Abstract

Safety belt roll-up device with a release mechanism which in case of danger activates a control disk and locking means which block the belt shaft. A cam having an actuating dog for actuating the locking means is associated coaxially with the control disk and rotatable relative thereto. A spring holds the dog in a predetermined starting position relative to the control disk, which spring can be deflected resiliently relative to the control disk in opposite directions of rotation. Because of its ability to be deflected in oppsite directions, a single type roll-up device will serve where previously right and left devices are needed.
