INTEGRATED PULLOUT STEP SYSTEM FOR TOP BUNK INGRESS/EGRESS

摘要

A truck (136) has a sleeper cab (138) in which a bunk (140) is elevated from a floor (72) of the cab. A cabinet (110) is adjacent an end of the bunk. A track (146, 148) runs on the cab floor from inside the cabinet to outside the cabinet. A set of stairs (42; 242) are movable along the track from a non-deployed position inside the cabinet to a deployed position that allows a person to ascend and descend the stairs for climbing up into and climbing down from the bunk. A releasable locking system (150) locks the stairs in the deployed and non- deployed positions. A handle (158) can be pulled to unlock the stairs from non-deployed position and move them to deployed position. The handle can be pushed to unlock the stairs from deployed position and move them to non-deployed position.
