Problems solved by technology

However, those who are familiar with fiber-reinforced plastic materials know that this kind of material generally uses thermosetting resin as its matrix, so regardless of the hardness of the fiber or the number of layers, it will be cured during the molding process. Make the hole area form an elastic deformation area, in other words, it cannot achieve the intended purpose of making the seat cushion have a shock-absorbing function

Embodiment Construction

[0031] See first Figure 1 to Figure 3 10 is a bicycle seat cushion frame of a preferred example of the present invention, and the seat cushion frame 10 has a narrow and long portion 12 and a wide portion 14 in terms of overall outline. As far as the composition is concerned, it has a body 20 with high rigidity, and three elastic shock-absorbing regions 30, 32, and 34 corresponding to the seating area of ​​the seat cushion.

[0032] The body 20 is formed by stacking one or more layers of carbon fiber woven boards 22 pre-impregnated with epoxy resin. Negative 45 degrees or 90 degrees.

[0033] In order to form the deformation area of ​​each elastic shock-absorbing area, before the main body is heated, pressurized and solidified, three hollow areas 24, 26 and 28 are punched out on each of the fiber-reinforced plastic woven boards 22, and then the uppermost layer is woven A layer of film 40 made of thermoplastic polyurethane (Thermoplastic Urethane, TPU) is laid on the top surf...

Abstract

This invention relates to cushion shell rack with one body and several elastic buffer layers. The body comprises at least one layer of fiber-reinforced plastic boards to form the outline of the shell. The body at least sets one cavern area on the cushion seat area. The elastic buffer layer is composed of non-fiber reinforced plastic material with smaller hardness than the body, which is set on the cavern area.

Description

technical field [0001] The present invention is related to the seat cushion of the riding tool, in particular to a seat cushion shell frame with light weight and elastic shock absorption function. Background technique [0002] Press, U.S. No. 5.348, No. 369 patent discloses a kind of seat cushion that is used for bicycle, and the frame of this seat cushion has a body that is made by hard elastic material (Hard elastic material), and one is respectively filled in the Inside the two holes of the body, there is an elastic body made of soft elastic material (Sonelastic material). Although this kind of seat cushion has better shock absorption function, the disadvantage is that it is too heavy. [0003] In order to solve this problem, U.S. Publication No. 2003 / 0164629A1 patent application discloses an improved bicycle seat cushion. Purpose, in addition, this patent case sets some holes on the main body, and then lays another fiber-reinforced plastic with a hardness smaller than t...
