Inertia driven rotatable upper seat portion for rear passenger head clearance

Abstract

A seating assembly for a vehicle includes a base. A seatback having a lower portion is rotatably coupled to the base and an upper portion is pivotably coupled to the lower portion by at least one pivot joint. The at least one pivot joint is disposed on a front portion of the seatback. A guide bracket is disposed on a rear portion of the seatback and is configured to guide the upper portion of the seatback between a resting position and a deployed position. A resilient member provides a resistance to pivoting of the upper portion of the seatback and the resilient member is operably coupled to the upper portion of the seatback and the lower portion of the seatback. The upper portion of the seatback pivots from the resting position to the deployed position during a frontal collision of the vehicle.
