BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to a seat and its arrangement according in an aircraft for use by a flight attendant.


DESCRIPTION OF THE PRIOR ART

A known seat of this type forms a unit ready for mounting due to a frame since all essential components of the seat such as the seat proper, the backrest, the headrest, the safety belts, are rigidly mounted to this frame. The installation of such a seat in an aircraft is accomplished by means of screwed connections, whereby securing points on the frame are connected with the floor of the cabin and with an inner cabin wall. In this conventional arrangement the seat loads occurring in the operation of the seat are introduced through the frame into the supporting inner structure of the aircraft such as the floor or the inner wall.
In this connection the following are considered to the disadvantageous, especially due to the frame, namely that the seat requires a substantial space, that it has a relatively high weight, that it provides a low seating comfort, that it is expensive to manufacture, and for example, the installation of the wall in another location causes additional work due to the connections with the floor.
German Patent Publication (DE-AS) No. 1,136,592 discloses a seat for a vehicle, crane, excavator, construction machinery, and the like which has a backrest that is directly secured to a supporting wall
This known seat is tiltably arranged between pipes secured to the wall and to the floor. This type of seat solves the problem of providing for the operator two different seat elevations for a better over view. This type of seat does not provide any teaching for improving a seat for a flight attendant with regard to the space requirement, the weight, the seating comfort, and the production costs.


OBJECT OF THE INVENTION

In view of the above it is the object of the invention to develope a seat of the type mentioned in the preamble in such a way that it has distinct improvements compared to the previous solutions as far as space requirements, weight, seating comfort and production costs are concerned.


SUMMARY OF THE INVENTION

This objective has been achieved in a seat according to the invention forming a seat structure for a flight attendant in an aircraft, by the following features. A first independent completely preassembled seat unit includes a seat section, a mounting, and a support for tiltably securing said seat section in the mounting. A second independent completely preassembled backrest unit includes a backrest cushion and a stiffening. A seat belt system is provided for cooperation with the first and second preassembled units. The mounting of the preassembled seat unit includes readily accessible means for attaching the preassembled seat unit to the cabin wall. The stiffening of the backrest cushion has readily accessible keyhole type openings for attaching the preassembled backrest unit to the cabin wall in such a position relative to the preassembled seat unit that both preassembled units together form a space and weight saving seat.
The main advantage of the seat according to the invention is seen in that the above mentioned frame is avoided which primarily affects the production costs and the weight of the seat.
The present seat may be constructed as a very space saving double arrangement whereby two seats are attached to a wall to face in opposite directions.
The available space in an aircraft is used by the present seat in a space saving manner.
