Examination chair with lifting and tilting mechanism

An electrically powered tilt and lift chair for use in medical and dental procedures, the chair comprising:

• a patient support including seat and back support surfaces attached in fixed relation with respect to one another for accommodating a patient and including first and second curved roller tracks;
• a base including a lift mechanism with a raising and lowering element for raising and lowering the patient support;
• a seat support member connected to the patient support below the seat support surface and further connected to the raising and lowering element of the lift mechanism;
• rollers operatively coupled with the seat support and connected for rolling movement along the first and second curved roller tracks;
• a linear drive member connected to said patient support for pivotal movement behind said back support surface;
• a first electric motor coupled to said linear drive member, for moving the linear drive member in a manner that drives the patient support in an arcuate path along the rollers to simultaneously tilt the seat and back support surfaces while said seat and back support surfaces are in the fixed relation;
• and
• a second electric motor coupled with the lift mechanism for allowing raising and lowering of the patient support.
