Seat
First Claim
1. 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, whereinthe 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, andat 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, andthe 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.

Abstract
The invention relates to a seat, in particular, a vehicle or aircraft passenger seat with seat components such as a seat base (12), a backrest (14) and a coupling device (16) for coupling the movement of at least one part of the seat components between an exit (I) and at least one comfortable (II) position and vice versa. According to the invention, the coupling device (16) comprises at least one control piece, which may be controlled using the movement of the backrest (14) and/or the seat base (12) and hence by means of at least one further control piece to move the seat base (12) and/or the backrest (14) between said positions (I, II), whereby an adjustment, in particular, tilting movement of the backrest is linked with a simultaneous adjustment movement of the seat base which, preferably in the rearward transition region into the backrest descends by a given amount relative to the front edge of the seat which simultaneously moves forward to increase the seat depth.
