First Claim
1. An occupant protection device for a vehicle having a longitudinally front seat, middle seat and rear seat in a passenger compartment, comprising:
- an inflator for generating gas; and
a roof side airbag placed in a certain pillar space which is formed by a pillar garnish mounted to a passenger compartment side of a front pillar provided at a front part of a vehicle body, and in a longitudinally elongated certain roof space provided at a side corner of a roof on the passenger compartment side, to be inflated by the gas along side glasses toward the passenger compartment;
wherein the roof side airbag comprises;
gas inlets disposed in a longitudinally substantially middle portion to receive gas supply from the inflator;
gas main passages extending longitudinally from the gas inlets along the roof space;
a front bag portion to be inflated in a position corresponding to the front seat;
a middle bag portion to be inflated in a position corresponding to the middle seat;
a rear bag portion to be inflated in a position corresponding to the rear seat; and
inner tubes placed in the gas main passages for distributing the gas to the bag portions,wherein the inner tubes include position stabilizing members longitudinally fitted in the inner tubes to maintain the shape of the inner tubes and prevent the fluttering of the inner tubes during the pulsating flow of the gas into the inner tubes,wherein the gas main passages communicate with the bag portions, andwherein the front bag portion includes an inflating portion in which, during inflation toward the passenger compartment along the side glasses, gas flowing in from the communicating gas main passage heads downward and then flows forward and upward.

Abstract
An occupant protection device for a vehicle having several longitudinal rows of seats in a passenger compartment. The occupant protection device includes an inflator for generating gas and a longitudinally elongated roof side airbag mounted to a roof side rail. The roof side airbag includes a plurality of bag portions to inflate in positions corresponding to the rows of seats, respectively. Gas generated from the inflator flows through gas inlets disposed in a substantially middle portion of the roof side airbag into the bag portions generally uniformly, and the roof side airbag inflates along the inside of side glasses of the vehicle.
