Latch for a vehicle
First Claim
1. A lock mechanism between a moving part of a vehicle, the moving part being 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 rotatable supported (11) catch (10) and a swiveling (21) latch (20) that is spring-tensioned (22) towards the catch (10),the catch (10) has a recess (19) for the closing part (51), a periphery having a profile (15) 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 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 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 profile (15) from behind, and the door (40) has been brought into its final closed position, whereinthe catch (10) has a larger radial distance (46, 47), relative to the axis of rotation (11), at the prelocking stop notch (13) than the radial distance (47, 48) at the main stop notch (14), so that at the periphery of the catch (10) there is a step profile (15),wherein due to the difference (46, 47;
- 47, 48) in the radial distance, the latch (20) assumes three different swivel positions (20.1-20.3) in the three rotational positions (10.1-10.3) of the catch (10), namely, a resting position (20.1) in the open position (10.1) of the catch (10), an initial operating position (20.2) in the prelocking position (10.2), and an end operating position (20.3) in the main lock-in position of the catch (10),wherein the latch (20) directly engages a sensor (35) and is the only actuator of the sensor (35) so that in response to actuation the sensor determines the actual one of the three swivel positions (20.1-20.3) of the latch (20) and signals a control unit,wherein, based on the signals from the sensor, the control unit determines the actual rotational position (10.1-10.3) of the catch (10) and carries out a certain function in the vehicle.

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.

1. A lock mechanism between a moving part of a vehicle, the moving part being 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 rotatable supported (11) catch (10) and a swiveling (21) latch (20) that is spring-tensioned (22) towards the catch (10), the catch (10) has a recess (19) for the closing part (51), a periphery having a profile (15) 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 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 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 profile (15) from behind, and the door (40) has been brought into its final closed position, wherein the catch (10) has a larger radial distance (46, 47), relative to the axis of rotation (11), at the prelocking stop notch (13) than the radial distance (47, 48) at the main stop notch (14), so that at the periphery of the catch (10) there is a step profile (15), wherein due to the difference (46, 47; -
47, 48) in the radial distance, the latch (20) assumes three different swivel positions (20.1-20.3) in the three rotational positions (10.1-10.3) of the catch (10), namely, a resting position (20.1) in the open position (10.1) of the catch (10), an initial operating position (20.2) in the prelocking position (10.2), and an end operating position (20.3) in the main lock-in position of the catch (10),
wherein the latch (20) directly engages a sensor (35) and is the only actuator of the sensor (35) so that in response to actuation the sensor determines the actual one of the three swivel positions (20.1-20.3) of the latch (20) and signals a control unit, wherein, based on the signals from the sensor, the control unit determines the actual rotational position (10.1-10.3) of the catch (10) and carries out a certain function in the vehicle. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
