A laminated safety glass pane having a predetermined breaking location and an impact point is described which contains at least two toughened glass panes and an intermediate layer, wherein predetermined breaking lines (=the predetermined breaking location), which are formed by discontinuities in the intermediate layer, are present in order to create an emergency exit and the intermediate layer is embodied in one location (for example on one side) of the laminated safety glass such as to be flexible and not able to be broken through, such that when the predetermined breaking lines are broken through, an emergency exit flap is formed which is connected to the remainder of the pane in tear-resistant manner and in a manner pivotable therewith by means of a hinged joint, and wherein the laminated glass pane contains, in at least one location (at the impact point) in the intermediate layer, one or more bodies made of a material whereof the hardness is greater than that of the glass used.
