Patent number: 6428058Abstract: A motor-vehicle door latch has a latch element displaceable between a holding position bolt and a freeing position, and a pawl movable between a latched position retaining the latch element in the holding position and an unlatched position allowing the latch element to assume the freeing position. A release lever engageable with the pawl is movable between an actuated position displacing the pawl into the unlatched position and an unactuated position leaving the pawl in the latched position. A lock member has an abutment engageable in a locked position with the release lever for inhibiting movement of the release lever from the unactuated position into the actuated position and unengageable in an unlocked position with the release lever for permitting movement of the release lever from the unactuated position into the actuated position. An actuating lever coupled to the door handle is pivotal on actuation of a door unlocking member, e.g. an inside or outside handle.Type: GrantFiled: November 20, 2000Date of Patent: August 6, 2002Assignee: Kiekert AGInventor: Ludger Graute
