Regulating horological member with flexible guide provided with temperature-compensation means

A member for a horological movement including an oscillating mass, for example a balance, a flexible guide including at least two main flexible blades connecting a movable support to the oscillating mass to enable the oscillating mass to make a rotary movement about a virtual pivot, wherein the regulating member includes an elastic device for compensating for the temperature arranged so as to connect the movable support to a securing device for securing the regulating member on the horological movement, the elastic compensation device being configured to adapt its stiffness according to the temperature in order to compensate for the effect of temperature on the regulating member.
