Patent ID: 8186486

Claim:
An inertia brake assembly, comprising: a rotor hub subassembly, wherein the rotor hub assembly includes a rotor, and at least one frictional plate attached to the rotor; and an inertia brake subassembly, wherein the inertia brake subassembly includes a first reaction plate connected to a second reaction plate, wherein rotor is disposed between the first reaction plate and the second reaction plate, wherein both of the first and second reaction plates include a radially-projecting bracket defining an axial opening, and a sleeve axially inserted through the axial opening of the radially-projecting bracket of one of the first and second reaction plates, wherein the sleeve includes a radially-projecting lip, wherein the radially-projecting lip is disposed between the first reaction plate and the second reaction plate, wherein the rotor is defined by a first thickness, wherein the radially-projecting lip is defined by a second thickness, wherein the at least one frictional plate is defined by a third thickness, wherein the second thickness is about equal to but greater than the first thickness, wherein the second thickness is about equal to but less than the third thickness.
