Abstract
Embodiments of the present invention disclose a lift chair assembly for assisting a user to transition between sitting and standing. The assembly includes a frame body, a backrest member coupled to the frame body, a seat member coupled to the frame body and configured to pivot about an axis relative to the frame body independently from the backrest member such that the seat member pivots between a neutral position and an elevated position, a motor that selectively pivots the seat member, and a controller that selectively engages the motor to pivot the seat member.
Claims17
A chair assembly, comprising:
- a frame body;
- a backrest member and a pair of armrests coupled to the frame body;
- a base member including a pair of track members defining a length and a swivel plate, the swivel plate configured to longitudinally translate along the length relative to the base member via the pair of track members;
- a swivel mechanism defining a vertical axis, the swivel mechanism coupled to the frame body and the swivel plate, the swivel mechanism allowing the frame body to rotate about the vertical axis relative to the base member;
- a seat member pivotally coupled to the frame body and configured to pivot about a horizontal axis relative to the frame body independently from the backrest member and the pair of armrests such that the backrest member and the pair of armrests fail to move when the seat member is pivoting, the seat member pivoting between a neutral position and an elevated position;
- a motor in mechanical communication with the frame body and the seat member, wherein the motor selectively pivots the seat member about the horizontal axis relative to the frame body;
- and
- a controller in electrical communication with the motor, wherein the controller selectively engages the motor to pivot the seat member about the horizontal axis;
- wherein the seat member is configured to be pivoted between the neutral position and the elevated position at any longitudinal position and at any rotational orientation of the frame body relative to the base member.
