LATCH FOR A VEHICLE
First Claim
1. A lock mechanism between a moving part of a vehicle, such as a door (40) or hinged lid on the vehicle, and a stationary part of a vehicle, namely, the vehicle body (50),which consists of a lock (30) on one part (40) of the vehicle and a closing part (51) on the other part (50) of the vehicle,where the lock (30) comprises a rotatably supported (11) catch (10) and a swiveling (21) latch (20) that is spring-tensioned (22) towards the catch (10),the catch has a recess (19) for the closing part (51), a step profile (15) in the peripheral direction with a prelocking stop notch (13), and a main stop notch (14) for a locking catch (23) on the latch (20), and can be moved among at least three rotational positions (10.1 to 10.3), namely,an open position (10.1) of the catch (10), in which the closing part (51) can be moved in or out (52) of the recess (19), the latch (20) is supported by its locking catch on an initial section (16) of the step profile (15) that is located before the main stop notch (14) and the prelocking stop notch (13), and the door (40) can move freely,a prelocking position (10.2), in which the closing part (51) is captively grasped by the recess (19), the locking catch (21) of the latch (20) engages the prelocking stop notch (13) in the step profile (15) from behind, and the door (40) is in a preclosing position,and a main lock-in position (10.3), in which the closing part (51) of the catch (10) has been carried farther along, the locking catch (51) of the latch (20) engages the main stop notch (14) of the step profile (15) from behind, and the door (40) has been brought into its final closed position, whereinthe prelocking stop notch (13) and the main stop notch (14) are located at different radial distances (47, 48) with respect to the axis of rotation (11) of the catch (10),a sensor (35) determines this radial distance (47, 48) in the prelocking position (10.2) and the main lock-in position (10.3) and signals a control unit, andthe control unit carries out a certain function in the vehicle in response to the signal from the sensor (35).

Abstract
The invention relates to a latch that comprises a lock and a closing part that engages with the latter. Said lock comprises a catch (10) and a clink and said catch (10) comprises a receiving element (19) for the closing part and has a stepped profile in the direction of the periphery, said stepped profile having a prestop (13) and a main stop (14) for a locking point on the clink. Said catch (10) 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 (13) and the main stop (14) are placed on the catch (10) at a radial distance (47, 48), that is different from each other, in relation to the rotational axis (11). 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.
