Abstract
Description
Technical Field
[0001] This invention belongs to the field of seat cushion structure, specifically relating to a double-layer foamed sponge for saddles and a double-layer foamed saddle. Background Technology
[0002] With the increasing popularity of cycling equipment and people's growing demand for cycling comfort, the comfort and support performance of saddles or seat cushions have become important design indicators. Existing saddles or seat cushions typically use a single-layer foam material structure. While this structure offers some elasticity and support, it has the following shortcomings:
[0003] A single material with a fixed density cannot simultaneously provide good support and comfort, easily leading to user fatigue or discomfort over prolonged use. Specifically, because the density and elasticity of a single layer of foam are fixed, it cannot balance softness and support during riding, resulting in a poor riding experience. If high-density foam is chosen to improve support, the overall seat cushion will be too hard, easily causing riding fatigue and even buttock pain during long rides. On the other hand, if low-density or soft foam is chosen, although the initial seating feel is better, the seat cushion is prone to "collapse" during riding, causing the rider to sit on the bottom, losing effective support, and thus affecting comfort and riding safety.
[0004] Secondly, existing saddle foam structures are simple and have limited cushioning performance. In complex terrain or vibrating environments, they cannot effectively mitigate impact, affecting the user experience. Existing single-layer foam saddles offer poor coverage and cannot provide a good fit and envelopment, making riders prone to slipping on bumpy roads or at high speeds, affecting handling stability. Furthermore, the single material and structure limit improvements in saddle design and tactile experience, resulting in a stiff appearance that fails to meet market demands for high-end saddles that are "soft, skin-friendly, and have a rounded, aesthetically pleasing design."
[0005] In summary, current technologies have not yet solved the comprehensive optimization problem of saddles and seat cushions in terms of riding comfort, support, and comfort. Therefore, there is an urgent need for a seat cushion structure that combines good softness with efficient support to meet the demands of a higher standard of riding experience. Summary of the Invention

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] Example 1: A double-layer foam sponge for saddle seats
[0024] The double-layer foamed sponge structure for saddles of the present invention includes:
[0025] Upper sponge layer 1: is a soft latex foam sponge, mainly providing a soft and enveloping feeling when sitting;
[0026] Lower sponge layer 2: is a high-density, high-elasticity foam sponge, mainly providing overall contour support and load-bearing support.
[0027] Two layers are stacked along the thickness direction to form a scientific layered structure.
[0028] The thickness of the upper latex foam sponge 1 is designed to be 1 / 2 or 1 / 3 of the total thickness of the double-layer structure, depending on the target vehicle model and riding requirements.
[0029] Preferably, if comfort is the primary focus, a 1 / 2 layer ratio can be selected to enhance the soft, enveloping feel;
[0030] If athleticism is the primary focus, a 1 / 3 layer ratio can be chosen to enhance the firmness and support of the lower layer.
[0031] Except for the top surface, the upper sponge layer 1 is wrapped around the lower sponge layer on three sides, forming an embedded structure that enhances overall stability and shape consistency.
[0032] Preferably, the upper sponge layer 1 includes an upper front section sponge 11, an upper middle section sponge 12, and an upper tail section sponge 13; the upper front section sponge 11, the upper middle section sponge 12, and the upper tail section sponge 13 are connected by an arc shape, and the upper middle section sponge 12 is slightly lower than the upper front section sponge 11 and the upper tail section sponge 13.
[0033] The lower sponge layer 2 includes a lower front section sponge 21, a lower middle section sponge 22, and a lower tail section sponge 23; the lower front section sponge 21, the lower middle section sponge 22, and the lower tail section sponge 23 are connected by an arc shape, and the lower middle section sponge 22 is slightly lower than the lower front section sponge 21 and the lower tail section sponge 23.
[0034] The upper and lower layers are firmly bonded together through composite foaming or adhesive processes to ensure that the layers will not misalign or separate during long-term riding.
[0035] Preferably, a connecting flange 131 is provided in the upper tail section and a matching connecting groove is provided in the lower tail section to further improve the stability of the assembly.
[0036] The lower layer has a hollow design, forming a cavity that can cover the mounting base plate, enhancing the overall structural strength and fixation effect.
[0037] The outer edge of the lower sponge layer is covered with saddle leather material, which combines waterproofing, aesthetics, and durability.
[0038] The surface of the upper sponge layer can be set with uniform ventilation holes to improve heat dissipation and breathability, and reduce stuffiness and discomfort caused by long-term sitting.
[0039] The cavity of the lower sponge layer and the mating surface of the seat cushion base plate are fitted with a concave-convex structure to form a firm limit and prevent relative slippage between components.
[0040] The lower sponge layer has a limiting protrusion on its outer periphery, which is engaged with the buckle groove of the seat base plate to achieve modular installation and quick disassembly.
[0041] Among them, slow-rebound memory foam can be used to replace the upper latex foam.
[0042] Preferably, the lower layer of high-density, high-elasticity foam sponge adopts a closed-cell structure design, with the foaming ratio controlled at 35%-50% to ensure high resilience and support.
[0043] The upper latex foam sponge uses natural latex or composite latex materials, with the foaming ratio controlled at 55%-70% to ensure good skin-friendliness and soft elasticity.
[0044] Double-layer foaming employs molding processes such as segmented casting, pre-forming and then combining, or integrated secondary foaming to ensure stable and uniform interlayer bonding.
