A latching apparatus may have a normal mode of operation in which a mechanical signal is employed to actuate a door pawl, and hence to release a door latch ratchet. An electrical actuator may be employed to send that mechanical signal, and operation of the actuator may be governed by an electronic control unit (ECU). The latch apparatus may also have a second, or emergency, mode of operation in which a second mechanical signal path is employed either to cause an augmented force to be employed to release the pawl, or to cause a sudden impulse to urge the pawl to release, the sudden impulse being driven by a release of energy from an energy storage device, in particular a mechanical energy storage device. The apparatus may include either an electrical or a mechanical door handle interrupt to prevent unwanted activation. The device may also include an auxiliary electrical back-up power source in the event of a main power source failure.

An automobile vehicle lock is released under normal operating conditions by an electric motor. Under degraded conditions, a mechanical release of the lock is enabled. This allows the motor providing electrical release of the lock to be simply dimensioned for release under normal operating conditions with no requirement to over-dimension the motor to ensure the lock will open under degraded operating conditions. Because release of the lock is mechanical under degraded operating conditions, enablement of the mechanical release is provided by a low-power standby motor. This allows a compact and inexpensive standby power source to be employed.

An outer door handle for vehicles has a stationary housing in the vehicle door. The handle has a handle arm and acts on a lock arranged within the door. A pivotable latching member serves as a mass latching mechanism and makes the handle actuatable in a release position. Because of its inertia in a crash situation, the latching member reaches an active support position and blocks the handle. The pivot bearing for the latching member is located on the stationary housing. The movable handle arm has a shoulder. A counter shoulder is provided on the latching member. The folding movement path of the shoulder on the handle arm is intersected by the pivot movement path of the counter shoulder. In a crash situation the shoulder comes to rest against the counter shoulder. In the release position, the shoulder passes the counter shoulder upon handle actuation.

A blocking apparatus is cooperable with the latch lever of a vehicle door latching mechanism to prevent the latch lever from moving during a crash event, which prevents the latching mechanism from allowing the vehicle door to open. The blocking apparatus includes a housing supporting a linearly movable plunger engagable with a cam surface on the latch lever and a blocking member pivotally mounted for movement between a normal position and a blocking position. The blocking member moves into the blocking position due to the imposition of crash forces on the blocking member during a crash event. A centering spring mechanism biases the blocking member into the normal position and can return the blocking member into the normal position to permit movement of the latch lever after the crash event has occurred. The plunger is biased into engagement with the latch lever so as to move with the cam surface.

The opening of vehicle doors often leads to collisions with stationary obstacles that are not visible to the occupants or with moving obstacles that approach the vehicle without being noticed. Thus to avoid collisions when vehicle doors are opened, the aim of the invention is to take any modifications to the environmental situation of the vehicle as a result of a movement of the vehicle and the detected objects into consideration. This allows a collision of the vehicle doors with the objects to be reliably avoided. To achieve this, in a first step the portable trajectory of a vehicle is determnined. In an additional step, the objects in the vicinity of the vehicle are detected and probable trajectories of said detected objects are determined. Respective probability ranges are then defined both for the vehicle and the pivoting zone of the vehicle doors and for the detected objects. The probability ranges of the pivoting zones of the vehicle doors are respectively compared with the individual probability ranges of the objects, in order to determine whether they overlap. If an overlap is identified, a response; signal that indicates the risk of a collision is generated.
