<P>PROBLEM TO BE SOLVED: To provide a vehicle seat, in which a folding amount of an upper frame of a seat back becomes gradually larger from a normal use position to a backward tilting position, and the folding amount of the upper frame becomes gradually smaller from the backward tilting position to a flat position. <P>SOLUTION: A back frame 21 including a lower frame 26 connected to the rear section of a cushion frame 41, and the upper frame 22 connected to the lower frame 26 so as to be folded in back and forth directions, is constituted in a form bent in the middle. An interlocking link 71 is arranged between the cushion frame 41 and the upper frame 22. The folding amount of the upper frame 22 of the seat back 20 becomes gradually larger from the normal use position toward the back tilting position where the center line L of the interlocking link 71 is positioned on the connection center P of a rear section of the cushion frame 41 and the lower frame 26, and the folding amount of the upper frame 22 becomes smaller toward the flat position where the seat back 20 is rearward laid down. <P>COPYRIGHT: (C)2012,JPO&INPIT |
