End bracket for lateral slide rail for removable seat

A rail and carrier system for a removable seat for a motor vehicle, comprising:

• a first lower rail fixedly attached to and positioned laterally along a floor of the motor vehicle, the first lower rail having a generally U-shaped cross-sectional profile, a left lateral end, and a right lateral end;
• a first upper rail nested with and laterally slidable within the first lower rail;
• a second upper rail nested with and laterally slidable within the first lower rail;
• a second lower rail positioned laterally along the floor of the motor vehicle parallel to the first lower rail and longitudinally spaced from the first lower rail, the second lower rail having a generally U-shaped cross-sectional profile, a left lateral end, and a right lateral end;
• a third upper rail nested with and laterally slidable within the second lower rail;
• a fourth upper rail nested with and laterally slidable within the second lower rail;
• and
• four brackets, one of each of the four brackets attached at the left and right lateral ends of the first and second lower rails, each bracket comprising:
• a generally U-shaped end that is substantially similar to the U-shaped cross-sectional profiles of the first and second lower rails, the U-shaped end having a center portion and two upper portions;
• a generally L-shaped extension extending from a bottom of the center portion, the L-shaped extension having a first portion that is attached to the one of the first and second lower rails and a second portion that extends upward from the first portion;
• and
• wherein the second portion blocks movement of one of the first, second, third, and fourth upper rails.
