A door arrester, in particular for a door of a motor vehicle, includes a door retainer rod () which can be mounted on either one of the door () or the body () so as to be pivotable and has a first side () with profiling () formed on the first side (); and a first braking element which can be arranged on the other of the door () or the body () and in sections bears against the first side () of the door retainer rod () under the effect of a preload, and which, with the profiling () of the first side (), defines at least one retaining position. The first braking element has a central boring, the door retainer rod () has an elongate through-hole (), a guide pin () passes through the central boring and the through-hole (), and the guide pin () permits an axial movement of the first braking element along the guide pin ().

Door arrester

A door holder, includes a retainer housing (), which can be connected either to a door or a door frame, and a door retainer rod, which penetrates the retainer housing () 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 () that can be displaced toward the at least one braking surface is arranged on the retainer housing (), 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 () is arranged on the retainer housing (), 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.

Door holder

A retainer housing, in particular for a door check (), includes a first housing part () with a cavity () for receiving a brake body () and a spring system () of a door check (). The first housing part () has a first end () and a second end (), and a closing piece () which is situated on one of the first end () and second end () of the housing part. The closing piece () has an upper face () and a lower face (). Multiple elevations () are arranged on the lower face () of the closing piece (), concentrically around a centre point of the lower face (). The elevations () have a stop face () for a spring system () of a door check ().

Retainer housing for a door check

The door check includes a retaining bar () which can be connected to one of the two door assembly parts, i.e. the door () or the door frame (), and a retaining housing () 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 () can be accommodated in an axially movable fashion in a cavity of the retaining bar ().

Door check and method for blocking a door check

A door check is provided comprising a housing () that can be fixed to a door or door frame and is provided with a first housing half () and a second housing half () which can be connected to each other, and a stay bar () that penetrates an opening () within the housing () and is pivotally mounted on the door frame or door, the housing () and the stay bar () not being fixed to/mounted on the same part. The first housing half () and the second housing half () respectively delimit only one section of the circumference of the opening (). In order to create a door check that allows reliable and secure retaining and can be produced at low cost, a braking member () which is biased in the direction of the stay bar () by means of a spring element () is disposed in at least one of the two housing halves ().

Door check

The invention relates to a support housing comprising a housing part for an active component of a door stay, the housing part having at a first end an opening for receiving the active component. The problem of developing a support housing which can be produced on an industrial scale easily and flexibly in line with changing requirements is solved by the invention in that the housing part comprises a cut-off extruded profile. The invention also relates to a door stay comprising a stay bar with a first side, a first active component, which co-operates with the first side of the stay bar, and a support housing with a first housing part, the first end of which is open, and with an opening for the first active component, the first housing part comprising a cut-off extruded profile.

Door stay with support housing

A locking device for locking a first part to a second part, including a shaft which connects the first part and the second part to one another in a pivotable manner. A rotational movement of the shaft entrains the first part in rotation, and the second part is rotatably mounted on the shaft. The first part is arranged on the shaft in an axially moveable fashion and can be engaged with the second part, and at least one damping element is assigned to the shaft and to the first part.

Locking device

A door arrester for a door of a motor vehicle includes a holder housing including a passage opening for a retaining bar, the holder housing including a first supporting housing part. The first supporting housing part includes injection-molded plastic and a fastening portion for fixing the holder housing onto a part of the motor vehicle. A swinging element and a spring element are provided. The swinging element is pivotable relative to the passage opening toward the retaining bar. The spring element acts upon the swinging element. The first housing part includes a bearing for receiving the swinging element.

A door arrester is provided which comprises a housing (), fastened on either the door or the door frame, a retaining rod (), extending through an opening () in the housing () and fastened on the respective other part of door and door frame so as to be pivoted, at least one brake member () pretensioned in the direction towards the retaining rod () and having a peripheral surface () that is received in the housing () so as to be axially displaceable, and at least two fastening bores () oriented at an angle to the locating plane of the housing (). An aim of the invention is to improve the generic door arrester so that it reliably and securely holds the door while being inexpensive to produce. For this purpose, one fastening bore () each is disposed on both sides of the principle planes which are perpendicular to the locating plane of the housing ().

A doorstop that includes a retainer piece disposed on one of a door and a door support, the retainer piece including a plastic housing with a main opening and a guide opening arranged perpendicular to the main opening and parallel to a pivot axis of the door. The doorstop also includes a door retaining rod articulated on the other of the door and the door support. The door retaining rod passes through the main opening of the retainer piece housing and includes a brake ramp and a catch depression on a side of the door retaining rod. The doorstop also includes a catch device configured to determine specific door opening positions. The catch device includes a brake body and a spring. The catch device connects the retainer piece and the door retaining rod to each other in a moveable manner. The brake body includes a hollow cylinder having a semi-spherical closed end and an open end and is slidingly disposed in the guide opening of the retainer piece. The open end accommodates the spring so that the closed end is pre-tensioned by the spring relative to the brake ramp and catch depression and is guided in the guide opening free of tilt.
