Two stage crush zone latch

A latch comprising:

• a housing;
• a ratchet pivotably mounted to said housing by a rivet for rotation about a first axis between a latched and unlatched configuration;
• said ratchet having a slot extending therethrough with an arcuate portion generally concentric with said first axis and a first radial portion extending generally radially from said first axis;
• a pawl assembly having a roller extending through said slot and mounted to said housing for movement relative to said ratchet between said first arcuate portion and said first radial portion, said roller having a roller axis, said pawl assembly operatively coupled between said housing and said ratchet for moving said roller from said arcuate portion of said slot with said ratchet in said unlatched configuration to said first radial portion of said slot with said ratchet in said latched configuration;
• and
• a flange extending from said housing across said ratchet to limit pivotal movement of said ratchet about said roller axis;
• whereby
• said rivet is deformable to force said ratchet to rotate about said roller axis when said roller is seated in said first radial portion and said ratchet is in said latched configuration upon said ratchet being exposed to an unlatching force above a predetermined threshold value.
