Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle seat and a vehicle. Background Technology

[0002] Some vehicle seats offer a wide range of angle adjustments between the backrest and seat cushion, better meeting users' comfort needs. For example, zero-gravity seats, through the coordinated adjustment of the backrest and seat cushion, can more precisely match the body's curves and optimize body pressure distribution, thus better meeting users' comfort requirements.

[0003] However, vehicle seats with a wide range of angle adjustment between the backrest and seat cushion face the following technical problems: When the angle between the backrest and the seat cushion is large, the occupants cannot be properly restrained in the event of a collision, which can easily lead to injury. In particular, when a zero-gravity seat is in a zero-gravity position, the seat belt restraint system may not be able to provide the necessary restraint, exposing the occupants to safety risks.

[0004] To reduce occupant safety risks, some technologies use software logic to restrict the posture of vehicle seats while the vehicle is in motion. For example, the zero-gravity function may be disabled while the vehicle is in motion, and the seat may automatically adjust back to its designed position after the vehicle starts. Restricting the posture of vehicle seats while in motion via software logic is easy to implement and inexpensive, but it negatively impacts the user experience.

[0005] Some technologies incorporate a rapid return mechanism within the seat frame. This mechanism allows the vehicle seat to quickly return to its designed position after a collision, reducing occupant safety risks. Rapid return mechanisms are typically motor-driven. Their complex structure and high precision requirements result in high costs and quality risks.

[0006] Some technologies enhance seatbelt restraint by adding a lumbar retractor, thereby reducing occupant safety risks. However, adding a lumbar retractor significantly impacts the vehicle's seating arrangement space and affects the appearance of the vehicle seats and surrounding components. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] like Figure 1 and Figure 2 The vehicle seat shown includes a seat cushion, a seat back, a seat cushion air bag 3, a backrest air bag 4, and an inflation assembly. The seat cushion air bag 3 is installed in the seat cushion, and the backrest air bag 4 is installed in the seat back. The inflation assembly is connected to the seat cushion air bag 3 and the backrest air bag 4, and the inflation assembly can inflate the seat cushion air bag 3 and the backrest air bag 4. When inflated, the seat cushion air bag 3 can lift the supporting surface of the seat cushion; when inflated, the backrest air bag 4 can lift the supporting surface of the seat back.

[0024] Using the above technical solution, when the angle between the backrest and the seat cushion is large, in the event of a collision, the inflation component inflates the seat cushion airbag 3 and the backrest airbag 4, thereby lifting the bearing surfaces of the seat cushion and the backrest. The inflated seat cushion airbag 3 and backrest airbag 4 provide an upward-sloping cushioning force to the shoulders and legs of the occupant 8, preventing the occupant 8 from sliding out of the vehicle seat due to the impact force and sustaining injury. Furthermore, the lifted bearing surfaces of the seat cushion and backrest alter the occupant 8's posture, enhancing the restraint effect of the seatbelt restraint system. Including airbags in the seat cushion and backrest further improves the restraint effect of the seatbelt restraint system.

[0025] The aforementioned vehicle seats ensure the safety of occupants 8 during vehicle operation, allowing for significant seat adjustments. For example, the zero-gravity function reduces limitations on seat application, contributing to a better user experience.

[0026] Using the aforementioned vehicle seats does not require altering the existing seat frame, resulting in lower costs. Furthermore, it allows for the installation of seat cushion air bags 3, backrest air bags 4, and inflation components on different frame platforms, offering greater compatibility and economy.

[0027] The vehicle seats described above can be arranged in a concealed manner, with the seat cushion air bag 3, backrest air bag 4 and inflation components taking up less space and having less impact on the shape and appearance.

[0028] In some embodiments, such as Figure 2As shown, the seat cushion airbag 3 includes a first airbag portion 301 disposed at the front of the seat cushion, a second airbag portion 302 extending rearward from the left end of the first airbag portion 301, and a third airbag portion 303 extending rearward from the right end of the first airbag portion 301. The second airbag portion 302 and the third airbag portion 303 are spaced apart from each other. Using the above technical solution, firstly, the volume of the seat cushion airbag 3 can be reduced, thereby increasing the inflation speed of the seat cushion airbag 3; secondly, the second airbag portion 302 and the third airbag portion 303 can also restrain the left and right sides of the occupant 8, helping to improve the safety of the occupant 8; and thirdly, the installation and arrangement difficulty of the seat cushion airbag 3 can be reduced.

[0029] In some embodiments, such as Figure 2 As shown, the seat cushion airbag 3 is connected to the seat cushion frame 1 of the seat cushion. The first airbag part 301 is connected to the front frame 102 of the seat cushion frame 1, the second airbag part 302 is connected to the left frame 101 of the seat cushion frame 1, and the third airbag part 303 is connected to the right frame 103 of the seat cushion frame 1. Using the above technical solution, the frame of the seat cushion frame 1 provides support and mounting points for the seat cushion airbag 3, which is easy to install and has stable working performance.

[0030] In some embodiments, such as Figure 3 and Figure 4 As shown, after the seat cushion airbag 3 is inflated, the front end of the seat cushion airbag 3 is raised higher than the rear end. Using the above technical solution, after the seat cushion airbag 3 is inflated, the occupant's thighs are raised higher than their buttocks, thereby reducing the angle between the occupant's upper body and legs, and providing better restraint for the occupant's buttocks.

[0031] As a specific example, the seat cushion also includes seat cushion foam and a cover, the upper surface of which is the bearing surface of the seat cushion. The seat cushion foam and cover are mounted on the seat cushion frame 1, which provides a mounting position for the seat control module 7 and the seat cushion airbag.

[0032] In some embodiments, such as Figure 2 As shown, the backrest airbag 4 includes a fourth airbag portion 401 disposed at the top of the seat back, a fifth airbag portion 402 extending downward from the left end of the fourth airbag portion 401, and a sixth airbag portion 403 extending downward from the right end of the fourth airbag portion 401. The fifth airbag portion 402 and the sixth airbag portion 403 are spaced apart from each other. Using the above technical solution, firstly, the volume of the backrest airbag 4 can be reduced, thereby increasing the inflation speed of the backrest airbag 4; secondly, the fifth airbag portion 402 and the sixth airbag portion 403 can also restrain the left and right sides of the occupant 8, helping to improve the safety of the occupant 8; and thirdly, the installation and arrangement difficulty of the backrest airbag 4 can be reduced.

[0033] In some embodiments, such as Figure 2 As shown, the backrest airbag 4 is connected to the backrest frame 2 of the seat back. The fourth airbag part 401 is connected to the upper frame 202 of the backrest frame 2. The fifth airbag part 402 is connected to the left frame 201 of the backrest frame 2. The sixth airbag part 403 is connected to the right frame 203 of the backrest frame 2. This technical solution effectively utilizes the frame of the backrest frame 2 to provide support and mounting points for the backrest airbag 4, resulting in easy installation and stable performance.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, after the backrest airbag 4 is inflated, the upper part of the backrest airbag 4 is raised higher than the lower part of the backrest airbag 4. By adopting the above technical solution, after the seat cushion airbag 3 is inflated, the upper body of the occupant 8 is raised higher than the buttocks, thereby reducing the angle between the upper body and the legs of the occupant 8 and providing better restraint for the buttocks of the occupant 8.

[0035] In practical implementation, the seat back also includes backrest foam and a cover, with the front side of the cover serving as the load-bearing surface of the seat back. The backrest foam and cover are installed on the backrest frame 2, which provides mounting positions for the air pump 6, air tank 5, and backrest air bag 4.

[0036] In some embodiments, such as Figure 2 and Figure 5 As shown, the inflation assembly includes an air tank 5 and an air pump 6. The air tank 5 can controllably inflate the seat cushion air bag 3 and the backrest air bag 4, and the air pump 6 can controllably inflate the air tank 5. This technical solution allows the seat cushion air bag 3 and the backrest air bag 4 to be reused.

[0037] As a specific example, such as Figure 5 As shown, air pressure sensors are installed in the air tank 5, seat cushion air bag 3, and backrest air bag 4. The air tank 5 is a high-pressure air tank, which is normally filled with high-pressure air. The seat control module 7 is mounted on the vehicle seat and can transmit CAN signals with the vehicle ECU, controlling the opening and closing of the air pump 6 and the air tank 5.

[0038] As a preferred example, the vehicle seat is a zero-gravity seat.

[0039] like Figures 1 to 4 As shown, the working principle of the vehicle seat proposed in this application is illustrated using a zero-gravity seat as an example: When a collision occurs, the vehicle's ECU detects the collision and sends a signal to the seat control module 7. The seat control module 7 determines whether the occupant 8 is in a zero-gravity posture. If so, it controls the air tank 5 to open. After the air tank 5 opens, high-pressure gas quickly fills the seat cushion air bag 3 and the backrest air bag 4. The seat cushion air bag 3 and the backrest air bag 4 lift up the seat cushion foam and cover, as well as the backrest foam and cover. The air pressure sensors in the seat cushion air bag 3 and the backrest air bag 4 transmit air pressure information to the seat control module 7. When the seat control module 7 determines that the air bags are full, it sends a feedback signal to the vehicle's ECU, confirming that the zero-gravity seat occupant 8 cushioning mechanism has completed its response. The vehicle's display screen prompts the user to enter the zero-gravity seat occupant 8 protection state. At the same time, the seat control module 7 controls the cushioning air tank 5 to close and starts the cushioning air pump 6 to replenish the cushioning air tank 5.

[0040] The gas tank 5 stores high-pressure gas, which can quickly fill the seat cushion airbags 3 and backrest airbags 4 in the event of a collision. The filled seat cushion airbags 3 and backrest airbags 4 can lift up the seat cushion foam and cover, as well as the backrest foam and cover. When the occupant 8 is in a zero-gravity position, the lifted seat cushion foam and cover provide a cushioning force diagonally upward along the first arrow 9 for the occupant 8's legs, and the lifted backrest foam and cover provide a cushioning force diagonally upward along the second arrow 10 for the occupant 8's shoulders, preventing the occupant 8 from sliding out of the seat due to the impact force in a zero-gravity position and being injured. At the same time, the raised seat cushion airbags 3 and backrest airbags 4 will change the occupant 8's body posture, thereby improving the restraint effect of the seat belt restraint system.

[0041] This utility model also proposes a vehicle including the vehicle seat described in any of the above claims.

[0042] Vehicles can be, but are not limited to, pure electric vehicles (PEV / BEV), hybrid electric vehicles (HEV), range-extended electric vehicles (REEV), plug-in hybrid electric vehicles (PHEV), new energy vehicles, and gasoline vehicles.
