Abstract
A seat apparatus include: a shaft rotated by a motor and operatively associated with the seat so as to move the seat; a first leg secured to the shaft and pivotably supported by the seat; a first spring, one end of which is fixedly attached to the shaft and an other end of which is fixedly attached to the seat; the first spring which biases the shift in a first direction; and a second spring, one end of which is fixedly attached to the shaft and an other end of which is fixedly attached to the seat, the second spring which biases the shaft in a second direction. The first direction opposes to the second direction.
Claims20
A seat apparatus comprising;
- a seat;
- a shaft rotatable by a motor and operatively associated with the seat so as to move the seat;
- a first leg secured to the shaft and pivotably supported by the seat;
- a first spring, one end of which is fixedly attached to the shaft and an other end of which is fixedly attached to the seat, the first spring which biases the shaft in a first direction;
- and
- a second spring, one end of which is fixedly attached to the shaft and an other end of which is fixedly attached to the seat, the second spring which biases the shaft in a second direction,
- wherein the first direction opposes to the second direction.
A seat apparatus comprising:
- a seat;
- a link mechanism operatively mounted on a stationary portion and operatively supporting the seat, the link mechanism being driven by a driving unit so that the link mechanism shifts the seat between a first position and a second position;
- a first biasing member which assists the driving unit in moving the seat from the first position to the second position;
- and
- a second biasing member which restrains the driving unit in moving the seat from the first position to the second position.
A seat apparatus comprising:
- a seat;
- a link mechanism which freely rotatably supports the seat;
- a first spring which biases the link mechanism in a first direction;
- a second spring which biases the link mechanism in a second direction, wherein the first direction is opposed to the second direction.
