Abstract
A safety interlock for a vehicle driven through a transmission by an internal combustion engine that has a magneto ignition system and a seat occupied by a driver. The interlock is electrically connected to the ignition and to safety switches, one that is opened when the transmission to a traction drive is engaged and another that is closed when the seat is occupied. The interlock circuit disables the ignition if the engine is not running and the transmission is engaged so the engine cannot be started under unsafe conditions. The engine is also disabled if, after it is running, the seat becomes unoccupied while the transmission is engaged. However, the interlock allows the engine to be started with the seat occupied or not, as long as the transmission is disengaged. One or more safety switches associated with mechanisms driven by the engine can be connected in series with the transmission-operated safety switch to control operation in the same manner.
