Seat track easy-entry actuation mechanism

摘要

A seat track assembly includes a seat track operable for sliding movement of a seat assembly. A towel bar pivots a drive lever unlocking the seat track and allowing sliding movement of the seat assembly within a range of comfort positions. A stop lever pivots between a lowered position and a raised position. In the lowered position, the stop lever engages a stop bracket secured to the seat track preventing the seat assembly from moving forward of the range of comfort positions. A cam pivots in response to pivotally moving a seat back to a dump position. Pivoting the cam pivots the drive lever unlocking the seat track and pivots the stop lever to the raised position spaced above the stop bracket to allow sliding movement of the seat assembly to an easy-entry position forward of the range of comfort positions.
