Abstract
The invention relates to a lock having a locking mechanism comprising a rotary latch and a pawl for locking the rotary latch in a locked position of the lock. An identification device for identifying a position of a moving component of the lock is provided. The identification device comprises a spring which is fitted to the component. The spring opens or closes an electrical circuit when the component and the spring which is connected to said component are moved. In this way, positions of the locking mechanism can be reliably determined, without having to worry about fatigue of the spring and associated problems.
Claims16
A latch comprising:
- a locking mechanism having a catch and a moving component that is movable between an unratcheted position and a ratcheted position for latching of the catch in a closed position of the latch,
- a detection device for detection of a position of the moving component of the latch, wherein the detection device includes a first spring attached to the moving component, and a second spring, and
- an electrical power circuit, wherein the first spring and the second spring are connected to the electrical power circuit, wherein the first spring is moveable with the moving component to disconnect and connect to the second spring by disengaging and engaging the second spring, respectively, to open and close the electrical power circuit, respectively, when the moving component is moved between the unratcheted position and the ratcheted position,
- wherein the first spring of the detection device, in a closed state of the electrical power circuit, abuts the second spring in a pre-tensioned state.
A latch comprising:
- a locking mechanism having a catch and a moving component that is movable between an unratcheted position and a ratcheted position for latching of the catch in a closed position of the latch,
- a detection device for detection of a position of the moving component of the latch, wherein the detection device includes a first spring attached to the moving component, and a second spring, wherein the first spring of the detection device is held by an axis of the moving component, and
- an electrical power circuit, wherein the first spring and the second spring are connected to the electrical power circuit, wherein the first spring is moveable with the moving component to disconnect and connect to the second spring by disengaging and engaging the second spring, respectively, to open and close the electrical power circuit, respectively, when the moving component is moved between the unratcheted position and the ratcheted position.
