Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a corner cover fixing structure for automotive seats and an automotive seat. Background Technology

[0002] In car seats, some rotatable parts have right-angle transitions at their ends to prevent them from interfering with other parts during rotation. For example, the left and right sides of the lower end of the backrest (i.e., the bottom corners) have right-angle transitions to prevent the backrest from interfering with the plastic parts of the seat when it rotates.

[0003] The cover, which covers the outer side of the foam on a car seat, plays a decisive role in the seat's appearance, and its design is particularly important for right-angle corners. Currently, there are two main designs for corner covers: one uses a single piece of fabric for the corner structure, and the other adds vertical dividing lines to the fabric piece at the corner. During use, because the cover is not secured to the foam, the first design is prone to problems such as significant interference between the cover and the plastic parts, and fabric wrinkles. The second design is prone to problems such as excessive fabric exposure and rattling noises during adjustment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a corner cover fixing structure for car seats that is aesthetically pleasing, exquisite, has a good fit, and can solve the problem of abnormal noise, as well as a car seat.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] like Figures 1-2 As shown, this embodiment of a corner cover fixing structure for a car seat mainly includes: a frame 1, a foam component 2, a cover 3, and a fixing component 4. The frame 1 serves as a strength support for the car seat and can accommodate the installation of other components. The foam component 2 is mounted on the frame 1 and fixedly installed thereto. The foam component 2 effectively ensures the comfort of the car seat and has a corner portion 20, which is a right-angled or near-right-angled structure. The cover 3 covers the foam component 2. The surface cover 3 includes a main cut piece 31 and a connecting cut piece 32. The connecting cut piece 32 is connected to the inner surface of the main cut piece 31 and is close to the corner 20. The main cut piece 31 covers the outer surface of the foam 2. The fastener 4 fixes the connecting cut piece 32 to the frame 1. The connecting cut piece 32 is close to the corner 20. After being fixed to the frame 1 by the fastener 4, the cover 3 at the corner 20 can be suspended tightly on the frame 1, so that the cover 3 at the corner 20 fits the corner better.

[0039] In actual use, the cover 3 includes a main cut piece 31 and a connecting cut piece 32. At the corner 20 of the foam part 2, the main cut piece 31 covers its surface, and the connecting cut piece 32 is fixed to the frame 1 by the fastener 4. That is, the cover 3 at the corner 20 has an additional fixing layer, which can solve the problem of uneven exposure of auxiliary materials, ensure that the cover 3 fits well at the corner 20, improve aesthetics and delicacy, and avoid the problem of friction causing interference and abnormal noise when the corner 20 moves.

[0040] like Figure 2 and Figure 4 As shown, in this embodiment, the connecting piece 32 and the main piece 31 can be made of the same material. The connecting piece 32 is sewn onto the inner surface of the main piece 31. The main piece 31 and the connecting piece 32 are connected by sewing, which is simpler than other fixing methods and provides a better connection effect. Furthermore, a dividing line 310 is provided on the main piece 31 near the corner 20. This dividing line 310 is a horizontal dividing line. The stitching connecting the connecting piece 32 is sewn along the dividing line 310. In this way, no extra stitching is visible from the outside, ensuring a good aesthetic appearance.

[0041] Explanation is required, such as Figure 5 As shown, the corner portion 20 on the foaming component 2 in this embodiment is a right-angled structure or an approximately right-angled structure. The corner portion 20 has a main plane 201 and a right-angled surface 202 perpendicular to the main plane 201. The right-angled surface 202 can be a plane or a curved surface. The main plane 201 and the right-angled surface 202 are connected by a rounded transition.

[0042] For existing car seats, the cover 3 at the right-angled surface 202 of the corner portion 20 cannot fit well against the right-angled surface 202. When the right-angled surface 202 rotates relative to the corner portion 20, it is easy to rub against the surrounding fixed parts, generating noise and affecting the user experience. In this embodiment, a connecting piece 32 is added near the corner portion 20. The connecting piece 32 is fixed to the frame 1. The fixing of the connecting piece 32 can help fix the main piece 31, ensuring that the cover 3 can fit well against the right-angled surface 202. That is, the main piece 31 covers the corner portion 20 and abuts against the corner portion 20. The fit between the main piece 31 and the main plane 201 and the right-angled surface 202 of the corner portion 20 is good.

[0043] Combination Figures 2-4As shown, in this embodiment, the fastener 4 includes a first fixing part 41 and a second fixing part 42. In addition to the first fixing part 41 and the second fixing part 42, the fastener 4 also includes a connecting piece (not shown in the figure). The first fixing part 41 is located at one end of the connecting piece and protrudes from it; the second fixing part 42 is located at the other end of the connecting piece and protrudes from it. The protrusion direction of the second fixing part 42 is the same as that of the first fixing part 41. Ideally, the first fixing part 41 and the second fixing part 42 have the same structure and are symmetrically arranged. This ensures that the fastener 4 can fix the connecting piece 32 in both forward and reverse directions during assembly.

[0044] Furthermore, in this embodiment, the fastener 4 also has a guide head at the end of the first fixing part 41 and the second fixing part 42. The size of the guide head is smaller than the size of the main body of the first fixing part 41 and the second fixing part 42, so as to facilitate the accurate positioning of the corresponding fixing holes on the frame 1 when assembling the first fixing part 41 and the second fixing part 42.

[0045] Furthermore, in this embodiment, the fastener 4 is provided with multiple tensioning plates on the main body of the first fixing part 41 and the second fixing part 42. The structure is similar to that of an expansion screw, which makes it easier to insert the first fixing part 41 and the second fixing part 42 into the fixing hole, and makes it more difficult for the first fixing part 41 and the second fixing part 42 to come out of the corresponding fixing hole. Only when the user needs to remove them can a large disassembly force be applied outward to make the first fixing part 41 and the second fixing part 42 come out of the corresponding fixing hole, that is, to remove the fastener 4 from the frame 1.

[0046] The connecting piece 32 is provided with a first through hole 321 and a second through hole 322, and the skeleton 1 is provided with a first fixing hole 11 and a second fixing hole 12. The first through hole 321, the second through hole 322, the first fixing hole 11, and the second fixing hole 12 are all round holes, which are simpler to create compared to other shapes. The diameter of the first fixing hole 11 and the second fixing hole 12 is 5 mm, and the diameter of the first through hole 321 and the second through hole 322 is greater than or equal to 5 mm. The diameter of the main body of the first fixing part 41 and the second fixing part 42 is slightly greater than 5 mm, forming an interference fit when inserted into the two fixing holes.

[0047] The first fixing part 41 and the second fixing part 42 pass through the first through hole 321 and the second through hole 322, respectively, and are fixed in the first fixing hole 11 and the second fixing hole 12, respectively. That is, the first fixing part 41 passes through the first through hole 321 on the connecting piece 32 and is fixed in the first fixing hole 11 on the skeleton 1, and the second fixing part 42 passes through the second through hole 322 on the connecting piece 32 and is fixed in the second fixing hole 12 on the skeleton 1, ensuring the fixing effect between the connecting piece 32 and the skeleton 1 and preventing it from easily loosening.

[0048] Of course, the fastener 4 in this embodiment can also be provided with more fastening parts to ensure that the fastener 4 will fix the connected cut piece 32. From the perspective of assembly efficiency and fixing effect, setting two fasteners 4 not only ensures assembly efficiency and fixing effect, but also makes disassembly convenient.

[0049] Preferably, in this embodiment, the first fixing part 41 is detachably fixed in the first fixing hole 11, and the second fixing part 42 is detachably fixed in the second fixing hole 12. Both the first fixing part 41 and the second fixing part 42 are detachably fixed, which makes it convenient to remove the fixing member 4 from the frame 1.

[0050] The frame 1 has multiple first fixing holes 11 and second fixing holes 12. Since both first fixing holes 11 and second fixing holes 12 are 5 mm in diameter, they are essentially identical. The multiple 5 mm diameter holes on the frame 1 facilitate the insertion of the first fixing part 41 and the second fixing part 42. During assembly, the user can fix the first fixing part 41 and the second fixing part 42 into the corresponding fixing holes according to actual fixing requirements, ensuring a precise one-to-one correspondence. The user can also adjust the tightness of the connecting piece 32.

[0051] Specifically, when the corner cover 3 fixing structure of this embodiment is applied to a car seat, the car seat is equipped with the aforementioned corner cover 3 fixing structure. For example, the car seat includes a seat and a backrest that is rotatably mounted on the seat. Plastic parts are provided on both sides of the seat near the backrest, and a corner part 20 is provided on the backrest at the corresponding position. That is, the corner part 20 is equipped with the corner cover fixing structure of this embodiment.

[0052] In this solution, an additional fixing layer is added to the cover 3 at the corner, which can solve the problem of uneven exposure of auxiliary materials; it can also ensure the fit between the cover 3 and the main plane 201 and right angle plane 202 of the corner part 20, thereby improving the sense of refinement; it can also ensure that there is a gap between the cover 3 and the surrounding plastic parts during movement, thereby solving the problem of abnormal noise.
