AIR BAG DEVICE FOR AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To improve a mounting structure arranged at a back surface side of a break opening part of an air bag device.

SOLUTION: The air bag device for an automobile is provided with an air bag case 44 for storing the air bag 43 expanded/deployed by a gas from an inflator in the folding state; the break opening part 46 for defining an opening shape for deployment of the air bag to a back surface of an interior panel opposed to the opening of the air bag case; a reinforcement plate material 47 for reinforcing the break opening part 46; and a frame body 45 closely adhered to a back surface at a peripheral area of the break opening part. The frame body 45 and the reinforcement plate material 47 are formed by thermoplastic resin material respectively and the reinforcement plate material 47 is arranged slidably against the frame body 45. A heat adhesion prevention means 50 is between the respective corresponding surfaces so that the adhesion by joining of the respective corresponding surfaces each other is prevented.
