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. The seat may be used for a mobile vehicle as a school bus as well as for automotive applications. The seat belt retractors are attached to a portion of the seat structure that allows the webbing to exit the retractor on the front surface of the seat back. The webbing is then allowed to cross over to the rear surface of the seat back as it rises to the turning-loop. The retractor may be located forward of the seat back pivot point on the seat frame in order to allow for the webbing to exit on the front surface of the seat back.

We claim: 1. A passenger seat for a multi-passenger motor vehicle, the vehicle having a body with a seat mounting surface, comprising: a seat frame, mountable to the seat mounting surface; an immovable rear seat frame engaged to said seat frame, said rear seat frame providing an energy absorbing obstruction to protect a passenger of a vehicle rearward seat from moving out of his safety zone in a forward direction in the event of a vehicle rapid deceleration; a movable front frame, pivotably engaged to said seat frame forward of said immovable rear seat frame, said movable front frame providing a back resting surface for a passenger; said immovable rear frame being comprised of a rear frame seat structure, and an energy absorbing back pan with foam padding; a three point seat belt engaged to a seat belt retractor, said retractor being engaged to said seat frame, said seat belt causing a pivoting force upon said movable front frame during an activation event; said seat belt retractor being attached to a portion of said seat frame allowing webbing of said seat belt to exit said retractor onto a front surface of said movable front frame; said seat belt webbing crossing over to a rear surface of said front frame through a front frame web slot passing through said front frame; said seat belt running over a turning-loop engaged to said movable front frame; and said energy absorbing back pan having four sides, with three of said sides engaged to said rear frame seat structure, with a fourth lower horizontal side not attached to said rear frame seat structure. 2. The passenger seat for a multi-passenger motor vehicle of claim 1, wherein: said back pan having foam on a rearward side, said foam including an upper foam zone and a lower knee impact zone, said knee impact zone having a foam thickness less than said upper foam zone foam thickness. 3. The passenger seat for a multi-passenger motor vehicle of claim 2, wherein: said knee impact zone thickness being less than or equal to one third of said upper zone thickness. 4. A passenger seat for a multi-passenger motor vehicle, the vehicle having a body with a seat mounting surface, comprising: a seat frame, mountable to the seat mounting surface; an immovable rear seat frame engaged to said seat frame, said rear seat frame providing an energy absorbing obstruction to protect a passenger of a vehicle rearward seat from moving out his safety zone in a forward direction in the event of a vehicle rapid deceleration; a movable front frame, pivotably engaged to said seat frame forward of said immovable rear seat frame, said movable front frame providing a back resting surface for a passenger; said immovable rear frame being comprised of a rear frame seat structure, and an energy absorbing back pan with foam padding; a three point seat belt engaged to a seat belt retractor, said retractor being engaged to said seat frame, said seat belt causing a pivoting force upon said movable front frame during an activation event; said seat belt retractor being attached to a portion of said seat frame forward of a pivot point of said movable front frame allowing webbing of said seat belt to exit said retractor onto a front surface of said movable front frame; said seat belt webbing crossing over to a rear surface of said front frame through a front frame web slot passing through said front frame; said seat belt running over a turning-loop engaged to said movable front frame; said energy absorbing back pan having four sides, with three of said sides engaged to said rear frame seat structure, with a fourth lower horizontal side not attached to said rear frame seat structure; and said back pan having foam on a rearward side, said foam including an upper foam zone and a lower knee impact zone, said knee impact zone having a foam thickness less than said upper foam zone foam thickness. 5. The passenger seat for a multi-passenger motor vehicle of claim 4, wherein: said knee impact zone thickness being less than or equal to one third of said upper zone thickness. 6. A multi-passenger motor vehicle, comprising: a body with a seat mounting surface; at least two passenger seats, one said passenger seat having seat frame, mounted to said seat mounting surface; an immovable rear seat frame engaged to said seat frame, said rear seat frame providing an energy absorbing obstruction to protect a passenger of a vehicle rearward seat from moving out his safety zone in a forward direction in the event of a vehicle rapid deceleration; a movable front frame, pivotably engaged to said seat frame forward of said immovable rear seat frame, said movable front frame providing a back resting surface for a passenger; said immovable rear frame being comprised of a rear frame seat structure, and an energy absorbing back pan with foam padding as said energy absorbing obstruction; a three point seat belt engaged to a seat belt retractor, said retractor being engaged to said seat frame, said seat belt causing a pivoting force upon said movable front frame during an activation event; said seat belt retractor being attached to a portion of said seat frame forward of a pivot point of said movable front frame allowing webbing of said seat belt to exit said retractor onto a front surface of said movable front frame; said seat belt webbing crossing over to a rear surface of said front frame through a front frame web slot passing through said front frame; said seat belt running over a turning-loop engaged to said movable front frame; and said energy absorbing back pan having four sides, with three of said sides engaged to said rear frame seat structure, with a fourth lower horizontal side not attached to said rear frame seat structure. 7. The multi-passenger motor vehicle of claim 6, wherein: said back pan having foam on a rearward side, said foam including an upper foam zone and a lower knee impact zone, said knee impact zone having a foam thickness less than said upper foam zone foam thickness. 8. The multi-passenger motor vehicle of claim 7, wherein: said knee impact zone thickness being less than or equal to one third of said upper zone thickness.
