Abstract
Abstract An air bag cover and manufacturing method thereof wherein the air bag cover comprises a core member which can be formed by injection molding, and a decorative sheet disposed on the surface of the core member. The decorative sheet includes at least two layers, an outer layer and a barrier layer disposed on a back side of the outer layer to protect the outer layer when the core member is injection molded. The core member is made of thermoplastic elastomer which can be thermally fused to the barrier layer. A breakable portion is provided in the barrier layer and core member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
An air bag cover for covering an air bag comprising: a decorative sheet having a barrier layer and an outer layer disposed on the barrier layer; and a core member thermally fused to the barrier layer of the decorative sheet, wherein the core member and the barrier layer define a recess, the recess providing a breakable portion capable of breaking upon an expansion of the air bag, and wherein the barrier layer is higher in tensile strength than the outer layer.
Claim 2
Dependent Claim
81 words
An air bag cover for covering an air bag comprising: a decorative sheet having a barrier layer and an outer layer disposed on the barrier layer; and a core member thermally fused to the barrier layer of the decorative sheet, wherein the core member and the barrier layer define a recess, the recess providing a breakable portion capable of breaking upon an expansion of the air bag, and wherein the barrier layer is higher in tensile strength than the outer layer.
Claim 3
Dependent Claim
