Connection of auxiliary frame for better passenger protection in case of collision, has detachable connecting place formed as locking mechanism

摘要

Connection of auxiliary frame (12) has detachable connecting place (16) formed as locking mechanism. The swiveling locking element (18) is carried from the plastic deformable torsion bar (17) fixed in the support structure (10) during which bolt (22) consisting of locking element is fixed in locking position at auxiliary frame. The locking mechanism releases the bolt and thus the auxiliary frame for a relative motion relating to the support structure starting from a pre-determined torsion angle of the torsion bar according to a defined force level.
