Abstract
A seat integrated seat belt system. A three point seat belt system includes a belt having one end affixed to the seat and an opposite end mounted to a retractor secured to the seat. A seat belt tongue is mounted to the belt intermediate the belt ends and is releasably lockable with a belt buckle on the opposite side of the seat thereby pulling one portion of the belt across the passenger lap and another portion of the belt across the passenger upper torso. The belt extends through a guide located at the top of the seat. A seat tether includes a second belt having one end attached to the seat at the location of the guide and a second end mounted to a second retractor located beneath the seat. The second retractor is operable to limit motion of the seat thereby minimizing the impact of vehicle motion on the first belt securing the passenger to the seat.
