Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
233 words
Seating apparatus comprising: first and second side frame members and a back; first and second brackets connected respectively to said first and second side frame members; footrest mounting means movably coupled to said brackets; one pair of elongated support members mounted on said brackets; mesns pivotally coupling said support members to said footrest mounting means; said support members being linearly movable on said brackets in a direction away from said back to move a portion of said footrest mounting means forward on said seating apparatus; another pair of elongated support members mounted on said brackets and linearly movable thereon away from and twoard said back, and pivotally connected to said footrest mounting means and thereby providing the movable coupling of said footrest mounting means to said brackets; motor drive means drivingly connected to said support members of said one pair for drive thereof away from and toward said back; motor control means coupled to said motor drive means and operable by an occupant of the seating apparatus to move said footrest mounting means portion forward and backward on said seating apparatus; said support members being channel sections mounted to said bracket by rollers, the support members of said another pair being parallel to and above the support members of said one pair, said pivotal coupling means including links pinned to said footrest mounting means and to said channel sections of said one pair.
Claim 2
Dependent Claim

Seating apparatus comprising: first and second side frame members and a back; first and second brackets connected respectively to said first and second side frame members; footrest mounting means movably coupled to said brackets; one pair of elongated support members mounted on said brackets; mesns pivotally coupling said support members to said footrest mounting means; said support members being linearly movable on said brackets in a direction away from said back to move a portion of said footrest mounting means forward on said seating apparatus; another pair of elongated support members mounted on said brackets and linearly movable thereon away from and twoard said back, and pivotally connected to said footrest mounting means and thereby providing the movable coupling of said footrest mounting means to said brackets; motor drive means drivingly connected to said support members of said one pair for drive thereof away from and toward said back; motor control means coupled to said motor drive means and operable by an occupant of the seating apparatus to move said footrest mounting means portion forward and backward on said seating apparatus; said support members being channel sections mounted to said bracket by rollers, the support members of said another pair being parallel to and above the support members of said one pair, said pivotal coupling means including links pinned to said footrest mounting means and to said channel sections of said one pair.
Claim 3
Dependent Claim
101 words
The apparatus of claim 1 wherein said footrest mounting means includes: a footrest mount with footrest secured thereto, said mount being pinned to said links; a mount holder pivotally connected to said support members of said another pair; low friction slide means connecting said footrest mount to said mount holder and accommodating linear movement of said footrest mount relative to said mount holder for horizontal extension of said footrest mount upon termination of linear movement of said channel sections of said another pair away from said back as the channel sections of said one pair continue movement away from said back.
