Abstract
A seat assembly includes an easy-entry system with a seat frame having a seatback pivotally coupled to a seat member. An external lever is operably coupled to an engagement lever disposed on the seat frame and is configured to activate the engagement lever to move the seatback into an engaged position with a sector pivotally coupled to the seat frame. A disengagement rod flexibly is coupled to a spring member disposed on the sector at a first end and further coupled to a track release lever at a second end. As such, rotation of the seatback to a release position rotates the track release lever to unlock the seat assembly from a seat track. Further rotation of the seatback from the release position to an over-travel position loads the spring member but does not further rotate the track release lever.
Claims19
A seat assembly, comprising:
- a seatback pivotally coupled to a seat member between use, release and over-travel positions;
- a sector and a track release lever pivotally coupled to the seat member for rotation with the seatback;
- and
- a disengagement rod coupled to a spring member mounted on a body portion of the sector and further coupled to the track release lever, wherein rotation of the seatback to the release and over-travel positions causes the track release lever to unlock the seat assembly from a seat track.
A seat assembly, comprising:
- a seatback pivotally coupled to a seat member;
- a sector and a track release lever pivotally coupled to the seat member for rotation with the seatback;
- a biasing member mounted on the sector;
- and
- a disengagement rod having first and second ends, wherein the first end is coupled to the biasing member and further wherein the second end is coupled to the track release lever;
- wherein rotation of the seatback to one of a release position and over-travel position causes the track release lever to unlock the seat assembly from a seat track.
A seat assembly, comprising:
- a seat frame including a pivoting seatback and a seat member;
- a disengagement rod and spring member coupled between a sector and a track release lever, wherein pivoting the seatback to a release position rotates the sector and the track release lever to unlock the seat assembly from a seat track;
- and
- wherein the seatback is moveable to an over-travel position wherein the spring member loads as the sector rotates.
