A seat adjustment mechanism for a vehicle seat may have a number of first rail pairs, each first rail pair having an upper rail and a lower rail. A height adjustment mechanism may be arranged between the number of first rail pairs and a seat part of the vehicle seat. The height adjustment mechanism may have a number of second rail pairs, each second rail pair may have an upper rail and a lower rail. The number of first rail pairs and the number of second rail pairs can be actuated simultaneously.

A vehicle seat, includes a guide describing a trajectory, said vehicle seat being movable on the guide along the trajectory so that the vehicle seat is moved away from a vehicle center, and a front side of the vehicle seat is rotated about a vertical axis of the vehicle seat toward the vehicle center.

A tracking base assembly for an aircraft seat includes base rails mounted to floor tracks in an aircraft cabin by floor track fittings in fixed positions, the base rails connected by a tracking member for providing longitudinal tracking while minimizing added height. The base rails include tracking slots extending longitudinally, and the tracking member includes tracking elements translatable forward and backward along the tracking slots, allowing an aircraft seat mounted to the tracking member to translate forward from a retracted configuration into an extended or berthing configuration (and backward to the retracted configuration). The tracking member includes a locking mechanism for locking the tracking member and seat in intermediate positions within the tracking slots. The tracking slots may be oriented slightly downward from the horizontal to allow for gravity-assisted tracking or to counteract the nose-up flight angles associated with cruising altitude, providing for easier seat tracking.

A vehicle seat console movably attaches a vehicle seat in a vehicle which has a vehicle body with a floor structure. The floor structure forms a vehicle interior floor on which the vehicle seat is movably arranged parallel to the vehicle longitudinal direction and parallel to the vehicle lateral direction via at least one first rail assembly running parallel to the vehicle longitudi-nal direction and at least one second rail assembly running parallel to the vehicle lateral direction. The vehicle interior floor has a step running in the vehicle lateral direction, the step dividing the vehicle interior floor in the vehicle longitudinal direction into a first floor region lying at a lower height and a second floor region lying at a higher height, and the vehicle interior floor is constricted by wheel housings, which penetrate into the floor from the respective exterior, behind the at least one vehicle seat. The second rail assembly ascends towards the vertical vehicle longitudinal central plane from the vehicle exterior running parallel to the vehicle longitudinal direction.

A gravity-assisted tracking base assembly for an aircraft seat includes base rails mounted to floor tracks in an aircraft cabin by floor track fittings in fixed positions, the base rails connected by a tracking member for providing longitudinal tracking while minimizing added height. The base rails include tracking slots extending longitudinally, and the tracking member includes tracking elements translatable forward and backward along the tracking slots, allowing an aircraft seat mounted to the tracking member to translate forward and backward relative to the base. The tracking member includes a locking mechanism for locking the tracking member and seat in intermediate positions within the tracking slots. The tracking slots may be oriented slightly downward from the horizontal to allow for gravity-assisted tracking or to counteract the nose-up flight angles associated with cruising altitude, providing for easier seat tracking.

A railess variable seatback type rear seat includes: a linear movement device configured to convert a rotation of a motor into a linear movement; a sliding movement device configured to convert the linear movement into a sliding movement in which a seat cushion is pushed forward or backward; and a reclining angle change device configured to convert the sliding movement into a reclining movement, and to fold a seatback, which is connected to the seat cushion, forward or to recline the seatback backward.

A vehicle in one embodiment includes a driver module which can include a driver seat and a driver control assembly both of which are movably coupled to a chassis of the vehicle to allow the driver module to move between a center position and at least one of a left position and a right position along a first row in the interior of the vehicle. In one embodiment, the driver control assembly includes a steering wheel, a brake pedal, and an accelerator pedal. In one embodiment, a driver can drive the vehicle in any one of these positions. In one embodiment, the vehicle further includes a first rear seat and a second rear seat coupled to the chassis in a second row in the interior of the vehicle. In one embodiment, passengers in the rear seats can extend their legs into the first row when the driver seat is in the center position. In one embodiment, the driver seat and the driver control assembly are movable laterally along a set of rails coupled to the chassis of the vehicle. Other embodiments are also described.
