Abstract
Description
Technical Field
[0001] This application relates to the field of zero-gravity seat technology, and in particular to a zero-gravity seat protection device and protection method. Background Technology
[0002] Zero-gravity car seats are designed to minimize stress on occupants' muscles and bones through steep inclines (typically exceeding 120°) and raised leg rests, achieving extreme comfort. However, this unconventional seating posture also poses significant challenges to occupant safety during a collision. The injury patterns of occupants in zero-gravity seats differ significantly from those in traditional seating positions during a crash. Studies show that in a steeply reclined seating position, the risk of head, neck, and chest injuries is significantly increased, especially in the lumbar spine and pelvic region, where severe injuries are more likely due to the "sinking" phenomenon (occupants sliding down the seat during a collision). Summary of the Invention
[0003] This application aims to address at least one of the technical problems existing in the prior art. Therefore, one objective of this application is to provide a zero-gravity seat protection device and method, aiming to solve the problem of insufficient protection for occupants provided by zero-gravity seats.
[0004] In the first aspect, this application proposes a zero-gravity seat protection device, which includes a reset module, a seat belt module, and two airbag modules. The two airbag modules are respectively disposed on both sides of the seat, and each airbag module includes a side airbag and a seat cushion airbag. The two side airbags are adapted to form protection on both sides of the occupant, and the two seat cushion airbags are adapted to form protection under the occupant. The seat belt module includes a seat belt body and a retracting assembly. The retracting assembly is disposed in the backrest of the seat, and the fixing point of the seat belt body is disposed on the seat. The reset module is adapted to adjust the shape of the seat so that it resets from a zero-gravity posture to a standard posture.
[0005] According to some embodiments of this application, the side airbag includes a head protection unit and a torso protection unit, wherein the head protection unit is adapted to protect the occupant's head; and the torso protection unit is adapted to protect the occupant's torso.
[0006] According to some embodiments of this application, the front end of the seat cushion airbag and / or the end of the seat cushion airbag near the side of the seat has an upwardly protruding edge, which is suitable for restricting occupant displacement.
[0007] Secondly, this application proposes a zero-gravity seat protection method, employing the aforementioned zero-gravity seat protection device, characterized in that the zero-gravity seat protection method includes the following steps:
[0008] Real-time monitoring of vehicle driving status and environmental information to determine if there are potential collision risks; When a collision risk is determined, the potential collision direction is predicted; Based on the predicted impact direction, generate protection commands that match the impact direction; According to the protection command, the seat belt module, reset module and airbag module are controlled to perform protective actions before or during the impact.
[0009] According to some embodiments of this application, based on the predicted impact direction, a protective command matching the impact direction is generated, including: When a head-on collision is imminent, generate the first protection command; A second protective command is generated when a side collision is imminent.
[0010] According to some embodiments of this application, based on protective commands, the seatbelt module, reset module, and airbag module are controlled to perform protective actions before or during an impact, including: When a frontal collision is imminent, according to the first protection command, the control reset module resets the seat to the standard position, controls the seat belt module to tighten, and controls the deployment of the side seat cushion airbags. In the event of an impending side collision, the second protection command controls the tensioning of the seatbelt module and the deployment of the side airbags and seat cushion airbags on the same side as the impact direction.
[0011] According to some embodiments of this application, before real-time monitoring of vehicle driving status and environmental information to determine whether there is a potential collision risk, the method further includes: The system detects the occupant's position and the seat's posture. When the seat is in a zero-gravity position and the occupant is in place, the zero-gravity seat protection method is implemented.
[0012] Thirdly, this application proposes an electronic device, characterized in that it includes: a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the computer program to implement the above-mentioned zero-gravity seat protection method.
[0013] Fourthly, this application proposes a non-volatile computer-readable storage medium storing a computer program thereon, characterized in that the program is executed by a processor to implement the above-described zero-gravity seat protection method.
[0014] Fifthly, this application proposes a computer program product, including a computer program, characterized in that the computer program is executed to implement the above-described zero-gravity seat protection method.
[0015] This application, by incorporating a reset module, can quickly return the seat to its upright position in the event of a collision, avoiding injuries caused by zero-gravity posture. By installing a seatbelt module and mounting it on the seat, the seatbelt module moves synchronously with the backrest angle adjustment, ensuring a tight fit with the occupant when tensioned, preventing unadjustable gaps due to backrest angle adjustments. Side airbags provide protection for the occupant's head, neck, and chest, while seat cushion airbags provide protection from below, effectively limiting occupant movement and preventing collision injuries during impact. This application effectively protects occupants in the event of a collision, avoiding potential injuries from current restraint systems in large-angle collisions with zero-gravity seats; fills the gap in side protection for zero-gravity seats; avoids potential injuries from seat backrest reset during side impacts; enhances side protection; effectively prevents direct contact between occupants and vehicle interior materials; and ensures the seatbelt is unaffected by the seat back angle.
[0016] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation
[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0020] The zero-gravity seat protection device and protection method of this application are described below with reference to the accompanying drawings.
[0021] Zero-gravity car seats have two postures: zero-gravity and standard. The standard posture is the conventional posture of a car seat. In the zero-gravity posture, the large-angle tilt (usually the backrest tilt angle exceeds 120°) and raised leg rest minimize the stress on the occupant's muscles and bones, achieving a comfortable seating effect. It's important to note that the backrest tilt angle in the zero-gravity posture is not a fixed value but has a certain range of adjustment. In the event of a collision, the risk of head, neck, and chest injuries is significantly increased in a large-angle tilted seating position. Simultaneously, the occupant is prone to sliding relative to the seat, leading to serious injuries to the lumbar spine and pelvis. In zero-gravity seats, on the one hand, airbag protection is insufficient, failing to provide protection for critical areas; on the other hand, the seat belts use a conventional design, with the retractor assembly and some anchor points located on the vehicle frame structure. In the zero-gravity posture, the seat belts cannot fit snugly against the occupant's body, resulting in insufficient tension and very limited protective effect. It is difficult to restrain the occupant, making them prone to sliding and causing injury.
[0022] To address the aforementioned issues, this application proposes a zero-gravity seat protection device. By incorporating a reset module 40, the seat can be quickly reset to its upright position in the event of a collision, preventing injuries caused by the zero-gravity posture. By incorporating a seatbelt module 30 and mounting it on the seat 100, the seatbelt module 30 can move synchronously with the backrest angle adjustment, ensuring a tight fit with the occupant when tensioned, preventing gaps between the seatbelt module and the occupant due to backrest angle adjustments. Side airbags provide protection for the occupant's head, neck, and chest, while seat cushion airbags provide protection under the occupant. Combined with the seatbelt module, these elements effectively limit the occupant's movement during a collision, preventing displacement and impact injuries. The zero-gravity seat protection device of this application can provide effective protection for occupants, avoiding the injury that current restraint systems may cause to occupants in the event of a collision at a large angle in zero-gravity seats; it fills the gap in side protection of zero-gravity seats; it avoids the injury that may be caused to occupants when the seat back resets during a side collision; it enhances the side protection effect and effectively avoids direct contact between occupants and the vehicle interior; and the seat belt is not affected by the angle of the seat back.
[0023] like Figure 1 As shown, the zero-gravity seat protection device of this application includes two airbag modules, namely the first airbag module 10 and the second airbag module 20, which are installed on the seat 100.
[0024] The first airbag module 10 and the second airbag module 20 are respectively disposed on both sides of the seat 100, each including a side airbag and a seat cushion airbag; depending on the placement of the seat 100 inside the vehicle, one side of the seat 100 is closer to the vehicle frame (i.e., Figure 3 As shown on the right, the left side of seat 100), the other side is close to the adjacent seat (i.e. Figure 3 (As shown on the left, the right side of seat 100); for ease of description, the first airbag module 10 is located on the right side of seat 100, i.e., the adjacent seat side, and the second airbag module 20 is located on the left side of seat 100, i.e., the frame side.
[0025] The left / right side mentioned below refers to the left / right side of the vehicle (seat 100).
[0026] The first airbag module 10 includes a first side airbag 11, adapted to form protection on the side of the occupant.
[0027] Because seat 100 is close to another seat on its adjacent side, there is a possibility of collision between occupants causing injury; in order to improve the protective effect of the first side airbag 11, such as Figure 2 , 3As shown, the first side airbag 11 includes a head protection unit 111 and a torso protection unit 112. The head protection unit 111 protrudes beyond the torso protection unit 112 in the width direction of the seat 100. After deployment, the head protection unit 111 provides effective protection for the occupant's head and neck, preventing head-to-head contact between occupants. After deployment, the torso protection unit 112 provides effective protection for the occupant's torso, preventing impact between the occupant and other vehicle interior structures such as the dashboard. The first side airbag 11 can enclose the occupant's head and torso in the event of a side collision on the right side of the vehicle, preventing injury caused by collisions between occupants or between the occupant and the vehicle's interior structure.
[0028] Furthermore, in some embodiments, the head protection unit 111 and the torso protection unit 112 can be isolated from each other and deployed separately. Thus, when the first side airbag 11 is deployed due to a collision risk, even if one of the head protection unit 111 or the torso protection unit 112 malfunctions, the other can still deploy normally, providing basic protection and preventing the occupant from being in a state of zero or low protection on the side. In other embodiments, the head protection unit 111 and the torso protection unit 112 can be interconnected. This arrangement avoids protective gaps, allowing the shape of the first side airbag 11 to better conform to the occupant's side profile curve, improving the protective effect. Furthermore, it allows for rapid deployment of the first side airbag 11 in the event of a collision risk, simplifying the control logic, improving response speed, and quickly providing lateral protection for the occupant.
[0029] The first airbag module 10 also includes a first seat cushion airbag 12, adapted to form protection under the occupant on one side.
[0030] like Figure 5 , 6 As shown, the first seat cushion airbag 12 has an upwardly protruding first convex edge 121 at one end near the front side of the seat 100. The first convex edge 121 can provide certain restriction to the occupant when the occupant has a downward tendency, slow down or prevent the occupant from sliding down, thereby improving protection and reducing occupant injury.
[0031] Furthermore, the first seat cushion airbag 12 has an upwardly protruding second convex edge 122 at one end near the seat 100 adjacent to the seat. The second convex edge 122 can provide a certain lateral restraint to the occupant in the event of a side impact risk, reduce or prevent lateral displacement, thereby improving protection and reducing the risk of occupant injury.
[0032] Furthermore, the first seat cushion airbag 12 has a concave portion in the middle to adapt to the shape of the occupant's buttocks, improve the fit between the airbag and the occupant, and enhance the protective effect.
[0033] The second airbag module 20 includes a second side airbag 21, adapted to form protection on the side of the occupant.
[0034] like Figure 4 As shown, the second side airbag 21 is positioned at the corresponding location on the torso. After deployment, it provides effective protection for the occupant's torso, offering cushioning and isolation. In the event of a collision on the left side of the vehicle, the second side airbag 21 can isolate the occupant from the door, preventing hard contact between the occupant and the door trim panel, thereby reducing injury to the occupant.
[0035] The second airbag module 20 also includes a second seat cushion airbag 22, adapted to form protection under the occupant on the other side.
[0036] like Figure 5 , 6 As shown, the second seat cushion airbag 22 has an upwardly protruding third convex edge 221 at one end near the front side of the seat 100. The third convex edge 221 can provide certain restrictions on the occupant when the occupant has a downward tendency, slow down or prevent the occupant from sliding down, thereby improving protection and reducing occupant injury.
[0037] Furthermore, the second seat cushion airbag 22 has an upwardly protruding fourth convex edge 222 at one end near the frame side of the seat 100. The fourth convex edge 222 can provide a certain lateral restriction to the occupant in the event of a side collision risk, reduce or prevent lateral displacement, thereby improving protection and reducing the risk of occupant injury.
[0038] Furthermore, the second seat cushion airbag 22 has a concave portion in the middle to adapt to the shape of the occupant's buttocks, improving the fit between the airbag and the occupant and enhancing the protective effect.
[0039] Both the first airbag module 10 and the second airbag module 20 include side airbags and seat cushion airbags. The side airbags are suitable for forming protection on one side of the occupant, and the seat cushion airbags are suitable for forming protection under the occupant, thereby achieving an overall protective effect around the occupant.
[0040] like Figure 1 As shown, the zero-gravity seat protection of this application also includes a seat belt module 30 for securing the occupant's body and reducing the risk of collision.
[0041] like Figure 7 As shown, the seat belt module 30 is integrally mounted on the seat 100. The seat belt module 30 includes a seat belt body and a retractor assembly (not shown in the figures). The retractor assembly is disposed in the backrest of the seat 100, and the seat belt body is fixed to the seat 100 by multiple fixing points. Because the seat belt module 30 of this application is integrally connected to the seat 100, it moves with the tilt of the seat 100 backrest, providing effective tension and restraint for the occupant at any angle, thus providing effective protection.
[0042] like Figure 1As shown, the zero-gravity seat protection of this application also includes a reset module 40, which is used to adjust the shape of the seat 100 so that it resets from the zero-gravity posture to the standard posture.
[0043] The reset module 40 of this application can quickly and timely adjust the shape of the seat 100 to return it to the standard posture when there is a risk of collision. This can avoid the injury to the occupant caused by the zero-gravity posture when a collision occurs. Combined with the first airbag module 10, the second airbag module 20 and the seat belt module 30, it can provide effective protection for the occupant.
[0044] Furthermore, the zero-gravity seat protection device of this application also includes a collision detection module 50 and a control module 60. The collision detection module 50 is used to acquire vehicle driving data and external environment data, and to determine potential collision risks based on the vehicle driving data and external environment data. The control module 60 is used to control the operation of the first airbag module 10, the second airbag module 20, the seat belt module 30, and the reset module 40 when a potential collision risk exists. The control module 60 may be an ACU controller and is communicatively connected to the first airbag module 10, the second airbag module 20, the seat belt module 30, the reset module 40, and the collision detection module 50.
[0045] The zero-gravity seat protection device of this application, by setting a reset module 40, can quickly reset the seat 100 to its upright position when there is a risk of impact, avoiding the damage caused by the zero-gravity posture; by setting a seat belt module 30 and setting the seat belt module 30 on the seat 100, the seat belt module 30 can move synchronously with the backrest angle adjustment, and when tensioned, it fits tightly against the occupant, avoiding the creation of an unadjustable gap between the seat belt module and the occupant due to the backrest angle adjustment; by setting side airbags, it provides protection for the occupant's head, neck and chest; by setting seat cushion airbags, it provides protection under the occupant, and together with the seat belt module, it effectively limits the occupant's movement during the impact, avoiding collision damage caused by the occupant's displacement. The zero-gravity seat protection device of this application can provide effective protection for occupants, avoiding the injury that current restraint systems may cause to occupants in the event of a collision at a large angle in zero-gravity seats; it fills the gap in side protection of zero-gravity seats; it avoids the injury that may be caused to occupants when the seat back resets during a side collision; it enhances the side protection effect and effectively avoids direct contact between occupants and the vehicle interior; and the seat belt is not affected by the angle of the seat back.
[0046] Next, the zero-gravity seat protection method proposed in the embodiments of this application is described. The zero-gravity seat protection method of this application includes the following steps: S1. Real-time monitoring of vehicle driving status and environmental information to determine whether there is a potential collision risk; S2. When a collision risk is determined, predict the potential collision direction; S3. Based on the predicted impact direction, generate protection commands that match the impact direction; S4. According to the protection command, control the seat belt module 30, reset module 40 and airbag module to perform protective actions before or during the impact.
[0047] In step S1, the vehicle's driving status and environmental information are monitored in real time, acquiring vehicle driving data and environmental data. Vehicle driving data includes dynamic parameters such as vehicle speed, acceleration, and steering angle, as well as the posture of the zero-gravity seat, specifically the backrest tilt angle, and the occupant's position in the zero-gravity seat. Environmental data includes road signs, obstacle presence, distance to obstacles in front / to the side, relative speed, relative angle, road conditions, and weather conditions. Vehicle driving status and environmental information can be acquired in real time through various onboard sensors, millimeter-wave radar, etc., and some environmental data can also be obtained via network connection.
[0048] According to some embodiments of this application, before step S1, the method further includes: detecting the occupant's position and the posture of the seat 100; and executing a zero-gravity seat protection method when the seat 100 is in a zero-gravity posture and the occupant is in place. This embodiment can avoid energy waste and loss.
[0049] In step S2, based on the vehicle driving data and environmental data obtained in step S1, potential collision risks can be determined and potential collision directions can be predicted.
[0050] Step S3 specifically includes: S3.1 generates the first protection command when a frontal collision is imminent; S3.2 generates a second protection command when a side collision is imminent.
[0051] Correspondingly, step S4 specifically includes: When a frontal collision is about to occur, S4.1 controls the reset module 40 to reset the seat to the standard position according to the first protection command, controls the seat belt module 30 to tighten, and controls the deployment of the side seat cushion airbags. When a side collision is imminent, S4.2, according to the second protection command, controls the tension of the seat belt module 30 and controls the deployment of the side airbag and seat cushion airbag on the same side as the collision.
[0052] When a frontal collision is about to occur, the occupant tends to slide down. In step S4.1, based on the first protection command, the seat 100 is reset and the seat belt module 30 is tightened to effectively protect the occupant. At the same time, controlling the deployment of the first seat cushion airbag 12 and the second seat cushion airbag 22 can effectively limit the occupant's sliding movement, so that the occupant is buffered and protected during the reset of the seat 100, thereby improving the protection effect.
[0053] When a side impact is imminent, occupants tend to move relative to the vehicle body along the impact direction due to inertia. It should be noted that the impact direction described in this application refers to the direction in which the vehicle impacts the obstacle. For example, if the vehicle impacts the obstacle to the left, the impact occurs on the left side of the vehicle, and the occupants tend to move to the left. In step S4.2, based on the second protection command, the seatbelt module 30 is tightened to effectively protect the occupants. Simultaneously, the deployment of the side airbags and seat cushion airbags on the same side of the impact is controlled. The seat cushion airbags provide a certain degree of restraint, which can have a buffering effect. The side airbags protect the occupants from the same side of the impact, effectively preventing the occupants from colliding with the vehicle's internal structure.
[0054] It is important to note that side collisions include collisions to the left and right sides of the vehicle, i.e., collisions to the chassis and collisions to the adjacent seats. The degree of injury to occupants differs depending on the side of the collision. Therefore, step S3.2 specifically includes: S3.2.1 When a lateral collision is about to occur on the frame side, a third protection command is generated; S3.2.2 When a side collision with the adjacent seat is about to occur, a fourth protection command is generated.
[0055] Correspondingly, S4.2 specifically includes: S4.2.1 When a side collision is about to occur on the frame side, according to the third protection command, control the tension of the seat belt module 30, control the deployment of the side airbag and seat cushion airbag on the same side as the collision, and control the deployment of the side airbag on the opposite side of the collision. S4.2.2 In the event of an impending side collision to the adjacent seat side, the fourth protection command is used to control the tension of the seat belt module 30 and to control the deployment of the side airbag and seat cushion airbag on the same side as the collision.
[0056] In the event of an impending side-impact collision with the vehicle frame, in step S4.2.1, based on the third protection command, the seatbelt module 30 is tightened to effectively protect the occupants; the deployment of the first side airbag 11 and the first seat cushion airbag 12 on the same side of the collision is controlled, and the seat cushion airbag provides a certain limit to achieve a buffering effect. The side airbags protect the occupants from the same side of the collision, effectively preventing the occupants from colliding with interior structures such as the vehicle frame; at the same time, the deployment of the second side airbag 21 on the opposite side of the collision is controlled, effectively preventing the occupants in the seat 100 from colliding with structures such as the dashboard or other adjacent occupants, providing effective protection for the occupants on the non-impact side, and comprehensively improving the protection effect of this application.
[0057] In the event of an impending side impact to the adjacent seat, in step S4.2.2, based on the fourth protection command, the seat belt module 30 is tightened to effectively protect the occupant; the second side airbag 21 and the second seat cushion airbag 22 on the same side of the impact are controlled to deploy. The seat cushion airbag provides a certain limit to achieve a buffering effect, and the side airbags protect the occupant from the same side of the impact, which can effectively prevent the occupant from colliding with the vehicle interior structure or other occupants, thereby achieving an effective protection effect.
[0058] Furthermore, in some embodiments, step S2 further includes: When a collision risk is determined, the collision level is predicted based on the vehicle's driving status and environmental information.
[0059] Correspondingly, step S3 also includes: Based on the predicted impact direction and impact level, protective commands are generated that match the impact direction and impact level.
[0060] It should be noted that the impact level is classified according to the predicted severity of the impact, specifically into minor impact, moderate impact, severe impact, etc.
[0061] In the event of a minor or moderate impact, the first, third, or fourth protection command is generated based on the direction of the impact, and the seat belt module 30, reset module 40, and airbag module are controlled to perform protective actions before or during the impact.
[0062] In the event of a severe impact, a fifth protection command is generated. Based on this command, the seatbelt module 30 is tensioned, and the side airbags and seat cushion airbags of the first airbag module 10 and the second airbag module 20 are deployed simultaneously. This establishes effective protection on both sides of the occupant, preventing injuries from direct contact with the vehicle body, as well as injuries from the vehicle's interior structure, other occupants, and impact rebound, providing comprehensive and efficient protection for the occupant.
[0063] The following is a specific embodiment of this application, employing the aforementioned zero-gravity seat protection device. The zero-gravity seat protection device includes a first airbag module 10, a second airbag module 20, a seatbelt module 30, a reset module 40, a collision detection module 50, and a control module 60 (ACU controller). The zero-gravity seat protection method specifically includes: P1, the collision detection module 50 will determine whether the vehicle will collide based on the vehicle driving data. If it is determined that the vehicle will collide, it will immediately output the pre-collision information to the ACU controller. P2, the ACU controller analyzes the pre-collision information and seat posture information, identifies the collision direction, collision time, seat fore-and-aft position and backrest angle, and inputs the relevant information into the seat reset system (including reset module 40) and the restraint system (including seat belt module 30) and related components; if the collision direction is a frontal collision, proceed to steps P3-P5; if the collision direction is a side collision, proceed to steps P6-P8. P3, the seat reset module 40 recognizes the frontal collision signal, and the pyrotechnic generator ignites according to the pre-collision time, instantly resetting the seat back angle. Figure 8 As shown; P4, the first airbag module 10, the second airbag module 20 recognize the frontal collision signal, and the first seat cushion airbag 12 and the second seat cushion airbag 22 are ignited simultaneously; P5, the seat belt module 30 recognizes the frontal collision signal, completes ignition according to the ignition strategy, and completes occupant restraint; P6, Seat reset module 40 recognizes the side collision signal but does not react; P7, the first airbag module 10, and the second airbag module 20 identify the side collision signal and the direction of the vehicle collision. If the collision direction is to the left, the second seat cushion airbag 22 and the second side airbag 21 on the left and the first side airbag 11 on the right are ignited; if the collision direction is to the right, the first seat cushion airbag 12 and the first side airbag 11 on the right are ignited. S8, the seat belt module 30 recognizes the side collision signal, completes ignition according to the ignition strategy, and completes occupant restraint.
[0064] The zero-gravity seat protection method of this application can provide effective protection for occupants in the event of a collision risk, avoiding the injuries that current restraint systems may cause to occupants in collisions at large angles with zero-gravity seats; it fills the gap in side protection for zero-gravity seats; it avoids the injuries that may be caused to occupants when the seat back resets during a side collision; it enhances the side protection effect and effectively avoids direct contact between occupants and the vehicle interior; and the seat belts are not affected by the seat back angle. Moreover, this application can actively identify collision conditions and has a wide range of applications.
