Description
BACKGROUND OF THE INVENTION
The present invention relates to a device for preventing neck
injury. More specifically, the present invention relates to an
elastic strap for preventing neck injury during the employment of a
head piece and a body harness.
In contact sports such as football, a great deal of protection
equipment for the player is highly desirable. Nevertheless, even
then, the player is often still subject or susceptible to various
injuries. For example, football players with more and more
regularity are literally using their heads to block and tackle
opponents since the modern day helmets readily absorb shock.
However, such contact and collision cause the head to violently
snap if the opponent is not hit directly head-on. One of the most
potential serious injuries which can occur is the flexion cervical
sprain which occurs when the head is snapped forward. Due to the
propensity for fracture-dislocation of the neck, this injury is
life threatening and often is fatal.
Present protection equipment is not satisfactory. Heretofore, the
best preventive measure was to have the individual use reverse neck
rolls. However, the undue limitation of motion as well as
inconvenience to the player makes this piece of equipment
unsatisfactory.
SUMMARY OF THE INVENTION
It is therefore, an object of the present invention to provide an
apparatus for preventing neck injuries.
It is another object of the present invention to provide an
apparatus for preventing neck injuries, as above, which limit the
forward motion of an individual's head.
It is a further object of the present invention to provide an
apparatus for preventing neck injuries, as above, in which an
elastic strap is connected at one end to a body harness and the
other end to a helmet.
In general, an apparatus for preventing neck injury during the
employment of a head piece and a body harness device has an elastic
strap with fastening members thereon. The head piece is provided
with a securing member as is the body harness device and the strap
engages these securing members and thereby limits the forward
movement of the head piece as upon impact.
A preferred embodiment of the present invention is described in
detail without attempting to discuss all of the various
modifications in which the invention might be embodied, the
invention being measured by the appended claims and not by the
details of the specification.

DESCRIPTION OF THE PREFERRED EMBODIMENT
An apparatus for preventing neck injury according to the concepts
of the present invention is generally indicated by the numeral 10.
Basically, the concept relates to an elastic type device which is
attached to the body and to the head of a person so that the
forward movement of the head upon impact is limited. The device
can, of course, be utilized in any situation wherein the human head
is subjected to snapping forces and finds a preferred use in
contact or collision sports, such as workouts on a trampoline and
in football.
As shown, apparatus 10 is generally formed of an elastic strap 11
made according to conventional methods of conventional material
such as cotton, nylon, rayon or the like and contains elastic
material such as rubber to impart elasticity.
Fastening members, generally indicated by the numeral 12, usually
reside in the end portions 13 of strap 11 and may be adhesive
material or a mechanical item. Desirably, fastening members 12 are
mechanical fasteners such as button clips 14. As best seen in FIG.
2, the button clips may be either male or female and preferably
exist in a plurality in order to permit the use of the strap in a
variety of situations. In the embodiment disclosed, the elastic
strap measures 1 1/2 inches by 9 1/4 inches and the button
fasteners which are of the 1/4 inch eyelet type are placed about 1
1/4 inches, 1 1/4 inches, 4 inches and 1 1/4 inches apart to permit
employment in a variety of situations. Other locations, number of
button clips as well as type of fasteners can, of course, be
utilized in the present invention, as, e.g., Velcro fasteners,
(T.M. of American Velcro, Inc.)
Turning to FIGS. 3 and 4, elastic strap 11 can be used in
association with a head piece generally indicated by the numeral 21
and a body harness generally indicated by the numeral 31.
Generally, the head piece may simply be a belt of elastic material
around the head. More elaborate structures include a helmet 22 of
the type used in football. Preferably, the helmet as shown in FIG.
4, has at least a securing member, generally indicated by the
numeral 23, such as a small button clip for engagement with one of
the strap button clips. Such securing member may be located about 2
1/2 inches above the back lip 24 of the helmet. Moreover, the
helmet may have a plurality of securing members and may be of any
conventional type as may be the fastening members 12 of the strap.
Body harness 31 may simply be a belt wrapped around the chest of an
individual, preferably below the arms, a packing harness or the
like. In the preferred embodiment of the present invention, it is a
conventional football shoulder pad assembly, generally indicated by
the numeral 35. The shoulder pads have back protection vests 36 to
protect the upper portion of an individual's back and are secured
together as by strings 37 to maintain the shoulder pads in proper
position. As with the helmet, any securing member, generally
indicated by the numeral 38, may be used such as button clips which
are attached to the central portion of the back of the shoulder
pads. Also, a plurality of such securement clips may be
utilized.
In actual use, once the shoulder pads and helmet have been
assembled, strap 11 is attached to securing members 23 and 38 of
the helmet and shoulder pads through fastening members 12 with the
head located in a normal upright position as shown in FIG. 4.
Because the strap runs from the back of the individual's head to
the upper portion of the midback, normal side to side movement of
the head as well as turning of the head is still quite freely
permitted. Due to the plurality of fastening members on the strap,
a single strap can fit a number of individuals as well as helmets
and shoulders pads which have varying locations of securing members
23 and 38. Since the strap is elastic, slight forward and downward
movement of the head is permitted against the elasticity of the
strap. Great forward movement normally caused during rough contact
or a collision which would normally cause a flexion cervical sprain
is prevented since elongation of the strap is short, approximately
40 - 75 percent. Moreover, the shock upon impact is absorbed by the
strap which retards free forward movement of the head as well as
reducing the speed of such head movement. Should an individual's
head reach the elongation extent of the elastic strap, the
remaining forward motion energy of the head will be absorbed by the
helmet instead of being transferred to the highly susceptible
neck.
Elastic straps made according to the concept of the present
invention according to the physical embodiment set forth above have
been tested in seventeen football practice sessions by 22 players
to establish its feasibility. A breakdown of the players' positions
revealed that nine were defensive linemen, five were defensive
backs, four were offensive linemen and the remaining four were
offensive backs. The straps were snapped into place onto the
helmets and should pads with the player's head in an upright
position and were worn during all practice sessions. Eight of the
22 involved players had a previous history of neck sprains and
burners or pulled muscles. During the entire testing period, not
one neck sprain, burner or other neck ailment, was reported.
Moreover, the elastic straps were well accepted by both players and
the coaches and interfered very little with normal movement of the
head.
Although only a single strap need be used, a plurality of straps
may be attached to the back of the headpiece 21 and the body
harness 31.
Moreover, according to another embodiment of the invention, not
shown, straps 11 may be mounted on each side of a person's head
either alone or in combination with a back strap to prevent neck
injuries caused by lateral movement. Accordingly, the headpiece
such as a football helmet and the body harness such as a pair of
shoulder pads may contain side or laterally located securing
members to permit the installation of lateral straps so as to
prevent burners and the like when a person's head is snapped or
jerked sideways. The strap may have a plurality of fastening
members and the headpiece and the body harness may have a plurality
of securing members as set forth above.
As apparent to one skilled in the art, modifications to the
preferred embodiment can be made without departing from the spirit
of the invention herein disclosed and claimed, the scope of the
invention being limited solely by the scope of the attached
claims.
