[0002] Massage chair function mainly provides the massage of whole body, has two categories from the chair frame, one is that the seat pad frame and backrest frame angle can be adjusted, needs to be matched with the partition setting massage machine core, two is that the seat pad frame and backrest frame angle is constant, is equipped with L type track, so that a massage machine core can reciprocating massage up and down.L Type track is often more difficult to process into shape, and the surface still needs to have a rack fixed, considering the reliable meshing of the walking gear on the massage machine core and the curved rack, the track needs necessary design.In addition, the integrated L type track also has a defect, that is, the angle between the hip and the back is constant, whether sitting or lying is the same angle, in order to ensure the sitting posture, the lying comfort is affected.

[0003] How to provide a more reasonable technical scheme, that is, the object of the present application. SUMMARY

[0004] The utility model discloses a kind of integrated massage chair tracks suitable for lying posture curve.

[0005] The utility model technical scheme is realized as follows: a massage chair track, track main body is bent into curve by steel plate, section is groove structure and include upper groove block, vertical groove block and the lower groove bottom of providing locking rack in turn;Its characterized in that: curve track main body includes leg straight section, hip arc section, waist straight section, back arc section, shoulder neck reverse arc section and head straight section in turn, and it is tangent smooth transition between adjacent section.

[0006] In the track main body, hip arc section radius R2 is between 450mm-510mm, arc length L2 is between 180mm-230mm;Waist straight section length L3 is between 130mm-160mm;Back arc section radius R4 is between 1100mm-1130mm, arc length L4 is between 180mm-230mm;The radius R5 of shoulder neck reverse arc section is between 290mm-320mm, arc length L5 is between 125mm-160mm;Leg straight section length L1 is greater than 200mm, head straight section length L6 is greater than 50mm.

[0007] The lower groove bottom of the track main body and vertical groove block width H1 are equivalent, and no less than 40mm, both surfaces are formed with pressed concave lines along the length direction;Upper groove block width is half of lower groove bottom width;The lower groove bottom also has a reverse folding edge away from upper groove block, and the reverse folding edge width H2 is greater than 10mm;The surface of the lower groove bottom is also formed with groove hole of positioning rack.

[0008] The radius of the arc-shaped section is increased, so that the track curve is more gentle, and the adjacent sections adopt tangent smooth transition; the reasonable distribution of the track sections is not only beneficial to processing and forming, but also makes the massage mechanism run more smoothly and not jammed, especially suitable for lying state, and keeps the human body more relaxed.

[0019] 200 - rack; DETAILED DESCRIPTION

[0020] Referring to Figs. 1 to 4 , the massage chair track, the track main body 100 is bent into a curve shape by a steel plate, the cross section is a groove structure and sequentially includes the upper groove stop 101, the vertical groove stop 102 and the lower groove bottom 103 providing the locking rack; a massage chair is provided with two opposite track main bodies 100 for supporting the massage mechanism; the rack 200 is also locked on the lower groove bottom 103 of the track main body 100, so that the power gear on the massage mechanism is engaged with it to drive reciprocating walking; the upper groove stop 101 can prevent derailment and keep the reliable engagement of the gear and the rack. Among them: the curve of the track main body 100 is designed according to the human body curve, and sequentially includes the leg straight section 1, the hip arc-shaped section 2, the waist straight section 3, the back arc-shaped section 4, the shoulder and neck reverse arc-shaped section 5 and the head straight section 6, and the adjacent sections are tangent smooth transition.

[0021] The specific parameters of each section are as follows: the radius R2 of the hip arc section 2 is between 450 mm and 510 mm, and the arc length L2 is between 180 mm and 230 mm; the length L3 of the waist straight section 3 is between 130 mm and 160 mm; the radius R4 of the back arc section 4 is between 1100 mm and 1130 mm, and the arc length L4 is between 180 mm and 230 mm; the radius R5 of the shoulder-neck reverse arc section 5 is between 290 mm and 320 mm, and the arc length L5 is between 125 mm and 160 mm; the length L1 of the leg straight section 1 is greater than 200 mm, and the length L6 of the head straight section 6 is greater than 50 mm.

[0022] As a preferred scheme, the radius R2 of the hip arc section 2 is 480 mm, the arc length L2 is 207 mm; the length L3 of the waist straight section 3 is 148 mm; the radius R4 of the back arc section 4 is 1120 mm, and the arc length L4 is 384 mm; the radius R5 of the shoulder-neck reverse arc section 5 is 310 mm, and the arc length L5 is 145 mm; the length L1 of the leg straight section 1 is 240 mm, and the length L6 of the head straight section 6 is 65 mm.

[0023] Further, the lower groove bottom 103 of the track body 100 is equivalent to the width H1 of the vertical groove stop 102, and is not less than 40 mm, satisfying the necessary space for the gear and the rack 200 to mesh; the surfaces of both are formed with a pressing concave groove 104 along the length direction, improving the strength of the track body and also improving the torsion resistance; the width of the upper groove stop 101 is half of the width of the lower groove bottom 103, reducing the material cost; the lower groove bottom 103 also has a reverse folding edge 105 away from the upper groove stop, the width H2 of the reverse folding edge 105 is greater than 10 mm, improving the rigid strength of the edge; the surface of the lower groove bottom 103 is also formed with a groove hole 106 for positioning the rack, allowing the rack 200 to have a length direction adjustment allowance.
