Abstract
A vehicular seat having an adjustment apparatus for horizontally and vertically positioning the seat is provided. The adjustment apparatus includes a four bar mechanism that extends from a base and supports cushioned seat members. As the four bar mechanism is articulated with respect to the base, the seat members supported thereon are moved vertically and horizontally between elevated forward positions and lowered rearward positions. The adjustment mechanism also includes a spring for storing a portion of the energy exerted while seat members are moved from an elevated forward position to a lowered rearward position. Energy stored within the spring is used to assist lifting the seat members and the occupant therein as the seat is elevated.
