Seating unit having a horizontally positionable seat section
First Claim
1. A seating unit having a movable seat, said unit comprising:
- a support frame;
a backrest member extending upward from said support frame, said movable seat disposed on said support frame such that the entirety of said seat may be displaced within a horizontal plane outward from said support frame to one of a plurality of extended positions relative to said support frame;
a locking assembly to selectively engage said seat to said support frame to thereby secure said seat to said support frame after displacing said seat to one of a plurality of extended positions;
a first actuator handle, affixed to said support frame;
a second actuator handle affixed to said support frame and spaced from said first actuator handle;
an actuator assembly disposed on said support frame, said actuator assembly in communication with said locking assembly, whereby upon activation of said actuator assembly, said locking assembly engages said seat to said support frame;
a first cable extending between said first actuator handle and said actuator assembly;
a second cable extending between said second actuator handle and said actuator assembly;
whereby (i) upon activating said first actuator handle, said first cable is tensioned thereby activating said actuator assembly to engage said seat to said support frame, or (ii) upon activating said second actuator handle, said second cable is tensioned thereby activating said actuator assembly to engage said seat to said support frame.

Abstract
A seating unit with at least one independently movable seat sections, is disclosed which includes a main frame arranged for support of a back rest in fixed relation thereto and one or more seat frames for supporting the seat sections. Support tracks slidably support each seat frame with respect to the main frame. Each seat frame can be moved from a retracted position to an extended position in relation to the main frame. A locking device secures a respective seat frame in relation to the main frame in a plurality of positions between the retracted position and the extended position. Numerous seat frame embodiments are disclosed. In addition, a unique cable-based actuation assembly is described for manually positionable seat configurations. Electrically powered versions are also disclosed in which one or more motors are incorporated in the seating unit and provide powered extension and retraction of one or more individual seats. Remote control systems for electrically powered drives are also disclosed.

10. A seating unit including:
-
a stationary base;
a linearly positionable seat movably coupled to said stationary base, said seat movable within a horizontal plane, and movable between a fully retracted position and a fully extended position in which at least a portion of said seat is cantilevered out from said base, said seat being selectively positionable to one of a plurality of positions between said fully retracted position and said fully extended position;
a locking assembly to selectively engage said seat to said stationary base after positioning said seat to one of a plurality of positions;
a first actuator disposed at a first end of said stationary base;
a second actuator disposed at a second end of said stationary base;
an actuator assembly in operable engagement with both said first actuator and said second actuator, and said locking assembly whereby upon activation of either said first actuator or said second actuator, said actuator assembly engages said locking assembly to thereby release said seat from said stationary base and allow movement of said seat with respect to said stationary base. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
