Abstract

A reclining chair in which the backrest and seat are reclined, and the retractable footrest is extended, by the descent of the seat from the normal sitting position under the weight of the occupant and at the occupant'"'"'s election, and in which all parts are restored to the sitting position by the occupant'"'"'s forcible retraction of the footrest by flexing his knees.

Claims

1. A reclining chair having

a normally stationary chair frame with an upstanding back portion,

a backrest pivotally suspended from the back portion of the chair frame for forward swinging movement of the lower end of the backrest from a sitting position to a reclining position, and vice versa, and

a seat member movably connected to the lower end of the backrest, and slidably and pivotally supported by the chair frame near the front of the chair frame;

the improvement wherein

the chair is also provided with a retractable footrest movable from a stowed position beneath the seat member to an extended position forwardly thereof to support the legs of the occupant, and a drive linkage beneath the seat member to extend and retract the footrest when actuated;

the movable connection between the seat member and backrest comprises a lever which is pivoted to both of them and connected to said drive linkage, and is oriented in said sitting position to utilize the weight of the occupant to cause the rear end of the seat member to descend and thereby to advance the lower end of the backrest relative to the seat member and to actuate the drive linkage to extend the footrest, the rear end of said seat member being conversely raisable by the forcible retraction of the footrest; and

means capable of being disabled by the occupant is provided to prevent the descent of the rear end of the seat member from the sitting position.

2. The improvement of claim 1 wherein the lever extends rearwardly and upwardly from the seat member to the backrest in said sitting position and is provided with a stop engageable with one of the seat member and backrest to limit the drop of the seat, further forward movement of the seat resulting in further recline of the backrest relative to the seat about the pivotal connection of the lever to the other one of said seat member and backrest.

3. The improvement of claim 1 wherein said means provided to prevent the descent of the rear end of the seat member from the sitting position is a shelf member on the chair frame positioned for the direct transfer of load from the seat member to the shelf when the chair is in the sitting position, and from which the seat member is disengageable by the occupant by thrusting the seat forward with concommitant rearward pressure of the shoulders upon the backrest.

4. The improvement of claim 3 wherein the shelf member has an extended downwardly and forwardly sloped surface, and the transfer of load from the seat member to said shelf member is made by a roller journalled on the back of the seat member and engageable with said shelf member.

5. The improvement of claim 2 in accordance with claim 4 wherein the lever pivoted to the backrest and seat member and connected to the drive linkage extends downwardly from its pivotal connection to the seat member to its connection to the footrest drive linkage and actuates said drive linkage to extend the footrest by hauling rearwardly on said drive linkage when the seat member descends, and the forcible retraction of the footrest causes said drive linkage to haul forwardly on said lever to elevate the seat and retract the lower end of the backrest, and wherein a spring is connected between the chair frame and the downward extension of said lever so as to be loaded by said further forward movement of the seat to maintain the footrest firmly extended.

6. The improvement of claim 1 wherein

the chair frame is supported above the floor by means including a rear leg structure movably mounted on the chair frame to raise and lower the back of the chair frame to alter the pitch of the frame, and

the backrest is connected to the rear leg structure to lower the back of the chair frame as the lower end of the backrest moves forward.

7. The improvement of claim 6 wherein the rear leg structure is movable upwardly into the chair frame and the connection thereof to the backrest comprises a link connection between them, said link connection and backrest constituting a toggle between the rear leg structure and the upstanding back portion of the chair frame.

8. The improvement of claim 1 wherein the chair frame is supported above the floor by means including a rear leg structure movably mounted on the chair frame for movement into the frame to tilt the chair frame rearwardly, and a link connecting the rear leg structure to the backrest in a forwardly-breaking toggle between the rear leg structure and the upstanding back portion of the chair whereby the forward and upward movement of the lower end of the backrest and the rear end of the seat occasioned by forward movement of the seat into the reclining position is accompanied by the lowering of the back portion of the chair frame.

11. The improvement of claim 1 wherein said means provided to prevent the descent of the rear end of the seat member comprises inter-engageable latch means between two elements of the chair which experience relative movement upon the descent of the rear end of the seat, and means operable by the occupant is provided to release said latch means.

9. In a reclining chair having

a normally stationary chair frame, and

a body support including a seat and a backrest movably mounted on the chair frame for movement between a sitting position and a reclining position;

the inclusion by said chair frame of a rear leg structure movably mounted on the chair frame to raise and lower the back of the chair frame to alter the pitch of the chair frame, and

a connection between the body support and the rear leg structure activated by the movement of the body support toward the reclining position on the chair frame to lower the back of the chair frame, and activated by reverse movement of the body support into the sitting position thereon to raise the back of the chair frame.

10. The mechanisms of claim 9 wherein the chair is also provided with a retractable footrest movable from a stowed position beneath the seat to an extended position forwardly thereof to support the legs of the occupant, and a driving connection between the footrest and body support for extending the footrest by movement of the body support toward the reclining position and for righting the body support and raising the back of the chair frame by the retraction of the footrest into the stowed position.
