Abstract
The invention is intended to improve operability of a seat unit in a process of turning it from an approximately horizontal storage position to a seating position. An upper end of a seatback (SB) in its seating position and a rear end of a seat cushion (SC) are joined together by a string (), and two helical springs (biasing members) are provided at a forward portion of the seat cushion (SC). The first helical spring () exerts an upward biasing force which is smaller than the weight of the seat cushion (SC) against the seat cushion (SC), while the second helical spring () exerts an upward biasing force which is larger than the weight of the seat cushion (SC) against the seat cushion (SC). With this arrangement, a rear portion of the seat cushion (SC) is lifted when the seat is turned from the seating position to the storage position, and a small force is needed for lifting the seat cushion (SC) when it is turned in a reverse direction. The seat unit can be brought to the seating position by a single action since the seatback (SB) and the seat cushion (SC) are joined to each other by the string ().
