The inflator includes a filter for collecting hot combustion residues so that the airbag is not damaged during inflation. As this type of filter, a wire mesh formed by knitting a metal wire such as a stainless steel wire into a knitted shape is formed into a predetermined shape, and a filter obtained by compression-molding the wire mesh has been proposed and put into practical use. Since the knitted wire mesh has minute and complicated stitches, it is advantageous in forming fine and complicated voids in the filter, which have a high ability to collect combustion residues, and are not deformed by generated gas pressure. This is advantageous in that a large shape retention strength can be imparted to the filter.

There is disclosed an inflator filter formed by folding in such a manner as to be overlapped on the outer periphery of a wire mesh, and compressing in the length direction a cylindrical multifold wire mesh obtained by repeating such folding a plurality of times.

開示されている。In Japanese Patent Application Laid-Open No. 1-293112, a donut-shaped annular body is formed by wrapping a knitted cylindrical wire net of a metal wire having a wire diameter of 0.1 to 0.4 mm. It is disclosed that an annular body is compression molded to form a cylindrical filter for an inflator. Furthermore, in JP-A-4-66348, a wire diameter of 0.1 to
It discloses that at least two wire meshes of 0.35 mm are aligned and braided into a desired shape, for example, a hollow cylindrical shape, and this is compression-molded to form an inflator filter.

りを生じる危険がある。The conventional filter for an inflator disclosed in the above publication is formed of a metal wire having a small wire diameter. This is because, in general, a filter composed of a metal wire with a small wire diameter may have a higher ability to capture combustion residues, but if the wire diameter of the metal wire is large, knitting becomes difficult, Also, it is considered that when the knitted wire netting is folded or bag-wrapped, forming becomes difficult when the diameter of the metal wire is large. However, there is a recent tendency to omit thick wire mesh that cools the generated gas before the generated gas enters the filter.In such an inflator, a filter made of a metal wire having a small wire diameter is not suitable for the high temperature generated gas in the inflator. There is a risk that the metal wire is melted and the filter is clogged.

簡単には行い難く、特別な圧縮装置が必要になる。Further, as described above, the forming operation of folding a cylindrical knitted metal mesh into multiple layers in a cylindrical shape or the forming operation of bag winding is troublesome, and there is a problem that it is difficult to automate easily. And, as the wire diameter of the metal wire increases, these forming operations become more difficult. When a donut-shaped annular body is formed into a cylindrical shape and compressed, it is necessary to compress the annular body not only in its height direction but also in the width direction. A compression device is required.

There is a risk of causing. This variation in density is more likely to occur as the diameter of the metal wire increases, and tends to increase.

It is an object of the present invention to provide a method for manufacturing a filter for a flatter, which can be easily performed and can be easily automated.

A hollow cylindrical metal mesh obtained by knitting a metal wire of 45 mm to 0.6 mm to form a cylindrical metal mesh and winding a band obtained by folding the metal mesh into a mandrel having a predetermined outer diameter is used as the cylindrical metal mesh. And compression from both sides in the height direction.

属線ではメリヤス編みが困難になる。In the method of manufacturing a filter for an inflator according to the present invention, a knitted knitted fabric capable of forming fine and complicated voids having a high ability to trap combustion residues and providing a large shape-retaining strength which is not deformed by generated gas pressure. While maintaining the advantages of the above, a relatively large metal wire having a wire diameter of 0.45 mm to 0.6 mm is used so that there is no danger of the metal wire being melted down by the high-temperature gas generated by the combustion of the propellant. In the case of a metal wire having a wire diameter of less than 0.45 mm, there is a risk of melting by a high-temperature generated gas, and in the case of a metal wire having a wire diameter of more than 0.6 mm, knitting becomes difficult.

の成形、圧縮に格別な選択と工夫がなされている。In the present invention, since a metal wire having a relatively large diameter is used, forming and compressing the knitted wire netting in the conventional manner results in remarkably difficult and troublesome forming. The partial variation of the density in the applied filter becomes large. Therefore, in the production method of the present invention, special selection and devising have been made for the formation and compression of the knitted wire mesh without causing such disadvantages.

差が２．０mm以下であることが望ましい。That is, a cylindrical wire mesh obtained by knitting a metal wire having the above-mentioned wire diameter is formed into a belt-like body which is folded in two by a roll or the like, and the belt-like body is wound around a mandrel having a predetermined outer diameter to form a hollow. It is formed into a cylindrical wire mesh. Then, the hollow cylindrical metal mesh body is pressed and compressed from both sides in the height direction in order to make the density of the obtained filter uniform. In order to facilitate compression and make the density of the obtained filter uniform, it is desirable that the difference in thickness between the hollow cylindrical metal mesh before compression and the hollow cylindrical metal mesh after compression is small, and after the hollow cylindrical metal mesh is compressed. Is slightly larger than the thickness before compression, and the difference between them is desirably 2.0 mm or less.

る。If the difference in thickness is large, a wide band formed from a large-diameter cylindrical wire mesh is wound to increase the degree of compression in order to obtain a filter having a predetermined thickness and a predetermined density. It is necessary to increase the size of the mold for compression, and the variation in density is increased. On the other hand, if the thickness of the hollow cylindrical metal mesh before compression is larger than the thickness of the desired filter, it is necessary to compress the hollow cylindrical metal mesh in the thickness direction. Equipment is required.

The number of windings, etc., when winding the formed band on a mandrel is selected. However,
If the number of windings increases, voids between the winding layers increase, and the density of the resulting filter tends to vary. Therefore, it is preferable to use double or quadruple winding.

成する金属の密度である。In the production method of the present invention, the density of the obtained filter is adjusted to be in a range of 2.5 g / cm 3 (porosity 68%) to 4.5 g / cm 3 (porosity 43%). ,
It is preferable to select the conditions for molding and compression. The density is 2.
When the density is less than 5 g / cm 3 , the filter effect is poor and the shape retention strength of the filter is also insufficient.
This is because if it exceeds cm 3 , the gas will have too high a gas flow resistance through the filter. The porosity C (%) is defined by the following equation. C = 100 (ρ 0 −ρ) / ρ 0 where ρ is the density of the filter, and ρ 0 is the density of the metal constituting the filter.

Has a slightly smaller diameter than the inner diameter of the hollow cylindrical metal mesh body 6. Therefore, the thickness W2 of the filter 12 formed by compression using the compression mold 7 is formed slightly larger than the thickness W1 of the hollow cylindrical metal mesh body, but the difference is preferably 2.0 mm or less. . The degree of compression in the compression molding is selected so that the density of the obtained filter is within the above range. For example, the height of the hollow cylindrical metal mesh body 6 before compression is 100 to 105 mm, and the height after compression is 100 mm. Compress to 28-30 mm.
