Abstract: A tonneau cover employs a plurality of independently operable panels that extend across the truck bed and are arranged so that the tailgate can be moved between open and closed positions regardless of the positions of the panels. Latch assemblies employ an initiator such that when operated to unlatch the panel, the initiator encourages movement of the panel to an ajar position. The panels are connected by a hinge assembly that includes a biased prop that automatically engages to hold the panel in an open position. There are two different pairs of mounting assemblies wherein a first pair includes two latching surfaces and one mounting location and the other pair includes one latching surface and two mounting locations. A two-way operable seal is employed between adjacent panels to seal the panels regardless of the sequence in which the two adjacent panels are closed.
