Abstract
Abstract Improvements in a rocker recliner chair which permit the backrest to be moved to an initial, relatively slight reclining position without having to first extend the footrest from retracted to extended position, however, in order to continue to move the backrest into a full recline position into an advanced or full recline position, the footrest must be extended which is effected through a manually operated handle connected to the footrest linkage. The foregoing sequencing and control is achieved by a linkage interconnecting the footrest linkage and the linkage which serves to mount the seat relative to the base which, in the preferred embodiment of the invention, includes a rocker frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
256 words
A reclining chair including a base, a seat, seat linkage mounting the seat for movement relative to the base, a backrest, backrest linkage mounting the backrest to and for movement relative to the seat between a generally upright position and a number of reclining positions, a footrest, footrest linkage mounting the footrest to the seat for movement between a retracted position adjacent the seat and an extended position projected forwardly from the seat, sequencing and control linkage connected between the footrest linkage and the seat for permitting the backrest and the seat to be moved to an initial reclining position relative to the base while the footrest is in retracted position but preventing further movement of the backrest to a reclining position advanced from said initial position unless the footrest is moved to extended position, and wherein said sequencing and control linkage includes a first control link pivoted relative to the seat, a second control link pivoted to the footrest linkage and a lost motion connecting means interconnecting said first and second control links, and wherein said lost motion connecting means includes a pin fixed to one of said control links and a slot on the other of said control links receiving said pin, the pin being movable in said slot, and wherein said first control link is also pivotally connected relative to said base, and wherein said footrest linkage includes a footrest mounting link pivotally mounted relative to the seat linkage and wherein said second control link is pivotally connected to said footrest mounting link.
Claim 2
Dependent Claim
256 words
A reclining chair including a base, a seat, seat linkage mounting the seat for movement relative to the base, a backrest, backrest linkage mounting the backrest to and for movement relative to the seat between a generally upright position and a number of reclining positions, a footrest, footrest linkage mounting the footrest to the seat for movement between a retracted position adjacent the seat and an extended position projected forwardly from the seat, sequencing and control linkage connected between the footrest linkage and the seat for permitting the backrest and the seat to be moved to an initial reclining position relative to the base while the footrest is in retracted position but preventing further movement of the backrest to a reclining position advanced from said initial position unless the footrest is moved to extended position, and wherein said sequencing and control linkage includes a first control link pivoted relative to the seat, a second control link pivoted to the footrest linkage and a lost motion connecting means interconnecting said first and second control links, and wherein said lost motion connecting means includes a pin fixed to one of said control links and a slot on the other of said control links receiving said pin, the pin being movable in said slot, and wherein said first control link is also pivotally connected relative to said base, and wherein said footrest linkage includes a footrest mounting link pivotally mounted relative to the seat linkage and wherein said second control link is pivotally connected to said footrest mounting link.
Claim 3
Dependent Claim
203 words
A reclining chair including a base, a seat, seat linkage mounting the seat for movement relative to the base, a backrest, backrest linkage mounting the backrest to and for movement relative to the seat between a generally upright position and a number of reclining positions, a footrest, footrest linkage mounting the footrest to the seat for movement between a retracted position adjacent the seat and an extended position projected forwardly from the seat, the footrest linkage including means for extending and retracting the footrest independently of the backrest, sequencing and control linkage connected between the footrest linkage and the seat for permitting the backrest and the seat to be moved to an initial reclining position relative to the base while the footrest is in retracted position but preventing further movement of the backrest to a reclining position advanced from said initial position unless the footrest is moved to extended position, and wherein said sequencing and control linkage includes a first control link pivoted relative to the seat, a second control link pivoted to the footrest linkage and a lost motion connecting means interconnecting said first and second control links, and wherein said first control link is also pivotally connected relative to said base.
Claim 4
Dependent Claim
203 words
A reclining chair including a base, a seat, seat linkage mounting the seat for movement relative to the base, a backrest, backrest linkage mounting the backrest to and for movement relative to the seat between a generally upright position and a number of reclining positions, a footrest, footrest linkage mounting the footrest to the seat for movement between a retracted position adjacent the seat and an extended position projected forwardly from the seat, the footrest linkage including means for extending and retracting the footrest independently of the backrest, sequencing and control linkage connected between the footrest linkage and the seat for permitting the backrest and the seat to be moved to an initial reclining position relative to the base while the footrest is in retracted position but preventing further movement of the backrest to a reclining position advanced from said initial position unless the footrest is moved to extended position, and wherein said sequencing and control linkage includes a first control link pivoted relative to the seat, a second control link pivoted to the footrest linkage and a lost motion connecting means interconnecting said first and second control links, and wherein said first control link is also pivotally connected relative to said base.
Claim 5
Dependent Claim
42 words
The chair defined in claim 2 wherein said lost motion connecting means includes a pin fixed to one of said control links and a slot on the other of said control links receiving said pin, the pin being movable in said slot.
Claim 6
Dependent Claim
36 words
The chair defined in claim 2 wherein said footrest linkage includes a footrest mounting link pivotally mounted relative to the seat linkage and wherein said second control link is pivotally connected to said footrest mounting link.
