Abstract:
1. A seat adjustment apparatus comprising: a first rail having a plurality of openings that extend along a longitudinal axis, the openings being defined by spaced-apart locking surfaces; a second rail having a plurality of complementary openings extending along the longitudinal axis, the complementary openings being defined by spaced-apart locking surfaces; and a locking mechanism having first and second locking portions, the first and second locking portions being selectively rotatable between a released position, where the first and second rails can move freely relative to one another along the longitudinal axis, and a locked position, where each of the first and second locking portions include a plurality of teeth extending into selected ones of the openings and complementary openings in the first and second rails to maintain the first rail in a selected position relative to the second rail, the first and second locking portions being further configured for relative axial movement along the longitudinal axis as the locking mechanism is moved from the released position to the locked position such that at least one of the teeth of each of the first and second locking portions are engageable with a respective locking surface to attenuate longitudinal freeplay between the first and second rails.
