Patent number: 9765552Abstract: A door handle assembly for a motor vehicle includes an operating handle moveably supported on a handle mounting, a mechanical coupling device and a locking device. An acceleration force can move the locking device from a normal operating position, in which an actuation of the operating handle is possible, in a first blocking direction, in which an actuation of the closing assembly via the operating handle and/or the coupling device, is blocked. The locking device also blocks the door handle assembly when long lasting or strongly pronounced oscillations occur as a result of a crash. In that event, the locking device can move from the normal operating position in a second blocking direction, in which an actuation of the closing assembly via the operating handle and/or the coupling device is blocked, wherein the second blocking direction is oriented opposite the first blocking direction.Type: GrantFiled: June 4, 2014Date of Patent: September 19, 2017Assignee: Huf Huelsbeck & Fuerst GmbH & Co.

Patent number: 8511726Abstract: The invention relates to an outside door grip, in particular for vehicles. The outside door grip exhibits a manually actuated handle, which engages a lock disposed in the door upon actuation. In addition, a pivotable blocking member serving as a mass blockage is furnished, which blocking member is disposed generally in its ineffective disengagement position, wherein the handle remains actuatable, which blocking member moves into an effective blocking position based on the inertia of its mass in case of a crash and thereby blocks the handle. Furthermore a damping device is furnished which takes care that the blocking member remains at least so long in its blocking position in case of a crash, until oscillations caused by the crash and acting on the outside door grip and/or the handle, have decayed so far that an effective actuation of the handle by the oscillations is not any longer possible.Type: GrantFiled: June 12, 2009Date of Patent: August 20, 2013Assignee: Huf Hülsbeck & Fürst GmbH & Co. KG.Inventors: Ralf Lennhoff, Sascha Pfeiffer
