Abstract

The present invention relates essentially to a double-door module for aircraft seats, characterized in that it comprises:
a first door that is mobile in translation between a stowed position and a deployed position, a second door that is mobile in translation between a stowed position and a deployed position, the first door and the second door overlapping completely when the first door and the second door are simultaneously in the stowed position, and a control system comprising a device for locking and unlocking the first door and/or the second door.

First claim

1 . A double-door module for aircraft seats, characterized in that it comprises:
a first door movable in translation between a stored position and a deployed position, a second door movable in translation between a stored position and a deployed position, the first door and the second door being superposed when the first door and the second door are in the stored position, and a control system comprising a device for locking and unlocking the first door and/or the second door, the locking and unlocking device ( 28 ) comprising, for each door ( 24 . 1 , 24 . 2 ), at least one electromagnetic actuator ( 33 . 1 , 33 . 2 ), which is movable between an inactive position, in which the electromagnetic actuator ( 33 . 1 , 33 . 2 ) is engaged in a locking recess ( 34 . 1 , 34 . 2 ) made in the door ( 24 . 1 , 24 . 2 ), so as to block the translation of said door ( 24 . 1 , 24 . 2 ) into the stored position, and an active position, in which the electromagnetic actuator ( 33 . 1 , 33 . 2 ) is disengaged from the locking recess ( 34 . 1 , 34 . 2 ) so as to enable the door ( 24 . 1 , 24 . 2 ) to move.

2 . The double-door module according to claim 1 , characterized in that it comprises a control device for the displacement of the first door and/or second door from one position to another.

3 . The double-door module according to claim 2 , characterized in that a casing containing the control system is distinct from a housing containing the first door and the second door.

4 . The double-door module according to claim 3 , characterized in that the casing of the control system is arranged in the lower part of the double-door module.

5 . The double-door module according to claim 3 , characterized in that the housing containing the first door and the second door has a thickness (E) between 5 and 10 cm and of approximately 7.5 cm.

6 . (canceled)

7 . The double-door module according to claim 1 , characterized in that the electromagnetic actuator is of the type normally in the inactive position to enable to lock the door in the stored position when the electromagnetic actuator is not powered.

8 . The double-door module according to claim 7 , characterized in that it comprises an elastic return member for the electromagnetic actuator in the inactive position.

9 . The double-door module according to claim 8 , characterized in that the locking and unlocking device comprises, for each door, a first electromagnetic actuator intended to be controlled by a passenger and a second electromagnetic actuator intended to be controlled by a member of the staff.

10 . The double-door module according to claim 9 , characterized in that a first locking recess and a second locking recess, respectively associated with the first electromagnetic actuator and the second electromagnetic actuator, have different geometries.

11 . The double-door module according to claim 2 , characterized in that it comprises an actuating button for a displacement of a corresponding door.

12 . The double-door module according to claim 2 , characterized in that the displacement control device includes at least one deployment actuator and one movement transmission device for moving the deployment actuator towards a corresponding door.

13 . The double-door module according to claim 12 , characterized in that the deployment actuator is a gas cylinder.

14 . The double-door module according to claim 12 , characterized in that the movement transmission device is a belt and pulley device.

15 . The double-door module according to claim 1 , characterized in that the control system includes visual status indicators for the system.

16 . The double-door module according to claim 1 , characterized in that a casing of the control system is incorporated into a step.

17 . A seat unit, characterized in that it comprises a double-door module as defined in claim.

18 . The seat unit according to claim 17 , characterized in that it comprises two seats facing one another, each seat being arranged such that it is substantially laterally aligned with the other seat, and a center console is positioned between the seats, said double-door module being disposed along one side of the central console.
