The invention belongs to the technical field of manned space flight aircraft and particularly relates to a landing buffering device. A multilayered airbag landing buffering seat is characterized by comprising a plurality of layers of airbags (1, 2) which are overlapped up and down; all the airbags (1, 2) are internally provided with stretching cloth (5) which keeps a shape after being inflated; a communication hole (6) is formed in the stretching cloth (5); all the airbags (1, 2) are provided with a plurality of exhausting holes (3) opened by blasting membranes; the total cross area of the exhausting holes (3) of all the airbags (1, 2) are not equal. Before a buffering process is started, all the airbags are fully filled with gas, and a passenger sits on the airbags and is fixed by a binding belt; in the buffering process, the blasting membranes of all the airbags (1, 2) are opened when pre-set pressure is achieved and the pressure is leaked at different speeds, so that the pulse width of an impact load is extended in a large scale, and the peak value of the impact load is weakened. The plurality of layers of airbags are arranged so that the landing buffering seat does not completely lose efficiency when any one airbag is damaged, and the reliability is improved.
