Passive seat belt system

A vehicle passive seat belt restraint system comprising:

• a seat belt adapted for restraining an occupant positioned in a seat in said vehicle, said seat belt comprising a lap portion adapted to be secured around the lap of said occupant and a shoulder portion adapted to be secured around the upper torso of said occupant;
• a lap belt retractor mounted on a door of said vehicle adjacent to said seat, one end of said lap belt portion being wound on said lap belt retractor and the opposite end of said lap belt portion being connected to a connecting means positioned at a location spaced from said door;
• a shoulder belt retractor mounted on said door, one end of said shoulder belt portion being wound on said shoulder belt retractor and the opposite end of said shoulder belt portion being connected to said connecting means whereby said lap and shoulder belt portions are connected to each other at a location spaced from said door;
• said seat belt further comprising a connecting portion having a first end connected to said vehicle at the side of said seat opposite said door and a second end connected to said connecting means;
• movable means slidably engaging said lap portion at a location intermediate its ends, said movable means permitting said seat belt to move therethrough;
• track means mounted on said door, said movable means being movable in said track means;
• means for moving said movable means from a first position at which said seat belt is in position to restrain said occupant, to a second position at which said lap portion, said shoulder portion and said connecting portion of said seat belt are in non-restraining positions;
• a second track means located in said vehicle at the side of said seat opposite said door and a second movable means movable in said second track means, said second movable means slidably engaging said connecting portion of said seat belt, said second movable means being movable from a first position adjacent the rear of said seat to a second position adjacent the front of said seat, said second movable means being in its first and second positions when said first movable means is in its first and second positions, respectively;
• a seat belt retractor connecting said first end of said connecting portion of said seat belt to said vehicle at said opposite side of said seat;
• and
• second moving means for moving said second movable means, movement of said movable means along said track means mounted on said door resulting initially in unwinding of said lap belt portion from said lap belt retractor, followed by unwinding of said connecting portion from its associated retractor, thereby permitting easy ingress to and egress from said seat.
