Aircraft passenger seat having a movably mounted seat base
The invention relates to an aircraft passenger seat, comprising a frame intended to be fastened to a floor of an aircraft passenger cabin, a seat base movably mounted on the frame, and a movably mounted seat back. The aircraft passenger seat is characterized in that at least one rail is fastened to the frame and in that the seat base is slidably arranged on the rail by means of guide elements.
1. An aircraft passenger seat comprising:
a frame for fastening to a floor of an aircraft passenger cabin;
a seat base mounted movably on the frame;
a backrest, which is movably mounted with the frame and which comprises a backrest enclosure configured as a backrest shell surrounding and enclosing at least an uppermost part of the backrest, so that the backrest is encased within the backrest enclosure in any position of the backrest; and
an adjusting mechanism arranged on the backrest, between the backrest and the backrest enclosure and encased within the backrest enclosure, wherein the adjusting mechanism includes a damping element coupled to the backrest by way a first end in a region of the upper edge of the backrest and coupled to the backrest enclosure by way of a second end in a middle region of the backrest enclosure,
wherein at least one rail is fixed on the frame,
wherein the seat base is arranged on the at least one rail such that the seat base can be displaced via guide mechanisms,
wherein the seat base and the backrest are connected to one another in an articulated manner, whereby the backrest and the seat base coupled to the backrest can be moved together by the adjusting mechanism, and
wherein the backrest is movably and directly connected to the backrest enclosure by at least one articulated lever.
2. The aircraft passenger seat as claimed in claim 1 , wherein two rails are provided.
3. The aircraft passenger seat as claimed in claim 1 , wherein the at least one rail has a guide track for the guide mechanisms.
4. The aircraft passenger seat as claimed in claim 1 , wherein the at least one rail is arranged below the seat base.
5. The aircraft passenger seat as claimed in claim 1 , wherein the guide mechanisms comprise a roller carriage.
6. The aircraft passenger seat as claimed in claim 5 , further comprising a plurality of rollers arranged on the roller carriage.
7. The aircraft passenger seat as claimed in claim 6 , wherein the rollers of the roller carriage, which is arranged displaceably together with the seat base on the at least one rail, are prestressed on the at least one rail.
8. The aircraft passenger seat as claimed in claim 7 , wherein the rollers of the roller carriage, which is arranged displaceably together with the seat base on the at least one rail, are mounted by way of a ball bearing and/or an anti-friction bearing.
9. The aircraft passenger seat as claimed in claim 1 , wherein the at least one rail has guide tracks which lie opposite one another.
10. The aircraft passenger seat as claimed in claim 9 , wherein at least one guide track on the at least one rail is concave.
11. The aircraft passenger seat as claimed in claim 1 , wherein the at least one rail has a guide track which is curved in such a way that the seat base can be moved forward and upward.
12. The aircraft passenger seat as claimed in claim 1 , wherein the at least one rail is mounted on two supporting tubes of the frame which are spaced apart.
13. The aircraft passenger seat as claimed in claim 1 , wherein the backrest is movably and directly connected to the backrest enclosure by a plurality of articulated levers.
