Description

Technical Field

[0001] This invention relates to the field of seating technology, and more particularly to a seat with a movable seat surface. Background Technology

[0002] Chairs are essential for daily life and work. Currently, various styles of chairs are available on the market, such as ergonomic chairs and gaming chairs, to meet people's needs in terms of backrests, headrests, seat cushions, and armrests. Many office workers and students often need to sit for long periods due to work requirements. This sedentary behavior can lead to problems such as lower back pain, reduced intestinal motility, and constipation. The World Health Organization has listed sedentary lifestyles as one of the top ten causes of sudden death in young adults. How to reduce the harmful effects of prolonged sitting, such as lower back pain, through simple methods is an urgent problem to be solved.

[0003] Intermittent activity can relieve muscle tension caused by prolonged sitting and promote abdominal movement. However, due to work and other limitations, intermittent exercise is difficult to achieve. If the chair seat could move while seated, the harm of prolonged sitting could be reduced without affecting work or study. For example, utility model patent CN210989231U discloses a chair and its rocking support structure, including a tray support and a seat plate set above the tray support, and a rocking component set between the two. The rocking component allows the seat plate to swing in multiple directions relative to the tray support, thereby relieving the discomfort of prolonged sitting. Patent CN109431138A discloses a chair that can rock in any direction, including a seat, a footrest, and longitudinal and transverse restraint devices. The longitudinal and transverse restraint devices are provided with a slide rail frame and a slider, which cooperate with a universal rod set at the center of the footrest, allowing the seat plate to swing in any direction and reduce the harm of prolonged sitting. However, both of these designs are relatively complex and not easy to design and implement. Summary of the Invention

[0004] To address the shortcomings of existing chairs that cannot swing in all directions during use, this invention provides a chair with a movable seat surface. This chair allows the user's torso to swing in either a sitting or reclining position, thereby relieving muscle tension caused by prolonged sitting and stimulating abdominal movement.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A chair with a movable seat surface includes a support frame 1, a seat surface 2, and a backrest 3. The support frame 1 has at least two parallel longitudinal slide rails 5, and each longitudinal slide rail 5 has at least two longitudinal sliders 7 running through it. A transverse slide rail 4 is connected to the longitudinal slide rails 5 via the longitudinal sliders 7. At least one transverse slide rail 4 is provided, and a transverse slider 6 is provided on the transverse slide rail 4. The seat surface 2 is mounted on the transverse slider 6 and can move along any trajectory in any direction on the horizontal plane as the longitudinal sliders 7 and transverse sliders 6 move. The backrest 3 is fixedly mounted on the support frame 1. For users who sit for long periods, the chair allows for trunk movement in sitting or reclining positions, relieving muscle tension caused by prolonged sitting and stimulating abdominal activity.

[0007] Preferably, the longitudinal slide rail 5 is provided with two rails, namely a first longitudinal slide rail 501 and a second longitudinal slide rail 502, which are arranged in parallel and have equal lengths.

[0008] Preferably, the transverse slide rail 4 is provided with two rails, namely a first transverse slide rail 401 and a second transverse slide rail 402, which are arranged in parallel and have equal lengths.

[0009] Preferably, the longitudinal slider 7 includes a first longitudinal slider 701, a second longitudinal slider 702, a third longitudinal slider 703, and a fourth longitudinal slider 704. The second longitudinal slider 702 and the third longitudinal slider 703 are disposed through the first longitudinal slide rail 501, and the first longitudinal slider 701 and the fourth longitudinal slider 704 are disposed through the second longitudinal slide rail 502. The two ends of the first transverse slide rail 401 are respectively connected to the first longitudinal slider 701 and the second longitudinal slider 702, and the two ends of the second transverse slide rail 402 are respectively connected to the third longitudinal slider 703 and the fourth longitudinal slider 704. The reciprocating motion of the longitudinal slider 7 on the longitudinal slide rail 5 can drive the seat and the user to move back and forth.

[0010] Preferably, there are at least two horizontal sliders 6, and each horizontal slider 6 is the same size.

[0011] Preferably, there are two horizontal sliders 6, namely a first horizontal slider 601 and a second horizontal slider 602. The reciprocating motion of the horizontal sliders 6 on the horizontal slide rail 4 can drive the seat surface and the user to move left and right. At the same time, when the horizontal sliders 6 are fixed, the left and right movement of the horizontal slide rail 4 between the two vertical sliders 7 can also drive the seat surface and the user to move left and right.

[0012] Preferably, the seat 2 and backrest 3 are designed to meet ergonomic requirements, the tilt of the backrest 3 is adjustable, and the seat 2 is covered with a soft pad to facilitate users to change their sitting posture when sitting for a long time.

[0013] Preferably, the support frame 1 has four support legs on the side closest to the ground to maintain the stability of the support frame.

[0014] Compared with existing technologies, the present invention has the following advantages: The technical solution provided by the present invention enables the user to swing their torso in a sitting or supine position, thereby relieving muscle tension caused by prolonged sitting and stimulating abdominal activity. The present invention also has the advantages of simple structure and ease of manufacture. Attached Figure Description

[0019] The following detailed embodiments further illustrate the above-described content of the present invention. However, this should not be construed as limiting the scope of the present invention to the following examples. All technologies implemented based on the above-described content of the present invention fall within the scope of the present invention.

[0020] In the following embodiments, the settings of directions such as front and back, left and right, up and down are only for the purpose of illustrating the relative relationships and do not limit the scope of protection and use.

[0021] In view of the shortcomings of the existing technology, the present invention will provide a new technical solution, which provides a seat with a movable seat surface, which can realize the swinging of the torso in a sitting or reclining position, thereby relieving muscle tension caused by prolonged sitting and promoting abdominal movement.

[0022] like Figures 1-2As shown, a chair with a movable seat surface includes a support frame 1, a seat surface 2, and a backrest 3. The support frame 1 has at least two parallel longitudinal slide rails 5, and each longitudinal slide rail 5 has at least two longitudinal sliders 7 running through it. A transverse slide rail 4 is connected to the longitudinal slide rails 5 via the longitudinal sliders 7. There are at least two transverse slide rails 4, each with a transverse slider 6. The seat surface 2 is placed on the transverse sliders 6 and moves along any trajectory in any direction on the horizontal plane as the longitudinal sliders 7 and transverse sliders 6 move. The backrest 3 is fixedly mounted on the support frame 1. For users who sit for long periods, the chair allows for trunk movement in sitting or reclining positions, relieving muscle tension caused by prolonged sitting and promoting abdominal movement. The two longitudinal slide rails 5 are a first longitudinal slide rail 501 and a second longitudinal slide rail 502, arranged parallel to each other and of equal length. The two transverse slide rails 4 are a first transverse slide rail 401 and a second transverse slide rail 402, arranged parallel to each other and of equal length. The longitudinal slider 7 includes a first longitudinal slider 701, a second longitudinal slider 702, a third longitudinal slider 703, and a fourth longitudinal slider 704. The second longitudinal slider 702 and the third longitudinal slider 703 are connected through the first longitudinal slide rail 501, and the first longitudinal slider 701 and the fourth longitudinal slider 704 are connected through the second longitudinal slide rail 502. The first transverse slide rail 401 is connected at both ends to the first longitudinal slider 701 and the second longitudinal slider 702, respectively. The second transverse slide rail 402 is connected at both ends to the third longitudinal slider 703 and the fourth longitudinal slider 704, respectively. The reciprocating motion of the longitudinal slider 7 on the longitudinal slide rail 501 can drive the seat and the user to move back and forth. At least two transverse sliders 6 are provided, each of the same size. There are two transverse sliders 6: a first transverse slider 601 and a second transverse slider 602. The reciprocating motion of the transverse sliders 6 on the transverse slide rail 4 can drive the seat and the user to move left and right. Simultaneously, when the horizontal slider 6 is fixed, the left-right movement of the horizontal slide rail 4 between the two vertical sliders 7 can also drive the seat surface and the user to move left and right. The seat surface 2 and backrest 3 are designed to meet ergonomic requirements. The tilt of the backrest 3 is adjustable, and the seat surface 2 is covered with a soft cushion to facilitate users changing their sitting posture when sitting for a long time. The support frame 1 has four support legs on the side closest to the ground to maintain the stability of the support frame.

[0023] Obviously, based on the above description of the present invention, and according to common technical knowledge and conventional methods in the field, various other modifications, substitutions or alterations can be made without departing from the basic technical concept of the present invention.
