DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows an aircraft 10 which comprises a fuselage 12, at the front of which there is disposed a cockpit 14 in which at least one pilot sits.

In the following description, and by convention, X denotes the horizontal longitudinal direction of the aircraft oriented positively in the direction of advance of the aircraft, that is to say towards the front of the aircraft, Y denotes the transverse direction of the aircraft which is horizontal when the aircraft is on the ground, and Z denotes the vertical direction or vertical height when the aircraft is on the ground, these three directions X, Y and Z being mutually orthogonal.

FIG. 2 shows an assembly 250 which is disposed in the cockpit 14 and in front of a seat 203 for a pilot which comprises a user's space of the aircraft.

The assembly 250 comprises a frame which is fixed to a structure of the aircraft 10 and an instrument panel 204 which is fixed to the frame and which faces the user's space. The instrument panel 204 bears, as is known, various indicators and controls of the aircraft 10 and is positioned in front of the seat 203.

The assembly 250 also comprises a support system 202 which comprises an arm 206 fixed by a first end to the frame and a tray 208 mounted at a second end of the arm 206.

With respect to the general direction of the aircraft 10, the arm 206 is arranged to displace the tray 208 alternately from a retracted position in which the tray 208 is inside the instrument panel 204 to an extended position in which the tray 208 is behind the instrument panel 204 and in front of the pilot and the seat 203, that is to say, more specifically, towards the user's space between the instrument panel 204 and the seat 203. The extended position corresponds to a position of use of the tray 208.

The arm 206 can alternately take two positions, namely, a retracted position which corresponds to the retracted position of the tray 208 and in which the arm 206 is shortened and inside the instrument panel 204, and a lying-flat position which corresponds to the extended position of the tray 208 and in which the arm 206 is recumbent and partly extended from the instrument panel 204.

To facilitate the manipulation of the arm 206, the latter has a handle which allows the arm 206 to be grasped by the pilot. To keep the arm 206 in the lying-flat position, the arm 206 is equipped with locking means which lock it in the lying-flat position when no deliberate action on the part of the pilot is exerted to switch it to the retracted position. These locking means or lock can be any means known to the person skilled in the art, such as, for example, sprung balls. Here, the arm 206 is telescopic.

For the tray 208 to be able to assume an ergonomic position with respect to the pilot, the tray 208 is mounted articulated on the arm 206.

The cockpit 14 also comprises a parcel tray 230 which is disposed alongside the seat 203 and which is within reach of the pilot.

The tray 208 comprises a first attachment means 210 which will be described more specifically hereinbelow.

The assembly 250 also comprises a support 302 which is represented in FIG. 3.

The support 302 comprises a second attachment means 310 which cooperates with the first attachment means 210 to removably fix the support 302 onto the tray 208.

The support 302 also comprises a fixing system 312 which ensures the removable fixing of a touch tablet 50 onto the support 302.

The removability of the fixings ensures that the separation of the elements is performed without impairment and simply and without tools.

Thus, the placement and the removal of the touch tablet 50 are performed simply and it is always positioned and held ergonomically in front of the pilot. When the touch tablet 50 is not in use, it can be stowed away in the parcel tray 230 while remaining mounted on the support 302.

In the embodiment presented in FIG. 2, the instrument panel 204 comprises a window 212 and, as described above, the arm 206 is mounted to slide on the frame and through the window 212 in a direction of translation to be retracted with the tray 208 into the instrument panel 204 when the pilot does not need the tray 208. The direction of translation is overall at right angles to the plane of the window 212 and, here, globally parallel to the longitudinal direction.

In the extended/lying-flat position, the arm 206 and therefore the tray 208 are projected behind the instrument panel 204 with respect to the orientation of the longitudinal direction of the aircraft 10 and therefore towards the seat 203. In the retracted position, the arm 206 and the tray 208 are retracted into the instrument panel 204 by entering through the window 212.

The support 302 comprises a first part 314a and a second part 314b. Each part 314a-b comprises a jaw 316a-b which faces the jaw 316b-a of the other part 314b-a and the touch tablet 50 is positioned between the jaws 316a-b.

The two parts 314a-b are translationally movable with respect to one another between a tightened position in which the two jaws 316a-b are brought closer together and a separated position in which the two jaws 316a-b are moved away from one another. The support 302 further comprises a return means which constrains the two parts 314a-b into the tightened position.

In the embodiment of the invention presented in FIG. 3, the translation of the two parts 314a-b is performed here by two guides 318 which are fixed to one of the parts 314a-b and in which the other part 314b-a slides along the two guides 318.

The return means is, here, a spring 320 fixed between the two parts 314a-b which are narrow and thick to facilitate the handling thereof by the hands of the pilot.

FIG. 4 shows the support system 202 in a particular position, and in which the tray 208 is composed of two sub-trays 208a-b which are mounted articulated with respect to one another about a hinge link that is horizontal and transverse with respect to the direction of translation of the arm 206.

The tray 208 thus comprises a lower sub-tray 208a and an upper sub-tray 208b. The lower sub-tray 208a is fixed to the arm 206 and the upper sub-tray 208b is therefore mounted articulated on the lower sub-tray 208a and it is rotationally movable between a folded position and an unfolded position. The hinge link is produced at the rear edges of the two sub-trays 208a-b when the upper sub-tray 208b is in the folded position.

The first attachment means 210 is disposed on a top surface of the upper sub-tray 208b.

In the folded position, the upper sub-tray 208b is pressed against the lower sub-tray 208a and has the first attachment means 210 oriented upwards to be accessible and visible by the pilot. The bottom face of the upper sub-tray 208b is thus against the top face of the lower sub-tray 208a. In this position, the support 302 and the touch tablet 50 can be fixed to the upper sub-tray 208b.

In the unfolded position, the upper sub-tray 208b is aligned with the lower sub-tray 208a to constitute a larger surface and allow the pilot to place, for example, a meal tray. In this position, the first attachment means 210 oriented downwards is not accessible by the pilot. The top face of the lower sub-tray 208a is then aligned with a bottom face of the upper sub-tray 208b, here the surface not bearing the first attachment means 210.

In the embodiment of the invention presented in FIGS. 3 and 4, the link between the first attachment means 210 and the second attachment means 310 takes the form of a fixing of bayonet type. The second attachment means 310 is fixed here onto the first part 314a, but it can be fixed onto the second part 314b. Although the link between the attachment means 210 and 310 is shown in the case of a tray 208 with two articulated sub-trays 208a-b, it can be implemented also in the case of a simple tray 208.

The second attachment means 310 takes the form of a male cylinder provided with two radially protruding lugs 322 and the first attachment means 210 takes the form of a female cylinder which is contained here within the thickness of the upper sub-tray 208b. The male cylinder and the female cylinder are coaxial with respect to the same cylinder axis.

The female cylinder comprises, for each lug 322, a radial groove 222 which extends parallel to the cylinder axis.

At the bottom of each groove 222, a recess 224 is provided which extends over the periphery of the female cylinder and which is configured to receive a lug 322 for the locking of the second attachment means 310.

Mounting the second attachment means 310 comprises introducing the male cylinder into the female cylinder, and each lug 322 into a groove 222, and, when each lug 322 has reached the bottom of its groove 222, the second attachment means 310, and therefore the support 302, are pivoted about the cylinder axis to introduce each lug 322 into the corresponding recess 224.

In order to allow the tablet 50 to be positioned in landscape or portrait position, each recess 224 extends on either side of the groove 222, thus allowing a rotation of the second attachment means 310 in two opposite directions.

In the embodiment of the invention presented in FIG. 2, the two grooves 222 are aligned with one another and offset by 45° with respect to the longitudinal direction X, and each recess 224 extends to 45° on either side of the groove 222.

The parcel tray 230 can be equipped with a connector which interconnects with a connector of the touch tablet 50 when the latter is in the parcel tray 230 to ensure the electrical recharge of the battery of the touch tablet 50. According to a particular embodiment, the connector of the parcel tray 230 is at the bottom of the parcel tray 230 to allow an easy interconnection of the two connectors simply by lowering of the touch tablet 50.
