Description

Technical Field

[0001] This utility model relates to the technical field of seat structure, and specifically to a seat with a liner. Background Technology

[0002] Most existing car seats have ventilation functions, which are achieved by a fan suspended behind the seat. However, when a seat cover is installed, the fan's rotation can cause the cover to stick to it, affecting ventilation performance. Furthermore, the fan's placement means that when touching the seat back, the fan can easily be felt, creating a foreign object sensation. Alternatively, the fan may extend beyond the surface of the seat's foam, causing unevenness on the cover's surface. Therefore, existing technologies often use a liner between the fan and the cover to shield the fan, preventing it from sticking to the cover, reducing the foreign object sensation, and improving the cover's flatness. Additionally, seats without fans also use a liner to make the seat back smoother.

[0003] Existing seat covers use hook-and-loop fasteners sewn onto the seat cover to secure the lining. Typically, each lining requires at least two hook-and-loop fasteners. This method involves tedious steps in sewing the hook-and-loop fasteners, and in order to hide the seam ends of the fasteners, a horizontal seam is set on the seat cover. However, the exposed horizontal seam also affects the aesthetics of the seat cover. In addition, the use of hook-and-loop fasteners also has the problem of high cost. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a seat with a lining, which solves the problems of cumbersome sewing steps, the impact of horizontal seam lines on aesthetics, and high cost of the existing method of fixing the lining with hook and loop fasteners.

[0046] See Figure 1 This utility model provides a seat with a liner. The liner is supported and fixed by designing the seat cover structure, resulting in advantages such as simple sewing, low cost, and a smooth seat cover appearance. The seat with a liner according to this utility model will be described below with reference to the accompanying drawings.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0048] See Figure 1 This is a schematic diagram of the inner fixing liner of the seat cover structure with liner of this utility model. (See attached diagram.) Figure 5 This diagram shows a structural schematic of the seat cover structure with a liner according to the present invention. (See attached diagram.) Figure 6 The image shows an exploded exploded structural diagram of the seat cover structure with lining plate according to this utility model. The following is a combined view... Figure 1 , Figure 5 and Figure 6 The present invention describes a seat with a liner.

[0049] like Figure 1 , Figure 5 and Figure 6As shown, the seat 11 with a liner of this utility model includes a cover structure corresponding to the liner 13. The cover structure includes a first cut piece 21, an inner pocket fabric 22, and a support piece 23. The first cut piece 21 is covered on the back of the seat 11, and the inner pocket fabric 22 is disposed on the inner surface of the first cut piece 21. The inner pocket fabric 22 is disposed corresponding to the liner 13. The right side portion 221 and the left side portion 222 of the inner pocket fabric 22 are connected to the corresponding side portion of the first cut piece 21. The support piece 23 is connected to the inner pocket fabric 22 and is sandwiched between the inner pocket fabric 22 and the first cut piece 21. The liner 13 is sandwiched between the inner pocket fabric 22 and the support piece 23. The support piece 23 is used to support the liner 13.

[0050] Combination Figures 7 to 10 As shown, the inner pocket fabric 22 is disposed on the inner surface 211 of the first cut piece 21, forming a space for placing the liner 13 between the inner pocket fabric 22 and the inner surface 211 of the first cut piece 21. The right side portion 221 and the left side portion 222 of the inner pocket fabric 22 are correspondingly connected to the sides of the first cut piece 21. An opening is formed between the top 224 and the bottom 223 of the inner pocket fabric 22 and the first cut piece 21, allowing the liner 13 to be inserted between the inner pocket fabric 22 and the first cut piece 21 through the opening. When setting the liner 13, the liner 13 is placed from the bottom 223 of the inner pocket fabric 22 along... Figure 10 Insert the liner 13 between the inner pocket fabric 22 and the first cut piece 21 in the direction shown in F1, so that the bottom of the liner 13 passes over the support piece 23. Then insert the bottom of the liner 13 downwards between the support piece 23 and the inner pocket fabric 22 in the direction shown in F2, and use the support piece 23 to support the bottom of the liner 13. This completes the installation of the liner 13.

[0051] In one specific embodiment of this utility model, such as Figure 5 As shown, an operating opening is formed at the bottom of the inner bag fabric 22, connecting the space between the support piece 23 and the inner bag fabric 22.

[0052] Combination Figure 12 As shown, when installing the liner 13, if the installation position of the liner 13 is biased to one side, for example... Figure 12 The liner 13 shown is biased to the left. At this time, the liner 13 needs to be moved to the right along the direction shown in F4. After the operation port is set, the operator's fingers can be inserted upward along the direction shown in F3 between the inner bag fabric 22 and the support piece 23. Then, the operator can use their fingers to move the bottom of the liner 13 so that the liner 13 can be set as centrally as possible in the horizontal direction.

[0053] In a preferred embodiment, such as Figures 5 to 8As shown, the operating openings are notches 225 located on the left and right sides of the bottom of the inner pocket fabric 22. These notches 225 are located at the junction of the left side portion 221 and the bottom portion 223 of the inner pocket fabric 22, and at the junction of the right side portion 222 and the bottom portion 223 of the inner pocket fabric 22. The outer contour of the notch 225 is square, but it is not limited to this; the notch 225 can also be other shapes, such as arcs. The notches 225 can be formed by cutting off portions of the bottom left and right sides of the inner pocket fabric 22, for example... Figure 6 The square notch 225 shown can be formed by cutting off a square section from the bottom left and right sides of the bag fabric 22.

[0054] When notches 225 are provided at the two corners of the bottom 223 of the inner pocket fabric 22, the seam can be sewn to the edge corresponding to the notch 225 when sewing the inner pocket fabric 22 to the support piece 23 and the inner pocket fabric 22 to the first cut piece 21.

[0055] In another preferred embodiment, such as Figure 13 As shown, the operating opening is formed on the side and / or bottom of the inner bag fabric 22 where the support piece 23 is not connected.

[0056] When the sides and bottom of the support piece 23 are connected to the inner pocket fabric 22 by stitches, the stitches on the sides are spaced a distance from the bottom of the inner pocket fabric 22, and the stitches on the bottom are spaced a distance from the corresponding side (left side 222 or right side 221) of the inner pocket fabric 22. These distances on the sides and bottom create an operating opening, allowing the operator's fingers to easily reach between the inner pocket fabric 22 and the support piece 23. Alternatively, an operating opening can be formed in the middle of the bottom of the inner pocket fabric 22, allowing the operator to easily reach in and shape the lining plate 13.

[0057] When one of the support pieces 23 is formed on the side or bottom of the inner pocket fabric 22, such as Figure 15 and Figure 16 In the embodiment shown, when the bottom or side of the support piece 23 is connected to the inner bag fabric 22 by stitching, a distance is left between the bottom stitch and the corresponding side to form an operating opening.

[0064] like Figure 16As shown, the protruding part 226 is provided on the bottom 223 of the inner bag fabric 22. When connecting the support piece 23 and the inner bag fabric 22, the protruding part 226 can be folded along the third fold line A3, and then the side of the protruding part 226 can be connected to the corresponding side of the inner bag fabric 22. It can be connected by a sewing thread, which can be sewn to the bottom of the inner bag fabric 22 (when no operating opening is provided). The sewing thread can also leave a distance between it and the bottom of the inner bag fabric 22 to form an operating opening.

[0065] In the third embodiment, as Figure 17 As shown, the outer contour of the support piece 23 is rectangular. The rectangular support piece 23 is located at the bottom 223 of the inner bag fabric 22. The lateral dimension of the rectangular support piece 23 is consistent with the lateral dimension of the inner bag fabric 22.

[0066] In a preferred embodiment, such as Figure 18 As shown, the side of the rectangular support piece 23 is connected to the corresponding side of the inner pocket fabric 22, and the bottom of the support piece 23 is connected to the bottom of the inner pocket fabric 22. This connection can be achieved through stitching, for example, by using a first stitch 241 to connect the side of the rectangular support piece 23 to the corresponding side of the inner pocket fabric 22, and by using a second stitch 242 to connect the bottom of the rectangular support piece 23 to the corresponding bottom of the inner pocket fabric 22. Operating openings can be optionally provided on both sides of the bottom of the inner pocket fabric 22 as needed.

[0067] In another preferred embodiment, such as Figure 19 As shown, the rectangular support piece 23 is a protrusion 226 formed at the bottom of the inner pocket fabric 22. The protrusion 226 is folded along the first fold line A1, and then the side of the protrusion 226 is connected to the corresponding side of the inner pocket fabric 22. It can be connected by sewing. When setting the sewing, it is also possible to choose whether to set an operating port as needed.

[0068] In the fourth embodiment, as Figure 20 As shown, the outer contour of the support piece 23 is square, and the square support piece 23 is located on the left and right sides of the bottom 223 of the inner pocket fabric 22. The square support piece 23 can be a piece independent of the inner pocket fabric 22, and then the sides and bottom are connected to the inner pocket fabric 22 by stitches. Alternatively, the sides or bottom can be protrusions formed on the inner pocket fabric 22, folded along the fold line and then connected to the corresponding bottom or side.
