Abstract: The invention relates to a passenger seat for a public transport vehicle, in particular an aircraft, the seat including at least one armrest 1 and at least one individual video display 2 associated with the armrest 1, said seat being characterized in that the video display 2 is retractably mounted via a slot 3 provided in a top wall 4 of the front portion 5 of the armrest 1.

Abstract: A hinge device for seats of public transport vehicles--especially airliners--adapted to allow the seat squab frame (2) to tilt relative to the seat cushion frame (3) about a tilt axis (4). The seat squab frame (2) is generally U-shaped with the web forming the top of the seat squab frame (2) and the sides forming the lateral edges (6) of the seat squab frame (2). The seat cushion frame (3) has a rear part (7) including two rear free ends (8). The tilt axis is horizontal and passes through the rear free ends (8) of the seat cushion frame (3) and the free ends (9) of the lateral edges (6) of the seat squab frame (2).

Abstract: The invention relates to an underframe for a passenger aircraft seat, the underframe including a triangular base defining a front anchor point and a rear anchor point, and a raised intermediate vertex; and a leg associated via its top end with the structure of the seat and via its bottom end with the triangular base. In accordance with the invention, the leg is associated rigidly with the base by rigid association means which, during normal use of the seat, hold the leg positively relative to the base, in particular so as to prevent any forward or backward pivoting of the leg.

Abstract: An underframe for a passenger aircraft seat, the underframe including at least one element forming a front leg and at least one element forming a rear leg, and energy absorption structure that is active when a moving element of the seat moves relative to another element of the seat or of the floor of the aircraft cabin, under the effect of the seat being subjected to deceleration above a predetermined value. The energy absorption structure includes an energy absorption device including a male part that penetrates by force and with plastic deformation into an aperture in a female part. Either the female part or the male part is attached on and directly associated with the moving element, and the other part, i.e. the male part or the female part, is attached on and directly associated with the other element.
