Abstract

An occupant protection apparatus for a vehicle includes a curtain airbag device and a side airbag device. The vehicle includes a side window glass for closing from a vehicle body upper construction to a waist line of the vehicle. The curtain airbag device includes a curtain airbag and is installed at the vehicle body upper construction. The side airbag device includes a side airbag stowed at a lower level than the waist line and installed in a seat of the vehicle. Upon a side impact to the vehicle, the curtain airbag is developed downward, and the side airbag is inserted into a space between the curtain airbag and the side window glass. According to the occupant protection apparatus, development, man-hours such as adjustments of gas amounts of inflators and a production cost can be decreased in spite of the installation of at least two types of airbags.
