Abstract
Abstract An integrally formed low friction anchor ring guide having a flat anchor tab upper end portion with an anchor bolt opening therethrough, a transversely bent central portion having a seat belt webbing slot with curved end portions, and a lower rolled end portion aligned with the webbing slot so that tangential entrainment of seat belt webbing occurs over the rolled portion as the webbing passes through the webbing slot. A tension stop lock-out block may be pivotally secured to the rolled end portion of the ring guide. The tension stop block includes a central jaw portion provided with gripping teeth adapted to lockably engage the webbing upon selective rotation of the lock-out block.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A low friction guide loop comprising: an integrally formed anchor plate ring guide member having a flat anchor tab upper end portion, a transversely bent central portion provided with an elongate webbing slot therethrough, and a lower rolled end portion in spaced-apart alignment with said webbing slot so that seat belt webbing passing through said slot is entrained over said rolled end portion, said lower rolled end portion rolled upwardly toward said upper end portion, said lower rolled end portion terminating proximate to and in spaced-apart register with said elongate webbing slot.
Claim 2
Dependent Claim
92 words
A low friction guide loop comprising: an integrally formed anchor plate ring guide member having a flat anchor tab upper end portion, a transversely bent central portion provided with an elongate webbing slot therethrough, and a lower rolled end portion in spaced-apart alignment with said webbing slot so that seat belt webbing passing through said slot is entrained over said rolled end portion, said lower rolled end portion rolled upwardly toward said upper end portion, said lower rolled end portion terminating proximate to and in spaced-apart register with said elongate webbing slot.
Claim 3
Dependent Claim
29 words
The anchor ring guide member of claim 1 wherein an anchor bolt hole is provided through the anchor tab upper end portion and said anchor tab is triangularly configured.
Claim 4
Dependent Claim
20 words
The anchor ring guide member of claim 1 wherein the webbing slot is provided with upwardly curved arcuate end portions.
Claim 5
Dependent Claim
131 words
A low friction guide loop assembly and tension lock-out comprising: a. an integrally formed anchor ring guide member having a flat anchor tab upper end portion, a transversely bent central portion provided with an elongate webbing slot therethrough and a lower rolled end portion in spaced-apart alignment with said webbing slot so that seat belt webbing passing through said slot is entrained over said rolled end portion; and b. a tension block lock member pivotally mounted on said lower rolled end portion, said tension block lock member provided with a central gripping jaw portion adapted to make locking engagement with seat belt webbing entrained over said rolled end portion when selectively rotated about the axis formed by said rolled end portion toward said anchor ring guide and clamping on said webbing.
Claim 6
Dependent Claim
131 words
A low friction guide loop assembly and tension lock-out comprising: a. an integrally formed anchor ring guide member having a flat anchor tab upper end portion, a transversely bent central portion provided with an elongate webbing slot therethrough and a lower rolled end portion in spaced-apart alignment with said webbing slot so that seat belt webbing passing through said slot is entrained over said rolled end portion; and b. a tension block lock member pivotally mounted on said lower rolled end portion, said tension block lock member provided with a central gripping jaw portion adapted to make locking engagement with seat belt webbing entrained over said rolled end portion when selectively rotated about the axis formed by said rolled end portion toward said anchor ring guide and clamping on said webbing.
Claim 7
Dependent Claim
35 words
The low friction guide loop assembly of claim 4 wherein the bottom surface of said gripping jaw portion is provided with gripping teeth which lockably engage seat belt webbing entrained over said rolled end portion.
