Abstract

The invention relates to a safety belt apparatus comprising a belt roller (12) which is preferably resiliently subjected to a bias force in the belt wind-up direction, which carries a more or less rolled up belt (11) and which can be blocked against a further drawing out by a tooth blocking mechanism which can be triggered by an acceleration sensor (13) preferably having a movable mass, such as a ball (35), which has a position control gear (18) which is preferably coaxial with the belt roller (12) and which is rotationally fixedly connected to an auxiliary blocking tooth crown (14) which is directly stressed by an auxiliary pawl (17) of the acceleration sensor (13) and which drives a main pawl (16) which is rotationally fixedly coupled to the belt roller (12) into a main blocking tooth crown (15) which is fixed to the housing when stopped by the auxiliary pawl (17) and in the presence of a drawing out force at the belt (11) whereupon the further drawing out of the belt is stopped. The invention consists in that the auxiliary blocking tooth crown (14) is designed as an inner tooth crown at a secondary gear (19) which is coupled in a rotationally fixed manner to, in particular which meshes with, the position control gear (18), preferably coaxially; and in that the acceleration sensor (13) is arranged in the interior of the auxiliary inner blocking tooth crown (14) so as to be displaceable at least about an axis (20, 21) in such a manner that with a corresponding constructional design of the auxiliary pawl (17) the latter can come into blocking engagement with the inner tooth crown (14) in any installation position of the acceleration sensor (13).
