Description

Technical Field

[0001] The invention belongs to the technical field of seat cushions, and in particular relates to a detachable sitting posture correction seat cushion and a manufacturing process thereof. Background Art

[0002] The common sitting posture correction cushions on the market nowadays mostly use an overall correction structure, or simply distinguish between the buttocks, legs, and waist. For users of different body types, because there is no targeted division and correction of the specific pelvic bone structure, the support and correction effects of the entire pelvis and lumbar spine often cannot meet expectations. The reason is that multi-modular cushions have certain problems in terms of versatility. For users of different body types, it is impossible to find a fixed and unified structure to meet their needs, and a certain degree of adjustment is required. In addition, as people pay more and more attention to health issues, for people who sit for a long time, relieving back pain through massage has become a solution trend. Summary of the invention

DETAILED DESCRIPTION

[0027] As shown in the figure, a detachable sitting posture correction cushion includes a backboard 108, a foam pad, a connecting component and a functional module. The backboard 108 is integrally formed by mold injection molding, and the manufactured backboard 108 includes a backrest 109 and a bearing portion 110. According to ergonomic research, the angle between the trunk and the thigh is 95 degrees, which is the most comfortable, so the angle between the backrest 109 and the bearing portion 110 is preferably 95 degrees. Considering the differences in the body shapes of users of different body shapes, the angle between the backrest 109 and the bearing portion 110 can be 90 to 100 degrees. The angle between the backrest 109 and the bearing portion 110 can be set to 90 degrees or 100 degrees to meet the needs of users of different body shapes.

[0028] The two sides of the front end of the backrest 109 are bent forward, and the two sides of the upper end of the bearing part 110 are bent upward, so as to form a wrapping support structure. The front end of the backrest 109 and the upper end of the bearing part 110 of the back plate 108 are divided into the fifth lumbar vertebra and transverse process, ilium, sacrum, coccyx, hip joint, ischium, femur and pubic area according to the position of the human skeleton. According to the shapes of the corresponding positions of the fifth lumbar vertebra and transverse process, ilium, sacrum, coccyx, hip joint, ischium, femur and pubic on the back plate 108, the fifth lumbar vertebra and transverse process pad 101, ilium pad 102, sacrum pad 103, coccyx pad 104, hip joint pad 105, ischium pad 106, femur pad 107 and pubic pad 111 are made by foaming process. The ilium pad 102, sacrum pad 103, coccyx pad 104, hip joint pad 105, femur pad 107 and ischium pad 106 are provided with a mounting groove in the middle of one end away from the back plate 108, and the mounting groove is made during foaming to facilitate the installation of functional modules. The end surfaces of the ilium pad 102, sacrum pad 103, coccyx pad 104, hip joint pad 105, ischium pad 106, femur pad 107 and pubic pad 111 are concavely processed on one side to make their edges flat and the middle part concave to form a wrapping structure, thereby reducing body pressure and improving comfort. According to users of different body shapes, the fifth lumbar vertebra and transverse process pad 101, ilium pad 102, sacrum pad 103, coccyx pad 104, hip joint pad 105, ischium pad 106, femur pad 107 and pubic pad 111 of different thicknesses can be made. In order to prevent spinal diseases and keep the human body in the most natural state, when sitting, the pelvis should be in an upright state and the spine should present a natural S-shaped posture, so the thickness of the fifth lumbar vertebra and the transverse process pad 101 is greater than the thickness of the sacrum pad 103 and the coccyx pad 104, thereby forming a lumbar support.

[0029] The installation positions of each foam pad on the back plate 108 are as follows:

[0030] The fifth lumbar vertebra and transverse process pad 101, the sacrum pad 103, and the coccyx pad 104 are detachably installed in the middle part of the front end of the backrest 109 from top to bottom through the connecting components, and a pair of ilium pads 102 are symmetrically and detachably installed on the upper half of both sides of the front end of the backrest 109 through the connecting components; a pair of hip joint pads 105 are symmetrically and detachably installed on the lower half of both sides of the front end of the backrest 109 through the connecting components; the ischium pad 106 and the pubic pad 111 are detachably installed in the middle part of the upper end surface of the bearing part 110 from back to front through the connecting components, and a pair of femoral pads 107 are symmetrically and detachably installed on both sides of the upper end surface of the bearing part 110 through the connecting components.

[0031] In order to relieve riding fatigue and improve riding comfort, functional modules are detachably installed in the mounting grooves provided on the ilium pad 102, the sacrum pad 103, the coccyx pad 104, the hip joint pad 105, the femur pad 107 and the ischium pad 106. The functional modules can be selected from massage modules or heating modules.

[0032] The heating module includes an electric heating wire, which is evenly bonded to the installation grooves provided in the ilium pad 102, the sacrum pad 103, the coccyx pad 104, the hip joint pad 105, the femur pad 107 and the ischium pad 106 by high temperature resistant glue. The electric heating wire is then connected to the wire, which passes through the through hole provided on the back plate 108 and extends to the rear end of the backrest 109 of the back plate 108 or the lower end of the bearing part 110. The wire is then connected to the controller, and the controller is set so that the maximum temperature heated by the electric heating wire is 40 degrees Celsius. The controller is fixedly installed at the rear end of the backrest 109 by bolts. The electric heating wire can be controlled by the controller to heat the seat cushion.

[0033] The massage module includes an elastic pad 201, a pipeline 202, a push cylinder and a push connecting rod. The elastic pad 201 is installed on the push connecting rod, and the elastic pad 201 is an internal hollow structure. The elastic pad 201 is connected to the push mechanism and installed in the installation grooves provided in the ilium pad 102, the sacrum pad 103, the coccyx pad 104, the hip joint pad 105, the femur pad 107 and the ischium pad 106. The pipeline 202 is installed in the gap between the foam pads, and the pipeline 202 is connected to the controller 203. The controller 203 can control the push cylinder to drive the push connecting rod to perform massage.

[0034] The connection component can be a mushroom head Velcro or a nano-absorption gel sheet, or a bolt connection or a sliding slot connection. The mushroom head Velcro has a high adhesive strength and can be used for multiple cycles. When the bolt connection is selected, one end of the hollow metal expansion bolt is fixedly bonded to the fifth lumbar vertebra and transverse process pad 101, pubic pad 111 wrapped in fabric, and the iliac pad 102, sacral pad 103, coccygeal pad 104, hip joint pad 105, ischium pad 106, and femoral pad 107 installed with a massage module or a heating module, and the other end of the hollow metal expansion bolt is installed on the back plate 108. When the card slot connection is selected, card blocks are glued on the fifth lumbar vertebra and transverse process pad 101, pubic pad 111 wrapped by fabric, and iliac pad 102, sacrum pad 103, coccyx pad 104, hip joint pad 105, ischium pad 106, and femoral pad 107 equipped with massage modules or heating modules, and then a card slot is processed on the back plate 108 so that the card block can be embedded in the card slot.
