Abstract

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.
