摘要： A vehicle seat adjustment device includes a first adjustment mechanism, a second adjustment mechanism, and a controller. The first adjustment mechanism is moved in a first direction upon driving of a first motor to adjust a position of a vehicle seat. The second adjustment mechanism is moved in both the first direction and a second direction orthogonal to the first direction upon driving of a second motor to adjust the position of the vehicle seat. The controller controls and drives the first motor and the second motor. A speed at which the second adjustment mechanism is moved in the first direction is lower than or equal to a speed at which the first adjustment mechanism is moved in the first direction. When the second motor needs to be driven, the controller drives the second motor while driving the first motor.

摘要： Provided is a vehicle seat apparatus including drive mechanism for moving configuring elements of a vehicle seat using a motor drive, in order to adjust a posture; control mechanism for controlling the operation of the drive mechanism; a rotation sensor which outputs pulse signals synchronized with a motor rotation; position detection mechanism for detecting a movement position of the configuring elements by counting pulse edges of the pulse signals according to the motor rotation direction; and reverse rotation detection mechanism for estimating that a reverse rotation has occurred in the motor rotation, in a situation where the pulse edges are continuously detected after the motor drive is stopped, if the rotation direction is unchanged, in a case where a motor rotation speed indicated by the pulse edges after the stop becomes faster than the motor rotation speed before the motor drive is stopped.

摘要： A controller in a vehicle seat system is configured to execute a first pivot control to cause the second seatback to pivot at a first pivoting speed, a second pivot control to cause the second seatback to pivot at a second pivoting speed that is greater than the first pivoting speed, and a first determination process to determine, during execution of a tilt control, whether the second seatback will interfere with the first seatback. If the controller determines, during execution of the tilt control, that the second seatback will interfere with the first seatback, then the controller causes the first seatback to pivot and executes the first pivot control in at least a part of a pivoting process of the second seatback.

摘要： A seat slide apparatus includes a lock device, which is switchable between locked and released states, and a control device, which controls the operation of the lock device. The control device includes a manipulation detection portion, a first control portion, which switches the lock device to the released state in response to the detection of the manipulation and switches the lock device to the locked state in response to the stoppage of the detection of the manipulation, a door opening-and-closing detection portion, which detects opening and closing of the vehicle door, and a second control portion. The second control portion determines whether a door open-time release condition under, which the movement of the vehicle seat should be permitted is satisfied when opening the vehicle door, and switches the lock device to the released state and maintains the released state if the door open-time release condition is satisfied.

摘要： A vehicle seat is capable of being shifted to a walk-in state without side support parts or a tilt part hindering the seat back from folding forward. A seat includes a seat cushion, a seat back, and a leg rest part. The seat is provided with side support parts at left and right sides of an occupant, and a tilt part that moves a front portion of the seat cushion upward and downward. The seat is further provided with a detecting part that detects a state of the seat back, and a control unit that causes at least one of the side support parts and the tilt part to transit from a deployed state to a housed state when the detecting part detects that a forward turn of the seat back is started.
