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 a roof-displacement mechanism. The 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 the 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 the body is associated with a drive, which is coupled to the roof-displacement mechanism and used to displace the body vertically in the housing and with a position-dependent forcibly guided locking device, which is used to lock the body in the raised position.

Roll-bar system for motor vehicles comprising a retractable roof

Systems of this kind typically are equipped with a roll bar ( ) mounted within a cassette-like housing ( ) which can be firmly attached to the vehicle and has two U-shaped lateral parts ( ) which are linked to one another at the bottom by a bottom part ( ) and at the top, by a guide block ( ). In order to ensure small assembly dimensions while at the same time offering a low-cost connection method, the invention provides a connection of the guide block ( ) to the U-shaped lateral parts ( ) in the shape of a form-fit connection ( ).
