US Patent 11958346 Tonneau cover with ramp system

A tonneau cover for a vehicle has a topside and an underside. The tonneau cover also includes a rail system attached to the underside. The tonneau cover also includes a ramp system. The ramp system is slidably engaged with the rail system and is configured to slide out from the underside along the rail system such that a rear end of the ramp system engages a ground surface to create a rampway between the topside and the ground surface. The ramp system can be used to load large cargo onto the topside of the tonneau cover. The ramp system is also removable from the rail system and attachable to an end of a truck bed of the vehicle such that the ramp system can be used to load cargo into the truck bed.
