So as to alleviate the waiting time the passengers usually have to
bear at airports, places dedicated to the effect are conditioned in the corresponding
places, where it is essential to install seat in which the conditions of simplicity,
capacity and comfort are appropriately conjugated, within the practical utility
concept of their application.
In this sense, according to the present invention, a block of seats
is proposed, which are particularly dedicated to that function at the airports,
although obviously their application is extensive to any place where they have
practical use, being developed the mentioned block of seats according to some features
both in their construction and assembly and in their ergonomics in their later
use, which makes them particularly advantageous.
This block of seats object of the invention is made up of a bearing
structure including some supports used as legs, on which two longitudinal beams
are fixedly incorporated, regarding which an angular cover made up of sections
which determine consecutive seating surfaces in connection with their respective
back surfaces are fixed by means of some complementary fixing fittings.
The cover sections can be made up of plates of wood or plate, etc...
but a realization is particularly foreseen, according to which each section is
made up of some extruded aluminium side profiles in which some laminar structures
are held made up by a braided core covered with synthetic material, with a layer
of fluffy material superimposed at the front part and a aesthetic lining covering
the whole set at the front and at the back, having the associated core at its side
edges some PVC ribs, by means of which the connection is established with respect
to the side profiles by means of sliding fitting in the corresponding grooved recesses
The fastening devices on the bearing structure are made up of both
adaptable parts by means of side fitting, one of which is established fixedly together
with the corresponding longitudinal beam of the bearing structure and the other
fastened on the respective profile of the cover, determining this piece reciprocal
connection forms, between which a guiding is established, which eases up the connection,
including a tensile screw assembly, thanks to which an appropriate stretching
of the laminate structure of the cover sections is possible, by traction of the
side edges of the core of the mentioned laminar structures between the corresponding
This way a block of seats is obtained whose structure is very easy
to assemble and in which the resistance, functionality and design are conjugated
in an appropriate way, giving it own life and preferable character for the application
to which it is destined.

The object of the invention refers to a block of seats, to be used
in airports and similar places, to ease up the resting of the people during the
waiting time they usually have to undergo.
This block of seats is made up of a bearing structure (1), on which
an angular cover (2) is situated which determines a series of consecutive seating
surfaces in correlation to the respective back surfaces.
The bearing structure (1) includes some supports (3) as legs on which
two horizontal longitudinal beams (4) are fixedly incorporated, making up among
all of them a rigid and stable structural set.
The cover (2) itself is made up by means of a series of consecutive
sections, determining an angular set which is fixedly connected respect to the
longitudinal beams (4) of the bearing structure (1), establishing the mentioned
fastening by means of some fittings (5) made up of complementary parts fixed at
one and the other side. Each section of the cover (2) is made up of a seat module,
which in correlation made up the block of seats.
In a general concept, the section components of the cover (2) can
be made up by plates, wood or any other adequate material, but in a particular
and preferable realization the mentioned sections are foreseen made up by some
extruded aluminium side profiles (6), between which some laminar structures (7)
are included, which determine the surface closure between the mentioned profiles
(6) in the seat area and in the back rest area of each of the sections.
The mentioned laminar structures (7) for the surface closure are
made up, in the way represented on figure 9, by a braided core (8) covered with
synthetical material on which at the front a fluffy layer (9) is superposed, covering
the whole at the front and at the back with a covering (10) which packs it and
gives the set the wanted external aspect.
The core (8) of the mentioned laminar structures (7), includes in
a solidary way some PVC ribs (11) or another synthetical material; so that by means
of the mentioned ribs (11) the fastening with respect to the corresponding profiles
(6) is established, by means of a sliding connection of the mentioned ribs (11)
in the corresponding grooved recesses (6.1) of the mentioned profiles (6), according
to an assembly as the one represented on figure 12. Therefore, the ribs (11) will
present preferably a circular transverse section in correspondence with the shape
of the profile housings (6).
On the other hand, the fastening fittings (5) are made up according
to figures 6, 7 and 8, by complementary parts (12 and 13) one of which (12) is
established fixedly joined to the longitudinal beam (4) which corresponds to the
bearing structure (1), while the other part (13) is fixed on the respective profile
(6) of the cover (2).
According to a concrete realization, the part (12) that is situated
joined to the longitudinal beam (4) of the bearing structure (1), is foreseen having
a U-shape with the respective by-pass holes (14) and (15) at its sides, while
for part (13) which is fixed on the corresponding profile (6) of the cover (2),
an L-shape is foreseen, establishing the fastening at one of its branches, while
from the other branch at its inner part perpendicularly a hollow cylinder (16)
with threaded inside comes out, and which can pass axially through one of the
side holes (14) of the part (12) having a U-shape.
By means of these fittings (5) the fastening connection at each point
is established by the insertion of the cylinder (16) of the corresponding piece
(13) through the side hole (14) of the respective part (12), including through
the hole (15) of the other part of the mentioned part (12) a screw (17), which
is inserted in threaded union respect to the cylinder (16) of the part (13).
With all this, in the way it can be seen on figures 7 and 8, by means
of the screw (17) threading a progressive approach takes place between the parts
(12) and (13) till the desired fastening torque is reached. The mentioned approach
of the parts (12) and (13) is guided by the sliding of the cylinder (16) through
the hole (14), which eases up the assembly, as once the cylinder (16) of each
fitting (5) is headed in the corresponding hole (14), the set is maintained by
itself in the correlative assembly position, being it only necessary to tighten
the screws (17) for the fastening, so that to carry out the tightening, the whole
set adopts the appropriate position by itself.
A possible assembly is started already incorporating in a fixed way
the profile (6) of one end and inserting in it and in its correlative profile (6)
the corresponding seat and backrest sections of the cover (2), so as to situate
afterwards this second profile (6) in assembly disposition, being guided by the
cylinder passage (16) of the parts (13) through the holes (14) of the piece (12).
In this disposition, the screw threading (17) begins till the correct torque degree
of the sections (2) is reached. This degree of tightening is defined by the reciprocal
stop between the parts (12) and (13).
When this way a seat module has been installed, in the same way is
worked for the following one, making use of the corresponding free side of the
profile (6) of the previous one.
It is clear that the fastening means made up by the parts (12) and
(13) can vary without altering in anything the essence of the invention, since
any fastening solution which allows a progressive approach and the following tightening
will be enough. Also, the section of the profiles (16) can adopt different forms,
whenever the two housings (6.1) are made up by way of rails at its sides, for
the insertion of the ribs (11) of each laminar structure (7).
In figures (14) and (15) two possible examples are shown of the shape
of the mentioned profiles (6), without being these limitative examples.
It has to be pointed out that during the assembly, the progressive
approach that consequently takes place of the parts (13) regarding the corresponding
pieces (12), gives rise to a controlled stretching of the laminar structure (7)
of the surface closure, as the mentioned parts (13) haul the corresponding profiles
(6) and these pull the sides of the mentioned laminar structures (7), establishing
their tightening until the parts (12) and (13) are in touch to one another.
Nevertheless, the stretching that the profiles (6) exercise on the
mentioned laminar structures (7) is only determined exercising the tension effort
respect to the core (8), as the side ribs (11), by means of which the pulling
is produced, are only joined by the core (B), which is thus the one which supports
the effort, without being affected either the fluffy layer (9) or the external
cover (10) by the effort, which could deteriorate them. It is this way that between
the fluffy (9) layer and the front external cover (10) the seams are carried out
by welding at high frequency without these unions being affected by the tightening
of the laminar structures (7). What is more, these seams can be in any direction,
horizontally, in the sense of the tension, vertically or in bias or any combination
of these, as it can be seen on the joined figures, giving rise to multilineal
In any case, so as to avoid that the upper and lower edges of the
mentioned laminar structures (7) get deformed by the tightening tension, some reinforcements
(18) are incorporated on the mentioned edges, which avoid the distortion.
Under the same structural and assembly concept, the laminar structures
(7) which determine the seat and back-rest surfaces can adopt any external appearance,
for instance according to the realizations shown in figures 3, 14, 15, 16, 17
and 18, which are not limitative. It has even been foreseen that the seat and
the back-rest of each module are a unique laminated part (7).
In the same way, the seat block can include a relief (19) in the
back-rests, having the function of head-support, as well as elements (20) between
the seat and the back-rest areas, having an arm-rest function, as it is represented
on figure 19, without modifying the structural concept. These arm-rests (20) will
be fixed to the profiles (6) themselves.
In the way it has been pointed out previously, the profiles (6) can
adopt different traverse sections whenever they make up in their sides the rails
(6.1) for the assembly of the ribs (11). In this sense and according to the realization
represented on figure 15, the profiles (6) allow the sliding assembly and guiding
at their inside by some nuts for the fastening between the profiles (6) and their
parts (13) of the fittings (5); these nuts can also be directly solidarized to
the profiles (6) at the points where they are needed.
The head-rests (19) would be mounted with the same concept of the
seat and backrest.
In figure 22 a version is appreciated in which the block of seats
is supplemented with an upper structure (21) to hold suitcases, the mentioned structure
is foreseen incorporated with lights for the seat user and with later locking
means so as to avoid that the suitcases can be moved away inadvertedly through
the rear. Some foot-supports (22) are also foreseen, mounted with the possibility
of horizontal movement through some sliding guides joined to the seat front and
some supporting wheels of the foot-supports (22) themselves.
Anyway, the general configuration and performance of the block of
seats can vary without modifying the essential facts of the invention, whenever
the laminar structures (7) which make up the seat and the back-rest of each section
of the block, are mounted between a pair of profiles (6) which are separated progressively
during the assembly of the block in a controlled and guided movement which gives
rise to a previous tensioning of the mentioned laminar structures (7) and more
concretely of a resistant core (8) which remains connected to the profiles (6)
through some side ribs (11) since this is really the essence of the present invention.
