The invention relates to a roll-bar system for vehicles comprising a roof, which can be retracted and raised in a motor-driven manner by means of a roof-displacement mechanism. Said system consists of a roll-bar body that is associated with each seat and does not comprise a sensor-controlled crash drive. The body can be forcibly displaced autonomously, in conjunction with the roof-displacement mechanism, between a first rigid position, when the roof is closed, and a second raised, rigid position, when the roof is open. The aim of the invention is to raise said rigid roll-bar system into the respective rigid positions in a kinematically simple, forcibly guided manner. To achieve this, the roll-bar body is mounted and guided in a cassette-type housing that is fixed to the vehicle and said body is associated with a drive, which is coupled to the roof-displacement mechanism and used to displace said body vertically in the housing and with a position-dependent forcibly guided locking device, which is used to lock said body in the raised position.
