A door opening system with a deceleration mechanism may be adapted to control an opening of a door module that includes a door panel and a door frame. Deceleration mechanism may include strap that connects door panel with door frame, spool, and spool. Spool may receive one end of strap, is biased to roll up a first portion of strap, and adapted to perform a first unwinding of the first portion of strap. Spool may receive a second end of strap, is biased to roll up a second portion of strap, and adapted to perform a second unwinding of the second portion of strap from spool. Spool may include a braking apparatus that is adapted to decelerate the second unwinding when a velocity of the second unwinding is above a predetermined threshold.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, a trigger mounted rotatably to the housing, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The bolt is moveable between a first, closed position and a second open position. The trigger is moveable between a first position, in which the pin and roller are engaged with the bolt when the bolt is in its first position, and a second position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load is provided on the bolt, or manually by depressing the trigger to disengage the pin and roller from the bolt.

A pressure relief door assembly that includes a relief door arranged in an opening of a compartment, wherein the relief door has a closed position in which the opening is closed and an opened position in which the opening is open, and a locking and release mechanism that is configured to keep the relief door in the closed position if the pressure inside the compartment is below a predetermined threshold pressure and that is configured to move or allow the relief door into the opened position if the predetermined threshold pressure is reached inside the compartment. The locking and release mechanism is further configured to move or allow the relief door into the opened position if a predetermined temperature is reached inside the compartment.

Disclosed herein is a safety device for attachment at an edge of a door leaf. The safety device comprises a pressure monitor and an electromagnetic lock element. The pressure monitor is configured, in response to a force being applied to the safety device, to issue a signal.

A system for monitoring a pressure change within at least one compartment of an aircraft and operating a pyrotechnic device associated with a door latch, includes a securing mechanism arranged in an aircraft door that includes a pyrotechnic actuator and a latch bolt. The system includes the pyrotechnic actuator configured to move the latch bolt when the pyrotechnic actuator is actuated. The system also includes a pressure sensor configured to provide a pressure signal. The system also includes a controller configured to determine a pressure drop representing a decompression event. The system also includes an output driver configured to generate an output signal to actuate the pyrotechnic actuator when the controller determines the occurrence of a decompression event.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, an adjustment mechanism, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The adjustment mechanism includes a compression spring, a central cap for receiving the pin and roller therethrough, and a nut for adjusting the load on the compression spring. The bolt is moveable between a first, closed position, in which the pin and roller are engaged with the bolt, and a second open position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load, as adjusted by the adjustment mechanism, is provided on the bolt to disengage the pin and roller from the bolt.

A diaphragm latch may comprise a housing, a diaphragm disposed in the housing, a pin coupled to the diaphragm, an opening in the housing, and a pin aperture disposed in the first side, wherein the pin extends from the pin aperture. The diaphragm may be configured to move in response to a pressure being communicated through the opening, and the pin may be configured to at least one of extend or retract from the pin aperture in response to the diaphragm moving. The diaphragm latch may passively couple an inner fixed structure (IFS) to an intermediate case (IMC) during an overpressure event.

A latch having a housing and a latch mechanism located within an interior portion of the housing. The latch mechanism includes an arm, a pair of socket screws, a pair of torsion springs, each of which is connected rotatably to the arm and engages a corresponding one of the pair of socket screws, a bolt mechanism attached rotatably to the housing, and a link attached pivotally to the arm and attached to the bolt mechanism. The socket screws are utilized to adjust loads on the springs. The bolt mechanism is movable between a first position, in which the arm and the link are toggled with one another under the loads of the springs and the bolt mechanism is adapted to engage an external structure, and a second position, in which the link and the arm are untoggled with one another and the bolt mechanism is disengaged with the external structure.

A blowout latch includes a rotatable bolt that secures a first panel that is adjacent to a second panel to which the latch is affixed. The bolt is restrained by a toggle linkage that operates at one end of the bolt against a pressure-actuated spring. The linkage will release the bolt when an excessive opening force against the bolt exceeds a selected restraining force of the spring. When that condition occurs, the linkage will have deflected the spring and moved to a position where the end of the linkage bearing against spring loses it mechanical leverage with respect to the bolt. Thereafter, the bolt is free to continue rotation to a fully open position. The latch also includes a manual trigger release that disables the restraining linkage and permits free rotation of the bolt to the fully open position when this trigger is actuated.

A latch assembly for a closure panel of a vehicle, the latch assembly comprising: a mounting plate; a ratchet and pawl pivotally mounted to the mounting plate, the ratchet for retaining a mating latch component in a primary latched position in a slot of the mounting plate, the ratchet released from the primary latched position by movement of the pawl; a secondary catch coupled to the mounting plate for retaining the mating latch component in a secondary latched position after the mating latch component being released from the ratchet; an active secondary catch coupled to the mounting plate by a pivot connection, the active secondary catch for retaining the mating latch component in a travel position after said mating latch component being released from the ratchet, the travel position being further from the slot than the secondary latched position, the active secondary catch having a slot providing for translation of the pivot connection therein; a lift lever mounted to the mounting plate, the lift lever for moving the mating latch component past the secondary latched position to the travel position as the pivot connection travels along the slot; wherein actuation of the lift lever by an actuation system causes movement of the secondary catch away from the slot in order to inhibit retention of the mating latch component thereby and to deploy the active secondary catch towards the slot in a deployed position in order to facilitate retention of the mating latch component thereby.
