Abstract
An adjustable seat system includes a pair of chairs aligned with each other so that a front side of one chair faces a backside of another of the chairs. Each of the chairs includes a seat having a plurality of legs. The seat includes a pair of lateral walls and a seat cushion positioned between the lateral walls. The seat cushion has a rear edge and a front edge. A backrest is attached to the seat. A drive mechanism is mechanically coupled to the seat cushion. The drive mechanism is actuated in a first direction to lift the rear edge upwardly or actuated in a second direction to lower the rear edge downwardly to an approximately horizontal orientation. A seat control is electrically coupled to the drive mechanism and is actuated to selectively actuate the drive mechanism in a first direction or a second direction.
Claims4
An adjustable seating system comprising:
- a pair of chairs, said chairs being aligned with each other so that a front side of one chair faces a backside of another of the chairs, each of said chairs including;
- a seat having a plurality of legs being attached thereto and extending downwardly therefrom, said seat including a pair of lateral walls and a seat cushion being positioned between said lateral walls, said seat cushion having a rear edge and a front edge;
- a backrest being attached to said seat;
- a drive mechanism being mounted to said seat and being mechanically coupled to said seat cushion, said drive mechanism being actuated in a first direction to lift said rear edge upwardly with respect to said lateral walls and to angle with respect to a horizontal plane said seat such that said seat is angled downwardly from said rear edge to said front edge, said drive mechanism being actuated in a second direction to lower said rear edge downwardly to an approximately horizontal orientation;
- a seat control being electrically coupled to said drive mechanism and being actuated to selectively actuate said drive mechanism in a first direction or a second direction;
- a shin engaging panel being attached to the backside of said seat, said shin engaging panel being pivotable with respect to said seat;
- an extension mechanism being attached to said shin engaging panel, said extension mechanism being fully positioned rearwardly of an outermost face of said shin engaging panel relative to said seat, said extension mechanism selectively extending said shin engaging panel away from said seat into a deployed position and retracting said shin engaging panel against said seat into a stored position;
- and
- a panel control being electrically coupled to said extension mechanism to actuate said extension mechanism to the deployed position or the stored position.
