Seat track with cam actuated locking device and bypass assembly

Abstract

A vehicle seat assembly includes a seat back pivotally supported with respect to a seat bottom. The seat bottom is moveable between a generally horizontal position and a generally upright position and the seat back is moveable between a generally horizontal and upright position. The seat assembly is attached to the vehicle by a mounting assembly. The mounting assembly includes a locking device mounted on an upper track that moves relative to a lower track. The locking device moves between a locked position where the upper track cannot move with respect to the lower track and an unlocked position where the upper track can move with respect to the lower track. A release member is used to move the locking device between the locked and unlocked positions. A bypass member is supported on the second track and can be rotated independently from the release member. When an occupant wishes to disengage the locking device to slid the seat assembly forward, the bypass member and the release member rotated together to move the locking device out of the locked position. When the occupant wishes to fold the seat down to increase available cargo space, the seat bottom is pivoted into the vertical position and the seat back is pivoted into a horizontal position which causes the bypass member to rotate independently from the release member such that the locking device remains in the locked position. Additionally, after the locking device is disengaged, the bypass member can also be rotated independently from the release member allowing the locking device to be re-engaged independent of how the release member was actuated.
