Ballistic package for soft body armor
View Patent ↗A ballistic performance and trauma reduction system for soft body armor including a solid plastic sheet cut into multiple sections of geometric designs which overlap and are stitched to one or more layers of woven or non-woven ballistic fabric contained within a ballistic package of the soft body armor. Energy is transmitted through the ballistic sheets to the plastic sheet improving ballistic performance and reducing trauma to the wearer's body, resulting in safer, thinner and lighter armor.
1. A ballistic panel for use in ballistic apparel comprising:
a plurality of layers of ballistic material; and
a plastic sheet comprising multiple sections partially overlapping one another, wherein the plastic sheet is attached to at least one layer of ballistic material by stitching along overlapping portions and a perimeter of the plastic sheet;
wherein the plastic sheet extends laterally across substantially the entire width of the panel;
the sheet comprising at least three plastic sections arranged laterally adjacent to each other across the width of the panel with each one of the sections extending laterally for about one third of the width of the panel, each two adjacent sections overlapping each other only along their respective edge portions, a substantial majority of the surface area of each section not overlapping any part of any other section.
2. The panel of claim 1 wherein the plastic sheet has between three and six sections.
3. The panel of claim 1 wherein the plastic sheet has two rows of stitching along the overlapping portions.
4. The panel of claim 1 wherein the plastic sheet is a self-reinforced polypropylene composite material.
5. A panel as set forth in claim 1 wherein the width of the area of overlap of any two adjacent sections, as measured in a direction extending across the width of the panel, is in the range of up to about 10% of the total width of the sheet.
6. A panel as set forth in claim 5 wherein the width of the area of overlap of any two adjacent sections, as measured in a direction extending across the width of the panel, is in the range of up to about 20% of the section width of the any two adjacent sections.
7. A panel as set forth in claim 6 wherein the width of the area of overlap of any two adjacent sections, as measured in a direction extending across the width of the panel, is in the range of about one to three inches.
