Load Distribution Garment
A load distribution garment for use under a ballistic vest includes a shirt to be worn under the vest. The shirt has interface grips on its outside to engage the inside of the vest and help to transfer vertical load of the vest to the shirt. The shirt has tightenable straps that help to keep the shirt snub on the user's torso. As a result, some load of the vest is transferred to the user's torso, including the core, rather than being carried solely on the shoulders and collarbone area.
1 . Apparatus comprising
a ballistic vest configured to be worn by a user, the vest having an inside vest surface; and
a load distribution garment configured to be worn by the user under the vest, the load distribution garment having an outside garment surface;
the load distribution garment including a shirt having an outside surface, the outside surface of the shirt forming a first portion of the outside garment surface of the load distribution garment;
the load distribution garment including interface grips located on the outside surface of the shirt, the interface grips having a significantly higher coefficient of friction than the shirt, the interface grips forming a second portion of the outside garment surface of the load distribution garment;
the inside surface of the vest engaging the interface grips on the outside garment surface of the load distribution garment, the engagement of the inside vest surface with the interface grips resisting movement of the vest relative to the load distribution garment.
2 . Apparatus as set forth in claim 1 wherein the locations of the interface grips on the outside of the shirt are selected to enable vertically downward load of the vest to be transferred to the shirt at one or more locations other than the user's shoulders and collarbone area.
3 . Apparatus as set forth in claim 2 further including tightenable straps on the shirt that help to keep the shirt snug on the user's torso thereby to help ensure that loads placed on the shirt by the vest are transferred to the user's torso.
4 . Apparatus as set forth in claim 3 wherein the tightenable straps include posture control straps that extend rearward over the shoulders of the shirt and down the back of the shirt and have lower ends that are securable to the front of the shirt thereby to pull back on the shoulders of the user.
5 . Apparatus as set forth in claim 4 wherein the tightenable straps include waist straps that extend laterally from the back of the shirt around the sides of the shirt and have ends that are securable to the front of the shirt to keep the shirt snug on the waist portion of the user's torso thereby to help transfer loads placed on the shirt by the vest, to the user's torso.
6 . Apparatus as set forth in claim 3 wherein the straps extend through channels on the shirt.
7 . A load distribution garment configured to be worn under a ballistic vest by a user, the vest having an inside vest surface, the load distribution garment comprising:
a shirt made of a shirting material, the shirt having an outside surface;
interface grips located on the outside surface of the shirt, the interface grips having a significantly higher coefficient of friction than the shirt, the interface grips forming a portion of the outside surface of the shirt; and
the inside surface of the vest engaging the interface grips on the outside surface of the shirt, the engagement of the inside vest surface with the interface grips resisting movement of the vest relative to the shirt.
8 . Apparatus as set forth in claim 7 wherein the locations of the interface grips are selected to enable vertically downward load of the vest to be transferred to the shirt at one or more locations other than the user's shoulders and collarbone area.
9 . Apparatus as set forth in claim 8 further including tightenable straps on the shirt that help to keep the shirt snug on the user's torso thereby to help ensure that loads placed on the shirt by the vest are transferred to the user's torso.
10 . Apparatus as set forth in claim 9 wherein the tightenable straps include posture control straps that extend rearward over the shoulders of the shirt and down the back of the shirt and have lower ends that are securable to the front of the shirt thereby to pull back on the shoulders of the user.
11 . Apparatus as set forth in claim 10 wherein the tightenable straps include waist straps that extend laterally from the back of the shirt around the sides of the shirt and have ends that are securable to the front of the shirt to keep the shirt snug on the waist portion of the user's torso thereby to help transfer loads placed on the shirt by the vest, to the user's torso.
12 . Apparatus as set forth in claim 9 wherein the straps extend through channels on the shirt.
