Stating has loss of weight hollow hole between lumbar support item and postnotum, the backrest frames are integrally formed, the postnotum and waist
Portion's support bar is formed by connecting with backrest frames by secondary.
A kind of composite material backrest for aero seat of the invention, the backrest frames are that size is gradually from top to bottom
The gradual change U-tube to become larger.
A kind of composite material backrest for aero seat of the invention, the material of the backrest frames are fiber reinforcement tree
Resin-based composite, the fiber are carbon fiber or glass fibre, and the resin is phenolic aldehyde, epoxy, PPS or PEI.
A kind of composite material backrest for aero seat of the invention, the backrest frames pass through core model paving, solidification
Extraction core model is prepared afterwards, and the core model material is rubber, foam, gypsum, blowing bag or EPS core model.
A kind of composite material backrest for aero seat of the invention, the lumbar support item are to paste with people's lumbar curve
The arc shape structure of conjunction.
A kind of composite material backrest for aero seat of the invention, the postnotum and lumbar support item with lean on spine
By riveting, welding or be glued between frame.
A kind of composite material backrest for aero seat of the invention, the postnotum and lumbar support item with lean on
The junction of spine frame has reinforced structure, the material of the reinforced structure are as follows: composite material, metal or plastics.
According to the above technical scheme, the beneficial effects of the present invention are: proposing that a kind of composite material for aero seat leans on
Back can effectively simplify preparation process by postnotum and lumbar support item and the secondary connection of backrest frames, improve product qualification rate
And production efficiency, riding comfort can be improved by the way that lumbar support item is arranged, and hollow backrest frames are arranged can be effective
Mitigate overall weight.
