Seat arrangement
First Claim
1. A seat arrangement for an aircraft seat having a seat frame, which is provided for mounting the seat on a cabin floor, and a seat region, comprising:
- a backrest unit with a lumbar region, and the seat region is located below the lumbar region of the backrest unit; and
a kinematic unit including at least first and second kinematic parts, whereinthe backrest unit is coupled to the seat frame by the kinematic unit;
the at least first and second kinematic parts of the kinematic unit are coupled to a first side of the backrest unit and a second side of the backrest unit, respectively,the backrest unit has at least one stiffening member in a the seat region, and the stiffening member transmitting a torsional moment from the first side of the backrest unit to the second side of the backrest unit, andthe at least first and second kinematic parts of the kinematic unit are coupled by the stiffening member.

Abstract
A seat arrangement for an aircraft seat includes a seat frame for mounting the seat on a cabin floor and a seat region. The seat arrangement has a backrest unit and is designed to improve stiffness of the backrest unit against one-sided torsional load. The backrest unit is coupled to the seat frame by a kinematic unit having at least first and second kinematic parts coupled to a first side and a second side of the backrest unit, respectively. A stiffening member is located in the seat region that couples the first and second kinematic parts and is provided for transmitting a torsional moment from the first side of the backrest unit to the second side of the backrest unit.
