Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
46 words
A cushion member consisting essentially of a bell-shaped outer configuration such that the cross-sectional width increases along the length thereof with an axial bore with a diameter which initially decreases briefly along its length, continues uniformly, then flares to an enlarged size at the opposite end.
Claim 2
Dependent Claim
46 words
A cushion member consisting essentially of a bell-shaped outer configuration such that the cross-sectional width increases along the length thereof with an axial bore with a diameter which initially decreases briefly along its length, continues uniformly, then flares to an enlarged size at the opposite end.
Claim 3
Dependent Claim
15 words
A cushion member according to claim 1, wherein the cushion is composed of resilient material.
Claim 4
Dependent Claim
20 words
A cushion member according to claim 2, wherein deformation produces substantially complete contact between opposing surface areas of the bore.
Claim 5
Dependent Claim
54 words
A cushion member consisting essentially of an outer configuration such that it increases in cross-sectional width continuously from a point of origin along its length to a predetermined point and then decreases to its point of termination with an axial bore of initial uniform diameter which flares at a predetermined point along its length.
Claim 6
Dependent Claim
54 words
A cushion member consisting essentially of an outer configuration such that it increases in cross-sectional width continuously from a point of origin along its length to a predetermined point and then decreases to its point of termination with an axial bore of initial uniform diameter which flares at a predetermined point along its length.
