Patent number: 10710725Abstract: A modal restraint system for an occupant of a seat of an aircraft includes a strap feeder unit and a strap selectively retractable into and extendable from the strap feeder unit. The strap is positionable adjacent to the occupant so as to dispose the occupant between the strap and the seat. 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 to the fixed mode in response to a precautionary event, thereby reducing freedom of movement of the occupant relative to the seat of the aircraft.Type: GrantFiled: December 5, 2017Date of Patent: July 14, 2020Assignee: Textron Innovations Inc.Inventors: Eric A. Sinusas, Olivier Andre Boisvert, Guillaume Noiseux-Boucher, Steve Loveland, Sebastien Duval
