[0023] This utility model provides a multifunctional cross-legged footrest chair, which solves the problem that existing chairs have limited functions and cannot adequately accommodate various sitting postures. By adjusting the chair structure, it can be comfortably used for cross-legged sitting, normal sitting, and sitting with legs raised off the ground, thus better meeting the needs of consumers.

[0024] Please see Figures 1 to 5 This utility model discloses a multifunctional cross-legged footrest chair, comprising a seat 3 and a backrest 2 connected together. More specifically, the seat 3 and the backrest 2 are perpendicular or at a specific angle. The seat 3 and the backrest 2 are, for example, integrally formed, directly fixed, or connected by a connector (a chair frame support piece 11 in the illustrated embodiment). The width of the seat 3 is greater than the width of the backrest 2. More specifically, the width of the seat 3 is sufficient to meet the needs of an adult sitting cross-legged, for example, the feet will not dangle outside the seat 3, thus ensuring stability and comfort when sitting cross-legged. The width of the backrest 2 can be selected as the width of a conventional chair to provide back support. Flip-up armrests 1 are rotatably connected to both sides of the backrest 2. When the armrests 1 are in the lowered state... Figure 4 As shown, for example, when lowered to a horizontal position, the user can sit on the seat 3 and rest their arms on the two flip-up armrests 1 on either side. And when the flip-up armrests 1 are flipped up, as... Figure 2 As shown, for example, when folded up to be vertical, the space on both sides of the seat 3 is open, allowing the user to switch to a cross-legged sitting position. A footrest 7, which can extend and retract relative to the bottom of the seat 3, is movably connected to the bottom of the seat 3 via a sliding footrest support 6. The retracted and extended states of the footrest 7 are as follows: Figure 2 , Figure 4 As shown, when the user is in a normal sitting posture with legs crossed or naturally dangling on the ground, the footrest 7 can be adjusted to the retracted state; when the footrest 7 is extended, please refer to... Figure 5 Users can lift their legs or place their legs or feet on the footrest 7 to form another extended sitting posture. The footrest 7 is preferably a soft pad to ensure comfort.

[0025] More specifically, the folding armrest 1 is rotatably connected to the side of the chair back 2 via an armrest pivot, with the pivot located near one end of the folding armrest 1 (intuitively, at one end of the backrest or at the bottom). For example Figure 1 In the illustrated embodiment, the armrest pivot extends inward from the flip armrest 1 and inserts into the corresponding hole on the side of the chair back 2 to form a rotatable connection. Generally, it also has a corresponding limiting structure to prevent the flip armrest 1 from accidentally detaching or falling off. It also includes an armrest limiting mechanism for restricting the rotation of the flip armrest 1 or for positioning the flip armrest 1, thereby ensuring that the flip armrest 1 can be stably maintained in the flipped-up and flipped-down states. For example, the armrest pivot may have damping, or the cross-sectional shape of the armrest pivot may be non-circular and have a specific matching relationship with the shape of the corresponding hole on the side of the chair back 2. Alternatively, there may be matching limiting blocks or latches on the flip armrest 1 and the chair back 2, etc. Based on existing technology, there are many ways to achieve the above-mentioned required functions.

[0026] Please see Figure 2 , Figure 3 Preferably, the flip-up armrest 1, when flipped up, forms an extension section extending outward from both sides of the backrest 2. Specifically, the bottom surface of the flip-up armrest 1 in the lowered state faces forward when flipped up, and matches the shape of both sides of the backrest 2, forming an extension (or expansion) of the front side of the backrest 2. This allows the flip-up armrest 1 and the original backrest 2 to together form a larger backrest, making it easier to sit cross-legged. It is conceivable that, for example, when a user changes their sitting posture, they may need to move left and right or tilt their body significantly. In this case, a larger backrest can provide better support, preventing discomfort caused by the back contacting the edge of the backrest, or instability due to part of the back being suspended from the backrest. Simultaneously, if the fixed backrest is widened directly, the distance between the two flip-up armrests 1 will be too wide, making it unsuitable for a normal sitting posture, or the flip-up armrest 1 will affect the width or comfort of the overall plane or curved surface of the backrest when flipped up. In some embodiments, such as... Figure 3 As shown, the front-facing surfaces of the chair back 2 and the flip-up armrest 1 are both flat; in other embodiments, the front-facing surface of the chair back 2 is curved, for example, having an arc that curves slightly from the left and right sides towards the middle, to provide better support for the back, and the position and structure of the flip-up armrest 1 are adapted to the shape of the chair back 2.

[0027] Please see Figure 1 , Figure 3 , Figure 5Preferably, a footrest sliding support frame 6 is slidably connected to a footrest sliding frame 4, and a footrest 7 is connected to the end of the footrest sliding frame 4, thus forming a sliding and pull-out structure for easy use. More preferably, the footrest 7 is rotatably connected to the footrest sliding frame 4, that is, it can be flipped; and it has a footrest limiting mechanism for limiting the rotation of the footrest 7 or for positioning the footrest 7, so as to ensure that the footrest 7 can stably support the leg or foot when it is extended.

[0028] In a specific embodiment, the footrest sliding frame 4 consists of two or more guide blocks (two in the illustrated embodiment), each guide block having a through guide hole in the front-to-back direction. The footrest sliding frame 4 also consists of sliding rods corresponding to the guide blocks, which are slidably connected in the guide holes, thus forming a sliding connection. The presence of two (or more) guide blocks and correspondingly two (or more) sliding rods ensures smooth extension and retraction of the footrest 7 and that the footrest 7 extends to the same height on both sides. Both ends of the sliding rods have a limiting mechanism to prevent them from dislodging from the guide holes, such as an end cap or other structure that increases the size of the end of the sliding rod, making it larger than the diameter of the guide hole to achieve the desired limiting effect. A crossbar is connected to the end of the sliding rod furthest from the backrest 2. This crossbar allows all the sliding rods to be fixed together, for example, on the same plane. Furthermore, the crossbar is rotatably connected to one side of the bottom of the footrest 7, forming a pivot for the rotation of the footrest 7. The footrest limiting mechanism may have damping at the pivot formed by the crossbar, or the cross-sectional shape of the pivot may be non-circular and have a specific matching relationship with the shape of the corresponding hole in the footrest 7, or there may be matching limiting blocks or latches on the flipping footrest 7 and the footrest sliding frame 4, etc. Based on the existing technology, there are many ways to achieve the above-mentioned required functions.

[0029] This invention's structure, where the footrest 7 slides forward and then flips open further, allows the footrest 7 to be further away from the seat 3 in its extended state, thus better supporting the legs or feet; and preferably, as... Figure 5 As shown, in the extended state, the upper surface of the footrest 7 is slightly lower than the seat 3, corresponding to the slightly bent state of the human leg in a relaxed state, so that the user can comfortably lift and stretch their legs to sit.

[0030] Preferably, a height-adjusting gas spring 8 for adjusting the height of the seat 3 is provided below the seat 3, and the gas spring 8 has a control switch 5. The height-adjusting gas spring, also known as a pneumatic lever, is existing technology. Its upper part is fixedly connected to the bottom surface of the seat 3 via a height-adjusting control support base. The height-adjusting control support base has a control switch 5, such as a lever, which allows for free height adjustment according to the user's height. Furthermore, the lower end of the gas spring 8 is connected to a five-star chair base 9, which has five radially evenly distributed supports. This base structure ensures greater stability of the seat during various sitting postures and posture transitions.

[0031] Furthermore, casters 10, specifically omnidirectional casters, are provided under the five-star base 9 of the chair, allowing the chair to rotate freely and conveniently. Users can easily move forward and backward, left and right, making it more convenient for office and leisure use. Additionally, this invention is preferably a swivel chair, for example, where the gas spring 8 or the connection point between the gas spring 8 and its upper or lower components can rotate horizontally, further improving its flexibility of use.

[0032] In summary, this multifunctional leg-crossing footrest chair features a larger and wider seat compared to ordinary chairs. It also incorporates flip-up armrests connected to the backrest. In a normal sitting position, the armrests can be lowered to support the arms, and flipped up to create open space on both sides of the seat, providing ample room for the user to cross their legs. This ensures freedom and comfort during sitting and posture transitions. Preferably, with the armrests flipped up, they combine with the backrest to form a larger backrest, further enhancing comfort. Furthermore, this invention also considers those who dislike crossing their legs and provides more seating options by incorporating a retractable footrest. For example, it can be convenient to use by being pulled out; preferably, the footrest can be flipped to realize the conversion between storage and extension functions, so as to ensure that the footrest can be stored under the seat in the retracted state without obstructing the legs, while in the extended state the footrest can form a sufficient distance from the backrest, thus accommodating users with different leg lengths; further preferably, it adopts an adjustable height swivel chair type, which is more convenient to use; therefore, the multifunctional cross-legged footrest chair of this utility model can realize the conversion between leisure and office scenarios, completely breaking through the office definition of ordinary chairs, better meeting the consumption upgrade of consumers, improving the comfort of the seat, and providing comfortable support in various sitting postures, which is conducive to the user's physical health.
