A seat or chair especially for a flight attendant in an aircraft has a backrest section and a seat section hinged to each other and to a frame in such a way that the backrest section and the seat section can take up different angular positions relative to each other and relative to a vertical frame or to the horizontal. Thus, the chair can be folded to take up several positions including positions in which the seat section takes up lower or higher elevations above the floor. For this purpose the upper end of the back rest section is pivotally guided in a guide mechanism while the lower end of the backrest section is journalled to the rear portion of the seat section at a journal axis which simultaneously forms the journal axis of a support and guide member also hinged to the seat section. The support and guide member is hinged intermediate its ends to the frame through a fixed journal so that the rear edge of the support and guide member can engage a stop in the frame. The guide mechanism at the upper end of the frame permits a tilting motion and a linear sliding motion of the upper end of the backrest section. Thus, the seat section, the backrest section, and the support and guide member together form a type of crank drive. Several positions of the chair may be adjusted, including a lower seat position in which the seat section is slanted relative to the horizontal for an increased comfort.
A seat, especially for a flight attendant, comprising a frame, a seat section and a backrest section, pivoting guide means for securing an upper end of said backrest section to said frame for permitting a tilting motion and a linear motion of an upper end portion of said backrest section relative to said frame, first journal means for journalling a lower end portion of said backrest section to a rear portion of said seat section at a common journal axis, support and guide means for operatively securing said seat section and said backrest section to said frame, said support and guide means having a free end journalled to said common journal axis, and second journal means journalling said support and guide means intermediate its ends to said frame at a fixed journal axis in said frame, said support and guide means cooperating with said backrest section in the manner of a crank drive.
