A resin composition for a seamless air bag cover or a resin composition for a seamless instrument panel having an air bag cover which comprises (A) 50 to 90% by mass of polypropylene, (B) 0 to 20% by mass of a thermoplastic elastomer and (C) 10 to 30% by mass of talc having an average particle diameter of 15 to 25 &#x3bc;m and a distribution of a particle diameter such that the content of particles having a diameter of 5 &#x3bc;m or smaller is 10% by mass or smaller and the content of particles having a diameter exceeding 40 &#x3bc;m is 10% by mass or smaller. The resin composition exhibits sufficient properties when an instrument panel is molded. A seamless instrument panel having an air bag cover can be obtained as an integrally molded product, which can be treated as a single article in recycling.

Resin composition for seamless air bag covers, and seamless air bag covers or seamless instrument panels with air bag covers, made by using the composition

An inventive vehicle air bag door includes a back-up memberprovided on the bottom side of a panel main bodyThe back-up memberincludes a back-up sectiona plate sectionand a hinge sectionwhich are integrally formed. The hinge section includes: a first curved portionwhose midsection is curved so as to protrude toward a door sectionand a second curved portionwhose midsection is curved so as to protrude away from the door section 17. When the door sectionis opened, the first and second curved portionsandare each extended and then the plate sectionis pivoted around its junction with the second curved portion
