The invention discloses a bidirectional sliding energy absorption sliding rail for an automobile seat. The bidirectional sliding energy absorption sliding rail comprises a fixing mechanism, an adjusting mechanism and an energy absorption mechanism. The fixing mechanism is connected with the adjusting mechanism; the adjusting mechanism is connected with the energy absorption mechanism; the energy absorption mechanism comprises an upper sliding rail and a first steel sheet deformation unit; an opening is formed in the first surface of the upper sliding rail; the first steel sheet deformation unit is fixedly mounted on the upper sliding rail; the first steel sheet deformation unit comprises a short-edge limiting block, an energy-absorbing steel sheet and a long-edge limiting block; the short edge limiting block and the long edge limiting block are fixedly installed on the first surface of the upper sliding rail and arranged on the two sides of an opening of the upper sliding rail correspondingly. The energy-absorbing steel sheet is arranged between the short-edge limiting block and the long-edge limiting block, and one end of the energy-absorbing steel sheet is fixedly connected with the short-edge limiting block. The bidirectional sliding energy-absorbing sliding rail can give consideration to two working conditions of front collision and tail collision, and has the advantages of being lower in structural cost, simple, reliable, better in protection effect and easy to maintain and replace.
