Abstract
The utility model discloses a fill-up hollow blow-molded chair, in particular to a hollow blow-molded chair used in moving vehicles. The fill-up hollow blow-molded chair of the utility model comprises a seat cushion and a backrest which are integrated through blow molding. The utility model is characterized in that the hollow parts of the seat cushion and the backrest are provided with packing layers, that is, all the hollow parts of the chair of the utility model are filled with filler material such as PU vesicant through the preformed holes on the back of the backrest and the lower backside of the seat cushion, forming packing layers. The utility model is of greater tensile strength and better energy and vibration absorbing performance, greatly increasing the dynamic comfortableness of the chairs of moving vehicles.
Description
Technical field:
The utility model relates to a kind of seat, the filled type hollow blow molding seat that particularly a kind of sports car is used.
Background technology:
Seat uses extensively in daily life.Conventional seat mainly contains sponge seat and injection moulding seat in the market.Wherein the skeleton of sponge seat is a steel material, and tensile strength is low, and energy-obsorbing and damping is poor.In order to overcome the defective of above seat, the hollow blow molding seat has appearred again on the market.These hollow blow molding seats are widely used in public places such as reaching stadiums on the vehicles accessories such as bus, steamer.On December 06th, 2006, just announced a kind of novel blowing seat on the China utility model patent specification CN2843206, it is compared with seat in the past, from tensile strength, though certain improvement has all been done in the energy-obsorbing and damping aspect, but because it is the same with other hollow blow molding seats on the market, the existence of hollow parts causes them in tensile strength, and the energy-obsorbing and damping function aspects still has its limitation.By common hollow blow molding seat is carried out six strength tests, after the pulling force that applies 110%～120% requires, hollow blow molding seat yield deformation under the effect of 220～240kg power.In order to improve the above-mentioned defective of hollow blow molding seat, adapt to the needs of automobile market, develop safe and reliablely, have higher tensile strength, the automotive seat of better energy-obsorbing and damping performance is imperative.
The utility model content:
The purpose of this utility model is to provide a kind of filled type hollow blow molding seat, to solve the technical problem that the hollow blow molding seat has higher tensile strength and better energy-obsorbing and damping performance.
The technical scheme that the above technical problem that solves the utility model adopts is achieved in that a kind of filled type hollow blow molding seat, comprise seat cushion and backrest, seat cushion and backrest blowing are one, it is characterized in that the vacancy forms packed layer in seat cushion and backrest, promptly at all hollow parts of hollow blow molding seat, the reservation aperture that the aperture and the back side, seat cushion bottom are reserved in the back side by the seat upper portion backrest is packed into the blowing agent packing material such as PU blowing agent class, thereby forms packed layer.
The beneficial effects of the utility model are: at all hollow parts of hollow blow molding seat, be packed into blowing agent packing material such as PU blowing agent class, carrying out six strength tests again shows, its tensile strength is the ability yield deformation under the effect of 350～600kg power, thereby has improved the tensile strength of seat greatly.Accurately calculate the amount of filler by repetition test, make filled type hollow blow molding seat possess better energy-absorbing damping performance, this characteristic make seat particularly sports car increase greatly with the dynamic comfortableness of seat.

The specific embodiment:
With reference to accompanying drawing the utility model is described in detail:
The utility model is suitable for any hollow blow molding seat.With this bus hollow blow molding automotive seat of GDS-G25-A is specific embodiment.A kind of filled type hollow blow molding seat with reference to accompanying drawing 3 and accompanying drawing 6, comprises backrest 1 and seat cushion 5, and both are connected as a single entity by the blowing effect, forms the hollow blow molding seat.With reference to accompanying drawing 1,3,4 on bus hollow blow molding automotive seat top hollow 2 parts through backrest 1, the aperture 3 that to open an aperture be 6mm, the blowing agent packing material that injects such as PU blowing agent class forms packed layers 4 at all hollow spaces of backrest 1; With reference to accompanying drawing 2,5,6, through hollow 6 parts of seat cushion 5, the aperture 7 that to open an aperture be 6mm equally also injects the blowing agent packing material such as PU blowing agent class in the seat bottom, forms packed layers 4 at all hollow parts of seat cushion 5; Promptly after forming packed layers 4, all hollow parts of the seat cushion 5 of hollow blow molding seat and backrest 1 promptly form a kind of filled type hollow blow molding seat.
