Abstract
Abstract A vehicle safety belt includes a shoulder belt and a lap belt. A buckling tongue is adjustably attached to the end of the lap belt and includes a free rear section having a large front circular opening connected by a restricted passageway to a small rear opening. A coupling plate is attached to the end of the shoulder belt and carries a perpendicular coupling pin having a head of a diameter less than the front opening and greater than the rear opening, an intermediate cylindrical section of a diameter less than the rear opening and greater than the passageway width and a base section of a width less than the passageway width. An axially arched spring annulus engages the pin base section.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
A safety belt system comprising a lap belt, a shoulder belt, a first coupling section attached to one of said belts and having formed therein a first opening and a second opening spaced from and of lesser width than said first opening and a restricted passageway connecting said first and second openings and of lesser width than said second opening, and a second coupling section including a coupling pin having an enlarged outer head portion of greater width than said second opening and of no greater width than said first opening, an intermediate portion of no greater width than said second opening and of greater width than said passageway and an inner portion of no greater width than that of said passageway, said pin being axially movable in said second opening when said pin is in engagement therewith between a lock position with said intermediate portion engaging said second opening and in longitudinal alignment with said passageway and an unlock position with said intermediate portion out of engagement with said second opening and said inner portion in longitudinal alignment with said passageway.
Claim 2
Dependent Claim
182 words
A safety belt system comprising a lap belt, a shoulder belt, a first coupling section attached to one of said belts and having formed therein a first opening and a second opening spaced from and of lesser width than said first opening and a restricted passageway connecting said first and second openings and of lesser width than said second opening, and a second coupling section including a coupling pin having an enlarged outer head portion of greater width than said second opening and of no greater width than said first opening, an intermediate portion of no greater width than said second opening and of greater width than said passageway and an inner portion of no greater width than that of said passageway, said pin being axially movable in said second opening when said pin is in engagement therewith between a lock position with said intermediate portion engaging said second opening and in longitudinal alignment with said passageway and an unlock position with said intermediate portion out of engagement with said second opening and said inner portion in longitudinal alignment with said passageway.
Claim 3
Dependent Claim
26 words
The safety belt system of claim 1 including spring means normally urging said coupling pin to its lock position when in engagement with said second opening.
Claim 4
Dependent Claim
39 words
The safety belt system of claim 2 wherein said spring means comprises an axially arched spring annulus engaging said coupling pin and bearing on the underface of said first coupling section when said pin registers with said second opening.
Claim 5
Dependent Claim
47 words
The safety belt system of claim 1 wherein said first coupling section comprises a first plate member and said second coupling section comprises a second plate member, said coupling pin being perpendicular to said second plate and secured thereto at the base of said pin inner portion.
Claim 6
Dependent Claim
24 words
The safety belt system of claim 4 including buckle member, said first plate being integrally formed with the rear portion of said buckle member.
Claim 7
Dependent Claim
21 words
The safety belt system of claim 5 wherein said buckle member comprises a buckle coupling tongue attached to said lap belt.
Claim 8
Dependent Claim
26 words
The safety belt system of claim 1 wherein said first and second openings are circular and said pin intermediate portion is of circular transverse cross section.
Claim 9
Dependent Claim
17 words
The safety belt system of claim 7 wherein said passageway is a longitudinal slot with parallel sides.
Claim 10
Dependent Claim
18 words
The safety belt system of claim 7 wherein said pin lower portion is of circular transverse cross section.
Claim 11
Dependent Claim
18 words
The safety belt system of claim 7 wherein said pin lower portion is of elongated transverse cross section.
Claim 12
Dependent Claim
136 words
A locking device for releasably interlocking a safety shoulder belt to the buckle or tongue coupling portion of a lap belt releasable coupling comprising a connecting plate attAched to an end of said shoulder belt, a coupling pin mounted on said coupling plate and having an enlarged head and a locking section, a coupling plate section associated with said buckle or tongue coupling portion and having formed therein a pair of large and small diameter holes interconnected by a restricted cut-off, said pin locking section having a diameter between that of said small hole and the width of said cut-off, and a spring washer engaging said coupling pin, locking engagement between said connecting and coupling plate by said coupling pin being effected by the pressure of said washer on the underportion of said pin locking section.
Claim 13
Dependent Claim
136 words
A locking device for releasably interlocking a safety shoulder belt to the buckle or tongue coupling portion of a lap belt releasable coupling comprising a connecting plate attAched to an end of said shoulder belt, a coupling pin mounted on said coupling plate and having an enlarged head and a locking section, a coupling plate section associated with said buckle or tongue coupling portion and having formed therein a pair of large and small diameter holes interconnected by a restricted cut-off, said pin locking section having a diameter between that of said small hole and the width of said cut-off, and a spring washer engaging said coupling pin, locking engagement between said connecting and coupling plate by said coupling pin being effected by the pressure of said washer on the underportion of said pin locking section.
Claim 14
Dependent Claim
26 words
The device of claim 11 wherein said coupling pin includes a portion below said pin locking section of a width not exceeding that of said cut-off.
