Seat track assembly with vertical dislocation resistance bracket

A seat track assembly comprising, in combination:

• a lower track assembly comprising first and second lower tracks laterally spaced from and aligned generally parallel with one another,
• an upper track assembly operably engaging the lower track assembly and comprising a first upper track and a second upper track carried over the first and second lower track, respectively, each of the upper tracks forming in cooperation with each of the corresponding lower tracks an elongate central channel;
• a first upper bracket and a second upper bracket rigidly attached to the first and second upper track, respectively, each of the upper brackets having first and second projections positioned externally of the corresponding central channels and extending toward each corresponding central channels;
• and
• a first elongate lower bracket and a second elongate lower bracket rigidly attached to the first and second lower track, respectively, each of the lower brackets having elongate left and right flanges, such that in a normal operating condition the external upper bracket projections slide free of the lower bracket flanges, and the first and second external projections of each of the upper brackets are received by the left and right flanges of each of the lower brackets, respectively, to resist vertical dislocation of the corresponding upper track.

A seat track assembly comprising, in combination:

• a lower track assembly comprising first and second lower tracks laterally spaced from and aligned generally parallel with one another;
• an upper track assembly operably engaging the lower track assembly and comprising a first elongate upper track and a second elongate upper track slidably mounted on the first and second lower track, respectively;
• each of the upper tracks comprising longitudinally extending left and right flanges, and each of the lower tracks comprising longitudinally extending left and right flanges, wherein the left and right flanges of each of the upper tracks receive a corresponding downward portion of the left and right flanges, respectively, of the corresponding lower track to resist vertical dislocation of each of the upper tracks from each of the lower tracks;
• a first upper bracket and a second upper bracket rigidly attached to the first and second upper track, respectively, each of the upper brackets having first and second projections positioned externally of and on opposite sides of the corresponding upper track;
• and
• a first elongate lower bracket and a second elongate lower bracket rigidly attached to the first and second lower track, respectively, each of the lower brackets having elongate left and right flanges, in a normal operating condition the external upper bracket projections slide free of the lower bracket flanges, and the first and second external projections of each of the upper brackets are received by the left and right flanges of each of the lower brackets, respectively, to resist vertical dislocation of the corresponding upper track.
