The invention discloses a rear-row seat framework which comprises a quartered backrest and a sextant backrest, the outer sides of the quartered backrest and the sextant backrest are assembled on a vehicle body rotating shaft in a hole-shaft matching mode, the rotating shaft on the inner sides of the backrests is arranged on a middle support, and a cover plate is fixed to the middle support through bolts and hooks. And the seat cushions of the quarter backrest and the sixth backrest are assembled on the vehicle body through buckles and hooks. The invention has the following advantages: the outer side of the backrest adopts hole-shaft fit, and the inner side is directly mounted by adopting a shaft, so that the assembly efficiency can be improved, and the precision requirement on peripheral parts is reduced; the bushing design is adopted on the shaft, so that the noise reduction effect can be achieved, and the occurrence probability of abnormal sound is reduced; the seat cushion is limited by the clamping hooks, so that the assembly efficiency is improved; an automatic resetting structure can realize automatic resetting of the backrest, so that the use convenience is improved.
