[0057] The main body 20 of a multifunctional lumbar pillow can have various variations in structure depending on structural variations and the addition or subtraction of components. This specification lists one variation of the main body 20. Figure 14 ), Main variant structure two ( Figure 17 A multifunctional lumbar pillow, which has various structural variations depending on the addition or subtraction of components, is described in this specification as having one such variation. Figure 20 The structural form of ) is described in detail below.

[0058] Please see Figure 1 , Figure 5 , Figure 6 , Figure 14 , Figure 15 , Figure 17 , Figure 20 .

[0059] A multifunctional lumbar pillow can be used in various settings beyond just chairs, such as sofas, car seats, and bedside tables. It can be placed on any surface or appliance where lumbar support is needed. The multifunctional lumbar pillow comprises a main body 20, a fixing sleeve, a tension strap, a fixing strap, a shell, a motor, an eccentric wheel, a cloth bag, a battery, a frame, a power cord, a connector, a power switch, a rotary motor, a rocker arm, elastic components, an extension frame, a pivot pin, ball rollers, an elastic diaphragm, and an outer cover.

[0060] The backrest 10.1 and seat surface 10.2 of seat 10 have a certain angle of inclination. A multi-functional lumbar support is placed on seat surface 10.2, with the left lumbar support's inclined surface 20.5 and the right lumbar support's inclined surface 20.9 resting against seat surface 10.2, and the backrest 20.1, left lumbar support 20.2, and right lumbar support 20.6 resting against the backrest 10.1. X is the angle between the left lumbar support and its inclined surface, and also the angle between the right lumbar support and its inclined surface. X is greater than 90 degrees and is close to the angle of inclination between the backrest 10.1 and seat surface 10.2 of seat 10. The outer contour of the main body 20 matches the outer contour of the seat 10, which maximizes the contact area between the left pillow 20.2, the right pillow 20.6 and the seat back 10.1, and maximizes the contact area between the left pillow inclined surface 20.5, the right pillow inclined surface and the seat surface 10.2, thereby increasing the friction of the main body 20 on the seat 10 and preventing the main body 20 from slipping off the seat 10 or the seat where a person is sitting.

[0061] The left loop 23.1 is fitted onto the left headrest 20.2, the right loop 23.2 is fitted onto the right headrest 20.6, and the elastic band 23.3 is fitted onto the chair back 10.1. The elastic function of the elastic band 23.3 allows the fixing band 23 to fix the main body 20 onto the chair back 10.1 of various styles.

[0062] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 15 .

[0063] A multifunctional lumbar pillow body 20 is provided with a rear pillow 20.1, a left pillow 20.2, and a right pillow 20.6. The left pillow 20.2 is connected to the left side of the rear pillow 20.1, and the right pillow 20.6 is connected to the right side of the rear pillow 20.1. When a person sits in a chair, the left pillow 20.2 supports the left side of the person's waist, and the right pillow 20.6 supports the right side of the person's waist. The height of the left pillow 20.2 and the right pillow 20.6 supporting the rear pillow 20.1 reaches the height of the person's waist when sitting in a chair, which facilitates the support of the lower back when the person is sitting in a chair. The left pillow 20.2 has a left pillow curved surface 20.3, a contact block 20.4, and a left pillow inclined surface 20.5; the right pillow 20.6 has a right pillow curved surface 20.7, a contact block 20.8, and a left pillow inclined surface 20.9. The interior of the main body 20 is a filling layer 20.B, which includes soft, retaining materials, liquids, and gases. The sheath layer 20.C is a soft, leak-proof material, including leather, rubber, and textiles, covering the outer layer of the main body 20. The curvature corresponding to the left pillow curved surface 20.3 and the right pillow curved surface 20.7 is set to Y, and the value of Y is less than 90° (e.g., ...). Figure 6 The arc Y between the starting point A and the ending point B of the arc surface 20.3 of the left occipital and the arc Y between the starting point A and the ending point B of the arc surface 20.7 of the right occipital are both less than 90°. This means that the cross-sections of the left occipital 20.2 and the right occipital 20.6 are elliptical, trapezoidal, or circular with an angle less than 90°. The outer contour of the main body 20 is formed by bending an elliptical, trapezoidal, or cylindrical object with an angle less than 90°. When the left occipital arc surface 20.3 and the right occipital arc surface 20.7 are compressed at the waist of the human body, the left occipital arc surface 20.3 and the right occipital arc surface 20.7 gradually approach the waist of the human body from the left and right sides according to the contour of the human body.

[0064] The angles between the left pillow 20.2 and its inclined surface 20.5, and between the right pillow 20.6 and its inclined surface 20.9, are set as X, with a value greater than 90 degrees. This maximizes the contact area between the left pillow 20.2, right pillow 20.6 and the seat back 10.1, and between the left pillow inclined surface 20.5, right pillow inclined surface 20.9 and the seat surface 10.2, increasing the friction of the main body 20 on the seat 10 to prevent it from slipping off the seat or from where a person is sitting. The fixing sleeve 21 has multiple rows of male hidden buckles 21.1, and two fixing sleeves 21 are respectively fitted and fixed onto the left pillow 20.2 and right pillow 20.6. The tension band 22 has a row of female snap fasteners 22.1 at each end, which respectively engage with the male snap fasteners 21.1 on the fixing sleeve 21 fixed on the left pillow 20.2 and the fixing sleeve 21 fixed on the right pillow 20.6 to fix the distance between the left pillow 20.2 and the right pillow 20.6; and the female snap fasteners 22.1 on the tension band 22 can be engaged with male snap fasteners 21.1 at different positions on the fixing sleeve 21 to adjust the distance between the left pillow 20.2 and the right pillow 20.6 to suit different people's body types. The fixing strap 23 is equipped with a left loop 23.1, a right loop 23.2, and an elastic strap 23.3. The left loop 23.1 is fitted onto the left headrest 20.2, the right loop 23.2 is fitted onto the right headrest 20.6, and the elastic strap 23.3 is fitted onto the seat back 10.1. The elasticity of the elastic strap 23.3 allows the fixing strap 23 to fix the main body 20 to various styles of seat backs.

[0065] Please see Figure 10 , Figure 11 , Figure 12 , Figure 13 .

[0066] The frame 35 is characterized by a rear support rod 35.1, a left support rod 35.2, a rear support plate 35.3, a right support rod 35.4, and a right support plate 35.5. It is placed inside the main body 20 and serves as a support and fixing component for the filling layer 20.B, the vibrator 300, and the massager 400 inside the main body 20.

[0067] The vibrator 300 includes a housing 30, a motor 31, and an eccentric wheel 32. The housing 30 has an end cap, the motor 31 has a motor shaft 31.1, and the eccentric wheel 32 has a shaft hole 32.1. The eccentric wheel shaft hole 32.1 is fixedly connected to the motor shaft 31.1. The motor 31 is fixedly placed inside the housing 30, and the end cap 30.1 seals it, fixing the motor's position within the housing. If the filling layer 20.B is filled with liquid or gas, the housing 30 is made insulated and sealed. A cloth bag 33 is fitted over the vibrator 300 and fixed to the frame 35. When the motor 31 is energized and rotates, the imbalance caused by the rotation of the eccentric wheel 32 vibrates the housing 30, which is fixed to the motor 31. The vibration of the housing 30 is transmitted to the filling layer 20.B and then to the waist area of ​​the user. The flexibility of the cloth bag 33 buffers the vibration generated by the vibrator 300, preventing the vibration from being directly transmitted to the frame 35. The vibrators, housed in a cloth bag, are placed inside the main body 20, specifically at the back of the head (20.1), the left side of the head (20.2), and the right side of the head (20.6).

[0068] The massager 400 includes a rotary motor 40, a rocker arm 41, an elastic element 42, an extension frame 43, a shaft pin 44, and a ball roller 45, all housed within an outer casing 47, which is fixedly connected to a frame 35. The rotary motor 40 features a motor shaft 40.1; the rocker arm 41 features an outer shaft hole 41.1 and an inner shaft hole 41.2; the extension frame 43 features an extension shaft 43.1, a support 43.2, and a shaft hole 43.3; and the ball roller features a shaft hole 45.1. The outer shaft hole 41.1 of the rocker arm is fixedly connected to the motor shaft 40.1. The elastic element 42 is built into the inner shaft hole 41.2 of the rocker arm. The extension shaft 43.1 passes through the inner shaft hole 41.2 of the rocker arm and forms a sliding connection with the inner shaft hole 41.2. The shaft pin 44 passes through the extension frame shaft hole 43.3 and the ball roller shaft hole 45.1 and forms a rotatable connection with the extension frame shaft hole 43.3 and the ball roller shaft hole 45.1. The rotary motor 40 is fixedly placed inside the outer casing 47. The elastic diaphragm 46 is fixedly connected to the outer casing 47 and placed between the ball roller and the filling layer 20.B to prevent the ball roller 45 from directly contacting the filling layer 20.B. If the filling layer 20.B is filled with liquid or gas, the outer casing 47 and the diaphragm 46 are made to be insulated and sealed. When the rotary motor 40 rotates, it drives the rocker arm 41, elastic element 42, extension frame 43, shaft pin 44, and ball roller 45 to rotate within the outer casing 47 and the diaphragm 46. The extension frame 43 extends outward under the elastic force of the elastic frame 42. When the ball roller 45 touches the filling layer 20.B at the waist position of the human body, the filling layer 20.B is compressed. Through the diaphragm 46 layer, the extension shaft 43.1 of the extension frame is axially pressed into the inner shaft hole 41.2 of the rocker arm 41. The elastic element 42, placed on the inner shaft hole 41.2 of the rocker arm, is compressed by the extension shaft 43.1, and the reverse elastic force is increased. It is applied in the opposite direction to the extension shaft 43.1, the ball roller 45, and then to the waist of the human body, producing a pushing and massaging effect on the waist.

[0069] The power lines 36 of motor 31 and rotary motor 40 are routed around frame 35 and connected in parallel to connector 37. Battery 34 is installed in battery holder 20.A, connector 37 is inserted into battery socket 34.1, and power switch 38 is installed on battery 34. When power switch 38 is turned on, vibrator 300 and massager 400 start working; when power switch 38 is turned off, vibrator 300 and massager 400 stop working.

[0070] Please see Figure 14 , Figure 15 , Figure 16 .

[0071] The main body 20 variant structure also features a posterior occipital 20.1, a left occipital 20.2, and a right occipital 20.6, but the arc Y corresponding to the arc surface 20.3 of the left occipital ... Figure 16This refers to the radian Y corresponding to the distance between the starting point A and the ending point B of the left occipital arc surface 20.3, and the radian Y corresponding to the distance between the starting point A and the ending point B of the right occipital arc surface 20.7. The value of Y is 180°, meaning that the cross-section of the main body 20 variant structure one is circular, and the outer contour of the main body 20 variant structure one is formed by bending a cylinder. (Joining) Figure 6 The arc Y corresponding to the left occipital arc surface 20.3 and the right occipital arc surface 20.7 of the main body 20 has a value of 30°, meaning that the value of Y can be between 30° and 180°. When the human waist compresses the left occipital arc surface 20.3 and the right occipital arc surface 20.7, the left occipital arc surface 20.3 and the right occipital arc surface 20.7 gradually approach the human waist from the left and right sides according to the contour of the human body.
