Japanese Patent JP4070383

Kind Code:

B2

Abstract:

The invention relates to a safety belt apparatus, in particular for motor vehicles, comprising a safety belt (11) which is connected on the one hand via a belt lock (12) to the vehicle body (13) and on the other hand to a belt winder (14) which is attached to the vehicle body (13), and which has a belt roller (15) which is rotatable about a transverse axis (16) and onto which the belt (11) is wound up to a greater or lesser extent, which is stressed by a spring mechanism (17) in the belt roll-up direction and is connected to a belt tautener (18) as well as to an unwind blocking apparatus (19) which blocks the further drawing out of the belt in the attempt of a rapid belt drawing out and/or in accident caused accelerations at the latest after a limited further rotation of the belt roller (15), with a coupling (20) consisting of an input part (22), an output part (24) and coupling members (25) which are active between them being placed between the belt tautener (18) and the belt roller (15), which coupling (20) is normally open and closes at the beginning of the rotation of the belt tautener (18) after a triggering in order that the belt roller (15) can be abruptly driven in the wind-up direction by the belt tautener (18). The invention consists in that the coupling (20) can be automatically disengaged when the torque which acts on the belt roller (15) in the wind-up direction exceeds the torque which is exerted by the belt tautener (18).
