The first and second driven gears are fixed coaxially with each other and engaged with the first and second driving gears, respectively. Two driving gears are arranged at the two sides of the worm gear symmetrically, and two driven gears are also arranged at the two sides of the worm gear symmetrically, which results in a compact structure and reduced volume of the driving device.

A restricting structure that restricts an allowable adjustment range of a backrest angle of a seatback is formed by a surface abutment structure of a bracket provided on the seatback, and an additional stopper provided on a seat cushion. The additional stopper is joined to a lower arm in a state positioned by a positioning hole in the additional stopper being fit onto a positioning pin that is integrated with the lower arm. A plurality of arrangement positions of the additional stopper are able to be selected by providing the positioning pin in a plurality of locations with respect to the lower arm along a path of a specific location along which additional stopper moves with respect to the lower arm, when the backrest angle of the seatback is changed while the additional stopper is surface abutted against, and temporarily fixed to, the bracket.

A vehicle seat may have height-adjustment kinematics where the kinematics may have a four-joint arrangement and an adjustment arm. The four-joint arrangements may have a base, a side part, a front swing arm and a rear swing arm as transmission elements of the four-joint arrangement. A first revolute joint may connect the base in a pivotable manner to the rear swing arm, a second revolute joint may connect the rear swing arm in a pivotable manner to the side part, a third revolute joint may connect the side part in a pivotable manner to the front swing arm, and a fourth revolute joint may connect the front swing arm in a pivotable manner to the base. Each of the two four-joint arrangements can be adjusted by one of the two adjustment arms, and a drive device, having exactly one transmission motor, drives the two adjustment arms.

Provided is a reclining device that achieves effective prevention of abnormal sound while permitting a clearance to exist between a cam and a connecting rod. A reclining device includes: a pair of reclining mechanisms each having an internal gear and a cam; a connecting rod coaxially coupled to the cam and being rotatable together with the cam; and a resin bush having a fit hole to receive a fitting part at a portion adjacent to each end of the connecting rod. The resin bush is placed in a bush insertion hole in contact with an inner surface of the bush insertion hole of the internal gear to retain the connecting rod at such a position to the cam that a clearance exists between an inner surface of a rod insertion hole of the cam and an outer surface of the connecting rod.

A seatback adjustment assembly may include a recliner heart, an attachment plate, and a lever. The recliner heart is operable in an unlocked state permitting relative rotation between a seatback and a seat bottom and a locked state preventing relative rotation between the seatback and the seat bottom. The attachment plate is rotationally fixed to the recliner heart. The lever is rotatable between a first state in which the lever is engaged with the attachment plate and a second state in which the lever is disengaged from the attachment plate. When lever is in the first state and the recliner heart is in the unlocked state, rotation of the recliner heart causes corresponding rotation of the seatback relative to the seat bottom. However, the seatback is configured to rotate relative to the seat bottom without causing corresponding rotation of the recliner heart when the lever is in the second state.
