Description

Seat cushion

This creation is about bicycle seat cushions, especially those that are made of fiber and thermoplastic materials and thermosetting materials, and that exhibit bending and sagging deformation when subjected to external forces.

The driving force of the bicycle comes from the cyclical pedaling of the rider's legs, while the posture of the rider will fall on the support position of the seat cushion, the pedal and the handlebar, and the hip is placed on the seat cushion as the main weight burden. Therefore, riding comfort depends on the delicate relationship between the buttocks and the seat cushion.

Common bicycle seat cushions are foamed and thermoformed. The foam cushion is mainly provided with a foam material layer and a cover layer on the surface of the plastic base. The seat cushion is heavy in weight, and the foam seat cushion mostly makes a large seating area, so it is quite suitable for urban short-distance commuting and comfortable riding. . The hot-pressed carbon fiber seat cushion can be directly used or combined with the surface of the leather on the surface. The hot-pressed seat cushion has no cushioning and elastic effect compared with the foam cushion, so most of them are made of elongated shapes and often Used for competitions or special road conditions, as well as racing road vehicles.

However, the above-mentioned seat cushions are less likely to cause sultry pain for short-distance and short-time riders, and when faced with the opposite situation, the feet are Cycling and pedaling can make the rider feel uncomfortable on the hips and down, especially the hot-press type seat cushion. To this end, the rider will choose to wear a cushioned bicycle trousers to solve the problem of hip discomfort with the cushion in the bicycle trousers, but only through the cushion to prolong the rider's feeling of discomfort. In particular, the foam cushion is made of foamed cotton, which provides a large amount of deformation through the characteristics of the foam material. However, this design causes the rider to have a large area inside the thigh and is constantly subjected to the cushion during the ride. Rubbing on both sides of the edge, thus forming a rider's downward pressure, riding time and a little longer distance, causing the rider to cross the discomfort. In addition, the cushion pressure is applied for a long time, and most of the weight of the human body is concentrated on the seat cushion, which hinders the supply of local blood and causes tissue ischemia. Therefore, it is necessary to frequently leave the seat cushion and reduce the pressure on the cross. Slow down the pain.
