Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A plastic connecting member for connecting together two mutually-oscillating metal rocker arms, the rocker arms being components of windscreen-wiper blades, the connecting member comprising: a base portion, a pair of opposed arms extending downwards from the base portion and joined only to the base portion so as to be capable of deflection relative to the base portion, first sides of the arms being adapted to be snap-engaged into corresponding cavities on a first of said components with the connecting member held in a fixed angular position relative to said first of said components, and second, opposite sides of the arms each carrying a peg designed to be snap engaged into a respective opening of the second of said components, the pegs being formed with end-stop rims, and the base portion presenting downwards a curved ridge which rests on a top surface of the second of said components.
Claim 2
Dependent Claim
147 words
A plastic connecting member for connecting together two mutually-oscillating metal rocker arms, the rocker arms being components of windscreen-wiper blades, the connecting member comprising: a base portion, a pair of opposed arms extending downwards from the base portion and joined only to the base portion so as to be capable of deflection relative to the base portion, first sides of the arms being adapted to be snap-engaged into corresponding cavities on a first of said components with the connecting member held in a fixed angular position relative to said first of said components, and second, opposite sides of the arms each carrying a peg designed to be snap engaged into a respective opening of the second of said components, the pegs being formed with end-stop rims, and the base portion presenting downwards a curved ridge which rests on a top surface of the second of said components.
Claim 3
Dependent Claim
27 words
Connecting member according to claim 1, wherein the two mutually-oscillating components are movable relative to one another, the connecting member preventing rubbing between the two mutually-oscillating components.
Claim 4
Dependent Claim
33 words
Connecting member according to claim 1 wherein said pegs are formed on the arms on opposite sides in relation to portions snap engaged into said cavities on a first of the mutually-oscillating components.
Claim 5
Dependent Claim
28 words
Connecting member according to claim 1, wherein said arms are extensions of the base portion carried in deflecting manner on the base portion and defined between spaced openings.
Claim 6
Dependent Claim
24 words
Connecting member according to claim 1, wherein the connecting member fixes the mutually-oscillating metal rocker arms at a fixed angular position of said components.
Claim 7
Dependent Claim
29 words
Connecting member according to claim 1, wherein the two mutually oscillating metal rocker arms are each one of a center, intermediate and end rocker arm on the windscreen-wiper blades.
Claim 8
Dependent Claim
36 words
Connecting member according to claim 6, wherein the connecting member is supported in snap-engageable manner at one end of the rocker arms and supports, in snap-engageable manner, a center portion of other ones of rocker arms.
