A seat adjustment apparatus includes a first rail and a second rail each having a plurality of openings that extend along a longitudinal axis, the openings being defined by spaced-apart locking surfaces. A locking mechanism having first and second locking portions is configured to engage the first and second rails. The first and second locking portions are selectively rotatable between a released position and a locked position. In the locked position, the first and second locking portions are configured for relative axial movement along the longitudinal axis such that the interaction of the locking mechanism with portions of the first and second rails attenuates longitudinal freeplay therebetween.

Adjustable seat track having track engagement structure

An adjustable memory track assembly for a vehicle seat has a lower rail () adapted to be secured relative to a vehicle frame, and an upper rail () adapted to support the seat for fore/aft sliding movement relative to the lower rail (). The adjustable memory track assembly () also has a track lock assembly () operable via a first actuator () between a locked, engaged state wherein relative movement between the lower () and upper rails () is resisted, and an unlocked, disengaged state wherein the seat can be slid to and then locked in a user-selected position. The adjustable memory track assembly () is characterized in that the memory module () is provided with a blocking element to prevent rearward movement of the seat past the user-selected position independent of the locking state of the track lock assembly ().

Internal full memory module for seat tracks

A seat adjustment apparatus comprises a first rail () and a second rail () each having a plurality of openings that extend along a longitudinal axis, the openings being defined by spaced-apart locking surfaces. A locking mechanism having first () and second () locking portions is configured to engage the first and second rails. The first () and second () locking portions are selectively rotatable between a released position and a locked position. In the locked position, the first and second locking portions are configured for relative axial movement along the longitudinal axis such that the interaction of the first and second locking portions of the locking mechanism with the spaced-apart locking surfaces of the openings of the first and second rails attenuates longitudinal freeplay therebetween.

Adjustable seat track having improved track engagement structure

A vehicle seat track assembly includes a first track having first and second spaced apart walls. Each of the first and second walls include a plurality of openings formed therein. A second track is slidably mounted relative to the first track. The vehicle seat track assembly further has a locking mechanism including a first pin carried by the second track and slidably movable between an engaged position such that the first pin extends through one of the plurality of openings formed in the first wall of the first track and a disengaged position such that the first pin is retracted from the plurality of openings formed in the first wall of the first track. A second pin is carried by the second track and is slidably movable between an engaged position such that the second pin extends through one of the plurality of openings formed in the second wall of the first track and a disengaged position such that the second pin is retracted from the plurality of openings formed in the second wall of the first track. The first and second pins are movable in directions different from one another when moving into their respective engaged positions.

Positively engaged locking system for a vehicle seat

A longitudinal seat adjustment apparatus for a vehicle seat includes a first seat support member that is attachable to a vehicle. A second seat support member that is movable with respect to the first seat support member and configured to support the seat such that the seat is movable with the second seat support member is also provided. A locking member that is movable generally vertically with respect to the first and second seat support members between a locked position and an unlocked position for locking and unlocking the second seat support member with respect to the first seat support member is additionally provided. The locking member is a substantially planar two-part locking member and includes a first part generally horizontally movable with respect to a second part.
