Chair
First Claim
1. A reclining chair comprisinga pedestal-type-swivel base having a U-shaped frame supported on a vertical post, said frame having upwardly extending and spaced apart sides,a pair of coaxial axles extending horizontally one from each side of the frame and each axle carrying a bracket, said brackets being pivotally supported for movement about the axes of the axles,a seat and back mounted as an assembly on the brackets with the seat and back in fixed relationship to one another and pivotal with the brackets between upright and reclined positions,a brake mechanism have a first brake element mounted on at least one of the axles and movable with the bracket as the bracket pivots with the seat and back assembly about the axes of the axles as the assembly moves between upright and reclined positions,a second brake element connected to the side of the frame and positioned to engage and disengage the first brake element to selectively prevent and permit pivotal movement of the brackets and seat and back assembly about the axes of the axles,an actuator connected to the brake mechanism for operating the brake mechanism,a footrest pivotally mounted on the seat,and a linkage assembly connected to the seat, footrest and frame for raising the footrest to an operative position as the seat and back assembly moves from the upright to the reclined position and lower the footrest to an inactive position as the seat and back assembly moves back to the upright position.

Abstract
A swivel type chair that functions as both a high back desk chair and a recliner. The seat and backrest pivot as a unit on the base between upright and reclined positions and a footrest is movable pivotally with respect to the seat and is tucked underneath the seat when the chair is in the upright position to function as a desk chair and elevates to an extended position automatically when the chair is moved to the reclined position. A brake mechanism is carried on the chair for locking the seat and backrest in any selected position between the upright and reclined positions.

7. A reclining chair comprising
a base and a body support assembly pivotally mounted for rocking movement between upright and reclined positions about a fixed horizontal axis on the base, said body support assembly having a seat and back which remain in fixed relationship to one another during said rocking movement, means joining the body support assembly on the base enabling the assembly to move axially with respect to the fixed horizontal axis on the base, a brake mechanism connected to the base and body support assembly, said brake mechanism including a first brake member fixed to and movable pivotally and axially with the body support assembly on the base and a second brake member mounted on the frame, said second brake member being movable parallel to the pivotal axis on the base, and an actuator connected to the brake mechanism for selectively causing the second brake member to engage and disengage the first brake member to prevent and permit rocking motion of the body support assembly about the axis between upright and reclined positions.

12. A reclining chair comprising
a base and a body support assembly pivotally mounted for rocking movement between upright and reclined positions about a fixed horizontal axis on the base, said body support assembly having a seat and back which remain in fixed relationship to one another during said rocking movement, a brake mechanism connected to the base for releasably locking the body support assembly in selected positions between the upright and reclined positions, said brake mechanism including a brake disk connected to and pivotal with the body support assembly on the base, a brake block mounted on the base and having a friction surface positioned to engage the brake disk, and an actuator mounted on the base and connected to the block for moving the friction surface in and out of contact with the disk to lock and release the body support assembly for pivotal movement about the axis, a footrest pivotally connected to the seat and movable between a stored position wherein it is disposed under the seat inwardly of the front edge of the seat when the body support assembly is in the upright position and an extended position wherein it is disposed in a substantially horizontal position extending forwardly from the front edge of the seat when the body support assembly is in an extreme reclined position.
