Description

The present invention relates to a side airbag device that restrains a vehicle occupant from the side.

Airbag devices are almost standard equipment on recent vehicles. The airbag device is a safety device that operates in an emergency such as a vehicle collision, and expands and deploys the airbag cushion by gas pressure to receive and protect the occupant.

There are various types of airbag devices depending on the installation location and application. For example, a front airbag device is provided in the center of the steering wheel to protect the driver from a front-rear collision. In addition, a curtain airbag device is installed near the ceiling above the side window and a side airbag device is installed on the side of the seat to protect the occupants from the impact from the vehicle width direction due to a side collision or the like. Has been done.

The current airbag cushion has been devised in various factors such as the degree of deployment behavior and the injury value to the occupant. For example, in the side collision airbag device (side airbag) described in Patent Document 1, a strap 60 (upper strap portion 61, lower strap) is used on the outside of the airbag 40 in order to suppress unnecessary movement of the airbag 40. Section 65) is provided.

Japanese Unexamined Patent Publication No. 2016-83955

As described above, the airbag cushion is also required to reduce the injury value to the occupant. For example, the load received by the occupant from the airbag cushion increases in proportion to the load at the time of restraint. The rigidity of the airbag cushion depends on the output of the inflator, which is the gas supply source, but changing the output of the inflator itself according to the load is not an efficient means in terms of structural complexity and cost.

In view of such a problem, an object of the present invention is to provide a side airbag device capable of adjusting the rigidity of an airbag cushion with a simple configuration.

In order to solve the above problems, a typical configuration of the side airbag device according to the present invention is an inner panel that expands and expands on the side of the seat of the vehicle and is provided on the side of the occupant seated in the seat, and an inner. An airbag cushion formed in a bag shape by an outer panel located on the side opposite to the occupant of the panel, an intermediate panel connected to each edge of the inner panel and the outer panel in a predetermined range, and an airbag cushion in the intermediate panel. A breakable seam that joins the edges of the inner panel and the outer panel over a predetermined range while being folded inside, and a band-shaped one or both of the inner panel and the outer panel provided on the outer surface of each. One end of the tether is joined to the inner panel or the outer panel in the vicinity of the intermediate panel, and the other end is joined to a predetermined position on the outer surface of the inner panel or the outer panel. The seam is broken by the force when the structures of the above are in contact with each other, so that the intermediate panel is released, the volume of the airbag cushion is increased, and the internal pressure is lowered.

With the above configuration, the airbag cushion has a mechanism in which the rigidity changes according to the degree of load when the occupant is restrained. Therefore, for example, when the collision speed is high, the airbag cushion can be softened more than usual, and the injury value of the occupant can be suppressed.

One end of the above tether may be joined in the vicinity of the seam. This configuration allows the seams to be efficiently broken through the tether.

One end of the above tether may be joined over the seam. With this configuration as well, the seam can be efficiently broken through the tether.

One end of the above tether may be joined to the inner panel or outer panel by a seam. With this configuration as well, the seam can be efficiently broken through the tether.

The above predetermined range may include at least the front side of the airbag cushion. By providing the intermediate panel and the seam on the front side of the vehicle, it becomes possible to preferably realize an airbag cushion with adjustable rigidity.

The above-mentioned predetermined range may include a continuous range from the front side of the vehicle to the upper side of the vehicle of the airbag cushion. This configuration also makes it possible to suitably realize an airbag cushion with adjustable rigidity.

The above tether includes a first tether provided on the outer surface of the inner panel, which is the occupant along the inflated inner panel of the airbag cushion before the airbag cushion restrains the occupant. It is preferable that the length is such that it is stretched to the side. The first tether of this configuration has a tension that is stretched along the convex shape of the inner panel, that is, a tension that does not change the shape of the inner panel when the airbag cushion is simply inflated before the occupant is restrained. I'm nervous. Therefore, with the above-mentioned first tether, it is possible to break the seam only when the occupant comes into contact with it, without affecting the occupant binding force of the airbag cushion or breaking the seam by itself. ..

The above tether includes a second tether provided on the outer surface of the inner panel, which is with the occupant along the inflated outer panel of the airbag cushion before the airbag cushion restrains the occupant. May have a length that allows it to be stretched to the opposite side. The second tether of this configuration also has a tension that is stretched along the convex shape of the outer panel, that is, a tension that does not change the shape of the outer panel, when the airbag cushion is simply inflated before the occupant is restrained. get nervous. Therefore, in the case of the above-mentioned second tether, the seam is broken only when it comes into contact with the occupant or other structures without affecting the occupant binding force of the airbag cushion or breaking the seam by itself. Will be possible.

The side airbag device may further include one or more baffles that are laid across the inner panel and the outer panel in the vehicle width direction inside the airbag cushion. By providing the baffle, it is possible to limit the thickness of the airbag cushion in the vehicle width direction and prevent the seam from breaking during normal expansion and deployment.

The one or more baffles described above include a rear baffle arranged on the rear side of the vehicle inside the airbag cushion, and the other end of the tether may be overlapped and joined to the rear baffle. With this configuration, the other end of the tether can be fully joined to the airbag cushion, and force can be efficiently applied to the seam on one end side of the tether.

The one or more baffles described above may include a baffle that is longer in the vertical direction than in the vehicle width direction. The baffle having this configuration makes it possible to efficiently reduce the thickness of the airbag cushion in the vehicle width direction.

According to the present invention, it is possible to provide a side airbag device that allows the rigidity of the airbag cushion to be adjusted in a simple configuration.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in such an embodiment are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are designated by the same reference numerals to omit duplicate description, and elements not directly related to the present invention are not shown. To do.

FIG. 1 is a diagram illustrating the side airbag device 100 according to the embodiment of the present invention. In FIG. 1A, the side airbag device 100 and the seat 102 on the right side of the vehicle to which the side airbag device 100 is applied are illustrated from the left side in the vehicle width direction, that is, from the inside in the vehicle width direction (inside the vehicle). .. Hereinafter, in FIG. 1 (a) and all other drawings of the present application, the arrows F (Forward) and B (Back) are shown in the vehicle front-rear direction, and the arrows L (Left) and R (Right) are shown in the left and right directions in the vehicle width direction, respectively. The vertical direction of the vehicle is illustrated by arrows U (up) and D (down), respectively.

As illustrated in FIG. 1A, the side airbag device 100 is installed inside the vehicle outside of the seat back 104 of the seat 102 in the present embodiment. The side airbag device 100 includes an airbag cushion (cushion 106) that restrains an occupant and an inflator 108 that supplies gas to the cushion 106. The cushion 106 is wound or folded before operation, and is housed in a housing or the like built in the seat back 104. Since the cushion 106 in the stored state is covered with a seat cover or the like, it cannot be seen from the outside.

The inflator 108 is a gas generator, and in the embodiment, a cylinder type (cylindrical type) is adopted. The inflator 108 is contained in the rear portion of the rear chamber 112 of the cushion 106, which will be described later, in a direction that is longitudinally longitudinal along the seat back 104. The inflator 108 is electrically connected to the vehicle side, receives a signal from the vehicle side due to the detection of the impact, operates, and supplies gas to the cushion 106.

Currently popular inflators are filled with a gas generating agent and burned to generate gas, compressed gas is filled with gas to supply gas without generating heat, or combustion. There is a hybrid type that uses both gas and compressed gas. Any type of inflator 108 can be used.

The cushion 106 is attached to the seat back 104 by using two stud bolts 110a and 110b of the inflator 108. The stud bolts 110a and 110b penetrate the base cloth of the cushion 106 and are exposed to the outside, and are fastened and fixed to the frame or the like of the seat back 104.

FIG. 1B is a diagram illustrating a state of the cushion 106 of FIG. 1A after expansion and deployment. When the sensor provided in the vehicle detects an impact, an operation signal is sent to the inflator 108 to eject gas, and the cushion 106 expands and expands into the interior space by rejecting the skin and the like of the seat back 104 using the gas. ..

The cushion 106 expands and expands into an overall flat shape on the side of the seat. The outer surface of the cushion 106 is composed of an inner panel 106a on the side of the occupant seated in the seat in the vehicle width direction, an outer panel 106b on the side opposite to the occupant when viewed from the inner panel 106a, and an intermediate panel 128 described later. doing. Each panel is made from a base cloth, and is formed into a bag shape as a whole by sewing or gluing. It should be noted that the panels do not have to be independent of each other, and may be a continuous fabric as a whole. In that case, the cushion 106 can also be formed by, for example, weaving using OPW (One-Piece Woven).

In the present embodiment, a band-shaped first tether 116 is stretched on the outer surface of the inner panel 106a. The first tether 116 is provided so as to extend in the front-rear direction of the vehicle, and in addition to suppressing the swing of the cushion 106 when it is expanded and deployed, the seam 130 (see FIG. 2B), which will be described later, applies a load from the occupant. ) Has a role to convey.

FIG. 2 is a diagram illustrating the airbag cushion (cushion 106) of FIG. 1 (b) alone. FIG. 2A illustrates the cushion 106 partially penetrating from the inside of the vehicle to the inside.

The inside of the cushion 106 is divided into a rear chamber 112 and a front chamber 114 by a baffle 118. The baffle 118 is a wall-shaped portion formed by using the same type of base cloth as the inner panel 106a or the like, and is spread over and connected to the inner panel 106a and the outer panel 106b in the vehicle width direction. The baffle 118 is provided with a plurality of vent holes 120, 122 and the like. The vent holes 120, 122, etc. are gas flow ports, and gas is passed from the rear chamber 112 side to the front chamber 114 side.

The rear chamber 112 is a portion of the cushion 106 located at the root, and is formed in the lower portion on the rear side of the vehicle. The rear chamber 112 has a shape elongated in the vertical direction along the seat back 104 (see FIG. 1B). The inflator 108 is built in the rear chamber 112. The capacity of the rear chamber 112 is smaller than that of the front chamber 114, and the pressure is quickly increased immediately after the inflator 108 is operated. The rear chamber 112 rapidly cleaves the epidermis of the seat back 104 (see FIG. 1B) and also accelerates the expansion and deployment of the entire cushion 106.

The front chamber 114 is a portion that expands and expands widely toward the front and the upper side of the rear chamber 112. The front chamber 114 expands and expands from the seat back 104 (see FIG. 1B) to a range in which an occupant in front of the vehicle exists, and positively restrains the occupant.

A plurality of baffles are also provided inside the front chamber 114. The baffles 124 to 126 are spread over the inner panel 106a and the outer panel 106b in the vehicle width direction, and limit the thickness of the cushion 106 in the vehicle width direction. In particular, the baffles 124 to 126 are configured to be longer in the vertical direction than in the vehicle width direction, so that the thickness of the cushion 106 in the vehicle width direction can be efficiently suppressed. By limiting the thickness of the cushions 124 to 126, the baffles 124 to 126 also prevent the seam 130, which will be described later, from breaking during normal expansion and deployment.

The intermediate panel 128 described above is folded inside the front chamber 114. The intermediate panel 128 is coupled to the inner panel 106a and the outer panel 106b from the front side of the vehicle to the upper side of the vehicle in a predetermined range. The intermediate panel 128 is normally fastened by the seam 130 in a folded state inside the front chamber 114, and is exposed to the outside when the seam 130 is broken by a load of a predetermined value or more from the occupant.

FIG. 2B is a cross-sectional view taken along the line AA of FIG. 2A. The seam 130 joins the edges of the inner panel 106a and the outer panel 106b to each other with the intermediate panel 128 folded inside the cushion 106. The seam 130 can be provided by sewing using a thread that breaks with a certain force, sewing that is eliminated by a certain force, or the like.

One end 116a of the first tether 116 is joined to the inner panel 106a in the vicinity of the intermediate panel 128 by a sewing portion 132. The other end 116b of the first tether 116 straddles a predetermined range of the outer surface of the inner panel 106a from one end 116a, and then is attached to the inner panel 106a by a sewing portion 134 at a position overlapping the rear baffle (baffle 126) on the rear side of the vehicle. It is joined. The baffle 126 is a baffle arranged as a rear baffle on the rear side of the vehicle inside the cushion 106. The other end 116b of the first tether 116 can be fully joined by the inner panel 106a by overlapping and joining the baffle 126.

As described above, the first tether 116 becomes tense when the cushion 106 expands and expands, and suppresses the swing of the cushion 106. Therefore, the length from the sewn portion 132 to the sewn portion 134 of the first tether 116 is shorter than the length from the portion where the sewn portion 132 is provided to the portion where the sewn portion 134 is provided on the inner panel 106a. With this configuration, the first tether 116 can be tensioned with an appropriate tension in the longitudinal direction when the cushion 106 is expanded and deployed.

In the present embodiment, the first tether 116 is provided so as to cover the range of the inner panel 106a that the occupant contacts, that is, the occupant restraint range. The first tether 116 not only suppresses the swing of the cushion 106, but also transmits the load received from the occupant to the seam 130 and functions as a factor for breaking the seam 130.

FIG. 3 is a diagram illustrating the state of the airbag cushion (cushion 106) before and after the break of the seam 130 of FIG. 2 (b). In the present embodiment, the rigidity of the cushion 106 can be adjusted according to the load from the occupant by using the first tether 116 and the seam 130.

FIG. 3A illustrates the state of the cushion 106 before the seam 130 is broken. The seam 130 continuously joins the inner panel 106a and the outer panel 106b over a predetermined range from the front side of the vehicle to the upper side of the vehicle.

In the cushion 106 in the state before restraining the occupant, the first tether 116 is set to be in a state of being convexly stretched toward the occupant side along the inner panel 106a of the expanded cushion 106. That is, the length from one end 116a (see FIG. 2B) of the first tether 116 to the other end 116b is such that when the cushion 106 expands and expands, it is strongly pulled to deform the inner panel 106a. In addition, the length is not such that it hangs down from the outer surface of the inner panel 106a, and the length is such that tension is generated so as to be convexly stretched toward the occupant along the outer surface of the inner panel 106a. With this length, the first tether 116 does not deform the cushion 106 to affect the occupant restraint force in the state where the cushion 106 is simply inflated before the occupant is restrained, and the seam itself. It is possible to break the seam 130 only when the occupant comes into contact with it without breaking the 130.

FIG. 3B illustrates the state of the cushion 106 after the seam 130 is broken. In FIG. 3B, an impactor 136, which is a test device simulating an occupant, is illustrated instead of the occupant. Since the first tether 116 is provided in the occupant restraint range, the occupant (impactor 136) comes into contact with the first tether 116. The load from the occupant at this time is also transmitted to the seam 130 via the first tether 116. When the load applied from the impactor 136 to the first tether 116 is larger than a certain level, the seam 130 is broken by the load. Then, the intermediate panel 128 is opened, and the volume of the cushion 106 is increased. As a result, the internal pressure of the cushion 106 is lowered, and the rigidity of the inner panel 106a is also lowered.

As described above, the cushion 106 of the present embodiment has a mechanism in which the rigidity changes according to the degree of the load when the occupant is restrained. Therefore, for example, when the collision speed is high, the cushion 106 can be made softer than usual, and the injury value of the occupant can be suppressed. The configuration using the first tether 116, the intermediate panel 128, and the seam 130 of the present embodiment is simpler than the mechanism for changing the output itself of the inflator 108 (see FIG. 1A, etc.). Therefore, the cost can be suppressed suitably.

In the present embodiment, the intermediate panel 128 and the seam 130 are provided from the vehicle front side to the vehicle upper side of the cushion 106, thereby increasing the volume of the cushion 106. However, the range in which the intermediate panel 128 and the like are provided is not limited, and the volume of the cushion 106 can be increased or decreased by increasing or decreasing the provided range.

In FIG. 2B, one end 116a of the first tether 116 is joined to the inner panel 106a by both the seam 130 and the sewn portion 132. However, one end 116a may be joined to the inner panel 106a only by the seam 130, or may be joined to the inner panel 106a only by the sewing portion 132. Even when one end 116a is joined to the inner panel 106a only by the sewing portion 132, the sewing portion 132 is provided in the vicinity of the seam 130 on the inner panel 106a, or the sewing portion 132 is provided so as to overlap the seam 130. As a result, the load from the occupant can be efficiently transmitted from the first tether 116 to the seam 130.

There is no limitation on the location of the other end 116b of the first tether 116, and it is sufficient that the first tether 116 can be installed so as to cover the occupant restraint range. The other end 116b may be appropriately joined to a predetermined portion of the inner panel 106a, but if it is overlapped with the sewn portion of the baffle 126 as in the present embodiment, more complete joining becomes possible, and one end 116a side to the seam 130. And the load can be transmitted efficiently.

(Modification example)
FIG. 4 is a diagram illustrating a modified example (cushion 200) of the airbag cushion (cushion 106) of FIG. 1 (b). Hereinafter, the same components as those already described will be omitted by assigning the same reference numerals. In addition, components having the same name as the components already described shall have the same function even if they have different symbols, unless otherwise specified.

FIG. 4A is a diagram illustrating the cushion 200 after expansion and deployment, corresponding to FIG. 1B. The cushion 200 is different from the cushion 106 (see FIG. 1B) in which the inner panel 106a is provided with the first tether 116 in that the second tether 202 is provided on the outer surface of the outer panel 106b as a band-shaped tether. The configuration is different. The second tether 202 is also provided so as to extend in the front-rear direction of the vehicle, and in addition to suppressing the swing of the cushion 200 when it is expanded and deployed, the seam 130 (FIG. 4B), which will be described later, applies a load from the occupant. It plays a role in communicating to (see).

FIG. 4B is a cross-sectional view of the cushion 200 at the position of the second tether 202 corresponding to FIG. 2B. In the second tether 202, one end 202a is joined to the outer panel 106b in the vicinity of the intermediate panel 128 by a sewing portion 204. The other end 202b of the second tether 202 is joined to the outer panel 106b by the sewn portion 206 at a position overlapping the baffle 126 on the rear side of the vehicle after straddling a predetermined range of the outer surface of the outer panel 106b from one end 202a. The other end 202b of the second tether 202 can be fully joined to the outer panel 106b by overlapping and joining the baffle 126.

The second tether 202 becomes tense when the cushion 200 expands and expands, and suppresses the swing of the cushion 200. Therefore, the length from the sewn portion 204 to the sewn portion 206 of the second tether 202 is shorter than the length from the portion where the sewn portion 204 is provided to the portion where the sewn portion 206 is provided on the outer panel 106b. With this configuration, the second tether 202 can be tensioned with an appropriate tension in the longitudinal direction when the cushion 200 is expanded and deployed.

In the cushion 200 in the state before restraining the occupant, the second tether 202 is set to be in a state of being convexly stretched on the side opposite to the occupant along the outer panel 106b of the expanded cushion 200. That is, the length from one end 202a to the other end 202b of the second tether 202 is not a length that is strongly pulled to deform the outer panel 106b when the cushion 200 expands and expands. Further, the length is not such that it hangs down from the outer surface of the outer panel 106b. That is, the length is such that tension is generated so as to be convexly stretched along the outer surface of the outer panel 106b on the side opposite to the occupant. With this length, the second tether 202 does not deform the cushion 200 to affect the occupant restraining force in the state where the cushion 200 is simply inflated before the occupant is restrained, and the seam itself. It is possible to break the seam 130 only when a load is applied when the occupant is restrained without breaking the 130.

FIG. 5 illustrates the state after the seam 130 (see FIG. 4B) of the airbag cushion (cushion 200) of FIG. 4A is broken. Since the second tether 202 is provided on the side opposite to the occupant, the occupant seated in the seat does not directly contact the second tether 202. Instead, the second tether 202 comes into contact with other structural parts, such as the door trim or pillars of the passenger compartment, when the occupant contacts the inner panel 106a and the entire cushion 200 is pushed away from the seat. There is. At this time, the load received from the other structure is also transmitted to the seam 130 via the second tether 202. When the load applied to the second tether 202 is larger than a certain level, the seam 130 is broken by the load. Then, the intermediate panel 128 is opened, and the volume of the cushion 106 is increased. As a result, the internal pressure of the cushion 106 is lowered, and the rigidity of the inner panel 106a is also lowered.

As described above, the cushion 200 of the modified example also has a mechanism in which the rigidity changes according to the degree of the load when the occupant is restrained. For example, when the entire cushion 200 is strongly pressed by the occupant when the collision speed is high, the cushion 200 is softened more than usual according to the load received from the door trim or the like, and the injury value of the occupant can be suppressed. ing. Even with the configuration using the second tether 202, the intermediate panel 128, and the seam 130, the cost is simpler than the mechanism for changing the output itself of the inflator 108 (see FIG. 4A, etc.). It can be suppressed suitably.

As a further modification, it is also possible to provide both the first tether 116 (see FIG. 1 (b)) and the second tether 202 (see FIG. 4 (a)) for one airbag cushion. is there. If the airbag cushion is equipped with the first tether 116 and the second tether 202 at the same time, it can handle the load received from the occupant side and the load received from the opposite side to the occupant from either direction. Will be possible. In other words, the airbag cushion of this configuration can handle both the load received from the side near the collision point (near side) and the load received from the side far from the collision point (far side). .. With this configuration, the seam 130 can be broken in response to a collision load from each direction, and the internal pressure and rigidity can be reduced more efficiently.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the claims, which naturally belong to the technical scope of the present invention. Understood.

Further, in the above embodiment, an example in which the airbag device according to the present invention is applied to an automobile has been described, but it can also be applied to an aircraft, a ship, or the like other than the automobile, and the same effect can be obtained. it can.

The present invention can be used for a side airbag device that restrains a vehicle occupant from the side.
