Door arrester for vehicle doors of motor vehicles

摘要

A door arrester for vehicle doors of motor vehicles, comprising a retaining part for fastening to a door or door pillar and a housing. A door retaining bar passes through a through-opening in the housing in a longitudinally displaceable manner. The door retaining bar is pivotably fastened to the door or door pillar and has a contact surface which comprises at least one first contact portion and at least one ramp-shaped second contact portion. At least one retaining body is pretensioned in the direction of the door retaining bar by a spring element and guided in the housing. The retaining body comprises at least two contact elements, wherein the contact elements have different coefficients of friction relative to the operative connection with the contact surface of the door retaining bar.
