らない。The gas generating agent used in the gas generating device is an inorganic compound consisting of a metal and nitrogen, such as an azide of an alkali metal or alkaline earth metal, or a metal nitride, and a metal and oxygen that react with this to liberate nitrogen gas. It is a powder composition whose main components are sulfur compounds and inorganic compounds commonly referred to as oxidizing agents, such as metal salts of nitric acid, chloric acid, and perchloric acid. These gas generating agents are instantly ignited in response to the rapid deceleration that occurs during a collision of an automobile, and generate a predetermined amount of nitrogen gas within several tens of milliseconds. Examples of its composition are JP-B No. 53-229411 and JP-B No. 57-29.

A large number of known examples are introduced in No. 122986, Japanese Unexamined Patent Publication No. 1-122987, etc. The design of a practical gas generating composition is required to be extremely reliable, and reliability is guaranteed over a long period of time as it is an automobile safety protection device that will be used for about 10 years or more. It must be Since the gas generating composition is contained in a gas generating chamber in the form of powder, granules, or pellets, the reaction is a heterogeneous reaction, and the reaction rate depends on chemical changes in the composition components and It is significantly dominated by heterogeneity such as the physical form of the powder. Therefore, the gas generant composition must be contained within the gas generation chamber such that its chemical properties and physical shape and state of assembly remain as originally set for a significant period of time.
[発明が解決しようとする課題]

になることを知った。[Problems to be Solved by the Invention] However, gas generating agent compositions generally contain atmospheric oxygen,
When exposed to the influence of water vapor and carbon dioxide, not only its reactivity tends to change chemically, but it also tends to turn into powder under vibration. The present inventors found that a composition formed into uniform granules or pellets is likely to come into contact with adjacent granules or pellets due to vibration and be destroyed from the outer edge, resulting in a mixture of non-uniform sizes and shapes. I learned that this causes variation in reaction speed.
本発明は、こうした状況の下に、ガス発生室に収納され

するものである。Under these circumstances, the present invention aims to ensure that the gas generating composition stored in the gas generating chamber does not change chemically and does not change its shape due to vibration, and therefore maintains various performances at the initial stage of manufacture for a long period of time. It is an object of the present invention to provide a gas generator for a protective bag that can be stably maintained over a long period of time.

I found that this can be solved by.

することもできる。According to the present invention, the chemical components of the gas generating composition do not change in quality, and the shape of the composition does not change, so the nitrogen release reaction rate during operation of the gas generator can be maintained as designed for a long period of time. This eliminates the need to anticipate a decline in performance and compensate for this decline in advance, minimizing the storage volume.In addition, since it is packaged, it is easy to handle, making loading operations more efficient. - can also be converted into

ものでなければならない。In the present invention, the gas generating composition stored in the gas generating chamber must be hermetically packaged in a substantially gas-free state using metal foil, synthetic resin film, laminate film of metal foil and synthetic resin film, etc. No.

)。The gas-generating composition can be prepared by directly applying a vacuum packaging method to the powder or granules and compacting them into a predetermined shape by the compression action of atmospheric pressure (Fig. 4), or by compressing them into a predetermined shape using a known tableting machine. After being compacted, it can be wrapped in the foil or synthetic resin membrane and sealed in a vacuum packaging method (Figure 3).

。Alternatively, each molded element formed by a tablet press may be sealed and packaged (FIG. 2). Metal foil used for sealed packaging,
For the synthetic resin film, a material having a thickness of several μm to several tens of μm is used. By using a material that shrinks due to heat for the synthetic resin film, the compaction effect and shape retention effect can be enhanced. When applying the vacuum packaging method, it is preferable to use a method in which the inside of a bag formed of a membrane material is replaced or filled with nitrogen gas and suctioned with a vacuum pump to apply a heat sealing method.

収納されてもよい。FIG. 1 shows one embodiment of the gas generating device, in which hermetically sealed pellets containing compacted gas generating compositions are stacked and housed in a gas generating chamber. In this example, the ignition device is provided inside the gas generation chamber. The gas generating composition may be a one-piece sealed package that occupies the entire space of the gas generating chamber. In this case, the gas generating composition may be stored in a predetermined amount of powder, granules, or small pellets in a sealed package.

ましくは100Torr以下(室温下)が好適である。Since the composition inside the sealed package with a predetermined shape is under pressure lower than atmospheric pressure, it is constantly tightened by the membrane and foil, increasing the degree of filling, preventing mutual movement, and preventing the shape from collapsing due to vibration and friction. is suppressed. In other words, when the composition of the present invention is gas-free, it means that the gas-generating composition is hermetically packaged under reduced pressure. The degree of pressure reduction is preferably as low as possible, with the upper limit being the degree at which the compaction effect of atmospheric pressure is recognized. Approximately 300 Torr, preferably 100 Torr or less (at room temperature) is suitable.
