Publication number: 20230365262Abstract: In some embodiments, a cushion material is disclosed. The cushion material is configured to be 3D-printable. The cushion material includes a plurality of gyroid lattice structures configured to be 3D-printable. The plurality of gyroid lattice structures are aligned along, and with respect to, a surface of the cushion material. In some embodiments, a method for providing a cushion material that is capable of being 3D printed is disclosed. The method includes generating a design of the cushion material comprising a variable mechanical stiffness across a surface of the cushion material. The method further includes producing the cushion material via additive manufacturing based on the design. Generating the design includes generating a layout design of a plurality of tube-like shaped gyroid lattice structures of the cushion material aligned with the surface of the cushion material.Type: ApplicationFiled: August 31, 2022Publication date: November 16, 2023Inventors: Nicole Sluder Whyte, Mark B.

Patent number: 11787546Abstract: A floor mounted aircraft seat seal frame includes a frame, displacing elements connecting the frame to the posterior of the seat, and fabric tensioning elements that keep a gap covering fabric connected to the posterior surface of the seat in tension around the frame. The frame displacing elements, which may be leaf springs, coil springs, or manually adjustable element, allow the frame to conform to a wall behind the seat, regardless of the tapering of the wall.Type: GrantFiled: June 11, 2021Date of Patent: October 17, 2023Assignee: AMI Industries, Inc.Inventors: Apoorva Jayaramu, Nikhil Anthony Saldanha

Patent number: 11548643Abstract: Disclosed is a height adjustable seat pan assembly such as for use in an aircraft cabin attendant seat. The assembly includes a seat pan supported between spaced frame members defining guide tracks including successive pivot positions each corresponding to a different seat pan height. The seat pan is movable between a deployed condition and a stowed condition in which the seat pan stows generally vertically below a backrest to provide a low profile seat in the stowed condition. Features provided on opposing sides of the seat pan interact with the successive pivot positions in the guide tracks, and the seat can be repositioned to a different pivot position to change the seat pan height. Pivoting motion of the seat pan between the stowed and deployed conditions locks or unlocks the seat pan relative to its aligned successive pivot position.Type: GrantFiled: July 13, 2021Date of Patent: January 10, 2023Assignee: B/E Aerospace, Inc.Inventors: Nikhil Anthony Saldanha, Naveen B. Lokanatha

Publication number: 20220380058Abstract: An inflation control system for an inflatable may comprise a compressed fluid source, a valve module, a temperature sensor, and a controller. The valve module is connected to the compressed fluid source and configured to control a flow of gas to the inflatable. The temperature sensor measures an ambient temperature and outputs the ambient temperature measurement. The controller is operably coupled to the valve module and configured to receive the ambient temperature measurement and determine an open-valve time based on the ambient temperature measurement, the open-valve time being a duration of time the valve module is in an open position.Type: ApplicationFiled: February 21, 2022Publication date: December 1, 2022Applicant: GOODRICH CORPORATIONInventors: Poly Puthur John, Nikhil Anthony Saldanha, Bhavik Mugeraya
