Description

Novel bus seat

Technical field

The utility model relates to a kind of bus seat, relates in particular to a kind of adjustable back plate thickness and width, but and is designed with the Novel bus seat of wide plane folding and unfolding handrail.

Background technology

At present, the bus seat chair back plate that generally uses is harder, and the passenger can rock because jolting with seat and produce collision when bus travels, and is wound and causes uncomfortable even pain in the back; And some passenger likes taking a nap in public transport, on business hands over seat back to have with a certain distance from the people, makes the passenger lack in bed fulcrum, and the passenger just can be with head rest on window, is easy to make the head part injured when car startup or brake.Passenger's build is different, and is different with width requirement to the thickness of seat back.The seat back that the moulding specification is consistent can't satisfy different build passengers' comfort need.And the bus seat that generally uses lacks the inconvenient passenger side of handrail and leans on, and when the passenger plays mobile phone, arm does not have the place that can support yet during reading.

Summary of the invention

Can not satisfy in order to overcome existing bus seat that all kinds of passengers are comfortable to be taken and the deficiency of the requirement that side is leaned on, the utility model provides a kind of Novel bus seat, possess the structure of common seat and be attached with a manually manual handrail of folding and unfolding in wide plane of the air bag back pad of inflation and a disjunctor, bus seat of the present utility model can satisfy the thickness of the free adjusting seat seat back pad of passenger and the requirement of width, and can when taking, side lean on, handrail is reached the purpose that comfortable leisure is taken as the support of arm or at some pocket-handkerchieves of handrail placement.

The technical scheme that its technical matters that solves the utility model adopts is: this Novel bus seat back plate design is two-layer, and bottom is common bus seat structure, and the upper strata is a manually air bag back pad of inflation.The air bag back pad is shaped as rectangle, and surface design has gripping pattern, but each side is designed with the connecting band of row's manual regulation, and the lower right corner is designed with an air-filled pore.The right side of seat back is designed with wide plane handrail, the handrail below links to each other with seat board, comprise lower chair arm, rotating shaft, upper chair arm, it is long that upper chair arm is provided with laborsaving screw adjustable arm, handrail upper and lower plates face is parallel horizontal surface, upper surface is wider, about the surface be arc and be designed with one deck inflatable pneumatic bag, be convenient to lean on and placing small article.Be fixed with cloth bag below the public transport seat board and be used for depositing inflatable ball.

The beneficial effects of the utility model are: make the passenger manually inflate thickness and the width of adjusting seat chair back plate, and it is comfortable that backboard is that soft material inside is filled with the gas softness, can put down handrail when taking, make things convenient for side to lean on and for arm provides support or the medium and small article of hand are placed on above the handrail, reach the purpose that comfortable leisure is taken.

Fig. 2 is the expansion drawing of connecting band.

The block diagram of Fig. 3 handrail.

Fig. 4 is the front elevation of charge valve.

Among the figure: 1, connecting band, 2, upper chair arm, 3, rotating shaft, 4, lower chair arm, 5, put sliding decorative pattern, 6, air-filled pore, 7, inflating balloon, 8, the connecting band upside part that is stuck, 9, connecting band downside adhesive portion, 10, laborsaving screw.11, Jian Zui, 12, inflatable ball.13, handrail air cushion

The specific embodiment

As shown in Figure 1, rotating shaft 3 connects respectively up and down upper chair arm and lower chair arm, can make upper chair arm hold up or put down by rotation, the front that gripping pattern 5 is imprinted on the air bag back pad contacts with passenger-back, the lower right that air-filled pore 6 is positioned at the air bag back pad is realized inflation and the venting of air bag herein, and connecting band 1 is positioned at each one of air bag back pad both sides and is used for regulating the air bag width.Inflating balloon 7 designs reduce to utilize the space at the downside of seat board, make things convenient for the passenger to pick and place inflatable ball

As shown in Figure 2, the connecting band upside part 8 that is stuck is renovated to the right on connecting band downside adhesive portion 9, reaches the purpose of adjusting the inflation back cushion width by the width of adjusting adhesive portion.

As shown in Figure 3, be designed with a rotating shaft on the handrail, rotating shaft two ends in succession respectively upper chair arm and lower chair arm, can reach the effect that upper chair arm 2 is holded up or put down by the rotating shaft rotation, upper chair arm 2 is designed with laborsaving screw 10, and screw 10 outside portion of the handle arm of forces are long, reach the labour-saving effect, rotary screw 10 can make chair arm 2 inner overlay regions launch, and reaches the purpose of elongation.The upper surface of upper chair arm 2 is wide plane, can place some little article or as the support of arm, upper chair arm about 2 two surfaces are for arc and be designed with handrail air cushion 13, and the handrail air cushion has air-filled pore the same with backboard airbag aeration mode, reaches the purpose of comfortable dependence.

As shown in Figure 4, the sharp mouth 11 of inflatable ball 12 by on it inserts air-filled pores 6 and carries out inflation/deflation, during inflation, sharp mouth 11 inserted fully air-filled pore pushes inflatable ball 12 repeatedly until inflation is finished, and sharp mouth 11 pulled away air-filled pore 6, air-filled pore 6 autoshutdowns.During venting, with half insertion inflatable ball of sharp mouth 11, the extruding gasbag back pad is emitted portion gas, when reaching required thickness sharp mouth 11 is pulled away air-filled pore 6, air-filled pore 6 autoshutdowns.
