Vehicle cargo system with rail and clamp

Various embodiments described herein relate to cargo systems for vehicles. A cargo system includes a rail stowable in a rail channel extending between a first and second side of a floor. The rail defines a rail body extending, at least partially, between the first side and the second side substantially parallel to the floor. The rail also defines rail legs rotatably connected to the floor. The rail further defines an aperture opening along a direction of the rail legs. The cargo system further includes a clamp. The clamp includes a clamp body configured for installation to the aperture. The clamp also includes a clamp arm extending from the clamp body in a direction along the rail. The clamp further includes a ratchet system that fastens the clamp body to the rail to secure a cargo item between the clamp arm and the rail.
