Patent attributes
A manual gas inflator incorporating a cylinder status indication mechanism that is independent from the cylinder piercer. Prior to detonation, an indicator post abuts a sensor protrusion which positions a green surface of the indicator within the inflator window to indicate that the attached cartridge is ready for use. The jerking of a lanyard assembly causes the piercer to break the cylinder seal to allow gas to escape out of the cylinder and into a manifold secured to the inflator and also causes the indicator post to break the sensor protrusion from the cylinder. As the protrusion is broken, a second red surface of the indicator is viewable through the inflator window to indicate that the cylinder has been used and unavailable for inflation purposes.
