Technical Field

[0001] This utility model relates to the field of integrated seat cushion technology, specifically an integrated seat cushion with an adjustable fixing strap. Background Technology

[0002] An integrated seat and backrest cushion is a design that combines the functions of a seat cushion and a backrest cushion. It is typically used to provide extra comfort and support and is suitable for chairs, sofas, car seats, and other similar applications. Integrated seat and backrest cushions are an ideal choice for improving sitting comfort and support, especially for users who sit for long periods of time while working or driving. Choosing the right materials and design can effectively reduce fatigue and discomfort, improving overall quality of life.

[0003] Hemiplegic patients often need to use wheelchairs to move between indoor and outdoor areas when going outdoors for fresh air or sunbathing. This wheelchair use is often prolonged and uncomfortable. While integrated seat cushions can alleviate the pressure of prolonged sitting, some hemiplegic patients are unable to sit stably in their wheelchairs or on the cushions due to their condition. Existing integrated seat cushions lack suitable fixation methods for hemiplegic patients or those requiring wheelchairs. Therefore, we propose an integrated seat cushion with adjustable and secure straps. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated seat cushion with an adjustable fixing strap, which solves the problem that hemiplegic patients are prone to slipping off the integrated seat cushion or are inconvenient to fix.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated seat cushion with an adjustable fixing strap includes an integrated seat cushion body, the surface of which is provided with ventilation holes and the side of which is provided with a slot.

[0007] It also includes a control unit, which can effectively fix different hemiplegic patients and prevent them from slipping when sitting or leaning.

[0008] The adjustment section is used to adjust the control section to fix the position of patients with different degrees of hemiplegia.

[0009] The control unit includes a buckle, which is fixedly connected to the surface of the integrated seat cushion body. A positioning block passes through the side of the integrated seat cushion body. A rotating column passes through and is rotatably connected to the inner side of the positioning block. A control box is fixedly connected to the top surface of the rotating column. A shaft passes through and is rotatably connected to the inner side of the control box. A strap is fixedly connected to the surface of the shaft. The strap passes through the control box. A clip is fixedly connected to one end of the strap located outside the control box.

[0010] Preferably, a fixing column is fixedly connected to the inner side of the control box, and the shaft passes through the fixing column and is rotatably connected.

[0011] Preferably, a ratchet is fixedly connected to one end of the shaft located inside the fixed post, and a spiral spring is fixedly connected between the surface of the shaft and the inner side of the fixed post.

[0012] Preferably, a push rod is slidably connected through the surface of the control box, and a pressure rod is fixedly connected to one end of the push rod located on the outside of the control box.

[0013] Preferably, a pawl is fixedly connected to the end of the push rod away from the pressure rod, and a return spring is fixedly connected between the pawl and the inner wall of the control box. The pawl passes through the fixed column and is slidably connected.

[0014] Preferably, the adjusting part includes a turntable, which is fixedly connected to the surface of the rotating column, and a fixing plate is fixedly connected to the inner side of the positioning block.

[0015] Preferably, the surface of the turntable is provided with an arc-shaped groove, the surface of the fixed plate is provided with a sliding groove, a sliding rod passes through the inner side of the sliding groove, the sliding rod passes through the arc-shaped groove, and an L-shaped locking block is passed through and fixedly connected to the end of the sliding rod away from the arc-shaped groove.

[0016] By employing the above technical solution, this utility model provides an integrated seat cushion with an adjustable fixing strap. It possesses at least the following beneficial effects:

[0017] (1) This utility model limits the ratchet by the pawl, so that the strap can only be pulled out and will not automatically return to its original position. After the buckle is inserted into the buckle, the pressure bar is pulled up, so that the pressure bar drives the pawl to rise through the push rod. Then the pawl no longer limits the ratchet, so that the spiral spring drives the shaft to reverse and tighten the strap, thereby fixing the hemiplegic patient and preventing the hemiplegic patient from sliding. At the same time, by pulling out and limiting the strap in one direction, and then locking it, the strap can be tightened and adjusted for hemiplegic patients of different body types, so as to avoid the strap being too long or too short, which would prevent some hemiplegic patients from being unable to use it.

[0018] (2) This utility model rotates the control box, which drives the rotating column to rotate. When the rotating column rotates, it drives the turntable located inside the positioning block to rotate as well. This causes the sliding rod in the arc groove on the surface of the turntable to slide in the arc groove. The sliding rod then causes the L-shaped locking block to retract, so that the L-shaped locking block will not get stuck in the hole inside the slot. This allows the positioning block to be moved and the height of the locking head to be adjusted to suit different hemiplegic patients. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] An integrated seat cushion with adjustable and securing straps, such as Figures 1-5As shown, the device includes an integrated seat cushion body 1, with ventilation holes 4 on its surface and a slot 5 on its side. The slot 5 has an inner hole for inserting an L-shaped locking block 36. It also includes a control unit 2 for effectively securing different hemiplegic patients and preventing them from slipping while sitting. An adjustment unit 3 is used to adjust the control unit 2 to fix the position of patients with different degrees of hemiplegia. The control unit 2 includes a buckle 21, which is fixedly connected to the surface of the integrated seat cushion body 1. A positioning block 22 penetrates the side of the integrated seat cushion body 1. A rotating column 23 is rotatably connected through the inner side of the positioning block 22. A control box 24 is fixedly connected to the top surface of the rotating column 23. A shaft 25 is rotatably connected through the inner side of the control box 24. A strap 29 is fixedly connected to the surface of the shaft 25. When a gripping head 210 is pulled, it pulls the strap 29 wound on the shaft 25, causing the strap 29 to rotate when pulled by the gripping head 210. Simultaneously, the strap 29 drives the shaft 25 to rotate as well. The strap 29 passes through the control box 24, and the end of the strap 29 located on the outside of the control box 24 is fixedly connected to the gripping head 210. A fixing column 26 is fixedly connected to the inner side of the control box 24, and the shaft 25 passes through and is rotatably connected to the fixing column 26. A ratchet 28 is fixedly connected to one end of the shaft 25 located inside the fixed post 26. When the shaft 25 rotates, it will drive the ratchet 28 to rotate as well. When the ratchet 28 rotates, the teeth of the ratchet 28 will abut against the pawl 212, causing the pawl 212 to retract upward and lock the ratchet 28 by the push of the return spring 214. This limits the shaft 25 by the ratchet 28. When the shaft 25 is pulled by the strap 29, it can rewind the spiral spring 27. However, under the limitation of the ratchet 28 by the pawl 212, the shaft 25 will not be driven to reverse by the rewinding spiral spring 27, thus ensuring the stability of the strap 29 being pulled out. The spiral spring 27 is fixedly connected between the surface of the shaft 25 and the inside of the fixed post 26. A push rod 211 is slidably connected through the surface of the control box 24. A pressure rod 213 is fixedly connected to one end of the push rod 211 located outside the control box 24. Pulling up the pressure rod 213 causes it to drive the pawl 212 to rise via the push rod 211. The pawl 212 then no longer limits the ratchet 28, causing the spiral spring 27 to reverse the shaft 25, thus tightening the strap 29 and securing the hemiplegic patient. A pawl 212 is fixedly connected to the end of the push rod 211 away from the pressure rod 213. A return spring 214 is fixedly connected between the pawl 212 and the inner wall of the control box 24. The pawl 212 passes through the fixing post 26 and is slidably connected.

[0029] In this embodiment, the locking head 210 is inserted into the buckle 21 along the leg of the hemiplegic patient to complete the fixation. The pawl 212 limits the ratchet 28, so that the strap 29 can only be pulled out and will not automatically return to its original position. After the locking head 210 is inserted into the buckle 21, the pressure rod 213 is pulled up, so that the pressure rod 213 drives the pawl 212 to rise through the push rod 211. Then the pawl 212 no longer limits the ratchet 28, so that the spiral spring 27 drives the shaft 25 to reverse and tighten the strap 29, thereby fixing the hemiplegic patient and preventing the hemiplegic patient from sliding. At the same time, through the one-way pull-out and limiting of the strap 29, and subsequent locking, the tightness can be adjusted for hemiplegic patients of different body types, so as to avoid the strap 29 being too long or too short, which would make it unusable for some hemiplegic patients.

[0030] Example 2

[0031] like Figures 4-5 As shown, the adjustment unit 3 includes a turntable 31, which is fixedly connected to the surface of the rotating column 23. A fixed plate 32 is fixedly connected to the inner side of the positioning block 22. An arc-shaped groove 33 is formed on the surface of the turntable 31, and a sliding groove 34 is formed on the surface of the fixed plate 32. A sliding rod 35 passes through the inner side of the sliding groove 34 and also passes through the arc-shaped groove 33. An L-shaped locking block 36 is fixedly connected to the end of the sliding rod 35 away from the arc-shaped groove 33. Rotating the control box 24 causes the rotating column 23 to rotate. When the rotating column 23 rotates, it will cause the turntable 31 located inside the positioning block 22 to rotate as well. This causes the sliding rod 35 to slide within the arc-shaped groove 33, and the sliding rod 35 will cause the L-shaped locking block 36 to retract, preventing the L-shaped locking block 36 from getting stuck in the hole inside the slot 5, thus allowing the positioning block 22 to be moved.

[0032] In this embodiment, rotating the control box 24 causes the rotating column 23 to rotate. When the rotating column 23 rotates, it causes the turntable 31 located inside the positioning block 22 to rotate as well. This causes the arc-shaped groove 33 on the surface of the turntable 31 to move the sliding rod 35 within the arc-shaped groove 33. The sliding rod 35 then causes the L-shaped locking block 36 to retract, preventing the L-shaped locking block 36 from getting stuck in the hole inside the slot 5. This allows the positioning block 22 to be moved, and the height of the locking head 210 to be adjusted to suit different hemiplegic patients.

[0033] In use, the integrated seat cushion with adjustable fixing strap of this utility model is first placed on the wheelchair of the hemiplegic patient. Then, the locking head 210 is grasped and pulled, causing the locking head 210 to pull the strap 29 wound on the shaft 25. The strap 29 rotates when pulled by the locking head 210, and at the same time, the strap 29 drives the shaft 25 to rotate as well. When the shaft 25 rotates, it drives the ratchet 28 to rotate as well. When the ratchet 28 rotates, the teeth of the ratchet 28 will abut against the pawl 212, causing the pawl 212 to retract upward and lock the ratchet 28 through the push of the return spring 214. This limits the shaft 25 through the ratchet 28. So when the shaft 25 is pulled by the strap 29, it can rewind the spiral spring 27. However, with the pawl 212 limiting the ratchet 28, the shaft 25 will not be wound by the spiral spring. The coil spring 27 reverses direction, ensuring the stability of the strap 29 when it is pulled out. Then, the locking head 210 is inserted into the buckle 21 along the leg of the hemiplegic patient to complete the fixation. The pawl 212 limits the ratchet 28, so that the strap 29 can only be pulled out and will not automatically return to its original position. After the locking head 210 is inserted into the buckle 21, the pressure rod 213 is pulled up, so that the pressure rod 213 drives the pawl 212 to rise through the push rod 211. Then the pawl 212 no longer limits the ratchet 28, so the coil spring 27 drives the shaft 25 to reverse direction and rewind and tighten the strap 29, thereby fixing the hemiplegic patient and preventing the hemiplegic patient from sliding. At the same time, through the one-way pull-out and limiting of the strap 29, and subsequent locking, the tightness can be adjusted for hemiplegic patients of different body types, so as to avoid the strap 29 being too long or too short, which would make it unusable for some hemiplegic patients.

[0034] Simultaneously, the control box 24 can be rotated, causing the control box 24 to drive the rotating column 23 to rotate. When the rotating column 23 rotates, it will drive the turntable 31 located inside the positioning block 22 to rotate as well. This causes the arc-shaped groove 33 on the surface of the turntable 31 to move the slide rod 35 to slide within the arc-shaped groove 33. The slide rod 35 will then cause the L-shaped locking block 36 to retract, preventing the L-shaped locking block 36 from getting stuck in the hole inside the slot 5. This allows the positioning block 22 to be moved, adjusting the height of the locking head 210 to suit different hemiplegic patients.
