Aircraft passenger seat
Aircraft passenger seat, wherein the aircraft passenger seat has a frame, a seating area element and a backrest element. The aircraft passenger seat is distinguished in that the backrest element has a first beam and a second beam, wherein the backrest element has an elastic element, wherein the elastic element extends from the first to the second beam, so that the elastic element forms a support area for a back of a user of the aircraft passenger seat, wherein the elasticity of the elastic element is adjustable.
1 . An aircraft passenger seat comprising a base, a seating surface element and a backrest element, wherein the backrest element has a first beam and a second beam, wherein the backrest element has an elastic element, wherein the elastic element extends from the first to the second beam, such that the elastic element forms a support surface for a back of a user of the aircraft passenger seat, wherein the elasticity of the elastic element is adjustable, wherein the elastic element is designed as a stretchable strap or a stretchable band, wherein the elastic element is arranged on the backrest element so as to run around the first and the second beam, wherein a first and a second end of the elastic element are movable toward one another and away from one another, wherein there is a tension device, wherein the first and the second end of the elastic element are connected to a tension element of the tension device, wherein an adjusting element of the tension device engages on the tension element, wherein the tension element can be moved in a direction along a longitudinal axis of the first or the second beam by the adjusting element, such that adjustment of the elasticity of the elastic element takes place during a movement of the tension element, and wherein the elasticity of a first of the plurality of elastic elements is adjustable, wherein the elasticity of a second of the plurality of elastic elements is invariable.
2 . The aircraft passenger seat as claimed in claim 1 , wherein the backrest element has a plurality of elastic elements.
3 . The aircraft passenger seat as claimed in claim 1 , wherein the first and the second beam are connected to one another by a first and a second cross brace, such that the beams and the cross braces form a frame.
4 . The aircraft passenger seat as claimed in claim 1 , wherein the position of the backrest element relative to the base is invariable.
5 . The aircraft passenger seat as claimed in claim 1 , wherein the tension element is designed as a ring, as an eye or as a rod.
6 . The aircraft passenger seat as claimed in claim 1 , wherein the adjusting element is designed as a cable or as a wire.
7 . The aircraft passenger seat as claimed in claim 1 , wherein the aircraft passenger seat has a shaft, wherein the adjusting element is connected to the shaft, wherein, during a rotary motion of the shaft, the adjusting element is wound onto or off the shaft, wherein a position of the tension element is changed by the winding process of the adjusting element.
8 . A seat row comprising an aircraft passenger seat as claimed in claim 1 .
9 . An aircraft having a seat row as claimed in claim 8 .
10 . An aircraft having an aircraft passenger seat as claimed in claim 1 .
