Abstract
Abstract A rocking chair whose rocking action is achieved solely through a linkage mechanism rather than rocking cams conventionally employed. In one embodiment, the chair includes upholstered seat, backrest and armrests which are united in a one-piece structure mounted on a fixed base by means of the linkage mechanism. In the preferred embodiment, the base is provided with a swivel enabling the chair to swivel about a vertical axis. The linkage mechanism allows it to be mounted within the seat frame into a compact space which permits low seat styling and yet, the linkage mechanism is concealed and still functions to provide stable rocking as well as gliding action. In another embodiment, the chair is provided with a footrest and the seat is moveable relative to the swivel into a reclining position when the footrest is extended. Additionally, the backrest may be either fixed to the seat in the manner of a "one-way" recliner or moveable relative to the seat as in a "three-way" recliner chair.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
173 words
A rocking chair comprising a base, a seat and backrest structure including a seat frame having opposite side portions, and linkage means suspending the seat at said side portions from the base for rocking movement along an arc during which the seat is also displaced in a horizontal plane relative to the base, a footrest, a footrest linkage mounting the footrest relative to the seat for movement between a retracted position below the seat and an extended position projected forwardly from the seat, and means for actuating the footrest linkage to drive the footrest from the retracted to the extended position, said linkage means suspending the seat from the base includes front and rear swing arms pivoted at upper end portions thereof to the base, and linkage means connecting the swing arms to the seat, including a carrier link, said swing arms having lower portions pivotally connected with the carrier link, and wherein said linkage means connecting said swing arms to the seat includes linkage means mounting the seat to the carrier link.
Claim 2
Dependent Claim
