Description

Technical Field

[0001] This utility model relates to the field of seat cushion technology, specifically to a breathable and shock-absorbing seat cushion. Background Technology

[0002] Currently, common seat cushions on the market are mainly divided into ordinary sponge cushions, memory foam cushions, gel cushions, and inflatable cushions. While these cushions provide cushioning and support to some extent, they still have the following technical problems: Insufficient breathability: Traditional cushions (such as sponge or memory foam) are dense in material, which can easily lead to heat and moisture accumulation after prolonged use, causing discomfort and even skin problems for the user's buttocks; although some cushions are designed with ventilation holes, they are mostly simple flat openings with limited air circulation and cannot form an effective three-dimensional ventilation channel. Limited shock absorption performance: Most cushions use homogeneous materials (such as sponge or gel of a single density), which can provide some cushioning, but cannot provide differentiated support for the pressure distribution of different parts of the body; for example, the ischial tuberosity area bears greater pressure and requires stronger support, while the sides of the thighs require softer cushioning, and traditional cushions cannot meet these needs simultaneously. Poor anti-slip stability: Many seat cushions use smooth materials (such as ordinary fabric or plastic) on the bottom, making them prone to sliding on the seat, affecting comfort and safety. Although some products add anti-slip particles or silicone dots, the anti-slip effect is limited and may affect the breathability of the cushion. Insufficient structural durability: Some seat cushions (such as inflatable or low-density sponge) are prone to collapsing and deforming after long-term pressure, resulting in decreased support performance and a shorter lifespan. Inconvenient cleaning and maintenance: Traditional seat cushions usually adopt an overall closed design with few or no ventilation holes, making them difficult to clean. Sweat and dust can easily seep into the interior, breeding bacteria and affecting hygiene. To address the above problems, some improvements have been made in existing technologies, such as: using mesh fabric to enhance breathability, but this may result in insufficient support; incorporating springs or honeycomb structures inside the cushion to improve elasticity, but these are complex and costly; using a gel layer to improve heat dissipation, but the gel material is heavy and prone to shifting. However, these solutions still fail to achieve a good balance between breathability, shock absorption, anti-slip properties, and durability.

[0003] Therefore, this utility model provides a breathable and shock-absorbing seat cushion, a novel seat cushion design that is simple in structure, reasonable in cost, and can simultaneously meet the requirements of comfort and functionality. The seat cushion of this utility model solves the problems of stuffiness, uneven support, and easy slippage of traditional seat cushions through the optimized design of three-dimensional breathability + zoned shock absorption + anti-slip and stable design. It is suitable for various scenarios such as office chairs, car seats, and wheelchairs, and has comprehensive advantages such as high comfort, long service life, and low cost, and has broad market application prospects. Utility Model Content

[0004] The purpose of this utility model is to provide a breathable and shock-absorbing seat cushion, so as to achieve a new seat cushion design that is simple in structure, reasonable in cost, and can simultaneously meet the requirements of comfort and functionality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A breathable and shock-absorbing seat cushion includes a top layer (1) and a bottom layer (2), wherein the top layer (1) is provided with an array of shock-absorbing protrusions (3).

[0007] Preferably, a through-hole (4) is formed between the shock-absorbing protrusions (3).

[0008] Preferably, the height of the shock-absorbing protrusion (3) varies in a gradient.

[0009] Preferably, the bottom layer is provided with anti-slip texture (5).

[0010] Preferably, the shock-absorbing protrusion (3) is made of silicone.

[0011] Preferably, the diameter of the vent (4) is 3-8 mm.

[0012] Preferably, the bottom layer (2) is a TPU waterproof layer.

[0013] Preferably, the surface layer (1) has an annular ventilation channel (6) on its side.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] 1. This utility model has excellent breathability, avoiding stuffiness and discomfort. It forms a three-dimensional air circulation system through an array of ventilation holes and a side annular ventilation channel, which greatly improves heat dissipation efficiency and reduces the accumulation of moisture and heat caused by prolonged sitting. The diameter of the ventilation holes is designed to be 3-8mm, which can ensure air circulation without affecting the structural strength of the cushion. Compared with traditional closed cushions, it can effectively reduce the temperature of the buttocks, reduce sweating, and improve comfort, making it especially suitable for long-term office work, driving and other scenarios.

[0016] 2. The zoned shock absorption design of this utility model conforms to ergonomics. The gradient height shock absorption protrusions can provide differentiated support according to the pressure distribution of the human body. The ischial tuberosity area uses a higher protrusion to enhance the support and relieve pressure; the thigh and buttocks area uses a lower protrusion to provide soft cushioning and avoid compressing blood vessels and nerves; the shock absorption protrusions are made of silicone material, which is both elastic and durable, and is less prone to collapse and deformation than ordinary sponge.

[0017] 3. This utility model is anti-slip and stable, making it safer to use. The bottom of the seat cushion has anti-slip texture, which can increase the friction with the seat and prevent sliding and displacement. The bottom layer is made of TPU waterproof layer, which not only prevents slipping but also prevents liquid from seeping in, making it easy to clean and maintain.

[0018] 4. This utility model has a simple structure, low cost, and is easy to mass-produce. It adopts an integrated molding process, eliminating the need for complex internal structures such as springs or honeycomb supports, thus reducing production costs. The modular design, array of protrusions, and ventilation holes make it easy to adjust the size and shape to meet different seat needs.

[0019] 5. This utility model is durable, easy to clean, and has a long service life. The silicone shock-absorbing protrusions have good anti-aging properties and are not easily deformed after long-term use. The vent design can prevent dust accumulation, and with the waterproof bottom layer, it can be cleaned simply by wiping, making maintenance convenient. Attached Figure Description
