ABSTRACT:
A vehicle recliner seat is provided which, in a preferred embodiment, includes a seat bun frame, a seat back frame pivotally mounted with respect to the seat bun frame, an adjuster to selectively adjust the inclination of the seat back frame with respect to the seat bun frame, a strut pivotally mounted to the seat back along a first fixed pivotal axis and having a lost motion pivotal attachment with the seat bun frame, the strut having on an end adjacent to the seat bun frame a pin which is provided for translational movement with respect to the seat bun frame, and the seat bun frame having a pivotal latch and a pendulum to actuate the latch wherein, when the vehicle accelerates rearwardly over a predetermined level of rearward acceleration, the pendulum causes the latch to pivot upwardly to engage the pin, causing the strut to have a fixed pivotal axis with the seat bun frame and thereby tend to limit rearward motion of the seat back frame.
