Abstract: A resilient strut assembly adapted to secure an aerodynamic skirt panel to a trailer is presented, the aerodynamic skirt structure being adapted to be substantially longitudinally mounted to the trailer, the resilient strut assembly being adapted to sustain an elastic deformation when a load is applied to the resilient strut assembly when the skirt panel moves away from the configuration and to self-recover its original position when the load is removed without the deformation extending over a limit deformation. The resilient structure comprises a first resilient strut and a complementary strut limiting flexion of the skirt panel.

Abstract: A strut member to be secured to the floor structure includes a top skirt-contacting portion for the aerodynamic skirt panel to be secured thereto, a lower skirt-contacting portion for the aerodynamic skirt panel to be secured thereto distant from the top skirt-contact portion, and a strut portion connecting the top skirt-contact portion to the lower skirt-contacting portion. The strut member provides a clearance in which the skirt panel is free of contact with the strut member between the top skirt-contact portion and the lower skirt-contacting portion. The strut portion is configured to resiliently buckle between a buckled position upon the skirt panel undergoing a force exceeding a threshold value toward the strut member and an original position when no force is applied and when the skirt panel is undergoing a force that is less than the threshold value.
