There's no requirement that bumpers cover your frame... however, bumpers " must attach to the FRAME PERIMETER of the ROBOT with a rigid fastening system to form a tight, robust connection to the main structure/frame (e.g. not attached with hook-and-loop or tie-wraps). The attachment system must be designed to withstand vigorous game play." It is in your best interest to ensure there is sufficient support behind the bumpers that they will not come off - mounting them with some 1" angle where the only support behind the bumper is that 1/2" worth of frame would probably not be a robust connection - one good hit near the top of the bumper and it would bend/break off.
