Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle interior decoration, in particular to a support structure at a bending position of a suture line of a seat cover. Background Art
[0002] In the existing seat cover bending part, the seam without decorative lines and quilting lines is relatively soft when there is no hard support. When the seam is bent in an arc, the fabric inside the seam that is not constrained or difficult to constrain will be twisted left and right or up and down. The bending shape is not the predetermined arc or shape, and it is impossible to achieve a stable shape through finishing methods. The severely distorted seam leads to a snake-like bending of the stitching line, which is judged as a quality defect. The seam of the cover temporarily stuck by the plastic part or foam needs manpower to fold the seam and then insert it into the gap between the cover and the foam or plastic part, which consumes a lot of manpower. In addition, the temporarily stuck seam of the cover will be displaced and fall out when encountering external force. The unconstrained seam will bend after the movement, and the bent seam will lead to bulges, wrinkles, and twisted stitching lines on the seat surface. Utility Model Content
[0003] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a support structure at the bending position of the seat cover seam line which can not only play a supporting role but also constrain the seam edge of the cover and guide the seam edge of the cover to bend according to a predetermined trajectory.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a support structure at the bending position of the seam line of a seat cover, comprising two layer covers, the two layer covers are sewn together by the seam line of the cover, and a support member is arranged at the bending position along the seam line of the cover, the hardness of the support member is greater than the hardness of the cover and can be bent, the support member is sewn to the outside of the two overlapping layer covers, the seam line of the support member is close to the side of the edge of the cover, and the support member shall not cross the seam line of the cover, the support member is arranged along the extension direction of the seam line of the cover and is consistent with the length at the bending position, so that the seam line of the cover passes through the support member at the bending position without bulging, wrinkles or seam twisting.
[0005] Preferably, the support member is a sheet support member with a width of 5 mm to 8 mm and a thickness of 0.5 mm to 1.2 mm. The suture line of the support member is located on the center line of the support member, and a margin of 1 to 3 mm is left between the edge of the support member and the suture line of the face cover.
[0006] Preferably, the support member is made of PP, PE, rubber or ABS plastic.
[0007] Preferably, the support member is a narrow strip support member with a cylinder at one end; the outer diameter of the cylinder is 1.6-3.5 mm, the width of the narrow strip is 7 mm-9 mm, and the thickness is 0.8-1.2 mm. The suture line of the support member is located at the connection position between the cylinder and the narrow strip, so that the cylinder is just pressed on the suture line of the face cover, and the suture line of the round tube is 1-3 mm away from the suture line of the face cover.
[0008] Preferably, the support member is made of PP, PE or rubber.
[0009] Preferably, the cylinder is a hollow cylinder with an inner hollow diameter of 0.5+ / -0.05 mm.
[0010] Preferably, the face cover is made of genuine leather, microfiber, polyurethane or PVC needle punching.
[0011] The beneficial effects of the utility model are as follows: a support member with a hardness greater than that of the face cover is used to sew the support member with a hardness greater than that of the face cover to the portion of the seat that needs to be bent, and the support member with a hardness greater than that of the face cover is sewn to the seam edge of the face cover. On the one hand, it plays a supporting role, and on the other hand, it can constrain the seam edge of the face cover and guide the seam edge of the face cover to perform bending movements according to a predetermined trajectory. The utility model is suitable for structures in which the seat foam hardness is too low and the support is weak, or there is no support in part or at all. The utility model has low cost, is easy to operate, and has a long-lasting effect. The face cover itself carries the supporting and restraining functions, and provides an optional new face cover structure for seat design. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] like Figure 1 , 4 As shown, a support structure at the bending position of the seat cover stitching line is mainly composed of two layer covers 1, wherein the two layer covers 1 are stitched together through the cover stitching line 3, and a support member 2 is arranged at the bending position along the cover stitching line 3, which plays a supporting role and constrains the seam edge of the cover 1 and guides the seam edge of the cover 1 to bend along a predetermined trajectory.
[0021] The hardness of the support 2 is greater than that of the face cover 1 and can be bent, wherein the face cover 1 is made of leather, microfiber, polyurethane or PVC needle-punched, and the Rockwell hardness of the support 2 is preferably not less than 75. The support 2 is sewn on the outside of the seam edge of the two overlapping face covers 1, the support suture line 4 is close to the side of the face cover edge, and the support 2 shall not cross the face cover suture line 3. The support 2 is arranged along the length extension direction of the face cover suture line 3 and is consistent with the length at the bending position, so that the face cover suture line 3 passes through the support 2 at the bending position without bulging, wrinkles or suture twisting.
[0022] like Figure 2 , 3 As shown, when the support member 2 is a sheet support member, the sheet support member has a width of 5 mm to 8 mm and a thickness of 0.5 mm to 1.2 mm, the support member suture line 4 is located on the center line of the support member 2, and a margin of 1 to 3 mm is left between the edge of the support member 2 and the face cover suture line 3, so as to ensure that when bending, the support member 2 is prevented from tightening the face cover 1, causing the face cover suture line 3 to be crooked and twisted. The material of the support member 2 can be PP, PE, rubber or ABS plastic.
[0023] like Figure 5 , 6 As shown, when the support member 2 is a narrow strip support member with a cylinder at one end, the outer diameter of the cylinder is 1.6-3.5 mm, the width of the narrow strip is 7 mm-9 mm, and the thickness is 0.8-1.2 mm. The support member suture 4 is located at the connection position between the cylinder and the narrow strip, so that the cylinder is just pressed on the face sleeve suture 3, and the suture of the round tube has a margin of 1-3 mm from the face sleeve suture 3. When bending, the face sleeve suture 3 is guided by the cylinder to bend. The material of the support member 2 is PP, PE or rubber. In order to realize the bending of the cylinder and ensure that the cylinder has a certain structural hardness, the cylinder is a hollow cylinder with an inner hollow diameter of 0.5+ / -0.05 mm.
[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
