ABSTRACT:
A safety-belt retractor for use in vehicles comprising a take-up mechanism for taking up a safety-belt, and a locking mechanism for which is used to prevent pulling-out of the safety-belt. A clutch mechanism acts, in the running condition of the vehicle, to render the locking mechanism inactive, while, in an emergency condition of the vehicle, it activates the locking mechanism. An emergency detector provided with an inertia disk enables the clutch mechanism to connect with the locking mechanism in response to the action of the inertia disk in the emergency condition.
