The invention discloses a collision buffering device of an automobile seat. Linear bearings are installed on the two sides of the upper surface of a bottom plate, the two sides of a moving plate are connected to sliding parts of the linear bearings, the two sides of the front of the moving plate are connected with the outer ends of spiral springs respectively, and the inner ends of the spiral springs are connected with the bottom plate. An insertion groove/insertion grooves is/are formed in one side/two sides of the rear of the moving plate, a locking pin/locking pins corresponding to the insertion groove/insertion grooves is/are arranged at the rear of the bottom plate, and a reset spring/reset springs is/are installed on the locking pin/locking pins. The collision buffering device has the advantages that once an automobile is severely collided, an automobile body is extruded inwards, passengers dash forward under the action of inertia to pull safety belts, buckles of the safety belts pull the fixed insertion pins inside the device out of the clamping grooves, and the seat is transformed into a moving state from a fixed state. Under the action of restoring force of the spiral springs, the moving plate drives the seat to move backwards along the linear bearings by a certain distance, the seat and the passengers move synchronously, safety spaces are made in front of the passengers, and therefore it is avoided that due to extrusion, the chests and the legs of the passengers are hurt.
