rollbars
Overhead steel tubes
Rollbars are protective metal bars or frames installed in vehicles—especially convertibles, race cars, and off-road vehicles—to prevent the roof from crushing occupants if the vehicle rolls over.
A full cage surrounding the interior is a roll cage; rollbars typically arch behind the seats.
