The utility model solves the technical scheme that its technical problem adopts: a kind of seat composite endergonic structure, comprise seat back, seat cushions and buffering energy-absorbing structure, the bottom of seat back both sides is arranged on the rear end of the both sides of seat cushions respectively by connecting plate, former and later two installation feet are provided with on the downside of connecting plate, front installation foot is hinged in seat cushions, and described buffering energy-absorbing structure comprises the C type buffer board device be arranged between rear installation foot and seat cushions and the buffering energy-absorbing material layer be arranged on bottom described seat back back and seat cushions, described C type buffer board device comprises C type buffer board and limiting plate, after an end points of C type buffer board and connecting plate, installation foot is hinged, another end points and seat cushions hinged, limiting plate has locating hole and stopper slot, an end points of C type buffer board is hinged at the locating hole place of limiting plate, another end points is movably arranged in stopper slot, locating hole is circular hole, stopper slot is slotted hole, the center of circle of locating hole is positioned on stopper slot center line, described buffering energy-absorbing material layer is the metal thin-wall structure of hollow, filled and process Lu porous material in described metal thin-wall structure, the collision end of described metal thin-wall structure is more low-density foamed aluminium material, end away from collision end is highdensity foamed aluminium material, the described foamed aluminum materials bed of material is divided at least 5 layers, be 0.4g/cm between their density regions
3to 0.8 g/cm
3, the foamed aluminum materials bed of material density of described collision end is 0.4g/cm
3, the density of the foamed aluminum materials bed of material of the described end away from collision end is 0.8 g/cm
3, the density of middle three layers is 0.5 g/cm
3to 0.7 g/cm
3between, each layer density progressively increases progressively from collision end to the end away from collision end.
Described buffering energy-absorbing material layer is the metal thin-wall structure of hollow, in described metal thin-wall structure, be filled with honeycomb porous material.
The line of the forward and backward installation foot of connecting plate is vertical with seat back working face.
C type buffer board device is arranged on automotive seat bilateral symmetry and installs.
The beneficial effects of the utility model:
A kind of automotive seat composite endergonic of the utility model structure, adds C type buffer board device and the buffering energy-absorbing material layer being arranged on described seat back and seat cushions back between seat back and seat cushions; Making automobile when being knocked into the back by the distortion of C type buffer board device and the buffering energy-absorbing material layer simultaneously stability impact energy at seat back and seat cushions back, protecting occupant safety to greatest extent, avoiding occupant's neck to sprain; C type buffer board apparatus structure is simple, changes conveniently; Cushioned material layer improves the energy absorption capability of endergonic structure, proposes the buffering energy-absorbing structure design of a kind of functionally gradient change.
