[0040] Next, the embodiments of this specification are described in detail.

[0041] Reference Figure 1-2 As shown, the present application discloses a seat, which includes a base 10 and a seat frame 20. The seat frame 20 is mounted on the base 10, and universal mounting openings 21 are respectively provided on both sides of the seat frame 20. The universal mounting openings 21 can be equipped with different functional connectors to be installed on the seat frame 20. The specific structures of the two optional functional connectors on the seat frame 20 are described below.

[0042] The functional connector 30 includes a mounting plate 31 and a functional plate 32. The functional plate 32 is bent and extended from the mounting plate 31, and the mounting plate 31 is fixed to the universal mounting opening 21. Specifically, the mounting plate 31 is provided with a mounting hole 311 corresponding to the universal mounting opening 21, and the universal mounting opening 21 and the mounting hole 311 are locked by fasteners.

[0043] The universal mounting opening 21 is arranged at the bottom of the seat frame 20, the mounting plate 31 is abutted against the lower surface of the seat frame 20, and the mounting hole 311 and the universal mounting opening are fixedly connected by a screw. Of course, the universal mounting opening 21 can also be arranged on the side or upper part of the seat frame 20.

[0044] The function board 32 is provided with a limit portion 321, which includes a longitudinal depression arranged along the front-rear direction of the function board 32. The corresponding seat also includes an armrest connector 40, on which a support member 41 is provided, and the support member 41 can slide along the limit portion 321.

[0045] Ginseng Figure 3-4 Another optional functional connector 30' of the seat is shown, which includes a mounting plate 31', a functional plate 32' and a connecting plate 33', wherein the connecting plate 33' and the functional plate 32' are respectively arranged on both sides of the mounting plate 31' and are respectively bent and extended from the mounting plate 31', and the mounting plate 31' is fixed to the universal mounting opening 21. Specifically, a mounting hole 311' corresponding to the universal mounting opening 21 is provided on the mounting plate 31, and the universal mounting opening 21 and the mounting hole 311' are locked by fasteners.

[0046] The universal mounting opening 21 is arranged at the bottom of the seat frame 20, and the mounting plate 31 is attached to the lower surface of the seat frame 20. The mounting hole 311' and the universal mounting opening 21 are fixedly connected by screws. In addition, a limiting portion 321' is arranged on the function plate 32', and the limiting portion 321' is a longitudinal depression arranged along the front-rear direction of the function plate 32', and the support member 41 can slide along the limiting portion 321'.

[0047] The footrest assembly 50 can be assembled on the functional connector 30', that is, when the seat needs to be equipped with a footrest function, the functional connector 30' needs to be used to install the footrest assembly 50. The footrest assembly 50 includes a support rod 51 and a footrest 52. A first fixing portion 322' is provided on the functional plate 32', and the support rod 51 is passed through the first fixing portion 322'. At the same time, a second fixing portion 331' is provided on the connecting plate 33', and the support rod 51 is passed through the first fixing portion 322' and the second fixing portion 331'. Of course, the support rod 51 can also be passed through the first fixing portion 322' or the second fixing portion 331' alone. The first fixing portion 322' and the second fixing portion 331' are through holes, and the first fixing portion 322' is arranged on the rear side of the functional plate 32' and is located below the limiting portion 321'.

[0048] Reference Figure 4 As shown, in this embodiment, the footrest 52 is a multi-link mechanism, which includes at least a first link 521 and a second link 522. The first link 521 is rotatably mounted on the support rod 51, and the second link 522 is rotatably mounted on the connecting plate 33'. In this way, the footrest 52 can extend from the bottom to provide foot support for the user. In addition, since the first links 521 of the left and right footrests 52 are connected to the same support rod 51, the synchronous movement of the left and right footrests 52 can be achieved.

[0049] The position-limiting portion 321' is tilted backward from top to bottom, and the corresponding seat frame 20 is also tilted backward from top to bottom. In this way, the seat frame 20 can be easily moved forward and backward under its own gravity and external gravity. In addition, the front end size of the functional board 32' is smaller than the rear end size, which can reduce weight and avoid other components.

[0050] The present application provides a universal installation port 21 on the seat frame 20, thereby enabling different functional connectors to be installed on the seat frame 20, providing customized seating to meet the personalized needs of different consumers and making the seating more competitive.

[0051] Reference Figure 1 and Figure 4As shown, the seat frame 20 includes a front frame 22 and a rear frame 23. The seat also includes an adjustment device 70, which is installed between the front frame 22 and the rear frame 23 so that the front frame 22 can rotate relative to the rear frame 23. In this way, the seat frame 20 is decomposed into the front frame 22 and the rear frame 23, and the rear frame 23 can rotate relative to the rear frame 23 through the adjustment device 70 to meet the different height requirements of users.

[0052] The front frame 22 includes a front beam 221 and a pair of first side beams 222 located on both sides of the front beam 221. The rear frame 23 includes a rear beam 231 and a pair of second side beams 232 located on both sides of the rear beam 231. The front frame 22 and the rear frame 23 together form a U-shaped closed frame body.

[0053] The front beam 221 and the rear beam 231 are arc-shaped structures with openings upward. In this way, the front beam 221 and the rear beam 231 are covered with more fillers, which are softer when touched by users, thereby improving the user experience. The front beam 221, the first side beam 222, the rear beam 231 and the second side beam 232 are square tube structures, and the square tubes are hollow structures. In this way, the overall weight of the seat can be reduced.

[0054] The rear frame 23 is arranged in an inclined shape, wherein the front end height of the rear frame 23 is higher than the rear end height of the rear frame 23. In this way, the rear frame 23 is convenient to move backwards when subjected to its own gravity and the user's thrust, so that the seat is switched from a sitting position to a lying position. The length of the second side beam 232 is greater than the length of the first side beam 222. In this way, the adjustment section of the seat frame 20 is arranged at the front end, which can better adapt to the support height of the legs.

[0055] The front frame 22 can rotate up and down relative to the rear frame 23. The front frame 22 has a first position and a second position, the first position is located above the second position, and the front frame 22 has a plurality of adjustment positions between the first position and the second position. In this way, the user can lock at any position between the first position and the second position according to the actual height, and the adjustment is flexible.

[0056] The front beam 221 and the first side beam 222 form a first support surface, the rear beam 231 and the second side beam 232 form a second support surface, and the first support surface and the second support surface together form a seat support surface. When the front frame 22 is located at the first position, the first support surface and the second support surface are flush; in the first position, the first side beam 222 and the second side beam 232 located on the same side are located on the same straight line. When the front frame 22 is located at other positions, the first support surface and the second support surface are set at an angle.

[0057] Reference Figure 5As shown, the adjusting device 70 includes a rotating member 72, a matching member 71 and an adjusting member (not shown in the figure), the rotating member 72 is arranged at the rear end of the first side beam 222, and the matching member 71 is arranged at the front end of the second side beam 232; the rotating member 72 and the matching member 71 are rotated and matched through the adjusting member. In this embodiment, the adjusting member is a ratchet structure. In this way, the locking position of the front frame 22 between the first position and the second position can be more stable to avoid shaking.

[0058] The front frame 22 can be rotated to the upper part of the first position, the adjusting device 70 is in the unlocked state, and the front frame 22 can be returned to the second position. Of course, an additional unlocking device can also be provided, so that the user does not need to rotate it to the upper part of the first position to unlock it.

[0059] Reference Figure 2 As shown, in this embodiment, the seat frame also includes a base 10 and a crossbar 11, and the crossbar 11 is mounted on the base 10, for example, it can be connected by threads, so as to facilitate disassembly and transportation. In addition, the handrail connector 40 is fixed at both ends of the crossbar 11, for example, the handrail connector 40 and the crossbar 11 are integrally formed to improve the connection stability between the two.

[0060] The seat also includes a backrest assembly 60 , which is rotatably mounted on the rear frame 23 via a backrest connector 61 .

[0061] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
