1. An occupant protection device for protecting an occupant in a vehicle, comprising:
- gas generating means for generating gas,an airbag device attached to the gas generating means to be deployed in front of the occupant, said airbag device having a thorax-protection airbag to be deployed in front of a thorax of the occupant and a head-protection airbag to be deployed in front of a head of the occupant above the thorax-protection airbag, anddetecting means for detecting a sitting height of the occupant so that both the head-protection airbag and the thorax-protection airbag are inflated when the detecting means detects a sitting height higher than a predetermined value, and only the thorax-protection airbag is inflated when the detecting means detects a sitting height lower than the predetermined value.

Abstract
An occupant protection device includes an airbag to be deployed in front of a vehicle occupant and a gas generator for inflating the airbag. The airbag includes a thorax-protection airbag to be deployed in front of a thorax of the occupant and a head-protection airbag to be deployed in front of a head of the occupant. Since the occupant protection device includes the thorax-protection airbag and the head-protection airbag, the individual airbag has a small capacity and requires an inflator with an output lower than that in the conventional airbag device.

7. An occupant protection device for protecting an occupant in a vehicle, comprising:
-
gas generating means for generating gas, and an airbag device attached to the gas generating means to be deployed in front of the occupant, said airbag device having a thorax-protection airbag to be deployed in front of a thorax of the occupant and a head-protection airbag to be deployed in front of a head of the occupant above the thorax-protection airbag, said head-protection airbag having a right half bag, a left half bag and a space in a middle between the right and left half bags, said space extending from a lower portion of the head-protection airbag to separate the right and left half bags so that the right and left half airbags are communicated with each other at an upper side of the right and left half airbags above the space, wherein said head-protection airbag further includes a portion for communicating the left half bag and the right half bag above the space, said communicating portion being integrally formed with the left and right half bags. - View Dependent Claims (8, 9, 10)
