Vehicle seats

摘要

A double folding mechanism of a seat (1) of a vehicle can fold a seat cushion (2) from a space on a floor (F) and fold a seat back (3) into the space, thereby changing the seat from its use condition to its retracted condition. The double folding mechanism can include a first connecting mechanism (20) connecting the seat cushion (2) and the floor (F) and a second connecting mechanism (30) connecting the seat back (3) and the floor (F). The second connecting mechanism can control the rotational speed of the seat back (3) such that the seat back (3) can enter inside a rotational trajectory of a rear end of the seat cushion (2) after the seat cushion (2) comes out of a rotational trajectory of an upper end portion of the seat back (3). The double folding mechanism can change the seat (1) from the use condition to the retracted condition in one operation.
