Description

Technical Field

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

[0002] In related technologies, the development of zero-gravity seats focuses primarily on structural design, such as resilient seat cushions, special backrest structures, seat airbags, and three-stage pretensioning seat belts, to ensure ride comfort and a certain level of safety. However, protection measures for the occupant's lower limbs, especially the feet and legs, are relatively lacking. This design flaw means that in a collision, the occupant's lower limbs, lacking effective restraint, are prone to significant forward displacement. This can not only impact the front seats or frontal components but also easily trigger abdominal subduction, thereby weakening the protective effect of the seat belts and increasing the risk of severe abdominal injuries. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, one objective of this utility model is to provide a seat that can not only effectively reduce the displacement of the occupant in a collision, but also reduce the impact injury caused by inertia by slowing down the forward or lateral movement of the occupant's body, thereby significantly improving the protective effect of the entire occupant restraint system and providing more comprehensive and effective safety protection for the occupant.

[0005] Therefore, the second objective of this utility model is to provide a vehicle.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model discloses a seat, comprising: a seat body, the seat body including a seat cushion, a backrest and a leg rest, the backrest being connected to the rear end of the seat cushion and the leg rest being connected to the front end of the seat cushion; an airbag module, the airbag module being disposed on the leg rest, the airbag module being used to restrict the lower limb movement of an occupant on the seat body after deployment; and an airbag controller, the airbag controller being electrically connected to the airbag module, the airbag controller controlling the state of the airbag module based on a received vehicle status signal.

[0007] According to an embodiment of the present invention, an airbag module is provided on the footrest of the seat body. The airbag module is electrically connected to an airbag controller, enabling the airbag controller to control the state of the airbag module based on the vehicle status signal. When necessary, such as in the event of a vehicle collision, the airbag controller will control the airbag module to deploy rapidly to restrict the movement of the occupant's lower limbs on the seat body, providing solid support and effective restraint for the occupant's lower limbs. This not only effectively reduces the occupant's displacement during a collision, but also reduces the impact injury caused by inertia by slowing down the occupant's forward or lateral movement, thereby significantly improving the protective effect of the entire occupant restraint system and providing more comprehensive and effective safety protection for the occupant.

[0008] In addition, the seat according to the above embodiments of the present invention may also have the following additional technical features:

[0009] In some embodiments, the airbag module includes: an airbag housing disposed on the leg rest; an air bag and a gas generator disposed within the airbag housing; the air bag being connected to the gas generator; and the gas generator being electrically connected to the airbag controller; when the gas generator is activated, it inflates the air bag to deploy it and thereby restrict the occupant's lower limb movement.

[0010] In some embodiments, the air bag includes a plurality of air columns arranged in sequence, with an inflation hole provided between adjacent air columns.

[0011] In some embodiments, the plurality of air columns are folded into a fan shape; and / or the plurality of air columns extend in a left-right direction after unfolding.

[0012] In some embodiments, the air bag has flaps on both sides, and the flaps are connected to the leg rest.

[0013] In some embodiments, the bottom of the air bag is connected to the gas generator, and the top of the air bag is provided with at least one reinforcing member, which is connected to the leg support.

[0015] In some embodiments, the airbag box is mounted on the front end and / or the left and right sides of the leg rest; and / or the gas generator is configured as a pyrotechnic gas generator.

[0016] In some embodiments, the airbag controller is configured to control the airbag module to be in an active, usable state when it receives a signal indicating that the leg rest is in an open state and a signal indicating that the backrest angle has reached or exceeded a set angle; and to control the airbag module to deploy when it receives a signal indicating that the airbag is to be deployed and the airbag module is in an active state.

[0017] To achieve the above objectives, a second aspect of the present invention discloses a vehicle including a seat as described in the first aspect of the present invention.

[0018] According to an embodiment of this utility model, an airbag module is provided on the footrest of the seat body in the vehicle. The airbag module is electrically connected to the airbag controller, enabling the airbag controller to control the state of the airbag module based on the vehicle status signal after receiving the signal. When necessary, such as in the event of a collision, the airbag controller will control the airbag module to deploy rapidly to restrict the movement of the occupant's lower limbs on the seat body, providing solid support and effective restraint for the occupant's lower limbs. This not only effectively reduces the displacement of the occupant during a collision, but also reduces the impact injury caused by inertia by slowing down the forward or lateral movement of the occupant's body. This significantly improves the protective effect of the entire occupant restraint system, providing more comprehensive and effective safety protection for the occupant.

[0019] Additional aspects and advantages of this invention 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 the invention. Attached Figure Description

[0020] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0021] Figure 1 This is a structural schematic diagram of a seat according to an embodiment of the present invention;

[0022] Figure 2 This is a schematic diagram of the structure of an air bag and a bag sheet according to an embodiment of the present invention;

[0023] Figure 3 This is a structural block diagram of a vehicle according to an embodiment of the present invention. Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0025] In the field of zero-gravity seat occupant protection, existing regulations have clearly defined multiple injury indicators, covering critical body parts such as the head and neck, chest, thoracic / lumbar spine, abdomen, and lower limbs. To mitigate injuries to these areas, engineers have developed innovative solutions such as resilient seat frames and seat cushion airbags. These solutions have proven effective in reducing chest compression and lumbar spine stress in practical applications, thereby improving occupant safety to some extent.

[0026] However, there is currently no specific optimization solution for the increased foot acceleration, increased force on the lower leg, and higher injury index that may result from the foot impacting the front seat. This is because when an occupant in a zero-gravity seat leans forward due to inertia during a collision, their feet are likely to violently impact the front seat, leading to a sharp increase in foot acceleration, enormous impact force on the lower leg, and potentially a higher injury index.

[0027] Furthermore, simulation analysis of the second-row zero-gravity seat occupant restraint system for frontal collisions shows that the structural design of the front seats may pose additional threats to the feet and lower limbs of zero-gravity seat occupants during a collision, further exacerbating the risk of injury to these areas.

[0028] Therefore, although there are already airbags for upper body protection, such as seat cushion airbags, airbags for lower limb protection are still lacking, which undoubtedly increases the risk of lower limb injury for zero-gravity seat occupants in a collision.

[0029] Based on this, the seat of this utility model adds an airbag module to the footrest, which enables the seat to effectively reduce the displacement of the occupant on the seat body when a frontal collision occurs, improve the protection effect of the airbag module on the occupant's lower limbs, and thus reduce occupant injury.

[0030] The following is for reference. Figure 1 Describes a seat according to an embodiment of the present utility model.

[0031] Figure 1 This is a structural schematic diagram of a seat according to an embodiment of the present invention. Figure 1 As shown, the seat 100 includes: a seat body 110, an airbag module 120, and an airbag controller (not shown in the figure).

[0032] Specifically, the seat body 110 includes a seat cushion (not shown in the figure), a backrest (not shown in the figure), and a leg rest 111. The backrest is connected to the rear end of the seat cushion, and the leg rest 111 is connected to the front end of the seat cushion. An airbag module 120 is disposed on the leg rest 111. The airbag module 120 is used to restrict the lower limb movement of the occupant on the seat body 110 after deployment. An airbag controller is electrically connected to the airbag module 120. The airbag controller controls the state of the airbag module 120 based on the received vehicle status signal.

[0033] In an embodiment, such as Figure 1 As shown, the backrest is connected to the rear end of the seat cushion to provide back support for the occupant, while the leg rest 111 is connected to the front end of the seat cushion to provide additional comfort support for the occupant's legs.

[0034] Furthermore, an airbag module 120 is provided on the leg rest 111. The airbag module 120 can be quickly deployed when needed to form a protective barrier to restrict the movement of the occupant's lower limbs in specific situations (such as a vehicle collision), thereby preventing the occupant from moving too far forward due to inertia or suffering unnecessary injury.

[0035] The airbag controller and airbag module 120 communicate and control each other via electrical connection. The airbag controller can receive various status signals from the vehicle, such as whether the footrest 111 is open, whether the backrest angle exceeds the set angle, etc. The airbag controller controls the status of the airbag module 120 according to the vehicle status signals, that is, it quickly and accurately determines whether the airbag module 120 needs to be activated based on the vehicle status signals, so as to ensure the safety of the occupants to the greatest extent.

[0036] For example, when a vehicle collision occurs, the airbag controller can activate the airbag module 120 by receiving the vehicle status signal. The rapidly inflated airbag module 120 provides additional support and restraint for the occupant's lower limbs, effectively reducing the occupant's displacement. Especially under the impact force generated by the collision, the airbag module 120 can respond quickly, slowing down the occupant's forward or lateral movement, thereby reducing the impact injury caused by inertia. This significantly improves the protective effect of the entire occupant restraint system, providing more comprehensive and effective safety protection for the occupant.

[0037] Therefore, the aforementioned seat 100 has an airbag module 120 installed on the footrest 111 of the seat body 110. The airbag module 120 is electrically connected to the airbag controller, allowing the airbag controller to control the state of the airbag module 120 based on the vehicle status signal. When necessary, such as in the event of a vehicle collision, the airbag controller will control the airbag module 120 to deploy rapidly, restricting the movement of the occupant's lower limbs on the seat body 110 and providing solid support and effective restraint for the occupant's lower limbs. This not only effectively reduces the occupant's displacement during a collision but also reduces the impact injury caused by inertia by slowing down the occupant's forward or lateral movement, thereby significantly improving the protective effect of the entire occupant restraint system and providing more comprehensive and effective safety protection for the occupant.

[0038] In one embodiment of the present invention, the airbag module 120 includes: an airbag box, an air bag, and a gas generator, wherein the airbag box is disposed on the leg rest 111; the gas generator and the air bag are disposed inside the airbag box, the air bag is connected to the gas generator, and the gas generator is electrically connected to the airbag controller; after the gas generator is turned on, it inflates the air bag to make the air bag unfold and thereby restrict the movement of the occupant's lower limbs.

[0039] In this embodiment, the airbag box is mounted on the leg rest 111 of the seat body 110, ensuring that the airbag module 120 can quickly and accurately approach the occupant's legs when needed. Meanwhile, the gas generator and airbag are installed inside the airbag box, with the airbag connected to the gas generator, forming a highly efficient inflation system.

[0040] Furthermore, the gas generator is electrically connected to the airbag controller. For example, in the event of a vehicle collision, the airbag controller can quickly identify and trigger the gas generator. Once activated, the gas generator immediately releases gas to inflate the airbag, causing it to expand and fully deploy within a short time. The deployed airbag fits snugly around the occupant's lower limbs, effectively restricting their free movement during a collision, thereby significantly reducing the risk of injury to the occupant's lower limbs from the impact force.

[0041] In one embodiment of this utility model, such as Figure 2 As shown, the air bag includes multiple air columns arranged in sequence, with inflation holes provided between adjacent air columns.

[0042] In this embodiment, the airbag consists of multiple transverse air columns arranged sequentially inside the airbag, with inflation holes between adjacent columns. These inflation holes allow gas to flow freely between the columns when the gas generator releases gas, ensuring that each column inflates evenly and rapidly. This allows the airbag to closely conform to the occupant's leg contours when deployed, providing support and restraint. It also enhances the overall adaptability and flexibility of the airbag, enabling it to more effectively absorb and disperse impact forces in collisions from different directions and angles, further reducing the risk of occupant injury.

[0043] In addition, this air column design provides passengers with some room for movement in their lower limbs, avoiding discomfort or injury caused by excessive restraint, thus ensuring safety while also improving the passenger's riding experience.

[0044] In one embodiment of this utility model, multiple air columns are folded into a fan shape; and / or multiple air columns extend in the left-right direction after unfolding.

[0045] In this embodiment, when the gas generator is not activated, multiple air columns will fold into a fan shape and be stored in the front end and left and right sides of the footrest 111. This not only saves storage space and makes it easier to integrate the air bags into the vehicle's internal structure when not in use, but also ensures that they can be deployed quickly and orderly in an emergency.

[0046] Furthermore, when the gas generator is activated, these folded air columns extend along the left and right sides of the vehicle, covering the critical area of ​​the occupants' legs and providing comprehensive protection. This not only increases the protective area of ​​the airbags but also ensures stable and even support for the occupants in different types of collisions, effectively reducing potential injuries to the lower limbs. Thus, while maintaining efficient space utilization, it significantly improves the level of occupant safety.

[0047] In one embodiment of this utility model, such as Figure 2 As shown, the air bag has flaps on both sides, which are connected to the leg supports.

[0048] In an embodiment, such as Figure 2As shown, the airbag has specially designed flaps on both sides, which connect to the leg rests 111. This connection method not only ensures that the airbag fits securely around the occupant's legs when deployed, preventing displacement or swaying due to sudden events such as vehicle collisions or emergency braking, thus effectively improving the airbag's protective performance; at the same time, the tight connection between the flaps and the leg rests also provides the occupant with a more snug and comfortable riding experience. During normal vehicle operation, the combination of the flaps and leg rests also provides some support, helping to reduce fatigue that may occur during long journeys. Therefore, the airbag not only enhances safety protection but also takes into account the occupant's riding comfort, achieving a perfect blend of safety and comfort.

[0049] In one embodiment of this utility model, the bottom of the air bag is connected to a gas generator, and the top of the air bag is provided with at least one reinforcing member, which is connected to the leg support.

[0050] In this embodiment, the bottom of the airbag is connected to a gas generator, ensuring that when the gas generator receives a trigger signal, it can quickly and accurately inflate the airbag, allowing it to deploy rapidly and smoothly, thus providing an immediate protective barrier for the occupants. Simultaneously, to further enhance the structural stability and durability of the airbag, at least one reinforcing member is provided at the top of the airbag, and this member is tightly and securely connected to the leg support 111. This not only effectively prevents excessive deformation or damage to the airbag during deployment, ensuring its long-term protective performance, but also further enhances the overall stability of the airbag, ensuring it remains in the correct position in extreme situations such as vehicle collisions, providing stable and reliable protection for the occupants.

[0051] In one embodiment of this utility model, such as Figure 1 As shown, there are two reinforcement components, each located at one end of the top of the air bag; and / or, as... Figure 2 As shown, the reinforcement component is a pull strap.

[0052] In an embodiment, such as Figure 1 As shown, the reinforcement components are, for example, bolts. To maximize the structural stability and protective performance of the airbag, a reinforcement component is installed at each of the top two ends of the airbag. This not only evenly distributes the pressure borne by the airbag when it deploys, preventing structural damage caused by excessive force at a single point, but also ensures that the airbag can maintain its shape integrity in a collision accident, providing more uniform and reliable protection for the occupants.

[0053] Furthermore, such as Figure 2As shown, the reinforcement component is a pull strap. With its high strength and flexibility, the pull strap can not only effectively resist external impact and maintain the stability of the airbag, but its flexible installation method also makes it easy to achieve a tight and firm connection with the leg support 111. This further enhances the integration and synergy between the airbag and the vehicle as a whole, thereby improving the safety performance of the airbag and providing more comprehensive and effective protection for the occupants.

[0054] In one embodiment of the present invention, the airbag box is installed at the front end and / or the left and right sides of the leg support 111; and / or the gas generator is configured as a pyrotechnic gas generator.

[0055] In this embodiment, the airbag box is installed at the front end and / or the left and right sides of the leg rest 111. This not only facilitates the rapid deployment of the airbag in an emergency to provide immediate protection for the occupants, but also maximizes space utilization, ensuring a clean and comfortable interior space for the vehicle.

[0056] Furthermore, the gas generator is configured as a pyrotechnic gas generator. This type of generator, with its high efficiency and speed, can produce a large amount of gas in a very short time after receiving a trigger signal, rapidly inflating the airbag and achieving optimal protection. The pyrotechnic gas generator not only has a fast response time but also stable and reliable performance, providing a solid guarantee for the safety of the occupants.

[0057] In one embodiment of the present invention, the airbag controller is configured to control the airbag module 120 to be in an active state when it receives a signal indicating that the leg rest 111 is in an open state and a signal indicating that the backrest angle has reached or exceeded a set angle; and to control the airbag module 120 to deploy when it receives a signal indicating that the airbag is open and the airbag module 120 is in an active state.

[0058] In this embodiment, when the airbag controller receives a vehicle status signal, it can control the activation state of the airbag module 120 based on the vehicle status signal.

[0059] Specifically, when the airbag controller receives a signal indicating that the footrest 111 is in the deployed state (meaning the occupant has adjusted the seat to a more relaxed or resting posture), and a signal indicating that the backrest angle has reached or exceeded a set angle (e.g., 55 degrees, meaning the occupant has adjusted the seat body 110 to a reclined seating mode), the airbag controller will activate the airbag module 120 to a usable, ready-to-use state, providing immediate safety protection for the occupant. At this time, the airbag module 120, along with other airbags in the vehicle, is controlled by the vehicle's airbag controller, forming a comprehensive and coordinated safety protection system.

[0060] Furthermore, for example, when a vehicle encounters a frontal collision and the collision intensity reaches or exceeds the airbag controller's deployment threshold, a signal is sent to the airbag controller to instruct the airbag to deploy, and the airbag module 120 is activated. At this time, the airbag controller controls the airbag module 120 to deploy, and at the same time, the airbag controller also controls other airbags in the vehicle to deploy synchronously, thereby providing maximum protection for the occupants.

[0061] In summary, according to the embodiment of this utility model, the seat 100 has an airbag module 120 on the footrest 111 of the seat body 110. The airbag module 120 is electrically connected to the airbag controller, enabling the airbag controller to control the state of the airbag module 120 based on the vehicle status signal after receiving the signal. When necessary, such as in the event of a vehicle collision, the airbag controller will control the airbag module 120 to deploy rapidly to restrict the movement of the occupant's lower limbs on the seat body 110, providing solid support and effective restraint for the occupant's lower limbs. This not only effectively reduces the occupant's displacement during a collision but also reduces the impact injury caused by inertia by slowing down the occupant's forward or lateral movement, thereby significantly improving the protective effect of the entire occupant restraint system and providing more comprehensive and effective safety protection for the occupant.

[0062] The present invention also proposes a vehicle 200 in the embodiments.

[0063] like Figure 3 The diagram shown is a structural block diagram of a vehicle according to an embodiment of the present invention. The vehicle 200 includes a seat 100 as described in any of the above embodiments of the present invention.

[0064] According to an embodiment of the present invention, a vehicle 200 has an airbag module 120 installed on the footrest 111 of the seat body 110. The airbag module 120 is electrically connected to the airbag controller, enabling the airbag controller to control the state of the airbag module 120 based on the vehicle status signal. When necessary, such as in the event of a collision, the airbag controller will control the airbag module 120 to deploy rapidly to restrict the movement of the occupant's lower limbs on the seat body 110, providing solid support and effective restraint for the occupant's lower limbs. This not only effectively reduces the occupant's displacement during a collision but also reduces the impact injury caused by inertia by slowing down the occupant's forward or lateral movement, thereby significantly improving the protective effect of the entire occupant restraint system and providing more comprehensive and effective safety protection for the occupant.
