Abstract:
1. A vehicle seat in which a seat back pivotably mounted to a seat cushion is switched between a rearwardly tilted state in which the seat back is rearwardly tilted, a forwardly tilted state in which the seat back is forwardly tilted, and a greatly tilted state in which the seat back is tilted further forwards beyond the forwardly tilted state, comprising: a stopper that stops forward pivoting of the seat back at the position of the forwardly tilted state; first and second operation levers operable to place the seat back in the forwardly tilted state and the greatly tilted state, respectively; a stopper operation mechanism that moves the stopper in synchronization with the operation of the first operation lever; a reclining mechanism switching the seat back between a free state in which the seat back can be pivoted with respect to the seat cushion and a locked state in which the seat back cannot be pivoted with respect the seat cushion; a reclining lever that operates the reclining mechanism; and a connection lever interlocking the reclining lever and the stopper operation mechanism with each other, wherein, through operation of the first operation lever, in order to place the seat back in the forwardly tilted state, the stopper moves from a non-acting position to an acting position via the stopper operation mechanism, the non-acting position not stopping the forward pivoting of the seat back at the position of the forwardly tilted state, the acting position capable of stopping the forward pivoting of the seat back at the position of the forwardly tilted state, wherein, through the operation of the first operation lever, the seat back is placed in the free state via the stopper operation mechanism, the connection lever, and the reclining lever, and when the seat back is pivoted forwardly from the rearwardly tilted state, the reclining lever is held in a position that enables the seat back to be in the free state, and wherein a retention mechanism is provided between the stopper operation mechanism and the reclining lever, and when the first operation lever is operated and the reclining lever is held in the position that enables the seat back to be in the free state, the retention mechanism prevents the connection lever from moving in relation to the reclining lever, and the connection lever maintains the stopper at the acting position via the stopper operation mechanism.
