Abstract

A skin covered foamed plastic article capable of providing improved softness, feel and comfortableness by reducing the amount of penetration of the liquid foam resin into the skin cover with a thin wadding. The article includes a wadding to be attached on a back side of the surface skin and to make a direct contact with the pad member, having a soft layer contacting the surface skin and a hard layer contacting the pad member which has a constant thickness and is made to be harder than both the soft layer and the pad member.

Claims

1. A skin covered foamed plastic article, comprising:

a pad member; and

a skin cover covering the pad member, including;

a surface skin forming an outer surface of the skin covered foamed plastic article; and

a wadding attached on a back side of the surface skin, making a direct contact with the pad member, and having a soft layer contacting the surface skin and a hard layer contacting the pad member which has a constant thickness and which is harder than both the soft layer and the pad member.

2. The skin covered foamed plastic article of claim 1, wherein the hard layer is harder than both the soft layer and the pad member by a uniform penetration into the hard layer of liquid foam resin which stiffens in a foaming process.

3. The skin covered foamed plastic article of claim 1, wherein a thickness of the hard layer is in a range of 1 to 5 mm.

4. The skin covered foamed plastic article of claim 1, wherein the wadding has an air permeability of not greater than 120 cc/cm² /sec, and a cell number of 40 to 50/25 mm.

5. The skin covered foamed plastic article of claim 1, wherein the surface skin and the wadding of the skin cover are flame laminated with a surface of the wadding facing the surface skin being melted for not less than 0.3 mm and less than 0.8 mm thickness.

6. The skin covered foamed plastic article of claim 5, wherein the surface skin and the wadding of the skin cover are flame laminated with a surface of the wadding facing the surface skin being melted for 0.5 mm thickness.

7. A skin covered foamed plastic article, comprising:

a pad member; and

a skin cover covering the pad member, including;

a surface skin forming an outer surface of the skin covered foamed plastic article; and

a wadding attached on a back side of the surface skin, making a direct contact with the pad member, and having an air permeability of not greater than 120 cc/cm² /sec, a density of 20 to 35 kg/m³, and a cell number of 40 to 50/25 mm.

8. A skin covered foamed plastic article, comprising:

a pad member; and

a skin cover covering the pad member, including;

a surface skin forming an outer surface of the skin covered foamed plastic article; and

a wadding attached on a back side of the surface skin, making a direct contact with the pad member, and flame laminated to the surface skin, wherein the surface of the wadding facing the surface skin is melted to a depth not less than 0.3 mm and less than 0.8 mm.

9. The skin covered foamed plastic article of claim 8, wherein the surface skin and the wadding of the skin cover are flame laminated with a surface of the wadding facing the surface skin being melted for 0.5 mm thickness.
