Abstract: A shock attenuating mounting bracket (30) for isolating a hardware component from shocks associated with an underlying structure includes a base (32) and a planar strip (34) coupled together. The base (32) is coupled to the underlying structure and the planar strip (34) is coupled to the hardware component. The planar strip has at least two bends (36,38) along its length for dissipating the shocks associated with the underlying structure. The planar strip can be C-shaped with first and second free ends coupled to the base and a mid-section coupled to the hardware component. Alternatively, the planar strip can have a C-shaped notch formed within and the bracket can include a multi-sided gusset plate that braces the base to the planar strip. The bracket is designed to improve the shock attenuation in shock sensitive designs while maintaining sufficient structural stiffness to sustain random vibration loads and minimum natural frequencies greater than 100 Hz.
