ABSTRACT:
A safety belt retractor for vehicles with a locking device arranged to lock upon an acceleration of the vehicle. This acceleration is sensed by an activating means convertible between an inactive and an activated condition in which the retractor is locked by means of a pawl engaging a ratchet wheel. The activating means can be mounted in different angular positions around a pivot axis relative to the housing of the retractor. The activating means includes a transmission element for the transmission of the different conditions to the pawl. The transmission element has a guiding surface located in connection with said pivot axis. The pawl bears by means of a portion against said guiding surface, which is displaceable transversely to said pivot axis in dependence on the condition of the activating means.
