Vehicle rollover protection system with a roll bar, whose top piece is rounded in a U-shape. Such top pieces are typically tubular and are made from pipe bending parts. In order to achieve a three-dimensional contour of the top piece with irregular cross section of its profile, the invention calls for at least the tubular top piece consisting of at least two axially divided partially tubular shells of sheet metal, joined to each other and having different geometrical shapes according to a nominal contour.

Rollover protection sysem for motor vehicles with predetermined deformation point

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 ( ).

Rollover protection system for motor vehicles

A roll bar protection system for motor vehicles comprising an outer box profile forming a case for the components of the roll bar protection system, being mounted firmly on the vehicle, an inner box profile, able to move in the outer box profile via guide elements which is designed as a roll bar and accommodates a fast drive for its extension into the upper end protection position in event of danger, and a drive arrangement for a continuous movement of the inner box profile, consisting of an electric motor/gearing arrangement with a threaded spindle of predetermined length, as well as a tie-bar which can be moved in the outer box profile, having a nut for engagement with the threaded spindle, and which is detachably connected to the inner box profile.

Roll bar protection system for motor vehicles

The invention addresses a rollover protection apparatus for motor vehicles with a protection system assigned to each vehicle seat. The invention provides that the profile unit is designed in the form of a box profile rigidified against bending with guide elements on the narrow sides of the profile elements and one single spring drive mechanism disposed centrally in the profile bar unit and with a pawl/ratchet mechanism mounted parallel to the bar width in a curved projection of the profile bar unit. These measures create a rollover protection apparatus that comprises only a few parts, is simple to manufacture and the depth of which can be kept very shallow.

Rollover protection apparatus

Roll bar equipment with inner guide and outer guide

A convertible motor vehicle is provided with two rollover bars which can be swivelled out of a lowered inoperative position into an upwardly directed supporting position and back around a swivel axis fixed at the vehicle and extending essentially in the longitudinal direction of the vehicle. The rollover protection system can be integrated into conventional vehicle concepts in a particularly space-saving and advantageous manner and reduces the risk of injury in the case of a fast, sensor-controlling swinging-up of the rollover bars.

Motor vehicle having a rollover bar

Rollover protection for occupants of a convertible motor vehicle is formed by two rollover bars which are disposed on a base plate and can be swivelled around swivel axes extending approximately in the longitudinal direction of the vehicle, approximately in the plane of the base plate. At the base plate which is installed largely in the transverse direction of the vehicle and approximately perpendicularly to the longitudinal direction, control elements for the swivelling of the rollover bars, as well as the triggering mechanisms and the locking devices for the extended rollover bars, are disposed. The rollover protection system can be pre-assembled easily, and the adjustability of all driving and locking elements is good. As a result of the flat construction, the system requires little installation space and permits a favorable moving direction of the rollover bars during the extending operation.
