Easy entry mid-position memory seat

摘要

An automotive seat assembly (10) has a seat cushion and a seat back pivotally mounted to the seat cushion. The seat assembly includes a seat track mechanism having a lower track member (18) and an upper track member (20) supported by the lower track member (18) for movement between forward and rearward positions. An incremental locking mechanism is mounted between the upper and lower track members (18) for locking the track members in a desired position and for unlocking the track members to allow the upper track member (20) to move between the forward and rearward positions. A slide actuator is disposed adjacent the 30 locking mechanism and is moveable to an engaged position for disengaging the locking mechanism 46 and moving the upper track member (20) to a forward dump position. The seat assembly (10) also includes a positioning device which comprises a locator mounted to the upper track member (20) and moveable with the upper track member (20) as the upper track member (20) is moved to the forward dump position. The locator is interconnected to the slide actuator wherein the locator moves between a release position allowing the upper track member (20) to freely move relative to the lower track member (18) and a blocking position to align with a fixed stop which limits the movement of the upper track member (20) to a predetermined stop position upon rearward movement of the upper track member (20) from the forward dump position.
