The present invention discloses a zero-gravity seat collapsing mechanism, including a base and a seat frame located on an upper side of the base, a rear end of the seat frame being rotatably connected to the base, upper linkage components being rotatably connected to a front end of the seat frame, lower linkage components being rotatably connected to a front end of the base, and the upper linkage component and the lower linkage component being hinged to each other by means of a pin, wherein a collapsing piece is fixedly connected to a side of each upper linkage component, the collapsing piece has an adapter hole located in a lower portion, a collapse channel located in an upper portion, and a weakened portion formed between the adapter hole and the collapse channel, the upper linkage component has a strip-shaped avoidance hole, and the adapter hole and the collapse channel are both exposed in the strip-shaped avoidance hole. The present invention provides the beneficial effect of a seat being able to instantaneously restore from a zero-gravity mode to a normal seated mode when a vehicle collision occurs, thereby improving the safety of the seat.
