Occupant safety system with electric retractor changeover device has final control element controlled by externally triggered signal for actuating changeover that blocks belt shaft in child seat mode

摘要

The system has a control system for controlling a belt spooler locking device with a belt shaft and a device for changing over between acceleration-dependent ELR operation and ALR operation, especially for securing child seats. An electrical final control element controlled by an externally triggered electric signal provided for actuating the changeover blocks the belt shaft in ALR mode and enables the control and locking system in ELR mode. The system has a control system sensitive to the vehicle and/or safety belt for controlling a locking device for the self-locking belt spooler with a belt shaft and a changeover device for changing over between acceleration-dependent ELR operation and ALR operation, especially for securing child seats with the belt spooler. An electrical final control element (13) controlled by an externally triggered electric signal provided for actuating the changeover blocks the belt shaft in ALR mode and enables the control and locking system in ELR mode.
