Abstract

Locking device for extendable safety belts, comprising a spool elastically requested to keep the belt or band of the belt rolled up and a device for locking said reel, driven by acceleration, characterized essentially by the fact that the axis of the reel is fixed a plate having a face facing and spaced from a surface parallel to it and forming part of the fixed body of the winder device, between whose face and surface is mounted loosely and sliding on the shaft a rotor provided with a peripheral toothing, susceptible of being locked in rotation by a trigger actuated by the acceleration-sensitive device, the facing faces of the rotor and the plate being provided with complementary toothing and having, on the one hand, flanks of the rotating drive of the first by the second in the sense of development of the band, and on the other hand axial cam flanks qu e tend to displace the rotor towards the fixed surface when the latter is blocked during that movement, while the facing faces of said rotor and fixed surface have teeth of axial coupling, normally separated, but capable of engaging and blocking the assembly upon occurrence. the axial displacement of the rotor.
