Abstract: The invention involves a two-piece seat for a passenger-carrying vehicle with the seat being capable of complying with the federal requirements with reduced complexity. A steel plate is rigidly attached to the rotating seat back. The steel plate will prevent the seat back from rotating during normal use. If the bus were in a collision, a belted occupant would apply load to the rotating seat back through the seat belts. The steel plate would deform, allowing the rotating seat back to come forward. The fixed portion of the seat back remains in position to act as a passive restraint for any passengers seated behind this particular seat. Utilizing deformable steel plates to retain and control the operation of a rotating seat back equipped with 3-point restraints is a unique aspect to this invention. The plates will retain the rotating seat back in normal use to prevent vandalism to the seat belts, and can be easily removed so the seat back can be rotated forward for servicing the seat belts and upholstery covers.

Abstract: The invention involves a seat system with a movable and immovable portions that may be maintained and still operate during transients as required under the federal regulations. There is a quick release serviceability latch for a school bus passenger seat with integrated restraints. The inner and outer seat backs must be quickly detached from one another to facilitate repair or replacement of damaged seat components. A movable plunger is rigidly attached to the inner seat back frame. Another bracket with hole to accept the plunger is rigidly attached to the back pan of the outer back. The attachment of inner to outer seat backs must be strong enough so that they can't be pulled apart by hand but at the same time be detachable in the event of a crash. A tab that engages the plunger separates upon a rapid deceleration event.

Abstract: The invention involves shifting the location of the seat belt retractor in order to reduce the thickness of the seat especially in the lower regions for a mobile vehicle seat.
