Abstract
The utility model provides a car back row cushion, is including sitting people region and peripheral region, and every region all includes cushion core and seat covering, sitting people's cushion core regional and peripheral region and constituting by upper and lower two -layer expanded material, upper and lower two -layer expanded material passes through the complementary structure, and the scarf joint is continuous each other. Adopt the utility model discloses a device has improved collision safety index, has reduced weight, has improved the shock -absorbing capacity, has promoted passenger's travelling comfort: and has the sound of an inhaling function.
Description
Technical field
The utility model relates to automobile component, particularly relates to a kind of automobile back row cushion.
Background technology
The structure of the automobile back row cushion of prior art has two kinds below: 1, the cushion core outsourcing seat covering of the inner embedding steel wire of PUR (polyurethane foam material).2, outsourcing seat covering after the embedding steel wire of PUR+EPP (PP foam material) embedding steel wire.The first scheme seat is heavier, price, and not environmentally, safety performance rank is low, is difficult to by the Collision test requirement in C-NAP regulation.Monolithic seat is partially soft.First scheme increases on level of security, but entirety does not have pure PU (polyurethane) soft and substantially airtight, and travelling comfort is poor, and level of security is not also high especially.And the fixed form of cushion frame is all use metallic framework with the moulding elastic conjunction embedded in panel beating.The tooling cost of EPP body is high.
Utility model content
The purpose of this utility model, exactly in order to solve the problem, provides a kind of novel automobile back row cushion.
In order to achieve the above object, the utility model have employed following technical scheme: a kind of automobile back row cushion, and comprise and sit people region and peripheral region, each region comprises cushion core and seat covering; The cushion core of described seat people region and peripheral region is formed by upper and lower two-layer expanded material, and upper and lower two-layer expanded material is rabbeted connected by complementary structure mutually.
The cushion core upper strata in described seat people region is low-density polyurethane expanded material, and lower floor is the hollow PP foam material of straw shape with ventilative sound absorption function.
The density of described low-density polyurethane expanded material is 50kg/m
3.
The cushion core upper strata of described peripheral region is high density polyurethane expanded material, and lower floor is high-strength polypropylene expanded material.
The density of described high density polyurethane expanded material is 70kg/m
3.
Under the high-strength polypropylene expanded material of the tetrapod of automobile back row cushion, post the double-deck mushroom head hasp for automobile back row cushion being fixed on the male and female structure on vehicle body sheet metal respectively.
Compared with prior art, the utility model has the following advantages:
One, collision safety index is improved: use dual density construction, can available protecting passenger.The displacement of passenger's preshoot during minimizing traffic accident.Improve the safe class of C-NAP collision.
Two, effectively weight is reduced: use dual density construction, centre can use the raw material than original less dense.Effectively can reduce the weight of whole seat.
Three, cushion characteristic is improved: the SEPP using high strength, the cushion characteristic of lifting 20% of foaming than common PP when same proportion.
Four, there is sound absorption function: use PEPP, effectively can absorb the noise in car, promote NVH index.
Five, promote passenger comfort: centre is born passenger weight part and used lower density PUR and PEPP, sit softer more flexible than pure PUR structure and PUR+EPP structure of sense.Use PEPP, whole seat cushion can be breathed freely.
Six, reduce cost of parts: cancel steel-wire carcass, effectively can reduce the cost of steel wire and steel-wire carcass and add the work mould inspection in man-hour and drop into; Cancel skeleton inserts inside EPP, reduce by one technique process, improving productivity 30%.
Seven: use mushroom hasp fixing replacement metal to embed fixing, make whole seat more even with the distribution of the fixed position of panel beating, fix unlike metallic framework, only have several points of local.When high-speed crash seat with the shearing force of panel beating larger evenly.
Accompanying drawing explanation
Fig. 1 is of the present utility modelly just cuing open structural representation (automobile coordinate Y-direction cutaway view);
Fig. 2 is that structural representation (automobile coordinate X is to cutaway view) is cutd open in side of the present utility model.
Detailed description of the invention
See Fig. 1, Fig. 2, automobile back row cushion of the present utility model, comprise and sit people region 1 and peripheral region 2, each region comprises cushion core and seat covering (seat covering is out not shown); The cushion core sitting people region and peripheral region is formed by upper and lower two-layer expanded material, and upper and lower two-layer expanded material is rabbeted connected (coordinating see Fig. 2) mutually by complementary structure.
The cushion core upper strata 11 sitting people region 1 is low-density polyurethane expanded material, and lower floor 12 is for having the hollow PP foam material of straw shape of ventilative sound absorption function.The density of above-mentioned low-density polyurethane expanded material is 50kg/m
3.
The cushion core upper strata 21 of peripheral region 2 is high density polyurethane expanded material, and lower floor 22 is high-strength polypropylene expanded material.The density of above-specified high density polyurethane foam material is 70kg/m
3.
At the high-strength polypropylene expanded material 22 times of the tetrapod of automobile back row cushion, post the double-deck mushroom head hasp 3 for automobile back row cushion being fixed on the male and female structure on vehicle body sheet metal respectively.In the high-strength polypropylene expanded material 22 of the tetrapod of automobile back row cushion, be also equipped with for covering being coated on injection moulding card article 4 on body.
Claims (6)
