Locking Element for a Lid to a Storage Area in a Seatback of a Vehicle

A seatback for a vehicle comprises: a lid having a closed position preventing access to a storage area and an open position allowing access to the storage area; and a locking element having an engaged position that prevents the lid from transitioning from the closed position to the open position and a disengaged position that does not prevent the lid from transitioning from the closed position to the open position; wherein, the locking element transitions from the disengaged position to the engaged position via the force of gravity when the seatback transitions from a fold down position to an upright position, and transitions from the engaged position to the disengaged position when the seatback transitions from the upright position to fold down position. The lid can pivot upward from a rearward portion of the seatback in the fold down position, as the lid transitions to the open position.
