Abstract (EN): We summarize the results of the chiral quark-soliton model (chi QSM) concerning basically all form factors necessary to interpret the present data of the parity-violating electron scattering experiments SAMPLE, HAPPEX, A4 and G0. The results particularly focus on the recently measured asymmetries and the detailed data for various combinations of G(M)(s), G(E)(s),(G) over bar (p)(A) and (G) over bar (n)(A) at Q 2 = 0.1GeV(2). The calculations yield positive strange magnetic and electric form factors and a negative axial vector one, all being rather small. The results are very close to the combined experimental world data from parity-violating electron scattering and elastic v p and vp scattering.
