LUGGAGE RETENTION SYSTEM FOR A VEHICLE

Load arresting system for motor vehicle, comprising a longilinear load-arresting cross member (30) able to extend transversally across the vehicle between two lateral structures (16) of the body shell (10) of the vehicle so that it is situated behind a row of at least one seat back rest and in front of a luggage compartment (12) of the vehicle. A device (32) used for attachment and for absorbing energy by controlled deformation is formed at each of the ends of the cross member (30) for attaching the cross member laterally to said corresponding lateral structure (16) and for deforming under the effect of a determined force. This force is designed to be representative of the force induced by a load situated in the luggage compartment and tending to push against the cross member in the event of a frontal-type impact between the vehicle and an obstacle. Application to a vehicle sub assembly that partially delimits a luggage compartment.
