A gearbox includes a first divided body and a second divided body, and a shaft projection is formed on and a through-hole is formed in divided surfaces of the first divided body and the second divided body. A second recess on the second divided body side includes a second arc portion formed concentrically with an axis center of a worm wheel, and an upper linear portion and a lower linear portion which extend linearly toward the first divided body side from both ends of the second arc portion. A first recess on the first divided body side includes a first linear portion which extends linearly in a direction orthogonal to an intersecting direction, and an upper arc portion and a lower arc portion which are formed continuous to both ends of the first linear portion.

A sliding device configured for a vehicle, includes a magnetic module configured to slide on a floor of the vehicle and be fixed to the floor by a magnetic force or unfixed from the floor depending on a change in magnetic circuit due to a rotation of a first magnetic body provided in the magnetic module; a plurality of catching portions formed on the floor, spaced from one another, and provided along a movement route of the magnetic module, and fastening portions provided on the magnetic module and configured to be pressed downward by a first elastic body, the fastening portions being configured to mechanically fasten the magnetic module to the floor by being lowered and caught by the catching portions when the fastening portions are matched with the catching portions while the magnetic module moves.

A seat rail assembly capable of stably holding a position of one or more vehicle seats relative to the vehicle floor. The seat rail assembly includes an upper rail on which the seat is provided and a lower rail which is mounted to the vehicle floor. The upper rail is slidably provided within the lower rail, and incorporates an engagement assembly with a dual wedge engagement assembly to ensure constant contact between the lower and upper rails. A gearbox configured to remove lash may be provided on the upper rail for moving the upper rail relative to the lower rail.

A vehicle seat device comprises: a seat disposed at a vehicle width direction inner side of a side door of a vehicle; a rotating mechanism that rotates the seat about a vertical axis relative to a vehicle body; a sideways movement mechanism that moves the seat in a vehicle width direction relative to the vehicle body between a normal region and an inner region; and a control device which, when causing the rotating mechanism to rotate the seat, causes the sideways movement mechanism to move the seat from the normal region to the inner region before the rotation.

A vehicle seat sliding device includes: a lower rail fixed to a vehicle floor; an upper rail slidably engaging with the lower rail and supports a vehicle seat upward; a nut member fixed to a first rail which configures one side of the lower rail and the upper rail; a screw rod screwed into the nut member; a drive unit rotating the screw rod; and a support supporting the screw rod on a second rail which configures the other side of the lower rail and the upper rail. The support includes a holding member that is provided with an insertion hole into which the screw rod is inserted and that is fixed to the second rail, and a holding nut that is provided with a through-hole into which the screw rod is inserted and that is screwed to a screwing portion provided on the screw rod or the holding member.

A seat state detection apparatus according to the present invention includes: a detecting unit configured to, in accordance with a moving operation in a front-rear direction by an operator on a seat of a vehicle, detect a moving status value representing a status of a moving mechanism that moves the seat in the front-rear direction; and a determining unit configured to determine that the moving mechanism is in a first state when the detected moving status value is more than a first threshold value, and determine that the moving mechanism is in a second state when the detected moving status value is less than a second threshold value set to a value lower than the first threshold value.

An embodiment rail device includes an upper rail, a first bearing support on the upper rail, a lower rail, a bearing connection end on the lower rail and inserted into the first bearing support, a vertically elongated bearing contact adjustment hole on the lower rail, an upper bearing rotatably connected to the bearing connection end and in close contact with a floor of the first bearing support, a lower plate including a fastening groove that receives a lower end of the lower rail, a bearing shaft mounting hole on a wall surface portion of the fastening groove and matched with the bearing contact adjustment hole, a second bearing support outside the fastening groove and having an opened upper portion, a lower bearing rotatably disposed within the second bearing support, and a bearing shaft fastened to the bearing shaft mounting hole and the bearing contact adjustment hole by a screw.

A vehicle seat console includes at least one vehicle-side guide element and at least one seat-side guide element arranged parallel to the vehicle-side guide element. A length-adjustment device, which is acted on by a drive device and which is designed to bring about a relative displacement between the vehicle-side guide element and the seat-side guide element, is designed such that the length-adjustment device is provided between the seat-side guide element and a force-limiting apparatus, which is in turn coupled to the vehicle-side guide element.

A vehicle seat including a seat that includes a seat cushion and a seat back; an inclination drive portion configured to incline the seat back; and a slide mechanism configured to enable the seat to slide in a vehicle front-rear direction, in which the slide mechanism includes: a slide rail supporting to be able to move in a sliding manner in the front-rear direction; a slide drive portion configured to enable the upper rail to slide with respect to the lower rail; and a mode switching switch configured to enable mode switching, in the normal mode, a slide amount used by the seat when the vehicle is driven is used, in the relaxing mode, a slide amount at a position rearward with respect to the rearmost end in the normal mode is used, and, when the relaxing mode is switched to the normal mode, in a case where the seat back is inclined, the seat back is raised to the normal mode, and then the seat is moved forward to the normal mode.
