  • Patent number: 11352140
    Abstract: The invention mainly relates to a system for the inertial unlocking of a seat back, in particular of an aircraft seat, characterized in that it comprises: a structural element of the seat back, called a connecting rod, a support piece for the fixation to a structural element of said seat, the support piece comprising a flyweight movable in translation between: a locking position in which the flyweight faces a lip of the connecting rod so as to prevent the connecting rod from rotating relative to the support piece about the axis of rotation, and an unlocking position in which the flyweight is released from the lip of the connecting rod so as to allow the connecting rod to rotate relative to the support piece about the axis of rotation, the passage of the flyweight from the locking position to the unlocking position being able to be carried out under the action of a deceleration by the seat.

  • Patent number: 10562634
    Abstract: Described are pivoting and sliding tray tables (10) that move through a substantially constant plane from a stowed position to a deployed position for use with passenger seats. The tray table (10) rides on two elements (14, 18) that themselves ride along guide tracks or guide rails (21, 22, 23) to provide a combination rotating and translating motion during deployment. In the deployed position, the tray table may be displaced linearly but is restricted from rotation. The tray table may be moved to accommodate passengers of differing size or to allow ingress and egress from the passenger seat with a reduced risk of unintentional rotation.

  • Patent number: 10507924
    Abstract: Embodiments of the present invention provide systems and methods for installing seats in a passenger vehicle using seat tracks and seat fittings. The seat track fittings may include a sleeve (22) with a cylindrical threaded opening (24), a double effect post (26) with an external lower thread (28) and an internal threaded portion (36). The external lower thread is configured to cooperate with the cylindrical threaded opening of the sleeve. The seat track fitting also has a track stud (38) with a lower flange (46) that is configured to cooperate with a seat track (10) and an upper external thread (42) configured to cooperate with the internal threaded portion of the double effect post. The double effect post external lower thread and the track stud external thread have inverse hands, such that rotation of the double effect post tightens the post and the track stud simultaneously.
