Horological regulating member having a balance spring and provided with temperature- compensation means

A regulating member for a horological movement comprising an oscillating weight and a balance spring comprising a flexible strip wound about itself in a plurality of turns, the strip having a predefined rigidity to allow the oscillating weight to undergo a rotary oscillatory motion, the strip comprising an outer end,

• wherein the regulating member comprises a temperature-compensating resilient device configured to adapt the stiffness thereof as a function of temperature to compensate for the effect of temperature on the regulating member, the resilient device comprising a resilient element connecting the outer end to a first support that is stationary relative to the horological movement, as well as preloading means for applying a variable force or torque to the resilient element as a function of the temperature, and
• wherein the resilient element comprises a suspended point-shaped body and a pair of non-crossing blades connecting the suspended point-shaped body to the first stationary support.
