The invention relates to seat energy absorbers, in particular to a creeping preventing rolling type energy absorber capable of being combined with a seat main rod. The creeping preventing rolling typeenergy absorber comprises an energy absorbing pipe assembly, a sliding sleeve and a rolling base assembly. The energy absorbing pipe assembly and a movable part of a seat are connected together. Therolling base assembly is connected with a cabin and belongs to a seat fixing part. The sliding sleeve is arranged between the energy absorbing pipe assembly and the rolling base assembly. The energy absorbing pipe assembly and the rolling base assembly are connected with the seat main rod together through pan head screws. A seat leg lock is matched with a universal aviation guide rail, unlocking and locking can be achieved without tools, and the seat leg lock can adapt to complex airplane floor deformation work conditions.
