A cot fastening system for fastening a cot to an emergency vehicle includes a frame configured for mounting to the floor of an emergency vehicle, which has a longitudinal axis and a cot loading direction along the longitudinal axis. The system includes a first restraint assembly for coupling to a first cot attachment of the cot, which is mounted to the frame. The system further includes a second restraint assembly for coupling to a second cot attachment, which is also mounted to the frame. The system further includes a spring, such as a coil spring, for biasing the cot in a direction opposed from the loading direction of the frame to thereby apply a pre-load on at least one of said restraint assemblies.
