Description
The present invention relates to an armrest unit which has two
separate adjustable armrest sections and is especially designed and
adapted to be used between adjacent seats in a multiple seating
unit arrangement.
More particularly, the invention is directed to an adjustable
armrest construction where a movable pivotally connected, or
hinged, armrest section for each side of an armrest unit will have
transverse arcuate movement to, in turn, provide individual
selective positioning to thus accommodate each person that is
seated each side of the armrest means.
In vehicle seating it is generally customary to have a single
armrest member between adjacent seats in a row of seats, and this
single armrest arrangement permits only one of any two adjacent
seat occupants to make use of the intermediate armrest such that
there well may be discomfort for the other seat occupant. Of
course, in a low percentage of instances and where space permitted,
there have been row type seating arrangements where each seat is
provided with its own pair of armrests; however, such armrests have
typically been of the fixed, non-adjustable type.
In order to provide more comfort and a better accommodation for
varying sized persons to be seated in a vehicle, or even to be
seated in theatre seating, it is the intent of the present
invention to provide for a certain amount of transverse
adjustability to the armrest means for each seat occupant in a
multiple seat arrangement. For example, in airplane "first class"
seating it has been customary to provide wider seats and wider
armrests between adjacent seating units so as to provide less
cramped seating for the larger and/or heavier passengers,
particularly in comparison with the seating sizes and arrangements
being used in "coach" seating areas. However, extra wide seats may
actually be somewhat unsuitable for the thin or petite individual
to the extent that the armrests may be too far apart and will cause
some discomfort for the seat occupant to use them.
As heretofore noted, it is thus an object of the present invention
to provide a special form of intermediate armrest means for use
between adjacent seating units where there will be a separate,
movable armrest member for each side of the unit and resulting
individual armrest adjustability for each person to be seated in
the adjacent seating units.
It may also be considered an object of the present invention to
provide an armrest-divider unit for use between adjacent seats,
where there is a small snack tray, or glass holding tray,
incorporated into the upper part of the framing, along with the
opposing, movable and adjustable armrest sections at each side of
the unit.
In a broad embodiment, the present invention provides an adjustable
armrest means for use between adjacent seating units in a multiple
seat arrangement, which comprises in combination, fixed position
armrest support framing that is attachable to adjacent seating
units and will extend upwardly between them, a movable armrest
section including a longitudinal cap portion positioned each side
of said support framing, with each such section being hingedly
connected to said support framing from its lower portion to thereby
permit arcuate movement for the upper cap portion of each armrest
section and individual adjustability for the positioning of each
armrest cap portion for each seat occupant on each side of the
armrest support framing.
Preferably, each movable armrest section will have adjustable
latching or catch means which will permit its adjustable fixed
positioning. For example, a movable member may have protruding
catch means to selectively engage any one of a series of spaced
recesses to thus provide different transverse positions and the
latching means can, in turn, be operated from a suitable
push-button or lift member, which is provided on the exterior of
the movable armrest section.
The entire armrest unit may be fixedly attached to the seat framing
so as to be positioned between adjacent seating units; however, an
optional arrangement may provide for a removable or demountable
type of armrest means where the armrest unit will be detachably
mounted in the manner of present forms of "stab-in" armrest units.
The removability feature provides for easy relacement or repair of
an entire armrest assembly as well as permit removability in the
event that a seat occupant desires to remove the assembly and
recline over a two-seat area. In the event of a stab-in or
removable mounting arrangement, there may be means provided to use
the conventional "slave" cable means such as are presently in use
in connection with present and prior forms of removable armrest
constructions.
An armrest assembly of the present type may also incorporate a
snack tray or drink holding tray, such as hereinbefore suggested,
with the tray means being provided in the upper portion of the
armrest assembly. Where there is space for a wide armrest unit, it
may be possible to provide a tray which is exposed and useful at
all times. However, where space may be somewhat limited, there may
be provided a snack tray which is maintained below the level of the
armrest cap means for each of the proposed adjustable and movable
armrest sections at each side of the unit requiring that each of
the adjacent seat occupants adjust the armrest sections into
positions toward themselves such that the upper snack tray will be
exposed and useful for the placement of drinks, cigarettes, or
other articles.
Still other advantages and variations in design and construction of
the present special armrest unit will be apparent by reference to
the accompanying drawing and the following description thereof.
FIG. 1 of the drawing is an isometric type of view indicating the
placement of the present form of improved adjustable armrest unit
between adjacent seats, such as between passenger seats in a
multiple seat vehicle arrangement.
FIG. 2 of the drawing is a sectional elevational view through one
embodiment of adjustable armrest unit providing for in-and-out,
transverse movement for each of a pair of armrest members.
FIG. 3 of the drawing is a longitudinal sectional elevational view
through the armrest unit of FIG. 2, as indicated by the lines 3--3
in FIG. 2.
FIG. 4 of the drawing is a partial sectional view indicating one
form of latching arrangement to provide adjustable fixed
positioning for each of the movable armrest sections of the
unit.
FIG. 5 of the drawing indicates diagrammatically how the entire
armrest assembly may be removably held in place between adjacent
seating units and, additionally, indicates diagrammatically how
push-button means and a short cable section may be combined with
the armrest assembly to, in turn, engage additional push-button
operated cable means to effect seat back adjustment.
Referring now particularly to FIG. 1 of the drawing, there is
indicated the placement of an armrest assembly 1 intermediately
between adjacent seating units such as 2 and 3, with the armrest
unit 1 being provided with fixed position end portions 4 and 5 as
part of the armrest support framing and movable side armrest
sections 6 and 7 providing suitable upper cap portions to serve as
the actual arm supporting portions for the occupants of the
adjacent seats. As will be described hereinafter, each of the
armrest sections 6 and 7 will be adjustable transversely by moving
through an arcuate path so that they may individually accommodate
each of the passengers in the adjacent seats.
With particular reference to FIGS. 2 and 3 of the drawing, there is
indicated that each of the movable armrest sections 6 and 7 will
have upper cap portions such as 8 and 9 as well as leg members,
such as 10 and 11, which will carry down to the support pin means
12 and 13, which in turn will be supported from the lower framing
of the armrest assembly. As best shown in the FIG. 3 longitudinal
section, the fixed end portions 4 and 5 of the support assembly may
comprise a plurality of interconnected plates in order to provide
structural rigidity. Specifically, the forward end section 4 is
indicated as comprising a pair of spaced plates 14 and 15 with
flanged edge portions to abut against and join with a peripheral
band member 16. There is also indicated the utilization of a front
trim plate such as 17 which will fit over the band member 16 to
provide a suitable trim or finish piece for the front portion of
the assembly. The rearward fixed section 5 is, in the present
embodiment, indicated as being formed of spaced plates 18 and 19,
each of which have flanged portions to engage a top and side
encompassing band 20 which is, in turn, encompassed at least in
part by trim piece 21. There is also indicated the use of a special
V-form of trim 22 to serve as the rearward portion of the armrest
assembly in a manner which will generally conform with the adjacent
sloping seat back portions of the seating units 2 and 3 (as best
indicated in FIG. 1).
It is to be understood that the end sections 4 and 5 may be
fabricated of metal and/or plastics in a variety of ways and it is
not intended to limit the present invention to any one set of
materials or to any one construction and assembly arrangement. The
present drawing is merely suggestive of one method construction and
arrangement for the support framing. In order to provide rigidity
for the entire armrest support framing, there are also utilized
longitudinal tie members between the end sections along both the
upper and lower portions of the unit. For example, as best shown in
FIG. 2 of the drawing, there are spaced lower U-shaped tie members
23 and 24 which may be attached to the end plate 15 by clip angles
25. Similarly, as indicated in FIG. 3, there may be clip angles 26
to attach the other ends of the longitudinal members 23 and 24 to
the vertical plate 18 of end framing 5.
Extending longitudinally along the upper portion of support
framing, there is indicated the placement of a tray form of beam or
tie member 27 to be used for connecting the upper end portions of
the spaced apart end frame sections 4 and 5. The tray form of
member 27 may be attached to the interior end plate 15 by clip
angle means 28 while at the opposing end a clip angle 29 will
provide attachment of the tray means 27 to the interior vertical
end plate member 18. Again, it is to be noted that various types of
struts or longitudinal tie means may be utilized to effect the
attachment of the end sections 4 and 5 into a substantially rigid
support framing and the construction and assembly of the adjustable
armrest unit should not be limited to the particular simplified
embodiment being illustrated and described in the present
application.
Various pivot and hinge means may also be provided for making a
hinged connection between leg support members 10 and 11 to the
lower support framing; however, a preferred construction will
provide for a simple hinged type of connection between the lower
portions of each of the adjustable armrest sections 6 and 7 with
respect to the support framing such that the opposing and separate
armrest sections may be moved independently and transversely toward
each adjacent seating unit to permit each seat occupant to have
individual adjustability as to the in-and-out positioning of their
particular armrest section. The present embodiment indicates that
the spaced leg members 10 and 11 will connect to the bolt or pin
means at 12 and 13; however, again, it is to be noted that separate
support means and separate pin means may be provided for each of
the individual adjustable armrest sections 6 and 7 where it is
deemed desirable to provide separate pivoting or hinging
arrangements for the separate pairs of support leg means. In the
present instance the drawing indicates the use of two plate means
30 extending between the longitudinal lower strut members 23 and 24
and each of the plates 30 in turn support upwardly extending spaced
bracket means 31 which will hold the pin members 12 and 13. Each of
the latter is also indicated as having sufficient length such that
the respective leg members 10 and 11 will be spaced apart a
sufficient distance to provide for spring means 32 between each of
the adjacent pivoting members, whereby the springs can provide for
the urging of each of the leg members and the accompanying separate
and opposing armrest cap sections 8 and 9 into a "closed"
position.
The operation of the movable armrest sections is best illustrated
by reference to FIG. 2 of the drawing where it will be noted that
both of the movable sections 6 and 7 are free to move in a
transverse arcuate manner (as shown by the dotted line positions)
by pivoting about their respective lower hinged connections to the
support framing. The armrest sections of FIGS. 2 and 3 with slight
spring biasing from the spring means 32 will assume a desired
position from a frictional engagement with a seat occupant's arm
resting on the upper cap portions 8 and 9. However, as will be
described hereinafter, there may be actual fixed adjustment
positions from suitable latching means whereby seat occupant can
set his adjacent armrest section to a desired position which will
be maintained until the latching mechanism is released and the
armrest section pushed or pulled to a different position.
FIG. 2 of the drawing also indicates the use of a pliable fabric,
plastic or other upholstry type of material along each side portion
of the armrest assembly so as to provide a finish or trim which
will hide the interior of the supporting frame and the movable
supporting leg members, etc. Specifically, there is indicated the
use of flexible side pieces 33 and 34, the upper portions of which
are attached to longitudinal bar sections at 35, extending between
arm members 10, and to the bar member 36 which extends between arm
members 11. At the lower side portions of the unit the flexible
side pieces 33 and 34 can be attached to the sides of the
respective U-shaped tie beams 23 and 24. Also, as indicated by the
dashed line positions, the side pieces will move along with the
movable armrest cap sections 8 and 9 as the latter are adjusted
outwardly to suit a passenger's comfort.
Referring now to FIG. 4 of the drawing, there is indicated a curved
perforate bar member 37 as being mounted below the tray member 27
to accommodate a movable latch member 38 which is attached to a pin
or rod means 39 extending between arm members 10. In the particular
arrangement shown, the bar member 38 is attached to and pivots over
the top of the pin member 39 so that its interior end may move
vertically up and down responsive to a lifting or pushing of the
exterior end portion 40. The interior end portion of bar member 38
is also indicated as having a raised portion 41 which can engage
the various openings or notches, such as 42, in the fixed curved
member 37. In the present drawing, the raised portion 41 is
indicated as being engaged with the innermost recess opening 42
such that the cap member 8 is retained in a "closed" position;
however, as indicated by the dashed lines 38' for member 38, when
external end portion 40 is lifted slightly, there is a pivoting of
bar member 38 over the top of pin 39 such that raised portion 41
will become disengaged from curved member 37 under the tray 27 and
the movable armrest section together with its cap portion 8 can
pivot outwardly to assume a position which will be closer to the
occupant in the adjacent seat. In addition, a spring 43 is provided
around the pin member 39 with one end portion engaging the leg 10
and the other end against the back of bar member 38 so that there
is a continuous spring biasing of the latter member in an upward
direction against the curved plate member 37 and such that the
raised catch portion 41 will automatically be urged upwardly to
effect engaged positionings with each successive hole 42 in bar
member 37. However, by the lifting of end portion 40 and the
positioning of the cap portion 8 to the approximate desired
location, the raised portion 41 can engage a hole 42 nearest the
desired position and there will be the subsequent holding of the
entire movable armrest section in this desired location.
FIG. 4 also shows the use of a recessed trim member or escutcheon
plate 44 which is attached to the longitudinal tie bar member 35
which extends between the spaced leg members 10. The trim member 44
should be sized and designed to permit a passenger to insert a
thumb or finger behind the end knob portion 40 on bar 38 such that
there may be easy manipulation and operation of the adjustment
means for the movable armrest section. It is also to be noted that
FIG. 4 of the drawing only illustrates a locking mechanism for one
adjustable arm section for one side of the assembly, but that a
similar arrangement and operation will be provided for the opposing
movable arm section with cap member 9 such that there may be
adjustability to a desired fixed positioning for such cap member.
It is also to be noted that varying types of latching mechanisms
may be utilized and it is not intended to limit the present
invention to the specific form illustrated in FIG. 4. It is,
however, desired that any latching mechanism be readily adjusted by
the seat occupant and that it be spring biased to assist in
providing ease of locking and for maintaining a desired fixed
location.
In FIG. 5 of the drawing, there is indicated diagrammatically a
non-attached, "stab-in" positioning of the entire armrest assembly
1 with respect to the seat framing such that the unit may be
readily inserted and removed from its positioning intermmediate
adjacent seats in a multiple seating arrangement. The drawing is
diagrammatic in indicating the use of depending bars or leg members
45 for insertion into suitable socket means 46 maintained as a part
of the seat framing, and there is no intent to limit the detachable
mounting arrangement to any one design or construction. FIG. 5 also
illustrates the fact that there may be push-button control means
for seat back adjustment, such as at 47, mounted in a forward
portion of the armrest assembly. Actually, there may be a pair of
push-button means 47 mounted in the assembly such that each of the
adjacent passengers will have individual push-button operations for
their individual seat backs. Where there is a disengageable type of
mounting arrangement for the armrest assembly, there can also be a
seat back operating arrangement where the push-button means 47 and
a short cable means 48 will terminate in a movable pin or button
means at 49, and the latter will be mounted to be in alignment with
another push-button means at 50 to operate cable means 51 that is
mounted in the seat unit framing and which will extend to the seat
back adjusting valve or other adjustment mechanism.
It will be obvious that various structural modifications may be
made in connection with the armrest supports framing, as
hereinbefore noted, and further variations made with respect to the
shape and configuration of the movable armrest cap sections, such
as 8 and 9, as well as with respect to the lower hinging means and
the supporting leg means connective with the cap portion. Various
types of construction and trim materials may also be utilized and
again it is not intended to be limiting with respect to the use of
any one type of material or combination of materials for any one
section of the unit. For example, the movable armrest cap members 8
and 9 may well be formed of a self-skinning type of rigid foam
material such that there is a washable finish with good
wearability, as well as being of a lightweight type of material.
Trim portions may be of chrome finished metal, aluminum, painted
metal, etc., or, optionally, there may be any one of various types
of plastic materials utilized for the entire section or for a
finish over a metal section.
