1. A system for restraining a cargo container in a cabin of an aircraft, the system comprising:
a guide rail spanning a length of a seat track and being configured to releasably couple to the seat track at one or more locations on a bottom surface of the guide rail, the guide rail comprising at least one stud on the bottom surface of the guide rail for coupling to the seat track, the guide rail configured to engage with the cargo container, the guide rail having opposing side surfaces defining a guide rail channel;
a plurality of rollers coupled to the guide rail, wherein the plurality of rollers of the guide rail are at least partly fitted within the guide rail channel, a top portion of a rolling surface of each of the rollers is raised relative to the top surface of the guide rail to engage the container when the container engages with the guide rail, wherein the top portion of the rolling surface is positioned on a side of the guide rail opposite the stud; and a wheel track defining at least one wheel path, each wheel path comprising:
a first wheel ramp for receiving a wheel of the cargo container, the first wheel ramp configured to engage the wheel and elevate the cargo container when the wheel rolls up a slope of the first wheel ramp;
a second wheel ramp spaced apart from the first ramp, the second wheel ramp configured to lower the cargo container onto the guide rail when the wheel rolls down the slope of the second wheel ramp; and
a wheel track channel defined by the wheel track for restricting movement of the wheel outside of the at least one wheel paths, the channel communicating with the first wheel ramp and the second wheel ramp, wherein when the wheel track is positioned in the cabin of the aircraft, the wheel track channel is positioned at an angle with respect to the guide rail.
