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 door keeper, for keeping a door opening angle of a door within a predetermined angle, includes a hinge bracket attached to a support structure; a keeper plate having a bracket side end portion pivotally mounted to the hinge bracket, a door side end portion, and a keeper guide slot having a door side slot end portion disposed proximate to the door side end portion of the keeper plate, the keeper guide slot extending from the door side slot end portion to an opposite slot end portion disposed at a location between the bracket side end portion and the door side end portion of the keeper plate; and a keeper member movably disposed in the keeper guide slot and fixedly attached to a lower part of the door. An opening motion of the door stops when the door side slot end portion engages the keeper member.

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.

A door holder, includes a retainer housing (230), which can be connected either to a door or a door frame, and a door retainer rod, which penetrates the retainer housing (230) and which can be articulated to the other of the door and the door frame The door retainer rod has at least one braking surface, and at least one braking element (50) that can be displaced toward the at least one braking surface is arranged on the retainer housing (230), which the braking element can be brought in contact with the at least one braking surface of the door retainer rod at least in some sections and thus produces a primary braking force component against the displacement of the door retainer rod, wherein the door retainer rod has at least one guiding surface, which is inclined with respect to the braking surface. A door holder that provides high holding forces at least in some sections is created in that at least one guiding element (235a, 235b) is arranged on the retainer housing (230), which the guiding element can be brought in contact with the at least one guiding surface at least in some regions and produces a secondary braking force component against the displacement of the door retainer rod.

A stowable check strap assembly for a vehicle having a body and a removable door. The assembly includes a bracket configured to rotatably couple to the vehicle body, and a check strap rotatably coupled to the bracket and configured to be operably and removably coupled with a door detent coupled to the removable door. The bracket is rotatable between a deployed position where the check strap is positioned to extend outwardly from the vehicle body and engage the door detent, and a stowed position where the check strap is positioned to be and is rotated toward the vehicle body for stowage thereof.

A door check device for installation between a vehicle body and a vehicle door that swings in opposing opening and closing directions relative to the vehicle body is provided. The door check device comprises a housing assembly and an elongated link member. The housing assembly comprises a first mounting structure, and a plastic housing member containing a biasing structure, a first link member engaging structure and a second link member engaging structure therein. The plastic housing member has a first engagement structure. The first mounting structure includes a plastic cover that has a second engagement structure that is constructed and arranged to engage with the first engagement structure to form an area of contact therebetween. The plastic housing member and the plastic cover are secured by fusion of the materials to each other in the area of contact between the first and the second engagement structures.

The door check includes a retaining bar (20) which can be connected to one of the two door assembly parts, i.e. the door (8) or the door frame (6), and a retaining housing (13) which can be connected to the other door assembly part. In order to design a door check that allows a vehicle door to be reliably and safely blocked in an automated manner, a threaded bar (50) can be accommodated in an axially movable fashion in a cavity of the retaining bar (20).

A stopper for stopping rotation of a planar element with respect to a frame when the planar element is hinged to the frame, the stopper has a longitudinal axis and comprises: a locking bar having a toothed surface and received within an indentation, an operation handle for moving the locking bar out of the indentation, a locking spring having a locking tooth that is urged into the toothed surface, a releasing lever for releasing the locking tooth from the toothed surface, a retention spring for urging the locking bar into the indentation. A linear movement of the operation handle moves a portion of the locking bar out of the indentation, the locking bar abuts against the frame, and, the locking bar is fixed in its position by means of the locking tooth that is urged against the toothed surface.

The pop-up apparatus for a vehicle door, includes a door check to be fixed to a vehicle door, a check link having one end supported to be supported on a body so as to be turnable, the check link being configured to perform relative movement with respect to the door check between the one end and another end of the check link while being applied with a pushing force by the door check, a push arm, which is arranged on a side closer to the another end of the check link, and is configured to turn about a rotation axis to apply a force so as to cause the relative movement of the check link in a direction in which the vehicle door is opened, a posture arm configured to turn about the rotation axis, and urging means configured to apply an urging force, which enables integral turning of the push arm and the posture arm, to the push arm and the posture arm when the posture arm turns.
