<p>A safety system stops continuation of motion of a powered vehicle such as a boat or motorized land vehicle when a person falls off the craft. In one embodiment, the system comprises a wireless transmitter carried by the person, a receiver-controller (24); an actuator (50) and associated latch key (40), both being part of a hold-release assembly (60); and a spring loaded kill switch (30). When the person falls off the vehicle, a change in wireless signal causes the actuator (50) to disengage the latch key (40) from the kill switch (30), thus stopping the engine or other propulsive means. In other vehicles, a power switch is rotated, or a sail is disconnected, by an actuator. One kind of actuator (50) stores mechanical energy which is manually input by compressing the spring. The system is useful for retrofitting onto vehicles, especially boats, which have kill switches which are actuated by a lanyard running to the operator.</p> |
