  • Patent number: 5675875
    Abstract: An adjustable break away attachment have a base attached to one item and a disengageable attachment member held to the base by restraining pins. When sufficient tensile force is applied to the attachment member it will break away from its base pins. The attachment member has several notches formed in joined tapered surfaces where each notch engages a pin on its flattened side surface. By changing the pins, number, size, material or placement on the base the amount of break away tensile force needed to dislodge the attachment member can be varied. This invention has a great many applications, including but not limited to, a break away attachment for a football helmet's face mask.
