Driving device for a translatory movable roll bar

Abstract

Abstract The invention relates to a drive system for a roll bar which can be extended in a translatory fashion. Roll bars of this kind have until now required a crash drive for rapidly extending them and a second drive assembly as a comfort drive for slowly retracting and extending the roll bar. The object of the invention is to disclose a drive which requires only a single drive assembly whilst retaining the essential features of crash drive and comfort drive. The principle of the invention consists in inserting a transmission element, which on the one hand ensures there is sufficient speed when the roll bar is extended and on the other hand permits a translatory movement by reversing the direction of the force. Advantageous further developments are concerned with the use of a toggle joint (31) as transmission element and the use of a stop (33) in order, by means of dead-centre position of the toggle joint, to secure the roll bar in its extended position against undesired retraction. <IMAGE>
