The present application provides a roller bearing system comprising one or more bearings having a plurality of substantially hemispherical members. Each member includes an interior. A sleeve is disposed within each hemispherical member interior and configured to accept a shaft that passes through each hemispherical member, such that the hemispherical member turns about the shaft. Each also includes at least one stem coupled to the shaft. The stem is configured to provide a point of attachment to a particular bearing.

The present invention is a combination of a curtain clip and a curtain slide. The curtain clip includes a socket portion connected to a tab portion. The socket portion has a socket for receiving the ring of the curtain slide when the socket and ring are urged together. Resilient fingers in the clip socket define a slot for receiving the ring shank of the ring of the curtain slide. The body of the curtain clip has a tab portion for fastening to a curtain, either by sewing the tab to curtain, or inserting the tab portion in a pocket in the curtain.

A curtain system is described which includes a curtain having a plurality of rod engaging members attached thereto, a plurality of rods each having a first end, and a curtain release mechanism attached to each rod at the first end thereof. The rod engaging members each include a stem having a first end and a second end, the first end of the stem configured for engagement with the curtain release mechanism, and a keyway formed in the stem and proximate the first end of the stem.

A drapery system including a fabric-support car to operate within a track of the drapery system to operate a drapery fabric between a fully-extended position and a fully-retracted position. The fabric-support car includes a pair of wheels. a lower portion with a cavity to receive a connector to connect the drapery fabric to the fabric-support car. The fabric-support car includes a pair of guides disposed on opposed sides of a recess. Each of the guides includes a pair of arms that define a channel. The channel is configured to receive a cord. The fabric-support car includes a plurality of walls that partially surround the pair of wheels. The plurality of walls prevent the cord from entangling with the pair of wheels.

A drive assembly for moving a curtain of a vehicle includes a drive rack, an idle gear engaged with the drive rack, a motor assembly and an actuator. The motor assembly includes a drive gear engageable with the idle gear, a gearbox connected to the drive gear, and a motor connected to the gearbox for driving the drive gear. The actuator is for moving the motor assembly between an idle position, wherein the idle gear is idle, and a drive position, wherein the drive gear is engaged with the idle gear for driving the idle gear. When the motor assembly is in the drive position, the idle gear is drivable by the motor to move the idle gear along the drive rack. One of the drive rack and the idle gear is mountable on the curtain so as to move the curtain between a first and a second position.

A curtain support assembly is provided. The curtain support assembly includes a first rail, a second rail, and a connector. The first and second rails each include slide surfaces for supporting a curtain carrier moving along a curtain travel path. The connector includes a first end connected to the first rail and a second end connected to the second rail such that the first and second rails are separated from each other by a gap having a predefined distance. The connector further includes a ramp having a length greater than the predefined distance. The connector is configured such that a curtain carrier moving along the curtain travel path from the first rail to the second rail is supported by the ramp.
