Abstract
A locking device (1) for a vehicle seat, particularly for a motor vehicle seat, has a housing (5), a catch (11) mounted in a movable manner on the housing (5) for locking with a mating element (B). At least one safety element (25, 31) is provided for securing the catch (11) in the locked state and can be moved relative to the catch (11) for unlocking the locking device (1). A query device (40) queries the locking state of the locking device (1) and has at least one transducer (41, 42) and at least one sensor (43). The query device (40) is designed in a contactless manner. The transducer (41, 42) and the sensor (43) interact with each other due to the relative positioning and/or movement thereof.
Claims17
A locking device for a vehicle seat, the locking device comprising:
- a housing;
- a pawl mounted in a movable manner on the housing for locking with a mating element;
- safety elements for securing the pawl in a locked state, and for moving relative to the pawl for unlocking the locking device, the safety elements including a clamping element exerting a closing moment on the pawl in a normal case, and a catch element supporting the pawl in the event of a crash;
- and
- a query device for querying the locked state of the locking device, the query device having a transducer and a sensor, the query device being contactless with the transducer and the sensor interacting with each other due to the relative positioning and/or movement thereof, wherein just one of the safety elements comprises the transducer and another one of the safety elements has a passive element, which interferes with the field of the transducer.
A vehicle seat comprising:
- a seat part;
- a backrest connected to the seat part;
- and
- a locking device comprising:
- a housing;
- a pawl mounted in a movable manner on the housing for locking with a mating element;
- safety elements for securing the pawl in a locked state, and for moving relative to the pawl for unlocking the locking device, the safety elements including a clamping element exerting a closing moment on the pawl in a normal case, and a catch element supporting the pawl in the event of a crash;
- a query device for querying the locked state of the locking device, the query device having a transducer and a sensor, the query device being contactless with the transducer and the sensor interacting with each other due to the relative positioning and/or movement thereof;
- and
- a backrest inclination query device for determining a backrest inclination, wherein in addition to the at least one transducer of the query device for determining the locked state, at least one transducer of the backrest inclination query device is also provided, the transducers cooperating with at least one sensor, wherein all transducers and sensors are integrated in the housing for determining said locked state and/or for determining the backrest inclination.
