The aim of the solution is to design a control sensor for safety belt retractor locks, in order to increase its threshold sensitivity as regards acceleration size and bank.This is achieved by the fact that the contact surface of the finger of the control lever is shaped as a circle with a radius (r)<IMAGE>in the perpendicular section, which is made in relation to the rotation axis of the control lever. The centre of the circle lies on the normal line in the contact point, which forms an angle<IMAGE>in the basic position with the line made up by the centres of the rotation of the control lever and lock.<IMAGE>
