Abstract: A retractable cargo restraint assembly including a housing which contains a retracting mechanism. A belt is maintained in a retracted state within the housing. The retracting mechanism controls the withdrawal and retraction of the belt. A housing connector is attached to the housing which allows the restraint assembly to be selectively connected and disconnected to an E-track. The end of the belt includes a belt connector such that the belt is connectable and disconnectable to an E-track. The restraint assembly is self-contained and portable such that a user can move the assembly and anchor the housing to a desired E-track slot. Cargo or other objects can then be restrained with the belt and secured. The restraint assembly is convenient and versatile due to its non-permanent mounting structure.
