Abstract

A passenger seat arrangement for installation in an aircraft comprises a seat unit with a backrest element and a seat element. The seat arrangement also comprises a supporting frame carrying the seat unit and comprising at least one seat mounting, which has a first backrest holder, to which the backrest element can be releasably fixed in a load-transferring manner in a first position on the seat mounting, and a second backrest holder, to which the backrest element can be releasably fixed in a load-transferring manner in a second position on the seat mounting. When the passenger seat arrangement is installed in the aircraft, the backrest element is pivoted in relation to a longitudinal axis of the aircraft in a state in which it is fixed to the first backrest holder relative to a state in which it is fixed to the second backrest holder.

First claim

The invention claimed is:

1. A passenger seat arrangement for installation in an aircraft, comprising:
at least one seat unit with a backrest element and a seat element;
a supporting frame, which carries the at least one seat unit and comprises at least one seat mounting, which has a first backrest holder, to which the backrest element can be fixed in a releasable and load-transferring manner in a first position on the seat mounting, and a second backrest holder, to which the backrest element can be fixed in a releasable and load-transferring manner in a second position on the seat mounting, wherein the backrest element comprises at least one first engaging element, which is configured to engage releasably with at least one complementary second engaging element formed in the first and the second backrest holder, in order to fix the backrest element in a load transferring manner in the first or second position on the seat mounting, wherein the at least one first engaging element is formed on at least one connecting strut of the backrest element and the first and the second backrest holder are respectively provided with at least one receiving opening having the second engaging element, into which the connecting strut formed with the first engaging element can be pushed, in order to engage the first engaging element with one of the second engaging elements; and
a locking mechanism, which locks the backrest element to at least one of the first or the second backrest holder and is configured to move at least one of the first engaging element or the second engaging element of at least one of the first or the second backrest holder between a locking position, in which the first engaging element is engaged with the second engaging element of the first or the second backrest holder, and a release position, in which a movement of the first engaging element in relation to the second engaging element of at least one of the first or the second backrest holder is released,
wherein, in a state of the passenger seat arrangement in which it is installed in the aircraft, the backrest element is pivoted in relation to a longitudinal axis of the aircraft in a state in which it is fixed to the first backrest holder relative to a state in which it is fixed to the second backrest holder, and
wherein the first backrest holder comprises at least one of a first locking bolt or the second backrest holder comprises a second locking bolt, which forms the locking mechanism, wherein the at least one second engaging element is arranged on a circumference of at least one of the first or the second locking bolt, and wherein at least one of the first or the second locking bolt is movable in a direction along a longitudinal direction of the first or the second locking bolt, in order to move the second engaging element of at least one of the first or the second backrest holder between the locking position and release position of the first or the second backrest holder.

2. The passenger seat arrangement according to claim 1 , in which, in the state of the passenger seat arrangement in which the passenger seat arrangement is installed in the aircraft, the backrest element is pivoted by substantially 90° or 180° in relation to the longitudinal axis of the aircraft in the state in which the backrest element is fixed to the first backrest holder relative to the state in which the backrest element is fixed to the second backrest holder.

3. The passenger seat arrangement according to claim 1 , in which the locking mechanism comprises:
at least one spring unit, which loads at least one of the first engaging element or the second engaging element of at least one of the first or the second backrest holder in a direction of the locking position or release position of the second backrest holder.

4. The passenger seat arrangement according to claim 1 , in which the locking mechanism comprises:
a blocking mechanism, which blocks at least one of the first engaging element or the second engaging element of at least one of the first or the second backrest holder in at least one of the locking position or a blocking position of the first or second backrest holder and is movable between the blocking position, in which a movement of at least one of the first engaging element or the second engaging element of at least one of the first or the second backrest holder between the locking position and a release position of the first or the second backrest holder is blocked, and the release position, in which a movement of at least one of the first engaging element or the second engaging element of at least one of the first or the second backrest holder between the locking position and release position of the first or the second backrest holder is released.

5. The passenger seat arrangement according to claim 1 , in which the seat element is fixed to the seat mounting and is provided in a region of the first backrest holder with at least one first clearance, in which, in an installed state of the backrest element on the first backrest holder, at least one of the first backrest holder or the backrest element, is partly accommodated, and is provided in the region of the second backrest holder with at least one second clearance, in which, in an installed state of the backrest element on the second backrest holder, at least one of the second backrest holder or the backrest element, is partly accommodated.

6. The passenger seat arrangement according to claim 1 , further comprising at least one armrest element, configured to be fixed in a releasable and load transferring manner to the backrest element and the seat mounting.

7. The passenger seat arrangement according to claim 6 , in which the armrest element comprises:
a first connecting element, which is configured to engage releasably with a complementary second connecting element attached to the backrest element, in order to fix the armrest element to the backrest element in a load-transferring manner, wherein, the first connecting element and the second connecting element interact in a state in which they are engaged on one another in such a way that a rotational movement of the armrest element in relation to the backrest element is blocked and a translational movement of the armrest element in relation to the backrest element in the direction of a release position of the armrest element is released, in order to release the first connecting element from the second connecting element.

8. The passenger seat arrangement according to claim 6 , in which the armrest element comprises at least one of:
a third connecting element, which is configured to engage releasably with a fourth connecting element attached to the seat mounting, in order to fix the armrest element on the seat mounting in a load-transferring manner, wherein, the third connecting element and the fourth connecting element interact in a state in which they are engaged on one another in such a way that a rotational movement of the armrest element in relation to the seat mounting is blocked and a translational movement of the armrest element in relation to the seat mounting in the direction of the release position of the armrest element is released, in order to release the third connecting element from the fourth connecting element; or
a further blocking mechanism, which is configured to block a movement of the armrest element in a direction of a release position in a state of the armrest element in which it is fixed to the backrest element and the seat mounting.

9. A passenger seat arrangement for installation in an aircraft, comprising:
at least one seat unit with a backrest element and a seat element; and
a supporting frame, which carries the at least one seat unit and comprises at least one seat m
