This invention relates to an interior a~~~to~nctive safety barrier that
separates the driver from passengers and other cargo in the rear seat and the
right
s front seat. it is particularly suited to protecting taxicab drivers from
attacks by
passengers.
~A~~CGR~3lJ~L~ ~~ ThIE il~l~Et~TI~P~
The current in~°entio~~ provides an innr~vative solution for
protecting
taxicab drivers. The ~JS department of labor identified cab and limousine
drivers as
~o the occupation with the highest homicide rate in the !J~ - 4..4 hosr~icides
per year per
1 gg,g~t3 workers. The currenf invention provides the : ~evessary separa~ior~
between
drivers and passengers v~ithout offending the fare-paying ~storr~er. Miler
typical
shields as described by patents ~a~~adia~v patent 1,19,31 and Canadian patent
2,g11,2g~ which vc~lly separate the front seat from the r ear seat, leave the
passenger
~s feeling like he is a prisoner in a p~.~lice car. U~lith the present
inventions a passenger
in the rear right seat, which is the seat of first choice, has no shield in
front of him,
and no feeling of confiner~nent. ~~rom the: fare-paying-customer's
perspective, it is
the driver who is behind thv shield.
shields, which form ~ corr~piete partition across the vehicle, separating
~o the front seat from the rear seat, also form a cornplete~ barrier to air
circ~slation. This
inhibits air conditioning, heating arid ventilation equipment located in the
dash area
frorr~ effs'ectively controlling temperature aid providing ventilation to the
rear seat
area.

These problems have been addressed by ~S Patent 4,509,7~~ which
advances the state of the art through a safety arrangement consisting of an
adjustable driver's seat, a side partition fixed to the floor arid top of the
car body, a
bade partition attached to the top of the car body and 3~itting into a
vertical groove in
~ the side shield that allows a certain:. amount: of vertical ad~usvment
relative ~:o the side
shield. Each of the partition members has a hallow-~~rvall construction in the
lover
portion, which is aligned with the upper clear Plexigla s. °~his
introduces a new set of
problems, which the carrel ~t invention solv~a.
l~S Patent ~,5flg,7~~ incorpcarates a seat as part of the arrangement.
~.o The seat has a vertical back, a long side lever to control the recline,
and attachment
mountings for the rear shield. These are non-standard features of typical
automotive
seats, which r~-ieai~s that a special seat is necessary to make the ac
rangement
functional. The embodiment as describes hereinafter care accommodate standard
bucket or split-bench seats found in the foil sire ~mE.rican :yodel cars
typically used
~s fear taxicabs. This contrsbi.~tes to the cost effectiveness of the
solution.
It is ~reil known in the autorr.~otive industry, that passenger knee-to-hip
room has a mayor impact on passenger comfort. Even the loss of one inch in
knee-
to-hip room, has a significant ii~pacf on passenger ~comfoft. The rea~~ shield
of L~S
Fatent 4,~Og,7~~ has a hollow gall design, veratiiatioi a apes=~-ures v9rith
meri~bers offset
2o from both sides of the wail, and rnountiog brackets os~hich vur-ther offset
the wall
behind the driver's seat, such what the critical knee-~°~o-hip rs~om
irl the seating
position rear of the driver, is significantly reduced. The embodiment as
described
hereinafter has a sheet metal lov~eer rear shield w~rhich obtains its
stiffness and
CA 02424286 2003-04-O1
strength in formed edges that proe~eed for~~ard from t:he position that passes
behind
the driver's seat. The only loss irr 9~nee-t~~-hip room is the thickness of
the sheet
metal, which is negligible.
!t is well known in the a~~t~~motivv industry, that typical autorraotive
s driver's seats reguire the seat beak to be inclined for ;roper driver
c~ar~fort. The
angle of inclination most comfortable for drivers of The ~Orrrerioan built
full size mars
typically used for taxi shields, is approximately 1~ degrees ~~rom vertical.
The actual
angle most comfortable for a specific driver varies rrvith driver preference.
The
arrangement in t~S ~atenf 4.,~Og, ~'~ situates the driver's seat and the rear
partition
xo in the vertical position, vuhich is uncomfortable and results in driver
fatigue, and
provides for no adjustment of easy bacl~ angle while stiff! rnaintainir~g the
rear- shield
engaged with the side shield. ~,ls~o, where is no ~~ore/att ad~ustr~ent of
t~~e driver seat
while still maintaining the rear- shield engaged vuith The side shield. The
ernbodir~ent
as described hereinafter positions the rear shield v~:ight against the back of
the
~s driver's seat, and then is shaped to be approxima;:ely vertical ire the
trarsparer~.t
ripper portion vrrhich extends above the driver's seat. The driver can adjust
his seat
forelaftq up/dc~v~n and angle of recline, while the rear shield moves ~rith
his seat. in a
particular embodiment of the invention, the rear shield has a side flarsge
that
overlaps the side shield assembly, so they the security barrier is maintained
Through
2o a range of norms! driver seat positions. ire another errabodiments the side
shield and
rear shield are fixedly attached with guick disconnect fasteners, and the side
si~rield
is shaped to move with the ; ear- shield through a rrorr~ai range of driver
seat
CA 02424286 2003-04-O1
4
positions. The roar shield has arv upper and lower portion, vrhich overlap, so
that the
total vertical height of the rear shield can be adjusted to accommodate
different cars.
current ~ar~adian and ~,mc:rican ~'ederai I~lotor safety ~ta~~dards
reg~aire front car seats to act as a~~ er~erg~~ absorber if rear passenger,
are thrown
into them in a frontal collision. ~~ patent 4;~09,~88 describes a rear shield,
which is
fixed to the ceiling and to the lower portion of the dr°iver seat. ~~
he shield forms a
rigid barrier due to its attachment at the ~;eiling and the bottorr~ of the
driver seat.
The embodiment as described hereinafter provides energy absorption in accident
situations by piggybacking on the energy :~bsorbir~g tratur es that are
:~esigr~rd into
xo every front automotive car sea's. E~y rnocnting 'the rear shi~:ld to bhe
seat back, and
not rigidly mounting it into the car, the shield exhibits similar forbe-
deflection energy
absorption as the driver seat with r°~o shield. ~orr~all~°, it ~
a ~-ror~tal collision, energy is
absorbed by plastic deforrr~ation og th~ seat structure, grad by the seat
padding, thus
protecting rear passengers. ~lith the re~~r shield installed only to the seat
back,
~ ener°gy is absorbed by the plastic deformation of the seat structure,
and t1 ~e padding
on the shield.
LJS Patent 4,~~?9,788 describes a rear shield releasably attached at the
top of the car body, and at the side shield. l~ihen released, the rear shield
and the
driver seat can be reclined into a comfoa'~le couch duri~ig rest periods. In
pPeferred
2o embodiments of the invention, the driver seat can lie reclined with the
rear shield
attached ~°vithout releasing any fasteners or latches.
!~S latent ,5897,88 descrilaes a side shield that is fixedly attached to
the floor and ceiling of the automobile. This creates a concern should the
driver
CA 02424286 2003-04-O1
wish to egress fr om the vehicle through the right front door, as may be
necessary if
the driver's door becomes ~anrr~ed as in an acciderRt. In one ernbodirr~ent of
the
invention, the side shield is siideably attached to the vehicle floor anew
vehicle roof,
such that it ray be slid rear~rard to open, ~4 latching rr~echanism that is
accessible
~ oniy to the driver secures it in a plurality of closed positions°. In
an aiternate
embodiment of the invention, vhe side shield is atts,ched ~o the rear shield
with a
quick disconnect fastening arrangerr~3ent. 1°he side shield can be
quickly and easily
rer~roved for driver egress.
