A seat fore-and-aft adjuster for a vehicle seat may have a lower rail and an upper rail. The adjuster may also have a drive unit, a gearbox unit having a gearbox housing, and a cover element. The upper rail may have at least one through-hole. The cover element may have at least one covering region, which is formed from two cover legs opposite to and parallel with one another. The cover element may have at least one covering sub-region arranged laterally to the covering region. The covering sub-region is defined by a covering wing protruding vertically in the longitudinal direction from one of the cover legs. The covering region is frictionally and/or interlockingly connected to the housing section, and the covering sub-region covers at least one connecting region of the bracket above that of the upper rail by the covering wing.

A linear drive has at least one rack which is arranged along a longitudinal axis and has a plurality of teeth, a drive shaft arranged in a transverse axis transversely to the longitudinal axis, and at least two propulsion elements, each having at least one propulsion tooth. The at least two propulsion elements are linearly movable in a stroke axis which is oriented transversely to the longitudinal axis and transversely to the drive shaft. The at least two propulsion elements are drivingly coupled to the drive shaft in such a manner that the at least two propulsion elements perform at least one cyclical stroke movement in the course of one rotation of the drive shaft and enter and exit the at least one rack to generate a propulsion in the longitudinal axis. The at least two propulsion elements enter and exit the at least one rack with a phase shift.

Provided is an electric seat control apparatus for a vehicle including: a first rail and a second rail mounted at a constant interval on the floor surface of a vehicle body in the forward and rearward directions of a seat; a first movement unit provided with a first motor and mounted between the first rail and the lower surface of the seat to move linearly along the first rail; a second movement unit provided with a second motor and mounted between the second rail and the lower surface of the seat to move linearly along the second rail; and a control unit that simultaneously receives the RPM and a rotational position signal of the first motor and the RPM and a rotational position signal of the second motor to synchronize the RPMs and rotational positions of the first motor and the second motor to match each other.

A longitudinal adjusting device for a vehicle seat with a floor rail for fastening to a vehicle floor, the floor rail having a base wall for resting on the vehicle floor, with a seat rail that is displaceable with respect to the floor rail, with a spindle that is rigidly coupled to the floor rail, with a gear, which has a spindle nut, which is in engagement with the spindle, and is axially rigidly coupled to the seat rail, and with fastening means, which are guided through fastening openings on a fastening wall of the seat rail for fastening the gear on the seat rail. The longitudinal adjusting device may have a fastening wall arranged at an angle to the base wall and the fastening means for enclosing the gear reach through the complete seat rail and also absorb the crash forces with dual shear.

A slider for a vehicle seat, in particular for a motor vehicle seat, comprises a first profile section and a second profile section, the first profile section being movable in translation along a longitudinal direction of the seat, relative to the second profile section, the second profile section being intended to be fixed, under a floor of a vehicle passenger compartment; a slider actuator controlling the movement of the first profile section relative to the second profile section, the slider actuator comprising a motor intended to be arranged above the floor of the vehicle passenger compartment, and a reduction mechanism. The reduction mechanism comprises a belt, preferably notched, intended to pass through a slot in the floor of the vehicle passenger compartment.

Disclosed is an apparatus for moving a motor-operated seat rail, the apparatus including a lower rail coupled to a vehicle body and located on a lower surface of a floor, an upper rail configured to integrally move with a seat along the lower rail, a lead screw located inside the lower rail, a drive unit located in the upper rail, a gear box located in the lead screw, the gear box receiving driving force from the drive unit to integrally move with the upper rail along the lead screw, and a drive transmission unit located between the drive unit and the gear box.

In an arrangement which includes: a seat support body slidably supported on a fixed rail fixed to a floor; a power supply device supplying power to an electrical component on a seat side; and a drive device driving the seat support body in a front-and-rear direction and having a motor and a transmission member disposed so as to pass longitudinally through an interior of the fixed rail, the power supply device includes: a housing housing an electric wire for power supply; and a slider linked to the seat support body and slidable within the fixed rail. The electric wire is drawn out from the housing, retained by the slider and slidable within the fixed rail. The slider has an interference-avoiding portion for avoiding interference with the transmission member disposed so as to pass longitudinally through the interior of the fixed rail. Accordingly, the transmission member of the drive device and the slider for retaining the electric wire, which slides within the fixed rail, can be arranged in proximity to each other within the fixed rail while avoiding interference therebetween, thus enabling simplification and a reduction in the size of a rail structure.

A track system includes a track member with an elongate shaft mounted thereto. At least one support mechanism is mounted to the track member. The at least one support mechanism includes a housing. An engagement feature includes first and second engagement members spaced-apart from one another to define a receiving area therebetween. The first and second engagement members are operable between deployed and retracted positions relative to the housing. The elongate shaft is received in the receiving area when the first and second engagement members are in the deployed position.

A long rail assembly for use in an automotive vehicle includes a fixed long rail, a rail drive assembly having a drive wheel for transposing the rail drive assembly along the fixed long rail, an upper gearbox attached to a vehicle seat, and an auto-centering quick connection mechanism for operatively coupling a guide pin extending from the upper gearbox to the drive wheel when the vehicle seat is attached to the rail drive assembly. The auto-centering quick connection mechanism further automatically rotates the guide pin to a home position when the vehicle seat is decoupled from the rail drive assembly.

A vehicle seat support comprising two rails extending in a longitudinal direction, a central module slidably mounted on the rails and suitable for supporting the vehicle seat, a footrest slidably mounted on the rails in front of the central module and suitable for receiving the feet of an occupant seated on the seat, a first actuation system able to cause the central module to slide along the rails, and a second actuation system able to cause the footrest to slide along the rails independently of the central module.
