The invention relates to a hatch operating mechanism arranged to control opening and closing movements of a hatch (202; 302; 402) covering an opening in a vehicle. The mechanism comprises a first and a second arm (211, 221; 311, 321; 411, 421), which are rotatably attached to the vehicle at a first end and rotatably attached onto the hatch at a second end. A first and a second connecting element (214, 224; 314, 324; 414, 424) are arranged extending between and displaceable relative to a pair of spaced apart, parallel guide means (216, 226, 217, 227; 316, 317; 416, 417) fixed to the hatch (202; 302; 402), wherein the second ends of the first and second arms (211, 221; 311, 321; 411, 421) are rotatably attached to a respective first and second connecting element (214, 224; 314, 324; 414, 424). The first and second arms (211, 221; 311, 321; 411, 421) are simultaneously rotatable in opposite directions about their first ends over an arcuate path; and the connecting elements (214, 224; 314, 324; 414, 424) are arranged to execute a reciprocating movement along the guide means (216, 226; 217, 227) during the rotation of the first and second arms over the arcuate path.

A mechanism to enable opening and closing of a vehicle door comprising a swing arm assembly in use pivotally coupled between a vehicle structure and a slide support carriage. The slide support carriage being mounted to an elongate rail assembly attached to the vehicle door for movement there along. The mechanism further comprises a motion control surface attached to or integral with the door assembly and a follower assembly to regulate relative simultaneous pivotal motion of the swing arm according to the position and motion of the slide support carriage along the rail assembly.

Passenger seating comprises rows of seats with a door assembly at the end of each row for improving a seat occupant's privacy. The door assembly includes a door that slides into and out of a base in a primary mode of operation, and which supports a secondary mode of opening. The secondary mode may involve pivoting on hinges. A latch is provided to prevent the door from being opened routinely in the secondary mode. The door assembly is also capable of retracting with respect to the adjacent seat to improve access.

A vehicle door actuator assembly includes a base plate having a first portion and a second portion, a first gear disposed proximate the first portion of the base plate, a second gear disposed proximate the second portion of the base plate, a third gear connected to the base plate, and a linkage engaging the first, second, and third gears. The base plate of the vehicle door actuator assembly is rotatable between a first position and a second position. As the base plate rotates between the first and second positions, the vehicle door actuator assembly maintains an outer surface of the vehicle door substantially parallel to a longitudinal axis of the vehicle at all points along a travel path of the vehicle door.

The present invention is directed to a stepless sliding doors system, comprising: two sliding doors (10), at least one of them comprising: two vertical poles (30); means (50) for rotating each of the vertical poles (30); to each side of the vertical poles (30) is firmly connected a hand-connector (36); each of the hand-connectors (36) is pivotally connected to a rail-cart (18) having two rollers (42); each of the rail-carts (18) comprises a horizontal hinge (58) disposed between the rollers (42), and a vertical springy hinge (70), for applying pulling or pushing force of the rollers on a rail thereof, thereby allowing placing the sliding doors of the system in the same plane when in the closed state of the doors, and shifting the doors one along the other in the open state thereof, and additionally preventing the wheels to deviate from a rail in the case of slight deformations.

The invention relates to an actuator, comprising a spindle drive, a first gear which causes a translational displacement of a first connection unit connected to the spindle drive, and a second gear which engages with the first gear and which is rotationally coupled to a second connection unit, wherein the actuator is designed such that a relative rotation of the two gears with respect to each other causes an actuation of the spindle drive and a displacement of the spindle drive relative to the central axis of the second gear. Furthermore, the invention relates to devices for supporting a pivot member, such as a door, with respect to a parent assembly, such as a vehicle body.

A roller carriage arrangement for a door or a window of a building, wherein the window or the door has a fixed frame and a leaf which can be released from the fixed frame and which can be displaced relative to the fixed frame together with the roller carriage arrangement.

Doors on a vehicle may be controlled by a door positioning system that moves the doors freely and fluidly relative to the body of the vehicle. The doors may include front and rear doors on each side of the vehicle. The door positioning system may control the movement and positioning of each door using a door mechanism coupled between the door and the body of the vehicle. The door positioning system may determine a position or path of motion for each door based on sensor data and user input. The door positioning system may issue corresponding control signals to actuators in the door mechanism to position the door accordingly. For example, the front door may slide open at an angle to accommodate an angled tire. Front and rear doors may open in opposite directions to create a large, unobstructed space for passengers to enter and exit the vehicle.
