  The Bumblebee Model of spontaneous Lorentz symmetry breaking is explored in a
cosmological context, considering a single non-zero time component for the
vector field. The relevant dynamic equations for the evolution of the Universe
are derived and its properties and physical significance studied. We conclude
that a late-time de Sitter expansion of the Universe can be replicated, and
attempt to constrain the parameter of the potential driving the spontaneous
symmetry breaking.
