It is shown within Kaluza-Klein type theories that combination of gravitation and a model of electrically weak Weinberg-Salam interactions is possible even with a six-dimensional Riemann geometry. A new mechanism is proposed for introducing non-Abelian calibrating fields in Kaluza-Klein type theories. It is shown that after dimensional reduction, the initial lagrangian - a six-dimensional scalar curve - coincides with the lagrangian of the bosonic sector of the Weinberg-Salam model along with a four-dimensional gravitational Lagrangian.
