Description

Technical Field

[0001] This utility model relates to the field of cycling seat structure, and in particular to a shock-absorbing and breathable cycling seat. Background Technology

[0002] Cycling gear has been recognized as one of the high-tech sports equipment available today, and is increasingly favored by athletes and cycling enthusiasts. Cycling apparel plays an important role in maintaining the body's athletic function, reducing injuries caused by cycling, and improving the cyclist's athletic ability. Cycling apparel usually has a saddle pad sewn into the crotch area to protect the buttocks and inner thighs from constant friction between the buttocks and inner thighs and the bicycle seat during cycling, which can cause chafing.

[0003] Currently, most cycling apparel saddles use single-density foam or silicone materials. Their shock absorption performance relies on the static compression and rebound characteristics of the material, making it difficult to adapt to the dynamic load changes in the ischial tuberosity area during cycling. Especially under high-speed pedaling or complex road conditions, traditional saddles lack vertical elastic deformation space, causing the impact energy from the bones to be directly transferred to the soft tissue, easily leading to local high pressure and blood circulation disorders in the ischial tuberosity area. At the same time, although the closed foam structure has basic cushioning capabilities, it lacks effective airflow channels inside, and the accumulation of sweat during long rides can easily cause heat-induced skin damage, failing to achieve a dynamic balance between shock absorption and heat dissipation. Utility Model Content

[0004] In view of the shortcomings mentioned above, this utility model provides a shock-absorbing and breathable cycling seat.

[0005] The present invention adopts the following technical solution:

[0006] A shock-absorbing and breathable cycling seat includes a 3D-printed shock-absorbing pad fitted into cycling apparel. The shock-absorbing pad is formed by continuously stacking layers of filaments extruded from a thermoplastic material, wherein:

[0007] The filaments of two adjacent deposition layers are arranged in an interlaced mesh, so that the upper filaments have space for bending and deformation in the vertical direction, forming a shock-absorbing elastic structure.

[0008] The filaments in each deposition layer maintain uniformly spaced gaps, which form a breathable channel that runs through the entire thickness of the shock-absorbing pad.

[0009] In one possible implementation, inclined guide surfaces are provided at the edges on both sides of the damping pad in the thickness direction.

[0010] In one possible implementation, the guide surface is composed of multiple layers of annularly distributed filaments stacked together.

[0011] In one possible implementation, the shock-absorbing pad includes a pelvic floor support and an ischial support. The ischial support is provided on both sides of one end of the pelvic floor support, and the ischial support is arranged at an angle relative to the pelvic floor support, so that the pelvic floor support corresponds to the crotch area of ​​the cycling suit, and the two ischial support parts correspond to the two sides of the buttocks area of ​​the cycling suit respectively.

[0012] In one possible implementation, the thickness of the ischial support portion is greater than that of the pelvic floor support portion.

[0013] In one possible implementation, both sides of the pelvic floor support in the thickness direction and both sides of the ischium support in the thickness direction are provided with inclined guide surfaces at their edges.

[0014] In one possible implementation, the guide surface is composed of multiple layers of annularly distributed filaments stacked together.

[0015] In one possible implementation, a fixed pad is fitted inside the cycling suit, the shock-absorbing pad is embedded in the pad, the joint area of ​​the pelvic floor support and the ischium support forms an arc-shaped transition groove through the guide surface, and the pad is sewn with reinforcing stitches along the edge of the pelvic floor support and the edge of the ischium support, as well as the groove.

[0016] In one possible implementation, the pad includes a first surface layer and a second surface layer that are bonded together, with the shock-absorbing pad embedded between the first surface layer and the second surface layer.

[0017] In one possible implementation, both the first and second surface layers are made of sponge material.

[0018] As described above, this invention offers the following advantages compared to existing technologies: The shock-absorbing pad is constructed from layers of interlaced thermoplastic filaments arranged in a mesh pattern. The filaments in the upper layers are supported by those in the lower layers. During cycling, the hips repeatedly press down on both sides of the shock-absorbing pad. This structure allows the filaments at the pressed areas to deform vertically, converting the hip pressure into elastic potential energy, thus providing shock absorption. Simultaneously, the gaps between adjacent filaments in each layer form a through-type ventilation channel, accelerating air circulation on the hip contact surface. The overall structure, through flexible cushioning and a porous structure, achieves synergistic optimization of shock absorption, ventilation, and heat dissipation, significantly improving cycling comfort.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0026] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0027] This utility model provides a shock-absorbing and breathable cycling seat, as shown in the attached... Figures 1 to 3 As shown, the cycling saddle includes a 3D-printed shock-absorbing pad 2 embedded within the cycling apparel. The shock-absorbing pad 2 is embedded within a liner 1, and the liner 1 is attached and fixed to the cycling apparel to keep the shock-absorbing pad 2 positioned in the corresponding crotch and buttock areas of the apparel. The liner 1 includes a first surface layer 11 and a second surface layer 12 that adhere to each other. The shock-absorbing pad 2 is embedded between the first surface layer 11 and the second surface layer 12, forming a composite sandwich structure of first surface layer 11-second surface layer 12-shock-absorbing pad 2. The edges of the second surface layer 12 and the first surface layer 11 are bonded together using a hot-pressing process. Reinforcing seams are sewn along the outer periphery of the liner 1 to ensure the shock-absorbing pad 2 is securely embedded between the first surface layer 11 and the second surface layer 12. Furthermore, both the first surface layer 11 and the second surface layer 12 are made of sponge material, which helps to improve the overall shock absorption effect of the cycling saddle.

[0028] As attached Figure 4 and 5As shown, the shock-absorbing pad 2 is formed by continuously stacking layers of filaments 21 extruded from thermoplastic material. The filaments 21 of adjacent upper and lower deposition layers are arranged in a staggered mesh pattern, so that the filaments 21 of the upper deposition layer are supported by the filaments 21 of the lower deposition layer, with the portion between adjacent lower filaments 21 suspended. This allows the upper filaments 21 to have space for bending and deformation in the vertical direction. Specifically, when the rider is in a riding posture, the ischial tuberosities of both hips repeatedly press down on both sides of the shock-absorbing pad 2 during the alternating pedaling motion. The periodic load on both sides of the ischial tuberosities causes the filaments 21 to bend and return in a directional manner in the vertical direction, achieving dynamic storage and release of elastic potential energy, thus creating an elastic shock-absorbing effect during riding.

[0029] The filaments 21 of each deposition layer maintain uniformly spaced gaps, which form a breathable channel 201 that runs through the entire thickness of the shock-absorbing pad 2. This structure allows the three-dimensional network of uniformly distributed gaps between each deposition layer to be connected along the thickness direction, accelerating air circulation through capillary effect. This allows the rider's buttocks to form a continuously convective microclimate environment with the contact surface of the riding seat of this utility model, which is conducive to breathability and heat dissipation. At the same time, under the synergistic effect of the deformation recovery force of the filaments 21 and the airflow exchange in the gaps, the shock absorption performance and breathability are improved simultaneously.

[0030] As attached Figure 4 As shown, both sides of the shock-absorbing pad 2 in the thickness direction have inclined guide surfaces 22 at their edges. During changes in riding posture, these guide surfaces 22 can guide the soft tissue to slide naturally, avoiding the concentration of skin shear stress caused by traditional right-angled edges, thus improving riding comfort. Preferably, the guide surfaces 22 are constructed by progressively stacking multiple layers of annularly distributed filaments 21 into the shock-absorbing pad 2, forming a biomimetic gradient buffer interface. This multi-layered annularly distributed filament stacking structure increases the flexibility of the guide surfaces 22, making the edges of the shock-absorbing pad 2 softer to conform to the curve of the buttocks.

[0031] Continue to refer to the appendix Figure 4The shock-absorbing pad 2 includes a pelvic floor support 23 and an ischial support 24. The ischial support 24 is located on both sides of one end of the pelvic floor support 23, and the ischial support 24 is arranged at an angle relative to the pelvic floor support 23. This allows the pelvic floor support 23 to correspond to the crotch area of ​​the cycling jersey, and the two ischial support 24 to correspond to the sides of the buttocks of the cycling jersey. When the cyclist is in a cycling posture, the ischial support 24 adapts to the position of the ischial tuberosities, and the pelvic floor support 23 extends along the physiological curvature of the pelvic floor muscles and presses against the saddle nose of the bicycle seat. In this structure, the angled ischial support 24 acts like an ergonomic tray, precisely absorbing the downward pressure from the ischial tuberosities. The pelvic floor support 23, which extends along the curvature of the pelvic floor muscles, forms a flexible lever, which transforms the fulcrum reaction force of the bicycle seat saddle nose into natural support for the pelvic floor muscles. This creates a composite structure of rigid support point and flexible transmission surface, avoiding the pressure friction of traditional bicycle seats on sensitive areas. This allows the shock-absorbing pad 2 to achieve a dual balance of skeletal support and muscle pressure relief during riding.

[0032] Furthermore, inclined guide surfaces 22 are provided at the edges of both sides of the pelvic floor support 23 in the thickness direction and both sides of the ischium support 24 in the thickness direction. These guide surfaces 22 are the same as those provided on the outer periphery of the shock-absorbing pad 2. During dynamic switching of riding posture, the guide surfaces 22 prevent friction damage caused by excessive displacement of the soft tissue of the buttocks, allow for natural fine-tuning during hip joint movement, and ultimately form a load-bearing interface that combines pressure diffusion, motion tracking, and boundary protection.

[0033] As described above, the reinforcing seams sewn along the outer periphery of the shock-absorbing pad 2 in the pad 1 are equivalent to the reinforcing seams sewn along the edges of the pelvic floor support 23 and the ischial support 24 on the pad 1. It is worth noting that in a structure where inclined guide surfaces 22 are provided at the edges on both sides of the thickness direction of the pelvic floor support 23 and both sides of the thickness direction of the ischial support 24, the joint area between the pelvic floor support 23 and the ischial support 24 forms a transitional groove 202 through the guide surface 22. The pad is also sewn with reinforcing seams along the groove 202, and the seam trajectory matches the length direction of the groove 202, forming a dynamic boundary that constrains the deformation of the shock-absorbing pad 2, further reinforcing the pelvic floor support 23 and the ischial support 24 without affecting their relative swaying during the process of conforming to the cyclist's buttocks. During cycling, the seam at the groove 202 restricts the overall deformation of the shock-absorbing pad 2 while allowing the pelvic floor support 23 to deflect slightly with the swing of the sacrum and coccyx. At the same time, the ischial support 24 can also adjust its posture autonomously according to the changes in ischial pressure.

[0034] Furthermore, the thickness of the ischial support portion 24 is greater than that of the pelvic floor support portion 23. This difference in thickness between the ischial support portion 24 and the pelvic floor support portion 23 allows the thicker ischial support portion 24 to form a mechanical anchor point supporting the buttocks, diverting the concentrated impact force of the ischial tuberosities towards the bicycle seat, thus improving shock absorption. The gradually thinning pelvic floor support portion 23, on the other hand, enhances its flexibility to adapt to the physiological curve of the cyclist's pelvic floor muscles, transforming the reaction force from the saddle nose of the bicycle seat into natural support for the lumbosacral region.

[0035] In summary, the shock-absorbing pad 2 of this invention is constructed by layering interlaced thermoplastic filaments 21, allowing the filaments 21 of the upper layers to be supported by those of the lower layers. During cycling, this structure enables the filaments 21 to deform vertically, converting hip pressure into elastic potential energy for shock absorption. Simultaneously, the gaps between adjacent filaments 21 in each layer form a through-type ventilation channel 201, accelerating air circulation to the hip contact surface. The shock-absorbing pad 2 is divided into a pelvic floor support section 23 and an ischium support section 24. The former transmits the reaction force from the fulcrum at the saddle nose of the bicycle seat, while the latter precisely disperses ischium pressure. Both sections have guide ramps formed by stacked annular filaments 21 at their edges, guiding natural deformation of soft tissue and reducing friction damage. The overall structure achieves synergistic optimization of shock absorption, ventilation, heat dissipation, and ergonomic fit through flexible cushioning and a porous structure, significantly improving cycling comfort.

[0036] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
