Generalizing cosmological Friedmann equations (GCFE) for homogeneous isotropic models including scalar fields and usual gravitating matter are introduced. It is shown that by certain restrictions on equation of state of gravitating matter and indefinite parameter of GCFE generic feature of inflationary cosmological models of flat, open and closed type is their regular bouncing character.16 pages, LaTeX2e, some additions are madeGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - Theorytext
