Abstract

A rollover protection system for motor vehicles with a roll bar, which can be moved by a drive unit from a position of rest to a protection position, is secured in the protection position by a locking device and prevented from retracting, and is fixed in the position of rest by a holding device, wherein the holding device has a movably arranged catch element which can be disengaged abruptly by a pyrotechnic actuator. For such cases in which the catch element can move beyond the release point and there is a danger of a rebounding, because a path-limiting stop is present, a structural part is provided that prevents a return movement of the catch element into the holding position.
