Description

Technical Field

[0001] This utility model belongs to the technical field of posture correction cushion structure, specifically referring to a posture correction cushion with deformation function. Background Technology

[0002] Currently, for people who sit for long periods at work or school, especially those who spend long hours hunched over computers, the forward-leaning posture, without lumbar support, causes the lumbar spine to change from a forward curve to a backward curve, increasing the burden on the lower back, causing tension in the lumbar muscles, and leading to lumbar strain. Therefore, posture-correcting cushions have emerged on the market to provide support for users.

[0003] For example, Chinese patent CN202230550203.3 describes a posture-correcting seat cushion, a mainstream one-piece posture-correcting seat cushion on the market. It features an ergonomic curve to provide lumbar support. Another example is Chinese patent CN201921353383.5, a portable lumbar support and posture-correcting seat cushion. This product, while providing support, also features easy folding for portability. Current posture-correcting seat cushions on the market only provide lumbar support through the limited deformation space of the plastic cushion itself. Users can hardly feel the backrest's restorative force, so prolonged sitting can still be quite strenuous. Therefore, there is a need in the market for a posture-correcting seat cushion with a restorative backrest. Summary of the Invention

[0004] The purpose of this invention is to provide a posture-correcting seat cushion with deformation function.

[0005] The purpose of this utility model is achieved as follows:

[0006] A posture-correcting cushion with deformation function includes a cushion body and a backrest body. The cushion body and the backrest body are independent of each other and are connected by at least one elastic piece. One end of the elastic piece is fixed to the cushion body and the other end is fixed to the backrest body. When an external force is applied, the elastic piece can deform, thereby allowing the backrest body to move relative to the cushion body.

[0007] A gap greater than 1 cm is provided between the backrest body and the seat cushion body;

[0008] Both sides of the seat cushion and backrest are curved, with the curved sides of the seat cushion causing the user's buttocks to move towards the center; the curved sides of the backrest cause the user's back to move towards the center.

[0009] Furthermore, an elastic piece is provided in the middle of the seat cushion body and the backrest body. Due to the gap, the elastic piece is partially suspended, allowing the backrest body to move back and forth and twist left and right relative to the seat cushion body.

[0010] Furthermore, both the seat cushion body and the backrest body are provided with mounting grooves for limiting elastic pieces, with the elastic pieces resting against the mounting grooves.

[0011] Furthermore, it includes fasteners that secure the elastic sheet within the mounting groove; and the fasteners are located at the ends of the elastic sheet, with the portion of the elastic sheet that rests against the mounting groove but is not locked by the fasteners being able to disengage from the inside of the mounting groove.

[0012] Furthermore, a cover is fixed to the lower end of the seat cushion body, the cover covering or partially covering the mounting groove, the cover keeping the part of the seat cushion body in contact with the ground flat.

[0013] Furthermore, the upper end of the elastic sheet and the main body of the backrest are integrally formed; and / or, the lower end of the elastic sheet and the main body of the seat cushion are integrally formed.

[0014] Furthermore, the surface of the elastic sheet is provided with casting holes or casting steps.

[0015] Furthermore, the length of the elastic sheet that rests against the backrest body is at least 1 / 3 of the length of the backrest body; the length of the elastic sheet that rests against the seat cushion body is at least 1 / 3 of the length of the seat cushion body.

[0016] Furthermore, the elastic sheet is a metal component.

[0017] Furthermore, the backrest body is provided with a carrying handle.

[0018] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0019] 1. This utility model uses elastic sheets to support the seat cushion and backrest. The elastic sheets allow the posture-correcting seat cushion to elastically return to its original position, providing both effective support and a certain elastic return force, making the user more comfortable in various postures such as sitting back, stretching, etc. Furthermore, the elastic sheets can be configured in several ways: Method 1: A single elastic sheet is placed in the middle, allowing the backrest to move back and forth and twist left and right relative to the seat cushion, adding a small lateral twisting function and improving user comfort. Method 2: Two elastic sheets are placed on both sides, allowing the backrest to move back and forth relative to the seat cushion, providing better support than Method 1, but losing the lateral twisting function.

[0020] 2. The elastic sheet of this utility model can be fixed in the following two ways: Method 1: Both the seat cushion body and the backrest body are provided with mounting grooves for the limiting elastic sheet, and the elastic sheet is attached to the mounting groove. The elastic sheet is fixed in the mounting groove by fasteners. Preferably, the fasteners are located at the ends of the elastic sheet, and the part of the elastic sheet that is attached to the mounting groove but not locked by the fasteners can be detached from the inner side of the mounting groove. The structure allows for deformation space between the elastic sheet and the seat cushion body and the backrest body, making the connection point between the elastic sheet and the seat cushion body and the backrest body less susceptible to large shear forces, which helps to extend the life of the elastic sheet. Method 2: The elastic sheet and the seat cushion body are integrally molded and / or the elastic sheet and the backrest body are integrally molded. The integrally molded structure is more stable and has stronger overall continuity. In order to make the integrally molded elastic sheet more stable, the surface of the elastic sheet is provided with casting holes or casting steps. When the plastic part is integrally molded, it is tightly connected with the casting holes or casting steps. Under the action of external force, the elastic sheet is not easy to separate from the seat cushion body / backrest body.

[0021] 3. The lower end of the seat cushion body of this utility model is fixed with a cover. The purpose of the cover is: a) to cover or partially cover the mounting groove, so that the part of the seat cushion body in contact with the ground remains flat, making the posture corrective seat cushion more comfortable on the ground without any unevenness. b) to protect the mounting groove, and also to protect the connection position between the elastic sheet and the mounting groove.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-9 As shown:

[0035] A posture-correcting seat cushion with deformation function includes a seat body 1 and a backrest body 2. The seat body 1 and the backrest body 2 are independent of each other and are connected by at least one elastic piece 3. One end of the elastic piece 3 is fixed to the seat body 1 and the other end is fixed to the backrest body 2. When an external force is applied, the elastic piece can deform, thereby allowing the backrest body to move relative to the seat body. A gap greater than 1 cm is provided between the backrest body and the seat body. The gap between the backrest body and the seat body is L1, which provides deformation space. When the user leans back, the backrest body can move backward, and the gap can effectively avoid the user's coccyx, reducing the compression of the user's coccyx and making the user more comfortable to sit on. When the gap exceeds 1 cm, the gap will not trap the user's clothing. Both sides of the seat cushion body 1 and the backrest body 2 are raised to form arc-shaped parts. The attached diagram shows the arc-shaped part 19 of the seat cushion body and the arc-shaped part 29 of the backrest body. The arc-shaped part 19 of the seat cushion body allows the user's buttocks to lean towards the center; the arc-shaped part 29 of the backrest body allows the user's back to lean towards the center, improving the effect of posture correction.

[0036] like Figure 2 and Figure 3 As shown, the length of the elastic sheet attached to the backrest body is L2, and the length of the backrest body is L3, with L2 being at least 1 / 3 of the length of L3; the length of the elastic sheet attached to the seat cushion body is L4, and the length of the seat cushion body is L5, with L4 being at least 1 / 3 of the length of L5. By limiting the length of the elastic sheet, a tighter and more stable connection can be made between the elastic sheet and the backrest body and the seat cushion body.

[0037] The elastic sheet 3 is a metal component. Metal components have high strength and can maintain a specified shape for a long time; alternatively, fiber materials can also be used. The specific elasticity of the elastic sheet is selected by the manufacturer based on actual conditions. Different elasticity levels can be obtained by adjusting the rigidity, material, and thickness of the elastic metal sheet.

[0038] The backrest body 2 is provided with a handle hole 21.

[0039] A cover 4 is fixed to the lower end of the seat cushion body 2. The cover 4 covers or partially covers the seat cushion body mounting groove 12, and the cover keeps the part of the seat cushion body in contact with the ground flat. If the one-piece molding method described below is used, the cover is not required. If the fastener fixing method is used, the cover 4 must be provided.

[0040] Example 1: An elastic strip is provided in the middle of the seat cushion body and the backrest body. Due to the gap, the elastic strip is partially suspended, allowing the backrest body to move back and forth and twist left and right relative to the seat cushion body. The width of the elastic strip is controlled by the manufacturer, and both the width and strength of the elastic strip will change the range of deformation when the user leans back.

[0041] The upper end of the elastic sheet and the main backrest are integrally formed; and / or, the lower end of the elastic sheet and the main seat cushion are integrally formed. The elastic sheet can be integrally formed or fixed with fasteners. The fastener fixing scheme will be described in Example 2. Both integral forming and fastener fixing are acceptable, and manufacturers can choose according to their own circumstances.

[0042] The surface of the elastic sheet 3 is provided with a casting hole 31 or a casting step.

[0043] Example 2: Two elastic pieces 3 are provided in the middle of the seat cushion body 1 and the backrest body 2. Both the seat cushion body and the backrest body are provided with mounting grooves for the limiting elastic pieces. The two sides of the elastic pieces respectively abut against the seat cushion body mounting groove 12 and the backrest body mounting groove 22. Fasteners are included to fix the elastic pieces in the mounting grooves. The fasteners can be screws 27 and nuts 28, or rivets. Preferably, the fasteners are located at the ends of the elastic pieces, and the portion of the elastic piece abutting against the mounting groove but not locked by the fasteners can detach from the inner side of the mounting groove.

[0044] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
