Description

Technical Field

[0001] This invention relates to a side airbag device. More specifically, this invention relates to a side airbag device that inflates and deploys to the side of a passenger in the event of a side collision with a vehicle such as an automobile. Background Technology

[0002] A side airbag device is known to prevent passengers from moving inward in the width direction of the vehicle and coming into contact with adjacent passengers during a side collision.

[0003] For example, Patent Document 1 discloses a passenger restraint system for vehicles, the purpose of which is to effectively suppress the movement of airbags inward in the vehicle width direction when restraining passengers. In the above-mentioned passenger restraint system for vehicles, by having the sub-airbags abut against the control box, the movement of the main airbag inward in the vehicle width direction when blocking the passenger is suppressed, and as a result, the movement of the passenger is suppressed.

[0004] In addition, Patent Document 2 discloses an airbag designed to keep passengers in the correct position during a side collision of a vehicle.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2014-108740

[0008] Patent Document 2: International Publication No. 2019 / 228898

[0009] However, in the passenger restraint system for vehicles described in Patent Document 1, because the sub-airbag is brought into contact with the corner of the control box, the main airbag and the sub-airbag rotate around the corner of the control box until the upper surface of the control box and the sub-airbag come into contact. This results in a delay before the passenger stops moving inward in the vehicle width direction, and the amount of passenger movement increases.

[0010] Furthermore, in existing side airbag devices, when the airbag swings due to rapid inflation, its deployment position relative to the corner of the control box is prone to shift, making it difficult to promptly suppress passenger movement towards the inside of the vehicle in the width direction. For example, in the airbag described in Patent Document 2, there is room for improvement in addressing the aforementioned problem. Summary of the Invention

[0011] The present invention was made in view of the above circumstances, and its object is to provide a side airbag device that can promptly suppress the movement of passengers inward in the width direction of the vehicle.

[0012] An embodiment of the present invention provides a side airbag device that inflates above a control box located inside the vehicle width direction of a vehicle seat and inflates to the side of a passenger sitting in the vehicle seat. The airbag includes: a gas generator that generates gas; and a bag-shaped airbag that inflates with the gas when the gas generator is activated to protect the side of the passenger. The airbag has: a main body protection portion that inflates to the side of the passenger's main body; a support portion located on the control box side of the main body protection portion and pressed against the upper surface of the control box during inflating; and a lumbar protection portion that inflates between the passenger's waist and the side of the control box. The support portion and the lumbar protection portion are formed by continuous air chambers. The gas generator, when viewed from the side of the vehicle, spans above and below the support portion. The airbag is fixed to the side of the vehicle seat via the gas generator.

[0013] According to the present invention, a side airbag device that can promptly suppress the movement of passengers inward in the vehicle width direction can be provided. Attached Figure Description

[0046] The side airbag device according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0047] Unless otherwise specified, all descriptions of directions in this manual are based on the vehicle. For example, "front" indicates the direction forward of the vehicle, "rear" indicates the direction backward of the vehicle, "above" indicates the direction above the vehicle, and "side" indicates the inward direction in the width direction of the vehicle. Furthermore, arrows FR (forward), UP (upward), IN (inward), and OUT (outward) are appropriately shown in the figures to indicate the direction forward of the vehicle, the direction above the vehicle, the inward direction in the width direction of the vehicle, and the direction outside the width direction of the vehicle. Additionally, the components housed inside the vehicle seat are illustrated in perspective of the vehicle seat.

[0048] (Before expansion)

[0049] Figure 1 This is a schematic diagram showing the state of the side airbag device of the embodiment as viewed from the side before the airbag inflates and deploys. Figure 2 This is a schematic diagram showing the state of the side airbag device of the embodiment as viewed from the front before the airbag inflates and deploys.

[0050] like Figure 1 and Figure 2 As shown, the side airbag device 1 is fixed to the side of the seat back (backrest) 31 of the vehicle seat 30 (the side inside the vehicle width direction).

[0051] As a vehicle seat 30, for example, it is the driver's seat, the front passenger seat, etc.

[0052] The side airbag device 1 has a gas generator 10 and an airbag 20.

[0053] The gas generator 10 is located inside the airbag 20. More specifically, the entire gas generator 10 is located inside the airbag 20. The gas generator 10 is a cylindrical gas generating device and is arranged along the extending direction (height direction) of the seat back 31. A pair of bolts 10A and 10B protrude from the upper and lower parts of the gas generator 10, respectively, and pass through the airbag 20. The gas generator 10 is fixed to the side of the seat back 31 (e.g., the side frame) by the pair of bolts 10A and 10B as described above.

[0054] The gas generator 10 activates upon a side impact of the vehicle. Specifically, firstly, if the vehicle's collision detection sensors detect a side impact, the ECU (Electronic Control Unit) processes the signals from the collision detection sensors to determine the collision level. If the determined collision level matches the conditions for inflating the airbag 20, the gas generator 10 is ignited to produce gas through a chemical reaction caused by combustion. As a result, the gas generated by the gas generator 10 is introduced into the airbag 20.

[0055] There is no particular limitation on the type of gas generator 10. For example, it can include a pyrotechnic gas generator that uses gas generated by burning a gas generating agent, a gas storage gas generator that uses compressed gas, and a mixed gas generator that uses a mixture of gas generated by burning a gas generating agent and compressed gas.

[0056] The airbag 20 has a built-in gas generator 10. Before inflating and deploying, the airbag 20 is fixed in a folded state to the side of the vehicle seat 30 via the gas generator 10, which is the side of the seat back 31. It is covered and stored together with the cushioning pad by the surface of the seat back 31.

[0057] Figure 3 It means Figure 2 A three-dimensional schematic diagram illustrating an example of the deployed state of an airbag. (See diagram below.) Figure 3 As shown, the airbag 20 is bag-shaped. The airbag 20 is formed into a three-dimensional bag shape by joining the outer peripheries of multiple base fabric pieces together. Specifically, in Figure 3 In the airbag 20 shown, the outer peripheries of the passenger-side base fabric 20A disposed inside the vehicle width direction, the passenger-side base fabric 20B disposed outside the vehicle width direction, the intermediate base fabric 20C disposed on the vehicle front direction side and the vehicle rear direction side, and the base fabric 20D disposed on the vehicle top direction side and the vehicle bottom direction side are joined together. (This is in conjunction with the description below.) Figure 6 and Figure 8 It can be seen that the base fabric 20A on the passenger side is bent in a manner that runs along the upper surface and side of the control box 60. In addition, in the state viewed from the front and rear direction of the vehicle, the intermediate base fabric 20C has a shape that runs along the upper surface and side of the control box 60.

[0058] In the airbag 20, preferably, the base fabric disposed on the front side of the vehicle and the base fabric disposed on the rear side of the vehicle have a shape along the upper surface and side of the control box 60 when viewed from the front-rear direction of the vehicle. Figure 4 It means Figure 2 The deployment state of the airbags in the middle and Figure 3 A different example of a three-dimensional diagram. In Figure 4 In the airbag 20 shown, the intermediate base fabric 20C disposed on the front and rear sides of the vehicle has a shape along the upper surface and side of the control box 60 when viewed from the front-rear direction. Figure 4 The airbag 20 shown is... Figure 3 Compared to the airbag 20 shown, the capacity of the airbag 20 can be reduced.

[0059] The passenger-side base fabric 20B of the airbag 20 is provided with a gas generator insertion port 20P for inserting the gas generator 10 into the airbag 20. Figure 3 and Figure 4 The illustration shows a case where the gas generator insertion port 20P is slit-shaped. Since bolt holes are provided in the vertical direction of the gas generator insertion port 20P, after the entire gas generator 10 is inserted into the airbag 20 through the gas generator insertion port 20P, a pair of bolts 10A and 10B protrude outwards from the bolt holes of the airbag 20. Then, the airbag 20 in its folded state is fixed to the side of the seat back 31 via the gas generator 10, so that the gas generator insertion port 20P is opposite to the seat back 31. Therefore, when the airbag 20 inflates and deploys, gas leakage from the airbag 20 is prevented because the gas generator insertion port 20P is sealed by the seat back 31.

[0060] The base fabric constituting the airbag 20 can be, for example, a fabric woven from yarns of nylon 66, polyethylene terephthalate, etc. To improve heat resistance and airtightness, the surface of the base fabric can also be covered with inorganic materials such as silicon.

[0061] Methods for joining the base fabric include, for example, sewing, bonding, welding, or combinations thereof.

[0062] In this embodiment, the World-SID (World Side Impact Dummy) 40 is seated in the vehicle seat 30. Currently, the seating posture of the World-SID dummy 40 is determined using the side impact test method (ECE R95) adopted in Japan and Europe, or the side impact test method (FMVSS214) adopted in the United States. The position and size of the airbag 20 during inflated deployment (hereinafter also referred to as "during deployment") are determined according to... Figure 1 The positions of the main body 41, waist 42, head 43, and arms 44 of the internationally standardized side-impact dummy 40 are set as shown. Hereinafter, the internationally standardized side-impact dummy 40 will be referred to as "passenger 40".

[0063] As for the vehicle side wall 50, it can be any part of the vehicle body located on the outside of the passenger 40 in the vehicle width direction (opposite to the control box 60) where the passenger sits on the vehicle seat 30, without any special limitation, and is a general term for side doors, pillars, side windows, etc.

[0064] The control box 60 is located inside the vehicle seat 30 in the vehicle width direction. For example, the control box 60 is located in the center of the vehicle width direction between the driver's seat and the front passenger seat. The control box 60 can also function as an armrest (hand rest) of the arm 44 that supports the passenger 40 in the vehicle width direction.

[0065] (Initial stage of passenger restraint)

[0066] Figure 5 This is a schematic diagram showing the state of the side airbag device of the embodiment as viewed from the side during the initial stage of passenger restraint by the airbag. Figure 6 This is a schematic diagram showing the state of the side airbag device of the embodiment as viewed from the front during the initial stage of passenger restraint by the airbag.

[0067] When a vehicle collides with an obstacle (e.g., another vehicle), specifically, when the vehicle sidewall opposite the vehicle sidewall 50 (the part of the vehicle body located outside the passenger seat in the vehicle width direction when the vehicle seat 30 is the driver's seat) collides with the obstacle, causing the gas generator 10 to activate, the gas generated in the gas generator 10 is introduced into the airbag 20, and the airbag 20 inflates while releasing the aforementioned fold. When the surface of the seat back 31 ruptures due to the force exerted by the inflated airbag 20, as... Figure 5 and Figure 6 As shown, the airbag 20 inflates above the control box 60 and to the side of the passenger 40 seated in the vehicle seat 30, thereby protecting the side of the passenger 40. The airbag 20 that inflates and deploys as described above is also referred to as a distal side airbag.

[0068] In the event of a side impact, the passenger 40, seated in the vehicle seat 30, tilts inwards in the vehicle width direction, centered on their waist 42. Meanwhile, during the side impact, the airbag 20 inflates, forming a main protection section 21, a support section 22, and a lumbar protection section 23. When the airbag 20 inflates, the main protection section 21 expands and extends to the side of the passenger 40's body 41 and contacts the body 41. The support section 22 is located on the side of the main protection section 21 near the control box 60 and expands in contact with the upper surface of the control box 60. The lumbar protection section 23 expands and extends between the passenger 40's waist 42 and the side of the control box 60.

[0069] When expanded and deployed, the support portion 22 and the waist protection portion 23 preferably extend along the upper surface and sides of the control box 60 when viewed from the rear-facing direction of the vehicle. For example, in Figure 6 In the airbag 20 shown, since the intermediate base fabric 20C has a shape along the upper surface and side of the control box 60 when viewed from the front-rear direction of the vehicle, the support portion 22 expands and deploys while contacting the upper surface of the control box 60. Furthermore, the waist protection portion 23 expands and deploys while contacting the side of the control box 60 when viewed from the front-rear direction of the vehicle.

[0070] The support portion 22 and the lumbar protection portion 23 are composed of continuous air chambers. The fact that each part of the airbag 20 (here, the support portion 22 and the lumbar protection portion 23) is composed of continuous air chambers means that there are no partition walls separating the air chambers at the boundaries of each part of the airbag 20, and it is not formed by multiple bags. Because the support portion 22 and the lumbar protection portion 23 are composed of continuous air chambers, compared to, for example, the case where the lumbar protection portion 23 is provided by joining bag-shaped sub-airbags, it is possible to prevent twisting or other movements between the support portion 22 and the lumbar protection portion 23. As a result, the airbag 20 can rapidly inflate and deploy at the support portion 22 and the lumbar protection portion 23, thereby restraining the passenger 40 as early as possible.

[0071] (Later stages of passenger restraint)

[0072] Figure 7 This is a schematic diagram showing the state of the side airbag device of the embodiment as viewed from the side after the passenger is restrained by the airbag. Figure 8 This is a schematic diagram showing the state of the side airbag device of the embodiment as viewed from the front during the later stage of passenger restraint by the airbag. Figure 9 Viewed from above near the gas generator Figure 7 and Figure 8 A schematic diagram of the cross-section of the side airbag device.

[0073] When passenger 40 moves further inward in the width direction of the vehicle, such as Figure 8 As shown, the lumbar support 23 is flattened between the waist 42 of the passenger 40 and the side of the control box 60. Because the lumbar support 23 is flattened, the internal pressure of the support 22, which is formed by air chambers continuous with the lumbar support 23, increases. Since the support 22 and the lumbar support 23 are formed by continuous air chambers, the flattening of the lumbar support 23 easily causes the internal pressure of the support 22 to rise.

[0074] On the other hand, the main body protection section 21 tilts inward in the vehicle width direction due to contact with the main body 41 of the passenger 40, which is tilted inward in the vehicle width direction. When the main body protection section 21 tilts inward in the vehicle width direction, the support section 22 is immediately pressed against the upper surface of the control box 60, thus generating a reaction force from the upper surface of the control box 60. At this time, as described above, the reaction force from the upper surface of the control box 60 increases due to the increase in internal pressure of the support section 22. Therefore, when the aforementioned larger reaction force is applied to the main body protection section 21 via the support section 22, the force that wants to return the main body protection section 21 to the initial position of passenger restraint (outer side in the vehicle width direction) plays a greater role, and as a result, the movement of the passenger 40 inward in the vehicle width direction is promptly suppressed.

[0075] Furthermore, as described above, since the support portion 22 and the lumbar protection portion 23 expand and deploy along the upper surface and side of the control box 60 when viewed from the front-rear direction of the vehicle, the airbag 20 will not rotate around the corner of the control box 60, thus stabilizing the deployment of the airbag 20. This stabilization of the airbag 20 deployment also helps to promptly suppress the passenger 40 from moving inward in the width direction of the vehicle.

[0076] The portions of the support section 22 and the waist protection section 23 that face the upper surface and sides of the control box 60 when expanded are preferably made of a continuous single base fabric. For example, in Figure 3 and Figure 4 In the airbag 20 shown, the portions of the support portion 22 and the lumbar protection portion 23 that face the upper surface and side surface of the control box 60 during expansion are made of a continuous single base fabric 20A. By making these portions of the support portion 22 and the lumbar protection portion 23 that face the upper surface and side surface of the control box 60 during expansion a continuous single base fabric, the expansion diameter of the airbag 20 at these portions is increased, allowing it to expand and expand in a circular manner. Therefore, the reaction force from the upper surface and side surface of the control box 60 during expansion is further increased, resulting in a further increase in the restraining force of the airbag 20 (main body protection portion 21) that prevents the passenger 40 from moving inward in the vehicle width direction. Furthermore, by expanding and expanding the airbag 20 as described above, the support portion 22 and the lumbar protection portion 23 can come into contact with the control box 60 as quickly as possible.

[0077] Preferably, when viewed from the front-rear direction of the vehicle, the support portion 22 is pressed against more than half of the upper surface of the control box 60 during expansion and unfolding. More preferably, as... Figure 8The support 22 is pressed against the entire upper surface of the control box 60. By pressing more than half of the upper surface of the control box 60 when it expands, the reaction force from the upper surface of the control box 60 can be further increased. As a result, the restraining force of the airbag 20 (main body protection part 21) that prevents the passenger 40 from moving inward in the vehicle width direction is further increased.

[0078] Preferably, the main body protection part 21, the support part 22, and the waist protection part 23 are as follows: Figure 8 As shown, it consists of continuous air chambers, located between the upper end of the main protective part 21 and the inner end of the support part 22 in the vehicle width direction, as... Figure 8 As shown, when viewed from the front-rear direction of the vehicle, there is no concave portion when the airbag is inflated. Because the airbag 20 has the structure described above, it is prevented from bending between the main protective portion 22 and the support portion 22 when it blocks the passenger 40. As a result, the airbag 20 can stably block the passenger 40.

[0079] It can also be like Figure 8 As shown, the airbag 20 also has a head protection section 24. The head protection section 24 is located above the main protection section 21 and protects the head 43 of the passenger 40. Because the airbag 20 has the head protection section 24, it can block the passenger 40 as a whole. As a result, the airbag 20 can effectively suppress the passenger 40 from moving inward in the vehicle width direction.

[0080] The gas generator 10 is built into the airbag 20, such as Figure 8 As shown, when viewed from the side of the vehicle, the airbag 20 extends over and under the support 22, and more specifically, over the main body protection 21 and the waist protection 23. Furthermore, a pair of bolts 10A and 10B of the gas generator 10 are located above and below the support 22, respectively. Therefore, when the airbag 20 inflates and deploys due to the gas generated by the gas generator 10, the location of gas generation is relatively close to the support 22, thus maintaining a high air pressure near the support 22 during the airbag 20's inflating and deploying. This ensures the independence of the airbag 20 through the support 22. Therefore, even if the airbag 20 swings due to rapid inflating and deploying, the main body protection 21, the support 22, and the waist protection 23 are unlikely to swing. As a result, the airbag 20's inflating and deploying position relative to the corner of the control box 60 is unlikely to shift, and the airbag 20's deployment action is stable, thus effectively suppressing the passenger 40 from moving inward in the vehicle width direction.

[0081] In addition, such as Figure 9As shown, the airbag 20 is fixed to the side of the vehicle seat 30 via the gas generator 10, specifically to the side of the seat back 31. By fixing the gas generator 10 and the airbag 20 as described above, the main protection part 21, the support part 22, and the lumbar protection part 23 are also fixed to the side of the vehicle seat 30 via the gas generator 10, specifically to the side of the seat back 31. This further restricts the swaying of the support part 22 near the fixed gas generator 10 when the airbag 20 inflates. As a result, the inflated position of the airbag 20 relative to the corner of the control box 60 is less likely to shift, and the deployment of the airbag 20 is stable, thus effectively suppressing the passenger 40 from moving inward in the vehicle width direction.

[0082] On the other hand, when the airbag 20 blocks the passenger 40 moving inward in the width direction of the vehicle, the lumbar support 23, which expands between the passenger 40's waist 42 and the side of the control box 60, may be pulled out from its position. In contrast, by fixing the lumbar support 23 to the side of the vehicle seat 30 as described above (here, to the side of the seat back 31), the lumbar support 23 is difficult to pull out, and therefore the lumbar support 23 can stably protect the passenger 40's waist 42.

[0083] The airbag 20, which expands due to the gas generated in the gas generator 10, inflates in a way that makes it as round as possible due to the internal pressure. Therefore, within the airbag 20, as... Figure 9 As shown, a central base fabric 20C is present on the front side of the vehicle, so that the position with the greatest thickness in the vehicle width direction when inflated and deployed is located on the front side of the vehicle. Therefore, the passenger 40 can be protected more stably by surrounding the passenger 40 between the position with the greatest thickness in the vehicle width direction of the airbag 20 and the seat back 31.

[0084] As for the other components of the side airbag device 1, the same components as those of existing known side airbag devices can be appropriately adopted.

[0085] This invention is not limited to the contents described in the above embodiments. Without departing from the spirit of this invention, the structures described in the embodiments may be appropriately deleted, added, modified, or combined.

[0086] For example, although the above embodiment describes the case where the gas generator 10 is activated when an obstacle collides with the vehicle side wall 50, which is opposite to the vehicle side wall 50 in the vehicle width direction, it is also possible for the gas generator 10 to be activated when an obstacle collides with the vehicle side wall 50. In this case, after the passenger 40 is restrained by the side airbag that expands and deploys on the outer side of the passenger 40 in the vehicle width direction, and then moves inward in the vehicle width direction due to swaying or the like, the airbag 20 can promptly restrain the passenger 40.
