Description

Technical Field

[0001] This utility model relates to the technical field of pillow bodies, and more specifically, to a lumbar support pillow. Background Technology

[0002] Lumbar support products are suitable for people who travel and sit for long periods, especially those who work long hours, travel for business, or go on vacation. People who work long hours are increasingly prone to lumbar muscle strain due to prolonged sitting, which can seriously affect work efficiency and quality of life. Furthermore, with the accelerated pace of life, the frequency of business trips and travel has increased significantly, and long-distance travel on public transportation (such as high-speed trains, airplanes, and cars) has become the norm. However, public transportation seats are often designed without effective lumbar support, which can easily lead to increased pressure on the lumbar spine and cause discomfort.

[0003] Currently, the main types of lumbar support products on the market include seat cushions, fixed lumbar supports, and inflatable lumbar supports. While these products can provide support for the user's lower back, they still have some drawbacks. First, existing lumbar support products are usually installed on the seats of vehicles. Specifically, users need to install the lumbar support product on the seat when getting on the vehicle and remove it when getting off. Furthermore, when users have multiple transfers during business trips, existing lumbar support products need to be repeatedly installed and removed, resulting in poor convenience. Second, in business trips and travel, existing lumbar support products are not very portable. Except for inflatable lumbar support products, they take up a lot of luggage space when stored.

[0026] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0027] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment herein. This phrase appearing in the specification does not necessarily refer to the same embodiment, nor is it limited to mutually exclusive, independent, or alternative embodiments. Those skilled in the art will understand that the embodiments herein can be combined with other embodiments without causing structural conflicts.

[0028] In this description, unless otherwise expressly specified and limited, the technical terms "installation," "connection," "joining," etc., should be interpreted broadly, and can refer to movable connections, fixed connections, or integration. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0029] In this description, terms such as “up,” “down,” “left,” “right,” “height,” “length,” and “width,” which indicate orientation or positional relationships, are intended to accurately describe the embodiments and simplify the description, rather than to limit the parts or structures involved to have a specific orientation or to be installed or operated in a specific orientation.

[0030] Please see Figure 1 and Figure 2 The figures shown are a first-view perspective view and a top view view of the pillow core of this application, respectively. The lumbar support pillow includes a pillow core 1, which is elongated. The pillow core 1 has a spinal pressure relief area 2 and two lumbar muscle support areas 3. The spinal pressure relief area 2 and the two lumbar muscle support areas 3 are located in the middle of the pillow core 1. The spinal pressure relief area 2 is located between the two lumbar muscle support areas 3, and the support height of the two lumbar muscle support areas 3 is greater than the support height of the spinal pressure relief area 2, so as to adapt to the posterior structure of the human waist. Through the cooperation of the spinal pressure relief area 2 and the two lumbar muscle support areas 3, the structure of the pillow core 1 can be made ergonomic and have a good lumbar muscle support and spinal pressure relief effect.

[0031] Furthermore, the pillow core 1 includes a main support portion 11 and two side surrounding portions 12. Specifically, when a user wears the lumbar support pillow, the main support portion 11 is used to fit the back of the waist, and the side surrounding portions 12 are used to fit the left and right sides of the waist. The spinal pressure relief area 2 and the lumbar muscle support area 3 are both located in the main support portion 11. The advantage of this design is that the spinal pressure relief area 2 can match the position of the spine, and the lumbar muscle support area 3 can fit the lumbar muscles. The two side surrounding portions 12 are located at both ends of the main support portion 11. The cross-section of the side surrounding portions 12 gradually decreases in the direction away from the main support portion 11. Specifically, as the cross-section of the side surrounding portions 12 decreases, the side contact area between the pillow core 1 and the left and right sides of the waist also decreases. The advantage of this design is that it can effectively reduce the degree of restriction on the left and right sides of the waist, facilitate heat dissipation on the left and right sides of the waist, and reduce the overall volume of the pillow core 1 so as to make it easy to roll up and store.

[0032] Preferably, in some embodiments, the cross-sections of both the main support portion 11 and the side surrounding portion 12 are elliptical.

[0033] Please see Figure 3 The image shows a top view of the pillow core of this application, and a cross-sectional view along the AA direction. The main support part 11 includes a lumbar contact surface 111 and a seat contact surface 112. Specifically, the lumbar contact surface 111 is an arc surface used to fit the human waist, and the seat contact surface 112 is an arc surface used to fit the back of the seat. The convex curvature of the seat contact surface 112 is smaller than that of the lumbar contact surface 111. The advantage of this solution is that, on the one hand, the convex curvature of the lumbar contact surface is larger, which can better support the back of the human waist; on the other hand, the convex curvature of the seat contact surface 112 is smaller, which can better fit the back of the seat, making the lumbar support pillow more comfortable to use. Preferably, the convex curvature of the seat contact surface 112 can be close to a plane or be a plane. Furthermore, the front and rear side structures of the side surround part 12 are the same as those of the main support part 11, which makes the long strip-shaped pillow core 1 have structural and visual continuity.

[0034] Please see Figure 4 The image shown is a second perspective perspective view of the pillow core of this application. The surface of the lumbar muscle support area 3 is provided with several raised ribs 31. The raised ribs 31 can provide a massage sensation to the waist to relieve muscle fatigue caused by prolonged sitting. The raised ribs 31 are arranged in a wave-like or "U" shape and are spaced apart. Multiple ventilation grooves are formed between the raised ribs 31, which makes it easier for air to circulate in the lumbar muscle support area 3, thereby improving breathability and reducing stuffiness.

[0035] Please see Figure 5The image shows a front view of the pillow core of this application. The rib 31 includes a raised side 311 and a flat side 312. Specifically, the raised side 311 is located on the side of the lumbar muscle support area 3 away from the spinal pressure relief area 2, while the flat side 312 is located on the side of the lumbar muscle support area 3 close to the spinal pressure relief area 2. The height of the raised rib 31 gradually decreases from the raised side 311 to the flat side 312. The advantage of this design is that it can avoid the rib 31 from producing a foreign body sensation near the spinal pressure relief area 2, making the support softer and more natural. It can also form a smooth pressure transition, reduce local pressure points, and improve fit.

[0036] Please see Figure 6 The figure shows a perspective view of the inner sleeve of this application. The pillow core 1 is fitted with an inner sleeve 5, which is located between the pillow core 1 and the pillow cover 10. The inner sleeve 5 is provided with at least one receiving cavity 51 for placing a heat patch. Specifically, after the user wears the lumbar support pillow, the user rotates the lumbar support pillow 180 degrees around the waist. At this time, the receiving cavity 51 for placing the heat patch fits against the user's abdomen, thereby achieving the effect of applying heat to the abdomen and providing abdominal heat therapy.

[0037] Preferably, in this embodiment, the accommodating cavity 51 is provided with an insertion end 511 for inserting a heat patch.

[0038] Preferably, in this embodiment, the inner sleeve 5 is provided with two accommodating cavities 51. The two accommodating cavities 51 work together to cover a spinal pressure relief area 2 and two lumbar muscle support areas 3, which has a larger heat treatment area and a better heat treatment effect.

[0039] Please see Figure 7 and Figure 8 The figures show the lumbar support pillow in its wearing state and its stored state, respectively. The lumbar support pillow includes a pillowcase 10, which is fitted onto the pillow core 1. The pillowcase 10 has connectors 4 at both ends. By cooperating with the two connectors 4, the lumbar support pillow can be worn on the waist of the user or fixed to a seat. The advantage of this solution is that, by cooperating with the two connectors 4, the lumbar support pillow can be worn on the waist of the user or fixed to a seat. Specifically, compared with the frequent disassembly and installation of traditional lumbar support products, the lumbar support pillow can be worn directly on the user's waist, and the user does not need to carry it with their hands when walking, which can significantly reduce the inconvenience during the transfer process.

[0040] When in use, the lumbar support pillow is worn on the waist in a forward "C" shape, with the lumbar contact surface 111 located on the inner ring side of the "C" shape and the seat contact surface 112 located on the outer ring side of the "C" shape.

[0041] When in a fixed position, the lumbar support pillow is fixed to the back of the seat in an inverted "C" shape, with the seat contact surface 112 located on the inner ring side of the "C" shape and the lumbar contact surface 111 located on the outer ring side of the "C" shape.

[0042] Preferably, in this embodiment, the two connectors 4 are a socket 41 and a plug 42, respectively. The socket 41 and the plug 42 are respectively located at both ends of the pillowcase 10. An adjustable cord 43 is provided between the plug 42 and the pillowcase 10. The plug 42 and the pillowcase 10 are connected by the adjustable cord 43. The length of the cord can be adjusted according to the user's waist circumference to adapt to different size wearing needs.

[0043] Preferably, in this embodiment, the pillowcase 10 is further provided with a reconnection seat 44, which is located at the same end of the pillowcase 10 as the plug 42. The plug 42 cooperates with the reconnection seat 44 to bind and limit the lumbar support pillow in the rolled-up state.

[0044] Preferably, in this embodiment, the pillowcase 10 is also provided with a hanging strap 6, which is located at the same end of the pillowcase 10 as the return seat 44. After the lumbar support pillow is rolled up, it can be conveniently carried or hung by the hanging strap 6.

[0045] The purpose of the above embodiments is to provide a detailed description of the present invention in conjunction with the accompanying drawings, so that those skilled in the art can understand the technical concept of the present invention. Within the scope of the claims of the present invention, optimization or equivalent replacement of the involved part structure, as well as combination of implementation methods in different embodiments without causing structural and principle conflicts, all fall within the protection scope of the present invention.
