Aircraft Ceiling Resettable Decompression Roller Assembly

A resettable decompression system for relieving pressure in an aircraft passenger cabin during a decompression event, comprising:

• a panel separating a crown space of an aircraft from the aircraft passenger cabin;
• a slip fitting attached to the panel, the slip fitting comprising a slot;
• a resettable decompression retainer attached to a structure of the aircraft, the resettable decompression retainer comprising:
• a base pivotally connected to a swing arm, wherein the swing arm has a bias that biases the swing arm relative to the base;
• the swing arm having a closed position, an over-center position, and an open position relative to the base, wherein the bias forces the swing arm to the closed position when the swing arm is between the closed position and the over-center position and the bias forces the swing arm to the open position when the swing arm is between the over-center position and the open position;
• and
• a roller formed in the swing arm and slidably engaged with the slot.

A method for relieving pressure from a passenger cabin of an aircraft during a decompression event, the method comprising:

• attaching a resettable decompression retainer to a structure of the aircraft, the resettable decompression retainer comprising a base configured to be attached to the structure of the aircraft and a swing arm pivotably connected to the base, wherein the swing arm has a bias relative to the base;
• attaching a slip fitting to a panel of the aircraft, the slip fitting comprising a slot, wherein the panel separates the passenger cabin from a crown space of the aircraft and wherein the swing arm is slidably engaged with the slot;
• and
• in response to a force applied to the resettable decompression retainer, rotating the swing arm relative to the base against the bias to an open position as the swing arm moves through the slot if the force applied to the resettable decompression retainer is greater than the bias.
