Description

Technical Field

[0001] This utility model belongs to the technical field of furniture, and specifically relates to a seating furniture. Background Technology

[0002] As seating functions become increasingly sophisticated, some chairs now allow for different postures, such as switching between sitting, reclining, and lying positions. These chairs typically have built-in adjustable seat supports that tilt the backrest to a reclining position. However, in some technologies, when switching from a sitting or reclining position to a reclining position, the backrest swings relative to the seat frame. As the backrest tilts backward, it can interfere with and collide with the armrests. Specifically, as the backrest swings backward, the armrests press against the backrest's support structure, hindering further backward movement and causing abnormal situations when switching to a reclining position.

[0044] Reference Figures 1 to 8 The following are some embodiments of the seating of this utility model.

[0045] like Figures 1 to 3As shown, the seat of this utility model embodiment includes a seat frame 100, armrests 200, and backrest 300. The armrests 200 are disposed on the seat frame 100. The backrest 300 includes a main body 310 and a backrest 320. The backrest 320 is slidably connected to the main body 310, and the backrest 320 and the main body 310 are arranged side by side. The main body 310 is mounted on the seat frame 100, and the backrest 320 is correspondingly disposed with respect to the armrests 200. The backrest 300 has an inclined position and a reclining position. When the backrest 300 changes from the inclined position to the reclining position, the backrest 300 flips relative to the seat frame 100 toward the rear of the seat. The squeezing force applied by the armrests 200 to the backrest 320 causes the backrest 320 to slide on the main body 310 to avoid the armrests 200.

[0046] The backrest 320 and the main body 310 are arranged side by side. The backrest 320 can increase the support area of ​​the backrest 300 to provide additional lateral support for the human back. When the seat changes from a sitting or reclining position to a lying position, the backrest 300 changes from an inclined position to a reclining position. The backrest 300 flips relative to the seat frame 100 toward the rear of the seat, forcing the backrest 320 to approach the armrest 200 and squeeze it. Since the backrest 320 is slidably disposed on the main body 310, the squeezing force exerted by the armrest 200 on the backrest 320 causes the backrest 320 to slide on the main body 310 to avoid the armrest 200, thus preventing the armrest 200 and the backrest 320 from interfering with each other and preventing the seat from being unable to change positions.

[0047] The backrest 320 and the main body 310 are arranged side by side. The backrest 320 can provide additional lateral support and a sense of enclosure, making it easy to support the arms or shoulders of the body when leaning back or lying on the side. The backrest 320 can increase the support area of ​​the backrest 300 and prevent cushions, blankets or small objects from slipping off the side of the seat. When the seat is placed against the wall, the backrest 320 can fit into the corner of the wall perfectly, avoiding gaps between the backrest 300 and the corner of the wall, making better use of space and reducing dead corners for cleaning. The backrest 300 of this utility model embodiment includes the main body 310 and the backrest 320. The backrest 320 moves relative to the main body 310, so that the backrest 320 avoids the armrest 200 during the movement of the backrest 300. While expanding the support area of ​​the backrest 300, it can also prevent the backrest 300 from interfering with the armrest 200 during the movement, thus preventing the seat from being unable to change positions.

[0048] In this embodiment, the seating is a sofa, and a cushion can be provided on the seat frame 100. The width of the main body 310 of the backrest 300 is approximately the same as the width of the seat frame 100. When the user sits upright on the seat frame 100, the main body 310 provides the main support for the user's back. During the process of the backrest 300 changing from an inclined position to a reclining position, the main body 310 will not interfere with other components such as the armrest 200. The backrest lugs 320 are arranged side by side with the main body 310 to expand the support area of ​​the backrest 300. The backrest lugs 320 are slidably connected to the main body 310. During the process of the backrest 300 changing from an inclined position to a reclining position, the backrest lugs 320 and the main body 310 are pressed together. Using the pressing force of the armrest 200, the backrest lugs 320 slide relative to the main body 310 to avoid the armrest 200 and prevent interference between the armrest 200 and the backrest. The seating has sitting posture, sitting-lying posture, and reclining posture; such as Figure 2 As shown, in a seated position, the backrest 300 is in a vertical position, and the user sits on the seat frame 100. The backrest 300 provides support for the user's lower back or back, and at this time, the angle between the backrest 300 and the seat frame 100 is minimal; as Figure 3 As shown, in a sitting or reclining position, the backrest 300 is in an inclined position, and the user leans against the backrest 300; Figure 4 As shown, in the reclining position, the backrest 300 is in a reclined position, allowing the user to rest on the seat.

[0049] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, one of the main body 310 and the backrest 320 is provided with a slide rail 400, and the other is provided with a slider 500. The slider 500 is slidably disposed on the slide rail 400. Through the cooperation of the slider 500 and the slide rail 400, the backrest 320 is slidably connected to the main body 310. The slide rail 400 is arranged along the length direction of the backrest 300. The slide rail 400 can guide the sliding path of the backrest 320, so that the backrest 320 moves in the length direction of the backrest 300, and avoids the backrest 320 and the main body 310 from being misaligned in the thickness direction of the backrest 300. When the backrest 300 moves to the reclining position, the main body 310 and the backrest 320 still remain in a side-by-side state so that the user can lie down.

[0050] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the seat also includes a reset member 600, which is connected to the main body 310 and the backrest 320; when the backrest 300 changes from a reclining position to an inclined position, the reset member 600 provides an elastic force to the backrest 320, causing the backrest 320 to abut against the armrest 200.

[0051] Understandably, the elastic force of the reset component 600 ensures that the backrest 300 remains in contact with the armrest 200 during position adjustment, preventing gaps between the backrest 300 and the armrest 200 that could pinch the user. During the transition from a reclining to a lying position, the pressure from the armrest 200 causes the backrest ear 320 to slide relative to the main body 310, at which point the reset component 600 compresses and stores energy. During the transition from a reclining to a tilted position, the elastic force of the reset component 600 gradually resets the backrest ear 320, preventing a sudden reset that could injure the user. Furthermore, the backrest ear 320's contact with the armrest 200 provides support to the backrest 300, distributing pressure and preventing deformation after prolonged use.

[0052] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, a slider 500 is provided on the side of the main body 310 facing the back ear portion 320, and a slide rail 400 is provided on the side of the back ear portion 320 facing the main body 310. The slider 500 is slidably disposed on the slide rail 400. One end of the reset member 600 is connected to the back ear portion 320, and the other end is connected to the slider 500. When the backrest 300 changes from an inclined position to a reclining position, the backrest 300 tilts back, and the back ear portion 320 and the armrest 200 are squeezed together. The squeezing force of the armrest 200 pushes the back ear portion 320 to move along the length direction of the backrest 300. At this time, the slider 500 slides on the slide rail 400, and the reset member 600 stretches and stores energy. When the backrest 300 changes from a reclining position to an inclined position, the reset member 600 releases its elastic potential energy. The elastic force of the reset member 600 drives the slider 500 to slide on the slide rail 400, so that the backrest 300 is reset. Compared to the main body 310, the back ear part 320 is smaller in size, and the main body 310 is complex to install and difficult to disassemble. By setting the slide rail 400 on the back ear part 320, setting one end of the reset part 600 on the slider 500, and then installing the slider 500 on the main body 310, the installation process can be simplified. During installation, the slide rail 400, slider 500 and connecting parts can be directly installed on the back ear part 320, reducing the installation difficulty and improving the assembly efficiency of the seat.

[0053] like Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, a mounting groove 321 is provided on the side of the backrest 320 facing the main body 310. The reset member 600 and the slide rail 400 are disposed in the mounting groove 321. The mounting groove 321 can quickly position the installation position of the slide rail 400, improving installation efficiency. The mounting groove 321 accommodates the reset member 600 and the slide rail 400, preventing the reset member 600 and the slide rail 400 from being exposed, and preventing external components from hindering the normal operation of the reset member 600 and the slide rail 400. This arrangement can minimize the distance between the backrest 320 and the main body 310, improve the compactness of the backrest 300, and thus improve the comfort of the backrest 300.

[0054] like Figures 5 to 7 As shown, in some embodiments, the reset member 600 includes a spring body 610 and a first hanging part 620 and a second hanging part 630 connected to the end of the spring body 610; a first fixing member 710 is provided on the side wall of the mounting groove 321, and a second fixing member 720 is provided on the slider 500; the first hanging part 620 is hung on the first fixing member 710, thereby completing the connection between the reset member 600 and the back ear part 320; the second hanging part 630 is hung on the second fixing member 720, thereby completing the connection between the reset member 600 and the slider 500. Both the first hanging part 620 and the second hanging part 630 are hooks, and both the first fixing member 710 and the second fixing member 720 are provided with hanging holes, with the hooks hanging in the corresponding hanging holes; the first fixing member 710 can be fixed to the mounting groove 321 by means of threaded connection, and the second fixing member 720 can be fixed to the slider 500 by means of threaded connection; the spring body 610, the first hanging part 620 and the second hanging part 630 are integrally formed, which is convenient for processing; specifically, both the first fixing member 710 and the second fixing member 720 are screws with holes.

[0055] like Figures 5 to 8 As shown, in some embodiments, the seat further includes a first locking member 730 and a second locking member 740. The first locking member 730 is fixed to the slider 500, and the second locking member 740 is fixed to the main body 310. The first locking member 730 has a slot 731, and the second locking member 740 is inserted into the slot 731 to fix the slider 500 and the main body 310. The second locking member 740 is inserted into the slot 731, which is simple to operate and does not require additional tools, allowing for quick assembly of the slider 500 and the main body 310. It should be noted that the second locking member 740 and the slot 731 are interference fits. The first locking member 730 is fixed to the slider 500 by screws, and the second locking member is fixed to the main body 310 by screws.

[0056] like Figures 5 to 8As shown, in some embodiments, the first snap-fit ​​part 730 is a sheet metal part, which is bent to form a slot 731. The slot 731 can be processed on the first snap-fit ​​part 730 through a bending process. The slot 731 formed by bending has stronger bending resistance, can withstand greater loads, and reduces the risk of local breakage. In addition, the slot can be processed in one step through the bending process, reducing processing steps and increasing material utilization.

[0057] In some embodiments, a limiting protrusion is provided on the inner side of the slot 731 to limit the displacement of the second locking member; during installation, the second locking member 740 is inserted into the slot 731 until the second locking member 740 abuts against the limiting protrusion to prevent the second locking member 740 from sliding out of the slot 731.

[0058] In some embodiments, there are two armrests 200, which provide support on both sides of the seat and improve the user experience; there are two backrests 320, which are positioned relative to the main body 310; the backrests 320 and the armrests 200 are positioned one-to-one; the two backrests 320 provide support on both sides of the user's body, preventing the body from sliding off the side when sitting or lying down, making it suitable for users to lean against for rest or a short nap.

[0059] like Figure 5 As shown, in some embodiments, the upper surface of the armrest 200 is arc-shaped, and the backrest 320 has an arc-shaped abutment surface 322 on the side facing the armrest 200. The abutment surface 322 is used to fit against the upper surface of the armrest 200. The arc shape of the upper surface of the armrest 200 and the arc shape of the abutment surface 322 can increase the contact area between the armrest 200 and the backrest 320 and reduce stress concentration. In addition, the arc shape allows the armrest 200 and the backrest 320 to fit completely, reducing the gap between the armrest 200 and the backrest 300 and preventing abnormal noises caused by friction and vibration.

[0060] In some embodiments, the seating also includes an extension mechanism, which connects the seat frame 100 and the main body 310 and is used to drive the backrest 300 to switch between an inclined position and a reclining position. By driving the backrest 300 to switch between an inclined position and a reclining position through the extension mechanism, the seating can be freely switched between sitting and reclining postures, thereby improving space utilization. The structure of the extension mechanism is prior art, and the specific structure of the extension mechanism can be referred to a sofa extension device for preventing forward tipping disclosed in Chinese Patent Publication No. CN113842000B. This utility model embodiment does not make any special limitation on this.

[0061] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
