Description

Side airbags, seat systems and vehicles

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on December 29, 2023, with application number 202323658270.5 and application name “Side Airbag, Seat System and Vehicle,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the technical field of side airbags, and in particular to a side airbag, a seat system, and a vehicle. Background Art

[0003] With the continuous development of automobiles and other vehicles, users have increasingly higher demands for vehicle safety. Therefore, automobiles and other vehicles are equipped with side airbags that can be stored in a folded state. When a side collision occurs, the side airbags rapidly inflate from the folded state to the expanded state. During this process, the side airbags deploy and inflate between the seated occupants and the side of the vehicle, from the rear to the front. Thus, the deployed and inflated side airbags reduce injuries to the occupants in a side collision. However, existing side airbags do not effectively lift the arms, thus failing to provide adequate protection for the occupants. Summary of the Invention

[0049] With the development of the automotive industry and consumer demand, drivers and passengers are increasingly demanding higher levels of vehicle safety. Therefore, vehicles are equipped with side airbags that are stored in a folded state. In the event of a side collision, the side airbags rapidly inflate from the folded state to the expanded state. During this process, the side airbags deploy and inflate between the seated occupant and the side of the vehicle, from the rear to the front. This deploying and inflating side airbags thus reduces injuries to occupants in a side collision.

[0050] However, since the arms of drivers and passengers are often in a drooping position when riding in a vehicle, in related technologies, when a vehicle is involved in a side collision, the side airbags cannot effectively penetrate under the arms of the drivers and passengers, and thus cannot effectively lift the arms of the drivers and passengers, which inevitably causes a large impact force on the arms of the drivers and passengers. In severe cases, the arms of the drivers and passengers may be squeezed and damaged in the chest and other parts of the body, and the drivers and passengers cannot be effectively protected.

[0051] Please refer to Figures 1 and 2. Figure 1 is a partial structural diagram 1 of a vehicle provided in one embodiment of the present disclosure, and Figure 2 is a partial structural diagram 2 of a vehicle provided in one embodiment of the present disclosure.

[0052] Based on this, the present disclosure provides a vehicle 1000, which includes a seat system 100 and a vehicle body 200. The seat system 100 is installed on the vehicle body 200 and is used for seating passengers.

[0053] Please refer to Figures 1 to 4. Figure 3 is a structural diagram 1 of a seat system provided in an embodiment of the present disclosure. Figure 4 is a structural diagram 2 of a seat system provided in an embodiment of the present disclosure.

[0054] The present disclosure also provides a seat system 100, comprising a seat 10 and a side airbag 30. The seat 10 is mounted on a vehicle body 200 and is used to seat a passenger. The side airbag 30 is mounted on the backrest of the seat 10, near a door of the vehicle body 200. When the vehicle 1000 is involved in a side collision, the side airbag 30 rapidly inflates from a folded state to an expanded state. During this process, the side airbag 30 deploys and inflates between the passenger seated in the seat 10 and the door of the vehicle body 200, from the side and rear of the seat system 100 toward the front of the seat system 100. Portions of the side airbag 30 can penetrate under the passenger's arms and lift them. When fully inflated, the side airbag 30 is partially located in the space between the passenger's arms and the chest and abdomen. Thus, the deployed and inflated side airbag 30 reduces the damage to the occupants during a side collision of the vehicle 1000 .

[0055] Please refer to Figures 5 and 6. Figure 5 is an assembly diagram of a side airbag provided in accordance with an embodiment of the present disclosure. Figure 6 is a structural diagram of an airbag provided in accordance with an embodiment of the present disclosure.

[0056] The present disclosure provides a side airbag 30 that is designed to be installed, after folding, on the side of a seat 10 of a vehicle 1000 near a door of the vehicle 1000. When a side collision occurs on the vehicle 1000, the side airbag 30 rapidly inflates from its folded state to its expanded state. During this process, the side airbag 30 deploys and inflates between the occupant seated on the seat 1000 and the door of the vehicle body 200, from the rear toward the front of the vehicle 1000. This deployed and inflated side airbag thus reduces injuries to the occupants of the vehicle 1000 in a side collision.

[0057] In this embodiment, the side airbag 30 includes an airbag 31 and a gas generator 33. The airbag 31 is designed to expand after inflation, providing a cushioning protection between the driver and the door of the vehicle 1000. The gas generator 33 is mounted on the airbag 31 and communicates with the airbag 31 to inflate the airbag 31. The airbag 31 includes a first bag surface 31a and a second bag surface 31b. The periphery of the first bag surface 31a and the periphery of the second bag surface 31b are sealed together to form the airbag 31. The gas generator 33 is mounted on the first bag surface 31a. The gas generator 33 communicates with the airbag 31 and is used to inflate the airbag 31. The gas generator 33 is mounted on the airbag 31 and is positioned on the first bag surface 31a, i.e., the gas generator 33 is spaced apart from the junction of the first bag surface 31a and the second bag surface 31b, so that the gas generator 33 is mounted off-center on the airbag 31. During the inflation and expansion process of the airbag 31, the eccentric mounting of the gas generator 33 allows the airbag 31 to penetrate under the occupant's arm and quickly lift the occupant's arm. This helps prevent the occupant's arm from squeezing the chest or ribs, thereby minimizing damage to the chest or ribs caused by a short reaction time and delayed arm lift. Furthermore, since the fully deployed and inflated airbag covers the occupant's chest, abdomen, and shoulder areas, it reduces damage to the occupant caused by surrounding components.

[0058] It should be understood that the gas generator 33 in this embodiment generates a large amount of gas through a chemical reaction between the chemical substances within the gas generator 33, thereby deploying and inflating the airbag 31 of the side airbag 30. In other embodiments, the gas generator 33 may also be another device capable of generating gas, and this disclosure is not limited thereto.

[0059] In this embodiment, the airbag 31 of the side airbag 30 lifts the occupant's arm during inflation, removing it before the force acting on the occupant's chest reaches a dangerous level. For example, a side collision occurs at 0ms. The inflator 33 of the side airbag 30 ignites after 10ms, generating a large amount of gas and inflating the airbag 31. The occupant's arm is fully lifted around 25ms, and the occupant's chest is compressed to its maximum extent by the airbag 31 between 30 and 40ms.

[0060] Referring to Figures 5 and 6, in one embodiment, the first bag surface 31a and the second bag surface 31b are symmetrically arranged. That is, when the first bag surface 31a and the second bag surface 31b do not form the air bag 31, the first bag surface 31a and the second bag surface 31b are symmetrical about a symmetry line L. Because the first bag surface 31a and the second bag surface 31b are symmetrically arranged, and the gas generator 33 is disposed on the first bag surface 31a, that is, the gas generator 33 is spaced apart from the symmetry line L between the first bag surface 31a and the second bag surface 31b, the gas generator 33 is mounted eccentrically on the air bag 31. During the inflation and expansion process of the air bag 31, the eccentric mounting of the gas generator 33 on the air bag 31 allows the inflated air bag 31 to more effectively penetrate under the driver's arm and lift the driver's arm.

[0061] It is understandable that in some other embodiments, in order to produce a specific lateral expansion effect after the air bag 31 is unfolded and inflated, the first bag surface 31a and the second bag surface 31b can be an asymmetric structure, and the present disclosure does not limit this.

[0062] Please refer to Figures 5 and 6. In one embodiment, the first bag surface 31a and the second bag surface 31b are integrally formed, and the second bag surface 31b is folded in half relative to the first bag surface 31a along the symmetry line L. The gas generator 33 is spaced apart from the symmetry line L so that the position at which the gas generator 33 inflates the airbag 31 is eccentrically arranged, thereby causing the airbag 31 to expand laterally after being unfolded and inflated. The gas in the airbag 31 is quickly squeezed and can overlap with the driver's arm, so that the airbag 31 drills under the driver's arm and quickly lifts the driver's arm, which is beneficial to prevent the driver's arm from squeezing the chest or ribs and other parts, thereby reducing the risk of damage to the chest or ribs and other parts caused by the driver's arm due to short reaction time and untimely arm lifting.

[0063] It should be understood that in some other embodiments, the first bag surface 31a and the second bag surface 31b can be split structures. After the first bag surface 31a and the second bag surface 31b are overlapped, the periphery of the first bag surface 31a and the periphery of the second bag surface 31b are sealed and connected to form the air bag 31. It is only necessary to ensure that the gas generator 33 and the sealed connection between the first bag surface 31a and the second bag surface 31b are spaced apart. The present disclosure does not impose any restrictions on this.

[0064] It can be understood that the gas generator 33 of the side airbag 30 is installed on the seat back. When the side airbag 30 is in an inflated state, the connecting line between the first bag surface 31a and the second bag surface 31b is located in the space under the arms and surrounded by the chest and abdomen of the driver and passenger.

[0065] Referring to Figures 1 to 4, 5, and 6, in one embodiment, a mounting hole 311 is provided on the first bag surface 31a. The gas generator 33 passes through the mounting hole 311, so that at least a portion of the gas generator 33 is located within the air bag 31. The gas generator 33 generates gas within the air bag 31 to inflate the air bag 31. Specifically, in this embodiment, the mounting hole 311 is a circular hole. It is understood that in other embodiments, the mounting hole 311 can also have a shape similar to that of the gas generator 33, such as a polygonal hole, an elliptical hole, etc., and this disclosure is not limited thereto.

[0066] In some embodiments, a fixing hole 312 is further provided on the first bag surface 31a, and the fixing hole 312 is used for passing the fixing screw of the gas generator 33 to fix the gas generator 33 to the seat 10 of the vehicle 1000. Specifically, in this embodiment, the number of the fixing holes 312 is two. It is understandable that in other embodiments, the number of the fixing holes 312 includes but is not limited to 1, 2, 3, etc., and the present disclosure does not impose any limitation on this. Specifically, in this embodiment, the fixing hole 312 is a circular hole. It is understandable that in other embodiments, the fixing hole 312 can also be a shape similar to the shape of the screw of the gas generator 33, such as a polygonal hole, an elliptical hole, etc., and the present disclosure does not impose any limitation on this.

[0067] In some embodiments, the first bag surface 31a is further provided with an anti-fool hole 313, which is a special-shaped hole. The anti-fool hole 313 is used by assembly workers to better identify the side airbags installed on the driver's seat and the passenger seat to prevent incorrect installation that may result in ineffective protection of the driver and passengers. Specifically, in this embodiment, for example, the anti-fool hole 313 of the side airbag installed on the driver's seat is a quadrilateral hole, while the anti-fool hole 313 of the side airbag installed on the passenger seat may be a triangle. It is understood that in other embodiments, the anti-fool hole 313 may also be a special-shaped hole such as a pentagonal hole or an elliptical hole, and this disclosure does not limit this.

[0068] It should be understood that, in this embodiment, the assembly hole 311, the fixing hole 312 and the fool-proof hole 313 can be arranged in a straight line, that is, the center of the assembly hole 311, the center of the fixing hole 312 and the center of the fool-proof hole 313 are located on the same straight line, and the straight line formed by the center of the assembly hole 311, the center of the fixing hole 312 and the center of the fool-proof hole 313 is arranged parallel to the axis M of the gas generator 33, so as to facilitate the installation of the gas generator 33 on the first bag surface 31a.

[0069] In some embodiments, the second bag surface 31 b has an air vent 314 . After the air bag 31 is inflated and the impact caused by the side collision of the vehicle 1000 is resolved, the air vent 314 is used to release the gas in the air bag 31 so that the driver and passenger can get out of the seat 10 .

[0070] In some embodiments, the airbag 31 further includes a suture 315, which seals the perimeter of the first bag surface 31a and the perimeter of the second bag surface 31b. The suture 315 sews and seals the perimeters of the first bag surface 31a and the second bag surface 31b together, ensuring a sealed connection between the perimeters of the first bag surface 31a and the perimeter of the second bag surface 31b, thereby enhancing the stability of the airbag 31. When the side airbag 30 is inflated, the suture 315 between the first bag surface 31a and the second bag surface 31b is located within the space between the occupant's arms and the chest and abdomen.

[0071] It should be understood that in some other embodiments, the periphery of the first bag surface 31a and the periphery of the second bag surface 31b can be bonded together to form a seal by glue or other adhesives, and the present disclosure does not limit this.

[0072] Please refer to FIG. 7 , which is an assembly diagram of an air bag and a gas generator provided in one embodiment of the present disclosure.

[0073] In one embodiment, the gas generator 33 has an axis M, which is parallel to the symmetry line L between the first bag surface 31a and the second bag surface 31b. The axis M of the gas generator 33 is parallel to the symmetry line L between the first bag surface 31a and the second bag surface 31b, so that the gas generator 33 is parallel to the symmetry line L relative to the first bag surface 31a and the second bag surface 31b, facilitating the overall folding and installation of the side airbag 30.

[0074] Furthermore, the distance between the axis M of the gas generator 33 and the symmetry line L between the first bag surface 31a and the second bag surface 31b is in the range of [50, 120] mm. For example, the distance between the axis M of the gas generator 33 and the symmetry line L between the first bag surface 31a and the second bag surface 31b is 100 mm. By limiting the distance between the axis M of the gas generator 33 and the symmetry line L between the first bag surface 31a and the second bag surface 31b to [50, 120] mm, the side airbag 30 can be prevented from striking the right abdomen of the occupant due to an excessively small distance between the gas generator 33 and the symmetry line L between the first bag surface 31a and the second bag surface 31b. It can also be prevented from causing the side airbag 30 to only lift the occupant's forearm and fail to lift the entire arm due to an excessively large distance between the gas generator 33 and the symmetry line L between the first bag surface 31a and the second bag surface 31b.

[0075] It can be understood that according to the structure and size design of the vehicle 1000 and the seat system 100, the distance between the axis M of the gas generator 33 and the symmetry line L of the first bag surface 31a and the second bag surface 31b can also be 50mm, 80mm, 110mm, etc. The designer can design the distance between the axis M of the gas generator 33 and the symmetry line L of the first bag surface 31a and the second bag surface 31b according to specific needs, and the present disclosure does not limit this.

[0076] Please refer to FIG8 , which is an assembly diagram of an air bag and a gas generator provided in another embodiment of the present disclosure.

[0077] In another embodiment, the axis M of the gas generator 33 is inclined relative to the symmetry line L between the first bag surface 31a and the second bag surface 31b. Specifically, the gas generator 33 is tilted relative to the symmetry line L between the first bag surface 31a and the second bag surface 31b. With the axis M of the gas generator 33 tilted relative to the symmetry line L between the first bag surface 31a and the second bag surface 31b, the gas generator 33 inflates the airbag 31, causing the airbag 31 to expand laterally. This inflates the airbag 31 under the occupant's arm and lifts the occupant's arm, further enhancing the lifting effect of the side airbag 30 on the occupant's arm.

[0078] Furthermore, the inclination angle between the axis M of the gas generator 33 and the symmetry line L between the first and second bag surfaces 31a, 31b is in the range of [10, 30]°. For example, the inclination angle between the axis M of the gas generator 33 and the symmetry line L between the first and second bag surfaces 31a, 31b is 20°. By limiting the inclination angle between the axis M of the gas generator 33 and the symmetry line L between the first and second bag surfaces 31a, 31b to the range of [10, 30]°, it is possible to avoid situations where the inclination angle between the gas generator 33 and the symmetry line L between the first and second bag surfaces 31a, 31b is too small or too large, resulting in a poor arm-lifting effect for the driver and passenger.

[0079] Furthermore, the spacing range between one end of the gas generator 33 close to the symmetry line L of the first bag surface 31a and the second bag surface 31b and the symmetry line L is [0, 130] mm, and the spacing range between one end of the gas generator 33 away from the symmetry line L of the first bag surface 31a and the second bag surface 31b and the symmetry line L is [60, 190] mm.

[0080] It can be understood that, according to the structure and size design of the vehicle 1000 and the seat system 100, the inclination angle between the axis M of the gas generator 33 and the symmetry line L of the first bag surface 31a and the second bag surface 31b can also be 15°, 22°, 25°, etc. The designer can design the inclination angle between the axis M of the gas generator 33 and the symmetry line L of the first bag surface 31a and the second bag surface 31b according to specific needs, and the present disclosure does not limit this.

[0081] Please refer to Figures 4, 5, 9 and 10. Figure 9 is a diagram 1 of the folding process of a side airbag provided in an embodiment of the present disclosure. Figure 10 is a diagram 2 of the folding process of a side airbag provided in an embodiment of the present disclosure.

[0082] The side airbag 30 includes a deployed state, a folded state, and an inflated state. In the deployed state, the first bag surface 31a and the second bag surface 31b are in contact with each other, and there is no gas in the airbag 31. The deployed side airbag 30 is folded using the folding method shown in Figures 9 and 10 to form a folded state. In the folded state, the gas generator 33 is exposed from the side airbag 30. The folded side airbag 30 is smaller in size, making it easier to install the side airbag 30 on the seat 10. The airbag 31 of the folded side airbag 30 is inflated to form an inflated state. In the inflated state, at least a portion of the first bag surface 31a and at least a portion of the second bag surface 31b are spaced apart. The side airbag 30 switches from the deployed state to the folded state by folding. When the gas generator 33 inflates the airbag 31, the side airbag 30 switches from a folded state to an expanded state. Since the side airbag 30 expands laterally after being deployed and inflated, the gas in the airbag 31 is quickly squeezed and can overlap with the driver's arm, so that the airbag 31 drills under the driver's arm and quickly lifts the driver's arm, which helps prevent the driver's arm from squeezing the chest or ribs and other parts, thereby protecting the driver.

[0083] The above are some implementation methods of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present disclosure. These improvements and modifications are also considered to be within the scope of protection of the present disclosure.
