3) is released.

When the pushbutton switch is actuated, the front door (27), rear door (28) or trunk 1 (29) may open automatically due to the reaction force generated by the door seal. At the final stage of the movement of the rod (13),
The tension spring (15) returns the unlocking lever (9) to its rest position, as shown in FIG. 1, in which the pin (4) is not actuated. For this reason, the door (27) (2
8) or the trunk lid (29) can be closed again.

If all the occupants are in the passenger compartment of the car (26),
The doors (27) and (28) can be prevented from opening by avoiding activation of the switch (34') provided on the dash board. When the switch (34' is activated, the input terminal (37) of the block (37) 38), and a signal (51) is sent to the block (52). If it is detected that all switches (23) to (23'') are on (door (27) ( 28) are both closed), blocks (41) to (44) are closed.

On the other hand, if any one of the doors (27) (28) is open, the corresponding microswitch (23) (23
'(23'') or (23'') is off,
From block (52) a signal is fed to block (40) rather than block (54). and block (4
0) determines whether blocks (41) to (44) are allowed to operate. Block (68) for closing fl (72) is not activated. The interrogation status of at least one of the doors (27028) is indicated by the lighting of a lamp (55) to which a signal from the block (52) is sent. The operating state of the blocks (41) to (44) for controlling the opening of the doors (27) and (28) is indicated by a lamp (56). The lamp (56) further determines whether or not the blocks (41) to (44) are permitted to operate based on a signal (39) generated upon activation of any one of the switches (31) to (34). 37)
It will be lit if it is determined directly by

Doors (27) and (28) are locked and the car (2
If there are passengers in the cabin of 6), these doors (271 (28)) can be opened directly and mechanically, usually by means of levers provided in the cabin and mechanically actuated. This lever actuates the end (18) of the lever (16) in FIG.
7) actuates the pin (4) as well as the lever (9).

As shown by the broken line in Figure 1, a well-known type of safety lever (8
0) makes it possible to prohibit the rear door (28) from being opened from inside the passenger compartment. The safety lever (80) is
It is rotatably mounted on the frame (7) and has an end (81) acting on a portion of the lever (16) for locking.

When one of the doors (27) or (28) is opened by mechanical actuation from inside the passenger compartment, the corresponding switch (2
3) (23') (23") or (23"') is turned off, even if the central control unit h (83) is blocked (
Even if an attempt is made to disable the operation of blocks (41) to (44) and (66), the control circuit (40)
) (75) to enable the control block of each gear motor unit (14). In this way, the inhibited state of the blocks (41) to (44) and (66) is released when either the door (27) or (28) is opened, so the driver can press the switch ( 31)(
31'), (32)(32'), (33N33')
Even if the operation key of the car is left behind in the car (2

7) Keep (28) openable, while block (
66) and the trunk lid (
29) serves to keep the lid (72) closed, a so-called "garage" function similar to the other side of the block (68) that keeps the gear motor (70) in the closed state of the lid (72). . In fact, the actuation of the switch (58') sends a signal to the block (59), which outputs a signal (61) which directly controls the block (65), which in turn outputs a signal (61) which directly controls the block (65). 66) is prohibited and the block (68
) is driven and the hook is loaded with money (71). In use, the switch (58) outputs a signal (60) from the block (59) to the block (62). The block (62) then switches the switches (31') (32'(33') as described above depending on the presence or absence of the signal (51).
or (34') is evaluated.

In case the power supply to the above-mentioned control system for controlling the various locks (1) installed on the car (26) is stopped, and to avoid a situation where the user cannot enter the inside of the car (26). , one of the locks (1) is

λsr, 1-M 7-7, Yuri-ichi may be provided with terminals for electrical connection for the plate battery, or a lock (1) provided on the door (27) or (28). ) may be provided with one end of a lever actuated in a mechanical manner.

The advantages obtained by the electric lock and the control system applied to the vehicle are clear from what has been said above. In fact, in order to unlock the electric lock (1), a push button switch (45N46H471 (48) or (67)
When Yuri "-" applies pressure, a constant light manual force is required from the user. A change is required in the mechanical actuation force required to unlock the lock (1). Even if the
It can be used for soundproofing and other benefits.

Furthermore, there is a push button switch (45N46) that controls unlocking.
) (47) (48) or (67) does not need to be directly and mechanically activated to the unlocking mechanism of the electric lock (1), so it can be placed in the most convenient location without being subject to positional restrictions. can be placed, giving the designer a wide range of design variant possibilities.

Various work functions for the control system of the various locks (1) installed in the automobile (26), such as simultaneous locking of all or part of them, unlocking display, etc., can be performed extremely easily by the electric and electronic control unit (83). The construction of the mechanical parts of the lock (1) can be fundamentally simplified, since this can be achieved in this way.

The pushbutton switches (45), (46), (47), (48), and (67) are provided in the blocks (41), (42), (43), (44), and (66) by filtering possible noise signals. A circuit that allows the operation determined only by the signal generated by the operation prevents the lock from being unlocked unless necessary.

Finally, it is clear that there may be variations and modifications to the above-described embodiments of the lock of the invention and the control system for the vehicle without departing from the scope of the invention.

For example, the push button switch (45) for unlocking control ('
16) (47) (48067) and two position switch (31) (31') (32) (32°H33) (3
3' (34) (34') can be manufactured in different ways and may also be replaced with a circuit activated by a 1ill fil signal sent through the air by means of ultrasound, for example.

Furthermore, the automobile (26) may be equipped with an electric lock different from the electric lock (1) described above, and for example, the hood j/i! It may be equipped with a lock for locking, and furthermore, for example, the front door (27
) but not the rear door (28).

The mechanism for returning the unlocking lever (9) to its rest position at the end of the operation of the gear motor (14) is, for example, a block (41) (421) rather than constituted by a spring (15).
(43), (44), and (66) may be replaced by a crank and/or link connection activated by a set time determined by a timer circuit or by a rotational movement of a gear motor unit. Or, these blocks have a gear motor unit (1
A relay and timer circuit may be provided to determine the electrical supply for rotation in the opposite direction to 4).
