Airbag apparatus for front passenger seat

摘要

An airbag apparatus for a front passenger seat includes a fracture-opening section which is defined in an interior cover and is split into front and rear subsections upon inflation of an airbag, and front and rear reinforcement plate members fixedly attached to back surfaces of the front and rear subsections. Upper bent portions and lower bent portions are alternately formed at predetermined intervals at each of the mutually-opposed end portions of the front and rear reinforcement plate members such that a vertical step is formed between the upper bent portions and the lower bent portions. A projection tongue having an engagement hole is provided at the tip end of each upper bent portion. A projection engageable with the engagement hole is formed on the upper face of each lower bent portion. The mutually-opposed end portions of the front and rear reinforcement plate members are superposed and engaged with each other in such a manner that the projection tongues are located above the lower bent portions.
