Airbag device and airbag

摘要

An airbag device has an airbag and an inflator for inflating the airbag. The inflator disposed at a base side of the airbag ejects gas to inflate the airbag such that a distal end of the airbag moves away from the base side of the airbag. The airbag includes a left half airbag to be inflated at a front left side of a vehicle occupant and a right half airbag to be inflated at the front right side of the occupant. Distal ends of the left and right half airbags are separated by a space facing the occupant when the airbag is inflated. Each half airbag has a belt for connecting panels for each half airbag to restrict width thereof. The left and right half airbags have primary folded portions having vertically elongated folded states and secondary folded portions having vertically folded states to form a finally folded state.
