Abstract: A passenger chair or a group of passenger chairs, particularly in an aircraft cabin, is equipped with a convenience device that includes an open storage bail which can hold only flat articles but not waste material, and a waste container for holding waste material but not flat articles. The storage bail and waste container form either a mounting unit or retrofit kit or are separate components. In both instances the mounting unit and the separate components are secured to a back facing area of a chair or group of chairs. The separate components are preferably so constructed that individual retrofit kits are provided.

Abstract: A seating space such as an aircraft passenger cabin has rows of seats along an aisle, identified by a row number and a seat location letter. A seat row indicator is arranged on the side flank of the seat back of each aisle seat, at the corner where the side flank and upper edge of the seat back meet. A seat location indicator is arranged at the middle of the upper edge of the seat back of each seat. The row numbers and seat letters are indicated on or in the indicators by paint, printing, engraving, inserts, illumination or tactile indicia. The indicators are conspicuous and easily visible to a passenger standing or walking in the aisle without bending or leaning over. Boarding of the aircraft is facilitated and expedited. Emergency evacuation is assisted by appropriate illumination of the indicators.

Abstract: An aircraft passenger chair has a support frame, a seat and a backrest. A position adjustment mechanism is coupled between the frame and the backrest by a unidirectional force transmission to permit tilting the backrest clockwise forward into a parking position while simultaneously shifting the seat backward independently of the position adjustment mechanism to increase the space between two rows of seats. Operating the position adjustment mechanism tilts the backrest counterclockwise from an upright position into a rest position and returns the backrest into its upright position. Bringing the backrest into the parking position and shifting the seat simultaneously backward is independent of tilting the backrest into a rest position. Similarly returning the backrest and the seat into the respective normal position is also independent of returning the backrest from the rest position into the normal position.

Abstract: A safety belt system especially for a passenger chair has at least one, preferably two, safety components each of which includes a controlled flexibility. The controlled flexibility is provided by a relatively stiff sheath or whip or belt section. A limp belt member passes through the sheath with the controlled flexibility. In a second embodiment, the controlled rigidity is provided by a flexible belt end section. In both embodiments one end of each safety component is secured to the chair and the other end has a belt lock element for closing the belt system for use. In an open rest position at least one, preferably both, safety components rest against the backrest of the chair. The controlled flexibility provides a spring biasing force that keeps the safety component in the rest position from which the passenger can turn the safety component into a use position and close the system with one hand.
