Abstract

Einer Drehfalle (2) einer Schlossanordnung für eine Kraftfahrzeug-Fronthaube ist ein Anschlag (6) zugeordnet, der im Normalbetrieb Schwenkbewegungen der Drehfalle (2) über ihre Raststellung (in der sie einen Schließbügel (1) arretiert) hinaus bei allen auftretenden Schließkräften verhindert: Dem Anschlag (6) sind jedoch Mittel zugeordnet, die bei einem Fußgängeraufprall eine Verlagerung des Anschlags (6) in eine Position verursachen oder zulassen, in der er die Drehfalle (2) zu diesen Schwenkbewegungen unter dem Einfluss crashbedingter Kräfte freigibt. Dadurch wird ein zusätzlicher Deformationsweg gewonnen.

Figure 00000001
A rotary latch (2) of a lock arrangement for a motor vehicle front hood is assigned a stop (6) which, during normal operation, prevents the rotary latch (2) from swiveling beyond its locking position (in which it locks a striker (1)) with all closing forces that occur: However, the stop (6) is assigned means which, in the event of a pedestrian impact, cause or allow the stop (6) to be shifted into a position in which it releases the catch (2) for these pivoting movements under the influence of crash-induced forces. This creates an additional path of deformation.
