An embodiment of the present disclosure provides a swing-in type of door structure of a vehicle that includes a door disposed in parallel at both sides of an entrance of a vehicle, and a door arm mounted on one side of the door to open or close the door by rotation, including: a center door bracket of which one end is fixed to one surface of an upper center of the door and that extends in a direction perpendicular to the door; a roller bracket of which one end is coupled to the other end of the center door bracket in a direction perpendicular to the center door bracket; and a roller mounted on the other end of the roller bracket and coupled to be rolled and rotated while in contact with a rail formed on a vehicle body of an upper side of the door.

An assembly for assisting in lifting a tailgate includes an elongated housing extending along a predetermined length, a spring anchored at one end at a first end of the housing, and a connector having a first end affixed to the opposite end of the spring and extending through the housing. In one embodiment, at least three rollers are provided for engaging the connector. The rollers may be arranged in a variety of configurations to maintain the connector and spring in a generally centered location within the housing. In another embodiment, at least two vertically aligned guides are provided. A vehicle for integrating the foregoing assemblies is also provided.

An opening and closing body drive device for a vehicle includes a belt frame, plural driven pulleys, a belt wounded around the plural driven pulleys and fixed with a connector with respect to an opening and closing body, a drive unit provided with an output shaft including a rotary axis which extends in a different direction from a rotary axis of each of the plural driven pulleys, and a drive pulley connected to the output shaft of the drive unit. The drive pulley includes a rotary axis extending in the different direction from the rotary axis of each of the plural driven pulleys while extending in the same direction as the rotary axis of the output shaft. The drive pulley is wound with the belt which is twisted between the driven pulleys arranged at opposing sides of the drive pulley in a circumferential direction of the belt.

A bracket (102) for mounting a pulley (42a) of a window regulator assembly (30) to a carrier 18a of a closure panel (14) of a vehicle (10), the bracket comprising: a body (106) having a first portion (108) and a second portion (110); a pulley aperture (100a) in the first portion, the pulley aperture having a pulley rotation axis (100b); a connection aperture (104a) in the second portion, the connection aperture having a connection axis, such that the connection axis and the pulley rotation axis are non-concentric; wherein a first fastener (100) is used connect the pulley to the pulley aperture and a second fastener (104) is used to connect the bracket to the carrier.

This invention provides sliding door enclosure assemblies for a framework structure, which uniquely enables equal lateral displacement of sliding doors, with the minimal engagement of a single door alone. More specifically, the sliding door enclosure assemblies of this invention comprise paired rotatable sliding doors, paired rotatable leaders, paired rotating conveyors, which conveyors are advanced by the paired rotatable leaders, guides which further comprise attachment regions to attach the paired rotatable sliding doors to the paired rotating conveyors and at least one interlocking rotatable movement regulator set of two elements, which rotate in equal and opposing directions, so that paired rotatable leaders operationally connected thereby promote lateral displacement of operationally connected rotatable sliding doors about the framework structure.

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.

A counterbalance assembly for an appliance has a guide member with a rotatable pulley with a fixed radius and a cam affixed to one side of the pulley and having a varying radius. The cam and the pulley rotate about a pulley axis of rotation as a single unit. The counterbalance has a force applicator that applies a counterbalance force to one of the pulley or cam, and the counterbalance has a connector that couples the other of the pulley or cam to the door. The counterbalance force applies a varying counterbalance torque to the door that is a function of the ratio between the fixed radius and the varying radius over the pivotal range of the door.

A door device for the interior of a passenger transport vehicle, and a passenger transport vehicle having at least one door device. The device includes a double-leaf sliding door with a first door leaf and a second door leaf in one plane. The door device has an upper guide for the first door leaf and an upper guide for the second door leaf. The guides are parallel with one another, and at least the upper guide for the first door leaf is offset with respect to the plane of the first and the second door leaf.

A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to a closing cable a part of which is wound around the rotating drum and that is hung on a closing inversion member and an opening cable a part of which is wound around the rotating drum and that is hung on an opening inversion member. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. An outer diameter of the rotating drum of the drive device is made smaller than a maximum diameter of a deceleration mechanism for making the rotating drum rotate forward and backward.

A door tensioning system for an oven or other appliance includes a chain and spring assembled as a pull member attached at one end to a door and at an opposite end to a base member of the appliance in a manner maintaining spring-mediated tension between the door and the base/bulk of the appliance. The pull member is routed around a bracket-assembly-mounted pulley, where the bracket assembly includes at least one movable bracket member that is movable with the pulley in a manner that will increase or decrease tension in the pull member by increasing/decreasing its effective length between its ends.
