Neck collar
A neck collar interfacing with a lower edge of a helmet of a wearer. The collar includes a pad and a shell. The pad is formed of a closed-cell foam material and forms a loop to be secured about the neck of the wearer. A plurality of shell components are secured to portions of the upper face of the pad. The shell is more rigid than the pad to spread the energy of impact with a lower edge of the helmet over a larger region of the pad. The shell and pad each include a chest portion having a split for opening the pad for putting the collar on and taking it off. The shell components are discontinuous at at least one lateral portion of the pad to allow flexibility of the pad for separation of the pad at the split.
1. A neck collar for use by a person wearing a helmet having a lower edge, the neck collar comprising:
a pad forming at least a partial loop, the pad being of compressible material, the pad having an upper face and a lower face, the lower face positioned for opposing the person when worn around a neck of the person; and
a shell overlying at least a portion of the upper face of the pad, the shell being formed of a material more rigid than the pad and being situated for at least intermittent contact with a lower edge of the helmet upon use, the shell including a rear portion and first and second chest portions;
wherein the shell defines a first gap between the rear portion and the first chest portion and adapted to be positioned over a first lateral shoulder region of the person such that the shell does not cover a first portion of the pad along a first small region of the pad, thus allowing the first chest portion of the neck collar to move laterally upon flexure of the small region of the pad that is not overlaid with the shell;
wherein the shell defines a second gap between the rear portion and the second chest portion and adapted to be positioned over a second lateral shoulder region of the person such that the shell does not cover a second portion of the pad along a second small region of the pad, thus allowing the second chest portion of the neck collar to move laterally upon flexure of the second small region of the pad that is not overlaid with the shell;
wherein no portion of the shell spans the first gap to connect the first chest portion to the rear portion and no portion of the shell spans the second gap to connect the second chest portion to the rear portion.
2. The neck collar of claim 1 , wherein the chest shell portion is split between a right side and a left side such that the right side and left side are separable from each other for donning and doffing the neck collar.
3. The neck collar of claim 2 , wherein the right side and left side are separable from each other for donning and doffing the neck collar.
4. The neck collar of claim 3 , wherein the shell includes a closure tab between the right side and the left side of the chest portion of the shell.
5. The neck collar of claim 3 , further comprising a liner disposed along the lower face of the pad and overlapping split between the left and right sides of the pad chest portion, the liner having a fastener to secure the right and left sides of the pad chest portion together.
6. The neck collar of claim 1 , further including a back support brace secured beneath the lower face of the pad at a rear portion of the pad, the back support brace adapted to extend down a portion of a back of shoulders of the person wearing the neck collar.
7. The neck collar of claim 6 , further comprising a rear strut between a lower portion of the back support brace and the rear portion of the pad, the rear strut being flexible and energy absorbing upon impact of the neck collar with an edge of the helmet.
8. The neck collar of claim 7 , wherein the rear strut is adjustable to change a relative position of the back support brace to a chest portion of the pad.
9. The neck collar of claim 6 , further comprising a harness for holding the pad to the person, the harness having a strap adapted to extend under at least one arm of the person.
10. The neck collar of claim 1 , wherein the compressible material is elastic within its normal range of use.
11. The neck collar of claim 10 , wherein the compressible material is a closed-cell foam.
12. The neck collar of claim 1 , further comprising a liner disposed about most of the lower face of the pad and within inner sides of the pad.
13. The neck collar of claim 12 , wherein the liner comprises a molded EVA foam material.
14. The neck collar of claim 1 , wherein the pad includes a rear shoulder portion wider than a remainder of the pad for increased energy absorption upon impact with an edge of the helmet.
15. The neck collar of claim 1 , wherein the shell is plastic and is bonded to the pad over portions of an upper surface of the pad and over portions of sides of the pad.
16. A neck collar for use by a person wearing a helmet having a lower edge, the neck collar comprising:
a pad forming at least a partial loop, the pad being of compressible material, the pad having an upper face and a lower face, the lower face positioned for opposing the person when worn around a neck of the person; and
a shell overlying at least a portion of the upper face of the pad, the shell being formed of a material more rigid than the pad and being situated for at least intermittent contact with a lower edge of the helmet upon use;
wherein the pad includes a front, chest portion that is split with a right side and a left side that are separable from each other for donning and doffing the neck collar;
wherein the shell includes a shell rear portion and a shell chest portion overlying a pad chest portion, the shell chest portion being split with a right side and a left side that are separable from each other for donning and doffing the neck collar;
wherein the right side and left side of the chest portion are separate members from the shell rear portion and two gaps are defined between the shell rear portion and the right and left sides of the shell chest portion, respectively, such that the two gaps are adapted to be positioned over respective first and second lateral shoulder regions of the person and the shell does not cover any portion of the pad along small regions of the pad extending between the right and left sides of the shell chest portion and the shell rear portion and such that no portion of the shell connects the right and left sides of the shell chest portion to the shell rear portion, thus allowing the shell chest portion to move laterally upon flexure of the small regions of the pad that are not covered with the shell.
17. A neck collar for use by a person wearing a helmet having a lower edge, the neck collar comprising:
a pad forming at least a partial loop, the pad being of compressible material, the pad having an upper face and a lower face, the lower face positioned for opposing the person when worn around a neck of the person; and
a shell overlying at least a portion of the upper face of the pad, the shell being formed of a material more rigid than the pad and being situated for at least intermittent contact with a lower edge of the helmet upon use;
wherein the shell includes a rear shell portion and a chest shell portion, the rear shell portion being a separate member from the chest shell portions and a first gap being defined between a left side of the chest shell portion and the rear shell portion and a second gap being defined between the right side of the chest shell portion and the rear shell portion such that the shell does not cover portions of the pad spanning the first and second gaps from the chest shell portion to the rear shell portion, the first and second gaps are adapted to be positioned over first and second lateral shoulder regions of the person, thus allowing the chest shell portion of the neck collar to move laterally upon flexure of the portions of the pad spanning the first and second gaps from the chest shell portion to the rear shell portion.
