Description

Sectionalized pneumatic mattress

The utility model relates to a kind of parts of chair, relates to a kind of automobile inflating formula chair cushion or rather.

The chair cushion of general automotive seat, form by cushion and back cushion, the shortcoming that this two pad body structure chair cushions exist is: chair cushion is when foaming, its surperficial radian is to cooperate body curve's design, but the people that can not be suitable for all builds, too protruding or too recessed part is arranged unavoidably, especially long-distance travel, sense of fatigue and the problem of aching all over are still very outstanding.Usually adopt and add the way of pillow in the handing-over angle of back cushion and cushion, though solved a part of chronic problem sense problem, the sense of discomfort of back, buttocks still can not get solving.

The purpose of this utility model is a kind of multistage inflatable chair cushion of design, constitutes the filling of each monomer air bag of chair cushion, discharge quantity by control, makes the radian at each position of chair cushion cooperate the body curve fully, guarantees best user mode.

New automobile multistage inflatable chair cushion of the present utility model, constitute by directly being embedded in chair cover back cushion and cushion inner or that set in the seat opening groove, it is characterized in that: described cushion is a monomer air bag, and described back cushion is made up of monomer air bag bustle and monomer air bag back pad;

Also comprise the aerating device and the means of deflation that are arranged on the chair cushion side, are connected with each monomer air bag respectively.

The wireway that described aerating device communicates by inflation purt capsule, with inflation purt capsule, be located at the ventilating control switch that is connected with each monomer air bag air inlet pipe on the wireway duct and form, the ventilating control switch comprises piston, is located at the draw ring of piston one end and is located at the interior bulb stopper of the wireway duct air inlet mouth of pipe.

Described means of deflation, reaching the venting gauge tap that communicates with each blast pipe by the blast pipe that communicates with each monomer air bag forms, the venting gauge tap comprises: be with the separation trough chamber of through hole, the plunger that is positioned at the through hole disjunctor and resistance clamp dog, be located at the compression spring of resistance clamp dog lower end and be located at the valve that compresses the spring other end, valve openings is connected with blast pipe.

Described plunger is provided with oblique cone side wide at the top and narrow at the bottom, and described resistance clamp dog is provided with up-narrow and down-wide oblique cone side, and the ring week of described through hole is provided with the bulge loop bar, and described resistance clamp dog ring has the relative O type ring that staggers with described through hole bulge loop bar on week.

Operation inflation purt capsule and each inflation, venting gauge tap, can control the filling of each monomer air bag, discharge quantity respectively, surface curve with the back of the body of random adjustment chair cushion, waist, buttocks air bag, to match, can keep the sitting posture of the most comfortable and the ride effects that offers the best with seat person's the back of the body, waist, hip curve.

Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing.

Referring to Fig. 1 to Fig. 3, automobile multistage inflatable chair cushion mainly comprises a monomer air bag back pad 10, a monomer air bag bustle 20 and a monomer air bag cushion 30.The rectangular substantially body of each monomer air bag can directly embed installing in seat A set opening groove 1A, 1B, the 1C as shown in Figure 1, also can be embedded in as shown in Figure 2 in the inner space of chair cover B to install.

The

air inlet pipe

11,21,31 that is connected with

air bag

10,20,30 is socketed on respectively on the T jacket mouth 511,512,513 that is opened on the wireway 51 respectively, as shown in Figure 3, inflation purt capsule 50 communicates with wireway 51, and

air bag

10,20,30 and

air inlet pipe

11,21,31 junctions are designed to a bigger empty chamber 101,201,301.Each ventilating control switch is by

piston

52,53,54, be located at the draw ring 521,531,541 of piston one end and be arranged on bulb stopper 101 in the sky chamber 101,201,301 ', 201 ', 301 ' form, to select

air bag

10,20,30.

During the desire inflation,

piston

52,53,54 is pulled outwardly, allow

air inlet pipe

11,21,31 communicate with wireway 51, by 50 inflations of inflation purt capsule, air enters via

air inlet pipe

11,21,31 from wireway 51, simultaneously with bulb stopper 101 ', 201 ', 301 ' on push away, air then enters in the

air bag

10,20,30; And during not air inlet, because of the pressure of air, make bulb stopper 101 ', 201 ', 301 ' withstand 11,21,31 mouthfuls of air inlet pipe, air can be not excessive.

Referring to Fig. 4, Fig. 5, Fig. 6, wherein, Figure 4 shows that the action schematic diagram of resistance clamp dog 461 in top on the gas, Figure 5 shows that the action schematic diagram of depression of plunger 46.

Air bag

10,20,30 the other end then by blast pipe 11 ', 21 ', 31 ' be socketed on the venting gauge tap 40, have and

air bag monomer

10,20, the separation trough chamber 41 of 30 similar numbers, 42,43, in each

separation trough chamber

41,42,43 are provided with through hole 44, be provided with valve 45 in the through hole, the ring of through hole 44 is provided with twice bulge loop bar 441 in week, the built-in bottom that is provided with of through hole is connected with the plunger 46 that hinders clamp dog 461, plunger 46 is provided with oblique cone side 46A, being provided with outward in ring week and the aforementioned bulge loop bar 441 relative O type rings 462 that stagger of resistance clamp dog 461, the opening of valve 45 and blast pipe 11 ', 21 ', 31 ' to join, its content is provided with a compression spring 451.When plunger 46 was depressed, the oblique cone side 46A and the through hole 44 of plunger 46 left suitable space, and bulge loop bar 441 also staggers with O type ring 461 a ventilation slit is arranged, and the air in this

moment air bag

10,20,30 just can discharge along this slit, as shown in Figure 5; Otherwise, when in the

air bag monomer

10,20,30 air being arranged, air pressure can will be on the plunger 46 top, the end face of plunger 46 is sealed through hole 44, and bulge loop bar 441 compels to close with O type ring 461 mutually, bottles up the ventilation slot, air can't be overflowed, as shown in Figure 4.

The utility model has the advantages that chair cushion is constituted by three monomer air bags, the monomer air bag has again inflation and air escape cock separately, and the fluctuating curve of each monomer air bag can cooperate with the body curve fully, guarantees best use state. The fabricated structure of three monomer air bags is convenient to change, and cuts the waste, and practicality is arranged.
