Abstract: A retractable aerodynamic panel for an automotive truck cargo bed comprises a first support rail adapted to be mounted onto a top edge of a first side wall of an automotive truck bed and a second support rail adapted to be mounted onto a top edge of a second side wall of an automotive truck cargo bed, a panel adapted to be mounted onto a tailgate of the automotive truck cargo bed, the panel adapted to extend between a retracted position, wherein the automotive truck cargo bed is substantially open, and a deployed position, wherein the panel extends outward from the tailgate across a portion of the automotive truck cargo bed between the top edges of the first and second side walls, the panel supported between side walls within the support rails, and an actuator adapted to selectively extend the panel between the retracted and deployed positions.

Abstract: A latching device for engaging a striker includes a rotatable locking plate configured for receiving the striker. A linkage is configured to counterbalance the locking plate in a first, latched position. An active material actuator is interconnected with the linkage such that activating the active material actuator moves the linkage out of counterbalance with the locking plate and into a second, unlatched position.
