[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," and "abutting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] The following is based on the appendix Figure 1 To be continued Figure 3 This invention introduces the full-back comfort system and seat provided by this utility model.

[0032] like Figure 1 , Figure 2 As shown, in this embodiment, the full backrest comfort system mainly includes a frame assembly, a lifting assembly, and a drive assembly. The frame assembly is disposed between the seat frame and the seat foam layer, and serves to support and fix the lifting assembly and the drive assembly. The full backrest comfort system includes at least one lifting assembly mounted on the frame assembly. The lifting assembly includes a cable 21 and a connector 22. The connector 22 is disposed at the end of the lifting assembly away from the frame assembly and is fixedly connected to the seat frame, etc. The connector 22 is driveably connected to one end of the cable 21. The drive assembly is mounted on the frame assembly and includes a motor 31. The motor 31 is driveably connected to the other end of the cable 21 and can drive the frame assembly to move towards or away from the connector 22 in a direction perpendicular to the frame assembly via the cable 21.

[0033] In use, for example, when the motor 31 drives the frame assembly to move in a direction close to the connector 22 via the pull cord 21, the frame assembly rises (the seat foam layer also rises), applying greater resistance to the occupant's back, providing stronger support and a firmer seating feel. Conversely, when the motor 31 drives the frame assembly to move in a direction away from the connector 22, the frame assembly retracts under the action of elastic elements such as the seat foam layer, reducing the resistance to the occupant's back, weakening the support, and making the seating feel softer. Of course, when the motor 31 causes the frame assembly to reciprocate in directions close to and away from the connector 22, a massage effect can be achieved.

[0034] The aforementioned full back comfort system can raise and lower the entire frame assembly through the drive and lifting components, changing the support strength for the occupant's back and the firmness of the seating feel with a relatively simple structure. At the same time, the alternating raising and lowering motion can also achieve a massage effect, thereby improving the riding experience of drivers and passengers and delaying the fatigue caused by long-term driving.

[0035] Specifically, in this embodiment, such as Figure 1 As shown, the frame assembly includes a first frame 11 and a second frame 12. The second frame 12 is fixedly connected to the lower end of the first frame 11, and the lifting component is connected to the first frame 11. The first frame 11 is preferably supported by elastic steel wire, possessing a certain elastic deformation capability, which can both fix other components and provide flexible support for the back. The second frame 12 has high rigidity and can firmly fix the motor 31. The second frame 12 and the first frame 11 are fixedly installed together by metal coil nails 13, thus enabling the whole assembly to move.

[0036] More specifically, the drive assembly also includes a reel 33 and a shaft 32. The shaft 32 is driveably connected to the motor 31 and can rotate under the drive of the motor 31. The reel 33 is connected to the shaft 32 and fixedly connected to the pull cable 21. The motor 31 can drive the reel 33 to rotate via the shaft 32, so that the pull cable 21 is wound around the reel 33 or released from the reel 33. For example, the motor 31 can drive the reel 33 to rotate in the forward direction, so that the pull cable 21 is wound around the reel 33, thereby driving the frame assembly to move in a direction close to the connector 22. When the reel 33 rotates in the reverse direction, part of the pull cable 21 wound around the reel 33 is released, and under its own weight and the pressure of the occupants, the frame assembly will move in a direction away from the connector 22.

[0037] More specifically, in this embodiment, such as Figure 2 As shown, the lifting assembly also includes a conduit 23 and a mounting member 24. The pull cable 21 is movably threaded through the conduit 23 to prevent interference or entanglement between the pull cable 21 and other structures within the seat (such as the foam layer). The mounting member 24 is installed at the end of the conduit 23 away from the motor 31 and can be fixedly connected to the first frame 11, thereby fixing the conduit 23 and allowing it to move with the frame assembly as a whole. Optionally, a shaft tube is also provided on the outer side of the rotating shaft 32 to prevent interference or entanglement between the rotating shaft 32 and other structures within the seat (such as the foam layer).

[0038] Continue to refer to Figure 1 , Figure 2 As shown, in this embodiment, the full back comfort system includes at least two lifting components. The pivot 32 is arranged along the central axis of the seat, and at least one lifting component is symmetrically arranged on opposite sides of the pivot 32, thereby achieving a more symmetrical lifting effect and improving the wrapping and comfort after lifting.

[0039] Preferably, at least two rollers 33 are arranged on the rotating shaft 32 along its axial direction, and a lifting component is symmetrically connected to both sides of each roller 33. For example, in this embodiment, four rollers 33 are arranged on the flexible shaft, and two lifting components are symmetrically connected to each roller 33. Thus, by increasing the number of rollers 33 and lifting components along the axial direction of the rotating shaft 32, a better fit to the spine can be achieved, conveniently supporting and massaging the entire back. For example, in this embodiment, along the axial direction of the rotating shaft 32, the lifting component near one end of the rotating shaft 32 provides support for the lower back of the first frame 11, the lifting component near the other end of the rotating shaft 32 provides support for the shoulders of the top of the first frame 11, and the lifting component between the two ends provides support for the portion of the first frame 11 supporting the lower back and shoulders.

[0040] Reference Figure 2 As shown, in this embodiment, a spool 33 has two take-up grooves 331. The two take-up grooves 331 are used to respectively receive the pull lines 21 of the two symmetrically arranged lifting components. The spool 33 has two take-up grooves 331 with the same outline, so that the two symmetrically arranged lifting components can lift the first frame 11 synchronously and with the same amplitude, thereby achieving a better sense of wrapping and comfort.

[0041] Preferably, along the axial direction of the rotating shaft 32, the two reels 33 have take-up grooves 331 with different profiles, so that one set of pull lines 21 (i.e., the pull lines 21 in the two symmetrically arranged lifting components) and the other set of pull lines 21 have different take-up speeds. This allows different positions on the first frame 11 to be lifted at different amplitudes, creating a more adaptable and comfortable fit to the shape of the back and the curve of the spine. Of course, in this case, the rotating shaft 32 is preferably a flexible shaft that can be bent, and the first frame 11 is preferably made of elastic steel wire. The aforementioned tubes 23 and shaft tubes are also made of elastic materials, so that the first frame 11 can deform and conform to the shape of the back and the curve of the spine.

[0042] Optionally, one end of the rotating shaft 32 is connected to the motor 31, and the other end of the rotating shaft 32 is connected to an end fixing member 34. The end fixing member 34 is used to rotatably connect the rotating shaft 32 to the frame assembly, maintain the axial tensile force of the rotating shaft 32, and prevent the rotating shaft 32 from tangling or other malfunctions.

[0043] Furthermore, in this embodiment, the full back comfort system also includes an electronic control unit. The electronic control unit is connected to the motor 31 and can control the motor 31 to rotate in the forward and reverse directions, thereby controlling the lifting-retracting action.

[0044] This utility model also provides a seat including the aforementioned full-back comfort system. The full-back comfort system is disposed between the seat frame and the seat foam layer, and can lift the seat foam layer to conform to the occupant's back, thereby changing the support intensity for the occupant's entire back and the perceived firmness of the seating. Simultaneously, the alternating lifting and retraction motion also achieves a massage effect, thereby improving the riding experience of drivers and passengers and delaying fatigue caused by long-distance driving.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
