Abstract
Abstract Two embodiments of a multi-position reclining chair assembly wherein both embodiments include a metal plate like support member, a metal plate-like seat member, a leg rest and attendant linkage, whereby the seat member moves forwardly relative to the support member in moving to a reclining position as the leg rest is extended so that no room is required behind the chair to accommodate reclining movement of the seat back. In one embodiment a manually graspable handle and associated linkage is utilized to move the assembly between an upright position and a fully reclined position, whereas in the other embodiment the assembly is moved between the upright and fully reclined positions by applying force to the seat member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
214 words
A multiple position reclining chair assembly comprising: support means, seat means, a leg rest member, leg rest mounting linkage mounting said leg rest member for movement between a collapsed stored position and an extended leg supporting position and, linkage means operatively interconnecting said support means and said seat means and said leg rest mounting linkage for moving said seat means from an upright position forwardly relative to said support means to a fully reclined position while at the same time actuating said mounting linkage to move said leg rest member to said extended leg supporting position, said linkage means including first and second links with each link pivotally connected to said support means and said seat means respectively, said mounting linkage including a plurality of pivotally interconnected and crossed links with one of said links being a control link pivotally connected adjacent its lower end to another of said crossed links and pivotally connected intermediate its ends to one of said first link and said seat means and said linkage means including a connecting link pivotally connected to the upper end of said control link and pivotally connected to said support means for extending said leg rest member to said leg supporting position as said seat means moves forwardly relative to said support means.
Claim 2
Dependent Claim
214 words
A multiple position reclining chair assembly comprising: support means, seat means, a leg rest member, leg rest mounting linkage mounting said leg rest member for movement between a collapsed stored position and an extended leg supporting position and, linkage means operatively interconnecting said support means and said seat means and said leg rest mounting linkage for moving said seat means from an upright position forwardly relative to said support means to a fully reclined position while at the same time actuating said mounting linkage to move said leg rest member to said extended leg supporting position, said linkage means including first and second links with each link pivotally connected to said support means and said seat means respectively, said mounting linkage including a plurality of pivotally interconnected and crossed links with one of said links being a control link pivotally connected adjacent its lower end to another of said crossed links and pivotally connected intermediate its ends to one of said first link and said seat means and said linkage means including a connecting link pivotally connected to the upper end of said control link and pivotally connected to said support means for extending said leg rest member to said leg supporting position as said seat means moves forwardly relative to said support means.
