Abstract
Abstract A cover to overlie the open bed of a vehicle afterbody, the cover including a flexible sheet provided in its periphery with a plurality of openings to receive complementally located headed buttons secured about the periphery of the vehicle bed. The cover includes an elongated retainer embedded in the sheet periphery so as to extend across the sheet openings in position to underlie the button heads and thereby secure the cover in position. Use of the retainer enables greater tolerance in the proper locations of the buttons and the sheet openings for receiving them. The retainer also provides a means for attachment of handles to stretch the cover taut.
