Abstract

An airbag device includes an airbag and an inflator disposed at a side of a base portion of the airbag for inflating the airbag. The airbag is inflated such that distal ends thereof extend away from the base side of the airbag. The airbag includes a left half airbag to be inflated at a front left of a vehicle occupant, and a right half airbag to be inflated at a front right of the vehicle occupant. The distal ends of the left half airbag and the right half airbag are spaced part from each other to form an empty space therebetween facing the vehicle occupant when the airbag is inflated.

Claims

a left half airbag to be inflated at a front left of the occupant and having a distal end; and

a right half airbag to be inflated at a front right of the occupant and having a distal end, said distal ends of the left and right half airbags being separated from each other to form a space therebetween facing the occupant when the airbag is inflated.

2. An airbag according to claim 1, wherein said distal ends of the left and right half airbags are spaced by a distance between 150 and 350 mm when the airbag is inflated.

3. An airbag according to claim 1, further comprising a base for communicating the left and right half airbags, said left and right half airbags being inflatable by a common inflator.
