[0037] To make the objectives, technical solutions, and effects of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Combination Figures 1 to 10 As shown, this embodiment discloses a down jacket, including a front piece 1, a back piece 2, and a collar 5.

[0040] Among them, combined Figure 1 and Figure 3As shown, the neckline position 14 of the front piece 1 and the neckline position 15 of the back piece 2 are sewn and fixed to the collar 5. The position of the collar 5 that is sewn and fixed to the neckline position 14 of the front piece 1 is called the front collar, and the position of the collar 5 that is sewn and fixed to the neckline position 15 of the back piece 2 is called the back collar, thus forming two front collars and one back collar on the collar 5, and the upper opening of the collar 5 is set to expand outward.

[0041] Combination Figure 1 As shown, collar 5 includes a front collar 51 and an inner collar 52. The front collar 51 and inner collar 52 are overlapped and sewn together for fixation, along the length of the front collar 51, i.e., along... Figure 1 In the horizontal direction shown, the upper opening of the collar 51 is provided with a first extension section 511 and a second extension section 512 at both ends, and the length of the first extension section 511 and the length of the second extension section 512 are both the seventh distance, which can be 0.2cm-0.4cm.

[0042] At this point, before sewing the outer collar and the inner collar together, the two ends of the upper opening of the outer collar are longer than the two ends of the upper opening of the inner collar by a distance of seven. When sewing the outer collar and the inner collar together, the first extension segment and the second extension segment of the outer collar are sewn and fixed to the inner collar in the form of pleats, that is, the outer collar and the inner collar are connected by pleats so that after the outer collar and the inner collar are sewn together, the length of the outer collar and the length of the inner collar are equal.

[0043] Furthermore, the back neckline 513 of the face collar 51 Figure 1 A third extension segment is provided in the horizontal direction, the length of which is the eighth distance, specifically 0.6cm-0.9cm, and the third extension segment connects to the upper back neckline 521 of the inner collar with a pleat. Simultaneously, along the length of the outer collar 51, a fourth extension segment 510 and a fifth extension segment 514 are respectively provided at both ends of the lower edge of the outer collar 51, the lengths of which are the ninth distances, specifically 0.3cm-0.6cm, and the fourth extension segment 510 and the fifth extension segment 514 connect to the pleat of the inner collar 52.

[0044] In the down jacket of this embodiment, by setting a first extension section and a second extension section at both ends of the upper opening of the collar, a third extension section at the upper back opening of the collar, and a fourth extension section and a fifth extension section at both ends of the lower opening of the collar, and connecting them to the inner collar for pleating, the collar and inner collar can be evenly spaced inside and out, the collar circumference is smooth with minimal bulging, and the collar can naturally encircle the neck. At the same time, the collar not only increases the forward tilt of the down jacket relative to the user's chin to accommodate the chin inside the collar without pressing against it, but also increases the amount of coverage of the back of the user's head, reducing friction between the collar and the user's hair, thereby improving wearing comfort and reducing collar wear, and thus improving the wear resistance and wearing comfort of the down jacket.

[0045] Specifically, in this embodiment, the first extension segment 511 is connected to one front neckline 522 of the inner collar 52 with a pleated seam, the second extension segment 512 is connected to the other front neckline 523 of the inner collar 52 with a pleated seam, and the third extension segment is connected to the back neckline 521 of the inner collar 52 with a pleated seam, thereby improving the uniformity of the stitching connection between the first extension segment and the inner collar, as well as between the second extension segment and the inner collar, and thus achieving the technical effect of improving the connection balance between the outer collar and the inner collar.

[0046] In addition, the fourth extension segment 510 is evenly sewn to one front collar bottom edge 524 of the inner collar 52, and the fifth extension segment 514 is evenly sewn to the other front collar bottom edge 525 of the inner collar 52. The even sewing improves the uniformity of the stitching between the fourth and fifth extension segments and the inner collar, and improves the flatness of the stitching connection between the outer collar and the inner collar, thereby enhancing the aesthetics of the collar.

[0047] Combination Figure 2 and Figure 4 As shown, in this embodiment, the down jacket also includes a facing 6 and a zipper 16. The zipper 16 is located between the facing 6 and the front panel 1. The side of the zipper 16 closest to the user's skin is sewn to the facing 6, and the side of the zipper 16 furthest from the user's skin is sewn to the front panel 1. The facing 6 has a sixth extension 63 located tenth of a distance downwards from the intersection of the neckline 62 and the front placket 64. The length of this tenth distance can be 9cm-11cm. The zipper 16 also has a seventh extension 17 located tenth of a distance downwards from the neckline 14 of the front panel. Figure 2 In the vertical direction shown, the length of the sixth extension segment 63 is the eleventh distance, and the length of the eleventh distance can be 0.3cm-0.5cm. The length of the seventh extension segment 17 is the twelfth distance, and the length of the twelfth distance can be 0.1cm-0.2cm. The sixth extension segment 63 is connected to the zipper 16, and the seventh extension segment 17 is connected to the front piece 1.

[0048] By incorporating a sixth extension section on the hanging surface and a seventh extension section on the zipper, and connecting the sixth extension section to the zipper's pleats and the seventh extension section to the front panel's pleats, when the zipper is opened at this pleat connection point, the pleats formed by the sixth and seventh extension sections allow the collar to move smoothly away from the user's neck, while simultaneously allowing the collar to naturally fold outwards. When the zipper is closed at this pleat connection point, the collar gradually expands outwards and naturally moves away from the user's chin, thereby improving wearing comfort and making the user appear more energetic.

[0049] Preferably, both the outer and inner collars are three-dimensionally cut, so that the curves of the front and back necklines are on the same oblique plane. Based on this, the collar can be presented in a stand-up collar style, naturally covering the neck. At the same time, the collar is less prone to twisting, and the rounded upper back neckline is less likely to form sharp angles, thus improving the fit between the collar and the user's neck, and further enhancing both user comfort and aesthetics.

[0050] In addition, combined Figure 6 As shown, in this embodiment, the front placket circumference 13 of the front piece 1 has an outwardly protruding section. Specifically, the outwardly protruding section is three-dimensionally cut, such that the ratio of its radial dimension to its weft dimension is 2:3. Simultaneously, the radial position of the outwardly protruding section is connected to the zipper 16 via a pleated connection, forming a shape as shown... Figure 6 The convex arc shape of the front placket waistband shown improves the fit between the front placket waistband and the user, accommodating users with a belly, thereby enhancing the wrapping effect on the user's belly and making the user feel relaxed and not tight around the belly.

[0051] In addition, combined Figure 6 As shown, in this embodiment, the zipper 16 is located between the hanging surface 6 and the front piece 1 and connects them respectively. Before sewing, one end of the hanging surface 6, one end of the zipper 16, and one end of the front piece 1 (specifically along...) Figure 6 The tops shown are all aligned, and the other ends of the faceplate 6, the other end of the zipper 16, and the other end of the front piece 1 (specifically along...) Figure 6 The lengths of the bottom ends shown increase sequentially. The other end of the zipper 16 is longer than the other end of the hanging surface 6 by a third distance, and the other end of the front piece 1 is longer than the other end of the hanging surface 6 by a sixth distance. The third distance can be 0.6cm-0.8cm, and the sixth distance can be 1.8cm-2.2cm.

[0052] The zipper 16 has a first wrinkle-reducing section, which is located above the belly area of ​​the noodle 6, and the first wrinkle-reducing section extends along... Figure 4 The vertical bottom end shown is four distances away from the belly circumference of the noodle 6, and the first wrinkle section is along... Figure 4The vertical length shown is half of the third distance, and the first wrinkle-feeling section is connected to the noodle 6 for wrinkle-feeling. A second wrinkle-feeling section is provided on the zipper 16. The second wrinkle-feeling section is located below the belly area of ​​the noodle 6, and the top of the second wrinkle-feeling section is a fifth distance away from the belly area of ​​the noodle 6. The length of the second wrinkle-feeling section is half of the third distance, and the second wrinkle-feeling section is connected to the noodle 6 for wrinkle-feeling.

[0053] Meanwhile, a third wrinkle-retaining section is provided on the front piece 1. This third wrinkle-retaining section is located above the belly area of ​​the noodle 6, and extends along... Figure 4 The bottom edge of the vertical section shown is a fourth distance from the belly area of ​​the hanging surface 6. The length of the third wrinkle section is half of the sixth distance, and the third wrinkle section is wrinkle-connected to the zipper 16. A fourth wrinkle section is provided on the front piece 1, located below the belly area of ​​the hanging surface 6. The top edge of the fourth wrinkle section is a fifth distance from the belly area of ​​the hanging surface 6. The length of the fourth wrinkle section is half of the sixth distance, and the fourth wrinkle section is wrinkle-connected to the zipper 16. Specifically, the length of the fourth distance can be within the range of 9cm-11cm, and the length of the fifth distance can also be within the range of 9cm-11cm.

[0054] After the wrinkle-absorbing connection, the other ends of the facing 6, the other end of the zipper 16, and the other end of the front piece 1 are all aligned. This allows the facing, zipper, and front piece to form an outward convex shape at the belly area, with the degree of convexity increasing from the inside to the outside. This also complements the shape of the outward convex section, thereby further enhancing the three-dimensionality of the down jacket at the belly area and creating a natural and comfortable fit for the user's stomach.

[0055] Combination Figure 3 As shown, preferably, in this embodiment, the down jacket also includes two middle panels 4. Correspondingly, the front panel 1 has two panels, one side of the back panel 2 is sewn to one side of one middle panel 4, and the other side of one middle panel 4 is sewn to one front panel 1. The other side of the back panel 2 is sewn to one side of another middle panel 4, and the other side of another middle panel 4 is sewn to another front panel 1. The middle panels can increase the size of the down jacket at the side waist position, increasing the accommodation for the side waist and improving the three-dimensionality of the down jacket, thereby enhancing the wrapping and accommodation effect of the down jacket at the side waist position.

[0056] Furthermore, in this embodiment, combined with Figure 3As shown, the waistline of the front piece is tapered at the first distance D1, which can be 0.8cm-2cm, for example, a 1cm tapering at the front waistline. The waistline of the back piece is tapered at the second distance D2, which can be 2cm-3cm, for example, a 2.5cm tapering at the back waistline. This enhances the waistline definition of the back piece while also subtly tapering the waistline of the front piece, thereby improving the fit of the down jacket, conforming to the user's waistline, and enhancing the aesthetics of the waist.

[0057] Combination Figure 4 and Figure 5 As shown, the down jacket also includes two sleeves 3. Sleeves 3 are sewn and secured to an armhole position 11 on the front panel, an armhole position on the middle panel, and an armhole position 21 on the back panel, respectively. Sleeves 3 are flat-shoulder sleeves, and the center line angle A of sleeve 3 is 20 degrees.

[0058] This sleeve design not only conforms to the user's arm lines but also ensures sufficient room for movement under the armpits. Specifically, the user's arms rotate to the side to meet the armpits. Figure 1 As shown, when the arms are rotated 180 degrees, and when both arms rotate 360 ​​degrees with the shoulder joint as the rotation point, the jacket will not let in wind as the arms move upward, thereby improving the user's arm rotation flexibility and the warmth of the down jacket during the arm rotation.

[0059] Preferably, in this embodiment, combined with Figure 3 As shown, the shoulder line slope α of the front panel 1 is 21 degrees. This is to adapt to the average front shoulder slope of 19-22 degrees for the average Chinese person, thereby improving the fit between the down jacket and the front shoulder area. This ensures that the weight of the garment is evenly distributed on the user's front shoulder, thus enhancing the user's comfortable wearing experience. It also prevents the front shoulder from being too small or too large, which would prevent the down jacket from fitting the user's front shoulder completely, resulting in uneven weight distribution and reduced wearing comfort.

[0060] Meanwhile, the total shoulder slope of the back piece is set at 21 degrees, resulting in an average angle of 21 degrees between the front and back pieces, aligning with the average shoulder slope angle of 21 degrees for the average Chinese person. Specifically, the shoulder line slope β of the back piece is set at 18.5 degrees, with the remaining 2.5 degrees transferred to the back armhole. This design allows the back shoulder line to slope towards the front, conforming to the natural shoulder line of the human body from the neck to the arm, tilting forward. This improves the fit between the shoulder line and the shoulder after the front and back pieces are joined, ensuring the weight of the down jacket is evenly distributed across the user's back shoulder area, thus enhancing comfort and ease of wear.

[0061] Specifically, in combination Figure 3As shown, in this embodiment, the back piece 2 includes a back panel 23 and a lower back piece 24. The remaining 2.5 degrees are transferred to the connection point between the back panel and the lower back piece, with the first connection point of the back panel 23 and the first connection point of the lower back piece 24 coinciding and serving as the coincidence point 25. The angle between the line connecting the coincidence point 25 and the second connection point 231 of the back panel 23 and the line connecting the coincidence point 25 and the second connection point 241 of the lower back piece 24 is γ, where γ is 2.5 degrees. This not only improves the uniformity of the force on the user's shoulders but also allows a back piece dart to be formed between the back panel and the lower back piece. This not only further improves the slim fit of the back piece but also enhances the smoothness of the shoulder line, preventing diagonal lines between the shoulder line and the armhole of the back piece, which would affect the aesthetics of the down jacket.

[0062] Of course, in other embodiments, depending on the design of the down jacket, the front and back pieces can also be designed as a single piece.

[0063] In addition, combined Figure 7 As shown, in this embodiment, the front piece 1, middle piece 4, back piece 2, and sleeve 3 each include a first lining fabric 7 and a second lining fabric 8. The first lining fabric 7 and the second lining fabric 8 are overlapped and connected at multiple points to form multiple independent down filling cavities. This can improve the uniformity of down filling and prevent down from piling up and affecting the warmth of the down jacket.

[0064] Among them, combined Figure 7 and Figure 8 As shown, an adhesive strip 10 is provided at the connection position of the first lining fabric 7 and the second lining fabric 8. For example, an adhesive strip with a thickness of 0.05cm-0.1cm and a width of 0.3cm-0.5cm is used. The adhesive strip is bonded and fixed to the first lining fabric 7 and the second lining fabric 8 respectively by a pressing machine. This can improve the tightness and firmness of the connection between the first lining fabric and the second lining fabric, and avoid the low connection strength at multiple points between the first lining fabric and the second lining fabric, which would allow the independent down filling cavities to communicate with each other, causing the down to accumulate in one place and affecting the warmth of the down jacket.

[0065] Furthermore, in combination Figure 9 As shown, the front panel also includes a cut piece 9. The cut piece 9 is arranged to overlap with the first inner fabric, which can further increase the difficulty of down feathers emerging, thereby improving the durability and warmth of the down jacket.

[0066] The cut piece 9, the first lining fabric 7, and the second lining fabric 8 are sewn together by quilting 100, and the quilting 100 is located at the connection position of the first lining fabric 7, the adhesive strip 10, and the second lining fabric 8. This not only improves the tightness of the connection between the cut piece, the first lining fabric, and the second lining fabric, but also prevents the aging of the adhesive strip from affecting the tightness of the connection between the first lining fabric and the second lining fabric, thereby further improving the warmth of the down jacket.

[0067] The above description is merely a specific embodiment of the present invention. Under the teachings of the present invention, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present invention, and the scope of protection of the present invention should be determined by the scope of the claims.
