  • Patent number: 11498685
    Abstract: An armrest is disclosed that includes an armrest subframe configured to couple to an arm of the seat that includes a slot within a face of the armrest subframe configured to receive a stop pin. The armrest further includes an arm pad translatably coupled to the armrest subframe and includes a plurality of grooves formed on one edge of the armrest subframe. The arm pad further includes the stop pin that restricts the translation of the arm pad and a spring anchor. The armrest further includes a lever rotationally coupled to the armrest that includes a locking pin configured to engage one or more grooves of the plurality of grooves, and an actuating end, wherein a movement of the actuating end at least one of engages or disengages the locking pin from the one or more grooves of the plurality of grooves. The armrest further includes a biasing spring.

  • Publication number: 20220320697
    Abstract: Systems for suppressing adverse exothermic reactions in an energy storage container. One energy storage system includes a container configured to support a plurality of battery cells; a plurality of battery cells disposed inside and supported by the container; an agent supply port attached to the container; and a tube disposed inside the container and having a closed end and an open end. The open end of the tube is in fluid communication with the agent supply port. The tube comprises fusible portions which are designed to melt or soften at a temperature which is lower than the melting or softening temperature of another portion of the tube. In response to melting or softening of the fusible portions of the tube, pressurized exothermic reaction-suppressing agent is distributed inside the container via the tube.

  • Patent number: 11459109
    Abstract: An armrest is disclosed that includes an armrest frame rotationally coupled to a seat frame, an armrest subframe pivotably couple to a second end of the armrest frame, and an arm pad laterally aligned and translatably coupled to the armrest subframe. The armrest further includes a tilting mechanism configured to pivot the armrest subframe relative to the armrest frame. The armrest further includes a translation mechanism configured to translate the arm pad relative to the armrest subframe. The armrest further includes a rotation mechanism configured to rotate the armrest relative to the seat frame. At least one of the tilting mechanism, the translation mechanism, or the rotation mechanism includes a spring-loaded linkage.

  • Publication number: 20210370111
    Abstract: Described herein are zonal fire suppression systems and methods of using such systems for suppressing fires in cargo aircraft. A system is configured to individually monitor the temperature in each of multiple cargo zones in the cargo area. The system is also configured to selectively activate one or more of multiple zone distribution components to distribute a fire suppressant material, based at least on the temperature monitoring. The zonal approach to the temperature monitoring and to the fire suppressant material distribution allows reducing the fire suppressant material amount needed on the cargo aircraft, which, in turn, reduces the aircraft load. Furthermore, in some examples, the zonal approach eliminates unnecessary contact between the cargo (e.g., in the zones unaffected by fire) and the fire suppressant material. In some examples, this fire suppression involves depressurizing of the cargo area, in addition to or instead of the fire suppressant material distribution material.

  • Patent number: 10343003
    Abstract: A fire suppression system for an aircraft having a compartment, the fire suppression system including an inert gas source in selective fluid communication with the compartment and a fire suppression agent source in selective fluid communication with the compartment, wherein an inert gas from the inert gas source and a fire suppression agent from the fire suppression agent source are at least partially combined to form a fire suppression mixture.

  • Patent number: 10238901
    Abstract: A cargo-fire-suppression agent distribution system and methods are presented. A fire-warning signal indicating presence of fire in a cargo compartment onboard a class E cargo aircraft at a first altitude is received. An initial fire-suppression agent is distributed in the cargo compartment at the first altitude sufficient to suppress fire for an initial fire suppression time interval during a depressurization phase during which the class E cargo aircraft flies to a second altitude below the first altitude. A re-enforcing fire-suppression agent is distributed in the cargo compartment during a re-pressurization phase when a cabin altitude is below a predetermined cabin pressure level (PL) during which the class E cargo aircraft flies from the second altitude to a landing, after the initial fire-suppression time interval elapses. The re-enforcing fire-suppression agent distribution is maintained during a re-enforcing fire-suppression time interval.
