Description

[Technical Field]

[0001] The present invention relates to chair cushions, and more particularly to molded adjustment structures in chair cushions. [Background technology]

[0002] Modern people generally lack exercise. They often sit, lie, or lean for long periods of time while working, using computers, playing video games, or watching television, forgetting to get up and move around regularly. While it's known that getting up and moving around regularly can improve blood circulation, burn calories, and promote health, many people fail to do so due to factors such as concentrating on work, playing games, or personal habits. This can lead to weight gain and sagging buttocks. Prolonged sitting, lying, or leaning can also lead to poor posture and lower back pain, among other ailments of modern society.

[0003] Therefore, there are several padded products or patented technologies that claim to provide support or shaping effects by adhering to specific parts of the human body. However, the design of these padded products or patented technologies focuses on whether the external shape is ergonomic. These padded products or patented technologies only fit specific parts of the human body, such as the buttocks, and when pressure is applied to specific parts of the human body, they are unable to support and are deformed. In reality, the structures of these padded products or patented technologies do not provide sufficient support and do not provide a satisfactory support and shaping effect.

[0004] Therefore, based on the above reasons, the present inventor has improved and innovated the above-mentioned prior art and filed patent applications such as Taiwan Patent No. I533825 "Support Molded Structure" and Taiwan Patent No. M486334 "Molded Support Structure." Although these patents can improve the shortcomings of the above-mentioned prior art, the molded support structure in the inventor's prior patent technology described above mainly corresponds to the buttocks and provides an adjustable molded support function in response to pressure when sitting, but does not correspond to leaning of the lower back, and does not provide a molded support function for the lower back. Therefore, when pressure is applied by the buttocks of the human body when sitting, it only has a molding function and a molding effect on the buttocks.

[0005] Also see Taiwan Patent No. I658821 "Posture Support Device" and Taiwan Patent No. M612796 "Cushion for Sitting Posture Correction Chair." Both of these patents are made of hard plastic plates, so the angle, size, shape, support, etc. of the seating and reclining areas cannot be adjusted. The angle, size, shape, and support of the seating and reclining areas are fixed, and cannot be appropriately adapted to different users.

[0006] Based on the above, the structure and function of conventional chair cushion technology are less than ideal and require improvement.

[0007] Therefore, the inventor has completed the present invention after countless practical tests and experiments based on his many years of practical experience in product design and development, and his active commitment to research and development. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Taiwan Patent No. I533825 Specification [Patent Document 2] Taiwan Patent No. M486334 Specification [Patent Document 3] Taiwan Patent No. I658821 Specification [Patent Document 4] Taiwan Patent No. M612796 Specification Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention aims to provide a shaped adjustment structure for a chair cushion that can extend the shaped support part up to the waist of the human body, and change the support angle between the buttocks plate and the waist plate in the shaped support part, thereby adjusting the size, shape, support force, etc. of the shaped support part and making it possible to appropriately accommodate different users, and that can enhance the shaped support effect of the chair cushion by having the waist plate and buttocks plate pull and link with each other. [Means for solving the problem]

[0010] To achieve the above-mentioned object, the present invention provides a shaped and adjustable structure for a chair cushion. The shaped and adjustable structure for a chair cushion comprises a chair cushion. The material of the chair cushion is selected from flexible materials. The chair cushion comprises a buttocks plate and a lumbar plate. The lumbar plate extends and bends to form a shaped support section together with the buttocks plate. Thus, the shaped support section extends to the lumbar region of the human body. The chair cushion has at least two cutouts to define at least two adjustment sections. One end of each adjustment section is connected to the buttocks plate, and the other end is located behind the lumbar plate. The other end of each adjustment section is connected to at least one adjustment unit, allowing relative movement and adjustment inward or outward. The buttocks plate and the lumbar plate are movable, and an adjustable support angle is defined between them.

[0011] Furthermore, the chair cushion is made of a material selected from ethylene vinyl acetate and polyethylene, and the surface of the chair cushion has a surface layer, the surface layer including a soft material, and the peripheral edge of the chair cushion is covered with an edge.

[0012] Furthermore, the cut portions are provided on both sides of the chair cushion, and when the chair cushion is unfolded into a flat surface, they extend upward and outward and are folded.

[0013] Furthermore, the buttocks plate is provided with at least two second cutouts to define at least two second adjustment parts, one end of each second adjustment part being connected to the buttocks plate and the other end of each second adjustment part being disposed on the rear side of the buttocks plate, and the other end of each second adjustment part being joined to at least one second adjustment unit, so that it can be relatively moved and adjusted inward or outward.

[0014] Furthermore, the second cuts may be provided on both sides of the buttocks plate and extend upward and outward when the buttocks plate is unfolded in a plane, or the second cuts may be provided on both sides of the buttocks plate and extend downward and outward when the buttocks plate is unfolded in a plane, and ....

[0015] Furthermore, the cut portion has a U-shape, so that the waist plate is divided into two third adjustment portions, and the two third adjustment portions are joined together by a third adjustment unit.

[0016] Furthermore, the adjustment unit is any one of a belt, a plastic buckle, a hook-and-loop fastener, a ratchet buckle, a string fastener, a magnetic suction device, and a snap, which can adjust the length.

[0017] Furthermore, the second adjustment unit is any one of a belt, a plastic buckle, a hook-and-loop fastener, a ratchet buckle, a string fastener, a magnetic suction device, and a snap, which can adjust the length. [Effects of the Invention]

[0018] By adopting the above-mentioned technical means, the shaped support portion can be expanded to support the buttocks of a person when sitting and the lower back when leaning back. The support angle between the buttock plate and the lower back plate can be changed by adjusting the adjustment portion. Furthermore, the size, shape, and support force of the shaped support portion can be adjusted to suit different users. The adjustment portion also allows the lower back plate and the buttock plate to be pulled and linked to each other. For example, when the buttocks of a person presses the buttock plate when sitting, tension is generated, causing the lower back plate to tilt further forward and support the lower back, thereby increasing the support force for the lower back. Furthermore, when the lower back of a person leans back and applies pressure to the lumbar plate, both sides of the buttock plate are pulled up, increasing the support force for the buttocks, thereby improving the shaped support effect of the chair cushion.

[0022] The hip plate 10 extends and is bent, so that the hip plate 10 and the lower back plate 20 form a shaped support portion A together.

[0023] The chair cushion 1 is provided with two cutouts 30, which divide the chair cushion 1 into two adjustment sections 31, one end of each adjustment section 31 being connected to the buttocks plate 10 and the other end of each adjustment section 31 being located behind the lumbar plate 20. The other end of each adjustment section 31 is joined to at least one adjustment unit 40, which allows the adjustment section 31 to be relatively movable inward or outward.

[0024] In one embodiment, the hip plate 10 and the lumbar plate 20 are movable to define an adjustable support angle therebetween, the support angle being between 70 degrees and 120 degrees.

[0025] This allows the present invention to provide an adjustable chair cushion and chair configuration.

[0026] In an embodiment, the chair cushion 1 is selected from the following materials: Ethylene Vinyl Acetate or Polyethylene.

[0027] In the embodiment, each of the cut portions 30 is provided on both sides of the chair cushion 1, and when the chair cushion 1 is unfolded in a flat state, it extends upward and outward and has a folded shape.

[0028] As a result, the other end of each adjustment portion 31 can be easily positioned behind the lumbar plate 20 and is movable and adjustable, so that the lumbar plate 20 and the buttocks plate 10 pull each other and move in tandem.

[0029] In an embodiment, the surface of the chair cushion 1 comprises a surface layer, which comprises a soft material such as foam.

[0030] This increases the comfort of the chair cushion 1 when the buttocks of the human body press against the chair and the lower back leans against it, and also improves the aesthetic appearance of the chair cushion 1.

[0031] In the embodiment, the peripheral edge of the chair cushion 1 is covered with an edge 50 .

[0032] This provides a protective effect to the peripheral edge of the chair cushion 1, and improves the aesthetic appearance of the chair cushion 1.

[0033] In an embodiment, the hip plate 10 has two recesses 11, so that the hip plate 10 can be extended and the feet of the human body can rest on it.

[0034] This makes the chair cushion 1 more ergonomic and provides better support and comfort for the legs of the human body.

[0035] In the embodiment, both sides of the buttocks plate 10 are gradually flared outwards and inclined.

[0036] This makes the chair cushion 1 more ergonomic and provides better contouring support and comfort to the sides of the buttocks and legs of the human body.

[0037] In this embodiment, the adjustment unit 40 is a belt whose length can be adjusted.

[0038] This allows the two adjustment portions 31 to be relatively movable inward or outward and adjustable.

[0039] The above is an introduction to the components of the present invention and the method of constructing them. Next, the characteristics and effects of the present invention in use will be introduced below.
