摘要:
In a fuel-injection valve, an armature (7) having upper and lower guide surfaces (12, 13) is arranged within a valve housing (1). Via the upper guide surface (12), the armature (7) is guided in a guide borehole (15) of the valve housing (1) directly below the magnet winding (3) of the fuel-injection valve. In this way the losses of magnetic flux are very small.

In an injection valve for fuel-injection systems for internal combustion engines, the closure member opens in the direction towards the combustion chamber. It has an outer surface which widens towards the combustion chamber. Above the closure member, a swirl chamber is provided in the housing of the injection valve, fuel continuously rotating in said swirl chamber as a result of a continuously open return-flow connection to a valve outlet.

A seat for a motor vehicle, includes a backrest part and a seat part. The backrest part is configured to fold relative to the seat part from a normal position into a folded position and vice-versa. A lower seat structure is included and the seat is configured to move relative to the lower seat structure. At least one front first fastening, one rear second fastening and one diagonal fastening are provided to fasten the seat part to the lower seat structure. The seat is configured to adjust at least into an entry position and into a lowered position distinguishable from the normal position, and the second fastening is configured to release in the entry position. The diagonal fastening is configured to release in the lowered position.

An access- and starting/driving-authorization system for a motor vehicle, having a portable transponder and a control unit accomodated in the motor vehicle, in order to control the smart master-key system and the engine control unit. In inquiry/response dialogs, the transponder and the control unit enabling or blocking access to the motor vehicle, and the starting and driving of the motor vehicle, using sets of code information that are matched to each other. Starting and driving the motor vehicle after forcibly entering the motor vehicle and replacing the engine control unit, including a vehicle immobilizer and a transponder of the control units relevant for starting and driving, is prevented in that the enabling of the motor-vehicle to be started and driven, after a successful starting/driving-authorization inquiry/response dialog, is rendered dependent on a preceding, successful access-authorization inquiry/response dialog.

The invention relates to a circuit for controlling an electrically activated motor vehicle door lock or the like, with a lock latch (1) and a detent pawl (2) which keeps the lock latch (1) in the closed position and with an electric motorized auxiliary closing drive (4) which is turned on after the lock latch (1) has reached a preclosing position and then moves the lock latch (1) by motor into the main closing position, there being a switch (16) which recognizes the preclosing position, especially a lock latch switch which scans the position of the lock latch (1). The structure of the circuit is especially simple in that the negative pole (18) of the auxiliary closing drive (4) is always connected to ground or negative potential and the positive pole (19) is switched and is either at the positive potential of the vehicle voltage or at ground or is floated and that there is only one switch (16) and the switch (16) is between the ground and a switch terminal (20) and causes switching of the auxiliary closing drive (4). Here it is especially feasible if the auxiliary closing drive (4) shuts off automatically when the lock latch (1) reaches the closed position, especially when the overstroke position of the lock latch (1) which is somewhat on the other side of the closed position is reached, when therefore the positive pole (19) of the auxiliary closing drive (4) is then at ground or negative potential or is open. This applies especially when the criterion for shutting off the auxiliary closing drive (4), when the closed position is reached, especially when the overstroke position of the lock latch (1) which is somewhat on the other side of the closed position is reached, is the power consumption of the auxiliary closing drive (4).
摘要:
A device for blocking and for releasing an adjusting mechanism having at least two parts which are movable relative to each other is disclosed. The device comprises a blocker configured to be brought at least into a blocking position and a release position relative to the adjusting mechanism. The device further comprises an actuator for changing the position of the blocker between the blocking position and the release position.

A vehicle security arrangement includes at least one functional control unit, which provides a first code word; a theft protection control unit, which is coupled via a bus to the at least one functional control unit; and at least one input unit, which transmits to the theft protection control unit a second code word which the theft protection control unit forwards to the at least one function control unit. The theft protection control unit may initiate the provision of the first code word and the second code word. In the at least one functional control unit, a comparison of the first code word of the at least one functional control unit with the second code word takes place. In case of agreement between the first code word and the second code word, the at least one functional control unit enables itself.

The invention relates to a closure comprising a closing head (20) and a lock (10) which rest on the immobile or mobile part of a door, flap or such like. The closing head (20) has an undercut axial shoulder (26) which during coupling is engaged by a radially mobile blocking member (11) in the lock (10). The lock (10) further comprises a sensing member (12) and a restoring member (13) for the blocking member (11). To make the lock less prone to malfunctions the invention provides for the axially spring-loaded sensing member (12) to be used as a locking means for the radially spring-loaded blocking member (11). When the locking effect is actuated the blocking member (11) is held in a release position in relation to the closing head (20). When the closing head (20) is engaged the sensing member (12) carries out an axial movement which releases the lock so that the radial spring-loading can move the blocking member (11) into its blocked position. Actuation of the restoring member (13) results in a radial reverse movement of the blocking member (11), which activates the locking of the sensing member (12) and locks the blocking member (11) in its release position.
