摘要

The roll bar system (1) for a convertible automobile (2), to protect the occupants on rolling over, has a detector to register a rolling motion, coupled to a control for the actuators to trigger the components of an active safety system. The upper ends (E) of the A-pillars (4) carrying the windscreen can be coupled to the telescopic supports (3) extended by the actuators, to link the upper ends of the A-pillars with the side doors (5) of the automobile to protect the vehicle occupants if it rolls over. At least one detector monitors the zone between the start position of the supports and the position where they are locked to the A-pillars, linked to the control unit to activate the actuators. In the start position, the supports are positioned in the doors and the rear side structure.
