Description

Technical Field

[0001] This application relates to the field of cushion technology, specifically to a type of cushion. Background Technology

[0002] A cushion is an accessory designed specifically for sitting or sleeping furniture. Its main function is to adjust the sitting posture of the body and provide extra comfort and support. They are usually made of soft and durable fabric materials, and the internal filling is often made of fluffy sponge, down or memory foam to ensure optimal support and feel. Cushions are widely used on a variety of furniture such as sofas, beds, and chairs.

[0003] An existing patent (publication number: CN218009035U) discloses a backrest cushion, which includes a flexible lumbar support portion. A shaping member is provided on the back of the lumbar support portion, and the shaping member is horizontally arranged along the lumbar support portion. The shaping member has deformation capability, and the lumbar support portion deforms synchronously with the shaping member. This backrest cushion has the effect of shaping, allowing it to better support the lower back, thus improving comfort and usability.

[0004] The aforementioned cushions only provide lumbar support and do not consider the overall comfort of the user when sitting. Furthermore, they cannot be heated as needed, failing to provide a warm and comfortable environment for the user, and thus have room for improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a backrest cushion that meets the overall support needs when sitting, improving the comfort of the buttocks, waist, and back. It can also be heated as needed to provide a warm and comfortable environment and relieve physical fatigue. This solves the problems of existing backrest cushions that only provide lumbar support, do not consider the overall comfort of the user when sitting, and cannot be heated as needed to provide a warm and comfortable environment for the user.

[0006] To achieve the above objectives, this application provides the following technical solution: a cushion, including a cushion base layer, wherein a heating wire is provided inside the cushion base layer, and a lumbar cushion is fixedly connected to the outer surface of the cushion base layer. The cushion base layer is divided into a seat cushion part and a back cushion part with the lumbar cushion as the dividing line. Two blankets are fixedly connected to the outer surface of the seat cushion part, and the two blankets are symmetrically arranged on both sides of the seat cushion part.

[0007] The above solution addresses the issue that existing backrests only provide lumbar support without considering overall user comfort, and cannot be heated as needed, thus failing to provide a warm and comfortable environment. By incorporating a base layer with both a seat cushion and a backrest, and adding a lumbar support between them, the solution meets the user's overall support needs, significantly improving comfort for the hips, waist, and back. Furthermore, by installing heating wires within the base layer, heating can be provided as needed, creating a warm and comfortable environment, relieving fatigue, and enhancing the practicality of the backrest.

[0008] Furthermore, the base layer of the backrest is made of cotton fabric, and the interior of the lumbar cushion is made of memory foam.

[0009] Through the above solutions, the cotton fabric base layer of the cushion has good breathability and moisture absorption, which can keep the inside of the cushion dry and will not feel stuffy even after long-term use. The memory foam material can provide support according to the curves of the human body and effectively relieve lumbar pressure.

[0010] Furthermore, a long-pile fabric layer, which is made of wool, is fixedly connected to the outer surface of both the seat cushion and the backrest.

[0011] Through the above solution, the long-pile fabric layer of wool has good warmth retention and breathability, keeping you warm without feeling stuffy even in cold seasons, thus optimizing the overall comfort of the cushion during use.

[0012] Furthermore, the blanket is a plush blanket, and the plush material of the blanket is milk fleece.

[0013] Through the above methods, milk fleece is known for its softness, delicacy, and warmth. Covering a user with a milk fleece blanket provides warmth and extra comfort.

[0014] Furthermore, elastic bands are fixedly connected to both sides of the seat cushion and the backrest. On one side, the ends of the two elastic bands away from the backrest base are fixedly connected to male buckles, and on the other side, the ends of the two elastic bands away from the backrest base are fixedly connected to female buckles.

[0015] The above solution allows the male buckle on one side of the elastic band to be fastened to the female buckle on the other side, fixing the seat cushion to the chair seat and backrest. This secures the cushion, preventing it from easily slipping or falling off and affecting its use. The design of the elastic band, male buckle, and female buckle facilitates the installation, removal, and use of the cushion, providing convenience for the user.

[0016] Furthermore, the outer surface of the lumbar pad is provided with a recessed portion, which is centrally located.

[0017] The above design of the recessed part conforms to ergonomic principles, can better fit the waist curve, support the waist, and reduce waist fatigue.

[0018] Furthermore, the heating wire is made of zinc-copper alloy and is evenly distributed in a serpentine pattern.

[0019] Through the above solution, the zinc-copper heating wire has good conductivity and corrosion resistance, which can ensure the long-term stable operation of the heating wire. The serpentine and evenly distributed heating wire can ensure that the heat inside the cushion is evenly distributed, avoiding local overheating or underheating, providing a more comfortable heating experience, and ensuring the uniformity of the cushion's heating.

[0020] Furthermore, the lumbar cushion has a controller inside, which is electrically connected to an external smart mobile terminal. The lumbar cushion also has a battery inside and a power interface on its outer surface.

[0021] With the above solution, users can use smart devices such as mobile phones to control the opening and closing of the cushion, the heating time and heating temperature, etc., to achieve intelligent management and facilitate user use. The battery can store electrical energy, allowing users to use the cushion anytime and anywhere. It avoids the limitation of the cushion being restricted by the length of the power cord and can be connected to an external power source through the power interface, so that the cushion can also be used directly by an external power source.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This cushion, by featuring a base layer with a seat cushion and a backrest, and a lumbar support between the two, meets the overall support needs of users when sitting, improving the comfort of the buttocks, waist, and back. With heating wires inside the base layer, it can be heated as needed, providing a warm and comfortable environment, relieving fatigue, and enhancing the cushion's practicality. It solves the problems of existing cushions that do not consider overall user comfort when sitting and cannot be heated as needed, thus failing to provide a warm and comfortable environment.
