DET~b~ E~Ç5~ QN-~Q~ Q~ TS
Turning now descriptively to the draw.ings, in which
similar reference characters denote similar elements
throughout the several views, the Figures illustrate a
headrest extension 10 for a seat 12 of the type having an : :
existing built-in headrest 14 supported by a stanchion 16 ;~
extending upwardly from the top of a seat back l~ oE a seat
12. The headrest extension consists of a cushion 20 having a
body of relatively soft materlal and a mechanism 22 for
attaching the cushion 20 to the existing built-in headrest 14
so that when a person 24 sits .in the seat 12, the head 26 of
the person 24 can rest comfortably agalnst the cushion 20.
As bes shown in Figures l, 2 and 3, the attaching ~ ~
mechanism 22 includes a pair of belts 28 with each extending ~ ;
from an opposite side of the cushion 20. Hook and loop fabric ~ : :
fastener strips 30 are affixed to the distal ends of the belts ~:~
28 so that the distal ends can be attached to each other when
the belts 2 are wrapped around the existing built-in headrest
14. ~:
As shown in Figures 4, 6 and 7, the attaching mechanism
22 includes a C-shaped spring clamp member 32 affixed to the
rearward end of the cushion 20, which fits onto the existing ~ :
built-in headrest 14.
Figure 5 shows the attaching mechanism 22 including the
existing built-in headrest 14 having a vertical slot 34
proximate its forward end thereof and a flat bar 36 having a
5-

2~6830A
hooked end 38 affixed to the top rearward end of the cushion
20. The flat bar 36 will extend downwardly parallel with the
rearward end of the cushion 20 and Eit into the vertical slot
34 in the existing built-in headrest 14. A channel 40 may be
formed in the bottom end of the cushion 20. A shoulder-back
contoured extension member 42 has a top groove 44 which can be
attach~d to and extend downwardly from the channel 40 to aid
in helping a person 24 with back pain to sit more comfortably
in the seat 12.
A headrest extension 10, in Figures 6 and 7, further
includes the C-shaped spring clamp member 32 having a threaded
hole 46 therein. A threaded shank 48 is engagable within the
threaded hole 46, while a plVOt joint 50 i9 affixed to the
distal end of the threaded shank 48. A wavy circular:casing
52 is about the cushion 20, with the pivot joint:50 connected
to the rearward end of the cashing 52. A person 24 can adjust :~
the angle of the cushion 20 via the pivot joint 50 and can
adjust the distance of the cushion 20 from the existing
built-in headrest 14 by rotating the wavy circular casing 52,
there~y causing the threaded shank 4R to move inwardly and
outwardly in the threaded hole 46.
In Figures 8 and 8A the attaching mechanism 22 includes ~
a first L-shaped member 54, having a first leg 56 aEfixed to ~ ::
the rearward end of the cushion 20 and a second leg 58
extendiny therefrom. A second L-~haped member 60 has a first
leg 62~te1escopically engagable within the first leg 56 of the
first L-shaped member 54 and a second ley 64 extending

therefrom. ~t least one wing bolt 66 is threaded into the
first leg 56 of the first L-shaped member 54 and into the ~-
first leg 62 of the second L-shaped member 60 so as to retain
the second L-shaped member 60 to the first L-shaped member 54
to fit onto the sides of the existing buil~in headrest 14.
Figures 9 and 9A show the attaching mechanism 22 further
including a pair of flat pins 68 and 70. The Eirst flat pin
68 is mounted to the side of the second leg 58 of the Eirst
L-shaped member 54 and extends outwardly therefrom. The
second flat pin 70 is mounted to the side of the second leg 64 ;~
of the second L-shaped member 60 and extends outwardly
thererom. A pair of belts 72 and 74 are provided. The fixst
belt 72 has a slotted buckle end 76 which fits onto the first
flat pin 68~ The second belt 74 has a slotted buckle end 78 ~
which fits onto the second flat pin 70 so that the free ends ~ ;
of the belts 7~ and 74 can be wrapped around the existing
built-in headrest 14 and tied together at 80.
While certain novel features of this invention have been
shown and described and are pointed out in the annexed claims,
it wi11 be understood that varlous omissions, substitutions
and changes in the forms and details of the device illustra-ted
and in its operation can be made by those skilled in the art
without departing from the spirit of the invention.
