  • Patent number: 7719797
    Abstract: A multi-step shock limiter in a disk drive suspension assembly has a load beam and a flexure, with a plurality of limiting pairs. A first limiting pair has a clearance less than that of any other limiting pair, and is flexible. During a shock condition, vertical movement of the flexure with respect to the load beam causes the first limiting pair to engage and absorb shock. Further movement engages at least one additional pair, redistributing the shock thereamong until all pairs engage, thereby substantially anchoring the flexure to the load beam and limiting further movement of the flexure. The limiters may comprise a double tee shape having two legs and a cross member, with the first limiter defined by the cross member between the legs, and two additional limiters defined by the ends of the cross member that extend beyond the legs. The limiters engage corresponding tabs or tongues.
