US Patent 11772714 Extendable cargo bed side walls having cargo bed access openings

A cargo bed system includes a side wall assembly of a cargo bed. The side wall assembly is configured to transition back-and-forth between a standard wall position and an extended wall position. The side wall assembly includes an extendable wall section and a fixed side wall section. The extendable wall section extends and retracts relative to the fixed side wall section when the side wall assembly transitions back-and-forth between the standard wall position and the extended wall position. The side wall assembly in the extended wall position provides a cargo bed access opening within the side wall assembly.
