Side-collision airbag apparatus
First Claim
1. A side-collision airbag apparatus, comprising:
- an airbag comprising a first bag portion and a second bag portion adjacent to the first bag portion, the first and second bag portions formed by connecting two base cloths coated with silicon, the second bag portion having a vent hole, the airbag being stored in a folded state in the interior of a seatback portion of a vehicle seat, the airbag configured to be deployed to a side of an occupant on the seat by a supply of gas, the deployed airbag receiving a lumbar part of the occupant at the first bag portion and receiving a chest part of the occupant at the second bag portion;
a cylindrical inflator extending across the first bag portion and the second bag portion at a position between the airbag and the rear of the vehicle, the inflator including a gas injecting portion located in the first bag portion at a distal end of the inflator;
a cylindrical gas distributing member having a gas discharge port that opens into the first bag portion at a distal end of the gas distributing member and a gas passage that opens into the second bag portion and is formed between the gas distributing member and a peripheral surface of the inflator, the gas distributing member being fitted to the peripheral surface and configured to distribute and supply the gas injected from the inflator to the first bag portion and the second bag portion so the flow rate of the gas is higher in the first bag portion than in the second bag portion; and
a communicating portion for communicating gas between the first bag portion and the second bag portion.

Abstract
An apparatus includes an airbag having first and second portions formed by seaming silicon coated cloths where the second portion has a vent. The airbag is folded in a seatback, deploys to a side of an occupant by a gas supply, and receives an occupant lumbar at the first portion and a chest at the second portion. An inflator extends across the first and second portions towards a rear of the vehicle and includes a gas injector in the first portion. A gas distributing member has a discharge port opening into the first portion and a passage opening into the second portion between the distributing member and a surface of the inflator. The distributing member is fitted to the surface and distributes gas from the inflator to the airbag so the flow rate is higher in the first portion. A communicating portion transfers gas between the first and second portions.

6. A side airbag module comprising:
-
an airbag formed from coated fabric and including connected and fluidly communicating first and second portions; and a cylindrical inflator for providing gas to inflate an airbag; wherein prior to inflation the airbag is stored in a folded state in the interior of a seatback portion of a vehicle seat, and wherein the airbag is configured to be inflated and deploy to a position alongside an occupant of the seat so that the first portion of the airbag receives a lumbar part of the occupant and the second portion of the airbag receives a chest part of the occupant; wherein the second portion includes a vent hole, and wherein the inflator extends across both the first and second portions of the airbag, the inflator including a gas injecting portion located in the first bag portion at a distal end of the inflator; a cylindrical gas distributing member having a gas discharge port that opens into the first portion at a distal end of the gas distributing member and a gas passage that opens into the second portion and is formed between the gas distributing member and a peripheral surface of the inflator, wherein the gas distributing member is fitted to the peripheral surface and configured to distribute and supply gas to the first and second portions so that the flow rate of gas from the inflator into the first portion is higher than the flow rate of gas from the inflator into the second portion. - View Dependent Claims (7, 8)
