  We consider several classes of noncommutative inflationary models within an
extended version of patch cosmological braneworlds, starting from a maximally
invariant generalization of the action for scalar and tensor perturbations to a
noncommutative brane embedded in a commutative bulk. Slow-roll expressions and
consistency relations for the cosmological observables are provided, both in
the UV and IR region of the spectrum; the inflaton field is assumed to be
either an ordinary scalar field or a Born-Infeld tachyon. The effects of
noncommutativity are then analyzed in a number of ways and energy regimes.
