Abstract
A modular wall proximity reclining/tilt chair and method for assembling it are disclosed. The modular wall proximity reclining/tilt chair includes a simplified actuation mechanism which significantly reduces system complexity and weight while providing improved comfort to the seat occupant. The construction is such that the pre-assembled actuation mechanism is integrally suspended from and interdependent with box-like modular frame components. In this manner, the frame components can be upholstered prior to final assembly with the actuation mechanism.
Claims20
A method for assembling a wall proximity reclining chair comprising the steps of:
- providing an actuation mechanism;
- suspending said actuation mechanism between a pair of side frame members;
- interconnecting cross rail members with said side frame members to define a chair frame within which said actuation mechanism is operably supported;
- providing a seat assembly having a seat, a seat back, and swing link means for pivotally interconnecting said seat back and said seat;
- connecting said swing link means to said side frame members for suspending said seat assembly therebetween, said swing link means operable to permit reclining movement of said seat assembly with respect to said chair frame between an upright position and a reclined position in response to pressure applied by a seat occupant to said seat back;
- connecting bearing linkages to a lower portion of said side frame members, said bearing linkages having wheel means secured thereon;
- providing a stationary base assembly having track means;
- and
- inserting said wheel means of said bearing linkages into said track means, whereby said chair frame is supported for translation movement relative to said base assembly in response to reclining movement of said seat assembly.
A method of modular assembly for a wall proximity reclining chair, said method comprising the steps of:
- providing an actuation mechanism having first and second shafts;
- providing a pair of side frame members;
- inserting opposite ends of said first shaft into a first set of alignable bores formed in said side frame members for suspending said first shaft therebetween;
- inserting opposite ends of said second shaft into a second set of alignable bores formed in said side frame members for suspending said second shaft therebetween;
- connecting front and rear cross frame members between said side frame members to define a chair frame, said actuation mechanism being integrally retained within said chair frame;
- providing a seat assembly having a seat, a seat back, and swing link means for pivotally interconnecting said seat back and said seat;
- connecting said swing link means to a third set of alignable bores formed in said side frame members for suspending said seat assembly therebetween, said swing link means operable to permit reclining movement of said seat assembly with respect to said chair frame between an upright position and a reclined position in response to pressure applied by a seat occupant to said seat back;
- connecting guide means between said second shaft and said seat for guiding and limiting fore and aft movement of said seat with respect to said second shaft in response to reclining movement of said seat assembly;
- connecting bearing linkages to a lower portion of said side frame members, said bearing linkages having wheel means secured thereon;
- providing a stationary base assembly having track means;
- inserting said wheel means of said bearing linkages into said track means for permitting translational movement of said chair frame relative to said base assembly in response to reclining movement of said seat assembly;
- connecting push linkages that are suspended between said first shaft and said guide means to said base assembly for cooperating with said swing link means to cause said translational movement of said chair frame;
- supporting a leg rest assembly from said first and second shafts for movement between a retracted position and an extended position in response to selective rotation of said first shaft, said movement of said leg rest assembly being independent from said reclining movement of said seat assembly;
- and
- connecting tilt linkages between said first shaft and said bearing linkages for tilting said chair frame relative to said base assembly in response to movement of said leg rest assembly.
A method for assembling a wall reclining chair comprising:
- providing means defining a chair frame having side frame members interconnected with cross rail members;
- suspending an actuation mechanism between said side frame members;
- pivotally interconnecting a seat and seat back;
- operably connecting said interconnected seat and seat back to said chair frame for reclining movement;
- providing a base assembly, said base assembly including support means for supporting said chair frame for translational movement in response to reclining movement of said seat assembly;
- and
- supporting said chair frame on said support means.
