Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically to a backrest with replaceable cushions. Background Technology

[0002] Chairs are essential seating in daily life, typically composed of a seat, backrest, and legs. The backrest is a crucial component for supporting the user's back. As users increasingly demand greater seating comfort, existing backrests often feature multiple cushions on the front, each supporting the head, neck, back, and lower back, providing a softer and more comfortable seating experience. Furthermore, the materials and functions of these cushions may vary. For example, cushions supporting the neck and shoulders might be made of soft foam, those supporting the back might be made of breathable mesh, and those supporting the lower back might include massage pads. By using different cushions, more functions are provided, further enhancing the seating experience.

[0003] However, existing backrest cushions on the market are usually fixed directly to the backrest, meaning they cannot be removed. This not only makes it inconvenient to wash and replace the cushions, but also prevents users from adjusting them to their individual needs. For example, when a user experiences neck and shoulder pain, they cannot move the lumbar massage cushion to the neck and shoulder area. This results in a lack of practicality for the backrest. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a backrest with replaceable cushions, in which several cushion units are detachably connected to the first mounting part and the second mounting part, making it easy to remove, replace and clean the cushion units; in addition, users can select cushion units of suitable materials or functions on the first mounting part and the second mounting part according to their own needs, which is more functional; and the cushion units on the first mounting part and the second mounting part can be freely interchanged, making the use and replacement of the cushion units more convenient and practical.

[0005] The effect of this utility model is achieved as follows:

[0006] This application provides a backrest with replaceable cushions, including a backrest body and a cushion assembly. The front end face of the backrest body has a mounting area for mounting the cushion assembly. The mounting area includes a first mounting part on the upper side and a second mounting part on the lower side. The cushion assembly includes multiple cushion units with different materials or functions. Several cushion units are detachably connected to the first mounting part and the second mounting part, and the cushion units on the first mounting part and the second mounting part can be freely interchanged.

[0007] Furthermore, the cushion unit and the mounting area are detachably connected via an adhesive structure. This structure includes a male Velcro strap on the back of the cushion unit and a female Velcro strap on the mounting area. The male and female Velcro straps adhere together to secure the cushion unit to the mounting area. This not only simplifies the installation and removal of the cushion unit but also allows the male Velcro straps on different cushion units to adhere to the same female Velcro strap, making it even easier to replace or swap the cushion units.

[0008] Furthermore, the cushion unit includes a first cushion unit and a second cushion unit. The first cushion unit is equipped with a massage device configured to massage the area supported by the first cushion unit. The second cushion unit is made of a flexible material. The first and second cushion units have different materials and functions, which makes the cushion unit provide a wider range of functions. Moreover, the same cushion unit can be installed on both the first and second mounting parts, making it highly practical.

[0009] Furthermore, a third backrest unit is fixed to the middle of the front end face of the backrest body, and the front end face of the backrest body is divided into a first mounting part and a second mounting part that are opposite each other. The third backrest unit not only provides a more comfortable support experience for the user's back, but also the backrest units installed in the first and second mounting parts abut against the third backrest unit, making installation and positioning more convenient, and making the connection between the backrest unit and the backrest body stronger and more stable.

[0010] Furthermore, the mounting area also includes a third mounting section located between the first and second mounting sections. The cushion unit includes a third cushion unit, which is detachably connected to the third mounting section. The third cushion unit can also be detachably connected to the backrest body, which not only facilitates disassembly and replacement, but also allows for the connection of various cushion units of different materials or functions to the third mounting section facing the user's back, resulting in richer functionality and better practicality.

[0011] Furthermore, several cushion units are similar in shape to each other. The shapes of cushion units of different materials or functions can be matched with the first mounting part and the second mounting part, making it easier to replace and swap the cushion units.

[0012] Furthermore, the backrest body includes a main support portion and secondary support portions symmetrically arranged on the left and right sides of the main support portion. Several side cushions are connected to each of the secondary support portions on both sides. The side cushions extend beyond the front end face of the main support portion in the front-back direction, and the recessed area formed between the side cushions and the front end face of the main support portion is configured as an installation area. This ensures that after the cushion unit is installed in the installation area, the two sides are supported by the side cushions, resulting in higher connection strength and better stability. Moreover, after the cushion unit is installed, the front end face of the cushion unit and the front end face of the side cushions are nearly flush, making the backrest more flat and aesthetically pleasing.

[0013] Furthermore, the secondary support sections are angled relative to the main support sections, and the distance between the two secondary support sections gradually decreases from front to back. This allows the side cushions on both sides to hold the user's left and right sides, providing a wider support surface and further enhancing comfort.

[0014] The replaceable cushion backrest provided in this application has several cushion units detachably connected to a first mounting part and a second mounting part. This allows the cushion units to be easily disassembled and their positions replaced according to usage needs, thus providing different functions to different parts of the backrest. Specifically, the cushion assembly includes multiple cushion units of different materials or functions. Users can select suitable cushion units on the first and second mounting parts according to their own needs, offering a wide range of functions. Furthermore, the cushion units on the first and second mounting parts can be freely interchanged, meaning that the types of cushion units that can be installed on the first and second mounting parts are the same, making the use and replacement of the cushion units simple and highly practical.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0023] Please refer to the attached document. Figure 1-5 This application provides a backrest with replaceable cushions, including a backrest body 1 and a cushion assembly. The front end face of the backrest body 1 has a mounting area 110 for mounting the cushion assembly. The mounting area 110 includes a first mounting part 111 located on the upper side and a second mounting part 112 located on the lower side. The cushion assembly includes multiple cushion units with different materials or functions. Several cushion units are detachably connected to the first mounting part 111 and the second mounting part 112, and the cushion units on the first mounting part 111 and the second mounting part 112 can be freely interchanged.

[0024] In this embodiment, several cushion units are detachably connected to the first mounting portion 111 and the second mounting portion 112, making it easy to disassemble, replace, and clean the cushion units. Furthermore, the cushion assembly includes multiple cushion units of different materials or functions, allowing users to select suitable cushion units from the first mounting portion 111 and the second mounting portion 112 according to their needs, offering a wide range of functions. Moreover, the cushion units on the first mounting portion 111 and the second mounting portion 112 can be freely interchanged, meaning that the types of cushion units that can be installed on the first mounting portion 111 and the second mounting portion 112 are also the same, making the use and replacement of the cushion units simple and highly practical.

[0025] Please refer to the attached document. Figure 3 In some embodiments of this application, the cushion unit and the mounting area 110 are detachably connected by an adhesive structure. The adhesive structure includes a male Velcro 3a disposed on the back side of the cushion unit and a female Velcro 3b disposed on the mounting area 110. The male Velcro 3a and the female Velcro 3b are adhesively engaged to fix the cushion unit to the mounting area 110. This not only simplifies the installation and removal of the cushion unit, but also allows the male Velcro 3a on different cushion units to be adhesively engaged with the same female Velcro 3b, making the replacement and swapping of the cushion units even easier.

[0026] Please refer to the attached document. Figure 1 and attached Figure 2 In some embodiments of this application, the cushion unit includes a first cushion unit 2a and a second cushion unit 2b. The first cushion unit 2a is provided with a massage device, which is configured to massage the part supported by the first cushion unit 2a. The second cushion unit 2b is made of a flexible material.

[0027] In this embodiment, the first cushion unit 2a and the second cushion unit 2b have different materials and functions, making the cushion units provide a wider range of functions. For example, different materials refer to different levels of softness; for instance, there are hard cushions or soft cushions filled with sponge. Different functions refer to different functions; one can simply provide support or have a massage function. (See attached...) Figure 1 As shown, when the first cushion unit 2a is disposed on the lower side of the second mounting portion 112 and the second cushion unit 2b is disposed on the upper side of the first mounting portion 111, the user's shoulders and neck can receive flexible support from the second cushion unit 2b, while the lower back can receive massage from the first cushion unit 2a. (See attached image) Figure 2 As shown, when a user experiences neck and shoulder pain, the first cushion unit 2a can be moved to the upper first mounting part 111, and the second cushion unit 2b can be moved to the lower second mounting part 112, making it very convenient to use.

[0028] Of course, the same cushion unit can also be installed on the first mounting part 111 and the second mounting part 112. For example, the first cushion unit 2a can be installed on both the first mounting part 111 and the second mounting part 112, thereby simultaneously massaging the user's shoulders, neck and waist, which is highly practical. In addition, the cushion unit can also have other different materials or functions, such as breathable mesh fabric, tough plastic material, memory foam with good resilience, etc.

[0029] Please refer to the attached document. Figure 3 In some embodiments of this application, a third cushion unit 2c is fixed to the middle of the front end face of the cushion body 1, and the front end face of the backrest body 1 is divided by the third cushion unit 2c into a first mounting part 111 and a second mounting part 112 that are opposite each other.

[0030] In this embodiment, the third cushion unit 2c in the middle of the backrest body 1 is used to divide the upper and lower sides into a first mounting part 111 and a second mounting part 112. This allows the third cushion unit 2c to not only provide a more comfortable support experience for the user's back, but also makes it easier to install and position the cushion units installed in the first mounting part 111 and the second mounting part 112 against the third cushion unit 2c. This also makes the connection between the cushion unit and the backrest body 1 stronger and more stable.

[0031] Please refer to the attached document. Figure 5 In some embodiments of this application, the mounting area 110 further includes a third mounting portion 113 located between the first mounting portion 111 and the second mounting portion 112, and the cushion unit includes a third cushion unit 2c, which is detachably connected to the third mounting portion 113.

[0032] In this embodiment, the third cushion unit 2c can also be detachably connected to the backrest body 1, which not only makes it easy to disassemble and replace, but also allows various cushion units of different materials or functions to be connected to the third mounting part 113 facing the user's back, making the functions richer and the practicality better.

[0033] Please refer to the attached document. Figure 5 In some embodiments of this application, several cushion units are similar in shape to each other. This allows the shapes of cushion units of different materials or functions to match the first mounting part 111 and the second mounting part 112, eliminating the need to design cushion units of different shapes for different areas on the mounting area 110, thus making the replacement and swapping of cushion units more convenient.

[0034] Please refer to the attached document. Figure 1 and attached Figure 4 In some embodiments of this application, the backrest body 1 includes a main support 1a and secondary support 1b symmetrically arranged on the left and right sides of the main support 1a. Each of the secondary support 1b on both sides is connected with a plurality of side cushions 4. The side cushions 4 extend beyond the front end face of the main support 1a in the front-back direction, and the recessed area formed between the side cushions 4 on both sides and the front end face of the main support 1a is configured as an installation area 110.

[0035] In this embodiment, the mounting area 110 is formed by the recessed area between the side cushions 4 on both sides and the front end face of the main support 1a. After the cushion unit is installed in the mounting area 110, the two sides are supported by the side cushions 4, resulting in higher connection strength and making it less likely to fall off the backrest body 1, thus improving stability. Furthermore, after the cushion unit is installed, the front end face of the cushion unit and the front end face of the side cushion 4 are nearly flush, making the backrest more flat and aesthetically pleasing.

[0036] Please refer to the attached document. Figure 1 and attached Figure 4 In some embodiments of this application, the secondary support portion 1b is inclined relative to the main support portion 1a, and the distance between the two secondary support portions 1b gradually shortens from front to back.

[0037] In this embodiment, by tilting the secondary support parts 1b on both sides, the side cushions 4 on both sides can hold the user's left and right sides, that is, the backrest can provide the user with a wrap-around support experience, with a wider support surface, further improving comfort.
