The description of space-time in a quantum theoretical framework must be considered as a fundamental problem in physics. Most attempts start with an already given classical space-time - then the quantization is done. In contrast to this the central assumption in this paper is not to start with space-time, but to derive it from some more abstract presuppositions like this is done in von Weizsaecker's "quantum theory of ur-alternatives". Mathematically the transition from a manifold with spin structure to a manifold with four real space-time coordinates has to be considered. The suggestion is made that this transition can be well described by using a tetradial formalism which appears to be the most natural connection between ur-spinors and real four-vectors.
