An inertia locking mechanism for a bin having a bin lid and subjectable to an applied force resulting in an acceleration includes a housing attachable to the bin, a bracket attachable to the bin lid and having a locking feature, a locking pin, a biasing member, and a trigger. The locking pin is linearly moveable in the housing. The trigger has a triggering mass and is connected to the housing via a trigger pivot. The triggering mass is offset from the trigger pivot such that the triggering mass applies a torque to the trigger when the acceleration occurs in each of the front, rear, left, and right directions. The trigger is configured to release the locking pin when the acceleration exceeds a threshold acceleration such that the biasing member urges the locking pin into the locking feature of the bracket to lock the bin lid in a closed position.
