The invention relates to a latch that comprises a lock and a closing part that engages with the latter. Said lock comprises a catch () and a clink and said catch () comprises a receiving element () for the closing part and has a stepped profile in the direction of the periphery, said stepped profile having a prestop () and a main stop () for a locking point on the clink. Said catch () can be adjusted at least between three rotational positions which are an open position, a stop position and a main stop position. In order to prevent problems with the latch, the prestop () and the main stop () are placed on the catch () at a radial distance (), that is different from each other, in relation to the rotational axis (). A sensor determines the different radial distance that is obtained in the prestop position and the main stop position, and informs the control device. In accordance with the information provided to the sensor, the control device performs the functions defined by vehicle.

Latch for a vehicle

The invention relates to a latch that comprises a lock and a closing part (). Said lock comprises a catch (), a click () equipped with an adjusting arm () and a motorised opening aid (). Said catch () comprises a receiving element for the closing part () and at least one stop notch () for engaging the click (). The opening aid () is equipped with an eccentric () that is driven by a motor, whereby the eccentric curve interacts with a lateral adjusting surface of the adjusting arm () and ensures that the clink () is displaced in a motorised manner from its locked position in the stop notch () into an elevated position. In order to prevent problems in the latch, an end segment () of the eccentric () and/or the adjusting arm () of the clink () is elastic. When in the elevated position, the clink () is on a fixed stop (), performing an elastic deformation () when passing the eccentric end segment () on the adjusting arm () of the clink (), until an end-sided shoulder of the eccentric () catches behind a counter shoulder on the adjusting arm (). After catching, the eccentric shoulder is supported on the clink counter shoulder and prevents the eccentric () from reversing.

Latch for vehicles

In a lock fitted with a rotary latch (), a detent () is provided that can engage inside a preliminary catch and inside a main catch () of the rotary latch (). The rotary latch () receives a locking part and can be transferred either manually or by means of a motor between an open position, a preliminary catch position and a main catch position (). The motor-driven displacement ensues via a closing aid or an opening aid. In order to obtain a space-saving design, the invention provides that a locking lever () is eccentrically mounted on the rotary latch () and is held in a central position by an impulse spring whereby functioning as a closing aid. A stationary, rotationally mounted driving element () serves an opening aid, and an opening lever () is rotationally mounted on this driving element. This opening lever () is also held in a central position by an impulse spring. The locking lever () projects inside the preliminary catch position always in the path of rotation of the eccentric () and is entrained in one direction when the motor turns. In an analogous manner, the opening lever () projects into the main catch position () in the path of rotation of the eccentric () and is entrained in the opposite direction during rotation (). The entrained opening lever () pushes, via the driver (), the detent () from the rotary latch (), whereby the door is opened by a motor.

Lock for doors and lids on vehicles

A locking device for a movable carbody part has a lock and an interacting locking member. The lock has a rotary latch with pre-catch, main catch, and recess. When closing the carbody part, the locking member moves into the recess and rotates the rotary latch into a pre-catch position in which a pawl drops into the pre-catch. A motor-driven closing aid has a working lever and a control lever that are pivotably supported within the lock and have crossing slider block guides. The same slider block is guided in both slider block guides. When the working lever is pivoted by the motor of the closing aid, a shoulder of the slider block hits a counter shoulder of the rotary latch and rotates the rotary latch from the pre-catch position into a main catch position in which the pawl is supported on the main catch of the rotary latch.
