Abstract: An attachment system attaches a structure or tonneau cover to a truck bed with side walls having stake pockets. Fastening plates are pivotally coupled to the structure or the belt rails of the tonneau cover. The plates pivotal between a first orientation in which the plates align with the stake pockets to pass therethrough, and a second orientation in which the plates rotate with respect to the first orientation to abut the stake pockets and secure the structure to the side walls of the truck bed. Tensioners can be coupled to the structure, and engage the fastening plates, to draw the fastening plates towards the structure. A cover can be removably attached to the belt rails to cover the truck bed.

Abstract: An improved tonneau cover clamp includes an inner clamp section for engaging a pickup truck bed sidewall, an outer clamp section configured to hold a tonneau cover rail to the sidewall, and a cam handle section for selectively attaching the inner clamp section to the outer clamp section so as to provide a clamping force on the sidewall. The cam handle section is configured to engage one or both of the other two sections in such a manner as to facilitate adjustment between the two sections to adjust to top flanges of sidewalls having different thicknesses, thereby enabling a single clamp to be used with a variety of different truck brands and models.

Abstract: A seat cover which fits the contour of a seat having a headrest. The cover includes a flexible headrest pocket which can be folded inwardly into the rest of the cover in order to fit the contour of a seat not having a headrest.

The seat cover fastening system includes a flexible sheet of material joined to the side and top edges of the front panel to extend about the sides and over the top of the seat back portion to the rear thereof, where the sheet of material terminates in a rear edge at the rear of the seat back portion. The rear edge is formed generally in the shape of an inverted U, and includes a channel extending along a substantial portion of the edge for receiving and holding a drawstring. A drawstring is disposed in the channel so that the ends thereof extend out respective ends of the channel.

Abstract: A dual-tongue seat cover fixture for use with a one-piece vehicle seat cover having a seat cover portion and a back cover portion for placement respectively over the seat cushion and separate seat back of a vehicle seat in which a transverse section of the cover lies adjacent the crevice between the seat cushion and the seat back. The fixture includes a sheet of flexible material joined along a midline to the transverse section of the cover, where the midline divides the sheet into first and second sections which extend throuch the crevice when the cover is installed on the vehicle seat. Loops, grommets, or other fastening elements are formed on the edges of the first and second sections opposite the midline for joining the first section to the seat cover portion and the second section to the back cover portion.
