Title: Winding-up device with automatic lock for safety belt

Abstract: A winding-up device for a safety belt, in which a spool to which one end of the belt is connected is journaled in a housing with a spring biasing the spool in take-up direction. The belt can be freely drawn outwardly from the housing up to a limit acceleration. When a limit acceleration is reached, an inertia device interposed between the spool and the housing engages and prevents further rotation of the spool in the housing in pay-out direction.
