Side airbag device
First Claim
1. A side air bag device in combination with an edge of a door opening comprising:
- an air bag; and
an inflator that supplies inflation gas to the air bag,wherein the air bag includes a cloth bag that is installed in a folded state in a vehicle interior along the edge of the door opening so as to cover the door opening upon inflation, the air bag having a tubular gas inflow portion,wherein said tubular gas inflow portion is sealed by being clamped to an outer surface of the inflator.

Abstract
A side air bag device has an air bag and a substantially cylindrical inflator for supplying inflation gas to the air bag. The air bag includes a cloth bag and is installed in a vehicle interior in a folded state along the edge of a door opening. The air bag deploys so as to cover the door opening when it inflates. The air bag has a substantially cylindrical tubular gas inflow portion. This gas inflow portion is connected to the inflator so that it covers the inflator. The gas inflow portion is clamped to the outer circumferential surface of the inflator. With a side air bag device according to the invention it is not necessary to use a long pipe that from the inflator and it is possible to increase the freedom of installation of the device and also reduce its weight and cost.

8. A side air bag device in combination with an edge of a door opening comprising:
-
an air bag; and an inflator that supplies inflation gas to the air bag, wherein the air bag includes a cloth bag that is installed in a folded state in a vehicle interior along the edge of the door opening so as to cover the door opening upon inflation, and wherein the inflator comprises an inflator housing that includes a gas delivery opening in a circumferential face thereof and a tubular diffuser that includes; at one end thereof a mating portion that mates with the inflator housing, at another end thereof a gas emission opening that emits inflation gas, and an intermediate portion disposed between the mating portion and the gas emission opening so as to face the gas delivery opening, wherein the mating portion of the diffuser includes a female screw thread on an inner surface of the diffuser, the inflator housing includes a male screw thread on an outer surface thereof, the male screw thread being matable with the female screw thread, and the diffuser is fixed to the inflator housing by mating the male and female screw threads and wherein the intermediate portion of the diffuser provides a gas flow path between the outer circumferential surface of the inflator housing and the intermediate portion, in an area from the gas delivery opening to the gas emission opening, such that inflation gas flowing from the gas emission opening flows substantially uniformly around the inflator housing. - View Dependent Claims (9, 10)
