Passenger seat, an aircraft passenger seat in particular

1. A passenger seat, comprising:

a seat carrier, which is adapted to be mounted on a cabin floor;

a seat component with a seat bottom connected to said seat carrier by a joint assembly such that said seat bottom is pivotable about a first pivot axis relative to said seat carrier for movement between selected positions thereof; and

an occupant fastening mechanism coupled to said seat bottom to lock said seat bottom in the selected positions and to release said seat bottom for movement between the selected positions, said fastening mechanism including at least two hydraulic locking elements wherein

said seat bottom is pivotable about a second pivot axis relative to said seat carrier, and said first axis is perpendicular relative to said second pivot axis;

said first pivot axis extends in a longitudinal direction of the seat; and said second pivot axis extends in a transverse direction of the seat;

said seat carrier comprises a main extension direction that is horizontal and in said transverse direction;

said hydraulic locking elements extend between said seat bottom and said seat carrier, and lengths of said hydraulic locking elements determine tilting of said seat bottom about said second pivot axis and unequal relative lengths of said hydraulic locking elements determine tilting of said seat bottom about said first pivot axis; and

said hydraulic locking elements are mounted on a front end of said seat carrier, extend parallel to said front end, and are inclined with respect to each other.

2. A passenger seat according to claim 1 wherein said seat carrier has a longitudinal axis parallel to said second pivot axis and horizontal relative to said cabin floor.

3. A passenger seat, comprising:

a seat carrier;

a seat component with a seat bottom connected to said seat carrier by a joint assembly such that said seat bottom is pivotable about a first pivot axis relative to said seat carrier for movement between selected positions thereof; and

an occupant fastening mechanism coupled to said seat bottom to lock said seat bottom in the selected positions and to release said seat bottom for movement between the selected positions, said fastening mechanism including at least one hydraulic locking element, wherein

said seat bottom is pivotable about a second pivot axis relative to said seat carrier, said first and second pivot axes forming an angle therebetween

said first axis is perpendicular relative to said second pivot axis

said first pivot axis extends in a longitudinal direction of the seat;

said second pivot axis extends in a transverse direction of the seat

said joint assembly comprises first and second joints between said seat bottom and said seat carrier, wherein the joints are separated from one another along said first pivot axis in a longitudinal direction of the seat,

one said first movable joint including a ball-and-socket joint to form said second pivot axis, and

said second movable joint including a tenon-and-slot joint providing pivoting and horizontal displacement.

4. A passenger seat according to claim 3 wherein

said first movable joint is mounted between rearward areas of said seat carrier and of said seat bottom; and

said second movable joint is mounted on a joint support on said seat bottom located forwardly of said first movable joint.

5. A passenger seat according to claim 4 wherein

said joint support comprises arms extending from both sides of said first pivot axis along said seat bottom; and

said fastening mechanism comprises two hydraulic locking elements between said seat carrier and ends of said arms enabling displacement movement and pivoting movement between the selected positions and locking in the selected positions on the second movable joint.

6. A passenger seat according to claim 1 wherein said joint assembly comprises a universal joint.

7. A passenger seat, comprising:

a seat carrier;

a seat component with a seat bottom connected to said seat carrier by a joint assembly such that said seat bottom is pivotable about a first pivot axis relative to said seat carrier for movement between selected positions thereof; and

an occupant fastening mechanism coupled to said seat bottom to lock said seat bottom in the selected position and to release said seat bottom for movement between the selected positions, said fastening mechanism including at least one hydraulic locking element, wherein

said seat bottom is pivotable about a second pivot axis relative to said seat carrier, said first and second pivot axes forming an angle therebetween

said first axis is perpendicular relative to said second pivot axis

said first pivot axis extends in a longitudinal direction of the seat;

said second pivot axis extends in a transverse direction of the seat

said seat carrier comprises a main extension direction that is horizontal and in said transverse direction;

a displacement guide having a guide slot open on a top thereof is fastened on said seat carrier; and

a guide pin is movably received in said guide slot during pivoting movement of said seat bottom about said second pivot axis.

8. A passenger seat according to claim 7 wherein said guide pin is coupled to a joint support connected on a front area of an underside of said seat bottom.

9. A passenger seat according to claim 8 wherein

said fastening mechanism comprises at least two hydro lock elements; and

said joint support comprises two arms with ends pivotally and respectively connected to each of said hydro lock elements.

10. A passenger seat according to claim 1 wherein the seat is an aircraft passenger seat.

11. A passenger seat according to claim 1 wherein a backrest and an armrest are coupled to said seat component.
