Abstract
The invention provides a seat for a bus that has a movable front frame or seat back that a seat occupant rests his or her back against normally. The front frame is the mounting point for the upper portion of a three-point seat belt. The seat frame contains a rear passenger support wall or rear frame to protect a passenger of rearward seat from moving out his safety zone in a forward direction in the event of a rapid deceleration. The rear frame is part of the seat frame and only moves upon initial contact by a rearward-unbelted passenger impact. A rotation guide slot defines the amount of rear frame movement. The front frame is limited in the amount of its forward pivoting movement by a tether, spring or fluid dampener that is engaged to an immovable portion of the frame and thereby limits forward travel of the front frame.
