Abstract: A system configured to allow adjustment of a vehicle seat includes a securing bracket, an extension bracket, and a latching member. The securing bracket is configured to be secured to structure within a vehicle, and includes an adjustment guide track having a plurality of recessed grooves separated by a plurality of teeth or ribs. The extension bracket is movably secured to the securing bracket and includes a fixed arm track, a lever engaging arm positioned within the arm track, and a lever operatively connected to the lever engaging arm. The engaging arm includes a curved channel. The latching member includes a boss or knob and a protuberance. The boss is positioned within the curved channel. The protuberance is configured to be retained within each of the recessed grooves. Movement of the lever engaging arm in a first linear direction causes the latching member to move in a second linear direction that is perpendicular to the first linear direction.
