A vehicle seat adjustment device mounted on a vehicle in which a plurality of seats including a last-row seat in a last row and a second-to-last-row seat in a second-to-last row is arranged in a front and rear direction and configured to adjust states of the last-row seat and the second-to-last-row seat. When respectively shifting the last-row seat and the second-to-last-row seat to their accommodation states by operating an operation part, the first drive part and the second drive part are controlled so that there is a period during which a seat back of the last-row seat and a seat back of the second-to-last-row seat are simultaneously rotated forward.

A seat adjuster for a vehicle seat is provided. The seat adjuster comprises a rotation mechanism that comprises a rotation part, a rotation drive device that rotates the rotation part, an engagement target member that is configured to be rotated integrally with the rotation part and comprises engagement target portions formed along a rotational direction of the engagement target member, and an engagement member that is configured so that, when one of the engagement target portions is located in a specified engageable position, the engagement member is moved in a direction closer to the engagement target member to be engageable with the one of the engagement target portions located in the specified engageable position.

A seat adjuster in one aspect of the present disclosure comprises a rotating part, a rotational drive, an engagement target member, an engagement member, and a controller. The controller executes a lock transition process in a case where a seatback is pivotally moved to a specified front-tilt position, which is further to a forward direction than an upright position is, while the engagement member is in an unlocked state where the engagement member is not engaged with any one of engagement target portions of the engagement target member. The lock transition process is a process where the controller rotates the rotating part via the rotational drive such that one of the engagement target portions is placed at an engageable position, and engages the engagement member with the one of the engagement target portions.

A control mechanism for a lock pawl comprises an electric motor mounted in a housing that is connected with the seat backrest and has an output shaft with a worm gear engaging with the spur gearing of a transmission gear rotary-mounted on a transmission pivot and having on its frontal surface an eccentric selector pivot for controlling the pawl of the lock, swing-mounted on a pawl pivot between a blocking position, in which the pawl blocks a rotary ratchet of the lock from releasing a catch eye connected with the car bodywork, and an unlocking position, in which the pawl releases the rotary ratchet to release the catch eye, the pawl having a radial selector arm, which in the blocking position of the pawl interferes with the circular trajectory of the selector pivot to enable the selector pivot to engage with the selector arm, whereas the pawl has a radial control arm.

A vehicle seat having at least one buckle for receiving a safety belt on a first lateral side of the seat and an attachment of the end of a pelvic strap of the safety belt on a second lateral side of the seat. The seat includes at least one safety device, each safety device having a first cable connecting the buckle or the attachment of the end of the pelvic strap to a first anchor point, and at least one second cable connecting the buckle or the attachment of the end of the pelvic strap to a second anchor point traction on the second cable resulting in a general movement of the buckle or attachment of the pelvic strap end eliminating the risk of submarining.

Proposed is a support driver for a seat and a support assembly including the same. The support driver is configured to operate within a limited space while supporting an occupant comfortably and safely. The support assembly has a structure in which the links push the central portion of the cushion in close contact therewith while remaining in intersection with each other. Advantageously, the links are able to push the cushion with a minimum amount of power within a limited space.

A seatback drive assembly includes a lower bracket, a seatback pivotally mounted to the lower bracket, and a lock cam pivotally mounted to the seatback. The lock cam holds the seatback in an upright position when the lock cam engages the lower bracket. A biasing spring moves the seatback to a folded position when the lock cam is disengaged from the lower bracket. The seatback drive assembly also includes a gear pivotally mounted to the lower bracket and having a set of gear teeth. A motorized pinion engages the gear and is driven by an electric motor.
