Patent ID: 8075058

Claim:
A passenger seat comprising: a seat base; a backrest; a seat structure for erecting the seat on a floor; and at least one coupling device for coupling a movement of the seat base and a movement of the backrest between an initial position of the seat and at least one comfort position of the seat and vice versa, wherein the backrest moves from the comfort position to the initial position in a travel direction; and the coupling device includes: at least one control member, which can be actuated by movement of the backrest or of the seat base, wherein movement of the backrest moves the seat base and movement of the seat base moves the backrest, between the initial position and the at least one comfort position, the control member includes at least one angle lever, one end of which is rigidly coupled to the backrest, and wherein the angle lever provides a pivot axis about which the seat base is pivotally supported and wherein the pivot axis, at which the seat base is supported by the angle lever, moves downward and in the travel direction when the seat base and the backrest are moved from the initial position to the comfort position; and at least one mechanical drive that includes a plurality of coupling locations for connecting the angle lever to the seat structure, and the angle lever is supported at least two coupling locations of the plurality of coupling locations, and the at least two coupling locations of the plurality of coupling locations are moved relative to the seat structure during a movement of the backrest and the seat base between the initial position and the at least one comfort position of the seat and vice versa, and wherein the at least two coupling locations of the plurality of coupling locations are moved along with the angle lever during the movement of the backrest and the seat base between the initial position and the at least one comfort position of the seat and vice versa, and at every stage of the movement of the seat base and the backrest, one of the plurality of coupling locations is a rearmost coupling location with respect to the travel direction, and the pivot axis, at which the seat base is supported by the angle lever, is located such that, during movement of the seat base and the backrest between the initial position of the seat and the at least one comfort position, the pivot axis lies behind the rearmost coupling location.
