Flame attenuator for poke-through constructions

摘要

A flame attenuator for poke-through constructions. The device is formed from a plurality of overlapping segments of metal screen firmly attached to a base frame and forming an inverted funnel-like structure with each of the segments converging loosely at the top of the inverted funnel. In application, the transmission shifter lever penetrates the smaller, upper hole thus formed, and in spite of being moved in horizontal arcs, maintains contact with the overlapping screen segments. Since there are a variety of boot geometries (circular based, oval based, and rectangular based) the flame attenuator base frame is provided in multiple shapes to accommodate the different boot configurations. The attenuator is located inside the shifter boot, and is manufactured either integrally to the boot, or as an add-on item. The flame attenuator protects the boot from rapid burn-through in the event of an engine fire.
