1. An occupant support comprising
a seat bottom,
a seat back including a backrest-frame support coupled to the seat bottom and arranged to extend upwardly away from the seat bottom in a normal-seating configuration, and a backrest frame coupled to the backrest-frame support and arranged to extend upward away from the backrest-frame support and the seat bottom in the normal-seating configuration, and
a seat-back mode-changing unit including a seat back recliner arranged between the seat bottom and the backrest-frame support to provide a seat-back recliner pivot axis about which the seat back pivots relative to the seat bottom between a rearward-reclined position and a forward-reclined position when the seat back is in the normal-seating configuration, and a backrest-frame brace unit coupled to the backrest-frame support and configured to block movement of the backrest frame relative to the backrest-frame support when the seat back is in the normal-seating configuration,
wherein the backrest frame is coupled to the backrest-frame support for pivotable movement relative to the backrest-frame support about a backrest-frame pivot axis that is spaced apart from the seat-back recliner pivot axis between an upright position when the backrest frame is in the normal-seating configuration and a folded-forward position in which the backrest frame folds forward toward the seat bottom relative to the backrest-frame support when the seat back pivots forward past the forward-reclined position,
wherein the backrest-frame brace unit includes a backrest-frame pivot-blocker lever coupled to the backrest-frame support, a slip-blocker lever coupled to the backrest-frame support, and a fixed stop coupled to at least one of the seat bottom and the seat-back recliner, and wherein the slip-blocker lever is configured to engage the fixed stop to change the backrest-frame pivot-blocker lever from an engaged position to a freed position in which the backrest frame is free to pivot about the backrest-frame pivot axis,
wherein the fixed stop is stationary and remains fixed relative to the slip-blocker lever in response to the seat back pivoting between the forward-reclined position.
