Abstract: In a vehicle seat, a second parallel link mechanism is actuated in order to adjust an vertical position of a seat body with respect to a vehicle body, such that a first parallel link mechanism is moved up or down together with the seat body with respect to the vehicle body. In order to recline a seatback as an integral unit with a seat cushion, the first parallel link mechanism and the second parallel link mechanism are actuated such that an upper link is maintained in a predetermined orientation. The upper link is restricted from rotating relative to the armrest, and so the armrest is also maintained in a predetermined orientation.

Abstract: A headrest includes: a main frame, left and right side frames, and left and right rotation-coupling portions. The main frame is supported at an upper end portion of a seatback. The left and right side frames that are disposed on left and right sides of the main frame. The left and right rotation-coupling portions couple the left and right side frames to the main frame such that the left and right side frames are capable of rotating with respect to the main frame about left and right up-down-extending axes. Each rotation-coupling portion includes a boss hole, a boss, a hinge hole, and a hinge.

Abstract: In a power seat operation device, a micro switch is attached inside a dial that is rotatably provided to a side face of a power seat. An opening is formed inside the dial, with an operation portion of a knob to operate the micro switch inserted through the opening. There is accordingly a possibility that liquid might infiltrate into the dial, however a channel is formed inside the dial by the dial and the knob. The channel lets liquid flow downward to the lower side of the micro switch so as to discharge the liquid to outside the dial in cases in which liquid has infiltrated into the dial through the opening in a state in which the opening is positioned at the upper side of the micro switch. The channel is partitioned from the micro switch, enabling flow of liquid to the micro switch to be prevented or suppressed.

Abstract: In a power seat operation device, a slider that is supported so as to be slidable in a radial direction with respect to a dial slides toward the radial direction center of the dial during rotation of the dial. A knob engagement portion that is provided to the slider is thereby disposed between a pair of slider engagement portions that are provided to a knob. This enables rotational operation of the knob to be restricted. However, during rotational operation of the knob, one out of the pair of slider engagement portions opposes the knob engagement portion from toward the radial direction center of the dial. This enables rotational operation of the dial in conjunction with sliding of the slider to be restricted.

Abstract: A vehicle seat that includes: a cushion frame rear portion that is rotatable around a rear portion shaft, whose axial direction is a seat transverse direction, with respect to a vehicle body floor portion; a cushion frame front portion that is connected to the cushion frame rear portion so as to be rotatable around a center fold shaft whose axial direction is the seat transverse direction and that is positioned further toward a seat front side than the rear portion shaft; a seatback frame that stands erect from a rear end side of the cushion frame rear portion; and a driving mechanism that moves the cushion frame front portion and the cushion frame rear portion relatively in a seat vertical direction between a non-reclining state and a reclining state, in which the cushion frame rear portion tilts downward and rearward with respect to the cushion frame front portion.
