Description

Technical Field

[0001] This invention relates to the field of home and office auxiliary products technology, specifically to a suspended pressure-relieving cushion and its method of use. Background Technology

[0002] Currently, with the accelerated pace of work and life, prolonged sitting has become a common phenomenon. Maintaining a sitting posture for a long time can easily lead to problems such as lower back pain and excessive pressure on the buttocks. As a result, various seat cushion products with pressure-relieving and support functions have emerged on the market. Common pressure-relieving seat cushions mainly include memory foam seat cushions, gel seat cushions, and inflatable seat cushions. These seat cushions disperse pressure on the buttocks through the elastic deformation of materials and air filling, which can alleviate the discomfort caused by prolonged sitting to a certain extent. However, these seat cushions have relatively simple structures and limited functions, and can usually only achieve basic support and cushioning effects.

[0003] Existing seat cushions still have the following shortcomings: most seat cushions have a fixed back support angle, which cannot be flexibly adjusted according to the user's body shape and sitting habits, resulting in poor lumbar fit and unsatisfactory support when used by different users; traditional seat cushions lack the synergistic effect of buttock suspension and pressure relief and back flexible support, making it difficult to fully distribute body pressure; seat cushions are generally bulky and do not have folding and storage functions, taking up a lot of space after use, making them inconvenient to carry around or put in a backpack, and failing to meet the needs of multiple usage scenarios such as office, home and travel.

[0004] Therefore, we have made improvements to this by proposing a suspension pressure-reducing seat cushion and its usage method. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the purpose of the present invention is to provide a suspension pressure-relieving cushion and its usage method.

[0008] Preferably, the airbag assembly includes an ergonomic airbag, which is fixedly connected to the central area inside the back pad. A connecting pipe is connected through one side of the ergonomic airbag, and the side of the connecting pipe away from the ergonomic airbag extends through the interior of the back pad to its outer side.

[0009] Preferably, the power assembly includes a connecting column, which is fixedly connected to the upper side wall of the back pad. A base plate is fixedly connected to the center of the side of the connecting column away from the suspension assembly. A motor is fixedly connected to the side of the base plate near the center area of ​​the back pad. The rotating end of the motor passes through one side of the connecting column to the other side. A crank is fixedly connected to the rotating end of the motor. A connecting rod is rotatably connected to the side of the crank away from the motor.

[0010] Preferably, a first groove is formed inside the center of the side of the connecting rod away from the motor, a second groove is formed at the upper part of the side of the connecting rod away from the motor, a circular groove is formed inside the end of the connecting rod away from the motor, a moving channel passes through the first groove and the second groove, an engaging channel passes through the circular groove and the second groove, and a fixing strip is fixedly connected to the side of the connecting rod near the first groove.

[0011] Preferably, the massage component includes an extension column, which is fixedly connected to the center of the side wall of the back pad. A vertical shaft is fixedly connected to the side of the extension column near the suspension component. The vertical shaft slides in a first groove. A connecting strip is slidably connected to the side wall of the second groove. A toothed rack is fixedly connected to the side of the connecting strip near the vertical shaft.

[0012] Preferably, a compression spring is fixedly connected to the side of the groove near the crank, and a slider is fixedly connected to the side of the compression spring away from the crank. The slider slides in the groove, and an extension block is fixedly connected to the upper end of the slider. The upper end of the extension block is fixedly connected to the lower end of the connecting strip after passing through a moving channel.

[0013] Preferably, the lower end of the rack is engaged with a gear, a connecting rod is fixedly connected to the side of the gear near the extension post, and the connecting rod is rotatably connected inside the fixing bar, and a massage head is fixedly connected to the side of the gear away from the connecting rod.

[0014] Preferably, the suspension component includes two sets of inflatable columns arranged in a rectangular array, which are fixedly connected to the upper and lower surfaces of the seat body. A connecting pipe II is connected to one side of several of the upper inflatable columns, and a main connecting pipe is connected to one end of several of the second connecting pipes. An inflation / deflation port is connected to the upper end of the main connecting pipe, and a ventilation pipe is connected between several of the upper inflatable columns and several of the lower inflatable columns.

[0015] A method for using a suspension pressure-relieving seat cushion includes the following steps: S1: Adjust your sitting posture, turn the handle to drive the worm gear to rotate the worm wheel, so that the back cushion rotates around the rotation axis. Adjust the back cushion tilt angle to a comfortable angle and then stop. S2: Inflate the suspension component through the inflation / deflation pipe. The upper and lower sets of inflation columns expand synchronously through the main connecting pipe, connecting pipe two and the ventilation pipe. Adjust the inflation pressure to the buttocks to obtain a feeling of suspension support. S3: Inflate the ergonomic airbag of the airbag assembly with gas, controlling the inflation volume via the connecting pipe. The airbag conforms to the curve of the human back, providing flexible support for the back. S4: Start the power unit, the motor drives the crank to drive the connecting rod to swing back and forth; S5: The linkage drives the massage component to move, the compressed spring works with the slider to drive the connecting bar and rack to move, and the gear transmission drives the massage head to rotate, performing targeted massage on both sides of the back; S6: After the preset massage duration, the power unit is turned off to maintain the inflatable support state and relieve pressure while sitting. S7: After use, release the gas inside the suspension component through the charging / discharging pipe, and at the same time empty the gas in the ergonomic airbag to complete the storage.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This device achieves multi-dimensional active pressure reduction and support of the seat cushion by setting up adjustment components, power components, massage components, and suspension components. Turning the handle drives the worm gear to rotate the worm wheel, allowing the back cushion to smoothly adjust its tilt angle around the rotation axis, ensuring that the lumbar support angle is adjustable for different users. At the same time, the motor drives the crank to drive the connecting rod to swing back and forth. Through the transmission of sliders, racks and pinions, the massage heads automatically perform fixed-point rotational kneading on both sides of the back, eliminating the need for manual massage. With the synchronous expansion of two sets of air columns arranged in a rectangular array, the buttocks receive uniform suspension support, effectively dispersing pressure on the buttocks, thereby comprehensively relieving fatigue in the lower back and buttocks caused by prolonged sitting and significantly improving sitting comfort.

[0017] 2. This device utilizes the independent inflation and deflation design of the ergonomic airbag and suspension component, as well as the fit structure between the airbag component and the back pad, to achieve independent adjustment and synergistic effect of flexible back support and hip suspension decompression. The inflation volume of the airbag and the inflation column is controlled by connecting pipe 1 and the inflation and deflation pipe port respectively, so that the back airbag adapts to the physiological curve of the human spine to avoid local pressure. At the same time, the suspension component forms an elastic support layer to reduce pressure points on the hips.

[0018] 3. After use, release the gas through the charging and discharging port at the same time, and turn the handle in the opposite direction to fold the back pad and the seat body together. No disassembly is required. After storage, it can be put into a backpack for carrying. This solves the problem of traditional pressure-relieving seat cushions being bulky and inconvenient to store, and takes into account the needs of multiple scenarios such as home, office and travel.
