A bodywork structure for a passenger vehicle includes a bodywork shell construction with two longitudinal girders and a flexible crossmember device attached to the two longitudinal girders. The flexible crossmember device has a first flexible crossmember and two energy absorption elements where the two energy absorption elements are respectively fixed to the two longitudinal girders and the first flexible crossmember is connected to the two longitudinal girders via the two energy absorption elements. A support framework is disposed between the two longitudinal girders and has a second flexible crossmember that is at least indirectly connected to the two longitudinal girders and is convexly curved in a direction of the first flexible crossmember. The support framework has a load divider disposed between the first flexible crossmember and the second flexible crossmember in the longitudinal direction of the passenger vehicle and extending in the transverse direction of the passenger vehicle.

A crash impact attenuator is adapted for deployment on a vehicle, and includes a cartridge portion having at least one energy absorbing module, as well as a backup system having a backup frame, which is adapted to attach the cartridge portion to the vehicle. The backup system includes an actuator configured to pivot the cartridge portion between a deployed orientation and a stored orientation about a pivot axis disposed on a lower half of the backup system. The backup system further includes a lockout frame member having a contact surface on one end thereof, the lockout frame member being actuatable between a deployed orientation wherein the contact surface engages a portion of the backup frame to support the backup frame against vehicular impact forces and a stowed orientation wherein the contact surface is not engaged with the backup frame.
