A deployable ottoman extension fills the gap between the ottoman and fully reclined oblique aircraft seat. The deployable ottoman extension can pivot out from the ottoman about a pivot point and/or slide out along a rail. Alternatively, the ottoman extension may be hinged to the ottoman to deploy by flipping down. The deployable ottoman extension may include deployable support features that extend to the aircraft floor when deployed.

An override bypass assembly comprises a cable and a pulley wheel operably connected to the cable. The cable in operation rotates the pulley wheel when tension is applied to the cable. The override bypass assembly also comprises a telescoping cylinder assembly operably connected to the pulley wheel. The pulley wheel in operation moves the telescoping cylinder assembly to an unlocked position. The override bypass assembly further comprises a biasing mechanism operably connected to at least one of the pulley wheel and the telescoping cylinder assembly. The biasing mechanism in operation moves the telescoping cylinder to a locked position when tension applied to the cable is relieved.

A rotational brake assembly comprises: a swivel disc having an outer diameter and a plurality of locking holes proximate the outer diameter; a cam having an angled slot; a lifting pin located within the angled slot of the cam; and a rotational brake pin operably connected to the lifting pin. The cam in operation moves to at least one of a locked position and an unlocked position based on an input. The lifting pin in operation moves along the angled slot when the cam moves. The rotational brake pin in operation moves due to motion of the cam. The rotational brake pin in operation moves from an engaged position with the swivel disc to a disengaged position, when the cam moves from the locked to the unlocked position. The rotational brake pin in operation moves to the engaged position, when the cam moves to the locked position.

A seat locking mechanism comprises: a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and a carriage assembly operably connected to the plurality of positional brake mechanisms. The carriage assembly having a carriage tube and a carriage housing fixedly connected to the carriage tube. The carriage assembly in operation moves each of the plurality of positional brake mechanisms to at least one of a locked position and an unlocked position, when the carriage assembly rotates.

A seat locking mechanism comprises a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and an electric motor assembly operably connected to each of the plurality of positional brake mechanisms. The electric motor assembly comprises: a drive motor; a clutch system located between the drive motor and the plurality of positional brake mechanisms; and a solenoid operably connected to the clutch system. The solenoid in operation engages the clutch system to operably connect the electric motor to the plurality of positional brake mechanisms when the electric motor assembly is activated and disengages the clutch system to operably disconnect the electric motor to the plurality of positional brake mechanisms when the electric motor assembly is deactivated. The electric motor assembly in operation moves the plurality of positional brake mechanisms to at least one of a locked position and unlocked position.

A headrest for a seat having a backrest frame and a base. The headrest includes a displacement member mountable to the backrest frame to position a lower end of the displacement member in front of the backrest frame and above the base. The displacement member is displaceable relative to the backrest frame to adjust a height of the headrest. A tilt member extends between a pivot end pivotably mounted to the displacement member at a joint, and a head support end disposed above the pivot end to support a rear portion of the head. The joint defines a pivot axis and is positioned in front of the backrest frame and above the base. The tilt member is pivotable about the pivot axis to displace the head support end toward and away from the displacement member.

Arrangements for safety and comfort in vehicles.

A contoured stowable seat is provided. The contoured stowable seat may comprise a housing, a seat pan, a contoured backrest, and a deployment lever. The contoured stowable seat may be configured to be in a stowed position and a deployed position. In response to the seat pan being in the deployed position, the deployment lever may contact the contoured backrest, causing the contoured backrest to deploy and form into a contoured shape. The contoured stowable seat may also further comprise a tension cord and a headrest. The contoured backrest may also further comprise a cushion located on the outer surface of the contoured backrest.

A reclinable passenger seat including a base, a seat pan frame having a front end connected to the base via a first fixed pivot, a support arm having one end connected to the base via a second fixed pivot aft of the first fixed pivot, and a backrest frame having an upper backrest member and a lower backrest member. An opposed end of the support arm is pivotally connected to the lower backrest member at a first location spaced from the upper backrest member. A rear end of the seat pan frame is pivotally connected to the lower backrest member at a second location between the first location and the upper backrest member. The backrest frame and seat pan frame are configured to move simultaneously between a sitting configuration and a reclined configuration through pivoting motion about the fixed pivots and about the two locations.

The present invention is a portable, intelligent, ergonomically adjustable body-seat cushion controlled wirelessly via a smartphone or tablet app. Multiple air bladders embedded in the body-seat cushion inflate/deflate at the direction of the app to manipulate the physical position of the user's neck, back, posterior, legs, and feet in order to: (1) alleviate pressure on the back and sit-bones; (2) lengthen the user from a normal sitting position to a lengthened sitting position; and (3) increase blood flow to the user's extremities. Positioning algorithms in the app use the user's anthropometric data (body measurements) and seat measurements (including available space above and in front of the seat) to generate one or more air bladder fill instructions to lengthen the user. The app then wirelessly transmits the positioning instructions as well as optional motion, temperature, and vibration instructions to one or more wireless receivers in the seat cushion.
