Description

Technical Field

[0001] This utility model relates to the field of automotive seats, specifically to a backrest back cover fixing structure, a backrest back, and a seat. Background Technology

[0002] With the continuous development of technology and the progress of social economy, people's requirements for products are no longer limited to the realization of basic functions. People have begun to pay attention to the appearance design of products. A product with a unique appearance can attract consumers' attention, thereby helping to increase product sales.

[0003] Car seats are no exception. The back of current car seat backs is relatively flat and lacks any features. The seat cover is set on the back of the seat back, and the part of the seat cover on the back of the seat back is relatively flat, without any undulations, so it cannot present a sense of three-dimensionality, texture, or aesthetics. It cannot give users or passengers a visual impact and cannot attract consumers' attention.

[0004] Therefore, setting a raised section with a certain height difference on the back of the car seat can enhance the three-dimensionality, texture, and aesthetics of the back of the car seat, presenting a unique shape that can attract consumers' attention.

[0005] However, when a raised section with a certain height difference is set on the back of the seat back, the seat cover will appear wrinkled, uneven, and not flat on the raised section, thus affecting the appearance of the seat cover. Utility Model Content

[0006] The present invention aims to provide a backrest cover fixing structure, a backrest, and a seat to solve the problem that the cover becomes wrinkled, uneven, and not flat after a protrusion with a certain height difference is set on the back of the car seat back.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a backrest cover fixing structure, including a protrusion on the back of the backrest, a gap on the back of the backrest, and a cover fixing wire in the gap, the gap being located on the outside of the protrusion and arranged along the direction of the protrusion.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a backrest back cover fixing structure is provided.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a seat, including a seat back and a seat cushion, wherein the seat back is provided with a backrest.

[0010] The principle and advantages of this patented solution are as follows: The protrusions create a raised surface with a certain height difference on the back of the seat back, enhancing its three-dimensionality, texture, and aesthetics, resulting in a unique design. The gaps allow the cover to be inserted into the back of the seat back. Once inserted, the cover is connected to the cover fixing wire via a connector, tautning it and providing support for the cover at the protrusions. This makes the cover at the raised surface of the seat back more flat and smooth, solving the problem of wrinkles, unevenness, and non-flatness caused by the raised surface on the back of the car seat back.

[0011] The gap is located on the outside of the protrusion and is set along the direction of the protrusion, so that the faceplate located on the protrusion can enter the gap well, smoothly and naturally, and the faceplate has a better supporting effect.

[0012] Preferably, as an improvement, the backrest includes a backrest body and a backrest body mounted on the backrest body, with a protrusion located on the backrest body and a gap located at least on the backrest body.

[0013] Preferably, as an improvement, the backrest body is provided with a mounting groove, the backrest body is installed in the mounting groove, and the gap is the gap between the backrest body and the backrest body.

[0014] The reason why there are no raised sections with a certain height difference on the back of the seat back in the existing technology is that the foam of the car seat back is molded as a whole, and a seat back with a raised section with a certain height difference cannot be directly molded, thus making it impossible to manufacture such a car seat back.

[0015] By using the solution of this patent, the inventors have abandoned the method of one-piece molding of the seat back. Instead, the backrest body and the main body of the backrest with the mounting groove are molded separately. Both are molded separately and then assembled together to form a raised backrest with a certain height difference. This solves the problem that the existing technology cannot manufacture a seat backrest with a certain height difference. The manufacturing of a seat backrest with a certain height difference is simple and convenient.

[0016] The backrest is installed in the mounting slot, and a gap is naturally formed between the inner wall of the mounting slot and the backrest. Therefore, the inventor uses the gap formed by the backrest installed in the mounting slot to allow the face cover to enter the gap between the backrest body and the backrest. It is then connected to the face cover by a connecting piece and a fixing wire, thereby achieving the support of the face cover located at the protrusion without the need to set an additional gap on the backrest body.

[0017] Preferably, as an improvement, the length of the gap is 340-360mm.

[0018] Preferably, as an improvement, the depth of the gap is 20-30mm.

[0019] Preferably, as an improvement, the protrusion is located at the top of the back body.

[0020] Preferably, as an improvement, the protrusion extends 9-12mm beyond the back of the main body of the backrest.

[0021] Preferably, as an improvement, a cover is provided on the back of the backrest, the cover is inserted into the gap, and a connector is connected to the part of the cover that is inserted into the gap, and the connector is connected to the cover fixing wire. Attached Figure Description

[0027] The following detailed description illustrates the specific implementation method:

[0028] The reference numerals in the accompanying drawings include: back body 1, backrest main body 2, mounting groove 3, first steel wire 4, second steel wire 5, locking block 6, first engaging part 7, second engaging part 8, locking groove 9, protrusion 10, face cover fixing wire 11, face cover 12, connector 13, gap 14.

[0029] Example 1

[0030] The basics are as follows: Figure 1 , Figure 2 and Figure 5 As shown.

[0031] This embodiment discloses a seat, including a seat back and a seat cushion, wherein the seat back is provided with a backrest. Figures 1-2 The main illustration shows the backrest of the seat.

[0032] The backrest in this embodiment includes a backrest body 2 and a backrest body 1 mounted on the backrest body 2. A backrest cover fixing structure is provided on the backrest cover. This backrest cover fixing structure includes a protrusion 10 on the backrest cover, a gap 14 on the backrest cover, and a cover fixing wire 11 located in the gap 14. The gap 14 is located outside the protrusion 10 and is arranged along the direction of the protrusion 10.

[0033] Specifically, combined Figure 2 As shown, in this embodiment, the backrest body 2 is provided with a mounting groove 3, and the backrest body 1 is installed in the mounting groove 3, combined with... Figure 1 As shown, gap 14 is the gap between the backrest body 2 and the backrest body 1. In this embodiment, gap 14 is located between the top of the mounting groove 3 and the top of the backrest body 1, and the length of gap 14 is 340-360mm. The depth of gap 14 is 20-30mm. In this embodiment, protrusion 10 is located at the top of the backrest body 1. The height of protrusion 10 from the back of the backrest body 2 is 9-12mm.

[0034] In this embodiment, the face cover fixing wire 11 is fixed at the top inner side wall of the mounting groove 3. The length of the face cover fixing wire 11 is the same as the length of the gap 14. The face cover fixing wire 11 is welded to the metal frame inside the backrest body 2, or the face cover fixing wire 11 is embedded in the backrest body 2.

[0035] Therefore, combined Figure 5 As shown, the backrest 1 is installed in the mounting groove 3. There is a gap 14 between the top of the mounting groove 3 and the top of the backrest 1. The face cover 12 provided on the backrest enters the gap 14. The face cover 12 can be just the face cover 12 on the backrest 1 entering the gap 14, or the face cover 12 on the backrest 1 and Figure 5 The face mask 12 on the right side of the backrest body 2 of the mid-back panel 1 all enters the gap 14. A connector 13 is connected to the part of the face mask 12 that enters the gap 14, and the connector 13 is connected to the face mask fixing wire 11. In this embodiment, the connector 13 is a hook, which is hung on the face mask fixing wire 11, thus connecting the connector 13 and the face mask fixing wire 11. In this embodiment, the connector 13 can be directly sewn together with the part of the face mask 12 that enters the gap 14, or a connecting strap can be sewn between the connector 13 and the part of the face mask 12 that enters the gap 14, with the strap serving as an intermediate connecting element.

[0036] Therefore, the backrest body 1 is installed in the mounting groove 3. The protrusion 10 on the backrest body 1 creates a raised area with a certain height difference on the back of the seat back, which enhances the three-dimensionality, texture, and aesthetics of the back of the car seat back, presenting a unique shape. At the same time, the gap 14 is used to allow the cover 12 provided on the back of the seat back to enter. After the cover 12 enters the gap 14, the cover 12 is connected to the cover fixing wire 11 through the connector 13, making the cover 12 taut. This provides support for the part of the cover 12 located at the protrusion 10, making the cover 12 at the raised area with a certain height difference on the back of the seat back more flat and smooth. This solves the problem of wrinkles, unevenness, and non-flatness of the cover 12 caused by the raised area with a certain height difference on the back of the car seat back.

[0037] Further specifying, in this embodiment, the shape of the mounting groove 3 is similar to an isosceles trapezoid, wherein the length of the lower base of the isosceles trapezoid is basically the same as the length of the gap, the length of the upper base is 280-300mm, and the length of the waist is 110-130mm. The depth of the mounting groove 3 is 20-30mm.

[0038] In this embodiment, the backrest body 1 is made of EPP material. The backrest body 2 is also made of foam material (after the backrest body 2 is formed, a skeleton will be installed inside the backrest body 2 to support it).

[0039] The reason why the backrest body 1 can be detachably installed on the back of the backrest body 2 in this embodiment is that the existing technology of integrally molding the seat back cannot form a raised structure with a height difference. Therefore, in this embodiment, the backrest body and the backrest body 2 with the mounting groove 3 are both molded separately, and then the two are assembled together to form a raised seat back with a certain height difference. This solves the problem that the existing technology cannot manufacture a seat back with a certain height difference due to the integral molding of the seat back.

[0040] In this embodiment, the detachable connection between the backrest body 1 and the backrest body 2 can be achieved by snap-fitting or by fixing with screws.

[0041] Of course, in other embodiments, the shape and size of the back body 1 can be changed according to actual needs, and the location and shape of the protrusion 10 can also be changed according to actual conditions. When the protrusion 10 is located at the bottom of the back body 1, the gap is the gap between the bottom edge of the mounting groove 3 (if present) and the bottom of the back body 1. When the protrusion 10 is located on the side of the back body, the gap is the gap between the side of the mounting groove 3 and the side of the back body 1.

[0042] Example 2

[0043] This embodiment further defines the scope of Embodiment 1. Combined with... Figure 2 As shown, in this embodiment, a backrest fixing wire is installed in the mounting groove 3. There are two backrest fixing wires: a first wire 4 and a second wire 5. The first wire 4 and the second wire 5 are located below the faceplate fixing wire 11, with the first wire 4 above the second wire 5. Both the first wire 4 and the second wire 5 are bent. The opening of the groove formed after bending the first wire 4 faces upwards, and the opening of the groove formed after bending the second wire 5 faces downwards. The first wire 4 and the second wire 5 can be welded and fixed to the metal frame inside the seat back, or they can be embedded in the backrest body 2.

[0044] Combination Figure 3 and Figure 4 As shown, in this embodiment, the inner side of the back body 1 is integrally fixed with multiple engaging parts, with at least two rows of engaging parts. In this embodiment, there are two rows of engaging parts, with two engaging parts in each row. The first row consists of first engaging parts 7, located near the top of the back body 1, and the second row consists of second engaging parts 8, located near the bottom of the back body 1. Both the first engaging parts 7 and the second engaging parts 8 are bent downwards, creating a slot 9 between the engaging parts and the inner side of the back body 1 for accommodating steel wires. Thus, the slots 9 on the first engaging parts 7 and the second engaging parts 8 are oriented in the same direction, both facing downwards, facilitating the installation of the back body 1 in the mounting groove 3 where all engaging parts are hung on the corresponding steel wires. The inner side of the back body 1 is integrally fixed with a locking block 6 for engaging into the groove formed by bending the first steel wire 4. The locking block 6 is located between the two first engaging parts 7.

[0045] Therefore, the back body 1 is installed in the mounting groove 3. The first steel wire 4 is engaged in the first engaging part 7 and the groove 9 on the inner side of the back body 1, with the first engaging part 7 hanging on the first steel wire 4. At the same time, the locking block 6 is located in the groove formed by the bending of the first steel wire 4. The second steel wire 5 is engaged in the second engaging part 8 and the groove 9 on the inner side of the back body 1, with the second engaging part 8 hanging on the second steel wire 5. Since the locking block 6 is located in the groove formed by the bending of the first steel wire 4, the first steel wire 4 can limit the locking block 6, thereby limiting the back body 1 and restricting its left and right movement. The first steel wire 4 and the second steel wire 5 are both located on the inner side of the back body 1, and the first steel wire 4 and the second steel wire 5 can strengthen the structure of the back body 1. At the same time, the first engaging part 7 and the second engaging part 8 are respectively hung on the first steel wire 4 or the second steel wire 5, making the back body 1 more stable and less likely to fall off in the mounting groove 3. The fixing method of the backrest body 1 and the backrest body 2 in this embodiment does not require the use of screws for fixing, which makes it easy to install and fix the backrest body 1 in the mounting groove 3.

[0046] Furthermore, in this embodiment, the ends of the first engaging portion 7 and the second engaging portion 8 are both bent towards the backrest body 1, forming an inverted buckle. Thus, the first steel wire 4 and the second steel wire 5 are engaged in their respective slots 9. The inverted buckle structure at the ends of the engaging portions prevents the backrest body 1 from moving upwards (in the upward direction of the seat) in the mounting groove 3, thus preventing the first steel wire 4 and the second steel wire 5 from disengaging from their respective slots 9. This makes the engagement of the first steel wire 4 and the second steel wire 5 on the first engaging portion 7 and the second engaging portion 8 more stable, and the backrest body 1 is less likely to move upwards and fall off.
