  • Knife-proof garment material with protruded texture
    Patent number: 5306532
    Abstract: A protective garment material is constructed with a matrix of cells with protrusions. These cells are linked with polygonal connecting plates, which have cuts at the corners to form a section of a complete frame for the protrusions. The linkage is formed with aligned semicylindrical flanges extended from the edges of the connecting plate and semicydrical grooves aligned in a different direction serving as sockets for the semicylindrical flanges from a neighboring connecting plate, so that any two neighboring plate can be rotated with respect to each other. The connecting plate also serves as a protective layer for the inner cell in the unprotruded area. The protrusions dirert any frontal thrust sidewise to prevent penetration.
