  • Patent number: 8690254
    Abstract: In herringbone seats of the prior art, armrests on the closed angle side form an obstacle for the passengers in the seat in case of a shock, since the latter are generally projected along the axis of the vehicle and thus towards the armrest thus creating a high risk of injury for the passenger in case of a shock. The present invention provides a secure herringbone arrangement for the armrest of a seat i.e. making it possible to reduce the risk of injuries caused by the armrest, in case of a shock. Therefore, the present invention provides to leave a space between the seating part structure and the armrest to enable the passenger on the seat to be projected along the axis of the airplane in case of a shock without hitting the armrest. More precisely, the aim of the invention is a herringbone arrangement for the armrest of a seat wherein the armrest is angularly shifted with respect to the seat, so as to form a free space (33) between the seat and the armrest.

  • Publication number: 20120205958
    Abstract: An armrest assembly is provided for adjusting an armrest of a seating unit in three degrees of motion. The armrest assembly includes an angle-adjustment mechanism that allows the armrest to pivot and to translate forward, and a lift mechanism that enables vertical articulation of the armrest. The angle-adjustment assembly includes a pivot bracket with a downwardly disposed pin and a shuttle with an arcuate slot to receive the pin. The arcuate slot includes contoured walls that form detents for restricting movement of the pin, thereby restraining rotation of the shuttle, with respect to the pivot bracket, to predefined angular positions. The lift mechanism includes a rack with ride element(s) extending therefrom and locking teeth, and a control bar with track(s). An upward manual actuation of the control bar causes the track to shift laterally and retract the locking teeth, via interaction between the track(s) and ride element(s), respectively.
