1. An occupant support comprising:
a seat bottom,
a seat back coupled to the seat bottom and arranged to extend upwardly away from the seat bottom, the seat back including a headrest and a backrest located between the headrest and the seat bottom, and
a reactive-occupant positioner coupled to the seat back to move therewith and configured to arrange an occupant on the occupant support in response to an impact event so that the occupant moves from:
a pre-event arrangement in which a torso of the occupant is arranged a first distance from a frame of the seat back,
to an event arrangement in which the torso of the occupant is arranged a second distance from the frame that is less than the first distance, and
to a post-event arrangement in which the torso of the occupant is arranged a third distance from the frame that is greater than the second distance after the impact event is complete without repair of the reactive-occupant positioner,
wherein, in response to the impact event, the reactive-occupant positioner changes from a pre-event configuration in which the reactive-occupant positioner causes the occupant to be in the pre-event arrangement, to an event configuration in which the reactive-occupant positioner causes the occupant to be in the event arrangement,
wherein the reactive-occupant positioner includes a rear platform coupled to the seat back to move therewith and a front platform movable relative to the rear platform,
wherein, in the pre-event configuration, the reactive-occupant positioner has a first thickness defined between the front platform and the rear platform, in the event configuration, the reactive-occupant positioner has a second thickness defined between the front platform and the rear platform that is less than the first thickness, and, in the post-event configuration, the reactive-occupant positioner has a third thickness defined between the front platform and the rear platform that is greater than the second thickness,
wherein the reactive-occupant positioner further includes a bias unit coupled to the front platform and to the rear platform and configured to bias the front platform away from the rear platform toward the pre-event configuration of the reactive-occupant positioner prior to application of the impact force and toward the post-impact configuration of the reactive-occupant positioner after application of the impact force to the occupant support, and
wherein the reactive-occupant positioner further includes a first arm linkage and a second arm linkage, the first arm linkage pivotably coupled to a first top edge of the front platform and a second top edge of the rear platform, and the second arm linkage pivotably coupled to a first bottom edge of the front platform and a second bottom edge of the rear platform.
