Abstract
Abstract A dust seal for ball joint assembles of a type commonly used in motor vehicle steering linkages having external and internal ribs and primary and secondary sealing lips to prevent the dust seal from becoming damaged by entrapment between the ball stud member and the body of a joint assembly and to improve the sealing properties of effectiveness of the structure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
107 words
A device for sealing the stud end of a ball joint assembly having a ball stud member and a body member which comprises, a substantially hoLlow hemispherical sealing member of a flexible resilient material having a large opening substantially at an equatorial position on the hemispherical member to engage a side surface of the body member, a smaller stud opening at a polar location relative to the equatorial opening to engage with a surface of the ball stud member, and a generally annular axially depending internal integral skirt to bear on an end surface of the body member adjacent to said side surface of the body member.
Claim 2
Independent Claim
107 words
A device for sealing the stud end of a ball joint assembly having a ball stud member and a body member which comprises, a substantially hoLlow hemispherical sealing member of a flexible resilient material having a large opening substantially at an equatorial position on the hemispherical member to engage a side surface of the body member, a smaller stud opening at a polar location relative to the equatorial opening to engage with a surface of the ball stud member, and a generally annular axially depending internal integral skirt to bear on an end surface of the body member adjacent to said side surface of the body member.
Claim 3
Dependent Claim
46 words
A device for sealing the stud end of a ball joint assembly as defined in claim 1 which also comprises a plurality of solid-spaced integral external ribs extending radially outward from and longitudinally on at least a portion of the exterior surface of the hemispherical member.
Claim 4
Dependent Claim
32 words
A device for sealing the stud end of a ball joint assembly as defined in claim 2 in which said external ribs extend substantially from the stud opening to the equatorial opening.
Claim 5
Dependent Claim
46 words
A device for sealing the stud end of a ball joint assembly as defined in claim 2 which also comprises a plurality of solid-spaced integral internal ribs extending radially inward from and longitudinally on at least a portion of the interior surface of the hemispherical member.
Claim 6
Dependent Claim
47 words
A device for sealing the stud end of a ball joint assembly as defined in claim 4 in which said external ribs extend substantially from said polar opening to said equatorial opening and in which said internal ribs extend substantially from said polar opening to said skirt.
Claim 7
Dependent Claim
35 words
A device for sealing the stud end of a ball joint assembly as defined in claim 5 in which said internal ribs are circumferentially spaced such that they are interposed between said spaced external ribs.
Claim 8
Dependent Claim
46 words
A device for sealing the stud end of a ball joint assembly as defined in claim 1 which also comprises a plurality of solid-spaced integral internal ribs extending radially inward from and longitudinally on at least a portion of the interior surface of the hemispherical member.
Claim 9
Dependent Claim
31 words
A device for sealing the stud end of a ball joint assembly as defined in claim 7 in which said internal ribs extend substantially from the polar opening to said skirt.
Claim 10
Independent Claim
120 words
A device for sealing the stud end of a ball joint assembly having a ball stud member and a body member which comprises, a substantially hollow hemispherical sealing member of a flexible resilient material having a large opening substantially at an equatorial position on the hemispherical member to engage a side surface of the body member, a smaller stud opening at a polar location relative to the equatorial opening to engage a surface of the ball stud member, plurality of solid-spaced integral external ribs extending radially outward from and longitudinally on the exterior surface of said hemispherical member, and a plurality of solid-spaced integral internal ribs extending radially inward from and longitudinally on the interior surface of said hemispherical member.
Claim 11
Independent Claim
120 words
A device for sealing the stud end of a ball joint assembly having a ball stud member and a body member which comprises, a substantially hollow hemispherical sealing member of a flexible resilient material having a large opening substantially at an equatorial position on the hemispherical member to engage a side surface of the body member, a smaller stud opening at a polar location relative to the equatorial opening to engage a surface of the ball stud member, plurality of solid-spaced integral external ribs extending radially outward from and longitudinally on the exterior surface of said hemispherical member, and a plurality of solid-spaced integral internal ribs extending radially inward from and longitudinally on the interior surface of said hemispherical member.
Claim 12
Dependent Claim
55 words
A device for sealing the stud end of a ball joint assembly as defined in claim 9 in which said external ribs extend longitudinally substantially from said polar opening to said equatorial opening and in which said internal ribs extend longitudinally substantially from said polar opening to approximately halfway between said polar and equatorial opening.
Claim 13
Dependent Claim
34 words
A device for sealing the stud end of a ball joint assembly as defined in claim 10 in which said internal ribs are circumferentially spaced so that they are interposed between said external ribs.
Claim 14
Dependent Claim
34 words
A device for sealing the stud end of a ball joint assembly as defined in claim 9 in which said internal ribs are circumferentially spaced so that they are interposed between said external ribs.
