US Patent 11535483 Reduced sized wearable retractable

A pawl-less retractable comprises an inner frame with a drum-sperrad assembly mounted to the inner frame between side members of the frame to rotate relative to the frame and a stop cap which, during a fall, engages said drum-sperrad assembly to prevent further rotation of said drum. The inner frame can be pivotally mounted to the stop cap such that the inner frame and the drum-sperrad assembly pivot relative to the step cap, or the stop cap can pivot relative to the drum-sperrad assembly. The stop cap comprises a central body, a leading wing extending from a first side of the central body and a trailing wing extending from a second side of the central body opposite said first side. In use, the drum-sperrad assembly and the stop cap pivot relative to each other between an unlocked position in which the teeth of the sperrad are inside of an engagement zone circle and a locked position in which the teeth are outside of the engagement zone circle.
