  • Publication number: 20180050616
    Abstract: A seat reclining apparatus includes a stopper which is movable between a forward-tilt restriction position to stop the seatback at an intermediate stop position in an unlock range, which is set in front of a lockable range in which a reclining mechanism of the seat reclining apparatus allows the angle of the seatback to be adjusted, and a restriction release position to allow the seatback to tilt forward beyond the intermediate stop position, and is situated at the forward-tilt restriction position when the seatback tilts toward the intermediate stop position from the lockable range. The seat reclining apparatus further includes a holding mechanism which keeps holding the stopper in the restriction release position until the seatback returns to the lockable range from a state where the seatback tilts forward beyond the intermediate stop position following a movement of the stopper from the forward-tilt restriction position to the restriction release position.

  • Publication number: 20170218677
    Abstract: An opening-and-closing body configured to open and close an opening moves across a first section in which the opening-and-closing body moves in the closing direction against its own weight and a second section in which the opening-and-closing body moves in the closing direction according to its own weight. The driver drives the opening-and-closing body in the closing direction continuously from the first section to the second section. The predictor predicts that the drive section of the opening-and-closing body will shift from the first section to the second section when the driver drives the opening-and-closing body in the closing direction toward the second section from the first section. The drive controller decreases the driving output of the driver for driving the opening-and-closing body in the closing direction according to the result of the prediction made by the predictor.
