The invention relates to the technical field of helicopter seat design and manufacturing, and discloses a plate-type energy-absorbing crash-proof seat which comprises a seat basin and seat legs, and each seat leg is provided with a C-shaped structure groove and an anti-crash assembly. The anti-crash assembly is located in the C-shaped structure groove; the anti-crash assembly comprises an energy absorbing plate, a sliding plate and a height adjusting locking plate, and the energy absorbing plate is located between the sliding plate and the height adjusting locking plate; height adjusting locking holes are arranged in the height adjusting locking plate, the height adjusting locking plate is connected with the seat legs through the height adjusting locking holes, the energy absorption platecomprises a fixed end and a movable end, and the fixed end of the energy absorption plate is connected with the lower end of the height adjusting locking plate; the movable end of the energy absorption plate is connected with the sliding plate; and the two sides of the sliding plate are clamped with the height adjusting locking plate, and the sliding plate is connected with the seat basin throughbolts. In the invention, energy absorption is stable and controllable, a space occupied by a conventional overturning pipe or an expanding pipe type energy absorber is reduced, processing manufacturability is improved, and a manufacturing yield is increased.
