Abstract
A kind of inflation mechanism for Upholstered sofa regulation headrest position angle, including bottom plate, the pillow plate being connected through the hinge with bottom base plate, between bottom plate and pillow plate and the air bag of pillow plate around hinge rotation and the aerating and exhaust device of gas can be promoted.The comfort level that this technology is simple in construction, cost is low, has had.
Description
Technical field
The utility model patent technology belongs to software function sofa accessory technical field, is that one kind can be used for specifically
The method for adjusting the angle of the head support position of Upholstered sofa.
Background technology
Have the method for the height on numerous regulation seat heads on the market at present, as Publication No. 203262722U,
Technology disclosed in the patents such as CN204149900U, CN203435994U, CN105501083A, the support of seat head can be achieved
The regulation of the height at position, so as to improve the comfort level of the seat sense of human body.But all these technologies all can only be by filling to air bag
The change of the shape of air bag reaches the change of the height of regulation seat headrest positions before and after deflation, is Soft Roll for headrest position
Upholstered sofa, the height of these regulations does not reach the requirement of comfort level or the requirement attractive in appearance of outward appearance, and can only adjust headrest portion
The height of position support is unable to adjustment angle.What the mechanism of other other headrest adjustable angles was all is hinge or electronic pushes away
Bar activation lever mode realizes the shortcomings that inconvenient for use or high expensive be present.
Utility model content
The purpose of this utility model is to be directed to above the deficiencies in the prior art, and design one kind can reach regulation headrest position
The function of angle, the inflation mechanism of Upholstered sofa simple in construction regulation headrest position angle.
The utility model purpose can be achieved through the following technical solutions, a kind of inflation for being used to adjust sofa headrest angle
Mechanism, including bottom plate 1, the pillow plate 2 being connected with the bottom of bottom plate 1 by hinge 3, between bottom plate 1 and pillow plate 2 and pillow can be promoted
The air bag 4 and the aerating and exhaust device 5 of air bag 4 that the around hinge 3 of plate 2 rotates.
A kind of described inflation mechanism for being used to adjust sofa headrest angle, it is rested the head on, and plate 2 rests the head on plate 20 by center, plate is rested the head in left side
21 and right side pillow plate 22 form；Plate 21 is rested the head in left side and right side pillow plate 22 passes through hinge left plate hinge 30, right plate hinge respectively
31 are respectively arranged on the both sides of center pillow plate 20；Between bottom plate 1 and center pillow plate 20, left side pillow plate 21 and right side pillow plate 22, point
She You not center pillow plate air bag 40, left side pillow plate air bag 41 and right side pillow plate air bag 42；Aerating and exhaust device 5 can be rested the head on control centre
The inflation/deflation of plate air bag 40, left side pillow plate air bag 41 and right side pillow plate air bag 42.
A kind of described inflation mechanism for being used to adjust sofa headrest angle, its air bag 4 is one or more gas
The overlapping composition of capsule.
A kind of described inflation mechanism for being used to adjust sofa headrest angle, its center pillow plate air bag 40, left side pillow plate gas
Capsule 41 and right side pillow plate air bag 42 are respectively the overlapping composition of one or more air bag.
Compared with prior art, the utility model has the advantage of：
1st, it is simple in construction；Using pneumatic actuation, air bag is executive component, with existing push rod or other driving structure phases
Than structure is simpler.
2nd, cost is lower；This technology uses Pneumatic drive system, it is possible to achieve the angle of the headrest of function sofa seat is adjusted
Function is saved, cost is lower.
3rd, more preferable comfort level；This technology uses executive component of the air bag for function, has suitable elasticity, and be to pass through
The angle of adjustment sofa headrest position sits sense and other existing regulation headrest positions height so as to adjust the seat curve of human body
Structure compared to there is more preferable comfort level.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model；
Fig. 2 is the dimensional structure diagram of another structure of the present utility model；
Fig. 3 is control principle schematic diagram of the present utility model.
Embodiment
As shown in figure 1, a kind of inflation mechanism for being used to adjust sofa headrest angle, including bottom plate 1, lead to the bottom of bottom plate 1
The pillow plate 2 of the connection of hinge 3 is crossed, between bottom plate 1 and pillow plate 2 and the air bag 4 and air bag 4 of pillow plate 2 around hinge 3 rotation can be promoted
Aerating and exhaust device 5.Air bag 4 is three layers overlapping, and three layers of air bag pass through tracheae and three charge and discharge valves of aerating and exhaust device 5 respectively
Connection, aerating and exhaust device 5 include air pump, control circuit, magnetic valve and pressure controller.
As shown in Fig. 2 for the inflation mechanism embodiment that another is used to adjust sofa headrest angle, described one kind is used for
The inflation mechanism of sofa headrest angle is adjusted, it is rested the head on, and plate 2 rests the head on plate 20 by center, plate 21 is rested the head in left side and right side pillow plate 22 forms；It is left
Plate 21 is rested the head in side and right side pillow plate 22 is respectively arranged on center by hinge left plate hinge 30, right plate hinge 31 respectively and rests the head on plate 20
Both sides；Between bottom plate 1 and center pillow plate 20, left side pillow plate 21 and right side pillow plate 22, center pillow plate air bag 40, a left side are respectively equipped with
