1. A vehicle seat comprising:
- a seatback having a pivot rotationally coupled to a base that is slidable along a track between a plurality of comfort positions;
a track-overslide actuator in communication with the pivot and the track, wherein operation of the pivot to a rear-entry position activates the track-overslide actuator to provide slidable forward operation of the base along the track beyond the plurality of comfort positions wherein the track-overslide actuator includes an overslide cam that directly engages an overslide surface of the pivot; and
an interlock actuator in communication with the pivot and the track, wherein when the track-overslide actuator is activated, forward operation of the base along the track activates the interlock actuator into a blocking position to lock the pivot in the rear-entry position, wherein rearward sliding movement of the base back to the plurality of comfort positions disengages the interlock actuator from the blocking position and movement of the pivot to an upright position disengages the track-overslide actuator, wherein the interlock actuator includes an interlock cam that directly engages an interlock surface of the pivot, wherein a first spring extends between the overslide and interlock cams to bias the interlock cam toward the blocking position, and wherein a second spring biases the interlock cam away from the blocking position.

Abstract
A vehicle seat includes a seatback pivot rotationally operable relative to a slidable base, a first cam in communication with the seatback pivot to activate a track-overslide actuator of the base when the seatback pivot is in a rear-entry position and a second cam in communication with the seatback pivot. When the track-overslide actuator is activated, forward operation of the base locks the seatback pivot in the rear-entry position.

6. A vehicle seat comprising:
-
a pivot rotationally operable relative to a slidable base; an overslide cam in communication with the pivot to bias an interlock cam toward the pivot when the pivot is in a rear-entry position; a track-overslide actuator that cooperates with the overslide cam to engage the interlock cam with the pivot and lock the pivot in the rear-entry position upon forward operation of the slidable base; a first spring that extends between the overslide cam and the interlock cam to bias the interlock cam into engagement with the pivot; and a second spring coupled with the interlock cam that biases the interlock cam to an offset position that is distal from the pivot. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A vehicle seat comprising:
-
a seatback having a pivot in communication with a seat-base slide; a first spring extending between an interlock cam and an overslide cam that exerts a first biasing force against the interlock cam toward engagement with the pivot; a second spring that exerts a second biasing force to bias the interlock cam away from the pivot and toward an offset position;
wherein;the second biasing force is greater than the first biasing force when the seatback is in an upright position indicative of a deactivated state of the overslide cam; the first biasing force is greater than the second biasing force when the seatback is rotated to a rear-entry position; and the second biasing force is greater than the first biasing force when the seatback in the rear-entry position is disposed in an overslide position in relation to the seat-base slide. - View Dependent Claims (16, 17, 18, 19)
