Abstract

A support pallet includes:
a body, lock attachment means each created in a portion of the body, the lock attachment means each making it possible to establish an attachment between the body and a seat rail lock or with an intermediate connecting part, seat unit attachment means each created in a portion of the body, the seat unit attachment means cach making it possible to establish a connection between the body and an element of the seat unit, the portions of the body comprising the lock attachment means and the portions of the body comprising the seat unit attachment means, and the rest of the body forming a single monolithic part.

First claim

The invention claimed is:

1. A support pallet for an airplane seat unit comprising:
a body comprising an upper face and a lower face;
a plurality of lock fixing means, each lock fixing means of the plurality of lock fixing means formed in a corresponding portion of the body, wherein each lock fixing means of the plurality of lock fixing means defines a fixation point such that the plurality of lock fixing means define a plurality of fixation points, wherein each fixation point is configured to engage at least one of a corresponding seat rail lock or a corresponding intermediate connecting piece to the body; and
a plurality of seat unit fixing means, each seat unit fixing means of the plurality of seat unit fixing means provided in a corresponding portion of the body, wherein each seat unit fixing means of the plurality of seat unit fixing means defines a fixation point for attaching the body to an element of the airplane seat unit,
wherein said support pallet further comprises a plurality of stiffening ribs, and wherein:

the plurality of stiffening ribs extend in paths along the body between the plurality of lock fixing means such that, at least between a first lock fixing means and a second lock fixing means of the plurality of lock fixing means, at least two stiffening ribs of the plurality of stiffening ribs extend therebetween,
the stiffening ribs integral with the body are arranged on the lower face of the body of the support pallet, and
the upper face of the body is smooth,
wherein the support pallet constitutes a single piece,
wherein the body of the support pallet includes a main portion and an elongated arm, the elongated arm being defined between a lock fixing means and two seat unit fixing means, the elongated arm having a maximum width inferior to a maximum width of the main portion, and
the elongated arm includes a through recess.

2. The support pallet according to claim 1 , characterized in that the plurality of lock fixing means comprises three lock fixing means.

3. The support pallet according to claim 2 , characterized in that the three lock fixing means comprises a first lock fixing means and a second lock fixing means configured to align with a first seat rail of an aircraft floor and a third lock fixing means configured to align with a second seat rail of the aircraft floor.

4. The support pallet according to claim 3 , characterized in that the third lock fixing means is longitudinally offset with respect to a first straight line perpendicular to a longitudinal direction through the first lock fixing means and with respect to a second straight line perpendicular to a longitudinal direction through the second lock fixing means, so that the third lock fixing means is longitudinally located between the first lock fixing means and the second lock fixing means.

5. The support pallet according to claim 1 , further comprising at least one through recess is defined in the body configured to reduce weight of the support pallet and/or allow passage of electrical wires.

6. The support pallet according to claim 1 , characterized in that the single piece is made of a metallic material.

7. An assembly comprising:
at least one seat unit; and
a support pallet of claim 1 connected to the at least one seat unit.

8. A support pallet for an airplane seat unit comprising:
a body comprising an upper face and a lower face;
a plurality of lock fixing means, each lock fixing means of the plurality of lock fixing means formed in a corresponding portion of the body, wherein each lock fixing means of the plurality of lock fixing means defines a fixation point such that the plurality of lock fixing means define a plurality of fixation points, wherein each fixation point is configured to engage at least one of a corresponding seat rail lock or a corresponding intermediate connecting piece to the body; and
a plurality of seat unit fixing means, each seat unit fixing means of the plurality of seat unit fixing means provided in a corresponding portion of the body, wherein each seat unit fixing means of the plurality of seat unit fixing means defines a fixation point for attaching the body to an element of the airplane seat unit,
wherein said support pallet further comprises a plurality of stiffening ribs, and wherein:

the plurality of stiffening ribs extend in paths along the body between the plurality of lock fixing means such that, at least between a first lock fixing means and a second lock fixing means of the plurality of lock fixing means, at least two stiffening ribs of the plurality of stiffening ribs extend therebetween,
the stiffening ribs integral with the body are arranged on the lower face of the body of the support pallet, and
the upper face of the body is smooth,
wherein the support pallet constitutes a single piece,
wherein the stiffening ribs are defined in a predetermined pattern which is asymmetrical in both a longitudinal and lateral direction of the body.

9. The support pallet according to claim 8 , characterized in that the plurality of lock fixing means comprises three lock fixing means.

10. The support pallet according to claim 9 , characterized in that the three lock fixing means comprises a first lock fixing means and a second lock fixing means configured to align with a first seat rail of an aircraft floor and a third lock fixing means configured to align with a second seat rail of the aircraft floor.

11. The support pallet according to claim 10 , characterized in that the third lock fixing means is longitudinally offset with respect to a first straight line perpendicular to a longitudinal direction through the first lock fixing means and with respect to a second straight line perpendicular to a longitudinal direction through the second lock fixing means, so that the third lock fixing means is longitudinally located between the first lock fixing means and the second lock fixing means.

12. The support pallet according to claim 8 , further comprising at least one through recess is defined in the body configured to reduce weight of the support pallet and/or allow passage of electrical wires.

13. The support pallet according to claim 8 , characterized in that the single piece is made of a metallic material.

14. An assembly comprising:
at least one seat unit; and
a support pallet of claim 8 connected to the at least one seat unit.
