BACKGROUND

Field of Disclosure


The present disclosure relates to a vehicle seat. More particularly, the present disclosure relates to a bicycle seat.


Description of Related Art


A bicycle seat is one of the most important parts of a bicycle touching a rider riding the bicycle. The fit of a bicycle seat and the adjustment of a rider's position on the bicycle have close relationships with the rider's overall performance, riding posture and body gravity.


Prior arts attempt to solve this problem of rider's positioning on the bicycle seat. Some manufacturers and designers install a spring support element under the bicycle seat, so that the sore buttocks or tail bone of rider can avoid shock. However, the spring support element will cause resetting shock and pressure to the buttocks or the tail bone of the rider who sitting on the bicycle seat for extended periods of time.


As is known, another bicycle seat is improved by arranging a padding, in which the padding generally is formed from a soft material, and the padding is deformed by a sitting pressure. However, the padding has a large amount of deformation under pressure. The padding is not always suitable to provide a comfortable characteristic to the rider. Furthermore, this kind of “padding” apparatus is usually designed to be softer and thicker. But the padding is too thick to fit the needs of those who need adequate support to finish a long cycling. When the padding has supported a rider for a long time, the padding will increase friction area and prolonged friction to the buttocks or the tail bone of the rider.


On the other hand, if a padding is designed to be hard and thin, the padding will reduce the friction area and cause prolonged friction to the buttocks or the tail bone. However, when the padding has supported a rider for a long time, the padding will cause the pain from concentrated and prolonged pressure to a buttocks or a tail bone of the rider.


SUMMARY

According to one embodiment of the present disclosure, a bicycle seat includes a body. The body has a support portion, a foamed layer and a seat cover. Wherein the body has a deformation space that is filled with a plurality of filler particles, and the deformation space is configured to be deformed by a sitting pressure. When the deformation space is configured to be deformed from the sitting pressure, the particles in the deformation space are sliding and rolling under pressure.

DETAILED DESCRIPTION


FIG. 1 is an exploded view of a bicycle seat according to one embodiment of the present disclosure. FIG. 2 is a cross-sectional view of the bicycle seat shown of FIG. 2.


The bicycle seat includes a pair of parallel support rails 100 and a body 200 attached to the parallel support rails 100. The body 200 has a support portion 210, a foamed layer 220 and a seat cover 230. The support portion 210 is connected to the parallel support rails 100. The foamed layer 220 covers the support portion 210, and the seat cover 230 covers on the foamed layer 220. The foamed layer 220 of the body 200 has two deformation spaces 221. The foamed layer 220 and the seat cover 230 are formed from a soft material, and the support portion 210 is formed from a hard material. These two deformation spaces 221 are sandwiched between the support portion 210 and the foamed layer 220, and each of the deformation spaces 221 is closed by the support portion 210. The deformation spaces 221 are filled with a plurality of filler particles 300, and the deformation spaces 221 will be deformed by a sitting pressure. The filler particles 300 densely fill in the deformation space 221. When the deformation spaces 221 are deformed by a sitting pressure, the filler particles 300 are sliding and rolling under pressure in the deformation spaces 221.



FIG. 3A is a partial cross-sectional view showing filer particles 300 and a deformation space 221 of the bicycle seat of FIG. 2. FIG. 3B is a partial cross-sectional view showing the filler particles 300 and the deformation space 221 of the bicycle seat of FIG. 2, when the filler particles 300 is sliding and rolling under pressure. When the deformation spaces 221 are deformed by a low sitting pressure, the filler particles 300 are sliding and rolling under pressure in the deformation space 221. Because the filler particles 300 roll and hit freely in the deformation spaces 221, the filler particles 300 will reduce the friction between the body 200 and a biker who is sitting on the bicycle seat. When the deformation spaces 221 are deformed by a high sitting pressure, the filler particles 300 are squeezed in the deformation spaces 221. Because the filler particles 300 fill in the deformation spaces 221, the filler particles 300 prevent a biker sitting on the bicycle seat from directing hitting the support portion 210.



FIG. 4 is a cross-sectional view of a bicycle seat according to another embodiment of the present disclosure. FIG. 5A is a partial cross-sectional view showing filler particles 300 of FIG. 4, and a deformation space 221 is without a sitting pressure. FIG. 5B is a partial cross-sectional view showing the filler particles 300 of FIG. 4, and the filler particles 300 are under pressure. Wherein, the foamed layer 220 of the body 200 has two deformation spaces 221. The foamed layer 220 and the seat cover 230 are formed from a soft material, and the support portion 210 is formed from a hard material. The two deformation spaces 221 are opened among the foamed layer 220, and each of the deformation spaces 221 is closed by the foamed layer 220. A portion of the foamed layer 220 and the support portion 210 sustain the bottom of the deformation spaces 221. Therefore, the deformation spaces 221 have large amount of deformation to give the softer feel.



FIG. 6 is a cross-sectional view of a bicycle seat according to the third embodiment of the present disclosure. FIG. 7A is a partial cross-sectional view showing filler particles 300 and a deformation space 221 of the bicycle seat s f FIG. 6, and the deformation space 221 is without a sitting pressure. FIG. 7B is a partial cross-sectional view showing the filler particles 300 and the deformation space 221 of the bicycle seat of FIG. 6, and the filler particles 300 are under pressure. Wherein, the foamed layer 220 of the body 200 has two deformation spaces 221. The foamed layer 220 and the seat cover 230 are formed from a soft material, and the support portion 210 is formed from a hard material. Those two deformation spaces 221 are opened on the foamed layer 220, and each of the deformation spaces 221 is closed by the seat cover 230. A portion of the foamed layer 220 and the support portion 210 sustain the bottom of the deformation spaces 221. Therefore, the deformation spaces 221 have large amount of deformation, and the buttocks or the tail bone of the rider has softer feel.


In FIG. 8, the body of the bicycle seat has three deformation spaces 221. Two of the deformation spaces 221 located at the rear are shaped to receive the buttocks of a rider. One of the deformation spaces 221 located at the front has an important advantage, since it not produce any pressure on the perineum.


In FIG. 9 and FIG. 10, the body of the bicycle seat has one deformation space 221, and the deformation space 221 can be designed to different sizes according to demands.


In FIG. 11, the body of the bicycle seat has two deformation spaces 221, and the two deformation spaces 221 are corresponding to each other to receive the buttocks of a rider.


In FIG. 12, the body of the bicycle eat has one deformation space 221, and the deformation space 221 at the front does not produce any pressure on the perineum.



FIG. 13 is a cross-sectional view of a bicycle seat according to a fourth embodiment. The bicycle seat includes a pair of parallel support rails 100 and a body 200 is attached to a pair of the parallel support rails 100. The body 200 includes a support portion 210 and a seat cover 230. The support portion 210 is connected to the parallel support rails 100. The seat cover 230 covers on the support portion 210. The support portion 210 of the body 200 has two deformation spaces 221. The seat cover 230 is formed from a soft material, and the support portion 210 is formed from a hard material. Those two deformation spaces 221 are sandwiched between the support portion 210 and the seat cover 230, and each of the deformation spaces 221 is closed by the seat cover 230. The deformation spaces 221 are filled with a plurality of filler particles 300, and the deformation spaces 221 will be deformed by a sitting pressure. The filler particles 300 densely fill in the deformation space 221. When the deformation spaces 221 are deformed from a sitting pressure, the filler particles 300 are sliding and rolling under pressure in the deformation space 221.
