Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
103 words
An adjustable shoulder belt anchor mechanism for use in a vehicle chassis having an engaging hole comprising: an elongated adjustment base; an adjustable anchor adapted to be guided along the adjustment base; a joint connected to the adjustable anchor to support a webbing belt; a hook section at one end of the adjustment base adapted to be inserted into the engaging hole wherein either the engaging hole or the hook section has a tapering width and the engaging hole and the hook section may be moved with respect to each other in the direction of the tapering width to engage the vehicle chassis.
Claim 2
Dependent Claim
103 words
An adjustable shoulder belt anchor mechanism for use in a vehicle chassis having an engaging hole comprising: an elongated adjustment base; an adjustable anchor adapted to be guided along the adjustment base; a joint connected to the adjustable anchor to support a webbing belt; a hook section at one end of the adjustment base adapted to be inserted into the engaging hole wherein either the engaging hole or the hook section has a tapering width and the engaging hole and the hook section may be moved with respect to each other in the direction of the tapering width to engage the vehicle chassis.
Claim 3
Dependent Claim
24 words

Claim 12
Dependent Claim
32 words
The adjustable shoulder anchor mechanism of claim 1, wherein the hook section has an interlocking means to hold an edge of the vehicle chassis on a peripheral portion of the engaging hole.
Claim 13
Dependent Claim
39 words
The adjustable shoulder belt anchor mechanism of claim 11, wherein the interlocking means comprises a projection extending from the chassis of the vehicle into the engaging hole and wherein the hook section comprises an opening for engaging the projection.
Claim 14
Dependent Claim
25 words
The adjustable anchor mechanism of claim 1, wherein the hook section comprises a pair of arms and an offset raised tapered section between the arms.
Claim 15
Dependent Claim
17 words
The adjustable shoulder anchor mechanism of claim 13, wherein the engaging hole is a single rectangular opening.
Claim 16
Dependent Claim
106 words
The adjustable shoulder belt anchor mechanism of claim 1, wherein the hook section extends substantially perpendicular to the chassis and has an enlarged section provided at its end, a pair of stepped sections which extend laterally from the enlarged section, and a tapered section between the stepped sections and the adjustment base which tapers as it extends away from the adjustment base and wherein the engaging hole in the chassis has a first elongated opening into which the enlarged section of the hook section can be inserted, and a second tapering opening having its broadest edge in common with an elongated edge of the elongated opening.
Claim 17
Dependent Claim
70 words
The adjustable shoulder belt anchor mechanism of claims 1, wherein the hook section is bent toward the chassis and has a laterally enlarged section at its end substantially parallel to the adjustment base, the hook section having a pair of arms extending from the lateral ends of the enlarged section, and a tapered section extending at an angle with respect to the arms connecting the arms and the adjustment base.
Claim 18
Dependent Claim
64 words
The adjustable shoulder belt anchor mechanism of claim 1, wherein the hook section is bent toward the chassis and has an enlarged section provided at its end, the enlarged section having a pair of spaced apart stepped sections and the hook section having a reduced section substantially perpendicular to the adjustment base connecting the adjustment base and the enlarged section between the stepped sections.
Claim 19
Dependent Claim
47 words
The adjustable shoulder anchor mechanism of claim 1, wherein the engaging hole of the chassis has a first elongated opening which is wider than the widest part of the hook section, and a second contiguous tapered opening which is almost identical in width to the tapered section.
Claim 20
Dependent Claim
46 words
The adjustable shoulder belt anchor mechanism of claim 1, wherein the hook section has an opening, and a tapered projection extends from the chassis into the engaging hole for engaging the opening, the projection having a base slightly larger than the opening in the hook section.
Claim 21
Dependent Claim
58 words
The adjustable shoulder belt anchor mechanism of claim 1, wherein the hook section has an enlarged section extending parallel to but spaced apart from the adjustment base to define a pair of arms, the arms being connected to the adjustment base through a reduced section, the arms thereby defining a pair of stepped sections adjacent the reduced section.
Claim 22
Dependent Claim
36 words
The adjustable shoulder belt anchor mechanism of claim 20, wherein the hook section has an opening provided between the stepped sections, and the chassis has a projection extending into the engaging hole to engage the opening.
Claim 23
Dependent Claim
