness layer includes a highly heat conductive material.    
     
     
         16 . The skin structure of  claim 1 , 
 wherein the base material includes a highly heat conductive material.    
     
     
         17 . An interior part, comprising: 
 a skin structure comprising a base material; a low lightness layer laminated on the base material, the low lightness layer showing low lightness to incident light; and a splice holding layer laminated on the low lightness layer, the space holding layer forming a space on the low lightness layer.    
     
     
         18 . The interior part of  claim 17 , 
 wherein the skin structure is applied to at least one of parts selected from an instrument panel, a door trim, a rear parcel shelf, and a pillar garnish of the interior parts.
