Patent number: 11597520Abstract: A component positioning system and method are configured to facilitate positioning of a component (such as a seat assembly) on a seat track within an internal cabin of a vehicle. The component positioning system and method include a component, and a position indicator coupled to a portion of the component. The position indicator emits a proper position indication when the component is in a proper position in relation to the seat track. The position indicator emits a remedial position indication when the component is not in the proper position with respect to the seat track.Type: GrantFiled: November 1, 2019Date of Patent: March 7, 2023Assignee: THE BOEING COMPANYInventors: James Jason Salmon, Jeffrey Scott Roberts, Patrick William O'Neill

Patent number: 11597521Abstract: A modal restraint system for an occupant of a seat of an aircraft. The modal restraint system includes a strap feeder unit and a strap selectively retractable into and extendable from the strap feeder unit. The strap feeder unit is adapted to switch between a plurality of modes including an unfixed mode and a fixed mode. The strap is extendable from and retractable into the strap feeder unit in the unfixed mode. The strap is substantially unextendable from the strap feeder unit in the fixed mode. The strap feeder unit is in the unfixed mode by default. The strap feeder unit is operable to switch from the unfixed mode to the fixed mode in response to a precautionary event including detection of an operational parameter that is beyond a predetermined threshold, thereby reducing freedom of movement of the occupant relative to the seat.Type: GrantFiled: December 5, 2021Date of Patent: March 7, 2023Assignee: Textron Innovations Inc.Inventors: Eric A. Sinusas, Olivier Andre Boisvert, Guillaume Noiseux-Boucher, Steve Loveland, Sebastien Duval

Patent number: 11597522Abstract: A passenger seat or group of seats includes a tray table set into the armrest on either side of the associated seat, the tray table capable of translating lengthwise along the armrest and pivoting between a stowed configuration and a deployed configuration. In the stowed configuration, the tray table extends vertically above the armrest and may be stowed between (and partially behind) the associated seat and an adjacent seat, serving as a partial barrier between the two seats. In the deployed configuration, the tray table extends horizontally across the associated seat for use by the occupying passenger. The tray table is padded on its underside to provide the passenger with head and shoulder support when in the stowed configuration.Type: GrantFiled: April 19, 2021Date of Patent: March 7, 2023Assignee: B/E Aerospace, Inc.Inventor: Ian L. Frost
