The present invention relates to a motor vehicle door latch device.
A motor vehicle door latch device comprises an engagement mechanism engaging with a striker of a vehicle body to hold a door closed, and an operating mechanism for operating the engagement mechanism, and is classified to a manually releasing type for enabling the engagement mechanism to be released by mechanical elements such as a lever and a link based on operation of mechanical elements such as an outside handle or an inside handle on the door and an electrical release type for enabling the engagement mechanism to be released by electric elements such as a motor for driving on the basis of electric operating elements such as a switch on the door.
As described in JP3758929B2, the manually releasing type door latch device comprises a locking motor, and a locking mechanism (operating mechanism in JP3758929B2) that comprises a lever and a link for selectively shifting an unlocking state that validates a door-opening action of the mechanical operating elements to enable the engagement mechanism to be released based on the locking motor and a lock state that invalidates the opening action enabling the engagement mechanism not to be released.
The electrically releasing type of door latch device is described in JP4145774B2 and JP4617588B2.
The door latch device in JP4145774B2 comprises an electric release mechanism comprising a releasing motor that can be driven with a door-opening switch on the door and an output lever that is rotated by the motor to release the engagement mechanism; and an opening lever pivotally mounted via the same axis for the output lever. A ratchet lever for releasing the engagement mechanism is connected to an outside operating lever positioned outside the vehicle and is not used during usual operation. The opening lever is connected to an inside lever inside the vehicle via a second wire. A control device in the vehicle electrically shifts an unlock state for validating a door-opening switch and a lock state for invalidating it.
In the door latch device in JP414577482, ID signals are identified through a wireless communication between an electronic key (portable device in JP4145774B2) carried by a regular user for the car and an authenticating portion in the car, and it is authenticated that the regular user approaches the car. The door-opening switch is operated by the regular user and a release motor is driven. The engagement mechanism is released by a ratchet lever to enable the door to open. If an electric system including a linear motor is broken, an external mechanical operating element or an internal mechanical operating element is operated whether the control device control the unlock state or the lock state, to actuate the ratchet lever to release the engagement mechanism to enable the door to open. In this structure, if the regular user who approaches the car is not authenticated by the authenticating portion through the ID signal, a passenger without the electronic key cannot open the door.
The motor vehicle door latch device in JP4145774B2 mainly comprises a releasing motor, an opening lever that can be rotated by the motor; an inside lever connected to an internal mechanical operating element (“inside handle” in JP4145774B2) on the door inside the vehicle; an opening link for enabling the engagement mechanism to be released by the inside lever and the opening lever; and a key lever connected to a key cylinder on the door outside the vehicle: Besides electric control of a control device, the door is shifted to an unlock state and a lock state by actuating the opening link for locking, thereby invalidating an opening action of the internal mechanical operating elements.
In the door latch device in JP4145774B2, when the control device controls the unlock state, an opening switch on the door is operated and a releasing motor is controlled to release the engagement mechanism to enable the door to open. If trouble occurs in electric systems, regardless of the unlock state or lock state, the key cylinder releases the engagement mechanism to enable the door to open.
In the manually releasing motor vehicle door latch device, the engagement mechanism and basic structure for the operating mechanism (structure except an internal operating system connected to an internal mechanical operating element or an inside handle) are used in common, and various designs are determined to differ internal operating systems for the internal mechanical operating element.
For example, as the internal operating system, in a door opening action of the internal mechanical operating element when a locking mechanism that comprises mechanical element is in a lock state, the door cannot be opened even if the internal mechanical operating element is operated to open the door (Design 1 applied to the front door and the rear door); the locking mechanism is shifted to the unlock state by the first door-opening action of the internal mechanical operating element, and the door can be opened by the second door-opening action (Design 2 applied to the front door); the locking mechanism is shifted to the unlock state with releasing of the engagement mechanism by a one-time door-opening action of the internal mechanical operating element (Design 3 applied to the front door); the door cannot be opened based on a door-opening action of the internal mechanical operating element when the locking mechanism is in the unlock state and the childproof mechanism is in the childproof lock state (Design 4 applied to the rear door): and the locking mechanism is shifted from the lock state to the unlock state by a door-opening action of the internal mechanical operating element besides the Design 4 (Design 5 applied to the rear door)
However, in the motor vehicle door latch device, in order to improve a door-opening activity of a regular user with an electronic key, to improve dealing with trouble in the electric system, and to improve a door-opening activity of a passenger without the electronic key, it is preferable to comprise the releasing motor in JP4145774B2 or JP4617588B2 together with the locking mechanism and locking motor that comprises the mechanical elements in JP3758929B2. But in order to provide the releasing motor, the locking motor and the locking mechanism together and to set each of the designs for the internal operating system, the structure of each of the elements of the internal operating system is different in each of the Designs, and it becomes difficult to use the basic structure of the operating mechanism in each of the Designs.
In view of the disadvantages, it is an object of the invention to provide a motor vehicle door latch device that comprises a releasing motor, a locking motor and a locking mechanism and enables an operating mechanism to be used.
One embodiment of the present invention will be described with respect to drawings.
In
A rear door RD comprises a door latch device 1R for a rear door for holding the rear door closed; an outside handle OH as an external mechanically operating element on the door outside the vehicle; a detecting switch SW as an internal mechanical operating element on the door inside the vehicle; and a locking knob (not shown) for shifting the locking mechanism into the lock state and unlock state from the inside of the vehicle. The following Design 4 or 5 is set to the door latch device 1R.
The detecting switch SW as electric detecting element is disposed on a front surface, a back surface or close to the outside handle (OH), and comprises an electrostatic capacitance touch switch that detects that a finger of a user is touched. The regular user with an electronic key exclusively used for the car approaches within a predetermined area around the car, and an ID signal is identified though a wireless communication between the electronic key and a receiver of the car V. Thus, only when it is authenticated that the regular user comes to the car V, the detecting switch is electrically controlled by an ECU (electronic control unit) of the car V so that the user may be detected. The detecting switch is not limited to the touch switch, but may be a proximity switch detecting that part of a human body comes.
Then, the basic structure of the door latch device 1F, 1R will be described.
The door latch devices 1F, 1R are the same to each other in the basic structure except part (including an internal operating element later described). Thus, the door latch device 1F in the Design 1 is described, and the door latch device 1R is interpreted without special description by replacing “door latch device 1F” with “door latch device 1R” and “front door FD” with “rear door RD”. Each of the Designs will be described after the basic structure common with each of the Designs and actions therefor are described,
The internal operating elements denote a lever and a link that connect a door-opening action of the inside handle IH, which will be described later.
The directions in the following description show states where the door latch devices 1F, 1R are attached in the doors FD, RD respectively.
The door latch device 1F comprises an engagement unit 2 with an engagement mechanism mounted in the front door FD for holding the front door FD closed by engaging with a striker S of the vehicle body; and an operating unit 3 with the locking mechanism comprising mechanical elements, such as a lever and a link, for shifting the front door FD to the lock state and the unlock state.
In
The latch 5 is pivotally mounted in the body 4 via a latch shaft 8 that lies longitudinally of the vehicle, and comprise a full-latch engagement portion 51 and a half-latch engagement portion 52 that can engage with the ratchet 6, and engagement groove 53 that can engage with the striker S which enters a striker-entering groove 41 of the body 4.
In
With closing of the front door ED, the latch 5 rotates from an open position (a position where it rotates clockwise from
The ratchet 6 is pivotally mounted under the striker-entering groove 41 within the body 4 via a ratchet shaft 9 that lies longitudinally of the vehicle and is urged by a spring (not shown) in an engaging direction (counterclockwise in
The inertia lever 37 is pivotally mounted via a shaft 31 such that a center of gravity is positioned at the center of the shaft 31, and is urged any time clockwise by a spring 38 in which one end engages with a projection 371 on a front face, so that the inertial lever 37 is at rest in a standby position in
Thus, when a force of inertia for turning the ratchet 6 in a releasing direction (clockwise in
When the opening lever 7 and the ratchet 6 are rotated by an outside lever 34 (later described) in the releasing direction, the end of the opening lever 7 comes in contact with the projection 371 counterclockwise in
In
Then, an operating unit 3 will be described as below.
The operating unit 3 comprises a first L-shaped synthetic-resin cover 10 fixed to the body 4 to cover a front surface of the body 4; a second synthetic-resin cover 11 that closes a side of the first cover 10 facing the interior of the vehicle; a synthetic-resin waterproof side cover 12 that closes an upper half of the second cover 11 from the interior of the vehicle; a waterproof top cover 13 that covers a top joining surface of the first cover 10 and the second cover 11; and an operating mechanism (not numbered) in the housing.
“In the housing” in the description denotes a storage space formed between a side of the first cover 10 perpendicular to a front face of the body 4 and a side of the second cover 11 opposite the side of the first cover 10.
In
The inside lever 19 of the internal operating system is set in each Design as below. The operating mechanism of the operating unit 3 comprises elements except the inside lever 19 (including the key lever 20 in the rear-door door latch device 1R) from the basic elements.
In this embodiment, the locking worm wheel 15, the locking lever 16 and the knob lever 17 as mechanical elements constitute the locking mechanism.
“An unlock state” in the following description means that the locking lever 16, the knob lever 17 and the opening link 18 are in an unlock position respectively, and “a lock state” means that the locking lever 16, the knob lever 17 and the opening link 18 are in a lock position respectively. The locking mechanism is not limited to this embodiment, but the locking lever 16 may be connected to the locking knob without the knob lever 17.
The releasing motor 22, the releasing worm wheel 23 and the electric release lever 24 form an electric releasing mechanism.
The locking motor 14 is held in the housing, and a case 14a (yoke) is above a striker-entering line X in
The locking motor 14 is disposed in the housing such that the case 14a is above the striker-entering line X. So rainwater through the striker-entering groove is prevented from coming into the case 14a.
The distribution plate 25 is integrally formed with a coupler 251 connected to an external connector or wire (not shown) connected to a vehicle battery (not shown) and an ECU. At a side of the distribution plate 25 opposite the outside of the vehicle, electric circuits for supplying power and signals into the housing are fixed in the housing to cover the case 14a of the locking motor 14 from the inside of the vehicle. The distribution plate 25 is electrically connected to terminals of the locking motor 14 and the releasing motor 22, and to the external connector connected to the coupler 251 so that the locking motor 14 and the releasing motor 22 may be controlled by the ECU.
The locking worm wheel 15 is pivotally mounted in the housing via a shaft 26 that lies transversely of the vehicle below the case 14a of the locking motor 14 and meshes with a worm 141 mounted on an output shaft 14b of the locking motor 14. Thus, the worm wheel 15 is rotated clockwise or counterclockwise by the locking motor 14 from a neutral position (such as in
The knob lever 17 is pivotally mounted to a side of the second cover 11 via a shaft 111, and a connecting arm 171 that extends downward is connected to a manually-operating locking knob via a connecting member 28 comprising a Bowden cable. So, based on an unlocking action and a locking action of the locking knob, the knob lever 17 rotates counterclockwise from an unlock position in
After the knob lever 17 is connected to the second cover 11 in
The locking lever 16 is pivotally mounted in the housing via a shaft 101 that projects inward of the vehicle from an inner surface of the first cover 10, and teeth 161 of the locking lever 16 mesh with teeth 151 of the locking worm wheel 15. An upper part of the locking lever 16 is joined to the key lever 20, and a connecting projection 162 at an upper front part is connected to a connecting hole 172 of the knob lever 17 through an arc-shaped hole 112 of the second cover 11. The locking lever 16 has an arm 164 with a guide wall 165 that extends downward from a center of rotation. A shaft 101 or a center of rotation of the locking lever 16 is disposed above the striker-entering line X in the housing.
Thus, according to rotation of the key lever 20 with the key cylinder, rotation of the knob lever 17 with the locking knob and rotation of the locking worm wheel 15 with the locking motor 14, the locking lever 16 can rotate from an unlock position in
The holding member 29 comprises a torsion spring a coil of which is supported by a cylindrical support 102 (in
The locking lever 16 stops at the unlock position and the lock position by contacting a part of the locking lever 16 to a rubber stopper (not shown) fixed to the inner surface of the first cover 10.
On an upper circumference of the locking lever 16, there is formed a cam surface 163 which contacts a detecting portion of a detecting switch 30 of the distribution plate 25. The detecting switch 30 is in sliding contact with the cam surface 163 relatively, thereby supplying a signal corresponding to the unlock state/lock state of the locking mechanism. The outputted signal is transmitted to the ECU via the circuits on the distribution plate 25.
The opening link 18 has a connecting hole 182 in a lower rotary portion 181, and a flat connecting portion 211 at the end of the outside lever 21 is inserted into the connecting hole 182. Hence, the opening link 18 is coupled to the connecting portion 211 of the outside lever 21 to rotate by a certain angle, and an upper coupling projection 183 is coupled to the arm 164 of the locking lever 16. With a motion of the locking lever 16 between the unlock position and the lock position, the opening link 18 rotates from an unlock position in
Furthermore, in the middle, the opening link 18 has a releasing portion 184 which can contact the released portion 71 of the opening lever 7 from below, in the unlock position in
One end of the torsion spring 36 engages with the opening link 18, and the other end engages with the connecting portion 211 of the outside lever 21. So, an urging force is applied to the opening link 18 anytime in the unlocking direction (clockwise in
The coupling projection 183 of the opening link 18 is connected to the arm 164 of the locking lever 16 such that the coupling projection 183 of the opening link 18 can slide vertically along the arm 164 of the locking lever 16 and can contact the guide wall 165 only when the locking lever 16 rotates in a locking direction (counterclockwise in
In the unlock state in
In the lock state in
The outside lever 21 is pivotally mounted vertically at a front lower part of the body 4 via the shaft 31 which lies longitudinally of the vehicle, and the connecting portion 211 is connected to the opening link 18 as above. A connecting portion 212 at the inner end is connected to the outside handle OH via a vertical connecting member (not shown). Based on a door-opening action of the outside handle OH, the outside lever 21 rotates against the urging force of a spring (not shown) in a releasing direction (counterclockwise in
In the housing, a case (yoke) 22a of the releasing motor 22 is below the striker entering line X, and an output shaft 22b pivotally mounted to the case 22a is disposed backward and downward. The regular user with the electronic key comes within a predetermined area around the motor vehicle V, and an ID signal is matched through wireless communication conducted between the electronic key and a receiver in the motor vehicle V. When it is authenticated that the regular user comes around the motor vehicle V, the releasing motor 22 is driven by turning on the detecting switch SW because the user contacts or approaches the detecting switch SW.
Because the releasing motor 22 is disposed below the striker-entering line X, rainwater that comes through the striker-entering groove 41 likely attaches to the releasing motor 22, but the output shaft 22b of the releasing motor 22 is disposed obliquely backward and downward. So rainwater that comes into the case 22a can be minimized.
The releasing worm wheel 23 is like a disc and is pivotally mounted in the housing via the shaft 31 which lies transversely of the vehicle. The worm wheel 23 meshes with a worm 221 fixed to the output shaft 22b pivotally mounted to the case 22a of the releasing motor 22. Based on the drive of the releasing motor 22, the worm wheel 23 is rotated clockwise by a certain angle from a set position (such as a position in
The shaft 31 for mounting the releasing worm wheel 23 pivotally is below the case 22a of the releasing motor 22 and disposed behind the output shaft 22b.
An electric release lever 24 is pivotally mounted via a shaft 102 (release shaft) in the middle in the housing, and comprises a first arm 241 in which a front end can come in sliding contact with a cam surface 231 of the releasing worm wheel 23 and a second arm 242 in which a rear end can come in contact with a released portion 71 of the opening lever 7 from below.
In the housing, the shaft or a center of rotation of the electric release lever 24 is disposed below an upper half of the case 22a and the striker-entering line X behind the shaft 31 in front of the opening lever 7.
For example, in
When the regular user with the electronic key comes within a predetermined area around the car V and it is authenticated that the regular user approaches the car V by identification through a wireless communication between the electronic key and the receiver in the car V, the ECU makes the detecting switch usable, turns on the detecting switch SW by contacting or approaching the detecting switch SW and controls the releasing motor 22 to enable the front door FD to open. When the locking mechanism is in the lock state, the locking motor 14 is controlled and shifted to an unlock state after the releasing motor 22 stops driving.
A position of each element that constitutes a basic structure of the operating mechanism is set as below:
The locking mechanism and an electric release mechanism are disposed above and below the striker-entering line X respectively in the housing, and each of the elements can be arranged orderly. Because the shaft 102 is located at the foregoing position, the releasing motor 22, the releasing worm wheel 23 and the electric release lever 24 can be arranged longitudinally of the vehicle to minimize downward projections, thereby making the housing smaller and, in turn, making the door latch device 1F smaller.
Then, basic movements of the door latch device 1F will be described.
When the front door is fully closed and the locking mechanism is in an unlock state, each element of the operating mechanism is held in
In the unlock state in
When the front door FD is fully closed and the locking mechanism is in the lock state, the elements of the operating mechanism are held in
In the lock state in
Whether the locking mechanism is in an unlock state or a lock state when the front door FD is fully closed, the ECU does not authenticate the regular user and the releasing motor cannot be driven even if the passenger without the electronic key operates the switch SW.
Thus, the passenger without the electronic key can open the front door FD by operating the outside handle OH of the front door FD only when the front door FD is in an unlock state.
Specifically, when the outside handle OH is operated to open the door, the door-opening action is transmitted via a connecting member (not shown) to the outside lever 21, which is released counterclockwise in
In
The outside handle OH on the front door FD is also usable as outside mechanical operating element for opening the door in an emergency if the releasing motor 22 is incapable of driving due to failure in the releasing motor 22 or an electric system therefor. However, in case of the lock state, it is necessary to shift the locking mechanism to the unlock state with power of the locking motor 14 due to unlocking operation of the key cylinder KO and unlocking operation of the switch in the electronic key.
The structure and action of an internal operating system in each Design will be described.
The internal operating system in Design 1 comprises the inside lever 19 as shown in
The connecting member 33 passes between the case 14a of the locking motor 14 located at an upper part of the housing and the case 22a of the releasing motor 22 located at a lower part, and is connected to the first arm 191 of the inside lever 19. So, the connecting member 33 is not over the cases 14a, 22a with a greater thickness transversely of the vehicle, thereby reducing a thickness along the width of the vehicle.
In the unlock state in
In the lock state in
Thus, in the door latch device 1F in the Design 1, when the locking mechanism is the lock state, the locking mechanism is shifted to the unlock state, and then, the inside lever 19 is rotated by the inside handle IH of the front door FD, so that the front door ED can be opened.
An internal operating system in the Design 2 comprises an inside lever 19A in
The unlocking portion 193 is formed on the upper end of the first arm 191 as a shape which can contact a part of the lower portion of the connecting arm 171 of the knob lever 17.
In the unlock state in
In the lock state in
With the releasing action of the inside lever 19A, the opening link 18 goes across upward in front of the released portion 71 of the opening lever 7 without contact, and the opening link 18 rotates with the locking lever 16 in an unlocking direction. So, in
In the door latch device 1F, when the locking lever 16 rotates from the unlock position to the lock position, the guide wall 165 of the locking lever 16 contacts the coupling projection 183 of the opening link 18 to move the opening link 18 to the lock position. But, when the locking lever 16 rotates from the lock position to the unlock position, the opening link 18 is rotated to the unlock position by the torsion spring 36 without depending on a contact relationship between the guide wall 165 and the coupling projection 183. Even if the once-stop state as above occurs, the locking lever 16 can rotate to the unlock position against the torsion spring 36 while the opening link 18 is still at rest in a position before the unlock position in
In
After shifting to the unlock state, the engagement mechanism is released by the inside handle IH again, so that the front door FD can be opened.
When the door latch device 1F in the Design 2 is in the lock state, the device is shifted to the unlock state by the first door-opening action of the inside handle IH, and the engagement mechanism is released by the second door-opening action of the inside handle IH, so that the front door FD can be opened.
An internal operating system in the Design 3 comprises an inside lever 19B in
The unlocking portion 193 which is the same as in the Design 2 is formed at the upper end of the first arm 191 and as a shape which can contact part 173 of the connecting arm 171 of the knob lever 17. The inside lever 19b is released (rotating counterclockwise in
In the unlock state in
In the lock state in
In the door latch device 1F in the Design 3, even if the locking mechanism is in the lock state, the locking mechanism is shifted to the unlock state by one-time opening action of the inside handle IH, and the engagement mechanism is released, so that the front door ED can be opened.
The Design 4 is set to a door latch device 1R for a rear door. In
The first and second inside levers 19C, 19D are pivotally mounted via the shaft 102 which is the same axis for the electric release lever 24.
In the first inside lever 190, the upper end of the first upward-extending arm 191 (corresponding to the first arm 191 of the inside lever 19 in the Design 1) is connected to the inside handle IH of the rear door RD via the connecting member 33, and the first inside lever 190 is released counterclockwise, from the set position in
The second inside lever 19D has a vertical elongate opening 196 partially over the control hole 195 of the first inside lever 190 and a second arm 192 that extends obliquely downward(corresponding to the second arm 192 of the inside lever 19 in the Design 1).
The childproof operating lever 19E is pivotally mounted via a shaft 103 in the housing, and can rotate between a childproof unlock position in
The shaft 102 vertically slides in a vertical elongate hole 19Fa of the connect link 19Fa; a lower projection 19Fb slides in an arc-shaped hole 197 of the childproof operating lever 19E; and an upper projection 19Fc slides in a control hole 195 and an elongate hole 196. Hence, when the childproof operating lever 19E is in the childproof unlock position in
“A childproof unlock state” described below denotes that the childproof operating lever 19E is in a childproof unlock position to enable an action of the first inside lever 19C to transmit the second inside lever 19D, and “a childproof lock state” denotes that the childproof operating lever 19E is in a childproof lock position not to enable an action of the first inside lever 190 to transmit to the second inside lever 19D.
An internal operating system in the Design 4 will be described.
In
When the locking mechanism in the lock state and the childproof mechanism is in the childproof unlock state, the first inside lever 180 and the second inside lever 19D are released, and the opening link 18 is released upward from the set position. But as well as the Design 1, the releasing portion 184 of the opening link 18 swings without contact with the released portion 71 of the opening lever 7, so that the door RD cannot be opened. Thus, in order to open the rear door RD due to a door-opening action of the inside handle IH as well as the Design 1, the locking motor 14 is driven by an unlocking of the locking knob inside the vehicle or with the switch inside the vehicle, the locking mechanism is shifted to the unlock state, and thereafter it is necessary that the door should be tried to open by the inside handle.
In
=Design 5>
The Design 5 is set to a door latch device 1R for a rear door. In
The first inside lever 19G is pivotally mounted via a shaft 102 which is the same axis for the electric release lever 24. The upper end of the first arm 191 extending upward is connected to the inside handle IH of the rear door RD via the connecting member 33, and due to a door-opening action of the inside handle IH, the first inside lever 19G is released counterclockwise from the set portion in
The second inside lever 19D, the childproof operating lever 19E and the connect link 19F are the same as those in the foregoing Design 4, with the same numerals as those in the Design 4 in
The internal operating system in the Design 5 will be described.
In
When the locking mechanism is in the lock state and the childproof mechanism is in the childproof unlock state, the door is tried to open by the inside handle IH, and the first inside lever 19G and the second inside lever 19D are both released. As well as the Design 2, based on releasing of the first inside lever 19G due to a first door-opening action of the inside handle IH, in
In
When the locking mechanism is in the lock state and the childproof mechanism is in the childproof lock state, the first inside lever 19G is released due to a door-opening action of the inside handle IH of the rear door RD. Based on the releasing action, the unlocking portion 193 of the first inside lever 19G comes in contact with the part 173 of the knob lever 17, thereby shifting to the unlock state. The childproof lock state is still kept, and if it is not shifted to a childproof unlock state by the childproof operating lever 19E, the rear door RD cannot be opened by the inside handle IH. Because the locking mechanism is shifted to the unlock state, the rear door can be opened by the outside handle OH on the rear door RD outside the vehicle.
When the childproof mechanism is in the childproof lock state, the door latch device 1R in the Design 5 cannot open the rear door RD even if the rear door RD is tried to open by the inside handle IH, whether the locking mechanism is in the unlock state or the lock state. When the locking mechanism is in the lock state, it can be shifted to the unlock state by the inside handle IH on the rear door RD.
From the above, the shaft 102 for pivotally mounting the electric release lever 24 in the housing is positioned within the range C behind the releasing worm wheel 23 below the locking lever 16 in front of the opening link 18 and the opening lever 7, and an axis for the inside lever 19, 19A, 19B, 19C, 190, 190 is the same as the shaft 102 for the electric release lever 25. Without changing a position of each element forming the basic structure of the operating mechanism, the electric release lever 24 can actuate each element as below:
Thus, the basic structure for the operating mechanism is used among the Designs. The releasing motor 22, the releasing worm wheel 23, the electric release lever 24 and the inside lever 19 (19A, 19B, 190. 19D, 19G) can be arranged orderly thereby making the housing and the door latch device 1F smaller.
