[0002] A lumbar pillow is a cushion that can be placed on a chair, sofa, or bed, primarily to provide lumbar support and comfort. Its design helps maintain a normal lumbar spine posture, relaxing the lumbar muscles whether sitting or lying down. This can alleviate excessive stretching of the lumbar muscles caused by improper posture for those who sit or lie for extended periods, thereby reducing lumbar fatigue and discomfort. Existing lumbar pillows typically use a memory-rich pure cotton design, which provides a relatively snug and comfortable support. However, these pillows struggle to provide adequate support for the user's waist and back, and the support position cannot be adjusted, making long-term use difficult to relieve fatigue.

[0003] According to application number CN201410479185.9, a car seat assembly and a car lumbar pillow are provided, which include a lumbar pillow body and two elastic straps for restraining the lumbar pillow body to the seat. The two elastic straps are respectively arranged on the left and right sides of the lumbar pillow body, and the free ends of the two elastic straps cooperate with each other. The lumbar pillow body includes an outer lumbar protection part and an inner support part. The center of the lumbar protection part is hollowed out, and the support part is arranged at the center of the lumbar protection part. The shape and size of the support part match the central hollow part of the lumbar protection part. The support part and the lumbar protection part are hinged through an angle adjuster.

[0004] The above document adjusts the position and angle of the lumbar pillow through elastic straps and angle adjusters to adapt to different passengers to meet different usage needs, but it cannot adjust the appropriate support position according to the user's back, and cannot achieve the effect of relieving fatigue.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Example

[0025] Please refer to the attached Figure 1 、 2 As shown, a multi-directional three-dimensional lumbar support pillow includes a cotton cover 10, a first annular frame 11 arranged inside the cotton cover 10, a second annular frame 12 arranged on one side of the first annular frame 11, two back support rods 13 arranged in the middle of the first annular frame 11, a first adjustment component 14 arranged at the top of the two back support rods 13, a second adjustment component 15 arranged at the bottom of the two back support rods 13, and a waist adjustment component 16 arranged at the bottom of the first annular frame 11; the cotton cover 10 includes a cushion 101, two lumbar pads 102 arranged at both ends of the lower half of one side of the cushion 101, two nylon belts 103 arranged in the middle of both ends of the cushion 101, and Velcro 104 arranged on the side of the other end of the nylon belt 103.

[0026] It should be noted that the second annular frame 12 is fixedly connected to the first annular frame 11 by several metal rods. The nylon strap 103 has a certain degree of elasticity, which can prevent the Velcro 104 from breaking due to deformation when the user leans on the cushion 101. The entire cotton cover 10 is made of hollow but sufficiently thick memory foam to prevent the internal structure from getting stuck and also prevent discomfort caused by the internal frame being too hard.

[0027] Furthermore, the device is placed on a seat according to the user's back position, and two nylon straps 103 are passed around the seat and connected via Velcro 104;

[0028] Furthermore, the height of the back cushion 101 is adjusted, and the bonding area of ​​the Velcro 104 is adjusted in due time, so that the device is stably suspended and fixed on the seat.

[0029] Please refer to the attached Figure 3 、 4 5, the first annular frame 11 includes a first bidirectional threaded rod 111 rotatably arranged at the top, a first turbine 112 arranged in the middle of the first bidirectional threaded rod 111, a second bidirectional threaded rod 113 arranged at the bottom of the first annular frame 11, and a second turbine 114 arranged in the middle of the second bidirectional threaded rod 113; the back support rod 13 includes a first threaded sleeve 131 sleeved on the first bidirectional threaded rod 111, a second threaded sleeve 132 sleeved on the second bidirectional threaded rod 113, an L rod 133 arranged on the same side of the first threaded sleeve 131 and the second threaded sleeve 132, and a spring connecting the two L rods 133 of the same group. Spring 134; the first adjusting component 14 includes two supporting plates 141 provided at the upper and lower ends of the second annular frame 12, a first rotating rod 142 rotatably installed in the middle of the two supporting plates 141, a first worm 143 sleeved on the upper part of the first rotating rod 142 and engaged with the first turbine 112, and a first knob 144 provided at the top of the first rotating rod 142; the second adjusting component 15 includes a second rotating rod 151 rotatably installed in the middle of the two supporting plates 141, a second worm 152 sleeved on the lower end of the second rotating rod 151 and engaged with the second turbine 114, and a second knob 153 provided at the top of the second rotating rod 151.

[0030] It should be noted that the L-rod 133 is rotatably mounted on the side walls of the first threaded sleeve 131 and the second threaded sleeve 132. The function of the spring 134 is to adapt to the length change of the entire back support rod 13 when the L-rod 133 is offset and to prevent the two L-rods 133 in the same group from being misaligned. The first rotating rod 142 and the second rotating rod 151 are arranged on the left and right sides of the two support plates 141. The first turbine 112 and the second turbine 114 are also offset by corresponding distances on the first bidirectional threaded rod 111 and the second bidirectional threaded rod 113 respectively; the first knob 144 and the second knob 153 extend outside the cushion 101 to facilitate adjustment.

[0031] Furthermore, according to the back shape of the user, the first knob 144 is rotated, and the first worm 143 that rotates synchronously with the first rotating rod 142 is engaged to drive the first turbine 112 to rotate, thereby driving the first bidirectional threaded rod 111 to rotate;

[0032] Furthermore, the rotating first bidirectional threaded rod 111 drives the two first threaded sleeves 131 to move closer to or away from each other through engagement;

[0033] Furthermore, the second knob 153 is rotated, and the second worm gear 152 that rotates synchronously with the second rotating rod 151 is engaged to drive the second turbine 114 to rotate, thereby driving the second bidirectional threaded rod 113 to rotate;

[0034] Furthermore, the rotating second bidirectional threaded rod 113 drives the two second threaded sleeves 132 to move closer to or away from each other through engagement;

[0035] Furthermore, when the positions of the first threaded sleeves 131 and the second threaded sleeves 132 are adjusted, the two L-rods 133 of the same group installed on one side thereof are rotated to deflect the angle under the expansion and contraction of the springs 134 to adjust the support angle and support position of the two back support rods 13.

[0036] Please refer to the attached Figure 4 As shown, the waist adjusting component 16 includes two ratchet discs 161 provided at the bottom of the second threaded sleeve 132 and a third annular frame 162 provided at a side of the ratchet discs 161 away from the second annular frame 12 .

[0037] It should be noted that the ratchet disc 161 is installed at the bottom of the second threaded sleeve 132 because when the user adjusts the second threaded sleeve 132 to a suitable position, the ratchet disc 161 can be located exactly on both sides of the user's waist. There is enough hollow space inside the two waist pads 102 to accommodate the position adjustment of the third annular frame 162.

[0038] Furthermore, when the second threaded sleeve 132 is adjusted in position, the two ratchet discs 161 are also driven to move closer to and farther from each other, thereby adjusting the supporting positions of the two third annular frames 162 .

[0039] Furthermore, the waist pad 102 is moved so that the third annular frame 162 is subjected to force, thereby driving the ratchet disc 161 to rotate, and the waist pad 102 is adjusted to a position and angle suitable for the user's waist.

[0040] The working principle of this utility model is:

[0041] First, according to the position of the user's back, place the device on the seat, pass the two nylon belts 103 around the seat, connect them through the Velcro 104, adjust the height of the cushion 101, and adjust the bonding area of ​​the Velcro 104 in time to stably fix the device on the seat; according to the shape of the user's back, rotate the first knob 144, and the first turbine 112 is driven to rotate by the first worm 143 that rotates synchronously with the first rotating rod 142, and then the first bidirectional threaded rod 111 is driven to rotate. The rotating first bidirectional threaded rod 111 drives the two first threaded sleeves 131 to approach or move away from each other through engagement, and the second knob 153 is rotated, and the second turbine 114 is driven to rotate by the second worm 152 that rotates synchronously with the second rotating rod 151. The second bidirectional threaded rod 113 rotates, thereby driving the second bidirectional threaded rod 113 to rotate. The rotating second bidirectional threaded rod 113 drives the two second threaded sleeves 132 to approach or move away from each other through engagement. When the positions of the first threaded sleeves 131 and the second threaded sleeves 132 are adjusted, the two L rods 133 of the same group installed on one side thereof are rotated to deviate at an angle under the extension and contraction of the spring 134, thereby adjusting the support angle and support position of the two back support rods 13; when the second threaded sleeve 132 adjusts its position, the two ratchet discs 161 are also driven to approach or move away, adjusting the support position of the two third annular frames 162, and bending the lumbar pad 102, so that the third annular frame 162 is subjected to force and thereby drives the ratchet disc 161 to rotate, thereby adjusting the lumbar pad 102 to a position and angle suitable for the user's waist.

[0042] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
