1. Take-up device for safety belts, in particular in motor vehicles, having a mechanism for the automatic blocking of a belt take-up shaft (11) in cases of accelerations on the belt strap (12) and/or device mount exceeding a limited value, including a ratchet member (16) being excentrically pivot-mounted on the belt take-up shaft (11) and being radially pivotable for interlocking via at least one ratchet tooth (37) with a detent elements (32) fixed to the housing, the ratchet member (16) in his blocking position interacting with a shoulder (20) of the belt take-up shaft (11) protruding into the plane of the ratchet member (16), characterised in that the ratchet member (16) has at least one predetermined breaking point (40a, 46) and the belt take-up shaft (11) and/or its bearing (17) is designed to be partially deformable for mechanical loads in the range of resistance limit of the predetermined breaking point (40a, 46) on the ratchet member (16). |
