  • Truck bed cover lock
    Patent number: 6702358
    Abstract: A truck bed cover lock having two locking units positioned to interact with the existing latch locks present on most bed covers. Each locking unit contains an actuator which is electronically connected to the existing or added on electric locks in a truck. When the door locks in the truck are electrically locked the actuators extend a sliding latch into position behind the latch locks present on the bed cover thereby preventing the bed cover from being opened. Conversely, when the truck locks are electrically unlocked the actuators retract the sliding locks and permit the bed cover to be opened. The invention may be an OEM (factory) item, or an aftermarket item.
