[0031] Reference Figures 1 to 4An outer casing component is applied to a backrest 100, including an outer cover 200, a lower connecting strip 400, and an upper connecting strip 300. The outer cover 200 is located on the outer surface of the backrest 100, and a fixing layer 210 is provided on the outer cover 200. One end of the fixing layer 210 is provided with a perforation. In practical applications, the outer cover 200 can be made of fabric. After folding the top edge of the outer cover 200 backwards, the fixing layer 210 of the outer cover 200 is formed in the folded part. Alternatively, it can be directly... A lining-lined interlayer is formed on the outer cover 200 to form the aforementioned fixed interlayer 210; a lower connecting strip 400 is disposed at the bottom of the outer cover 200, and the bottom of the outer cover 200 is connected to the bottom of the backrest 100 through the lower connecting strip 400; an upper connecting strip 300 passes through the perforation and enters the fixed interlayer 210, and the fixed interlayer 210 is connected to the backrest 100 through the upper connecting strip 300, with the upper connecting strip 300 located above the lower connecting strip 400.

[0032] As described above, when assembling the backrest 100, the upper connecting strip 300 is passed through the perforation on the outside of the outer cover 200 and enters the fixing layer 210 at the top of the outer cover 200. The upper connecting strip 300 is stored within the fixing layer 210, enabling quick assembly of the upper connecting strip 300 and the outer cover 200 and preventing the upper connecting strip 300 from being exposed. At this time, the upper connecting strip 300 provides support for the outer cover 200, keeping it unfolded. The lower connecting strip 400 is connected to the bottom of the outer cover 200, providing support and unfolding at the bottom position of the outer cover 200. When the cover 200 is installed onto the backrest 100, the cover 200 can be quickly tensioned via the upper connecting strip 300 and the lower connecting strip 400. Then, the upper connecting strip 300 and the lower connecting strip 400 can be connected to the backrest 100, enabling quick assembly and disassembly of the cover 200 and the backrest 100. This improves the convenience of disassembling, maintaining, and replacing the cover 200. In actual production, the upper connecting strip 300 can also be connected to different positions on the backrest 100 above the lower connecting strip 400 according to different needs, forming different shapes and improving the overall production flexibility.

[0033] There are several ways to install the upper connecting strip 300 onto the backrest 100, such as... Figures 1 to 3As shown in Embodiment 1, the cover 200 is located on the front of the backrest 100. The portion of the cover 200 corresponding to the fixing interlayer 210 wraps around the top side of the backrest 100 and bends towards the back of the backrest 100. The portion of the cover 200 corresponding to the fixing interlayer 210 is tightened to the back of the backrest 100 by the upper connecting strip 300. When the upper connecting strip 300 is tightened on the back of the backrest 100, it is not easy for the upper connecting strip 300 to fold upward under the pulling force of the cover 200, thus securing it to the back of the backrest 100. The lower connecting strip 400 is connected to the bottom of the backrest 100. At this time, the cover 200 is tightened both vertically and horizontally, covering the front of the backrest 100 and forming a continuous appearance surface on the front of the backrest 100, improving the overall appearance and user comfort.

[0034] After passing over the top side of the backrest 100, the upper connecting strip 300 can be positioned at different locations on the upper, middle, and lower sides of the backrest 100. In this embodiment, the fixing interlayer 210 and the upper connecting strip 300 are respectively located at the top of the backrest 100, and the fixing interlayer 210 and the upper connecting strip 300 extend along the outer edge of the top side of the backrest 100. At this time, both the upper connecting strip 300 and the fixing interlayer 210 are located on the back of the backrest 100, close to the outer edge of the top side of the backrest 100. Thus, the upper connecting strip 300 is fixed by connecting with the top side of the backrest 100, and has a large exposed area on the back of the backrest 100.

[0035] In the above embodiment, the upper connecting strip 300 may extend only along the top edge of the backrest 100. To further improve the stability of the upper connecting strip 300 when taut at the top of the backrest 100, such as... Figure 6 As shown, the upper connecting strip 300 includes an upper snap-fit ​​portion 310 and two side snap-fit ​​portions 320 connected to both sides of the upper snap-fit ​​portion 310. The upper snap-fit ​​portion 310 is connected to the top of the backrest 100, and the two side snap-fit ​​portions 320 are respectively connected to the two sides of the backrest 100. The upper snap-fit ​​portion 310 and the two side snap-fit ​​portions 320 connected to it can improve the overall unfolding effect of the cover 200. When snapped to the top of the backrest 100, the upper snap-fit ​​portion 310 abuts against the back side of the top of the backrest 100, while the two side snap-fit ​​portions 320 abut against the back side of the two sides of the backrest 100. This effectively improves the stability of the upper connecting strip 300 on the back side of the backrest 100 and effectively prevents the upper connecting strip 300 from being pulled and flipped to the front of the backrest 100.

[0036] After the outer cover 200 is aligned with the upper connecting strip 300 against the back of the backrest 100, to further improve the stability of the engagement, such as... Figure 4As shown, in this embodiment, the backrest 100 has a raised anti-slip portion 110 on its back surface. The upper connecting strip 300 has an anti-slip groove 330 corresponding to the anti-slip portion 110, and the shape of the anti-slip groove 330 is adapted to the shape of the anti-slip portion 110. The anti-slip portion 110 and the anti-slip groove 330 work together to prevent the upper connecting strip 300 from moving upwards relative to the backrest 100, thereby further improving the stability of the upper connecting strip 300 at the top of the backrest 100.

[0037] In a second embodiment where the upper connecting strip 300 is installed on the backrest 100, the outer cover 200 is connected to the left and right ends of the fixed interlayer 210 at the left and right sides of the front of the backrest 100. In this case, the fixed interlayer 210 and the upper connecting strip 300 extend further downwards after bending at the back of the backrest 100. The outer cover 200 has connection points at the left and right ends of the fixed interlayer 210 and at the left and right sides of the front of the backrest 100, forming a cover that encloses the top of the backrest 100. In use, depending on the position of the fixed interlayer 210 and the upper connecting strip 300 extending downwards at the back of the backrest 100, it can create designs that partially or fully cover the back of the backrest 100.

[0038] There are several ways to connect the lower connecting strip 400 to the bottom side of the backrest 100. In this embodiment, the lower connecting strip 400 is snapped onto the bottom side of the backrest 100. The lower connecting strip 400 is fixed to the bottom side of the backrest 100 by snapping, improving the ease of assembly and disassembly. Figure 5 As shown, in practical applications, a slot can be provided on the bottom side of the backrest 100, and the lower connecting strip 400 is connected to the slot. During assembly, the bottom of the outer cover 200 is folded upwards, so that the lower connecting strip 400 is inserted into the slot on the bottom side of the backrest 100, thereby positioning the bottom of the outer cover 200. This securely attaches the lower connecting strip 400 to the bottom side of the backrest 100 and hides the structure of the lower connecting strip 400 and the slot, improving the overall appearance.

[0039] The lower connecting strip 400 can be connected to the bottom of the outer jacket 200 during assembly. However, in this embodiment, the lower connecting strip 400 is directly connected to the outer jacket 200 during production, and the lower connecting strip 400 is integrally connected to the bottom of the outer jacket 200. During assembly, this saves the step of assembling the lower connecting strip 400 and the outer jacket 200 together, improving overall assembly efficiency. There are various ways to integrally connect the lower connecting strip 400 and the outer jacket 200, such as by sewing, ultrasonic welding, adhesive, or mold heating and welding.

[0040] In some embodiments, the backrest 100 is provided with a plurality of ventilation holes 120, the cover 200 covers the front of the backrest 100, and the plurality of ventilation holes 120 are exposed on the back of the backrest 100. The presence of multiple ventilation holes 120 reduces the weight of the backrest 100 and facilitates ventilation of the cover 200, further improving user comfort.

[0041] In a third embodiment where the upper connecting strip 300 is installed on the backrest 100, the upper connecting strip 300 has a slot near the outer edge of the backrest 100. The outer edge of the backrest 100 abuts against the outer cover 200 and is inserted into the slot. During assembly, the top side of the backrest 100 is inserted into the slot of the upper connecting strip 300, thereby securing the upper connecting strip 300 to the top side of the backrest 100. Combined with the lower connecting strip securing the backrest 100, this allows the outer cover 200 to be tightened and positioned on the front or back of the backrest 100.

[0042] To facilitate the connection and fixation of the backrest 100, in this embodiment, connecting arms 130 are respectively provided on both sides of the bottom of the backrest 100. When assembling the seat, the connecting arms 130 on both sides of the bottom of the backrest 100 can be connected to the seat frame of the seat, thereby improving the firm connection and fixation of the backrest 100.

[0043] An office chair includes a seat frame, a backrest 100, and the aforementioned outer casing components, wherein the backrest 100 is disposed on the seat frame.

[0044] In this office chair, the backrest 100 is mounted on the seat frame. The backrest 100 allows for quick assembly and disassembly of the cover 200 and the backrest 100. When the cover 200 is installed onto the backrest 100, it can be quickly tensioned via the upper connecting strip 300 and the lower connecting strip 400. Then, the upper connecting strip 300 and the lower connecting strip 400 are connected to the backrest 100, enabling quick assembly and disassembly of the cover 200 and improving the convenience of disassembly, maintenance, and replacement. In actual production, the upper connecting strip 300 can be connected to different positions on the backrest 100 above the lower connecting strip 400 according to different needs, forming different shapes and improving the overall production flexibility.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
