4. A roll-bar system for motor vehicles with a roof, which can be extended and retracted in motorized fashion by means of a roof displacement mechanism, consisting of a roll-bar body that is associated with each seat and does not comprise a sensor-controlled crash drive, which 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, wherein 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, wherein the drive for both the raising and the resetting is formed by a Bowden cable coupled to the roof displacement mechanism.
