The invention relates to an exoskeleton in which a pelvis structure (301) comprises a central pelvis segment (401) arranged such as to be attached to the pelvis (110) of a person wearing the exoskeleton. A peripheral pelvis segment (402) is connected to a leg structure (302). Another peripheral pelvis segment (403) is connected to another leg structure (303).
