Retightener for automatic safety belt roll-up devices with a power reservoir which can be triggered in the case of a crash and with an energy transducer which acts upon the belt shaft of the automatic winder after triggering the power reservoir, causing the automatic winder to perform a rotary retightening motion. A rotatable pulling means pulley is provided as energy transducer which can be coupled to the belt shaft. The pulling means of the pulley is in connection with the power reservoir and effects the coupling connection and a retightening motion of the belt shaft after triggering the power reservoir and after surmounting the holdback force of a holdback device, e.g. shear pins. |
