Abstract

An inertia-resistant preventer mechanism is provided for use in a firearm safety enhancement system to reliably and selectably prevent or to unblock a firing mechanism of a firearm. The inertia-resistant preventer mechanism includes a first solenoid having a moveable blocking rod with a first actuation response speed. The blocking rod is normally interposed in the firearm to prevent activation of the firing mechanism and is selectably activated to unblock the firing mechanism. A second solenoid is also included, having a second blocking rod with a second actuation response speed equal to or faster than the response speed of the first solenoid. The second blocking rod of the second solenoid is normally interposed at an angle to the first solenoid to block the first blocking rod of the first solenoid against accidental unblocking caused by inertia and relative movement of the firearm. The second solenoid is selectably activated to unblock the first rod of the first solenoid substantially simultaneously with, or prior to, actuation of the first blocking rod to unblock the firing mechanism of the firearm.
