Description

Technical Field

[0001] This disclosure relates to passenger airbags installed in vehicle seats. Background Technology

[0002] Typically, passenger airbags are installed in the cockpit module to protect passengers seated in the event of a collision. In the event of a collision, the passenger airbag deploys from the cockpit module to the passenger seat.

[0003] Recently, regulations regarding tilting collisions, in addition to frontal collisions, have been strengthened in cases involving vehicles, obstacles, or people. Therefore, recent passenger airbags not only include a main panel that protrudes from the cockpit module and deploys towards the passenger, but also a protruding panel that projects from the main panel and contacts the side of the passenger's head when the airbag deploys. Thus, in a tilting collision, the protruding panel can prevent head injury even when the passenger's head rotates.

[0004] In this configuration, the protruding panel may have a shape that connects to at least one of the two sides of the main panel. Therefore, when gas is generated from the inflator connected to the main panel, the gas flows from the main panel to the protruding panel, causing the protruding panel to inflate.

[0005] However, a potential problem exists: in the event of a collision and when a passenger's head contacts the protruding panel, the gas contained within it flows from the protruding panel to the main panel. Then, as the passenger's head contacts the protruding panel, the panel's expansion decreases rapidly, potentially reducing the support force the panel should provide to the passenger's head.

[0061] In the following description of the passenger airbag with reference to the accompanying drawings, the same or corresponding parts in all the drawings will be indicated by the same reference numerals, and redundant descriptions will be omitted.

[0062] This disclosure aims to provide an improved passenger airbag to prevent the rapid decrease in the amount of inflation of the protruding panel when the passenger's head comes into contact with the panel.

[0063] Figure 1 This is a perspective view showing a passenger airbag according to one embodiment of the present disclosure. Figure 2 This is a view showing the partition wall. Figure 3 This is a view showing another example of the inlet hole of the partition wall. Figure 4 This is a schematic side view showing the interior of the passenger airbag.

[0064] refer to Figure 1 and Figure 4 According to one embodiment of this disclosure, the passenger airbag 1 can be disposed in the driver's cabin module (not shown) of a vehicle. More specifically, when the passenger airbag 1 is disposed in the driver's cabin module, the passenger airbag 1 can deploy toward the passenger seat, which is the seat disposed in the vehicle adjacent to the driver's seat. Therefore, in the event of a collision, the passenger airbag 1 can protect the front of the upper body, including the face, shoulders, and chest of the passenger sitting in the passenger seat. The passenger airbag 1 may include a deployment portion and a partition wall 300, the deployment portion including a first protruding panel 100 and a second protruding panel 200.

[0065] The deployable section can be housed in a folded state within the cockpit module. The deployable section can be connected to an inflator. The deployable section may include a first protruding panel 100 and a second protruding panel 200.

[0066] The first protruding panel 100 can be connected to and support the second protruding panel 200. Additionally, the first protruding panel 100 can be connected to an inflator (not shown) for generating gas and inflated by gas generated from the inflator. For this purpose, the first protruding panel 100 can have a hollow shape, and two components, such as fabric, can contact each other, with the edges of the two components joined to form the first protruding panel 100.

[0067] The first protruding panel 100 may protrude toward the passenger seat. More specifically, with the first protruding panel 100 disposed in the cockpit module, the first protruding panel 100 may protrude to penetrate the cockpit module and unfold toward the passenger seat. Here, a vent may be provided in the first protruding panel 100. The vent may be a hole for guiding gas contained in the first protruding panel 100 to the outside of the first protruding panel 100 to prevent the first protruding panel 100 from over-unfolding.

[0068] The second protruding panel 200 may be disposed on at least one of the two sides of the first protruding panel 100. Similar to the first protruding panel 100, the second protruding panel 200 may contain gas generated from an inflator. For this purpose, the second protruding panel 200 may have a hollow shape, allowing two components, such as fabric, to contact each other, and then the edges of the two components can be joined to form the second protruding panel 200. In this case, the second protruding panel 200 may be integrally formed with the first protruding panel 100. That is, the second protruding panel 200 may have a shape that protrudes from the first protruding panel 100.

[0069] The second protruding panel 200 may include an inlet portion 220 formed at a boundary that contacts the first protruding panel 100. The inlet portion 220 may connect the first protruding panel 100 to the second protruding panel 200 and may also serve as a channel for guiding gas contained in the first protruding panel 100 to the second protruding panel 200.

[0070] Figure 5 It is along Figure 1 The sectional view taken by line A-A. Figure 6 It is along Figure 1 The sectional view taken by line B-B.

[0071] Reference Figure 2 , Figures 4 to 6 A partition wall 300 may be disposed in the unfolded portion. The partition wall 300 may cover the inlet portion 220 of the second protruding panel 200. The partition wall 300 may adjust the inflow rate of gas flowing from the first protruding panel 100 toward the second protruding panel 200, such that the second protruding panel 200 unfolds after the first protruding panel 100 unfolds. The partition wall 300 may include a main body portion 320 and an inlet hole 340.

[0072] The main body 320 may form the exterior of the partition wall 300. The main body 320 may support the connecting portion. The main body 320 may be provided at the inlet portion 220 formed in the second protruding panel 200. Therefore, the main body 320 may cover a portion of the inlet portion 220 of the second protruding panel 200 to prevent gas flowing in the first protruding panel 100 from being introduced into the second protruding panel 200.

[0073] An inlet hole 340 may be formed in the main body portion 320. More specifically, the inlet hole 340 may be a hole that passes through a portion of the main body portion 320 to connect the internal space of the first protruding panel 100 to the internal space of the second protruding panel 200. The inlet hole 340 may be provided in the central portion of the main body portion 320, but is not limited thereto. When the inlet portion 220 of the second protruding panel 200 is covered, the inlet hole 340 may communicate with the inlet portion 220 of the second protruding panel 200. Additionally, as... Figure 2 As shown, the inlet hole 340 may have a circular shape, but is not limited to this.

[0074] Additionally, refer to Figure 3 Multiple inlet holes 340 can be formed in the main body 320. In this case, the inlet holes 340 can be arranged separately from each other in the height direction, which is based on... Figure 3 The direction from the upper part to the lower part of the main body 320. In addition, although not shown in the figure, the plurality of inlet holes 340 formed in the main body 320 can be arranged separately from each other in the width direction, and can be arranged separately from each other in a direction inclined relative to the height direction or the width direction between the height direction and the width direction, wherein the width direction is a direction perpendicular to the height direction.

[0075] Reference Figure 6 With the partition wall 300 covering the entrance portion 220 of the second protruding panel 200, the two side ends of the main body 320 of the partition wall 300 can be connected to the boundary between the first protruding panel 100 and the second protruding panel 200. Additionally, referring to... Figure 2 , Figure 4 and Figure 5 The first width W1 of the main body 320 of the partition wall 300 may be greater than the second width W2 of the entrance portion 220 of the second protruding panel 200. For example... Figure 4 and Figure 5 As shown, due to the characteristics of the partition wall 300, the partition wall 300 provided in the unfolded portion can be configured to bend toward the first protruding panel 100 while the partition wall 300 covers the entrance portion 220 of the second protruding panel 200. Furthermore, as... Figure 6 As shown, when viewed from above, the partition wall 300 can cover the entire area of ​​the entrance portion 220 of the second protruding panel 200.

[0076] This is to reduce the area of ​​the inlet portion 220 of the second protruding panel 200 by the partition wall 300, thereby reducing the amount of gas flowing from the first protruding panel 100 toward the second protruding panel 200, and also allowing gas to flow through the gap between the first protruding panel 100 and the partition wall 300, which is bent toward the first protruding panel 100. Therefore, compared to a conventional airbag structure without the partition wall 300, there may be a time delay in the introduction of gas into the second protruding panel 200. Thus, it is possible to prevent the second protruding panel 200 from deploying earlier than the first protruding panel 100.

[0077] More specifically, when gas is generated from the inflator, the gas flows from the first protruding panel 100 toward the second protruding panel 200 in the direction of gas supply. In this case, when the partition wall 300 is not present, it is possible that only the second protruding panel 200 may be fully inflated by the gas flow toward the second protruding panel 200 while the first protruding panel 100 is not fully inflated.

[0078] This could lead to a problem where the passenger airbag 1 cannot reach the passenger's body in the event of a collision. Therefore, a partition wall 300 can be provided in the deployed portion to prevent this problem. That is, since the area of ​​the inlet portion 220 of the second protruding panel 200 is reduced due to the partition wall 300, the amount of gas flowing from the first protruding panel 100 to the second protruding panel 200 can be less than the amount of gas in the inlet portion 220 of the second protruding panel 200 when it is fully open. Therefore, the second protruding panel 200 can be deployed after the first protruding panel 100 is fully deployed.

[0079] As described above, since the passenger airbag 1 according to one embodiment of the present disclosure has a structure in which the second protruding panel 200 expands after the first protruding panel 100 has fully expanded by the partition wall 300, the deployed portion can reach the body part of the passenger sitting in the passenger seat within the time range calculated during the manufacturing process in the event of a collision. Therefore, in the event of a collision, additional injuries caused by delayed airbag deployment can be prevented.

[0080] In addition, according to one embodiment of the present disclosure, the passenger airbag 1 may have a structure in which a partition wall 300 is disposed in the deployed portion such that gas flows only through the inlet hole 340 of the partition wall 300 and the gap between the first protruding panel 100 and the partition wall 300 which is configured to bend toward the first protruding panel 100.

[0081] This means that, with gas introduced into the second protruding panel 200, the amount of gas flowing from the second protruding panel 200 to the first protruding panel 100 is less than the amount of gas in the conventional case without the partition wall 300. Therefore, when the passenger airbag 1 deploys, the tension of the second protruding panel 200 can be maintained. Thus, when the second protruding panel 200 contacts the passenger's head, the force of the contact between the second protruding panel 200 and the passenger's head can be prevented from pushing the second protruding panel 200 out.

[0082] Figure 7 This is a view showing multiple second protruding panels and multiple partition walls.

[0083] Reference Figure 7 The second protruding panel 200 may be disposed on each of the two sides of the first protruding panel 100. That is, multiple second protruding panels 200 may be provided. Therefore, multiple partition walls 300 may also be provided to cover the inlet portion 220 of each second protruding panel 200. As described above, in the passenger airbag 1 of this disclosure, the number of partition walls 300 may be configured to correspond to the number of second protruding panels 200 protruding from the first protruding panel 100 to maintain the inflation amount of the multiple second protruding panels 200.

[0084] The guide panel 400 will be described below.

[0085] Figure 8 This is a side view showing the guide panel installed in the main body of the partition wall, and Figure 9 This is a plan view showing the guide panel installed in the main body of the partition wall. Figure 10 This shows how to add a guide panel. Figure 6 A view of the state of the cross-section, and Figure 11 This is a view showing the curved guide panel.

[0086] Reference Figures 8 to 10 According to one embodiment of the present disclosure, the passenger airbag 1 may further include a guide panel 400. The guide panel 400 may be connected to the partition wall 300 and may be connected to the interior of the first protruding panel 100 and the interior of the second protruding panel 200. The guide panel 400 may have a hollow cylindrical shape.

[0087] The guide panel 400 may include an inlet end 420 and an outlet end 440. The inlet end 420 is connected to the interior of the first protruding panel 100 via a partition wall 300, and the outlet end 440 is connected to the interior of the second protruding panel 200. In this case, the inlet end 420 of the guide panel 400 may communicate with the inlet hole 340 of the partition wall 300.

[0088] In other words, the guide panel 400 can be positioned from the first protruding panel 100 toward the second protruding panel 200 while connected to the partition wall 300. Therefore, the guide panel 400 can protrude from the partition wall 300 and guide the gas flowing in the first protruding panel 100 into the second protruding panel 200.

[0089] The interior of the first protruding panel 100, the inlet hole 340 of the partition wall 300, and the guide panel 400 can form a path for gas to flow into the second protruding panel 200. The guide panel 400 can allow the final flow of gas introduced into the second protruding panel 200 through the inlet hole 340 of the partition wall 300.

[0090] In other words, the partition wall 300 and the guide panel 400 can delay the flow of gas from the first protruding panel 100 toward the second protruding panel 200 through the inlet portion 220 of the second protruding panel 200, so that the second protruding panel 200 expands immediately. Since the partition wall 300 and the guide panel 400 guide the second protruding panel 200 to expand later than the first protruding panel 100, it can prevent the second protruding panel 200 from fully expanding before the first protruding panel 100 has fully expanded.

[0091] In other words, in this disclosure, because the second protruding panel 200 expands after the first protruding panel 100 has fully expanded through the partition wall 300 and the guide panel 400, the first protruding panel 100 and the second protruding panel 200 can reach the body parts of the passenger seated in the event of a collision. Therefore, in the event of a collision, additional injuries due to delayed airbag deployment can be prevented.

[0092] Although not shown in the accompanying drawings, the number of guide panels 400 can be configured to correspond to the number of inlet holes 340 formed in the main body portion 320 of the partition wall 300. That is, when multiple inlet holes 340 are formed in the partition wall 300, multiple guide panels 400 can be connected to the partition wall 300, such that each of the multiple guide panels 400 is connected to a corresponding one of the inlet holes 340.

[0093] refer to Figure 11When a tilting collision occurs and the passenger's head contacts the second protruding panel 200, the guide panel 400 can bend. Therefore, it prevents a large amount of gas contained in the second protruding panel 200 from rapidly flowing towards the first protruding panel 100. Thus, by preventing a rapid decrease in the amount of expansion of the second protruding panel 200, a rapid decrease in the supporting force of the second protruding panel 200 is prevented. Therefore, it prevents additional head injuries to the passenger due to the rapid decrease in the expansion of the second protruding panel 200.

[0094] According to one embodiment of this disclosure, a partition wall provided in the unfolded portion can prevent a rapid decrease in the amount of gas flowing from the second protruding panel to the first protruding panel. Therefore, in the event of a tilting collision and the passenger's head contacting the second protruding panel, a rapid decrease in the expansion amount of the second protruding panel is prevented, thereby preventing a rapid decrease in the supporting force of the second protruding panel.

[0095] Another example of a partition wall will be described below.

[0096] Figure 12 This is a view showing another example of a partition wall, and Figure 13 It is shown that it is located in the first protruding panel Figure 12 A cross-sectional view of the partition wall. Figure 14 This is a view showing the partition wall configured as a curve. Figure 15 It shows the formation of the entrance. Figure 12 A cross-sectional view of the partition wall and the second protruding panel.

[0097] Reference Figures 12 to 15 The partition wall 300 can be disposed in the unfolded portion. The partition wall 300 can cover the entrance portion 220 of the second protruding panel 200. The partition wall 300 may include a main body portion 320, a recess portion 340, and a connecting portion 360.

[0098] The main body 320 may form the exterior of the partition wall 300. The main body 320 may support the connecting portion 360. The main body 320 may be provided at the inlet portion 220 formed in the second protruding panel 200. Therefore, the main body 320 may cover a portion of the inlet portion 220 of the second protruding panel 200 to prevent gas flowing in the first protruding panel 100 from being introduced into the second protruding panel 200.

[0099] The recess 340 may be provided at each corner of the main body portion 320. More specifically, the recess 340 may be a portion recessed into the corner of the main body portion 320. Since the recess 340 is provided at each corner of the main body portion 320, a plurality of recesses 340 may be formed.

[0100] The connecting portion 360 may be disposed between the recesses 340 and connected to the boundary between the first protruding panel 100 and the second protruding panel 200. The connecting portion 360 may include a first connecting portion 362 and a second connecting portion 364.

[0101] Each of the first connecting portion 362 and the second connecting portion 364 may have a shape that protrudes from the main body portion 320. More specifically, the first connecting portion 362 may include a 1-1 connecting portion 362a and a 1-2 connecting portion 362b protruding from two sides of the main body portion 320, and the second connecting portion 364 may include a 2-1 connecting portion 364a and a 2-2 connecting portion 364b protruding from the main body portion 320 and configured to intersect with the first connecting portion 362.

[0102] When the recess 340 is formed in the main body portion 320, the connecting portion 360 may have a shape that protrudes from the main body portion 320. However, the connecting portion 360 is not limited to this. The recess 340 is disposed between the first connecting portion 362 and the second connecting portion 364 of the connecting portion 360, and the recess 340 may be formed such that the first connecting portion 362 and the second connecting portion 364 protrude from the main body portion 320. Therefore, the size or shape of the recess 340 can be changed without limitation depending on the size or shape of the connecting portion 360. In addition, the size or shape of the connecting portion 360 can be changed depending on the size or shape of the recess 340.

[0103] Using the main body 320, the connecting portion 360 can be provided at a part of the inlet portion 220 formed in the second protruding panel 200. Therefore, using the main body 320, the connecting portion 360 can cover a part of the inlet portion 220 of the second protruding panel 200 to prevent gas flowing in the first protruding panel 100 from being introduced into the second protruding panel 200.

[0104] As described above, with the partition wall 300 disposed in the unfolded portion (more specifically, covering the entrance portion 220 of the second protruding panel 200), the partition wall 300 may form at least two or more entrances I with the inner surface of the second protruding panel 200.

[0105] Further reference Figure 15 The recess 340 of the partition wall 300 can form an entrance I with the second protruding panel 200. More specifically, the first connecting portion 362 of the partition wall 300, including a 1-1 connecting portion 362a and a 1-2 connecting portion 362b, and the second connecting portion 364, including a 2-1 connecting portion 364a and a 2-2 connecting portion 364b, can be connected to the boundary between the first protruding panel 100 and the second protruding panel 200.

[0106] Therefore, inlet I can be formed between the edge region of the partition wall 300 and the inner surface of the second protruding panel 200. Inlet I can connect the interior of the first protruding panel 100 and the interior of the second protruding panel 200. That is, inlet I can serve as a channel through which gas is introduced from the first protruding panel 100 toward the second protruding panel 200.

[0107] As described above, compared to the absence of the partition wall 300, the passenger airbag 1 according to one embodiment of the present disclosure can delay the time it takes for gas to be introduced into the second protruding panel 200 through the partition wall 300 disposed at the boundary between the first protruding panel 100 and the second protruding panel 200. This is to prevent the second protruding panel 200 from deploying earlier than the first protruding panel 100.

[0108] More specifically, when gas is generated from the inflator, the gas flows from the first protruding panel 100 to the second protruding panel 200 in the direction of gas supply. In this case, when the partition wall 300 is not present, it is possible that only the second protruding panel 200 is fully inflated due to the flow of gas toward the second protruding panel 200, even when the first protruding panel 100 is not fully inflated.

[0109] This could lead to a problem where the passenger airbag 1 cannot reach the passenger's body parts in the event of a collision. Therefore, a partition wall 300 can be provided in the deployed portion to prevent this problem. That is, since the area of ​​the inlet portion 220 of the second protruding panel 200 is reduced due to the partition wall 300, the amount of gas flowing from the first protruding panel 100 to the second protruding panel 200 is reduced. Therefore, the second protruding panel 200 can be deployed after the first protruding panel 100 has fully deployed.

[0110] As described above, since a structure is provided in which the second protruding panel 200 expands after the first protruding panel 100 has fully expanded through the partition wall 300, the deployed portion can reach the body part of the passenger seat within the time range calculated during the manufacturing process in the event of a collision. Therefore, in the event of a collision, additional injuries due to delayed airbag deployment can be prevented.

[0111] Furthermore, since the partition wall 300 is located at the boundary between the first protruding panel 100 and the second protruding panel 200, the area of ​​the inlet portion 220 formed in the second protruding panel 200 can be reduced. This means that when gas is introduced into the second protruding panel 200, the amount of gas flowing from the second protruding panel 200 to the first protruding panel 100 is less than the amount of gas in the conventional case without the partition wall 300. Therefore, when the passenger airbag 1 deploys, the tension of the second protruding panel 200 can be maintained. Therefore, when the second protruding panel 200 contacts the passenger's head, the phenomenon of the second protruding panel 200 being pushed by the force of the passenger's head contacting the second protruding panel 200 can be prevented.

[0112] Reference Figure 12 and Figure 13 The first distance D1 from the end of the 1-1 connecting portion 362a of the partition wall 300 to the end of the 1-2 connecting portion 362b can be greater than the first width W1 of the second protruding panel 200. Additionally, referring to... Figure 12 and Figure 14 The second distance D2 from the end of the 2-1 connecting portion 364a of the partition wall 300 to the end of the 2-2 connecting portion 364b can be greater than the second width W2 of the entrance portion 220 of the second protruding panel 200.

[0113] Therefore, as Figure 12 and Figure 14 As shown, with the partition wall 300 located at the boundary between the first protruding panel 100 and the second protruding panel 200 covering the inlet portion 220 of the second protruding panel 200, the partition wall 300 can be configured to bend towards the first protruding panel 100. This is to prevent the amount of gas contained in the second protruding panel 200 from decreasing rapidly, and to maintain the inflation state of the second protruding panel 200 by reducing the amount of gas returning from the second protruding panel 200 to the first protruding panel 100.

[0114] In this embodiment, such as Figure 12 and Figure 15 As shown, although recesses 340 of the partition wall 300 are provided at each corner of the main body portion 320, this disclosure is not limited thereto. Recesses 340 of the partition wall 300 can be formed not only at each corner of the main body portion 320, but also in the area where the connecting portion 360 is provided. Therefore, the entrance I formed using the partition wall 300 and the unfolded portion can also be formed in areas other than the corner areas of the second protruding panel 200.
