Air passenger seat having a frame
Proposed is an air passenger seat having a frame which is provided for attaching to a floor of an aircraft cabin and a backrest which is pivotably or securely mounted on the frame by means of a rotation spindle, wherein the seat has a seat reference point (SRP) which is defined according to the SAE International Aerospace Standard AS8049. According to the invention, the rotation spindle of the backrest has, in a line parallel to the cabin floor and as seen parallel to the direction of flight, a separation n of less than 40 mm from the seat reference point.
1. An air passenger seat having a frame which is provided for attaching to a floor of an aircraft cabin and a backrest which is pivotably mounted on the frame by means of a rotation spindle, wherein the seat has a seat reference point which is defined according to the SAE International Aerospace Standard AS8049, wherein the rotation spindle of the backrest has, in a line parallel to the cabin floor and parallel to the direction of flight, a separation of less than 40 mm from the seat reference point.
2. The air passenger seat according to claim 1 , wherein, as seen in the direction of flight, the rotation spindle is in front of the seat reference point.
3. The air passenger seat according to claim 1 , wherein, as seen in the direction of flight, the rotation spindle is behind the seat reference point.
4. The air passenger seat according to claim 1 , wherein the rotation spindle passes through the seat reference point.
5. The air passenger seat according to claim 1 , wherein the rotation spindle is at the same height as the seat reference point.
