Abstract
The invention relates to a locking device for safety belts of the type having a switch assembly where the belt is passed downwardly over a locking bar for locking and where the locking bar, on activation of a releaser is tipped upwardly. The locking device is connected to an electric signal circuit which gives a warning signal if the safety belt is not employed. The electric connection for the signal circuit is arranged on the locking device. The circuit is connected when the locking bar is open, and broken when the locking bar is pressed down. The locking bar forms in the downward position an electrically conductive connection to a contact point, and the connection is broken when the safety belt is placed around the locking bar.
