Patent ID: 8479434

Claim:
An accessory interface system for coupling an accessory to a mount, comprising: a first module of the accessory interface system adapted to be coupled to a first equipment item mount, said first module section comprises a first shear coupling section and a substantially non-shear coupling section, said substantially non-shear coupling section is adapted to couple said first module to said first equipment item mount; and a second module of the accessory interface system adapted to be coupled to said first module, said second module having a plurality of mounting surfaces, wherein said second module further comprises a second shear coupling section adapted to be coupled with said first shear coupling section, said first shear coupling section and said second shear coupling section adapted to maintain coupling and relative position to each other up to a first force is being applied to said first shear coupling section or said second shear coupling section, said coupling between said first shear coupling section and said second shear coupling section being adapted to shear when at least a second force applied to said first shear coupling section or said second shear coupling section, said first force being approximately a 20G load or greater.
