A redundant rail and carriage assembly is disclosed. The assembly may include a primary sub-assembly including a primary rail and a primary carriage. The assembly may include a secondary sub-assembly including a secondary rail and a secondary carriage, the secondary rail being different than the primary rail, the secondary carriage being different than the secondary carriage. The assembly may be configured to couple to an actuatable door configured to actuate between a stowed door position and a deployed door position via at least one intermediate door position using one of the primary sub-assembly or the secondary sub-assembly, the secondary sub-assembly being configured to actuate the actuatable door via the secondary rail and the secondary carriage if one of the primary rail or the primary carriage of the primary sub-assembly fails.

Disclosed are a low track assembly and a sliding door. The low track assembly includes a track with first slide grooves, and pulleys located in the track. The pulley includes a support, a roller assembly, and a hanging clamp, where the support moves in the first slide groove by using the roller assembly, a first accommodating groove and an accommodating site that is perpendicular to and runs through the first accommodating groove are provided on the support, a second accommodating groove is provided on the hanging clamp, and the hanging clamp is located in the accommodating site; a stop wall is provided at a first end of the accommodating site, a second slide groove is provided on the stop wall, and the second slide groove extends in a height direction of the track; a threaded hole that runs through the hanging clamp is further provided on the hanging clamp.

A device for operating opposite sliding doors of a vehicle includes a center rail mounted at a center inside a door and formed in a curved shape so that the door moves to the outside of a vehicle interior of the vehicle when the door is opened. A center roller is mounted on the vehicle body so as to correspond to the center rail. The center roller is configured to move the center rail by being coupled to the center rail when the door is opened or closed as a center bearing unit formed at one side of the center roller is seated on the center rail. The center roller has a center shaft formed at a position spaced apart from the center bearing unit such that the center shaft can rotate the center roller.

The present invention provides an aircraft passenger accommodation unit comprising a seat, a shell that allows a passenger egress between an aisle and the seat through an opening, and a door assembly comprising a door slidable with respect to the shell between a retracted position and an extended position, a slide track attached to the shell, a slide runner for sliding along the slide track, and a connection mechanism for selectively connecting the door to the slide runner, wherein the door has a first sliding mode in which the connection mechanism connects the door to the slide runner and wherein the slide runner slides along the slide track, and a second sliding mode in which the connection mechanism does not connect the door to the slide runner and wherein the door slides in relation to the slide track. The invention also provides a door arrangement and associated methods.

An assembly of an adjustment device of a motor vehicle includes a support plate, on which at least one guide rail is disposed. A driver is movably guided on the guide rail, for a functionalized windowpane, in particular an electrically switchable or controllable windowpane. A flexible component is provided for guiding a cable which is connected or can be connected to the functionalized windowpane, in particular for conducting a current and/or for controlling the functionalized windowpane. A window opener of a motor vehicle having the assembly is also provided.

A hold lock mechanism for a vehicle door, the hold lock mechanism including a grip assembly configured to be mounted on a vehicle body, the grip assembly including a pair of grip members configured to releasably grip a door component and a hook provided on at least one of grip members, and a release assembly mounted on the door component, the release assembly including a release member configured to releasably engage with the hook.

A movable panel system is provided which has a guide provided with at least one rail, at least one glass panel and a carriage device slidingly supporting the at least one glass panel on the at least one rail. The carriage device has a carriage body engaged to the at least one glass panel, and a wheel group having at least two wheels, configured to slidingly engage the at least one rail, and a support frame, the at least two wheels being hinged, rotationally free, to the support frame. The carriage body and the support frame are mutually engaged by a hinge that allows reciprocal rotation.

A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer, reinforcing fibers, and at least one tribological modifier. The tribological modifier, in one embodiment, can comprise a graft copolymer. The use of a graft copolymer has been found to unexpectedly and dramatically improve noise generation when tested against various substrates, especially glass substrates.

A sliding door system for a vehicle includes a sliding door including an upper edge and a lower edge; a lower roller coupled to the lower edge of the sliding door, the lower roller defining a groove; a lower guide coupled to the lower edge of the sliding door adjacent to the lower roller, the lower guide defining a groove; an upper roller coupled to the upper edge of the sliding door, the upper roller defining a groove; an upper guide coupled to the upper edge of the sliding door adjacent to the upper roller, the upper guide defining a groove; a lower rail affixed to a frame of the vehicle and disposed vertically below the lower edge of the sliding door, wherein the groove of the lower roller is engaged with the lower rail and wherein the groove of the lower guide partially surrounds the lower rail; and an upper rail affixed to a frame of the vehicle and disposed vertically above the upper edge of the sliding door, wherein the groove of the upper roller is engaged with the upper rail and wherein the groove of the upper guide partially surrounds the upper rail.
