US Patent 12089725 Collapsible backpack system

A frame for a collapsible and deployable backpack can include a plurality of struts and straps configured for carrying luggage. The struts can be attachable to form a backpack frame. The straps can be attachable to the struts for wearability. The luggage can be in the form of two or more independent pieces of luggage attachable to the frame, for example, two or more pannier bags. The frame can include upright struts bent into a bowed configuration. The bowed struts can be oriented in a splayed apart configuration to provide racking resistance. In a collapsed configuration, the backpack can have an overall width that is less than a pedal width of a bicycle, and optionally less than a width of a suspension portion of a bicycle.
