The invention discloses a falling self-rescuing device for an elevator, relates to the field of self-rescuing devices, and aims at solving the problems that a passenger without a buffer measure in a car directly impacts the ground to cause hazards of fracture and the like when the elevator falls at a high speed. The falling self-rescuing device for the elevator comprises two upper fixed pipes (1), two lower fixed pipes (2), two rebound springs (3), two damping springs (4), two damping links, two handrail links (6), two seat links (7) and multiple seat ropes (8), wherein the two upper fixed pipes (1) and the two lower fixed pipes (2) are fixedly arranged in the car in a parallel manner; the two rebound springs (3) are arranged in the upper fixed pipes (1); the two damping springs (4) are arranged in the lower fixed pipes (2); the two damping links (5) are inserted into cavities of the upper fixed pipes and the lower fixed pipes; the two handrail links (6) are mounted at the upper parts of the damping links; the two seat links (7) are mounted at the lower parts of the damping links. When the elevator falls at the high speed, the passenger can pull open the seat links (7); the multiple seat ropes are opened to form a soft seat; the passenger is seated on the soft seat, and clasps the handrail links; the buffering is increased by means of the combined action of the rebound springs (3) and the damping springs (4) after the passenger falls to the ground; the hard landing is avoided; the casualty, which is generated due to fracture, of the passenger is avoided furthest.
