Abstract
A passenger leg protection apparatus includes an airbag to be inflated at a position in front of legs of a passenger for protecting the legs, a case accommodating the folded airbag, and a gas generating unit for inflating the airbag. The folded body of the airbag includes a wound body folded along lateral folding lines extending laterally relative to the passenger several times in the same folding direction. The airbag is disposed in the case so that the wound body is deployed upward or downward while rolling along a front surface of the legs so as to be unwound when being inflated.
