A door check apparatus includes a base member configured to be attached to a vehicle door, a threaded rod rotatably held by the base member, a first tubular member including a distal end portion configured to be connected to a vehicle main body, and a base portion. The threaded rod is arranged inside the first tubular member. At least a part of the first tubular member threadedly engages with the threaded rod. The first tubular member performs a relative movement in an axial direction relative to the threaded rod such that the first tubular member causes the threaded rod to rotate. The door check apparatus includes a brake mechanism configured to restrict the threaded rod from rotating.

A door holding device and system is disclosed that holds a door in a partially open configuration. The door holding device includes a first arm assembly that attaches to a door, a second arm assembly that attaches to a door frame, a movable clamping mechanism that clamps the second arm assembly to the door frame, and a pivot device that allows the first arm assembly and the second arm assembly to pivot with respect to each other.

A door check for vehicle doors, e.g. car doors having a door strap for being mounted to the chassis and a retainer for being mounted to the door movably and supporting the door strap relative to the retainer and provides a particular precise control over the door movement if the retainer has a cylinder supporting a piston which is spring loaded against the door strap and if an actuator is configured to augment the pressure in the cylinder upon demand to thereby augment the friction between the piston and the door strap.

A window assembly including a master frame defining a master frame opening, a first window assembly secured within a first portion of the master frame opening, a screen member secured within a second portion of the master frame opening adjacent to the first window assembly, a second window assembly pivotably attached relative to the second portion of the master frame opening, and a window opening system that includes at least one extending arm pivotably attached to the second window assembly and extending through an opening in at least one of the screen member and a screen frame in which the screen member is secured, the extending arm(s) having at least one arm aperture, a flange extending from the master frame and comprising at least one flange aperture, and a locking member engageable with one of the arm apertures and one of the flange apertures.

Disclosed is an arresting system for arresting a swivel motion between two swivel-mounted elements, including a brake rod connected to the first element, an arresting device on the second element with a housing, through which the brake rod extends, in which case the arresting device has a drive and at least one brake-shoe element that can be moved via the drive relative to the brake rod. The brake-shoe element is inside the housing and engageable with the brake rod upon exertion of a braking force. Included are a sensor, and an electronic device controlling braking force exerted by the brake-shoe element on the brake rod depending on the signals from the sensor. The drive is an electric motor driving in rotation an actuation element that, to produce the relative motion between the brake-shoe element and the brake rod, has an actuation cam acting on the brake-shoe element.

A vehicle door check mechanism includes a bellows to act as a pneumatic retarder to prevent a high load from being transferred from the door check mechanism to a structural part of a door of the motor vehicle if that door is opened to a fully open position at high speed.

A door component has a controllable damper device that contains a magnetorheological fluid as a working fluid. Two connection units of the damper device can be moved relative to each other. One of the two connection units can be connected to a support structure, and the other connection unit can be connected to a pivotal door device in order to damp a movement of the door device between a closed position and an open position in a controlled manner. The magnetorheological damper device has a piston unit and a cylinder unit which surrounds the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit has a first piston rod, which extends through the first chamber, and a second piston rod, which extends through the second chamber.
