Automatically adjustable seat
Automatically adjustable seating apparatus are described. The automatically adjustable seating apparatus include first and second seat bottom portions that at least one of which is moveable. The first and/or second seat bottom portions are moveable by automatic adjusters that alter the position of a seat bottom portion between a retracted position and an extended position. When the moveable seat bottom portion or portions are in their retracted position, the automatically adjustable seating apparatus is configured as two seats back-to-back, and when the seat bottom portion or portions are in their extended positions, the automatically adjustable seating apparatus forms a substantially flat surface.
1. An automatically adjustable seating apparatus comprising:
a frame;
a first seat bottom portion slideably attached to the frame;
an automatic adjuster that is attached to the first seat bottom portion and that alters a position of the first seat bottom portion between a first seat bottom portion retracted position and a first seat bottom portion extended position, wherein the position is altered by the automatic adjuster independent of manual adjustment by a person; and
a second seat bottom portion, a position of the second seat bottom portion being fixed,
wherein when the first seat bottom portion is in its retracted position, the automatically adjustable seating apparatus is configured as two seats back-to-back, and when the first seat bottom portion is in its extended position, the automatically adjustable seating apparatus forms a substantially flat surface.
2. The automatically adjustable seating apparatus of claim 1 , further comprising:
a first seat back having an upper portion and a lower portion, the lower portion pivotally attached to the first seat bottom portion; and
a second seat back having an upper portion and a lower portion, the lower portion pivotally attached to the second seat bottom portion and the upper portion pivotally attached to the upper portion of the first seat back.
3. The automatically adjustable seating apparatus of claim 1 , further comprising a controller operatively interconnected with the automatic adjuster for controlling the position of the first seat bottom portion, the first seat back and the second seat back, wherein the automatic adjuster includes at least one of an automatically driven or actuated adjuster.
4. The automatically adjustable seating apparatus of claim 3 , wherein the controller is capable of adjusting the automatic adjuster to maintain a position between the retracted and extended positions.
5. The automatically adjustable seating apparatus of claim 3 , wherein the controller has selectable pre-selected positions between the retracted and extended positions, and wherein the automatic adjuster is a motorized adjuster.
6. The automatically adjustable seating apparatus of claim 1 , wherein the automatic adjuster is electrically driven.
7. The automatically adjustable seating apparatus of claim 1 , wherein the first seat bottom portion is attached to a first seat frame and the first seat frame is slideably attached to the frame.
8. The automatically adjustable seating apparatus of claim 1 , wherein the second seat bottom portion is attached to a second seat frame.
9. The automatically adjustable seating apparatus of claim 1 , further comprising an intermediate position between the first seat bottom portion retracted position and the first seat bottom portion extended position.
10. An automatically adjustable seating apparatus comprising:
a frame;
a first seat bottom portion slideably attached to the frame;
an automatic adjuster that moves the first seat bottom portion between a retracted position and an extended position without manual adjustment of the first seat bottom portion by an operator;
a second seat bottom portion attached in a fixed position to the frame;
a first seat back having an upper portion and a lower portion, the lower portion pivotally attached to the first seat bottom portion; and
a second seat back having an upper portion and a lower portion, the lower portion pivotally attached to the second seat bottom portion and the upper portion pivotally attached to the upper portion of the first seat back,
wherein the first seat bottom portion is moveable from the retracted position to the extended position in a linear direction away from the second seat bottom portion a distance sufficient to allow the first and second seat backs to form a substantially flat surface.
11. The automatically adjustable seating apparatus of claim 10 , further comprising a controller operatively interconnected with the automatic adjuster for controlling the position of the first seat bottom portion.
12. The automatically adjustable seating apparatus of claim 11 , wherein the controller is capable of adjusting the automatic adjuster to maintain a position between the retracted and extended positions.
13. The automatically adjustable seating apparatus of claim 11 , wherein the controller has selectable pre-selected positions between the retracted and extended positions.
14. The automatically adjustable seating apparatus of claim 10 , wherein the automatic adjuster is electrically driven.
15. The automatically adjustable seating apparatus of claim 10 , wherein the first seat bottom portion is attached to a first seat frame and the first seat frame is slideably attached to the frame.
16. The automatically adjustable seating apparatus of claim 10 , further comprising an intermediate position between the first seat bottom portion retracted position and the first seat bottom portion extended position.
17. An automatically adjustable seating apparatus comprising:
a first seat bottom portion, the first seat bottom portion moveable by an automatic adjuster when an external signal is received to alter a position of the first seat bottom portion between a retracted position and an extended position;
a first seat back having an upper portion and a lower portion, the lower portion pivotally attached to the first seat bottom portion;
a fixed second seat bottom portion;
a second seat back having an upper portion and a lower portion, the lower portion pivotally attached to the second seat bottom portion and the upper portion pivotally attached to the upper portion of the first seat back; and
a controller operatively interconnected with the automatic adjuster for controlling the position of the first seat bottom portion relative to the second seat bottom portion,
wherein when the first seat bottom portion is in the retracted position the automatically adjustable seating apparatus is configured as two seats back-to-back, and when the first seat bottom portion is in the extended position the automatically adjustable seating apparatus forms a substantially flat surface.
18. An automatically adjustable seating apparatus comprising:
a frame;
a first seat comprising a first seat bottom that is pivotably attached to a first seat back, the first seat bottom slidable relative to the frame;
a second seat comprising a second seat bottom that is pivotably attached to a second seat back, the second seat back pivotably attached to the first seat back, the second seat bottom fixed relative to the frame; and
a motorized automatic adjuster coupled to the first seat bottom, wherein activation of the motorized automatic adjuster drives the first seat bottom relative to the frame between a fully retracted position and a fully extended position without any manual pushing or pulling of the automatically adjustable seating apparatus,
wherein while the first seat bottom is in the fully retracted position the automatically adjustable seating apparatus is configured as two seats back-to-back, and while the first seat bottom is in the fully extended position the automatically adjustable seating apparatus is configured as a substantially flat surface.
19. The automatically adjustable seating apparatus of claim 18 , further comprising a controller with one or more switches for electrically activating the motorized automatic adjuster to drive the first seat bottom relative to the frame.
