ABSTRACT:
A passenger seat, an aircraft passenger seat in particular, has seat components such as a seat frame (20), a backrest (12), and a seat cushion carrier (30) with seat cushion (16). The seat depth between backrest (12) and a seat front edge (26) can be varied by an adjustment mechanism (32) with an energy accumulator, such that the seat depth is adjustable and fastenable in desired adjustment positions. The adjustment mechanism has at least one variable-volume energy accumulator. An adjustment position of the seat depth may be associated with each volume level. The seat depth adjustment may be effected essentially free of mechanical components such as sets of levers.
