Description of the invention (i) [Application fields in the industry] I-(Please read the precautions on the back before filling out this page) The invention is suitable for airbags suitable for side impact or assistant seat Expansion and expansion of the gas generator. [Advanced Technology] As an example of a gas generator that expands and deploys an airbag for a side collision, it is as shown in Fig. 7. The gas generator in Figure 7 is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, which is mainly used for expansion and deployment of side impact airbags. It is equipped with a long cylindrical outer fitting 5 2 with one end open, and The housing 5 1 formed by closing the outer cylinder fitting 5 2 and the lid fitting 5 3 on the open side. The outer shell 51 is inserted with a cover fitting 5 3 of the inner cylinder shoulder 5 2 a of the outer cylinder fitting 5 2, and the outer cylinder fitting 5 2 is opened toward the inside by bending the lid 5 2 b. The fitting 5 3 is positioned on the open side inside the outer cylinder fitting 5 2. Further, a ring groove 5 3 a is formed on the cover fitting 5 3 so as to open around the inner periphery of the outer tube 5 2, and a seal ring 54 is installed in the ring groove 5 3 a. When the open end 5 2 b of the outer cylinder fitting 5 2 is bent, the sealing ring 54 is elastically connected with the inner periphery of the outer cylinder fitting 5 2 and the annular groove 5 3 a to seal the inside of the outer shell 51. Inside the casing 51, a partitioning ring 55 is formed along the axis of the casing 51 to form a combustion chamber 56 and a cooling filter chamber 57. In the combustion chamber 56, a gas generating agent 5 8 for burning and generating a high-temperature gas is installed, and in the cooling filter chamber 57, a filter is installed for cooling the high-temperature gas generated by the combustion of the gas generating agent 58. Of cylindrical filter accessories 5 9. Moreover, 'at the bottom 5 2 c of the outer cylinder fitting 5 2, a paper size for spraying i inside the combustion chamber 5 2 is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) _' " S6436 A7 B7 5 2. Description of the invention (2) Flame igniter 60. (Please read the precautions on the back and fill in this page first.) With the gas generator, the igniter 60 is energized and ignited according to the impact signal from the impact sensor. 'The flame is injected into the combustion chamber 5 6' to make the gas. The generating agent 5 8 is on fire and burns, and generates a large amount of high-temperature gas.

After passing through the cooling and trapping slag, it is removed from the casing 5 1 Each of the gas exhaust holes 5 1 a is discharged into the airbag. On the other hand, the airbag is rapidly expanded and expanded by a large amount of clean gas discharged from each gas exhaust hole 51a. [Problems to be Solved by the Invention] However, in recent years, in the technical field of gas generators, in addition to small size and light weight, demand for inexpensive gas generators has been increasing. From this point of view, since the conventional gas generator locates the cap fitting 5 3 on the opening side of the outer cylinder fitting 5 2, it is necessary to separately process the inner cylinder shoulder 5 2 a in the outer cylinder fitting 5 2, resulting in It is difficult to reduce manufacturing costs. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Processing the inner peripheral shoulder 5 2 a will reduce the thickness of the outer tube fitting 5 2 and make it a weaker structure. Therefore, if a structure capable of withstanding the high-temperature and high-pressure gas generated in the casing 51 due to the combustion of the gas generating agent 58 is required, it is necessary to increase the thickness of the entire outer tube fitting 5 2 to compensate for the inner shoulder resistance. The size of the 5 2 a component. As a result, the conventional gas generator needs to process the inner peripheral shoulder 5 2 a. Therefore, its manufacturing cost is increased, and the outer cylinder accessories 5 2 must comply with the Chinese National Standard (CNS) A4 specification. (210 X 297 mm) q S6436 A7 B7 V. Description of the invention (3) The thickness of the body is thickened to make up the size of the inner peripheral shoulder 5 2 a. Therefore, it is difficult to achieve a small and lightweight seeker. [Means to Solve the Problems] In view of the foregoing circumstances, the present invention aims to provide a gas generator that can be made compact, lightweight, and inexpensive. The gas generator related to the present invention (item 1 of the scope of patent application) is a long cylindrical outer cylinder fitting with at least one end open, and a cover fitted in the outer cylinder fitting to lock the opening side of the outer cylinder fitting. The accessories constitute the casing. In the outer cylinder fittings, a gas generating agent that generates high-temperature gas through combustion is installed, and a filter fitting for cooling and trapping slag for processing the high-temperature gas is arranged. One or more ignition means is installed on the casing for the gas generator in the outer cylinder fitting to burn. In the gas generator according to the present invention, an annular groove is formed in the cover fitting and opens toward the inner periphery of the outer cylinder fitting, and an elastic sealing ring is installed in the annular groove. Then, it is made that the opening side of the outer cylinder fitting protrudes into the annular groove to form an annular protrusion, and the annular protrusion is inserted along the shape of the annular groove while being elastically connected to the annular groove. Equipment structure. Thereby, the annular protrusion, that is, the elastic ring is elastically connected with the annular groove of the cover fitting, and the inside of the outer cylinder fitting is sealed and closed from the outside. Further, the ring-shaped protrusions "fit the elastic sealing ring to the ring-shaped groove while being fitted" along the shape of the ring-shaped groove and block it from the inside of the ring-shaped groove. Therefore, the 'cover fitting' is connected by the annular groove and the annular protrusion, and its movement in the outer cylinder fitting is restricted, and it is positioned on the opening side of the outer cylinder fitting.

Therefore, in order to position the cap fitting on the opening side of the outer cylinder fitting, the inner periphery of the outer cylinder fitting is processed as a shoulder blocking portion, and the necessity of thickening the outer cylinder fitting along with the processing of the shoulder blocking portion is eliminated. In addition, by appropriately selecting the protruding amount of the annular protrusion, the shape of the annular groove, and the thickness of the outer cylinder fitting, in addition to the sealing and locking of the outer cylinder fitting and the positioning of the cap fitting, it can prevent gas from being received. The high temperature and high pressure gas generated by the combustion of the generator cause the cap fitting to come out of the outer cylinder fitting. In the gas generator related to the present invention (item 2 of the scope of patent application), those in the scope of the first scope of patent application have a ring-shaped protrusion, which is protruded by applying an extension process around the outer periphery of the outer cylinder fitting Formed in a circular groove. Thereby, the simple process of applying so-called extension processing around the outer periphery of the outer cylinder fitting can complete the sealing and locking of the outer cylinder fitting and the positioning of the cap fitting. In the gas generator (item 3 of the scope of patent application) related to the present invention, the one in the scope of the scope of patent application 1 or 2 is formed as a V around the inner periphery of the outer cylinder fitting. Word shape. Accordingly, when the annular protrusion is formed, that is, without subjecting the lid member to an excessive load, the annular protrusion conforms to the V-shape of the annular groove.

In addition, the protruding amount ί of the annular protrusion 18 is determined based on the relationship between the inclination angle β of the annular groove 16 and the ratio of the thickness d of the outer tube fitting 2 to the depth h of the annular groove 16. The sealing and locking of the opening side 5 of the outer cylinder fitting 2 and the positioning of the cap fitting 3 must be achieved without causing the cap fitting 3 to fall off from the outer cylinder fitting 2 due to the high temperature and high pressure gas generated in the casing 1. strength.

Moreover, the inclination angle β of the annular groove 16, the ratio h / d between the depth h of the annular groove 16 and the thickness d of the outer tube fitting 2 and the annular protrusion. The protruding amount of 18 is determined on the premise that it can be sealed, locked, positioned, and prevented from falling off. (1) The inclination angle Θ of the annular groove 16 is preferably set within a range of 0 = 4 ° to 50 °. In terms of the inclination angle Θ, if the inclination angle is too large, a sufficient locking force between the annular protrusions 18 and the annular grooves 16 will not be obtained. -11-This paper size applies the Chinese National Standard (CNS ) 8 4 specifications (21 × χ297 mm) 4S6436 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy ____ V. Description of the invention (9) Conversely, if a small inclination angle is taken, the outer circumference of the outer tube fitting 9 When the extension processing is performed, the cover parts 3, 4 and the like cause excessive load and cause distortion and other disadvantages. Based on this point of view, the inclination angle 0 is set to a value where θ = 40 to 50 ° where sufficient locking force is obtained without causing distortion. In addition, in the inclination angle Θ, although it is not necessary to make the inclination angle Θ a on the push-out shape 16 a side and the inclination angle 0 b on the push-out shape 16 b side the same, it is necessary to prevent each cover In order to make the fittings 3 and 4 fall out of the fitting 2 of the outer cylinder, it is particularly desirable to set the tilting angle 0 b = 4 0 to 50 °. In addition, when the outer cylinder fitting 2 is subjected to extension processing, in order to enable the force of the extension processing to be uniformly applied to each of the cover members 3, 4, it is desirable to make the inclination angles 0a and 0b approximately the same. (2) The ratio between the depth h of the annular groove 16 and the thickness d of the outer tube fitting 2 is preferably h / d = 2 or less. In addition, if the ratio h / d is too large, the depth h of the annular groove 16 will be too deep, which will cause the strength of each cover fitting 3, 4 to decrease, so it should be set to less than 2. As for the ratio h / d, as long as the locking force between the annular protrusion 18 and the annular groove 16 can be obtained, although it can be appropriately selected, it is more preferably set to 1 or more. (3) The amount of protrusion f of the ring-shaped protrusion 18 is preferably set to 0.7 to 1 · 0 0 X d. As for the protrusion amount, if it is set to be in the range of 0.70 to 1.00xd ^, there may be a fear that a sufficient locking force cannot be obtained between the annular protrusion 18 and the annular groove 16. , And above this range, there is a concern that the strength of caulking obtained by borrowing the ring n dog @ 起 Γ 8 is reduced.

Therefore, the caulking means 7, that is, by using the annular groove 16 and the pushing shape 1 6 a, 1 along the annular groove 16 6 b Inserted ring-shaped protrusion 1 8 The combined force of the two sides makes the elastic sealing ring 17 elastically deform, and at the same time seals and locks between the opening side 5 of the outer cylinder fitting 2 and the cover fitting 3, 尙 locates the cover fitting 3 5 places on the opening side of the outer cylinder fitting 2 and prevent it from falling off [see Figure 3 (c)]. As shown in Fig. 4, the "chin stitching means 8" is also R-phase with the chisel stitching means 7, and is composed of a ring groove 16, an elastic sealing ring 17 and a ring protrusion 18. Moreover, in the caulking means 8, both the annular groove 16 and the annular protrusions 18 fitted along the respective pushing shapes 16a and 16b of the annular groove 16 are fitted. The combined force causes the elastic sealing ring 17 to be elastically deformed. At the same time, the opening and closing side 6 of the outer cylinder fitting 2 and the cover fitting 4 are sealed and locked, and the cap fitting 4 is positioned at the 6 opening sides of the outer cylinder fitting 2.

In the filter fitting 9, a third combustion chamber 12 is formed, which penetrates in the axial direction of the casing 1, and passes through the third combustion chamber 12 to communicate with the first and second combustion chambers 10, 11. The cross fitting 9 is inexpensively manufactured from an aggregate of a knitted metal net, a flat woven metal net, and a bent woven metal wire. In addition, the filter fitting 9 may be produced by winding a metal mesh a plurality of times. In addition, the filter accessory 9 is supported by the filter accessory support 21, and is positioned by an extension process applied around the outer periphery of the outer cylinder accessory 2. The filter accessory support 21 is composed of an inner tube fitting 2 2 inserted into the outer periphery of the filter accessory 9 and partition caps 2 3, 2 4 fitted on the outer shaft end sides of the inner tube fitting 2 2. . A plurality of gas passage holes 22a are formed in the inner cylinder fitting 22. The partition caps 23 and 24 are inserted into the inner periphery of the outer tube fitting 2, and a ring-shaped gas passage space P 2 is formed between the inner tube fitting 2 2 and the outer tube fitting 2. Openings 2 3 A, 2 4 A are formed in each of the partition caps 2 3, 2 4 for communicating the first and second combustion chambers 10, 11 and the third combustion chamber 12. Therefore, the filter accessory support body 2 1 restricts the radial movement of the filter accessory 9 toward the casing 1 by inserting the partition caps 2 3, 2 4 into the inner periphery of the outer tube accessory 2. Also, the filter accessory support 2 1 is used to block each shaft end of the filter accessory 2 by means of the partition caps 2 3, 2 4 to separate the high-temperature gas generated in each combustion chamber 10, 11 from each of the partitions. The openings 2 3 A, 2 4 A of the caps 2 3, 2 4 are guided into the third combustion chamber 12 to limit the high-temperature gas from the shaft ends of the filter fitting 9 'directly', or into the gas passage space P 2 Outflow.

In addition, the gas generating agent 1 3 and the buffer parts 3 1 and 3 2 are prevented from being powdered by vibration. The buffer fitting 3 1 is installed between the gas generating agent 13 in the first combustion chamber 10 and the buffer fitting fixing fitting 3 3 in the cover fitting 4. A cross-shaped slit is formed on the buffering accessory 31 so that the flame power of the self-ignition means 34 can be transmitted to the gas generating agent 13 without error. Further, a buffer fitting 32 is installed between the gas generating agent 13 and the cover fitting 32 in the second combustion chamber 11. The cushioning accessories 3 1 and 3 2 can be formed by using elastic materials such as silicone rubber and silicone sponge rubber body. The ignition means 34 is constituted only by an igniter which can be energized and ignited, and is mounted on the cover fitting 4 from the inside of the casing 1.

Description of the invention (13) The collision of the device detected the signal and was energized and ignited. 1 The gas generating agent 1 3 in the combustion chamber 3 is on fire. [Action and Effect of the Invention] Next, the operation of the gas generator S will be described as follows. When the collision sensor detects the collision of the car, the gas generator S ignites with the flame of the ignition means 34, and the flame of the ignition means 34 bursts the buffer fitting 31, and after opening, it faces the first combustion chamber 10 The interior sprays out and burns the gas generating agent 13 to generate a high-temperature gas. The high-temperature gas generated in the first combustion chamber 10 is introduced into the third combustion chamber 12 by the function of the partition cap 23, so that the gas does not directly flow into the space P 2 and the like, and then flows into the filter fitting 9 After cooling and trapping the slag, the gas flows out into the space P 2. At this time, the third combustion chamber 12 receives heat of the high-temperature gas flowing from the first combustion chamber 10, etc., and causes the gas generating agent 13 to ignite and generate high-temperature gas. Therefore, the combustion in the third combustion chamber 12 is to sequentially burn the gas generating agent 13 from the first combustion chamber 10 side and move to the second combustion chamber 11 side. When the combustion of the first combustion chamber 10 progresses, the pressure in the casing 1 rises to a predetermined pressure, and the 'explosive plate 14 bursts immediately' in the gas passage space P 2 to adjust the balanced clean gas, that is, to exhaust through each gas.

Description of the Invention (16) Thought. In addition, by forming the annular groove 16 into a V-shape, the cover fittings 34 can not bear the excess load caused by the extension process, and the eyelet can smoothly conform the annular protrusion 18 to the annular groove. Each of the grooves 16 has a pushing shape of 16 a, 16 b. Furthermore, the measure of forming the ring-shaped protrusion 18 by extension processing can be simply processed to seal and lock each of the opening sides 5 '6 of the outer cylinder fitting 2 and each of the cover fittings 3' 4 at the same time. The cover fittings 3, 4 are positioned at the respective open sides 5, 6 of the outer cylinder fitting 2. In addition, when the extension processing is performed, the flanges 15 of the respective cover fittings 3 ′ 4 limit the deformation of each of the open end sides 2 b of the outer cylinder fitting 2, so that the annular protrusions 18 can surely follow the annular grooves. Each of the grooves 16 has a pushing shape of 16 a, 16 b. In addition, although the gas generator S of the present invention is described as an example for expanding and deploying an airbag for a side impact, it is not limited to this, and can be applied to the expansion of an airbag for an assistant seat installed in an instrument panel. Expander. An example of the gas generator for the assistant's seat is shown in Fig. 5. It is to be noted that the same reference numerals in Fig. 5 as those in Figs. 1 to 4 indicate the same parts. The gas generator P 'in FIG. 5 is formed by inserting each of the cover fittings 3, 4 into each of the open sides 5, 6 to which the outer cylinder fitting 2 belongs, so as to constitute a relatively long cylindrical casing 1. As shown in FIG. A cylindrical filter fitting 9 is arranged in the sealed space P 1 in the housing 1 along the entire space in the axial direction, and a gas generating agent 13 is contained in the filter fitting 9. In addition, the ignition means 34 is an igniter 4 5 installed on the cover fitting 4, and the igniter 4 5 is opposite to the igniter 4 5 and the paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ( Please read the precautions on the back before filling in this page.) Order 486438 A7 B7 V. Description of the invention (17) The composition of the flame transfer agent 4 6 into the filter accessory 9. Then, an annular groove 16 is formed on each of the cover fittings 3 and 4, and an elastic ring 17 is installed in the annular groove 16. In addition, by performing an extension process on each of the open sides 5, 6 to which the outer cylinder fitting 2 belongs, a protruding annular protrusion 18 is formed in the annular groove 16. The annular protrusion 18 has a structure in which the elastic sealing ring 17 is elastically connected to the annular groove 16 and is fitted along the shape of the annular groove. In the gas generator P in FIG. 5, when the collision sensor detects the collision of the car, even if the ignition device 45 is energized and ignited, the fire retardant 46 is set on fire. The flame of the flame transfer agent 46 is then sprayed out into the filter fitting 9 by forcibly causing the gas generating agent 13 to catch fire and generate high temperature gas. Then, the 'high-temperature gas flows into the filter fitting 9 where it is cooled and trapped slag', and is then discharged into the airbag by the blasting plate 14 ruptured at a predetermined pressure through each gas discharge hole 2a. As described above, the same effects as those shown in Figs. 1 to 4 can also be obtained in the gas generator P for the assistant seat. Although the gas generators S and P of the present invention are described in terms of openings at both ends of the outer cylinder fitting 2, it is also feasible to select the outer cylinder fitting 2 having only one opening. The shape of the annular groove 16 is not limited to the V-shape, as long as the cross-section is concave, and those having a V-shape and a semi-circular shape may be used. The shape of the annular groove 16 can be as shown in FIG. 6. In Fig. 6, the annular groove 16 is formed by a V-shape opening around the inner periphery of the outer cylinder fitting 2 and a concave shape continuous with the V-shape. The circular groove 16 has a V-shaped inclination angle Θ set at 0 = (Please read the precautions on the back before filling out this page) Order printed by the Intellectual Property Bureau Staff Consumer Cooperatives of the Ministry of Economic Affairs This paper applies to China National Standard (CNS) A4 specification (210X297 mm) -20- S6436 A7 B7 V. Description of the invention (18) The range of 40 ~ 50 ° is ideal. The ratio h / d of the thickness d of the outer cylinder fitting 2 to the depth h of the annular groove 16 is preferably set to 2 or less. The amount of protrusion f of the annular protrusion 18 is preferably set to 0. 7 0 to 1 · 〇 〇 X d. Then, the elastic sealing ring 17 is installed in the recessed shape, and an extension process is performed around the outer cylinder fitting 2 to form a ring-shaped protrusion 18. In addition to the V-shaped fitting of the annular grooves 16 in conformity with the annular protrusion 18, the elastic ring 17 is elastically connected to the concave shape. With this, the elastic sealing ring 17 is lifted before it is not deformed excessively, that is, it is not flattened, and the seal is locked and positioned exactly as shown in FIGS. 1 to 5, and it can prevent falling off. In addition, the concave-shaped portion of the annular groove 16 in Fig. 6 is only required to have a concave cross-section, and thus a U-shape, a semicircular shape, or the like may be used. At this time, in order to apply the extension processing on the outer cylinder fitting 2 so that the annular protrusion 18 is firmly locked with the annular groove 16, the annular groove 16 is on the inner periphery of the outer cylinder fitting 2. The side is ideally made into a V shape, and the inclination angle is set to 0 = 40 ~ 50. . The depth h of the U-shaped and semi-circular annular grooves 16 refers to the distance from the inner peripheral opening of the outer cylinder fitting 2 to the bottom thereof. Furthermore, in the gas generators S and P of the present invention, the gas generator 13 is ignited and burned by a single ignition means 3 4 will be described, but the ignition means is installed on the cover fitting 3 of the casing 1 That is, it is also feasible to adopt a structure that can control the inflation and deployment of the airbag by installing ignition means on both shaft ends. Then, properly select the two ignition means to power on and control the fire. The paper size is controlled by the Chinese National Standard (CNS) A4 (210 X 297 mm) (please read the precautions on the back before filling out this page}, 11 Economy Printed by the Intellectual Property Cooperative of the Ministry of Intellectual Property, 21 4S6436 A7 B7 V. Description of Invention (19) (Please read the precautions on the back before filling out this page) The expansion of the capsule. The large amount of gas generated in the combustion chamber caused the airbag to inflate and expand rapidly. It also 'borrowed and fired with some time difference from the ignition means, so that the airbag was inflated and expanded with a small amount of gas generated in the combustion chamber during the initial stage of deployment' after a small time gap. Then, a large amount of gas generated in the combustion chamber is rapidly expanded and expanded. [Effect of the Invention] According to the gas generator of the present invention, since the cap fitting is positioned on the opening side of the outer cylinder fitting, there is no processing of the inner periphery of the outer cylinder fitting It is necessary to thicken the outer tube fittings along with the shoulder blocking parts and the processing of the shoulder blocking parts. Also, it does not belong to the outer tube fittings. Beyond the necessary thickening type, it can provide products that meet the requirements of small size, light weight and low price. In addition, it can also prevent high temperature and high pressure gas generated by the combustion of gas generating agent, which can cause the cap parts to be replaced from the outer tube parts.
