Abstract: A seat base for use in aircraft has a first cross member, a second cross member, a first leg, a second leg, and a base plate having a first bendable tab and a second bendable tab facing away from the first tab. The first cross member, the second cross member, and the base plate are each configured to be secured to the first and second legs in an extended position and a retracted position. The first and second legs are configured to be secured to seat feet and floor tracking rails. The first and second cross members are secured to the base plate so as to allow for selective rotation of the first and second cross members in response to relative vertical movement of the first leg with respect to the second leg.

Abstract: A lock for locking an object in a vehicle in place comprises a base comprising a side surface and a front surface. The side surface has at least one opening, and the front surface has a ballast retainer and a hub mounting portion. A hub is rotatably coupled to the hub mounting portion. A ballast, which is operatively coupled to the hub, is housed within the ballast retainer. At least one locking member is also operatively coupled to the hub. The ballast is configured to automatically reposition itself within the ballast retainer from an initial unlocked position to a final locked position in response to a change in velocity of the vehicle. This repositioning of the ballast actuates the hub, and causes the at least one locking member to extend past the at least one opening.
