Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A breakaway rear vision mirror assembly of the type having a mounting base and a pivoted assembly thereto to allow displacement of the mirror assembly both forwardly and rearwardly, a mirror carried by the pivoted assembly, walls defining a spring track of general `U`-shape in the pivoted assembly, a spring contained within the spring track, the spring having two ends extending from the spring track and coupled to the mounting base and an intermediate portion bearing against the spring track walls to return the pivoted assembly to a usable position after said displacement either forwardly or rearwardly, and a mirror mounting plate carrying said mirror and having a first element of a ball-and-socket joint extending from its rear surface, and said pivoted assembly comprising a cover, a second element of said ball-and-socket joint extending from said cover and engaged by said first element, said spring track extending part way around the ball.
Claim 2
Dependent Claim
152 words
A breakaway rear vision mirror assembly of the type having a mounting base and a pivoted assembly thereto to allow displacement of the mirror assembly both forwardly and rearwardly, a mirror carried by the pivoted assembly, walls defining a spring track of general `U`-shape in the pivoted assembly, a spring contained within the spring track, the spring having two ends extending from the spring track and coupled to the mounting base and an intermediate portion bearing against the spring track walls to return the pivoted assembly to a usable position after said displacement either forwardly or rearwardly, and a mirror mounting plate carrying said mirror and having a first element of a ball-and-socket joint extending from its rear surface, and said pivoted assembly comprising a cover, a second element of said ball-and-socket joint extending from said cover and engaged by said first element, said spring track extending part way around the ball.
Claim 3
Dependent Claim
31 words
A breakaway rear vision mirror assembly according to claim 1 wherein said first element of said ball-and-socket joint comprises claws which frictionally engage the said second element which comprises a ball.
Claim 4
Dependent Claim
28 words
A breakaway rear vision mirror assembly according to claim 1 comprising a spring plate, said spring track being in the spring plate and partly surrounding the ball-and-socket joint.
Claim 5
Dependent Claim
57 words
A breakaway rear vision mirror assembly according to claim 1 further comprising a spring plate, said spring track extending along each side of and partly surrounding the ball-and-socket joint, and terminating beneath portions of said spring plate, the spring plate having "lead-in" ramps which guide the spring in its movement beneath said side portions of said plate.
Claim 6
Dependent Claim
52 words
A breakaway rear vision mirror assembly according to claim 1 further comprising a tilt control lever carried by and movable in the mounting base, and a saddle extending through said tilt control lever, said spring ends engaging the saddle and urging the tilt control lever into frictional engagement with said mounting base.
Claim 7
Dependent Claim
140 words
A breakaway rear vision mirror assembly of the type having a mounting base and a pivoted assembly pivoted thereto to allow displacement of the mirror assembly both forwardly and rearwardly, a mirror carried by the pivoted assembly, walls defining a spring track of general `U`-shape in the pivoted assembly, and a spring contained within the spring track, the spring having two ends extending from the spring track and coupled to the mounting base and an intermediate portion bearing against the spring track walls to return the pivoted assembly to a usable position after said displacement either forwardly or rearwardly, and a tilt control lever carried by and movable in the mounting base, and a saddle extending through said tilt control lever, said spring ends engaging the saddle and urging the tilt control lever into frictional engagement with said mounting base.
Claim 8
Dependent Claim
140 words
A breakaway rear vision mirror assembly of the type having a mounting base and a pivoted assembly pivoted thereto to allow displacement of the mirror assembly both forwardly and rearwardly, a mirror carried by the pivoted assembly, walls defining a spring track of general `U`-shape in the pivoted assembly, and a spring contained within the spring track, the spring having two ends extending from the spring track and coupled to the mounting base and an intermediate portion bearing against the spring track walls to return the pivoted assembly to a usable position after said displacement either forwardly or rearwardly, and a tilt control lever carried by and movable in the mounting base, and a saddle extending through said tilt control lever, said spring ends engaging the saddle and urging the tilt control lever into frictional engagement with said mounting base.
