Specific implementation mode

The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiment is only For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and this practicality cannot be limited with this Novel protection domain.

Embodiment one

As shown in fig. 1, present embodiment discloses a kind of novel bus seat back cushions comprising backboard 10, setting Headrest 20 at the top of backboard and bottom plate 30 in backboard bottom is set.Specifically, it is hollow cavity inside backboard The front of structure, backboard is provided at least one the first vertical strip gab 40, and being provided in first strip gab can The first curved baffle 50 pulled out is provided with and the matched cunning of the sliding of the first curved baffle in the hollow cavity of backrest plate Road (as shown in FIG. 2.), the setting of the slideway should occupy the inner space of backrest plate as few as possible.In practical application In, the length of first strip gab can determine according to different demands, preferably 40-60cm, but be not restricted to this.

The utility model is by above structure, can be by pulling out the first curved baffle come real when passenger takes seat Now to the support of body, to avoid situations such as body centre is unstable in vehicle traveling process from occurring.

Preferably, as shown in Figure 1, the quantity that the first strip gab on backboard is arranged is two, and It is separately positioned on and leans against the positive both sides of version, to play a protective role to body both sides.

Embodiment two

As shown in figs. 4-5,20 inside of resting the head on is that the two sides of hollow structure and headrest offer Article 2 Shape trepanning (not shown in figures) is provided with drawable second curved baffle 21 in the second bar shaped trepanning.Pass through second The setting of curved baffle can play a supporting role to head on both sides, avoid head double swerve back and forth.

Embodiment three

As shown in Fig. 6-7, which is hollow structure, the hollow structure of the first curved baffle It is inside provided with drawable first and extends baffle 51, the length of house type baffle can be suitably lengthened by the setting of the first extension baffle Degree, to the maximum extent surrounds passenger's body to form individual space, while playing protection to the safety of passenger, also The portable important item of passenger can be avoided to be stolen by plagiarist.Moreover it is preferred that the second curved baffle is hollow knot Structure is provided with drawable second in the hollow structure of the second curved baffle and extends baffle.The setting for extending baffle by second Can guard space be formed to head to greatest extent, simultaneously because baffle partial sound can be weakened thus be also avoided that and sleep The influence that the bad person that sleeps snores to other passengers.

In addition, it is not shown in figures, it is hollow cavity structure inside the first curved baffle, the first curved baffle depends on person of modern times It is provided with multiple stomatas, the air entraining pipe and gear of an air pump on the face (that is, when passenger takes against the one side of passenger) of body side The hollow cavity of plate is connected to.It the air inlet of air pump and the cold air outlet of air-conditioning and/or is in communication with the outside, thus can will be empty by air pump The cold air outlet of tune and/or the natural wind in the external world are introduced and are discharged via the stomata on the first curved baffle, so that gas is straight It connects and acts on human body, avoid cold wind and directly act on human body head and the sense of discomfort that generates.In actual use, air pump is logical It crosses air entraining pipe to be connected to each seat respectively, passenger can be adjusted by the way that the switch of air entraining pipe on the seat is arranged.
