Abstract

A composite pane having at least one weak point for closing a vehicle opening, which includes at least one glass pane and at least one further pane, and an intermediate layer that cormects the at least one glass pane and the at least one further pane to one another. The glass pane is provided with one or more weak points such that, in an event of an object striking the composite pane, the glass pane breaks at the one or more weak points, but the vehicle opening still remains closed at least by deforming the intermediate layer of the composite pane.
