Abstract
Abstract A vehicle seat including a seat cushion and a seat back is conventionally mounted on the vehicle floor by a track assembly which permits fore and aft adjustment of the seat. The seat back includes inboard and outboard support arms which are respectively mounted to the frame of the seat cushion by pivots to permit forward tilting movement of a seat back to an easy-enter position. A first link is pivotally mounted on one of the pivots of the seat back and has its other end pivoted to a second link which is in turn pivoted to a stationary member. A latch acting between the seat back and the first link can be unlatched to permit fore and aft adjusting movement of the vehicle seat and consequent rotation of the first link about the pivot while the seat back remains in its normal position. When the seat back is tilted forwardly, the latch causes the first link to be rotated with the seat back causing the entire vehicle seat to be pulled forwardly on the track assembly by virtue of the connection of the other end of the first link to the stationary member by the second link.
