An actuator and a vehicle operation system with the actuator. The actuator includes a housing unit composed of a combination of internal components including a motor, a housing and a cover. A pair of terminals conveys external power to the motor. A terminal holder holds die pair of terminals. The terminal holder is accommodated in the housing unit as a sub-assembly separately from the housing unit.

A multidirectional control apparatus for a vehicular seat is provided to perform anteroposterior tilting, lateral tilting, control of height and tilting in other directions in consideration of the body size of a passenger and the traveling environment. The multidirectional control apparatus improves passenger comfort by tilting the seat in a lateral direction when entering or exiting a vehicle, prevents the passenger from leaning to one side by tilting the seat in a lateral direction during turning of the vehicle, and offers a safety function of protecting the passenger by inclining the seat in the direction of a collision in the event of a collision of the vehicle.

A lower leg support device for a vehicle seat, with a bracket and with a lower leg support displaceably arranged on the bracket, which can be moved between a non-use position and a use position upstream in longitudinal extension, wherein the lower leg support has at least two support parts which are moveable relative to each other to increase or reduce a lower leg support surface of the lower leg support. It is provided that the support parts can be moved transversely to the longitudinal extension to each other in order to increase or reduce the width of the lower leg support surface.

Various vehicle seat improvements are enabled herein. For instance, a kinematic seat for a vehicle comprises a seat base connected to the vehicle. A first side member is affixed to a base at a first side of the base. A second side member is affixed to the base at a second side of the base, opposite the first side of the base. A slider is slidably received in the base. A seat back assembly is rotatably coupled to the first side member and rotatably coupled to the second side member. A linkage is rotatably coupled to the seat back assembly and rotatably coupled to the slider, whereby sliding of the slider rotates the seat back assembly. A first lower seat lifting mechanism comprises a lifting bracket, wherein the lifting bracket is rotatably coupled to the first side member at a first end of the lifting bracket, and wherein the lifting bracket is slidably received in a channel of the first side member at a second end of the lifting bracket. A second lower seat lifting mechanism comprises a bracket rotatably coupled to the base and a link arm rotatably coupled to the bracket and rotatably coupled to the slider.

A vehicle seat comprising a base, a seating portion connected to the base by a front connecting rod, a backrest support lockable on the base, a backrest pivotally mounted on the backrest support by a hinge mechanism and connected to the seating portion by a pivot. The backrest support is connected to the base by two rear connecting rods configured so that the backrest is folded horizontally in a console position when the front connecting rod pivots forward after unlocking the backrest support while the hinge mechanism is not actuated.

The invention relates to a motor vehicle seat with a seat inclination adjustment device, with a first base element, a first seat frame element and a first actuator element, wherein the actuator element has a lower link arm connected to the base element via a lower link and movably arranged relative to the base element, an upper link arm connected to the lower link arm via a middle link and movably arranged relative to the lower link arm, wherein the upper link arm is connected to the seat frame element via an upper link and is arranged movably, and an inclination adjustment fitting with a first and a second fitting part, and wherein the inclination adjustment fitting is arranged on one of the links.

A seat assembly includes a base frame supporting a lift mechanism. A seatback is operably coupled to a seat portion. The seatback and the seat portion are vertically adjustable as powered by the lift mechanism. The seat portion is pivotally coupled to the seatback by a support bracket for rotational movement between first and second positions. A seat frame of the seat portion is vertically juxtaposed over the lift mechanism when the seat portion is in the second position.

A seat assembly includes a mounting plate and a base frame rotatable mounted on the mounting plate by a swivel mechanism for swiveling the seat assembly between forward-facing and rearward-facing configurations. A seat portion is operably coupled to the base frame and includes a front edge. The seat portion can be pivoted between use and upright non-use positions. The seat assembly includes a first rotational footprint when the seat portion is in the use position and a second rotational footprint that is less than the first rotational footprint when the seat portion is in the upright non-use position. The second rotational footprint is intended to accommodate swiveling of the seat assembly between the forward-facing and rearward-facing configurations within a vehicle interior.

A seat longitudinal adjustment mechanism may have two pairs of seat rails which are each formed from a lower seat rail and an upper seat rail, which is movable in a longitudinal direction relative to the lower seat rail. An electric motor may be provided for driving the seat longitudinal adjustment mechanism. The electric motor may be arranged between the two pairs of seat rails. The electric motor may have a single output which may be coupled to one of the two movable upper seat rails. Further, a seat arrangement having a plurality of seats where a seat may have a seat longitudinal adjustment mechanism is provided.

An embodiment is a seat height gear system including a monopost apparatus configured to be mounted under a seat, the monopost apparatus comprising a lower post and an upper post, and a direct drive motor apparatus within the monopost apparatus, the direct drive motor apparatus including a motor and a gear unit, the gear unit including a pinion and a rack bar, the rack bar being configured to be engaged with the pinion, the motor being fixed to the lower post of the monopost apparatus, the pinion being coupled to the motor, the rack bar being fixed to an upper post of the monopost apparatus, the motor being configured to rotate the pinion, and the rack bar being configured to convert the rotation of the pinion into the linear motion.
