  In this work we study the chiral phase transition as observed by an
accelerating observer taking into account the Unruh effect. We use Chiral
Perturbation Theory at leading order and the large $N$ limit ($N$ being the
number of pions) as an effective description of low-energy QCD, and the
Thermalization Theorem to compute the relevant partition function for the
accelerating observer. As a result, we obtain that chiral symmetry is restored
for uniformly accelerated observers with acceleration $a$ larger than the
critical value $a_c=4\pi f_\pi$, with $f_\pi$ being the pion decay constant.
