A releasable hinge assembly includes a mounting bracket, a hinge bracket, and at least one spring biased locking mechanism. The mounting bracket having a first mounting plate and two pin tabs extending therefrom, at least one of the pin tabs defining a through hole therein. The hinge bracket having a second mounting plate and a knuckle extending therefrom. The knuckle defining at least one cutout that is being L-shaped. The at least one spring biased locking mechanism having a pawl arm and a pin. The at least one locking mechanism positioned within the a channel of the hinge bracket with the pawl arm positioned within and projecting from the at least one cutout. The pawl arm configured to move within the at least one cutout to push the pin beyond a second end of the knuckle and through a through hole defined in the pin tab of the mounting bracket.

A vehicle operation detection device includes a storage unit configured to store a trained model obtained by machine learning using training data in which an image captured in advance and a body part used for a gesture of a user are associated with each other, an entry determination unit configured to determine whether, based on a position of the body part in the image obtained by inputting a newly captured image into the trained model, the body part enters a recognition area set in an imaging area of a camera, and a gesture determination unit configured to calculate a displacement vector of the body part based on images captured at a time interval after it is determined that the body part enters the recognition area, and determine, in accordance with whether a direction of the displacement vector is a direction corresponding to the gesture, whether the gesture is made.

An upper rail is located along an upper edge of a boarding opening. A center rail extends from a side edge of the boarding opening in a direction away from the boarding opening. A lower rail is located along a lower edge of a sliding door. An upper hinge that is guided by the upper rail and a center hinge that is guided by the center rail slide with the sliding door. A lower hinge that is guided by the lower rail is located at each of front and rear side edges of the boarding opening, and does not slide. A lower edge lock mechanism fixes the lower edge of the sliding door to a vehicle body side structure.

A vehicle side structure includes: a vehicle body side structure including a boarding opening through which an occupant gets into and out of a vehicle; a sliding door configured to slide to open and close the boarding opening; an upper support structure; a middle support structure; a lower support structure; and a drive unit located in an upper portion of the vehicle body side structure and configured to drive the sliding door to open and close via at least a part of the upper support structure. The upper support structure, the middle support structure, and the lower support structure are configured to support the sliding door in upper, middle, and lower portions of the vehicle body side structure in a vertical direction of a vehicle such that the sliding door slides, respectively.

A closing device for a motor vehicle includes a locking mechanism having a rotary latch and at least one pawl, a trigger lever, with the locking mechanism being unlocked by the trigger lever, and a blocking component which is arranged on the closing device for blocking a movement of the trigger lever when a load acts on the motor vehicle from the outside. The blocking component can be guided in the closing device in a movable manner.

A structure can be used for connecting a door latch cable to a retractable outside door handle assembly for a vehicle. A mounting housing is inserted into a case of the retractable outside door handle assembly in a longitudinal direction of the vehicle and hanged by and mounted at the case in a height direction of the vehicle. A door latch cable is movably installed at the mounting housing.

A door control device stops a door such that the door does not come into contact with an obstacle existing in a rotation range of the door. The door control device includes: a distance calculation unit configured to calculate a distance from the door to the obstacle; a speed calculation unit configured to calculate an actual speed of the door; a braking force setting unit configured to set a braking condition indicating transition of a braking force applied to the door; a speed estimation unit configured to estimate transition of an estimated speed of the door from start of braking until the door stops; and a braking force correction unit configured, during braking, to correct a braking force such that the braking force is increased, or reduced, when a time gradient of the actual speed is gentler than, or steeper than, that of the estimated speed.

A vehicle door device includes: a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device; and an action position detection unit detecting an action position of the swing door. The braking control unit sets a strong opening prevention boundary on a closing direction side from a fully open position as a mechanical opening action limit of the swing door and applies a braking force to the swing door that opens on an opening direction side from the strong opening prevention boundary.

An adjustment assembly for use in a vehicle, including an adjustable part configured to move between an open position and a closed with respect to a vehicle body. The adjustable part may include an outer side and an inner side. At least a portion of the adjustable part may define an opening extending between the outer side and the inner side. The adjustment assembly may include an ultrasonic transmitter, disposed on either the adjustable part or the vehicle body and may be configured to emit a number of ultrasonic waves to an obstacle, and an ultrasonic receiver disposed on the inner side of the adjustable part and configured to receive the ultrasonic waves reflected from the obstacle through the opening.

An assistance apparatus for opening and closing a scissor door for a vehicle includes: a door hinge having one side installed at a vehicle body to be rotated vertically through a hinge shaft, and having a door mounted at an opposite side thereof; a gas lifter having a first side installed at the vehicle body, and having a second side installed at the door hinge to assist a rotational force of the door hinge or keep a posture thereof through compression and elongation; and an opening and closing assistance unit for providing the rotational force to the door hinge in interlocking with the pressing operation of a vehicle passenger.
