Motion sensing seat lock

A lock for locking an aft-facing seat in an aircraft in a locked position, the lock comprising:

• a base comprising:
• a side surface having a first opening and a second opening;
• a front surface having a hub mounting portion, a first ballast retainer, and a second ballast retainer;
• a hub rotatably coupled to the hub mounting portion;
• a ballast housed within the first ballast retainer;
• four lock supports operatively coupled to the hub;
• two locking members, one locking member each being operatively coupled to two of the four lock supports;
• wherein the ballast is configured to reposition itself within the first ballast retainer from an initial position to a final position in response to a change in velocity of the aircraft;
• wherein the repositioning of the ballast from the initial position to the final position actuates the hub and causes the hub to rotate;
• wherein rotation of the hub causes the four lock supports to rotate along with the hub;
• and
• wherein rotation of the lock supports causes each of the two locking members to extend past a respective opening in the side surface and lock the aft-facing seat in the locked position.

A lock for locking an object in a vehicle in place, comprising:

• a generally cylindrical base comprising a side surface and a front surface, the side surface having a first opening and a second opening opposing said first opening, the front surface having a hub mounting portion and a ballast retaining chamber;
• a hub rotatably coupled to the hub mounting portion;
• a ballast housed within the ballast retaining chamber, the ballast being operatively coupled to the hub;
• and
• a first locking member and a second locking member each operatively coupled to the hub;
• wherein repositioning of the ballast from an initial unlocked position to a final locked position actuates the hub and causes the first locking member to extend past the first opening and the second locking member to extend past the second opening;
• wherein the ballast is configured to automatically reposition itself from the initial unlocked position to the final locked position in response to a change in velocity of the vehicle;
• wherein the front surface further comprises an alternate ballast retaining chamber opposite the ballast retaining chamber.
