Abstract

The utility model relates to an inflatable seat of a bicycle, comprising a bottom shell, an outer sheath and a foaming filler arranged between the bottom shell and the outer sheath, wherein, the top surface of the bottom shell is provided with a plurality of through holes and is fixedly provided with an elastic sealing cover whose cross section is in U shape, and an air chamber is formed between the bottom shell and the sealing cover and is provided with at least two air bags inside. When a seat cushion is pressed, the air chamber formed by the sealing cover and a complex air cushion formed by the air bags can increase the damping effect, and the material cost of the filler is saved.

Description

The air-cushion type bicycle saddle cushion

The utility model relates to a kind of parts of bicycle, particularly relates to a kind of air-cushion type bicycle saddle cushion.

As shown in Figure 1, the seat cushion of Regular Bicycle is by drain pan 1, foamed plastic 2 and synthetic skin 3 combine, this foamed plastic 2 (as the polyurethane foamed plastic of climbing over a wall) is filled between what drain pan 1 and the synthetic skin 3, when driving because foamed plastic 2 deformable absorbing vibrations, so it is comparatively comfortable when driving, but, when the bicycle running what rises and falls king-sized road surface, because these foamed plastic 2 deflections own are limited and its distortion is long recovery time, so when the rider sits on the what seat cushion, foamed plastic 2 is the closely knit state of place's what pressurized often, make the shock-proof effect variation, therefore, when driving bicycle, just be easy to feel uncomfortable and can produce the numb phenomenon of aching through Hou after a while.

The purpose of this utility model provides a kind of comparatively comfortable and have an air-cushion type bicycle saddle cushion than the Cui shock-proof effect at what.

The utility model provides a kind of air-cushion type bicycle saddle cushion, comprises a drain pan, a crust and is located at a foam filler between this drain pan and the crust, and its feature is at what:

This drain pan is provided with most perforation;

This seat cushion also comprises a capping and most air bag;

This capping is to have elasticity and section to take the shape of the letter U and be installed in the housing that this drain pan top coats this perforation, innerly forms an outer air chamber;

This air bag is to be made by the rubber-like material, respectively form air chamber in the osed top in each air bag, this air bag is horizontally set on this capping below and position outside this in air chamber, be somebody's turn to do between outer gas chamber sidewall and air bag and between air bag and air bag and respectively have a gap, can make these air bags extensional deformation in good time when bearing external force, therefore, not only can increase shock-proof effect and the traveling comfort that drives, the material cost that also can save weighting material.

Described air-cushion type bicycle saddle cushion, its feature are at what:

This air bag can be the circle shape.

Described air-cushion type bicycle saddle cushion, its feature are at what:

This perforation can be located at drain pan back segment place.

In sum, the advantage of the utility model air-cushion type bicycle saddle cushion is:

1. form an outer air chamber 42 on the drain pan 10 because capping 40 of the present utility model is cemented at, become the ground floor air cushion, and should be provided with most air bags 50 in the outer air chamber 42, become second layer air cushion.Therefore, when the bicycle running what jolts the road surface and makes the interrupted pressurized of capping 40, because of the elastic force of answer naturally and the support effect of these air bags 50, making this capping 40 can not be depression because of the discharge of gas is attached on the drain pan 10, just these air bags 50 make capping 40 have the force compresses of being subjected to, and the characteristic that release of pressure Hou is rebounded immediately, and by these air bag 50 appropriate extensional deformation effects own, make this seat cushion have shock-absorbing than Cui, buffering effect, therefore, make the rider when driving bicycle, can be by the shock-absorbing of seat cushion, buffer action, and can reach the effect of shock-absorbing.

2. because the utility model is to replace weighting material 30 space partly by gas, so when manufacturing, can reduce the quantity of material of this weighting material 30, with cost-cutting.

Below by Cui embodiment and accompanying drawing air-cushion type bicycle saddle cushion of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the exploded perspective scheme drawing of general seat cushion.

Fig. 2 is the exploded perspective scheme drawing of the utility model one than Cui embodiment.

The scheme drawing of Fig. 3 when to be that the utility model is above-mentioned do not suffer oppression than Cui embodiment.

The action scheme drawing of Fig. 4 when to be that the utility model is above-mentioned suffer oppression than Cui embodiment.

As shown in Figure 2, air-cushion type bicycle saddle cushion of the present utility model comprises a drain pan 10, a crust 20 and the foam filler (as PU) 30 between this drain pan 10 and crust 20.Because said structure is a conventional art, so no longer be described in detail at this.This seat cushion also comprises a capping 40 and most air bag 50 in addition.

This drain pan 10 is made by plastic material, is provided with most perforation 11, in the present embodiment, these perforation 11 be the position at these drain pan 10 back segment places, the position of rider's buttocks contact just.

As shown in Figure 3, this capping 40 is to have the lid that elasticity and section take the shape of the letter U, and its peripheral sidewall 41 is cemented at this drain pan 10 end face places, and this capping 40 coats these perforation 11, and outside inside forms one air chamber 42.

As shown in Figure 3, these air bags 50 are to make with the elastomeric material of tool, be provided with four air bags 50 in the present embodiment, each air bag 50 is rounded, and form air chamber 51 in osed tops in that these air bags 50 are inner, and these air bags 50 are horizontally set on the internal face of capping 40, make 50 in these air bags outside in the air chamber 42, and be somebody's turn to do between outer air chamber 42 sidewalls and the air bag 50, and all has a gap between air bag 50 and the air bag 50, when these air bags 50 bore external force, this outer air chamber 42 has enough spaces can supply these air bag 50 extensional deformations.

As shown in Figure 3, when this seat cushion is not pressed down by external force (just when the rider does not drive bicycle), this weighting material 30 is fluffy, and should have maximum space by outer air chamber 42.

As shown in Figure 4, when this seat cushion is pressed down by external force (just when the rider drives bicycle), these weighting material 30 pressurizeds, make rubber-like capping 40 and each air bag 50 relative pressurizeds, at this moment, should outer air chamber 42 gas inside can bore a hole and 11 release from these, and these air bags 50 can be in air chamber 42 extensional deformation, and increase the shock-proof effect of seat cushion by means of its compression elasticity.
