The above-mentioned conventional tether belts, tethers, and other connecting bands were bent at both ends along the face of each panel facing each other, and these bent portions were joined to each panel by sewing or the like. When the airbag is inflated, the facing panels move away from each other. Thereby, a connection belt | band | zone exhibits a U-shaped form inside an airbag including the joined bending location.

When the connection band exhibits a U-shape due to the inflation of the airbag, the tension acts on the connection band at the same time as the tension acts along the panel surface. In other words, tension is applied to the bent portion that secures the bonding from two different directions: a direction along the panel surface and a disposition direction of the connecting band away from the panel surface toward the inside of the airbag. Thereby, there existed a subject that joining, such as sewing in a bending location, might be destroyed.

If the joint is broken, the function that the tether belt or other connection band should perform is lost, and the airbag as an occupant protection device cannot exhibit proper performance.

The present invention was devised in view of the above-described conventional problems, and appropriately applies stress generated at the joint between the panel and the connection band where tension acts both in the direction along the panel surface and in the arrangement direction of the connection band. It is an object of the present invention to provide a vehicle airbag structure and a vehicle side airbag device that can be dispersed in the vehicle, can improve the strength of the joint, and can appropriately operate the airbag.

FIG. 2 is a cross-sectional view taken along line AA in FIG. FIG. 2 is a cross-sectional view taken along line BB in FIG. It is principal part sectional drawing when the side airbag of the vehicle airbag structure applied to the vehicle side airbag apparatus shown in FIG. 1 expand | deploys.

It is explanatory drawing which shows the modification of the airbag structure for vehicles which concerns on this invention, and the side airbag apparatus for vehicles.

Hereinafter, a preferred embodiment of a vehicle airbag structure and a vehicle side airbag device according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a side view of a vehicle airbag structure and a vehicle side airbag device according to the present embodiment, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. FIG. 4 is a cross-sectional view taken along line BB, FIG. 4 is a cross-sectional view of the main part when the airbag of the vehicle airbag structure applied to the vehicle side airbag device shown in FIG. FIG. 3 is a partial cross-sectional view corresponding to FIG. 2 when the airbag of the vehicle airbag structure applied to the vehicle side airbag device shown in FIG. 1 is deployed and inflated.

In the present embodiment, the side airbag 1 housed inside the vehicle seat is illustrated as an airbag. When the inflator gas is introduced into the side airbag 1, the side airbag 1 jumps out from the inside of the seat toward the occupant side, expands and inflates to protect the occupant from impact.

As shown in FIG. 1, the side airbag 1 is formed into a bag shape that swells when gas is introduced by sewing S1 the peripheral edge of the facing panel 2 except the inflator mounting portion 3. The panel 2 is formed of a flexible cloth material or the like.

The side airbag 1 may be formed into a bag shape by folding one panel 2 or may be formed into a bag shape by overlapping two panels 2. Of course, a plurality of panels 2 may be formed. In the illustrated example, the panel 2 is configured by stacking two cloth pieces 4 (see FIGS. 2 to 5).

As described above, the side airbag 1 may be provided with a tether or a separation wall for the purpose of adjusting the expansion form or dividing the interior into a plurality of chambers. Both ends are joined to the facing panel 2 of the bag 1 and provided in the form of a connecting band that connects the panels 2 to each other.

In the present embodiment, the tether 5 is exemplified as the connection band. As will be described later in detail, as shown in FIGS. 1 and 2, the tether 5 has one end sewn on the panel surface 2 a of one panel 2 of the facing panel 2 and the other end on the panel surface 2 a of the other panel 2. Sewing S <b> 2 is performed so that the panels 2 are connected to each other so as to connect the panels 2 to each other.

The tether 5 is composed of a plurality of flexible cloth materials 6 having at least two sheets, which are overlapped. In the illustrated example, the tether 5 is configured by overlapping four cloth materials 6.

In the tether 5 composed of four cloth materials 6, in the length direction (direction spanning between facing panels 2; see FIG. 4), the four cloth materials 6 are placed at appropriate positions from both ends to the center. The 1st junction part 7 is formed by sewing S3 collectively.

In other words, the first joint portion 7 is an intermediate portion (region indicated by M in the drawing) of the tether 5 along the direction in which the panels 2 are connected to each other, and is a portion where the cloth materials 6 are sewn together.

The sewing S3 forming the first joint portion 7 is made along the width direction of the tether 5 (direction along the panel surface 2a; see FIG. 4), as shown in FIG. In the illustrated example, the first joint portion 7 is set at two locations, but may be at one location.

As shown in FIG. 2, both ends of the tether 5 are divided into two sets of the first set G1 and the second set G2 in the vicinity of the end portions 6a of the plurality of pieces of the cloth material 6, and The vicinity of the end 6a is sewn S2 on each panel 2 at two different locations, whereby two second joints 8 are formed on the tether 5.

In other words, the second joint portion 8 is formed on the end portion 6a side of the cloth material 6 from the first joint portion 7 toward the panel 2 (along the direction in which the panels 2 are connected to each other). The vicinity of the end portion 6a is divided into two groups of a first group G1 and a second group G2, and the vicinity of the end portion 6a of each group is a portion sewn on the panel 2. Thus, the tether 5 is sewn S2 on each panel 2 with both ends divided into two forks.

The tether 5 may be an even number or an odd number as long as a plurality of cloth materials 6 are overlapped. What is necessary is just to set suitably how to divide the plurality of cloth materials 6 into two sets according to the required strength. For example, when the cloth material 6 is an odd number, for example, three sheets, two sets of two sheets and one sheet, for example, for five sheets, two sets of three sheets and two sheets or two sets of four sheets and one sheet are used. And it is sufficient. Even when the fabric material 6 is an even number, for example, in the case of six sheets, it is not limited to two sets of three sheets, and may be two sets of four sheets and two sheets or two sets of five sheets and one sheet.

The sewing S2 that forms the second joint portion 8 is provided along the width direction of the tether 5 along the direction in which the first joint portion S3 is formed, preferably in parallel with each other. The two second joints 8 and the first joints 7 do not have to be completely parallel, and may be formed side by side in approximately the same direction.

Thereby, the tether 5 has two second joints 8 for one panel 2 at one end in the length direction, and two second joints 8 for the other panel 2 at the other end. And two first joints 7 at the center of the tether 5 itself. Unlike the illustrated example, the tether 5 may be configured to have only two second joint portions 8 for any one of the panels 2. In this case, the tether 5 (a plurality of cloth materials 6) is sewn to the other panel 2 at a single location.

When a force acts in the direction of pulling the tether 5 away from the panel 2 and a force acts in the opposite direction on both sides of the tether 5 on the panel surface 2a, between the first joint 7 and the two second joints 8, A tension T (see FIG. 5) for separating them is generated.

Due to this tension T, the tether 5 is surrounded by the tether 5 and each panel 2 in the cross section along the width direction of the tether 5 in relation to each panel 2, and the panel portion between the two second joints 8 is one side. Thus, a space C having a substantially triangular cross section is formed in which the two tether portions between each second joint portion 8 and the first joint portion 7 are two sides (see FIGS. 4 and 5).

At this time, the

joints

7 and 8 constitute vertices having a substantially triangular cross section. The force acting in the direction of separating the tether 5 from the panel 2 is transmitted from the first joint 7 to the two second joints 8. Further, the force acting along the panel surface 2 a is transmitted from each second joint 8 to the first joint 7.

When the side airbag 1 is inflated, when the force in the direction of pulling the tether 5 away from the panel 2 does not act, almost the force acts on the second joint 8 from the panel 2. In order to avoid this, it is set corresponding to the natural length of the panel 2 between the joints 8 in the inflated state of the side airbag 1.

The two distances from the first joint 7 to the second joints 8 may be set as appropriate. If these two distances are substantially equal, a space C having a substantially isosceles triangular section is formed. The Moreover, if the distance from the 1st junction part 7 to the 2nd junction part 8 and the distance between the two 2nd junction parts 8 are set substantially equal, the space C of a cross-section equilateral triangle shape will be formed. Of course, the space C having a substantially unequal triangular cross section may be used.

Next, the operation of the vehicle airbag structure and the vehicle side airbag apparatus including the vehicle airbag structure according to the present embodiment will be described. When the folded side airbag 1 is deployed and inflated (indicated by arrow E in FIG. 2), the tether 5 folded between the panels 2 also extends in the length direction, and is shown in FIGS. Thus, in each panel 2, the tension T acts along the panel surface 2 a, and at the same time, the facing panels 2 are separated from each other and the tension T acts on the tether 5.

These tensions T act so as to separate the three

joints

7 and 8 on each panel 2 side. The tension T acting on the tether 5 is transmitted from the first joint 7 to the two second joints 8 sewn S2 on each panel 2 and is borne at two locations on each panel 2. Depending on the tension T acting on the tether 5, the tension T acting along each panel surface 2 a is transmitted from the two second joints 8 to the first joint 7 of the tether 5 and is borne by the tether 5. The

In this way, when the side airbag 1 is inflated and the tension T acts along the panel 2, and when the facing panel 2 is separated and the tension T acts on the tether 5, the tether sewn S <b> 2 on each panel 2. Since both ends of 5 are connected to each panel 2 together with the panel 2 so as to form a space C having a substantially triangular cross-section, the stress generated at the joint between the tether 5 and the panel 2 is subjected to three joints. The

parts

7 and 8 can be divided and dispersed.

That is, by clearly configuring the three vertices and the three sides constituting the space C having a substantially triangular cross section, it is possible to avoid stress concentration on one point and to ensure an appropriate stress distribution function. Can do.

As a result, the strength of the joint portion between the panel 2 and the tether 5 can be improved, the joint portion can be prevented from being broken and the side airbag 1 can be operated appropriately, and the passenger protection performance can be appropriately secured. can do.

If the space C having a substantially isosceles triangle shape is formed by setting the distances between the three

joints

7 and 8 that are the vertices of the space C having a substantially triangular cross section, compared to the case of the substantially isosceles triangle shape in cross section, The balance of stress dispersion can be improved. In this case, the length of one side of the triangular shape shown between the two

second joints

8 and 8 is the same as the length shown between the first joint 7 and the second joint 8. It is preferable that the length is shorter than the length of one side. Thereby, stress can be more effectively dispersed than at least a tether having no space C, and the bonding strength of the tether 5 can be improved. If the space C has a substantially equilateral triangular cross section, ideally, the stress can be evenly distributed by one third and the strength can be improved most efficiently.

FIG. 6 shows a modification of the above embodiment. In the above embodiment, the case where the tether 5 is formed by superimposing the four cloth materials 6 is exemplified, but the tether 5 may be composed of a plurality of cloth materials 6 at least. The two cloth materials 6 need only overlap at the sewing location S3 (intermediate portion M of the tether 5 along the direction in which the panels 2 are connected to each other), and need to be able to overlap over the entire length in the length direction of the tether 5 between the panels 2. There is no. In the modified example, two cloth materials 6S shorter than the cloth material 6L are provided on the tether 5 (the cloth material 6L) with respect to one cloth material 6L provided so as to be bridged between the facing panels 2. Sewing S3 is performed at an appropriate position from the middle portion M, that is, from the center. The sewing location S3 between the

fabric materials

6L and 6S is the first joint portion 7, and the vicinity of the end portion 6a of each

fabric material

6L and 6S heading from the first joint portion S3 toward the panel 2 and the sewing location of each panel 2. S2 is the second joint 8.

Even in such a modification, the

cloth materials

6L and 6S are sewn S3 to each other at the intermediate portion M of the tether 5 which is composed of a plurality of

cloth materials

6L and 6S along the direction of connecting the panels 2 to each other. The first joint portion 7 and the end portions 6a of the plurality of

cloth materials

6L and 6S on the side of the end portions 6a of the

cloth materials

6L and 6S facing the direction of at least one panel 2 from the first joint portion 7 are the first. The pair G1 and the second set G2 are divided into two sets, and the vicinity of the end portion 6a of the

cloth material

6L, 6S of each set is sewn S2 on the panel 2 along the direction in which the first joint portion 7 is formed. In addition, the tether 5 having the two second joint portions 8 can be configured. Or the 1st junction part 7 comprised from the

cloth material

6L, 6S of several sheets, and

cloth material

6L, 6S mutually sewn S3 in the intermediate part M of the tether 5 along the direction which connects panels 2 mutually, and 1st On the end portion 6a side of the

cloth materials

6L, 6S facing the direction of at least one panel 2 from the one joint portion 7, the vicinity of the end portions 6a of the plurality of

cloth materials

6L, 6S is the first set G1 and the second set G2. The panel is divided into two groups, and the vicinity of the ends 6a of the

respective cloth materials

6L and 6S of each group is located at an approximately equal distance from the first joint 7 along the direction in which the first joint 7 is formed. The tether 5 having the two second joints 8 sewn S2 in FIG.

FIG. 6A shows an example in which two short cloth materials 6S are sewn S2 to the panel 2 on the same side with a single cloth material 6L provided so as to be bridged between the panels 2. FIG. (B) is an example in which one cloth material 6L provided so as to be bridged between the panels 2 is sewn S2 to the panel 2 on a different side with respect to two short cloth materials 6S.

In the above embodiment, the tether 5 is exemplified as the connection band, but a separation wall that divides the inside of the side airbag 1 into a plurality of chambers may be used.

In the above embodiment, the case where the size of the space C having a substantially triangular cross section is constant in the width direction of the tether 5 (connection band) has been described. The size of the space C is the largest at any one of the maximum positions in the width direction of the tether 5, and the first joint 7 and the two second joints 8 are sewn so as to gradually decrease from the maximum position. The positions S2 and S3 may be set so as to gradually approach the width direction of the tether 5.

In the above embodiment, the side airbag 1 is exemplified as the airbag, but it is needless to say that the airbag may be applied to a curtain airbag, a driver seat airbag, or a passenger seat airbag.

In the present embodiment, the panel 2 and the connecting band forming the tether 5 and the like are formed of the flexible cloth material 6 and the like, and these joints are performed by sewing S1 to S3. It is difficult to completely define. A substantially triangular shape, a substantially isosceles triangular shape, or a substantially equilateral triangular shape is not only a triangular shape in which each side is a perfect straight line, but also a triangular shape even if the straight line is broken and has a side that includes a curved portion. A triangular shape that can be regarded as a shape. The substantially equal distance or the substantially equal distance means not only a complete equal distance but also a state including some errors and deviations as long as the desired performance can be satisfied.

The vehicle airbag structure and the vehicle side airbag device described above are preferable examples of the present invention, and other exemplary embodiments can be implemented or performed by various methods. In particular, the present invention is not limited to the detailed shape, size, configuration, and the like of the components shown in the accompanying drawings unless otherwise stated in the present specification. In addition, expressions and terms used in the present specification are for the purpose of explanation, and are not limited thereto unless otherwise specified.
