A sliding door roller fitting includes a tilting lever having a long and short arm angled thereto. The long arm has a freely rotatably mounted running roller which projects beyond the long arm to roll along a running rail. The short arm has an outwardly curved outer side facing away from the running roller. The tilting lever is held on a sliding door-side bearing body and is tiltable between two end positions about a tilting axis parallel to a running roller tangent. The bearing body has at least one planar bearing surface which extends horizontally in the setting-out direction in the mounting position of the bearing body. The short arm of the tilting lever bears by its curved outer side against the bearing surface and rolls thereon during tilting of the tilting lever. The bearing body has two driving stops between which the tilting lever is arranged.

Systems and methods include providing an aircraft with a fuselage having a sliding door system disposed on at least one side of the fuselage. The sliding door system includes a forward sliding door having an upper slide rail and a lower slide rail, a rearward sliding door having an upper slide rail and a lower slide rail, an upper rail coupled to each of the upper slide rail of the forward sliding door and the upper slide rail of the rearward sliding door, a lower rail coupled to each of the lower slide rail of the forward sliding door and the lower slide rail of the rearward sliding door, and a plurality of actuators coupled to each of the upper rail and the lower rail and configured to displace and retract the forward sliding door and the rearward sliding door linearly with respect to the fuselage.

A door roller includes a carriage member comprising a plurality of bores, and a plurality of roller assemblies connected to the carriage member, each roller assembly of the plurality of roller assemblies including a pivot bearing rotatably disposed within a bore of the plurality of bores and a pair of rollers coupled to the pivot bearing. Each wheel assembly is configured to pivot relative to the carriage member.

A roller assembly for a sliding vehicle door includes a bracket structure having a first and second inner horizontal guide roller arranged to interact with an inner vertical surface of the track member. The bracket structure further includes at least a first and second vertical guide roller arranged to interact with a first inner surface of the track member, a resiliently arranged rotatable member arranged to interact with a second inner surface of the track member and at least one outer horizontal guide roller arranged to interact with an outer vertical surface of the track member.

A track door system for an aircraft includes a door having a first side and a second side opposite the first side. A first roller track and a second roller track are aligned adjacent one another on the first side of the door. A third roller track and a fourth roller track are aligned adjacent one another on the second side of the door. A first motion driver is configured to move the door along the first roller track and the second roller track. A second motion driver is configured to move the door along the third roller track and the fourth roller track. A drive unit is operatively coupled to the first motion driver and the second motion driver to provide electromechanical power for cooperatively moving the door forward to an open position or aft to a closed position.

This disclosure relates to a motor vehicle with an arrangement configured to oppose movement of a vehicle door, and a corresponding method. An example motor vehicle includes a body, a door configured to slide relative to the body between an open position and a closed position, and a bracket connected to the door. The bracket includes a slot. Further, a locking arm is mounted to the body, and, when the door is in the closed position, the locking arm is configured to move such that the locking arm is received in the slot.

A vehicle door opening and closing apparatus includes: a vehicle door; a rail mounted on a vehicle body; and a roller unit mounted on the vehicle door, and configured to move along the rail, where the roller unit allows the vehicle door to open and close in either a sliding mode, in which the vehicle door slides along the rail, or a swing mode, in which the vehicle door swings in a predetermined position of the rail.

A slide door driving device includes a support plate that is an elongated plate member, two driven pulleys supported respectively by opposite ends of the support plate in a longitudinal direction of the support plate; a belt wound around the two driven pulleys; a connector by which the belt is connected to the slide door; and a driving portion supported by the support plate and configured to drive the belt.
