ABSTRACT:
A seat adjuster control mechanism for an easy entry vehicle seat track having a one position memory. An overcenter cam member is rotatably mounted on a pivotal latch plate pivoted on an upper track member. The latch plate has a detent normally biased into locking engagement with a lower track member by first spring means. Upon the seat being tilted forward a pawl, which pivots about a common axis relative to the latch plate, is rotated against the bias of second spring means and engages the latch for rotation in unison therewith. This results in pawl engaging means on the cam member releasing the pawl causing the cam member pivoted from a first pawl engaging overcenter position to a second overcenter position against the bias of third spring means. In its second overcenter position the cam member maintains the locking detent clear of its locked position enabling the seat assembly to be moved to its forwardmost easy entry and exit position. Upon the seat assembly being moved rearwardly the cam member engages a camming portion on the lower track returning the cam member to its first predetermined detent locking overcenter position automatically positioning the seat assembly in a neutral or one position memory location.
