A mechanism for use with multiple latches that are to be released by a single handle and by a single pull. A method for actuating multiple latches with a single handle and by a single pull. A release mechanism for use with multiple latches that are to be released by a single handle and by a single pull, including: a first member slidably received within a housing; a second member rotatably secured to the first member for movement about an axis within the housing and with respect to the first member; a first cable secured to the first member and slidably received within the housing; a second cable secured to the second member and slidably received within the housing; and a third cable secured to the second member and slidably received within the housing, wherein the second cable is shorter than the first cable.

A vehicle door lock is disposed in a vehicle door and includes a ratchet wheel rotatable between a locked position where it captures a lock catch disposed on a vehicle body and an unlocking position where it releases the lock catch to allow the vehicle door to be opened. The vehicle door lock further includes an ice-breaking mechanism disposed in the vehicle door, and the ice-breaking mechanism applies a torque to the ratchet wheel to cause the ratchet wheel to rotate in a direction to push the lock catch so as to open the vehicle door. The vehicle door lock can be opened by pushing the ratchet wheel with e ice-breaker mechanism when the vehicle door is frozen or deformed due to collision, the operation noise is low, the cost is low, and the paint surface of the vehicle door is protected.

The invention relates to a double-leaf vehicle door device comprising at least the following: two door leaves, each of which can be moved between an open position and a closed position in the form of a respective end position and into any intermediate position between the first open position and the first closed position, wherein a first movement of the first door leaf between the first open position and the first closed position is carried out without mechanically coupling the first door leaf to the second door leaf in contrast to a second movement of the second door leaf between the second open position and the second closed position, and a common locking device is provided which locks the first door leaf in the closed position when the first door leaf is located in the closed position and which locks the second door leaf in the closed position when the second door leaf is in the closed position. A pre-locking function is provided such that of the first door and the second door leaf, the door leaf which first reaches the closed position is held in the closed position at least until the other door leaf has also reached the closed position, and the locking device is additionally designed to only then lock or become capable of locking the first door leaf and the second door leaf.

A motor vehicle lock comprising a locking mechanism which essentially consists of a rotary latch and a pawl, further comprising a drive and a securing element. The drive acts on the securing element via a toothed rack element that is equipped with a blocking element. According to the invention, the blocking element is in the form of a tilting lever defining at least two end positions of the toothed rack element.

The invention concerns an aircraft door having a lever (3) for emergency opening from outside, disposed in a lever window. The lever (3) for emergency opening from outside includes: a main arm (7) having a first aerodynamic surface (9); a profiled cowling (8) with a second aerodynamic surface (10); a driving stop (18) capable of rotating the profiled cowling (8) from its concealing position to its separated position when the main arm (7) passes from its retracted position to its deployed position.

A single-door control circuit for a train includes a first circuit for controlling a single door when the train is in a sleep state, and a second circuit for controlling a door of the train when the train is in a wake-up activated state. When the train is in the sleep state, the second circuit is not electrified, the first circuit works, a door control unit is electrified by a storage battery power supply, and the single-door control is triggered by an electric unlocking switch or a single-door button; and when the train is in the wake-up activated state, the first circuit is cut off, the second circuit is electrified, and under a condition that a cab on a local side is activated and the train is at a zero velocity, the single-door control is only triggered by activating the single-door button in the cab.

A motor vehicle door lock which is equipped with a locking mechanism that consists essentially of a rotary latch and a pawl. Also, at least one actuating lever chain for opening the locking mechanism in an emergency is provided. In addition, a control element which blocks the actuating lever chain indirectly or directly in normal operation and releases it in the event of an emergency, is provided. The control element is equipped with an electric motor having an output element.
