Vehicle cargo system with rail and clamp

A system, comprising:

• a hollow rail stowable in a rail channel extending between a first and second side of a floor, the rail defining:
• a rail body extending, at least partially, between the first side and the second side substantially parallel to the floor,
• rail legs rotatably connected to the floor,
• an aperture opening along a direction of the rail legs,
• a plate within the rail;
• and
• a pawl connected to the plate by a spring and extending into the aperture;
• and
• a clamp including a clamp body configured for installation to the aperture, a clamp arm extending from the clamp body in a direction along the rail, and a ratchet system that fastens the clamp body to the rail to secure a cargo item between the clamp arm and the rail, the ratchet system including ratchet teeth defined by the clamp body and engaging the pawl to secure the clamp body to the rail and position the clamp at a height in which the clamp arms applies a force to the cargo item in a direction toward the rail to secure the cargo item to the rail.
