Description

  The present invention relates to a vehicle having an airbag.

  Conventionally, for example, as in the invention described in Patent Document 1, for the purpose of stabilizing and improving the deployment performance of an airbag, it is provided with a skin layer, a base layer, a resin layer, etc. There was a vehicle interior panel consisting of:

JP 2013-010455 A

  However, in recent years, in order to cope with various vehicle collision modes, for example, an airbag having a portion projecting in a specific direction from a part of a conventionally used airbag has been proposed. Therefore, there has been a demand for a vehicle in which an airbag having a protruding portion can be stably deployed.

  Therefore, the problem to be solved by the present invention is to provide a vehicle having an airbag that can be stably deployed even if the airbag has a protruding portion.

As a means for solving the above problems, a vehicle having an airbag according to the present invention is arranged in an interior member that forms an interior of a passenger compartment and the interior member, and the surroundings are broken or pushed away by pressure from the back side. a lid portion which is formed so as to open, is disposed on the back side of the lid portion, the first air bag can be deployed in the passenger compartment by opening the lid portion, from Rutotomoni first airbag is provided in the first air bag And a second airbag that is disposed in the vicinity of the back surface of the lid portion and can be projected from the first airbag, and on the back side of the lid portion that is opened when the first airbag and the second airbag are deployed. In order to equalize the force received by the lid from the first airbag and the second airbag , the time when only the first airbag reaches the back of the lid and the second airbag on the back of the lid The arrival time is long Only by a distance corresponding to the difference between the arrival time minute and a filler member disposed so as to protrude on the back side of the lid.

In the vehicle according to the present invention, the filling member is a protrusion that protrudes from the back surface of the lid portion toward at least one of the first airbag and the second airbag, or a spacer that is fixedly attached to the back surface of the lid portion. It is preferable.

In the vehicle according to the present invention, in the vehicle width direction, the second airbag is provided in a part of the first airbag, and the filling member has a vehicle width in a force that the lid receives from the first airbag and the second airbag. In order to make the variation in force along the direction uniform, it is preferable to arrange it so as to project to the back side of the lid portion by a distance corresponding to the difference in arrival time in the vehicle width direction .

In the vehicle according to the present invention, the second airbag before deployment is formed so that the arrival time to reach the lid portion is shorter than the first airbag before deployment, and the filling member faces the first airbag. It is preferable to arrange so as to project to the back side of the lid portion .

  According to the present invention, when deploying the first airbag and the second airbag projecting from the first airbag, the force that the interior member receives from the first airbag and the second airbag during deployment is It becomes non-uniform depending on the part. Since the force that the interior member acts from the first airbag and the second airbag can be made uniform by the filling member, the interior member can be uniformly and similarly to the airbag without the conventional second airbag. Therefore, even if the airbag has a protruding portion, a vehicle having an airbag that can be stably deployed can be provided.

  An embodiment of a vehicle having an airbag according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing a vehicle that can employ a vehicle having an airbag according to the present invention. FIG. 1A is a schematic view of a vehicle having an airbag to which the present invention is applied as seen from above. FIG. 1B is a schematic view of a passenger seat of a vehicle having an airbag to which the present invention is applied as viewed from the side.
In FIGS. 1A and 1B, the left side of the drawing is the front side, and the right side of the drawing is the rear side. Further, the vehicle 1 shown in FIGS. 1A and 1B is provided with a driver's seat and a steering wheel on the left side in the traveling direction.
Further, FIG. 2 is an enlarged perspective view of a part of the dashboard in which the airbag is accommodated.

As shown in FIG. 1A, the vehicle 1 includes a vehicle body 2, a driver seat 3, a passenger seat 4, a rear seat 5, a dashboard 6, a steering wheel 7, and an occupant protection device 8.
In addition, as shown in FIG. 1B, an occupant protection device 8 is provided in the passenger seat 4 in the vehicle 1. In the occupant protection device 8 shown in FIGS. 1A and 1B, the first airbag 9 and the second airbag 10 are in the deployed state, and the state before deployment is described with reference to FIG. It will be described later.
The dashboard 6 is one of the members forming the interior in front of the passenger compartment, and is an example of the interior member in the present invention.

The occupant protection device 8 includes a first airbag 9, a second airbag 10, a housing portion 11, and an inflator 12.
The first airbag 9 is a bag body that is disposed on the back side of the dashboard 6 and that can be deployed in the passenger compartment by opening the dashboard 6 so as to face the occupant M in a normal riding posture. The second airbag 10 is a bag body that is provided on the first airbag 9 and that can be deployed from the first airbag 9 to protrude. The accommodating portion 11 is a housing that is disposed on the back side of the dashboard 6 and accommodates the first airbag 9 and the second airbag 10 before deployment. The inflator 12 is an appropriate gas injection member, and inflates and deploys the first airbag 9 and the second airbag 10 by injecting gas into the first airbag 9 and the second airbag 10. be able to.
In addition, the 1st airbag 9 is an example of the 1st airbag in this invention, and the 2nd airbag 10 is an example of the 2nd airbag in this invention.

  Subsequently, as shown in FIG. 2, the occupant protection device 8 is accommodated in the dashboard 6 before deployment. A lid 13 is provided in front of and above the glove box 61 in the dashboard 6. The lid portion 13 is a portion opened by the first airbag 9 and the second airbag 10 in the dashboard 6, and is an example of an interior member in the present invention, similar to the dashboard 6. In the state before the deployment of the first airbag 9 and the second airbag 10, the lid 13 covers the accommodating portion 11 that accommodates the folded first and second airbags 9 and 10. .

In FIG. 2, a broken line illustrated around the lid portion 13 indicates a portion that is to be deformed, moved, or broken when the lid portion 13 is opened. Note that the first airbag 9 and the second airbag 10 can be deployed in a desired orbit by opening the lid portion 13 uniformly and uniformly.
In the present embodiment, examples of the form in which the interior member is opened include a form in which the interior member is broken and opened by a force received from the first airbag and the second airbag, and a form in which the interior member is pushed away from the location where the interior member is disposed. Can do. In the present embodiment, the lid 13 is opened when the periphery of the lid 13 is broken, and as a result, a part of the dashboard 6 is opened.
A groove portion 131 is formed in the broken line portion shown in FIG. 2 so as to be easily broken on the back surface of the lid portion 13. When the occupant protection device 8 is deployed, the lid 13 is broken along the groove 131 indicated by a broken line.

  The lid portion 13 is normally provided integrally with the dashboard 6 from the viewpoint of improving the appearance of the dashboard 6 and eliminating the driver's line-of-sight obstruction, but is provided separately if necessary. Also good. A center console 62 extending in the vehicle front-rear direction and the vehicle vertical direction is formed substantially integrally with the dashboard 6 at a substantially central portion of the dashboard 6 in the vehicle width direction.

  As shown in FIGS. 1 (A) and 1 (B), the occupant M can ride in the sitting position with the seat belt 14 mounted on the passenger seat 4. The first airbag 9 in the occupant protection device 8 is expanded in front of the occupant M when deployed, so that the occupant M can move to the dashboard when the occupant M moves forward due to inertia generated at the time of collision in a full lap collision or the like. 6 and the windshield can be prevented.

Further, in recent years, in order to cope with various vehicle collision modes, for example, an air bag having a shape in which the second airbag 10 protrudes from an inner portion of the first airbag 9 having a conventionally used shape in the vehicle width direction. A bag has been proposed. The second airbag 10 is, for example, an occupant M in a normal riding posture as shown in FIG. 1A from the rear end side of the first airbag 9 toward the rear and as shown in FIG. It is arranged so as to protrude at a height that is substantially the same as the height of the face of the occupant or at a height that is located to the side of the face of the occupant M when the occupant M falls down.
In particular, as shown in FIG. 1A, when a collision in the oblique direction from the front side of the driver's seat 3 with respect to the longitudinal direction of the vehicle, that is, a collision from the direction indicated by the white arrow occurs, the passenger on the passenger seat 4 side M tries to fall toward the center of the dashboard 6 and the center console 62. In this case, the occupant protection device 8 having the first airbag 9 and the second airbag 10 can prevent the occupant M from coming into direct contact with the center console 62 where particularly hard members are used.
As described above, the occupant protection device 8 having a portion that protrudes in a specific direction from a part of a conventionally used airbag protects the occupant M not only from a full wrap collision and an offset collision, but also from an oblique collision. can do.

  Next, FIG. 3 is a schematic view showing the back side of the dashboard 6 in which the occupant protection device 8 before deployment is accommodated. The occupant protection device 8 is deployed when the first airbag 9 and the second airbag 10 are inflated upward in FIG. As shown in FIG. 3, the occupant protection device 8 before deployment is folded and housed in the housing portion 11 so that the first airbag 9 and the second airbag 10 become smaller along the deployment direction.

  A member indicated by an alternate long and short dash line around the first airbag 9 and the second airbag 10 is a packaging bag body that wraps the first airbag 9 and the second airbag 10 before deployment. The packaging bag is broken when the first airbag 9 and the second airbag 10 are deployed.

  An inflator 12 is disposed at the bottom of the accommodating portion 11. The timing of gas injection from the inflator 12 is basically that an acceleration sensor provided at an appropriate position of the vehicle body detects an impact, the acceleration sensor inputs a detection signal to the ECU, and the ECU This is when a gas injection start signal is input.

  In the embodiment shown in FIG. 3, the number of inflators 12 is one, but is not particularly limited in the present invention. Basically, the number of inflators is often determined based on the capacity of the airbag. For example, even if two or more inflators are installed in the present embodiment, gas may be injected at the same time.

As shown in FIG. 3, the spacer 15 is arrange | positioned in one Embodiment of the vehicle which has an airbag which concerns on this invention. The spacer 15 is provided on the back side of the lid portion 13 and is received to open the lid portion 13 from the first airbag 9 and the second airbag 10 when the first airbag 9 and the second airbag 10 are deployed. It is a member that equalizes the force.
The spacer 15 is an example of a filling member in the present invention.

In the present embodiment, the second airbag 10 before deployment is disposed closer to the back surface of the lid portion 13 than the first airbag 9 before deployment, and faces the back surface and the back surface of the lid portion 13. Spacers 15 are arranged so as to fill a gap between the upper surface of the first airbag 9.
If the arrangement of the first airbag 9 and the second airbag 10 before deployment of the present embodiment is maintained and the spacer 15 is not provided, the deployment configuration of the occupant protection device 8 is stabilized as in the conventional case. There is a possibility of disappearing.

As a case where the deployment form of the occupant protection device 8 is not stable, the force received to open the lid portion 13 by the second airbag 10 which has not been provided conventionally becomes uneven depending on the portion of the lid portion 13. It is considered one of the above.
When only the first airbag 9 is provided as in the prior art, the force received to open the lid portion 13 by the first airbag 9 abutting against the back surface of the lid portion 13 during deployment thereof is as follows. Since it originates only from one airbag 9, it is basically uniform throughout the lid portion 13.
On the other hand, when the second airbag 10 is additionally provided, the second airbag 10 abuts directly on the back surface of the lid portion 13 or indirectly through the first airbag 9. Thus, it is considered that the force received to open the lid portion 13 is larger or smaller at the site where the second airbag 10 abuts than at other sites. In other words, the force received to open the lid portion 13 varies depending on the portion of the lid portion 13 and becomes non-uniform.

  In the present embodiment, as shown in FIG. 1A, the second airbag 10 is provided on the inner side in the vehicle width direction of the first airbag 9, and the first airbag 9 is a vehicle in front of the occupant M. It has a shape that expands widely in the width direction. Therefore, the second airbag 10 is disposed in a part of the first airbag 9 in the vehicle width direction. As a result, the force received to open the lid portion 13 varies along the vehicle width direction, for example, the second airbag 10 increases locally only in the vehicle width direction and relatively small otherwise. Occurs.

  When the force received for opening the lid portion 13 is in a non-uniform state, at least one of the following two problems may occur as compared with the conventional uniform state.

First, as one of the problems that may occur, for example, the deployment trajectories of the first airbag 9 and the second airbag 10 describe a trajectory in which it is difficult to achieve normal occupant protection.
Specifically, for example, the lid portion 13 is broken and opened as usual as a problem with the deployment track. However, since a portion where a large force is applied in the lid portion 13 is preferentially opened, the first airbag 9 and the first airbag 9 Compared to each part of the two airbags 10, there may be a problem that a time difference that could not occur in the prior art until the deployment in the passenger compartment is completed.

  Here, FIG. 4 shows an example of a problem related to the deployment trajectory. FIG. 4 is a schematic diagram showing a deployed form of an airbag having a protruding portion in a vehicle having an airbag to which the present invention is not applied. FIG. 4A is a schematic view of a vehicle having an airbag to which the present invention is not applied as seen from above. FIG. 4B is a schematic view when a passenger seat of a vehicle having an airbag to which the present invention is not applied is viewed from the side.

  4 (A) and 4 (B), the outer end and inner end of the first airbag in the vehicle width direction, the upper end and lower end of the first airbag in the vehicle vertical direction, and Each deployment trajectory of the most projecting portion of the second airbag 10 is indicated by a solid arrow. Further, in FIG. 4B, an ideal deployment trajectory of the second airbag 10 that can exhibit normal occupant protection performance is indicated by a dashed arrow.

  4A, the second airbag 10 disposed on the inner side in the vehicle width direction preferentially opens a part of the lid 13, and then the first airbag 9 in the vehicle width direction. It is assumed that the outer portion opens the remaining portion of the lid portion 13. In this case, as shown in FIG. 4 (A), the second airbag 10 and the inner end of the first airbag 9 in the vehicle width direction are deployed in advance, and the outer end of the first airbag 9 is Deploy with a delay. That is, a time difference is caused by the part of the first airbag 9 until the deployment is completed.

For example, when the vehicle has a full lap collision, the protection of the occupant M has been normally achieved by the airbag that is normally deployed to face the occupant M.
If the occupant protection device 8 draws the deployment track shown in FIG. 4A, the deployment may not be completed when the occupant M falls forward. Further, if the occupant M falls forward and comes into contact with the first airbag 9 in the middle of deployment, the occupant M falls down while being swung to the right by the right side portion of the first airbag 9 that is deployed late. Is also possible. In this case, the protection of the normal occupant M originally intended cannot be realized.

  4B, the second airbag 10 preferentially opens a part of the lid part 13, and then the upper side of the first airbag 9 opens the remaining part of the lid part 13. Assumes that In this case, as shown in FIG. 4B, the second airbag 10 and the lower end of the first airbag 9 in the vehicle vertical direction are deployed in advance, and the upper side of the first airbag 9 is delayed. And expand. That is, a time difference is caused by the part of the first airbag 9 until the deployment is completed. Due to this generated time difference, for example, the deployment trajectory of the second airbag 10 is largely shifted in the vehicle vertical direction as compared with an ideal deployment trajectory indicated by a broken line arrow.

  As shown in FIG. 4 (B), if the lid portion 13 is unevenly broken, the deployment trajectory deviates from the ideal state. Therefore, the deployment may not be completed when the occupant M falls toward the airbag. There is sex. Furthermore, when the occupant M falls forward during the deployment, the occupant M's face, cervical vertebra, and the like may be pushed up from below by the upper part of the rear end portion of the first airbag 9 that is delayed. In this case, the protection of the normal occupant M originally intended cannot be realized.

  As described above with reference to FIG. 4, if the force received for opening the lid portion 13 is uneven depending on the portion of the lid portion 13, the breakage of the lid portion 13 causes a time difference depending on the portion. That is, the cover part 13 does not open all at once. Basically, the occupant protection device 8 needs to be deployed particularly quickly in the direction in which the occupant M falls down. However, if the opening of the lid portion 13 is uneven, there is a possibility that the occupant protection device 8 will be deployed later in the desired direction. Occurs. That is, if the opening of the lid 13 becomes uneven, even if the lid 13 can be finally deployed in the intended shape, if the occupant M falls down while being delayed, the normal occupant M Protection may not be achieved.

Another problem that may occur is that, for example, one part of the lid 13 where the force has been exerted greatly due to the second airbag or the like and its periphery are broken open, but the other parts are not completely broken. You can mention the problem of not opening. In this case, the first airbag 9 and the second airbag 10 are not fully deployed in the passenger compartment, and the first airbag 9 and a part of the second airbag 10 are not intended on the back side of the dashboard 6. It is also conceivable that the first airbag 9 and the second airbag 10 are caught on the portion of the lid portion 13 that is not broken and the bag is torn.
That is, since the first airbag 9 and the second airbag 10 are not completely deployed, not only a collision from an oblique front as shown by a white arrow in FIG. There is a possibility that the protection performance of the occupant M cannot be sufficiently exhibited even for many collision modes.

In the embodiment shown in FIG. 3, the spacer 15 is provided on the back surface of the lid portion 13. The spacer 15 is a plate-like body that is fixedly attached to the back surface of the lid portion 13 that is one of the interior members.
In this embodiment, the filling member is a convex portion that is integrally formed with the lid portion 13 instead of the spacer 15 and protrudes from the back surface of the lid portion 13 toward the first airbag 9 and the second airbag 10. There may be.

  By arranging the spacer 15, the force for opening the lid portion 13 that acts on the back surface of the lid portion 13 from the second airbag 10 and the back surface of the lid portion 13 that acts from the first airbag 9. The force for opening the lid portion 13 is made uniform.

As shown in FIG. 3, since the second airbag 10 is disposed close to the back surface of the lid portion 13, so as to be close to the first airbag 9 disposed away from the back surface of the lid portion 13. Spacers 15 are arranged. Thus, when the first airbag 9 and the second airbag 10 are inflated, the second airbag 10 directly contacts the back surface of the lid portion 13, and the first airbag 9 is the contact that is the maximum protruding portion of the spacer 15. It will contact the part 151. Therefore, the lid 13 directly receives a force for opening from the second airbag 10 and indirectly receives a force for opening from the first airbag 9 via the spacer 15. As described above, in the embodiment shown in FIG. 3, by disposing the spacer 15, the force that the lid portion 13 receives to break and open acts uniformly on any portion of the lid portion 13. .
As a result, the lid portion 13 on which the force is applied uniformly is broken at the groove portion 131 by the first airbag 9 and the second airbag 10 and is opened at once. Thereby, as mentioned above, the malfunction which may arise by the nonuniformity of the opening force does not occur.

  In the present embodiment, the magnitude of the force for opening the interior member that acts on the interior member from the first airbag and the second airbag is, for example, the folding of the first airbag and the second airbag. If the form, the gas press-fitting form, etc. are changed, it can be adjusted appropriately.

Furthermore, in this embodiment, if each of the first airbag and the second airbag can arrange the timing for opening the interior member, the force for opening the interior member may be made uniform.
In order to align the timing when the first airbag and the second airbag each open the interior member, the filling member in this embodiment such as the spacer 15 shown in FIG. 3 is suitable.

The spacer 15 will be described in detail as to when the interior member opens. The spacer 15 has a time difference between when the second airbag 10 opens the lid 13 and when only the first airbag 9 opens the lid 13 through the spacer 15. Can be reduced. This is because the spacer 15 is in contact with the contact portion 151 of the spacer 15 when the second airbag 10 comes into contact with the back surface of the lid portion 13 after the gas injection is started. This is because the time difference from the time can be reduced.
Thereby, the lid portion 13 is uniformly broken without deviation depending on the portion. Therefore, in the embodiment shown in FIG. 3, it is possible to realize the form of breaking the lid portion 13 as in the case where only the first airbag 9 is provided as in the prior art, and the airbag can be stably deployed. Become.

  In the present embodiment, the filling member need not completely eliminate the time difference between the first airbag 9 and the second airbag 10 when the lid 13 is opened, and does not affect the stable deployment of the airbag. It only has to be as small as possible.

  The size and arrangement of the spacer 15 are such that the shortest distance between the leading contact portion 81 of the second airbag 10 and the back surface of the lid portion 13 and the maximum protrusion of the trailing contact portion 82 of the first airbag 9 and the spacer 15. The shortest distance with the contact part 151 which is a site | part is determined so that it may become the same or substantially the same.

Here, the leading contact portion 81 and the trailing contact portion 82 will be described.
First, when the spacer 15 is not provided in the embodiment shown in FIG. 3, when the gas is pressed into the first airbag 9 and the second airbag 10 from the inflator 12, the leading contact portion 81 is the most. It is a part that comes into contact with the lid part 13 at an early stage, and the trailing contact part 82 is a part that comes into contact with the lid part 13 later than the preceding contact part 81.
When the first airbag 9 and the second airbag 10 are folded, the second airbag 10 is closer to the lid portion 13 than the first airbag 9 in the embodiment shown in FIG. A portion of the second airbag 10 facing the back surface of the lid portion 13 is the preceding contact portion 81. Further, the portion of the first airbag 9 facing the back surface of the lid portion 13 becomes the trailing contact portion 82.

In the present embodiment, it is assumed that the speed at which the second airbag 10 is expanded toward the lid portion 13 and the speed at which the first airbag 9 is expanded toward the spacer 15 are the same. The shortest distance between the 15 contact portions 151 and the subsequent contact portion 82 is set.
When this embodiment is applied to an existing airbag, the speed difference between the first airbag and the second airbag when inflating toward the interior member is the shape and capacity of the first airbag and the second airbag. It changes according to the arrangement of the first airbag and the second airbag in the folded state. Therefore, it is preferable that the size and arrangement of the filling member such as the convex portion or the spacer be determined in view of the properties of each bag.

In the present embodiment, various portions of the first airbag and the second airbag can serve as the leading contact portion and the trailing contact portion according to the folded form of the first airbag and the second airbag.
Actually, for example, when the second airbag and the first airbag are arranged substantially flush with each other in a folded state and there is no difference in the distance from the interior member, or when the second airbag is disposed in the first airbag. The case where the bag is wrapped and disposed, and the first airbag is closer to the interior member is considered.
Even in these cases, as compared with the case where only the first airbag is provided as in the prior art, the expansion configuration changes due to the provision of the second airbag. For example, while only the first airbag has been inflated in the past, the second airbag will also expand at the same time. It is conceivable that the deployment direction and deployment posture of the occupant protection device 8 are biased toward the deployment direction of the second airbag.

Therefore, as long as the second airbag communicating with the first airbag is provided as in the present embodiment, the leading contact portion and the trailing contact portion are generated in a part of the first airbag and the second airbag. It will be.
In addition, it is considered that the unbalance of the deployment is particularly large compared to the inflated form in the case where only the first airbag is provided. For example, at least a part of the second airbag is folded with the first airbag in the folded state. This is a case where the second airbag is disposed so as to overlap with a part of the first airbag when it is disposed between the lid portion and the inside of the accommodating portion when viewed from the lid portion side. In this case, when the filling member such as the spacer 15 is not provided, the first airbag and the second airbag try to deploy independently from each other. large.

For example, it is conceivable that the time when the first airbag opens the interior member is earlier than the time when the second airbag opens the interior member. In this case, contrary to the embodiment shown in FIG. 3, a part of the first airbag is a leading contact part and a part of the second airbag is a trailing contact part. Even in this case, the filling member such as the spacer 15 may be provided facing the trailing contact portion of the second airbag.
Further, for example, a case where the second airbag is folded while being wrapped by the first airbag is also conceivable. In this case, the second airbag does not directly contact the back surface of the interior member when each airbag is deployed. Therefore, a part of the first airbag that is greatly inflated by adding the inflated portion of the second airbag serves as a leading contact portion, and a portion that contacts the interior member by the expansion of only the first airbag is a trailing contact portion. Become. Even in this case, the filling member such as the spacer 15 may be provided facing the trailing contact portion of the first airbag.

  In this embodiment, after changing variously the capacity | capacitance and shape of each bag body, a folding form, a gas press-fitting form, etc., which site | part of a 1st airbag and a 2nd airbag is a leading contact part and a back-and-forth By preliminarily identifying whether or not the contact portion is to be obtained by a test or the like, the arrangement or the like of the filling member can be easily determined.

  In the present embodiment, the filling member such as the convex portion or the spacer is fixedly attached to the back surface of the interior member, thereby maintaining the state where the filling member is fixed to the interior member during and after the airbag is deployed. Therefore, the filling member does not hit the occupant. That is, it is preferable because it does not interfere with passenger protection during and after deployment of the airbag.

  Although the passenger seat airbag is illustrated in the embodiment shown in FIGS. 1 to 3, the present embodiment can be applied to an airbag for a driver's seat and other airbags provided in various parts.

  As mentioned above, although embodiment which applied the invention made | formed by this inventor was described, this invention is not limited by the description and drawing which make a part of indication of this invention by this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
