Abstract: 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.

Abstract: This protective device (100) is used in a motor vehicle having a front hood (300), which covers the front of the vehicle, leads up to the front windshield and which, at the windshield, is rotatably coupled via a hinge system (200) to the body of the front of the vehicle on both sides of the vehicle. According to the state of the art, the inventive protective device consists of a hinge support (2), which is provided for indirectly coupling the hinge system (200) to the vehicle body and which is mounted in a raisable manner on the body of the front of the vehicle. The protective device also consists of an energy-storing implement, which acts upon the hinge support (2) while being provided in the form of a spring storage system (4), and consists of a sensor-controlled retaining device (11) for actively engaging with the hinge support (2) so that, in the normal state, the hinge support is held down and during a collision, can be released by sensor actuation in order to execute a limited raising movement.

Abstract: Systems of this kind typically are equipped with a roll bar (1) mounted within a cassette-like housing (7) which can be firmly attached to the vehicle and has two U-shaped lateral parts (8, 9) which are linked to one another at the bottom by a bottom part (10) and at the top, by a guide block (11). 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 (11) to the U-shaped lateral parts (8, 9) in the shape of a form-fit connection (8a, 11a).
