  • Patent number: 8104821
    Abstract: The invention provides a new-style tonneau cover, wherein comprises a cover plate body matching the rear truck bed. The cover plate body is a three-layer structure, comprising an outer layer, an intermediate layer and an inner layer from the exterior to the interior. The outer layer is made of polyurethane foam mixed with glass fiber; the intermediate layer is made of polyurethane foam and the inner layer is made of resin; the density of polyurethane foam in the intermediate layer is lower than that in the outer layer; polyurethane foam is light in weight and high in specific strength. In this invention, the cover plate body is made of three different layers so that the cover is light in weight and high in strength, taking up less room of the rear truck bed, better for free opening and closing operation.

  • Patent number: 7878572
    Abstract: The invention belongs to the field of automobile parts, in particular, to a tonneau cover installed on the notchback (pickup) for covering and closing the rear truck bed. The tonneau covers of current vehicles are either too thick or heavy so it influences the flexibility of opening and closing and its requirements to the actuating mechanism are high; its thickness is large; and it occupies more of the already limited room of rear truck bed. This invention provides a truck bed back cover which occupies less rear truck bed room and is strong in strength, flexible in opening and closing and excellent in operating performance. It consists of the cover plate body which matches with the rear truck bed and is made of base materials. The base material is glass fiber reinforced polyurethane. The cover plate body is provided with an integral structure framework. The framework makes the cover plate body form protruding arises on the surface of the side facing to the truck bed.
