Abstract
Abstract The disclosure relates to a seat belt control system for a two-door vehicle having a folding front seat. As the front seat is folded forward, an arm mounted along the side of the back of the seat raises the shoulder strap out of the entrant's way, thus providing unobstructed access to the rear seat of the vehicle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
In a vehicle having a seat provided with a back which is foldable forwardly, a door port permitting access to said seat and to the area in rear thereof when said back is folded forwardly, a shoulder strap extending normally from a point behind said foldable back near the top of said vehicle downwardly to the upper corner of said back adjacent to said door port, a guide member having an aperture at the top through which the shoulder strap extends, said guide member having a downwardly extending rod, a tube on said foldable back in which the rod extends, a pair of interconnected pulleys of different diameter mounted near the base of said back, flexible means connecting the pulley of smaller diameter adjacent to the seat, flexible means connecting the pulley of large diameter to said rod whereby when the back is folded forwardly the rotation of the two pulleys due to the one flexible means wound on the pulley of smaller diameter operates the flexible member on the pulley of larger diameter to extend the rod and therefor the guide member a greater distance than would have occurred if the pulleys were of the same diameter.
Claim 2
Dependent Claim
198 words
In a vehicle having a seat provided with a back which is foldable forwardly, a door port permitting access to said seat and to the area in rear thereof when said back is folded forwardly, a shoulder strap extending normally from a point behind said foldable back near the top of said vehicle downwardly to the upper corner of said back adjacent to said door port, a guide member having an aperture at the top through which the shoulder strap extends, said guide member having a downwardly extending rod, a tube on said foldable back in which the rod extends, a pair of interconnected pulleys of different diameter mounted near the base of said back, flexible means connecting the pulley of smaller diameter adjacent to the seat, flexible means connecting the pulley of large diameter to said rod whereby when the back is folded forwardly the rotation of the two pulleys due to the one flexible means wound on the pulley of smaller diameter operates the flexible member on the pulley of larger diameter to extend the rod and therefor the guide member a greater distance than would have occurred if the pulleys were of the same diameter.
Claim 3
Dependent Claim
19 words
A seat belt control system for a vehicle as recited in claim 1, wherein said flexible means are cables.
Claim 4
Dependent Claim
46 words
A seat belt control system for a vehicle as recited in claim 1, wherein spring means are tensioned when the rod is extended by said flexible means for returning the rod and pulleys to their original position when the back is returned to its normal position.
Claim 5
Dependent Claim
66 words
A seat belt control system for a vehicle as recited in claim 1, wherein said pulleys of different diameters are mounted secured against relative rotation on a single shaft which is supported at the base of the foldable back, the pulley of smaller diameter being coupled to the input of the mechanism and the pulley of larger diameter being coupled to the output of said mechanism.
