[0002] The design of the back piece of existing clothing usually focuses on aesthetics and basic functions, lacking effective support for the waist and back. For people who need to maintain a fixed posture for a long time in daily life or work (such as office workers, drivers, shooting athletes, patients with waist injuries, etc., and appropriate fabrics are required), existing clothing cannot relieve the pressure on the waist and back and is prone to cause discomfort. Therefore, there is an urgent need for a back structure and a manufacturing method that can provide support without affecting the comfort of movement. Summary of the Invention

[0003] The main object of the present invention is to propose a back structure with support force and a manufacturing method thereof, which can effectively solve the problems in the background art.

[0005] A back structure with support force includes a back piece, and a support component is sewn in the back piece. The support component includes two first elastic rigid strips. The two first elastic rigid strips are symmetrically arranged along the back center line of the back piece and respectively extend from the shoulder lines on both sides of the back piece to the hem. Two second elastic rigid strips are connected between the two first elastic rigid strips, and the two elastic rigid strips are located at the waist position of the back piece.

[0006] Preferably, the two second elastic rigid strips are inclined and parallel to each other.

[0007] Preferably, two third elastic rigid strips are respectively added upward along the first elastic rigid strip at the connection of the two second elastic rigid strips and one side of the first elastic rigid strip, and two third elastic rigid strips are respectively added downward along the first elastic rigid strip at the connection of the two second elastic rigid strips and the other side of the first elastic rigid strip.

[0010] S2: On the right side of the back panel, use the same method as in step S1 to locate points F, G, H, I, and J. Points F, G, H, I, and J are symmetric to points A, B, C, D, and E along the back center line.

[0011] S3: Connect points A, B, C, D, and E, and name this connecting line L 1 , and similarly connect points F, G, H, I, and J, and name this connecting line L 2 ;

[0032] Embodiment

[0033] Referring to Figure 6 , the present invention provides a back structure with support force, including a back piece 1, in which a support component is sewn. The support component includes two first elastic rigid strips 11. The two first elastic rigid strips 11 are symmetrically arranged along the rear center line of the back piece 1 and extend from the shoulder lines on both sides of the back piece 1 to the hem respectively. Two second elastic rigid strips 12 are connected between the two first elastic rigid strips 11, and the two elastic rigid strips 12 are located at the waist position of the back piece 1.

[0034] For the back structure of the present invention, the two first elastic rigid strips 11 and the two second elastic rigid strips 12 effectively support the human waist and back. For people who maintain a fixed posture for a long time, it can reduce the pressure on their waist and back and avoid discomfort.

[0035] In a specific embodiment, the two second elastic rigid strips 12 are inclined and parallel to each other.

[0036] In a specific embodiment, at the connection of the two second elastic rigid strips 12 and one side of the first elastic rigid strip 11, two third elastic rigid strips 13 are respectively added upward along the first elastic rigid strip 11. At the connection of the two second elastic rigid strips 12 and the other side of the first elastic rigid strip 11, two third elastic rigid strips 13 are respectively added downward along the first elastic rigid strip 11. The third elastic rigid strips 13 are located on the first elastic rigid strip 11, forming a double-layer support structure at this place to enhance the support strength.

[0037] The present invention also provides a manufacturing method for a back structure with support force, including the following steps:

[0038] S1: Referring to Figure 1, on the left side of the back piece, select the positioning point A at the 1 / 2 position of the shoulder line, select the positioning point B at the highest point of the scapula, select the intersection point C of the 1 / 2 position between the center back and the side seam and the waistline (WL), select the intersection point D of the 1 / 2 position between the center back and the side seam and the hip line (HL), draw a perpendicular line from point D to the hem, and intersect the hem at point E;

[0039] It should be noted that everyone's body structure is different. Therefore, during the cutting and production process of the back piece, it is necessary to determine the positions of the shoulder line, the highest point of the scapula, the waistline, and the hip line according to the body structure to ensure the fit and comfort of the clothing. This step selects and locates points according to the positions of the shoulder line, the highest point of the scapula, the waistline, and the hip line already determined in the back piece.

[0040] S2: On the right side of the back piece, use the same method as in step S1 to locate points F, G, H, I, and J. Points F, G, H, I, and J are symmetrical to points A, B, C, D, and E along the center back line;

[0041] S3: Connect points A, B, C, D, and E, and smooth the line from A to D. Name this connecting line L 1 , similarly connect points F, G, H, I, and J, and smooth the line from F to J. Name this connecting line L 2 ;

[0042] S4: Refer to Figure 2 , draw a parallel line to the waistline (WL) at a / 2 below the waistline (WL) vertically at point C, and the intersection point with L 1 is defined as point K. Draw a parallel line to the hip line (HL) at a above the hip line (HL) vertically at point I, and the intersection point with L 2 is defined as point L. Connect the straight line KL, where a is 1 / 3 of the distance between the waistline (WL) and the hip line (HL);

[0043] S5: Draw a parallel line to the waistline (WL) at a / 2 above the waistline (WL) vertically at point H, and the intersection point with L 2 is defined as point M;

[0044] S6: Draw a parallel line to the straight line KL at point M and intersect L1 at point N, and connect the straight line MN;

[0045] S7: Refer to Figure 4 , use L 1 , L 2 , the straight line KL, and the straight line MN as the dividing lines to cut and release the seams, and divide the back piece into 5 pieces;

[0046] S8: Refer to Figure 5 , sew the 5 cut back pieces, and add elastic hard strips at the seam allowances. In this step, the elastic hard strips are two first elastic hard strips 11 and two second elastic hard strips 12;

[0047] S9: Refer to Figure 3 and Figure 6 , at point K and point N, add an elastic rigid strip with a length of 2a / 3 along L 1 upward, and at point L and point M, add an elastic rigid strip with a length of 2a / 3 along L 2 downward. The elastic rigid strip with a length of 2a / 3 in this step is the third elastic rigid strip 13.

[0048] The manufacturing method of the back structure of the present invention reasonably plans the length and position of the elastic rigid strip according to the positions of the shoulder line, the highest point of the scapula, the waist line, and the hip line in the back piece, so that the support of the elastic rigid strip is more in line with the ergonomic design of clothing, so that while the back structure can provide effective support, it does not affect the comfort of human activities.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
