Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
190 words
A ball-joint assembly including a bearing member for connecting a ball-stud member to a link and providing relative pivotal movement therebetween, said ball-stud member including a ball portion integrally connected to a neck portion, said link comprising a base plate portion which is formed with a plurality of tabs bent over for maintaining said bearing member in engagement with said base plate portion, said bearing member comprising a first socket portion formed with a first spherical bearing surface, a second socket portion formed with a second spherical bearing surface and having a cut-out portion for receiving said neck portion of said ball-stud member during assembly of said ball-stud member and said bearing member; a flexible web connecting said first and second socket portions and serving as a hinge for permitting said first and second socket portions to be coaxially aligned with said ball portion of said ball-stud member located between said first and second spherical bearing surfaces; and means formed with said base plate portion and cooperating with said flexible web for limiting relative movement between said bearing member and said link about the longitudinal axis of said ball-stud member.
Claim 2
Dependent Claim
190 words
A ball-joint assembly including a bearing member for connecting a ball-stud member to a link and providing relative pivotal movement therebetween, said ball-stud member including a ball portion integrally connected to a neck portion, said link comprising a base plate portion which is formed with a plurality of tabs bent over for maintaining said bearing member in engagement with said base plate portion, said bearing member comprising a first socket portion formed with a first spherical bearing surface, a second socket portion formed with a second spherical bearing surface and having a cut-out portion for receiving said neck portion of said ball-stud member during assembly of said ball-stud member and said bearing member; a flexible web connecting said first and second socket portions and serving as a hinge for permitting said first and second socket portions to be coaxially aligned with said ball portion of said ball-stud member located between said first and second spherical bearing surfaces; and means formed with said base plate portion and cooperating with said flexible web for limiting relative movement between said bearing member and said link about the longitudinal axis of said ball-stud member.
Claim 3
Dependent Claim
