Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
180 words
A chair comprisinG: the stacked assembly of a stationary base plate, a rotatably mounted mirror support plate, a rotatably mounted seat, and a stationary bearing support means supporting a plurality of rolling members disposed between said mirror support plate and said seat for causing rotation imparted to said seat to be transmitted by said rolling members to said mirror support plate to effect counterrotation thereof; a support arm secured with one end to said mirror support plate for motion therewith, said arm radially extending from said mirror support plate rearwardly of said seat and supporting at its distal end a bracket adapted to undergo pivotal motion relative to said support arm; means extending from said bracket for supporting a mirror above the height of said seat and in a generally vertically disposed plane; cam means disposed on said base plate, and linkage means coupling said cam means to said bracket for pivoting said bracket and the face of the mirror supported by said bracket from a central position responsive to the rotation of said seat and said mirror support plate.
Claim 2

A chair as set forth in claim 1, said cam means being a curved track and said linkage means comprising a rod coupled with one end to said track and with the other end to said bracket.
Claim 5
Dependent Claim
20 words
A chair as set forth in claim 3, said rod being supported by said mirror support plate for rotation therewith.
Claim 6
Dependent Claim
29 words

Claim 7
Dependent Claim
29 words
A chair as set forth in claim 5, said means extending from said bracket providing the mirror to be adjusted in its height above the level of said seat.
Claim 8
Dependent Claim
14 words
A chair as set forth in claim 1, said rolling members comprising spherical elements.
Claim 9
Dependent Claim
42 words
A chair as set forth in claim 1, said mirror support plate, said seat and said bearing support means being secured by a non-rotating central bolt to said base plate, and means disposed for securing said bearing support means to said bolt.
Claim 10
Dependent Claim
22 words
A chair as set forth in claim 1, said base having legs extending therefrom for elevating said assembly from a support surface.
Claim 11
Dependent Claim
22 words
A chair as set forth in claim 1, and stop means disposed for limiting the rotational excursion of said mirror support plate.
Claim 12
Dependent Claim
175 words
A chair comprising: the stacked assembly of a stationary base plate, a rotatably mounted mirror support plate, a rotatably mounted seat, and bearing means disposed between said mirror support plate and said seat for causing rotation of said seat to be transmitted by said bearing means to said mirror support plate for effecting counterrotation thereof; a support arm secured with one end to said mirror support plate for motion therewith, said arm radially extending from said mirror support plate underneath said seat rearwardly thereof and supporting at its distal end a bracket mounted to said arm for limited pivotal motion relative to said arm; means extending upwardly from said bracket for supporting a mirror in a generally vertically disposed plane; cam means disposed on said assembly, and linkage means coupling said cam means to said bracket for pivoting said bracket responsive to the rotation of said seat for causing the face of said mirror to be retained substantially tangential to a circle having its center located forward of the axis of rotation of said seat.
Claim 13
Dependent Claim
175 words
A chair comprising: the stacked assembly of a stationary base plate, a rotatably mounted mirror support plate, a rotatably mounted seat, and bearing means disposed between said mirror support plate and said seat for causing rotation of said seat to be transmitted by said bearing means to said mirror support plate for effecting counterrotation thereof; a support arm secured with one end to said mirror support plate for motion therewith, said arm radially extending from said mirror support plate underneath said seat rearwardly thereof and supporting at its distal end a bracket mounted to said arm for limited pivotal motion relative to said arm; means extending upwardly from said bracket for supporting a mirror in a generally vertically disposed plane; cam means disposed on said assembly, and linkage means coupling said cam means to said bracket for pivoting said bracket responsive to the rotation of said seat for causing the face of said mirror to be retained substantially tangential to a circle having its center located forward of the axis of rotation of said seat.
Claim 14
Dependent Claim
19 words
A chair as set forth in claim 11, said bracket mounted for pivotal motion about a vertically disposed axis.
Claim 15
Dependent Claim
