Abstract: An energy absorber includes a first split section, a first single strand section, a second split section, a second single strand section, and a third split section which are connected in sequence. The first split section and the third split section each include at least two sub-woven belts. The at least two sub-woven belts are separated from each other. At least one of the at least two sub-woven belts is capable of being stretched and contracted under an action of an external force. The first split section, the first single strand section, the second split section, the second single strand section and the third split section are integrally woven.
