A side airbag device for a vehicle has a simple structure which allows a high-pressure chamber of a side airbag to be promptly inflated and expanded and allows the pressure in the high-pressure chamber to be maintained for a long time. A side airbag (16) has a high-pressure chamber (28) and a low-pressure chamber (30) the inner pressure of which becomes a pressure lower than the pressure in the high-pressure chamber (28). An inflator (22) is provided in the low-pressure chamber (30) with a gas discharge section (22A) facing the high-pressure chamber (28). In a side collision, gas from the inflator (22) is supplied mainly toward the high-pressure chamber (28) and is supplied also to the low-pressure chamber (30). The high-pressure chamber (28) and the low-pressure chamber (30) are partitioned by a partition wall (18). A check valve (24) mounted to the partition wall (18) is opened by the pressure of the gas supplied from the inflator (22), which is provided in the low-pressure chamber (30), toward the high-pressure chamber (28), and thus the check valve (24) permits the gas to flow from the low-pressure chamber (30) to the high-pressure chamber (28). When the inflator (22) completes the discharge of the gas, the gas tries to flow back from the high-pressure chamber (28) to the low-pressure chamber (30), but the check valve (24) restricts such flow of the gas.

The present invention provides a hybrid gas generator which is capable of keeping an air bag inflated by generating a lower-temperature gas so that the internal pressure of the air bag is maintained following inflation of the air bag.

A shutoff valve mechanism for a plastic injection molding system and process. The shutoff valve mechanism is positioned between the nozzle of the injection molding machine and the hot runner manifold. Force applied by the machine nozzle moves an inner body member in the shutoff valve mechanism and opens a valve allowing molten plastic material to flow through the valve and into the hot runner, sprue bushings, and mold cavities. A biasing mechanism, such as a plurality of spring washer members, returns the inner body member to its rest position, thereby closing the valve mechanism when the machine nozzle is retracted.
