Description of the invention (1) [Application fields in industry] (Please read the precautions on the back before filling out this page) The present invention is related to gas generators, especially for side impacts or assistants suitable for expansion and expansion. Gas generator for seat airbag. [· Advanced Technology] Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs As an example of the gas generator used to expand and deploy the airbag for side impact, as shown in Figure 5. The gas generator in Fig. 5 has a long cylindrical casing 51 which is closed at both ends. Inside the casing 51, a ring-shaped partitioning accessory 5 2 is fitted. The ring-shaped partition fitting 5 2 is embedded in the inner periphery of the casing 1 and partitions the inside of the casing 5 1 into a combustion chamber 5 3 and a cooling filter chamber 54. An annular groove 56 is formed on the outer periphery of the annular partition member 5 2 for inserting into the annular protrusion 55 of the casing 51. The ring-shaped protrusion 5 5 is formed by applying an extension process to the outer periphery of the casing 51 to protrude into the ring-shaped groove 56. The ring-shaped protrusion 5 5 is fitted in the shape of the ring-shaped groove 5 6, so that the ring-shaped partition fitting 5 2 is positioned and fixed in the casing 51. The combustion chamber 5 3 contains a gas generating agent 57 which generates high-temperature gas by combustion. In the cooling filter chamber 5 4, a cylindrical filter fitting 5 8 is assembled. Furthermore, an ignition means 59 is provided at the end of the shaft of the casing 51 to ignite the gas generating agent 57 in the combustion chamber 53. When this gas generator receives a collision detection signal from the collision sensor, the ignition means 59 is energized and ignited ', and the flame is injected into the combustion chamber 53. In the combustion chamber 5 3, the gas generating agent 5 7 is then ignited by the injected flame, and a large amount of high-temperature gas is generated. The high-temperature gas generated in the combustion chamber 5 3 blows the cracking plate 60 at a predetermined internal pressure and passes this paper standard to apply Chinese National Standard (CNS) A4 specification (210X297 mm)-4-495453 Intellectual Property Bureau, Ministry of Economic Affairs Printed by employee consumer cooperative A7 B7_V. Description of the invention (2) The ring-shaped partition fitting 5 2 flows to the filter fitting 5 8 within the week. Then, the high-temperature gas flows into the filter fitting 58, and after the slag is captured and cooled, the gas discharge holes 5 1 a from the casing 51 are discharged into the airbag. The airbag itself expands and expands with a large amount of net gas discharged from each of the gas discharge holes 51a. [Problems to be Solved by the Invention] Every conventional gas generator uses a ring-shaped protrusion 5 5 of a casing 5 1 to be embedded in a ring-shaped groove 5 2 of a ring-shaped partition fitting 5 2, and the ring-shaped The partitioning fitting 5 2 is positioned for the builder securely housed in the housing 51. Therefore, in order to form the annular groove 56, it is necessary to thicken the axial dimension of the annular partition fitting 5 2 toward the casing 51. Therefore, it is necessary to lengthen the axial dimension of the 'housing 5 1' side in order to be able to assemble the ring-shaped partition fitting 5 2, but in the end, the overall gas generator will be enlarged. In addition, the thickening of the ring-shaped partition fitting 5 2 and the lengthening of the casing 51 1 all aggravate the gas generator and it is difficult to reduce the manufacturing cost. Here, in the technical field of gas generators, the demand for light, inexpensive, and small gas generators is growing. From this perspective, it can be seen that the conventional gas generators are difficult to meet the needs of light weight, low price and small size.

Invention Description (3) Airbags for blown and expanded side impacts or assistant airbags are mainly used for long cylinders The inside of the shell is divided into a combustion chamber and a cooling filter chamber by a partition plate. The combustion chamber is equipped with a gas generating agent that can generate high-temperature gas by combustion, and a filter accessory can be installed in the cooling filter chamber to capture and cool the slag of the high-temperature gas. The shaft end portion of the casing is assembled by an ignition means that enables the gas generating agent in the combustion chamber to ignite and burn from the shaft end side of the casing. Moreover, the gas generator of the present invention is formed with protrusions in such a manner that the casing projects toward the combustion chamber. This protrusion is the one pushing the partition plate body from the combustion chamber side and holding the partition plate body together with the filter fitting. The protrusion is preferably formed by subjecting the outer periphery of the casing to an extension process. Also, although it is necessary to be able to hold the filter accessories, the protrusions can be provided in one place, but ideally, the protrusions can be provided in two places. Moreover, it is more desirable to use a ring-shaped protrusion that protrudes over the entire periphery of the housing. Based on this, the partition plate is held between the protrusion 'ideally the ring-shaped protrusion and the filter accessory, and is positioned and fixed in the housing' Therefore, the thickness of the partition plate can be set to a minimum. That is, the partition plate can be made to have a minimum thickness sufficient to withstand the internal pressure generated by the combustion of the combustion chamber and the heat of the high-temperature gas. Also, when assembling the gas generator, a protrusion is first formed on the housing, and ideally, a ring-shaped protrusion is preferably formed, and the partition plate body is embedded in the inner periphery of the housing, and is connected with the protrusion, ideally a ring-shaped protrusion, to block Of it.

Therefore, the thickness dimension t of the partition plate 2 may be the minimum that can withstand the prescribed internal pressure of the combustion chamber 16 and the heat of the high-temperature gas. As a result, the gas generator S is not limited to the thickness of the partition plate 2 and even the axial length of the housing 1 can be shortened, making it possible to provide lightweight, inexpensive, and compact products. In addition, by mounting the gas generating agent S into the combustion holes 2 3 of the filter fitting 3, the installation volume of the gas generating agent 5 can be ensured in the filter fitting 3, and the length of the casing 1 in the axial direction can be shortened. In addition, by using the separator plate accessory 2, the outer cylinder support accessory 1 3, and the paper size, the Chinese National Standard (CNS) A4 specification (210X297 mm) is applicable. -12-(Please read the precautions on the back before filling in this Page) 495453 A7 B7_ V.
