An operation mechanism of a side support apparatus adapted to be accommodated in a right and left side support portions provided at a seatback and being movable between a support position and an open position, includes a support structure including a pulley and being movable between the open position and the support position, a first fixing portion including a first guide portion and a second guide portion and fixedly provided at a seatback member, and a drive cable being fixedly attached to the first fixing portion at a first end portion of the drive cable and being engaged with the pulley at an intermediate of the drive cable. The pulley is pushed by a tensile force generated at the drive cable by pulling the drive cable so that the support structure is movable relative to the first fixing portion in a direction toward the support position.

Operation mechanism of side support apparatus and side support apparatus using same for vehicular seat

To reduce the gap between the floor portion of a cargo compartment in a vehicle and a seat back when the cargo compartment is enlarged by forwardly bringing down the seat back of the passenger seat adjoining the driver or a rear seat, a vehicular seat structure is designed so that when the seat back of the rear seat is forwardly brought down by a predetermined angle, a pin provided on a bell crank is brought into contact with an upper end portion of a second link, and the second link is rotated. As a result, a first link is pulled upward and the bell crank is rotated so that the rear end portion of a slide lock lever is rotated in the direction causing the slide lock to be released. Thereafter, when the seat back is brought down further forwardly, a connecting member which can be in the form of one or more belts moves the seat rearwardly. A stopper contacts the first link and the movement of the seat is stopped.
