ABSTRACT:
A safety latched, water-activated, automatic inflator is disclosed for use in conjunction with inflatable devices such as personal flotation devices. The safety latch operates to relieve the pressure normally exerted by the actuator pin on the water soluble element during periods of nonuse such that the water soluble element will not prematurely degrade causing inadvertent and unintended actuation of the inflator. The safety latch of the invention comprises many embodiments including a removable latch lever, a pivotable latch lever, a rotary latch lever, a transverse rotary latch lever, and a push/pull latch lever. A throwable personal floatation device is disclosed which incorporates the safety latch automatic inflator of the invention.
