A vehicle includes a rail-mounted component and a restraint monitoring system. The rail-mounted component can include one or more restraints. The restraint monitoring system includes a restraint control module, an encoder-decoder module, and a rail-mounted component control module. The rail-mounted component control module can include a restraint deployment loop and a restraint diagnostic loop. The restraint deployment loop can include a deployment signal amplifier. The restraint diagnostic loop can include a diagnostic signal amplifier. In examples that include both the deployment signal amplifier and the diagnostic signal amplifier, the deployment signal amplifier and the diagnostic signal amplifier may be wired in parallel.

A power seat track assembly may include an elongated first rail, a second rail, a motor assembly, and a power-transfer assembly. The second rail may engage the first rail and may be movable along a length of the first rail. The motor assembly may be mounted to the second rail and may be operable to drive the second rail along the length of the first rail. The power-transfer assembly may include a first component mounted to the first rail and a second component mounted to the second rail. The first component may wirelessly transmit power to the second component. The second component may be electrically connected to the motor assembly to provide electrical current to the motor assembly.

A rail for a vehicle seat having first and second sliding rail members driven by a motorized drive mechanism. The rail further comprises a mechanical lock actuated by a relative movement between the motorized drive mechanism and the second rail member in the event of an accident.

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 gearbox for a vehicle seat adjustment mechanism in accordance with the principles of the present disclosure includes first and second portions. The first portion includes a first body defining a first longitudinal recess and a first peripheral recess in fluid communication with the first longitudinal recess. The first body includes a concave first curved surface. The second portion includes a second body defining a second longitudinal recess and a second peripheral recess in fluid communication with the second longitudinal recess. The second body includes a convex second curved surface. The second curved surface has an equal and opposite curvature compared to the first curved surface. In an assembled configuration, the first and second curved surfaces are in contact, the first longitudinal and second longitudinal recesses cooperate to define a longitudinal passage, and the first and second peripheral recesses communicate to define a peripheral receptacle.

A rail system includes a lower rail and an upper rail guided therein where the upper rail is adjustable in relation to the lower rail via a longitudinal adjustment device, the longitudinal adjustment device comprising a threaded spindle attached inside the lower rail and a spindle nut screwed onto the threaded spindle which is firmly affixed to the upper rail via a transmission housing so that the upper rail can be displaced in the longitudinal direction by motorised actuation of the longitudinal adjustment device, the threaded spindle being covered, at least in certain regions, in the lower rail by a deformable protective element which comprises longitudinal edges extending in the longitudinal direction.

A novel power slide with a motor directly connected to a lead screw includes a left slide and a right slide each including a top rail, a bottom rail, a power motor, a lead screw, a threaded assembly and a retainer ring. A first slot and a second slot are formed in two ends of the top rail, respectively. The power motor is fixed to a lower surface of the top rail through a motor bracket. The lead screw has an end connected to the power motor and another end rotatably fixed to the lower surface of the top rail. A bottom portion of the threaded assembly is fixedly connected to an upper surface of the bottom rail, and the lead screw horizontally penetrates through the threaded assembly and is in threaded fit with the threaded assembly. The retainer ring is located in the first slot, and a gap is formed between the retainer ring and the first slot.

A longitudinal adjuster for a vehicle seat may have a first rail and a second rail. The rails may mutually engage around each other to form an inner channel. A spindle nut may be supported by the second rail and a spindle, operationally connected to the spindle nut, may be arranged in the inner channel. In one end region of the first rail, a screw drive driven by a motor and interacting with the spindle may be arranged. The screw drive may be enclosed by a housing. The housing may have at least one cylindrical bearing portion for bearing a worm wheel connected to the spindle. The housing may also at least one step adjoining the cylindrical bearing portion. The step may be designed to support the worm wheel in the event of a crash. A vehicle seat having the longitudinal adjuster is also provided.

The present invention provides a powered rail apparatus for a vehicular seat. A stationary rail is mounted to a floor panel so as to be hidden, and a movable rail, which is to be assembled with a seat, is coupled to the stationary rail via a rack-and-pinion mechanism so as to be moved anteroposteriorly. A power cable, which is configured to supply the power required to move the movable rail anteroposteriorly, to a motor, is disposed in the stationary rail so as to be hidden and so as to be moved together with the movable rail such that the movable rail can be smoothly moved forwards and backwards. Since the stationary rail and the power cable are embedded in the floor panel, it is possible to realize planarization of the floor panel.

Disclosed is a seat rail pair (2) for adjustment of a vehicle seat (8), in particular of a motor vehicle seat, in an adjustment direction (x), comprising a guide rail (10) extending parallel to the adjustment direction (x) for fastening to a vehicle floor, and a fastening rail (21), which is adjustably guided on the guide rail (10) in the adjustment direction (x) for fastening the vehicle seat (8), wherein an energy absorber element (5) is provided in a path, which introduces the force acting on the vehicle seat (8) into the vehicle structure, which energy absorber element permits a movement of the vehicle seat in the adjustment direction (x) under plastic deformation when a predetermined value of the force is exceeded.
