  We investigate parity-violating electroweak asymmetries in the elastic
scattering of polarized electrons off protons within the framework of the
chiral quark-soliton model ($\chi$QSM). We use as input the former results of
the electromagnetic and strange form factors and newly calculated SU(3)
axial-vector form factors, all evaluated with the same set of four parameters
adjusted several years ago to general mesonic and baryonic properties. Based on
this scheme, which yields positive electric and magnetic strange form factors
with a $\mu_s=(0.08-0.13)\mu_N$, we determine the parity-violating asymmetries
of elastic polarized electron-proton scattering. The results are in a good
agreement with the data of the A4, HAPPEX, and SAMPLE experiments and reproduce
the full $Q^2$-range of the G0-data. We also predict the parity-violating
asymmetries for the backward G0 experiment.
