A commercial vehicle used for parcel delivery is installed with a control module. The control module communicates wirelessly with a transmitter to give control to the vehicle operator. The vehicle operator can access the vehicle's cargo compartment through the bulkhead door and/or the rear door solely by using the transmitter as opposed to manually actuating the door latch. A door actuator is added to the bulkhead door such that when the bulkhead door is wirelessly actuated the door opens without operator assistance, and the process of the door opening does not damage the vehicle. Additionally, the vehicle operator can initiate the control module to allow a push-button start and stop of the vehicle's ignition system. Such elements contribute to time savings and cost savings for parcel delivery operators.

A vehicle door support device includes a support member and a support member that hold a door at an open position. Each of these support members includes: a cylindrical accommodating portion; a cylindrical cover connected to the accommodating portion; a cylindrical movable member movable relative to the cover in an axial direction; a gear mechanism arranged in the accommodating portion; a spindle connected to a first connecting portion of the gear mechanism; a rotation mechanism that rotates the spindle by movement of the movable member relative to the cover; and a coil spring that biases the movable member so as to advance with respect to the cover. At least the support member includes a magnetoresistive mechanism that is arranged in the accommodating portion, is connected to the second connecting portion of the gear mechanism, and applies a load to the spindle via the gear mechanism.

A system for adjusting a vehicle door relative to a vehicle body including an adjusting device, a control device for controlling the adjusting device. The control device is configured to receive an operating command and control the adjusting device based on receiving the operating command, and a sensor device for detecting an object. The control device is configured to evaluate for the purpose of collision protection monitoring whether an operating command is received in a near area relative to the vehicle door via an operating device. For collision protection monitoring, the control device is configured to use a first recognition area in a first operating mode upon receiving an operating command via an operating device in the near area, and in a second operating mode to use a second recognition area different from the first recognition area when an operating command is not received in the near area.

A speed of an opening-closing action of a back door, for example, is changed from an acceleration area to a deceleration area by way of a constant-speed area, and an opening-closing action of the back door is configured to come to an end in the deceleration area. In the deceleration area, deceleration (a second deceleration in FIG. 3, a fourth deceleration in FIG. 4) of an opening-closing action of the back door at a point before the opening-closing action of the back door comes to the end is set to be smaller than another deceleration (a first deceleration in FIG. 3, a third deceleration in FIG. 4) of the opening-closing action of the back door at a deceleration start point of the opening-closing action of the back door.

The partition wall for commercial vehicles comprises at least one fixed plate (20) and a sliding door (10) able to slide with respect to said fixed wall (20), predisposed to separate the cockpit of the vehicle from the loading compartment. The sliding door (10) is provided, along the upper edge and along the bottom edge, with a plurality of sliding wheels (11, 12) predisposed to slide respectively on an upper guide (13) and on a lower guide (14) associated with the structure of the vehicle. The sliding wheels (11, 12) have a grooved profile predisposed to be coupled with a corresponding rail (19) of said guides (13, 14) having conjugated profile.

The present disclosure is directed generally to powered trailer systems and, more particularly, to powered trailer systems for opening and closing trailer doors at, e.g., a vehicle loading dock, and to vehicle and/or trailer power delivery and charging systems. A powered trailer door operating system can include a guide track having a lower guide track portion and an upper guide track portion; a drive support coupled to the upper guide track portion having a drive shaft positioned within a central cavity; and a carriage slidingly coupled to the drive support and operably coupled to the trailer door. The carriage can be operably engaged with the drive shaft through the slot such that rotation of the drive shaft causes the carriage to translate along the drive support, thereby moving the trailer door between the open and closed positions.

A counterbalance hinge assembly includes a cam and compression device that counterbalances a weight of a door or a ramp. The compression device biases against a rotation of the door or ramp. The downward movement of the door or ramp drives cam followers in angled slots or cam surfaces of the cam. The angled slots or cam surfaces include varying angles of incline to correspond to varying torque forces of the door or ramp during the opening or closing movement of the door or ramp.

A hinge includes: a vehicle body-side hinge member that includes a vehicle body attachment portion for attachment to a vehicle body; a back door-side hinge member that includes a door attachment portion for attachment to a back door and a coupling portion extending from the door attachment portion toward the vehicle body-side hinge member, the coupling portion including a reinforcing rib on both edges in a width direction intersecting an extension direction of the coupling portion; and a rotational support member that couples an end portion, at a side of the vehicle body-side hinge member, of the coupling portion together with the vehicle body-side hinge member, and that supports the vehicle body-side hinge member and the back door-side hinge member so as to allow relative rotation of the vehicle body-side hinge member and the back door-side hinge member.

A door stop system is presented for restricting range of motion of a multi-axial hinge having a main link and a secondary link pivotally connected between a first end member and a second end member. In one or more embodiments, the system is configured to be positioned and held within cutout opening of the hinge, between the main link and either the first end member or second end member to restrict the range of motion. In one or more embodiments, the system includes a first stop component, a second stop component configured to be positioned around the secondary link within the cutout opening and connected together by the one or more fasteners. A portion of at least one of the first stop component or second stop component limits the range of motion of the hinge.

An apparatus for a vehicle includes a door rail configured to be installed on a door panel of a door, a vehicle body rail configured to be coupled to a vehicle body so as to be opposite to the door rail, a vehicle body rail slider coupled to one surface of the vehicle body rail so as to be slidable in a front-rear direction along the vehicle body rail, a door rail slider coupled to the door rail so as to be slidable in the front-rear direction along the door rail, a pulley rotatable in conjunction with a movement of the vehicle body rail slider, a speed reducer directly connected to the pulley, and a second arm hingedly coupled to the speed reducer and configured to move the door rail slider.
