Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a vehicle seat and a vehicle equipped with the vehicle seat. Background Technology

[0002] A seat leg rest is a component integrated into the front of the seat cushion to provide support for the passenger's legs. With the continuous innovation and improvement of automotive intelligence and technology, car seat configurations have increased from the initial 2-way and 4-way adjustment to 20-way and even 30-way adjustment, and integrated seat functions have expanded to include television, ventilation, massage, music, and more. Besides hardware configurations, soft features such as ride comfort are also crucial performance indicators; therefore, zero-gravity seats and long leg rests are gradually becoming standard features in cars.

[0003] Currently, all zero-gravity seats and long leg rest designs focus on improving support for the calves, however, as Figure 1 , Figure 2 and Figure 3 As shown, regardless of whether the passenger is sitting, lying down, or only supporting their lower legs, their thighs and popliteal fossa (the area where the thigh and lower leg connect, opposite the knee) are suspended in the air (see area K in the figure), resulting in insufficient support. Utility Model Content

[0047] This application discloses a vehicle seat and a vehicle, which solves the problem of the front of the thigh being suspended near the occupant's popliteal fossa when the leg rest in the vehicle seat is opened.

[0048] First, it should be noted that the occupant referred to in this application is a person or mannequin sitting in the vehicle seat in a normal sitting or lying position.

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Please see Figure 4 The vehicle seat provided in this application includes a backrest 1, a seat body 2, and a leg rest 3 connected in sequence. The leg rest 3 is located at the end of the seat body 2 away from the backrest 1, and is used to support the occupant's lower legs and can be tilted up and down relative to the seat body 2. Furthermore, the vehicle seat also includes a support assembly 4 that supports the occupant's knees. The support assembly 4 is located at the connection between the seat body 2 and the leg rest 3, close to the knees of the occupant sitting on the seat. The height of the support assembly 4 protruding outward relative to the connection is adjustable. That is, when an occupant is sitting on the vehicle seat, the support assembly 4 is substantially directly opposite or substantially located in the occupant's knees. Adjusting the protrusion height of the support assembly 4 adjusts the support for the occupant's knees. It should be noted that the connection between the seat body 2 and the leg rest 3 mentioned in this application refers to any one or a combination of the following: the end region of the seat body 2 near the leg rest 3, the end region of the leg rest 3 near the seat body 2, and the connection area between the seat body 2 and the leg rest 3.

[0051] As can be seen, the vehicle seat provided in this application is suitable for zero-gravity seats and long leg rest designs. It can provide support for the occupant's lower legs through the leg rest 3, and also provide support for the occupant's popliteal fossa (i.e., the front of the thigh below the knee) through the support component 4, preventing the occupant's thighs from dangling. See details... Figure 4 , Figure 5 and Figure 6 Whether sitting, lying down, or simply supporting the lower legs, the support component 4 provides excellent support for the front of the passenger's thighs in the popliteal fossa, preventing problems such as insufficient support and poor comfort caused by the thighs being suspended in the air.

[0052] In some embodiments, the support assembly 4 includes a bag with an adjustable volume and a built-in filling medium, which can be either gas or liquid. When the filling medium includes gas, the bag of the support assembly 4 is connected to an air pump 6 via a gas delivery pipe 5, as detailed in [reference needed]. Figure 4 and Figure 12 When the filling medium includes liquid, the bag of support assembly 4 is connected to the hydraulic pump via a liquid delivery pipe. In practice, the bag of support assembly 4 can be integrated into the seat for convenient use.

[0053] In specific implementation, the bag body of the support assembly 4 can be set as an integral large air bag. In this case, the bag body of the support assembly 4 can be a strip extending along the left and right direction of the seat body 2 (which is also the left and right direction of the occupant sitting on the seat), providing seamless support for the occupant's legs. Moreover, in some embodiments, such as Figure 4 As shown, when the bag of the support assembly 4 is fully filled with internal filling medium, the top surface of the bag is an arc-shaped convex surface, and / or, in the height direction L of the outward protrusion relative to the connection between the seat 2 and the leg rest 3, the width of the bag gradually increases and then gradually decreases in the direction from the seat 2 to the leg rest 3. This allows the top of the support assembly 4 to fit snugly against the occupant's popliteal fossa, ensuring good support comfort. However, this is not the only option. In other embodiments, in addition to the multiple bag units mentioned above, the bag of the support assembly 4 can also be a split structure composed of multiple bag units. Each bag unit can be designed as a small circular bag or other shapes, so that the air bag's protrusion height / number of layers / arrangement and other parameters can be determined according to the space required for support. Passengers can operate the inflation button to inflate and deflate the air and adjust the inflation height as needed, while also providing a massage effect to relieve fatigue caused by long-term sitting.

[0054] The following is a detailed explanation using the example of multiple bag units combined to form support assembly 4.

[0055] In some embodiments, the support assembly 4 includes a plurality of first bag units: the plurality of first bag units are stacked in a height direction L that protrudes outward from the connection between the seat 2 and the leg rest 3. This height direction L can be the direction of protrusion relative to the upper surface of the seat 2, or it can be the direction closer to the popliteal fossa of the occupant sitting on the seat relative to the connection between the seat 2 and the leg rest 3. This stacked bag structure allows the support assembly 4 to have a more stable support shape and a higher support height, and also facilitates control over the filling sequence of the plurality of first bag units. Preferably, the bottommost first bag unit is connected to the air supply pipe 5. When the filling medium is supplied to the bag through the air pump 6 and the air supply pipe 5, the plurality of first bag units bulge sequentially from bottom to top.

[0056] In some embodiments, multiple first bag units are connected sequentially, or the volume of the filling medium in each first bag unit is adjustable. When the filling medium is gas, the multiple first bag units are connected to the air pump 6 through multiple gas supply pipes 5. In this case, the multiple first bag units can correspond one-to-one with the multiple gas supply pipes 5, and each gas supply pipe 5 is controlled to open and close by a valve, so that the volume of each first bag unit can be adjusted independently. Alternatively, in some embodiments, the volume of the filling medium in the multiple first bag units can be grouped and adjustable. When the filling medium is gas, the multiple first bag units can be divided into multiple groups, each group of first bag units including one or more first bag units, and each group of first bag units is connected to the air pump 6 through a gas supply pipe 5, and each gas supply pipe 5 is controlled to open and close by a valve, so that the volume of each group of first bag units can be adjusted independently.

[0057] In some embodiments, two or more second bag units are arranged sequentially along the length of the connection between the seat 2 and the leg rest 3 (which is also the left-right direction of the occupant's knees while seated). Furthermore, the multiple second bag units are sequentially connected, or the volume of the filling medium in each second bag unit is individually adjustable, or the volume of the filling medium in the multiple second bag units is adjustable in groups. And / or, in some embodiments, two or more rows of third bag units are arranged side-by-side in the direction from the seat 2 to the leg rest 3. Furthermore, the two or more rows of third bag units are sequentially connected, or the volume of the filling medium in each row of third bag units is individually adjustable, or the volume of the filling medium in the two or more rows of third bag units is adjustable in groups. The multiple second bag units and the multiple third bag units can also be adjusted independently or in groups. When the filling medium is liquid, the connection method of its infusion pipeline can be the same as that of the gas infusion pipeline described above, and will not be repeated here.

[0058] Furthermore, in some embodiments, the aforementioned vehicle seat is also equipped with a heating component for heating gases or liquids to provide warmth to occupants in cold weather. Moreover, as... Figure 13 As shown, the aforementioned vehicle seat is also equipped with a seat massage system 8.

[0059] In some embodiments, the support assembly 4 can also be height-adjusted using a mechanical transmission method. In this case, the support assembly 4 includes a support portion, a transmission connection portion, and a control portion. Specifically: the support portion supports the occupant's popliteal fossa; the transmission connection portion can be any one or more combinations of transmission mechanisms such as gear racks, ball screws, lever mechanisms, and linear motors, capable of driving the support portion to extend and retract in directions approaching and away from the popliteal fossa; the control portion includes a manual control portion 7 and / or an automatic control portion, used to control the operation of the transmission connection portion. The manual control unit 7 can be any one or more combinations of a knob, lever, button, or voice receiver; the automatic control unit can be an intelligent control mechanism with automatic control. For example, when the leg rest 3 flips upward to support the occupant's outstretched lower leg, the automatic control unit automatically controls the transmission connection to start, so that the support part extends towards the occupant's popliteal fossa until it provides support for the occupant's popliteal fossa; when the leg rest 3 flips downward to allow the occupant to lower their outstretched lower leg, the automatic control unit automatically controls the transmission connection to move, so that the support part retracts away from the occupant's popliteal fossa until it is flush with or nearly flush with the upper surface of the seat and / or the leg rest.

[0060] In some embodiments, the support assembly 4 may also employ a pad structure. Specifically: the support assembly 4 has only one pad, which is detachably connected to the connection between the seat 2 and the leg rest 3; that is, the upper surface of the end region of the seat 2 near the leg rest 3 is detachably connected to the pad, and / or, the upper surface of the end region of the leg rest 3 near the seat 2 is detachably connected to the pad, and / or, the upper surface of the connection area between the seat 2 and the leg rest 3 is detachably connected to the pad. Alternatively, the support assembly 4 may include multiple pads, which can be stacked sequentially along the direction close to the popliteal fossa; at least one pad is detachably connected to the connection between the seat 2 and the leg rest 3, and adjacent pads are detachably connected to each other.

[0061] In some embodiments, the connection between the seat 2 and the leg rest 3 includes a frame and foam located on the upper side of the frame. According to commonly used back massage solutions in the market today, the bag of the support component 4 can be located within the upper groove of the foam, or the bag of the support component 4 can be positioned between the frame and the foam. Specifically, fixing the bag of the support component 4 to the upper end of the foam is called the A-side bag. This type of bag provides a more direct and powerful ejection force. Alternatively, the bag can be fixed to the lower end of the foam, above the frame structure, and is called the B-side bag. This type of bag does not affect the foam thickness, has fewer shape limitations, and a larger ejection area. The A-side bag can be fixed to the groove on the front of the foam using double-sided adhesive. The air supply pipe 5 extends from the foam to the lower end and connects to the air pump 6 fixed to the frame structure. The B-side bag is placed between the foam and the leg rest frame. The air supply pipe 5 is also arranged at the lower end of the foam and connects to the air pump, which is also fixed to the frame.

[0062] In practical implementation, the backrest 1 of the aforementioned vehicle seat can be tilted and adjusted relative to the seat body 2. Furthermore, in addition to the support assembly 4 located at the front end of the seat body 2 to provide support for the front of the thighs, the aforementioned vehicle seat can also provide sequentially arranged massage airbags on the surface of the leg rest 3 to provide massage and relaxation for the calves. See [link to details]. Figure 10 and Figure 11 The surface of the leg rest 3 can be provided with multiple rows of massage air bags. The inflation and deflation of the multiple massage air bags can be controlled independently, or they can be controlled in groups.

[0063] This application also provides a vehicle equipped with the vehicle seat described above.

[0064] In summary, the automotive seats and vehicles provided in this application can improve in terms of parameter configuration and comfort experience, increase the sense of luxury, and provide a new track in the current situation where there is no room for improvement in automotive configuration.
