DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to equipment for air, sea, road and rail public transport vehicles and to transit areas.
All the relative or absolute figures given hereinafter are of an approximate nature and can vary as a function of the enclosed area, hereinafter referred to as the cabin, as well as the degree of luxury. In addition, for reasons of clarity, the seats for sitting have planar faces. The luxury of an individual choice between a sitting position in companionship and a stretched out position in isolation has only been an unprofitable dream.
SUMMARY OF THE INVENTION
The present invention provides the means for ensuring profitability. The choice is based on conventional sitting-type seats, which are located on the ground and in optimum four-person compartments, and extended seats or loungers, which are placed above the sitting seats. The profitability is based on the following gains. (1) Gain of between 13 and 25% or even more in the total number of sitting, plus lounger seats, compared with the conventional ground level filling of the same cabin. (2) Gain of a volume of between 80 and 200% in the individual stowing of baggage, compared with conventional stowing arrangements. (3) Gain in security of baggage, which are in the immediate vicinity of the owner, those on the ground being padlockable (4) Improvement in the efficiency of a better channelled air conditioning air. (5) Better balancing of the traffic flow, persons being attracted to the off-peak services when there is a better choice of positions. The absence of any overcrowding sensation is explained by the fact that the invention recovers 30% of the volume of the cabin which was previously unused, namely at the top under the curved roof area and on the ground below the sitting seats.
The invention is based on the following. As a result of gravity, any person rising from a sitting seat follows a square pattern with his head in a single direction. Thus, before rising, the head and bust must pivot forwards around the hips in order to bring the center of gravity of the body vertical with respect to the feet, so as to then be able to rise vertically by 40 cm, i.e. the length of the femur which passes from the horizontal to the vertical. This takes place in the reverse order for sitting down. Thus, e.g. in the case of a vehicle provided with rows of transverse sitting seats on either side of a longitudinal passageway or corridor, the front face of the space used by the occupants of these sitting seats is not a horizontal plane, but an undulating cylindrical surface with transverse undulations with a vertical amplitude equal to the 40 cm femur, which corresponds to the height difference between a sitting occupant and a standing occupant. This orientation can only be used above the rows of sitting seats having an alternating successive orientation, because it is then continuous and of considerable length in the same way as the profile of a lounger with a central bottom point and with raised ends at the head and feet. Access to the central bottom point takes place by means of steps positioned facing the edge of the passageway between the back to back seat backs.
This supplementary level of loungers eliminates the conventionally used racks for stowing the baggage of the occupants of the sitting seats. However, through the alternately oriented rows, under each pair of back to back sitting seats is formed two individual baggage stowing zones with a much larger volume than that conventionally allocated with sitting seats. This is for two reasons, namely, for equal ease, the spacing of the alternately oriented sitting seats exceeds by 10% the double single spacing of sitting seats in the same direction and each stowing zone is extended beneath the vertical of the seat back, which would be impossible with the seats in the same direction. Access to each stowing zone on the ground is obtained by raising the horizontal part of the seat. However, this prevents the use of a collapsible median tray for the facing seats. This i
