Secure herringbone arrangement for the armrest of a seat, seat and two seat assembly provided with such an arrangement
View Patent ↗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. The present invention also relates to a seat and a seat assembly provided with such an arrangement.
1. An aircraft seating assembly comprising:
a. a seating portion (i) configured when in use to support an aircraft passenger in at least a seated position and (ii) having first and second generally parallel lateral edges;
b. a seat back which, together with the seating portion, defines a longitudinal seat axis;
c. an armrest (i) laterally spaced from the first and second lateral edges of the seating portion, (ii) defining a longitudinal armrest axis that is permanently shifted at a fixed, non-zero angle with respect to the longitudinal seat axis, (iii) having an external wall, (iv) comprising shock-absorbing material, (v) configured when in use to support an arm of an aircraft passenger seated in the seating portion, and (vi) movable vertically between a high position and a low position;
d. means for locking the armrest in the high position;
e. a storage pocket integrated under the lateral space between the armrest and at least the first lateral edge of the seating portion;
f. a shell (i) surrounding the external wall of the armrest and (ii) having a back face; and
g. a video screen integrated in the back face of the shell.
2. An aircraft seating assembly according to claim 1 in which the armrest includes a support and a horizontal plate, with the horizontal plate being wider than the support, so that a part of the horizontal plate protrudes from the support on a side of the support which faces the seating portion.
3. An aircraft seating assembly according to claim 1 in which the shell is made of a thermosetting material.
4. An aircraft seating assembly according to claim 1 in which the seat back has a height and at least a portion of the shell has a height substantially equal to the height of the seat back.
5. An aircraft seating assembly according to claim 1 in which the shell has a reinforcement with a footrest integrated therein.
