One of the planetary gear mechanism and the drive unit is disposed outside the outer lower arm in the width direction. The other of the planetary gear mechanism and the drive unit is disposed outside the inner lower arm in the width direction.

Seat lifter

A seat lifter includes: an inner link for changing a height position of an inner lower arm with respect to a floor of a vehicle; an outer link for changing a height position of an outer lower area with respect to the floor; a coupling rod that couples the inner link to the outer link; a planetary gear mechanism capable of causing the coupling rod to rotate relative to the inner lower arm and the outer lower arm; a drive unit capable of driving the planetary gear mechanism; and a power transmission rod that transmits power of the drive unit to the planetary gear mechanism. The planetary gear mechanism is disposed between the inner lower arm and the outer lower arm. The drive unit is disposed outside the inner lower arm in the width direction or outside the outer lower arm in the width direction.

A vehicle seat includes: a base mounted to a floor of a vehicle; a seat cushion that is placed on the base and allowed to be tipped up with a rotating shaft as a fulcrum; an ottoman that is provided on a front side of the seat cushion and extractable between a normal position and an extracted position; a seat back that is provided in a rear end of the seat cushion; and a storage locking mechanism that is capable of relatively moving the ottoman with respect to the seat cushion in a storing direction which is a direction opposite to an extracting direction, wherein the storage locking mechanism is operated such that the seat back becomes in a forward-tiltable state and/or the seat cushion becomes in a tippable state, and locking of the locking mechanism is released so that the ottoman becomes movable in the storing direction.

Vehicle seat

A seat sliding device for a vehicle includes a sliding load adjusting mechanism. The sliding load adjusting mechanism includes a support member, which is fixed to a first rail that is one of a lower rail and an upper rail, and a pressing member, which is movably supported by the support member. The pressing member changes a frictional force that is generated between the pressing member and a second rail, which is the other one of the lower rail and the upper rail, in accordance with a pressing force applied to the second rail. The pressing force changes in accordance with the position of the pressing member in relation to the support member. As the upper rail moves in a first direction, the pressing member moves toward a side on which the pressing force is reduced.

Seat sliding device for vehicle

A vehicle seat sliding device for sliding a seat includes a fixed rail, a movable rail, a rolling element, and at least one rolling element holder. The fixed rail is for a floor of a vehicle. The movable rail is slidably engaged with the fixed rail and is mounted to the seat. The rolling element includes an outer circumferential surface for abutting an abutment surface of the fixed rail. The at least one rolling element holder is mounted to the movable rail and holds the rolling element so as to be rotatable and slidable along a longitudinal direction of the movable rail. The at least one rolling element holder is configured such that a distance between a rotation axis of the rolling element and the abutment surface becomes smaller as the rolling element slides toward one side in the longitudinal direction of the movable rail.

Vehicle seat sliding device

A seat sliding device that supports a seat so that the seat is slidable is provided. The seat sliding device includes a fixed rail having a first rail-surface and a second rail-surface, a movable rail that is configured to be slidable relative to the fixed rail, a roller that is mounted on the movable rail, a first rolling element that is formed into a sphere, and a first retainer that is mounted on the movable rail. The roller receives a downward load imposed on the movable rail and rolls to contact the first rail-surface. The first rolling element rolls to contact the second rail-surface. The first retainer presses the first rolling element against the second rail-surface while rotatably retaining the first rolling element.

Seat sliding device

A rolling element holder holds a rolling element rotatably and slidably. A biasing unit biases the rolling element holder toward a first surface of a fixed rail. A projection is provided on the rolling element holder, and faces a second surface opposite to the first surface. The rolling element holder is configured so that a distance in an up-down direction from a contact point between the rolling element and the first surface to an end portion of the projection on the second surface side becomes larger as the rolling element approaches an end on one side in a slidable range of the rolling element, and so that the projection is brought into contact with the second surface at least when the rolling element is at the end on the one side.

A fixed rail comprises a first rail-surface facing upward and a second rail-surface facing downward. A movable rail is configured to be slidable relative to the fixed rail and to support a seat. At least one first roller is mounted on the movable rail. The at least one first roller is configured to receive a downward load imposed on the movable rail and to roll on the first rail-surface. At least one second roller is mounted on the movable rail and is configured to roll on the second rail-surface. At least one pressing member is configured to elastically deform and to upwardly press the at least one second roller upwardly against the second rail-surface.

A seat sliding apparatus for a vehicle includes a lower rail, an upper rail supported to be movable relative to the lower rail, and a pressing member attached to one of the lower rail and the upper rail via a biasing member. The pressing member constantly presses the other of the lower rail and the upper rail by a biasing force of the biasing member. The lower rail and the upper rail extend in a first direction. The pressing member obliquely presses the other of the lower rail and the upper rail so that force components are generated in both the first direction and in a second direction orthogonal to the first direction.

A seat slide device is fixed to the floor of a vehicle and includes lower rails, each of which includes a front range and a rear range and extends forward and backward, and an upper rail supporting a movable seat and capable of moving over the lower rails. The seat slide device also includes a lock portion, a stopper, and a stopper-releasing operating portion. The lock portion selectively restricts movement of the upper rail on the lower rails at a plurality of positions. The lock portion is provided to the upper rail. The stopper stops movement of the upper rail before the upper rail advances from either one of the front range and the rear range, past this range, to the other range. The stopper-releasing operating portion enables movement of the upper rail when the upper rail has been stopped by the stopper.

Seat slide device

Provided is a slide door device for a vehicle seat slide apparatus including: a lower rail configured to be fixed to a vehicle floor; an upper rail configured to be fixed to a seat; a lock mechanism that selectively locks a movement of the upper rail at an arbitrary position of the upper rail with respect to the lower rail; a stopper mechanism that has a stopper portion provided in the lower rail and a stopper member movably provided in the upper rail; an operation member that allows the movement of the upper rail, which is locked at the predetermined position, in the one direction by inputting an operation force for releasing to the stopper member; and a guide portion that is formed on the stopper member, and guides the stopper member so as to release the engagement between the stopper member and the stopper portion.

Vehicle seat slide apparatus

A vehicle seat device is provided with a first lock mechanism which restricts a first movement of the seat, a second lock mechanism which restricts a second movement of the seat, and a drive source which removes the restrictions imposed by the first and second lock mechanisms. The drive source is provided with an output section which can be driven in two directions, that is, in the forward direction and the reverse direction, by the drive source. The drive of the output section in the forward direction from the neutral position thereof removes the restriction imposed by the first lock mechanism, and the drive of the output section in the reverse direction from the neutral position thereof removes the restriction imposed by the second lock mechanism.
