In index theory of families of closed manifolds the exterior differential of the eta-form describes the difference between the analytic and the topological index of a Dirac operator. Under the assumption that the horizontal distribution is integrable the question in my diploma thesis is if the eta-form is closed and defines a cohomology class in de Rham cohomology. At the end I'll look at the special case of a bundle of tori.
