Abstract
A folding seat is disclosed which comprises a base structure, a seat cushion pivotally mounted to the base structure, a seat back pivotally connected to the seat cushion, first springs arranged between the seat cushion and the seat back to bias them toward each other, a second spring arranged between the seat cushion and the base structure, and a guide mechanism for causing the seat back to pivot to its upright in-use position when the seat cushion is pivoted to its horizontal in-use position. The second spring is so arranged that once the seat cushion is pivoted to a certain angular position, further pivoting of the same toward a desired position is automatically carried out thereafter.
