Abstract: The invention relates to an energy absorber for a vehicle bumper assembly, comprising a thrust transmitting section (1) and a deformable section (2) which are connected to one another, the respective opposing ends thereof being connected to a bumper cross-member (3) and a longitudinal member (4) of a main structure of the vehicle. The thrust transmitting section (1) includes a thrust transmitting member (5) having an elongate configuration extending along the longitudinal axis of the vehicle. The deformable section (2) includes: deformable members (6, 8) in the form of a bridge defining stacked and joined supporting configurations (6a, 8a) to which the thrust transmitting member (5) is connected, and legs (6b) which extend from said supporting configurations (6a, 8a) substantially along the longitudinal axis of the vehicle and which are connected to the longitudinal member (4), optionally by means of a flat bar (10).
