[0042] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0043] Embodiment one

[0044] The embodiment relates to a vehicle seat which can be used for passenger lifesaving after the vehicle falls into water.

[0045] In daily actual traffic scene, under the comprehensive influence of vehicle sudden accident, non-standard driving operation method and other unpredictable factors, vehicle falling accident occurs occasionally. When the vehicle unfortunately falls into water, due to the pressure difference inside and outside the vehicle, the door is difficult to be smoothly opened in the conventional way, thereby endangering the safety of the people in the vehicle.

[0046] In the prior art, in response to the situation of a vehicle falling into water, a portable window breaker or a seat headrest rod is used to break the window, so that the occupants can escape from the vehicle. However, this method has a series of limitations in practical application. After the window is broken, the water outside the vehicle with high pressure will quickly and massively flow into the relatively low pressure space inside the vehicle.

[0047] During this process, the vehicle will increase its weight due to the rapid inflow of water, which will accelerate the sinking speed of the vehicle, making the entire emergency escape situation more complex and dangerous. At the same time, the inflowing water will form a turbulent water flow field inside the vehicle, and the environment inside the vehicle will be in a state of extreme chaos. When the occupants try to pass through this water flow field, they will encounter a great resistance, which not only causes a strong impact on the body of the occupants, but also greatly limits their ability to act, making it difficult for the occupants to quickly and smoothly escape from the vehicle through the window.

[0048] Even if the occupants successfully escape from the vehicle after overcoming many difficulties, they will still face a serious survival challenge in the case of a deep water level around the falling site. In areas with relatively poor geographical environment and uneven distribution of rescue resources, such as some remote mountainous areas or rarely visited places, once a vehicle falls into water, external rescue forces will be difficult to arrive at the scene within a specified time due to factors such as distance and poor transportation.

[0049] In this case, the occupants will continuously consume their physical strength while being in a cold and turbulent water flow environment for a long time. At the same time, due to the limitations of human functions and the influence of psychological pressure, the occupants may experience a variety of adverse reactions such as hypothermia, water choking, and panic, which greatly increase the risk of drowning of the occupants.

[0050] Therefore, the present embodiment proposes a new vehicle seat to address the deficiencies in the prior art. And in terms of overall structure, as shown in Figure 1 and Figure 2 , a detachable covering member 11 is provided on the vehicle seat of the present embodiment, and an inflation assembly is provided in the covering member 11. The covering member 11 forms a covering of part of the seat frame of the vehicle seat, and after the covering member 11 is separated from the vehicle seat, the air bag 2 in the inflation assembly can be inflated by the inflation member and expanded to an inflated state.

[0051] At this time, as in the above structure, the use of the detachable covering member 11 and the inflation member provided in the covering member 11 allows the air bag 2 to be inflated to an inflated state after the covering member 11 is separated from the vehicle seat, and the covering member 11 and the air bag 2 together form a floatable life-saving device. This makes it convenient for the occupants to use the life-saving device after the vehicle falls into water and the occupants escape from the vehicle, helping the occupants to escape from the falling site or wait for rescue, thereby providing protection for the life safety of the occupants.

[0052] Based on the overall structure as above, in detail, continue to refer to Figures 1 to 2 As shown, generally speaking, in the structural composition of the vehicle seat, mainly includes the seat framework and the cladding 11 arranged on the seat framework. Among them, the seat framework as the core support structure of the vehicle seat, undertakes the key role of providing stable mechanical properties for the whole seat, which is usually made of high-strength metal material by specific processing technology, to ensure that it can withstand various complex loads during vehicle driving, and protect the safety of passengers.

[0053] And the cladding 11 is the component covering the surface of the seat framework, its main function is not only to improve the overall appearance of the seat, make it coordinate with the vehicle interior style, but also to provide comfortable riding experience for passengers. Generally speaking, the cladding 11 includes cushion cladding 11, backrest cladding 11, headrest cladding 11, etc., and the cladding 11 mostly adopts soft and skin-friendly materials to increase the comfort of riding, such as foam, and the skin covering the foam, etc.

[0054] In this embodiment, the cladding 11 forms the cladding of part of the seat framework in the vehicle seat, and the cladding 11 can be separated from the seat framework. It is worth mentioning here that the cladding 11 can be a cushion cladding arranged on the cushion framework, a backrest cladding arranged on the backrest framework 10 or a headrest cladding. The inflatable assembly is arranged in the cladding 11, which includes an inflatable component and an air bag 2, and the air bag 2 in the inflatable assembly can be inflated by the inflatable component after the cladding 11 is separated from the seat framework, so that the air bag 2 in the compressed state is expanded to the inflated state.

[0055] As a preferred embodiment, in this embodiment, still referring to Figure 1 And Figure 2 And combining Figures 3 to 5 As shown, the cladding 11 is arranged on the backrest in the vehicle seat and forms the cladding of part of the backrest framework 10 of the backrest, which is the backrest cladding 11. This structure can rely on the reasonable layout of the existing structure of the seat backrest to arrange the inflatable assembly, and when the inflatable assembly is arranged in the compressed state on the side of the cladding 11 facing the backrest framework 10, it does not need to occupy additional space, and can ensure that the function of the backrest of the vehicle seat is not affected and the normal use performance is maintained.

[0056] In this embodiment, the inflatable assembly is specifically arranged on the side of the cladding 11 facing the backrest framework 10, between the cladding 11 and the backrest framework 10. Among them, the air bag 2 in the inflatable assembly is preferred, which is fixed on the back side of the cladding, so that the size of the air bag 2 can be set larger, and the arrangement and fixation of the air bag 2 in the compressed state are facilitated.

[0057] In the specific implementation, as a preferred implementation, the air bag 2 and the inflating component in the inflating assembly are adhesively connected on the cladding member 11, and specifically, the air bag 2 and the inflating component are adhesively connected on the foam in the cladding member 11. Such a connection mode, on the one hand, helps to improve the convenience of arranging the inflating assembly on the cladding member 11, and on the other hand, can ensure the reliability of fixing the inflating assembly on the cladding member 11, and compared with the mechanical connection fixing mode such as screwing and clamping, can reduce the overall weight of the cladding member 11, thereby improving the use effect.

[0058] Here, it can be understood that, in addition to the adhesive connection mode, the inflating assembly can also be fixed on the cladding member 11 in other modes, for example, a high-strength woven tape can be used to surround the inflating component, and the woven tape can be fixed on the cladding member 11 by knotting, binding and other modes, and the air bag 2 can be fixed on the cladding member 11 by a magic tape.

[0059] Alternatively, the following mode can also be used, for example, a buckle structure of a specific shape and size is designed on the air bag 2 shell or the inflating component shell, a corresponding clamping groove is arranged on the cladding member 11 at a corresponding position, and the inflating assembly is fixed on the cladding member 11 by clamping and clamping groove clamping cooperation. It should be noted here that, in order to facilitate the arrangement of the clamping groove on the cladding member 11, an installation plate can be fixed on the cladding member 11, and the clamping groove is arranged on the installation plate. In this way, the installation plate arranged can provide a stable arrangement basis for the clamping groove, and can better ensure the stability of the arrangement of the air bag 2 shell or the inflating component on the cladding member 11.

[0060] In order to ensure the connection effect between the cladding member 11 and the backrest framework 10 and facilitate the separation of the cladding member 11 from the backrest framework 10, in the embodiment, a locking structure 13 and an unlocking member 14 are arranged between the cladding member 11 and the backrest framework 10. The locking structure 13 can lock the cladding member 11 on the backrest framework 10, so that the cladding member 11 can be better fixed on the backrest framework 10 to ensure the normal use of the seat backrest. The unlocking member 14 is used to release the locking of the cladding member 11 by the locking structure 13, so that after the locking of the cladding member 11 is released, the cladding member 11 can be smoothly and quickly separated from the backrest framework 10.

[0061] In some possible implementation manners, the locking structure 13 of the embodiment includes a locking buckle arranged on one of the covering member 11 and the backrest framework 10, and a locking hole arranged on the other one of the covering member 11 and the backrest framework 10, and the locking buckle can be clamped in the locking hole when the covering member 11 is wrapped on the backrest framework 10. At this time, the locking structure 13 adopts the form of the locking buckle and the locking hole, and the structure is relatively simple, and the covering member 11 can be locked on the backrest framework 10 through the clamping cooperation of the locking buckle and the locking hole, so as to ensure that the covering member 11 will not fall off during the normal driving of the vehicle, so that the normal use of the seat backrest is ensured, and the passenger riding comfort and the overall stability of the seat are ensured.

[0062] In specific implementation, the locking buckle can be arranged on the covering member 11, and the locking hole is arranged on the backrest framework 10, and the covering member 11 is locked and fixed on the backrest framework 10 through the clamping cooperation of the locking buckle and the locking hole. Of course, it can be understood that the locking buckle can also be arranged on the backrest framework 10, and the locking hole is arranged on the covering member 11 at this time, so that the locking of the covering member 11 and the backrest framework 10 can also be realized through the clamping cooperation of the locking buckle and the locking hole.

[0063] In the embodiment, the unlocking member 14 includes an unlocking pull wire connected with the covering member 11, and the locking buckle can be driven out of the locking hole by pulling the unlocking pull wire. At this time, the unlocking member 14 adopts the unlocking pull wire connected with the covering member 11, and the locking buckle is driven out of the locking hole by pulling the unlocking pull wire, so that the unlocking of the locking structure 13 is facilitated, the convenience of the unlocking operation is improved, and the passenger can quickly separate the covering member 11 from the backrest framework 10 when the covering member 11 needs to be used, so as to provide guarantee for subsequent escape and rescue.

[0064] In specific implementation, the unlocking pull wire can pass through the locking hole, and the locking hole moves relative to the locking buckle when the unlocking pull wire is pulled, so that the locking buckle is separated from the locking hole to unlock the locking structure 13. Of course, the unlocking pull wire can also be connected with the locking buckle, and the locking buckle moves relative to the locking hole when the unlocking pull wire is pulled, so that the locking buckle is separated from the locking hole to unlock the unlocking structure.

[0065] It should be pointed out that, in addition to the above structure, the locking structure 13 and the unlocking member 14 can also adopt other structure forms in the prior art, as long as the locking between the covering member 11 and the backrest framework 10 and the unlocking of the locking structure 13 to the covering member 11 can be realized.

[0066] In this way, in the actual use scene of the vehicle, when the vehicle encounters an emergency, such as accidentally falling into water, the occupant in the vehicle successfully opens the door or window to escape, and needs to quickly obtain a lifesaving tool. At this time, the unlocking piece 14 can be pulled to unlock the covering piece 11 locked by the locking structure 13, and at the same time, the covering piece 11 is separated from the backrest frame 1010, and then the air bag 2 is inflated through the inflating component, so that the covering piece 11 provided with the air bag 2 forms a floating body, helping the occupant to use for lifesaving.

[0067] As a preferred embodiment, as shown in Figure 2 and Figure 4 In this embodiment, the covering piece 11 specifically includes a front portion 111 covering the front side of the backrest frame 10, a side portion 112 covering the left and right sides of the backrest frame 10, and a rear portion 113 covering the top position of the rear side of the backrest frame 10. Among them, the front portion 111, the side portion 112 and the rear portion 113 are connected integrally with each other, and the front portion 111, the side portion 112 and the rear portion 113 jointly form a sleeving cavity 114 for embedding the backrest frame 10.

[0068] Here, in the structure of the covering piece 11, the front portion 111, the side portion 112 and the rear portion 113 are connected integrally with each other, and cover the front side, the left and right sides and the top position of the backrest frame 10 respectively, and the front portion 111, the side portion 112 and the rear portion 113 form the sleeving cavity 114 therebetween. In this way, the sleeving cavity 114 can not only make the covering piece 11 better fit on the backrest frame 10, ensuring the installation effect of the covering piece 11, but also form a larger opening 110 on the rear side of the backrest frame 10. Therefore, when the covering piece 11 is in the unlocking state with the locking structure 13, the covering piece 11 can be easily pulled off from the backrest frame 10, making the disassembly of the covering piece 11 more convenient.

[0069] And in specific implementation, the air bag 2 in the inflating assembly is in a compressed state and is fixedly connected to the front portion 111 of the covering piece 11. The gas cylinder in the inflating assembly can be fixedly connected to the front portion 111 of the covering piece 11, or can be fixedly connected to the inner side of the side portion 112 of the covering piece 11, so as to reasonably utilize the structure of the seat backrest.

[0070] As a further preferred embodiment of the present embodiment, specifically referring to Figure 2As shown in FIG. 1, a rear decorative plate 101 is arranged at the rear side of the backrest framework 10. The edge of the rear decorative plate 101 is connected with the rear portion 113 and the side portions 112 of the covering member 11, and the locking structure 13 is arranged between the covering member 11 and the rear decorative plate 101. At this time, the rear decorative plate 101 arranged at the rear side of the backrest framework 10 is connected with the covering member 11, so that the rear portion of the backrest framework 10 is effectively shielded, thereby ensuring the integrity of the rear portion of the seat backrest and improving the overall appearance quality of the vehicle seat.

[0071] Specifically, the covering member 11 forms a larger "n" shaped opening 110 at the rear side of the backrest framework 10, and the rear decorative plate 101 is arranged at the opening 110 and fixedly connected with the backrest framework 10. Still referring to Figure 2 As shown in FIG. 1, as a feasible embodiment, the edge of the rear decorative plate 101 is connected with the rear portion 113 and the side portions 112 of the covering member 11 through the locking structure 13, that is, the edge of the rear decorative plate 101 is connected with the edge of the "n" shaped opening 110 of the covering member 11 through the locking buckle and the locking hole, so as to lock the covering member 11 on the rear decorative plate 101, that is, to lock the covering member 11 on the backrest framework 10.

[0072] In a specific implementation, the edge of the rear decorative plate 101 and the corresponding position of the edge of the covering member 11 can be provided with a plurality of sets of locking buckles and locking holes arranged at intervals. When the unlocking pull wire is arranged, the unlocking pull wire is connected with the plurality of locking buckles, or the unlocking pull wire is connected with the plurality of locking holes. By pulling the unlocking pull wire, the locking buckles are sequentially pulled out of the corresponding locking holes, so as to release the locking between the covering member 11 and the rear decorative plate 101, that is, to release the locking between the covering member 11 and the backrest framework 10.

[0073] It should be pointed out that the cooperation between the unlocking pull wire and the locking structure 13 can adopt other structure forms besides the above structure form. For example, the covering member 11 and the rear decorative plate 101 can be locked and connected together through the structure of a zipper, and the unlocking zipper is fixedly connected with a pull head. At this time, by pulling the pull wire, the pull head moves to connect or separate the teeth of the zipper, so as to realize the locking and releasing of the covering member 11 and the rear decorative plate 101. In addition, it is also worth pointing out that the free end of the unlocking pull wire can be arranged, for example, to extend to the side of the seat or near the headrest, so as to facilitate the unlocking operation of the occupant in a small space.

[0074] In this embodiment, as a preferred embodiment, the inflating component includes a gas cylinder containing compressed gas, the gas cylinder is connected with the air bag 2, and the gas cylinder is provided with a control valve, the control valve is triggered to open, and the gas cylinder can inflate the air bag 2. In this structure, the inflating component uses a gas cylinder containing compressed gas, so that the control valve on the gas cylinder is triggered to open, and the air bag 2 is quickly inflated, so that the air bag 2 can reach the expected inflation state in a short time.

[0075] Specifically, the gas outlet end of the gas cylinder is provided with a control valve, and the gas storage end of the gas cylinder is also connected with the gas inlet end of the air bag 2, so that when the control valve is triggered to open, the gas outlet end and the gas inlet end are in communication, and the gas cylinder inflates the air bag 2. In specific implementation, the gas cylinder group is made of aviation-grade aluminum alloy material, and is filled with inert compressed gas after drying treatment, for example, nitrogen or argon with a purity of ≥99.99%. The gas has the characteristics of chemical stability, non-flammability, low thermal expansion coefficient, etc., which can ensure the safe operation of the system in the environment temperature range of-40℃ to +85℃.

[0076] The control valve adopts a mechanical trigger structure, which can be a trigger pull ring provided on the control valve in the prior art. After the cover 11 is separated from the seat framework, the control valve is opened by manually pulling the trigger pull ring, and at this time, the gas cylinder quickly inflates the air bag 2. The trigger pull ring is designed to have an operating force within a reasonable range, which ensures that the operator can easily pull it in an emergency, and avoids accidental opening of the control valve due to misoperation. The surface of the trigger pull ring can be specially treated to have good anti-slip performance, which ensures stable operation under various environmental conditions.

[0077] In order to further improve the safety and reliability of the inflating assembly, some auxiliary devices can also be provided on the control valve. For example, a safety pin is provided, which can prevent the trigger pull ring from being pulled by mistake under normal circumstances. Only when the system needs to be started, the operator pulls the trigger pull ring after pulling out the safety pin, so as to open the control valve. This double safety design can effectively avoid the misoperation of the system, and ensure that the entire inflating system can work stably and reliably under various complex environments.

[0078] The vehicle seat of the embodiment uses the separable cover 11 provided on the seat and the inflating assembly provided in the cover 11, so that after the cover 11 is separated, the air bag 2 is inflated to the inflation state, and the cover 11 and the air bag 2 form a floatable lifesaving device together. This is convenient for the passenger to use lifesaving after the vehicle sinks and the passenger escapes from the vehicle, helps the passenger to escape from the sinking site or wait for rescue, so as to provide protection for the life safety of the passenger.

[0079] Embodiment two

[0080] The embodiment relates to a vehicle provided with the vehicle seat of the first embodiment.

[0081] Since most of the current vehicles are provided with double-layer laminated glass, compared with the single-layer glass of the sunroof glass 100, the double-layer laminated glass has stronger impact resistance, at this time, it is difficult to open the vehicle window by using the traditional window breaker or the seat headrest rod.

[0082] Therefore, as a preferred embodiment, the vehicle of the embodiment is provided with a sunroof, that is, the embodiment is preferably applicable to the vehicle provided with the sunroof. And the vehicle is also provided with the window breaking device 3 for breaking the sunroof glass 100 at the sunroof. At this time, the window breaking device 3 is arranged, which is beneficial to the passenger to break the sunroof glass 100 at the sunroof, so that the passenger can quickly leave the vehicle from the sunroof, and the passenger can escape from the sinking site or wait for rescue by means of the floating body formed by the cover 11 and the air bag 2.

[0083] In addition, after the vehicle sinks, the control system of the vehicle is powered off, so that the electrically controlled components cannot be used. Therefore, the window breaking device 3 of the embodiment adopts a mechanical structure, for example, the window breaking device 3 can be arranged at the position close to the sunroof glass 100 on the top of the vehicle, as shown in the prior art. Figure 6 And the window breaking device 3 can adopt the structure in the prior art, that is, the window breaking device 3 includes a window breaker, a rotating wheel arranged on the top of the vehicle and a trigger switch, and a pull line wound on the rotating wheel. One end of the pull line is connected with the trigger switch, and the other end of the pull line is connected with the window breaker. At this time, the window breaker can move towards the sunroof glass 100 by pulling the pull line, and the sunroof glass 100 is broken, so that the sunroof position forms a channel for the passenger to escape from the vehicle.

[0084] It should be noted that, in addition to being arranged at the position close to the sunroof glass 100 on the top of the vehicle, the window breaking device 3 can also be arranged beside the handle on the inner side of the door, the side of the seat or other positions convenient for taking, like the structure in the prior art. Of course, it can be understood that, in addition to the mechanical window breaker, the window breaking device 3 can also use the headrest support rod integrated on the headrest.

[0085] Specific use, after the vehicle falls into the water, first passengers should first disassembled headrest, then use the broken window device 3 to break the sunroof glass 100, then operate the unlocking piece 14, remove the locking between the covering piece 11 and the backrest skeleton 10, and pull the covering piece 11 from the backrest skeleton 10 in the upward direction. After the covering piece 11 is separated from the backrest skeleton 10, the control valve is triggered manually to open, so that the compressed gas in the gas cylinder is quickly filled into the air bag 2, and the air bag 2 in the inflated state and the covering piece 11 are formed into a floatable lifesaving device. Then carry the floating body formed by the air bag 2 and the covering piece 11, and escape through the sunroof position to the outside of the vehicle, and then use the floating body to escape from the sinking site or wait to be rescued.

[0086] It is worth noting that for the small size of the sunroof, the air bag 2 in the covering piece 11 can be quickly inflated after escaping from the vehicle, so as to facilitate the covering piece 11 from the sunroof to the outside of the vehicle. In addition, during the waiting process of professional rescue personnel, the covering piece 11 provided with the inflating assembly on the seat can delay the sinking speed of the vehicle to a certain extent in the inflated and expanded state of the air bag 2, so as to gain more time for members to escape, and also can provide necessary buoyancy and certain protection for the vehicle personnel, maintain their vital signs, increase the survival probability in harsh environment, and reduce the possibility of casualties caused by long-time waiting for rescue.

[0087] The vehicle of the embodiment can form a floatable lifesaving device by using the separated covering piece 11 of the vehicle seat of the first embodiment, so that the passengers can use the lifesaving device after the vehicle falls into the water and the passengers escape from the vehicle, which can help the passengers to escape from the sinking site or wait to be rescued, thereby improving the safety of the vehicle in special emergency situations.

[0088] The above only describes the preferred embodiments of the present application, and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
