CN2083132U - Gasbag-type sponge-padded seat with airflow orifice - Google Patents

Abstract

The utility model discloses an air bag-type sponge-padded seat with airflow orifices having heat radiating function, which is comparatively suitable for the seats of vehicles. The gasbag-type sponge-padded seat with the airflow orifices mainly comprises a base plate, an air containing bag, an air bag protective sleeve, an airflow channel, a flow guide plate, a flow stopping plate, an elastic body filling layer, etc. By utilizing the convective condition formed by the travelling of a vehicle and an airflow, the airflow flowing into the airflow channel is forced to flow to the surface of the seat to radiate heat. When the heat radiating is not needed, making the flow stopping plate close off the airflow channel is just needed. The elastic body filling layer can improve the full weight of the shape of the seat and the softness when the seat is not charged with air or leaks air.

Description

Gasbag-type sponge-padded seat with airflow orifice

The utility model is that a kind of gas bag formula with air extractor vent adds soft seat position device, relatively is applicable to the seat of the vehicle, also can be used for the seat of furniture.

Existing gas bag formula soft seat position device is applied on the seat of bicycle, its softness, elasticity, comfortable, particularly cushion characteristic has demonstrated preceence preferably, but uses under hot conditions, and also the same with other various soft seats positions have a relatively poor shortcoming of heat dispersion.Under situation about leaking air, will become the shortcoming of hard seat position.

The purpose of this utility model is for people provide a kind of better comformability that has under the high and low temperature condition, under the situation that does not have top off or gas leakage, also can have the gas bag formula soft seat position device than soft seat position condition.

The utility model is applied to the vehicle and is achieved in that it is mainly by bed plate; hold gas bag; hold the gas bag protecting sleeve; flow channel; deflecting plate; compositions such as throttle disk and soft elastomeric objects packed layer; the seat can be by difference required size dimension and geometric configuration moulding; and be fastened with the support unit at seat or be connected; have in the centre of bed plate load center of gravity one group from the bottom surface upwards by holding gas bag; the gas bag protecting sleeve is to the air extractor vent of seat surface; bed plate bottom surface air extractor vent group's both sides are deflecting plates; the topped throttle disk that the scalable aperture is arranged in the bottom surface of bed plate air extractor vent; the inside dimension of the size of throttle disk and flow channel side plate is carried out running-fit and is formed an air horn to be opened/closed road; the small end avidity ground extension of throttle disk is connected on the bottom surface of bed plate; the big end of throttle disk can play open and close arbitrarily and close air flow rate is regulated as required under the control of small end moving connecting mechanism; appearance gas bag and gas bag protecting sleeve and bed plate three air extractor vent should not misplace and should have good unimpeded condition; make the air-flow that enters runner can unimpededly flow to the surface at seat; when vehicle operation is advanced; utilize vehicle operation to advance and this condition of air-flow formation convection current; force the air-flow that enters runner to dispel the heat through the surface that air extractor vent flows to the seat; it is smooth that the outside face that holds gas bag preferably is lined with one deck; soft; solid abrasion resistant lining; to strengthen protective effect; prolonged the service life of holding gas bag; lining should consider that also there is corresponding air extractor vent the ventilating part position; the air extractor vent that holds gas bag is actually breather pipe; it is air tight that breather pipe should guarantee to hold gas bag; the mouth of pipe of breather pipe also can adopt the ventilation cover of air extractor vent, and ventilation cover and tube wall should be fused into one.The inside that holds gas bag also can increase elasticity as required and connect control structure, and air extractor vent also can carry out many groups many places as required and set up separately, and to improve the heat dispersion at seat, holding gas bag, gas bag protecting sleeve and bed plate should have fixing preferably.The soft elastomeric objects packed layer (as sponge etc.) that holds the gas bag inner space has under the situation of certain air pressure charging into gas, because the interaction energy of air pressure is in suspended state to a certain degree, can outclass the elastic force of soft elastomeric objects because of the elastic force of air pressure.So the seat still can demonstrate fully the effect of gas elastic force, after air pressure deficiency or gas leakage, do not have under the situation of air pressure, the elastomeric objects packed layer can play the soft and full effect of profile in seat that keeps.Water conservancy diversion, throttling device are running into the leading flank or the left and right sides face that also can be assemblied in the seat when seat bottom does not have the locus to arrange.Also can save water conservancy diversion, throttling device, only have only simple air extractor vent to dispel the heat.The hole count of air extractor vent also can be arranged arbitrarily according to different purposes and needs with the position.Realization for the seat of furniture: bed plate and the size of holding gas bag should get final product on surface suitable with the size of furniture seat frame foot rest, that air extractor vent should unimpededly directly lead to the seat from the bottom at seat.

With the existing gas bag formula soft seat position (patent No.: 86207103) compare, only need increase flow channel, air extractor vent, throttle disk simply, just can force the part air-flow to enter the surface that runner flows to the seat dispels the heat, improved thermal diffusivity and the traveling comfort of gas bag formula soft seat position under hot conditions, increase soft elastomeric objects packed layer again extremely simply, just can make the seat under the situation of gas leakage, keep soft preferably and full profile.

The utility model is provided by one of them embodiment and the accompanying drawing thereof of following a kind of bicycle seat device:

Fig. 1 is that the master that the bicycle gas bag formula of band air extractor vent adds soft seat position device looks scheme drawing.

Fig. 2 is the schematic top plan view of Fig. 1.

Fig. 3 is that Fig. 2 passes through A---the generalized section of A line.(1) be to set off the bed plate that the gas bag effect is held in supporting.Be to hold gas bag (2) above the bed plate (1); above the appearance gas bag (2) is gas bag protecting sleeve (3); (4) be the soft elastomeric objects packed layer that holds the gas bag inner space; (5) be the air extractor vent of bed plate; (6) be the breather pipe that holds gas bag; (7) be the air extractor vent of protecting sleeve; (8) be and bed plate bottom surface bonded assembly flow channel side plate; (9) be throttle disk; (10) be flow channel; (11) be the part that is connected and fixed of protecting sleeve (3) and bed plate (1), (12) are to be used to the valve inflating and exit, and (13) are to adopt the seat is played supporting; fastening; connect; the existing combiner of angular adjustment and lift action.Hold gas bag (2) and bed plate (1) can be fixed or do not fix.Protecting sleeve (3) and attaching parts (11) can be made into one and directly captive joint bed plate (1); also can finish bed plate (1) and hold interfixing and locating of gas bag (2) by the direct connection of this tissue layer and appearance gas bag protecting sleeve (3) in the topped tissue layer in the bottom surface of bed plate (1).The upper orifice that holds the breather pipe of gas bag also can adopt with tube wall and merge the poroid ventilation cover of all-in-one-piece; also can only there be simple air extractor vent to dispel the heat: the side plate (8) and the throttle disk (9) that can save flow channel (10); utilize the mutual unimpeded condition of bed plate and appearance gas bag and gas bag protecting sleeve three air extractor vent to dispel the heat; or only be that protection is with simple air extractor vent, utilize between this air extractor vent and protecting sleeve and the appearance gas bag as the air gap layer of being reserved among the figure heat radiation of ventilating.
