Abstract

The utility model relates to an air bag and is characterized by consisting of two S-shaped hanging rack which can adjust height, a U-shaped air bag pillow, two rubber inflation tubes and a trapezoidal air bag connected in turn. The air bags are all made up of polythene plastic single-side plain weave cloth, thereby increasing tensile resistance and ventilation property. The trapezoidal air bag changes an angle when people sit and stand to increase dependent area of back of people; the U-shaped air bag pillow is added on cervix to relieve fatigue of cervical muscle; the whole air bag makes a change on gravity center of human body, thereby achieving effects of fatigue relief, safeness and comfort.

Description

Air bag

The utility model relates to a kind of air bag, the particularly a kind of air bag that can regulate the height relieving fatigue.

At present, its backrest of the employed seat of people is vertical with seat surface or tilts a little, sitting in the above feels that easily waist and neck ache, this is because its design is just simply sat and leaned on, the demand that does not meet the human body structure, waist and head are contacting of point with seat during sitting, make psoas and cervical muscle in tension always, very easily cause DOMS, produce fatigue.

The novel purpose of this use provides a kind ofly can regulate the air bag that highly reaches relieving fatigue.

The purpose of this utility model is achieved in that air bag by the height-adjustable hanger of a pair of serpentine, the height-adjustable air-bag pillow of " U " shape, and two inflated rubber pipes and a trapezoidal air bag are formed by connecting in turn.Side at trapezoidal air bag has an inflation to chew, and uses for whole airbag aeration, venting.Whole air bag can free folding before unaerated.The shape that inflation back " U " shape air-bag pillow occurs meets the profile of neck and head, has increased the support face greatly.

The air bag height regulating frame is a serpentine, not only can fix " U " but shape air-bag pillow but also free adjustment height because be a pair of serpentine hook, institute is so that " U " shape air-bag pillow is very steady.Air bag has increased stretching resistance and gas permeability by vinyon single face heat seal one deck plain.Trapezoidal air bag front shape can be made according to different demands, its objective is: 1, increase gas permeability; 2, waist is played massage effect; 3, elegant in appearance.When the people is sitting on the chair, headrest is on " U " shape pillow, lean against when trapezoidal air bag, change the angle of original sitting, the support face of waist has been increased, removed the tense situation of waist and musculi colli, and move after making the center of gravity of human body, back pressure reduces, and makes the people be difficult for producing fatigue, reaches comfortable effect.

Below in conjunction with accompanying drawing embodiment of the present utility model is further specified.

Fig. 1 is the utility model overall structure figure;

Fig. 2 is the utility model serpentine hanger schematic diagram;

Fig. 3---Fig. 4 is the utility model " U " shape air-bag pillow schematic diagram;

Fig. 5---Fig. 8 is the trapezoidal air bag schematic diagram that originally makes utility model;

In the drawings, the air bag height regulating frame is made up of a pair of " " shape hanger (1) and a pair of " " shape air-bag pillow hanger (5), (1), (5) form the serpentine hanger, a pair of serpentine hanger was connected by the horizontal dawn (2), (1), there is slotting (4) (5) junction, set screw (3) is used for regulating height, and " " shape hanger is used for fixing " U " shape air-bag pillow (6) simultaneously.

There is a pair of connection mouth (7) at two ends, bottom, back at " U " shape air-bag pillow, be connected with an end of inflated rubber pipe (8), be a trapezoidal air bag (10) below, there are two connection mouths (9) at the top two ends of trapezoidal air bag, be connected with the other end of inflated rubber pipe (8), there is a valve nozzle (11) a side (13) at trapezoidal air bag, makes disposable the finishing of inflation, and the another side is apneustic chews.The front of trapezoidal air bag is raised line (12).(14) being trapezoidal air bag bottom surface, is (15) above the trapezoidal air bag.

Claims

1. air bag is characterized in that: the air bag back cushion, and air-bag pillow, the serpentine hanger that can hang on the chair is linked in sequence.

2. air bag according to claim 1 is characterized in that: the front of air bag back cushion has irregular concave and convex strip.

3. air bag according to claim 1 is characterized in that: the serpentine hanger that is connected with " U " shape air-bag pillow can be regulated the height of " U " shape air-bag pillow.
