Thereby, the strength of the oscillating blade 82 can be ensured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat detecting device for detecting whether or not a child seat is mounted on a vehicle seat.

[0002]

2. Description of the Related Art Examples of a connection structure of a child seat for attaching a child seat to a vehicle seat include a structure called a hook type and a structure called a connector type. Hereinafter, the connection structure of both the hook type and the connector type will be briefly described.

[0003] The hook type is provided with a belt whose base end is mechanically connected to the child seat side and which can shorten the length from the connection portion with the child seat to the front end by tightening. The hook is fixed. The hook is a hook body whose distal end is curved in a substantially U-shape. At the base end of the hook main body, a lock piece is pivotally supported so as to be pivotable in a direction in which the distal end comes into contact with and separates from the distal end of the hook main body. An urging member is provided for urging the lock piece in a direction in which the tip of the lock piece approaches the tip of the hook body. On the other hand, between the seat cushion and the seat back of the vehicle seat, a bar-shaped bar body that is axially oriented along the width direction of the seat becomes a bottom and has a substantially U-shape that opens toward the vehicle rear side. A lock bar is provided.

In the above hook type, when the hook main body is pressed in a direction approaching the bar main body with the lock piece of the hook applied to the bar main body of the lock bar, the urging member is pressed by the pressing reaction force from the bar main body. The lock piece pivots against the force and the tip of the lock piece separates from the tip of the hook body. When the bar body of the lock bar passes between the tip of the lock piece and the tip of the hook body in this state, the pressing reaction force from the bar body is released, and the lock piece pivots with the urging force of the urging member. Then, the distal end of the lock piece and the distal end of the hook body again come into contact with each other, so that the bar body enters the inside of the annular portion formed by the hook body and the lock piece. In this connection state, the child seat can be fixed to the vehicle seat by appropriately tightening the belt.

On the other hand, the connector type is provided with a square rod-shaped frame extending from a child seat. A bar insertion opening is formed at the front end of the frame at the front end of the frame. The inner width of the bar insertion opening is slightly larger than the outer diameter of the bar main body of the lock bar, and the bar main body can be accommodated inside the bar insertion opening. A lock member called a striker is rotatably supported inside the frame so as to be rotatable around the width direction of the frame. The striker includes an abutting piece positioned corresponding to the bar insertion port in an unlocked state, and a lock piece positioned corresponding to the bar insertion port in a locked state.
Further, the striker is urged by the urging means in a direction to be in a locked state, and in the locked state, the striker cannot be rotated except for a predetermined release operation.

In this connector type, a lock bar similar to the hook type is also provided, and the bar main body of the lock bar is inserted into the inside of the bar insertion port, and the bar main body is brought into contact with the contact piece. Further, when the frame (that is, the child seat) is moved to move the bar body to the bottom side of the bar insertion opening, the contact piece is displaced by the pressing force from the bar body, and the position of the biasing means is shifted. When the contact piece moves to this point, the locking portion moves to the opening side of the bar insertion opening portion from the bar main body by the urging force of the urging means, and the locking portion closes the opening side of the bar insertion opening portion. Thus, the child seat can be fixed to the vehicle seat.

It is generally well known that when a child seat is mounted on a seat, it is preferable not to operate an airbag device corresponding to the seat on which the child seat is mounted. Correspondingly, an airbag computer for controlling the airbag device by providing a detection device for detecting whether or not the child seat is mounted, and detecting a signal when the detection device detects that the child seat is mounted to the seat. There is also a child seat detection device that prevents the airbag device corresponding to the seat with the child seat from being operated in any case when the vehicle is received.

[0008]

However, in the conventional child seat detection device, only one type of detection can be performed due to the difference in shape and size between the connector frame and the hook. There is a problem that the selection range of the child seat when purchasing a car is narrowed.

An object of the present invention is to provide a child seat detecting device capable of detecting a child seat regardless of whether the connection structure is a connector type or a hook type in consideration of the above fact.

[0010]

According to the first aspect of the present invention, the locking portion of the locking means provided on the child seat is located closer to the mounting direction of the child seat with respect to the vehicle seat than the mounting portion provided on the vehicle seat. By being located, the attachment portion restricts displacement of the lock portion in a release direction opposite to the mounting direction, and is applied to a child seat connection structure that restricts movement of the child seat in the release direction with respect to the vehicle seat. A child seat detection device for detecting the child seat mounted on the vehicle seat, wherein the child seat is pivotable around the axis with the left-right direction of the seat as an axial direction, and the leading end side thereof in the initial state is in the mounting direction. A swing member disposed so as to be located on a movement locus of the lock portion, and attaching the swing member to the initial state. Biasing means, and position detecting means for detecting the rocking of the rocking member due to the pressing from the locking means, to which the locking part has moved to a position where the movement is restricted by the mounting part. Features.

According to the child seat detection device having the above-described configuration, when the child seat is mounted on the vehicle seat, if the locking portion of the locking means provided on the child seat is positioned closer to the mounting direction than the mounting portion on the vehicle seat side, the swinging motion is increased. The moving member is pressed by the locking means including the locking portion against the urging force of the urging means, and is moved in the left-right direction of the seat (in more detail, when the seat is facing the front of the vehicle, When the front direction of the occupant sitting on the seat is forward of the vehicle, the swing member swings as an axial direction (ie, the swing member is pushed away by the lock portion). When the rocking member is pressed by the locking means and rocks, the displacement of the rocking member is detected by the detecting means. That is, by detecting the displacement of the swinging member, the lock portion is located closer to the mounting direction than the mounting portion, and the movement in the release direction is restricted by the mounting portion, that is, the child seat is securely attached to the vehicle seat. The attachment is detected.

Here, the above-described operation can be performed without setting the axial direction of the pivot axis of the swing member in the left-right direction of the seat.
For example, the height direction of the seat may be the axial direction of the pivot axis of the swing member. However, in the case where the above-described locking means is provided between the seat back and the seat cushion of the seat, the gap between the seat back and the seat cushion along the vertical direction of the seat is extremely large. Small, for example, when considering the provision of a swing member having the axial direction in the height direction of the seat in such a configuration, the length of the swing member in the pivot axis direction is extremely small, and the strength of the swing member is reduced. It will be smaller. On the other hand, in the case where the axial direction of the pivot axis of the swing member is the left-right direction of the seat, the pivot axis length of the swing member can be sufficiently secured, and the strength of the swing member can be secured.

According to a second aspect of the present invention, in the child seat detecting device according to the first aspect, the locking means that moves in the mounting direction is provided at a position where movement of the locking portion by the mounting portion can be restricted, and It is characterized in that it is provided with guide means for guiding to a position where it can contact the swing member.

According to the child seat detecting device having the above structure, since the locking means moves while being guided by the guide means, it is possible to surely restrict the movement of the locking part by the mounting part. The rocking member is reliably rocked by the lock means.

A restricting mechanism (not shown) for restricting the rotation of the striker 38 is housed inside the frame 34, and the bar body 20 of the striker 38 is inserted inside the bar insertion opening 36 along the width direction of the frame 34. The restricting mechanism restricts the rotation of the striker 38 in a state where the striker 38 is swiveled until is seen. This restriction mechanism can be released, for example, by pressing a release button (not shown) provided on the base end side of the frame 34 (that is, the main body side of the child seat 30).

(Structure of hook type connecting device 52)
As shown in FIG. 2, the connecting device 52 is a so-called “hook-type connecting device” having a hook 54. The hook 54 includes a hook body 56 as a lock portion curved in a hook shape (that is, a substantially J-shape). Hook body 56
Is locked to a distal end of a long belt-like belt 58 (not shown). The base end side of the belt 58 is penetratingly engaged with each of a pair of annular members provided on the child seat 30, and by pulling the base end of the belt 58, the length from the child seat 30 to the front end of the belt ( That is, the length up to the hook body 56) can be shortened, and
By loosening the through-engagement state with the pair of annular members and pulling the base end side toward the distal end, the length from the child seat 30 to the distal end of the belt (ie, the hook body 56)
Length) can be lengthened.

On the base end side of the hook body 56 in the longitudinal direction, a base end of a lock piece 60 formed in a rod shape or a tongue piece is rotatable around the width direction of the hook body 56.
6. The tip of the lock piece 60 comes into contact with and separates from the tip of the hook body 56 by pivoting, and contacts the tip of the hook body 56 by pivoting in a direction approaching the tip of the hook body 56, so that the lock piece 60 Further pivoting is limited by the hook body 56. In this rotation restricted state, the hook main body 56 and the lock piece 60 become annular.

The lock piece 60 is urged by an urging member (not shown) in a direction in which the tip thereof approaches the tip of the hook body 56. In a normal state, the lock piece 60 is in the above-described turning restricted state.

(Configuration of Child Seat Detecting Apparatus 10)
On the other hand, as shown in FIG. 3, the present child seat detection device 10 includes a support 72 disposed below the lock bar 14. The support body 72 has a concave cross-section opening upward to the passenger seat 24 and has side walls 7 at both ends in the width direction.
4, 76, a cylindrical portion 78 is formed through which the above-mentioned leg portions 16, 18 respectively penetrate.
Are penetrated, so that the support 72 is supported by the lock bar 14.

A shaft 80 is bridged between the side walls 74 and 76 of the support 72 and on the front end side of the support 72, and a swinging wing 82 as a swinging member is pivotally supported. I have. The oscillating wing 82 is a plate-like member having a widthwise direction along the axial direction of the shaft 80 (that is, the left-right direction of the passenger seat 24), and the whole or a part thereof is formed of a magnetic material such as metal. . The oscillating wing 82 is formed on the shaft 8 such that the tip side in the turning radial direction generally faces the rear side of the passenger seat 24.
0 supported. Therefore, one swing of the swinging wing 82 is restricted by the support 72. On the other hand, since the swinging feather 82 has a width smaller than the distance between the leg 16 and the leg 18, the swinging feather 82 turns between the leg 16 and the leg 18 by turning to the other side. pass. However, the oscillating feather 8
Since the longitudinal dimension of 2 is sufficiently longer than the distance from the shaft 80 to the bar main body 20, the swinging wing 82 pivots by a predetermined angle, so that the longitudinal middle portion of the oscillating wing 82 abuts on the bar main body 20 and pivots. They are also being restricted.

Further, as shown in FIGS. 1 and 2,
The shaft 80 is provided with a torsion coil spring 84 as urging means. One end of the torsion coil spring 84 is locked to the support 72 and the other end is the swinging blade 8.
2 and urges the swinging wings 82 in a direction to contact the bar main body 20. Therefore, if no external force other than the urging force of the torsion coil spring 84 is acting on the swinging wing 82, the swinging wing 82 will always contact the bar main body 20. Hereinafter, the turning position of the swinging wing 82 that contacts the bar main body 20 is referred to as an initial position.

As shown in FIGS. 1 and 2, a magnetic sensor unit 90 as a position detecting means is disposed on the support 72. The magnetic sensor unit 90 includes a magnet (permanent magnet) 92, and forms a predetermined magnetic field around the magnet. The magnetic sensor unit 90 includes a magnetoresistive element 94 disposed at a position where a magnetic field formed by the magnet 92 crosses. The detailed description of the magnetoresistive element 94 is omitted because it is a known technique.

The magneto-resistive element 94 has a known electric resistance value of 3
A bridge circuit is formed together with the two resistance elements, and the change in the electric resistance value of the magnetoresistive element 94 is obtained from the current value of the current flowing through this circuit. The magnetic sensor unit 90 is connected to a computer 96 and has a magnetoresistive element 94.
Is determined by the computer 96 as to whether or not the electrical resistance value of the electronic device has changed. Further, the computer 96 is a starting device 1 of an airbag device 98 provided on the front side of the passenger seat 24 on the vehicle.
When the computer 96 determines that the electric resistance value of the magnetoresistive element 94 has changed, the computer 96 sends a start / stop signal to the starter 100.

The activation device 100 is connected to an acceleration sensor 102 which also forms the airbag device 98.
When detecting the deceleration of the vehicle 22 equal to or more than a predetermined magnitude, that is, the rapid deceleration state of the vehicle 22, the acceleration sensor 102 sends an activation signal to the activation device 100,
Let The activation device 100 that has received the activation signal activates the main body 104 having a bag or the like to inflate and deploy the bag toward the front of the occupant in the passenger seat 24, but when the activation stop signal from the computer 96 is received, , Acceleration sensor 102
The main body 104 is not operated even if the detection of the deceleration is stopped, or the start-up signal from the acceleration sensor 102 is received.

On the other hand, the support 72 is
On the opposite side (that is, above the support 72), a guide 106 as a guide means is disposed. Guide 1
Reference numeral 06 denotes a plate-like base 108 extending in the longitudinal direction along the longitudinal direction of the legs 16 and 18, and the side wall 1 extending from both ends in the width direction of the base 108 toward the lock bar 14 side.
10, 112. The distance between the side wall 110 and the side wall 112 is a dimension corresponding to the larger one of the width of the frame 34 and the hook main body 56 (in the present embodiment, the frame 34 as can be seen from each drawing). , Slightly smaller than the larger width dimension. Moreover, the base 1 along the height direction of the passenger seat 24
The dimensions from 08 to the bar body 20 correspond to the dimensions from the upper end of the frame 34 to the bar insertion opening 36. When the upper end of the frame 34 is in contact with the lower surface of the base 108, the front and rear of the passenger seat 24 The bar main body 20 and the bar insertion port 36 face each other in the direction.

The distance from the base 108 of the guide 106 to the shaft 80 along the height direction of the passenger seat 24 is as follows:
When the child seat 30 is mounted on the passenger seat 24, the size of the frame 34 along the height direction of the passenger seat 24 is slightly larger.

Further, the rear end of the base 108 is curved downward. This curved portion is formed at a position where the tip of the frame 34 does not interfere even when the bar main body 20 is inserted into the bottom of the bar insertion opening 36 of the frame 34, and between the base 108 and the support 72. The hook 54 is curved at a porosity that allows the hook 54 that has entered the pipe to smoothly be guided downward.

<Operation and Effect of the Present Embodiment> Next, the operation and effect of the present child seat detecting apparatus 10 will be described with respect to the case where the present invention is applied to the connector type connecting device 32 and the case where the present invention is applied to the connector type connecting device 52. And will be described separately.

(In the case of the connector type connecting device 32) FIG.
As shown in FIG. 2, when the child seat 30 employing the connector type connecting device 32 is mounted on the passenger seat 24, the child seat 30 is first arranged on the front side of the seat back 28 of the passenger seat 24, and the frame 34 Are inserted between the side walls 110 and 112 of the guide 106 and between the base 108 and the support 72. In this state, when the child seat 30 is slid toward the rear side of the passenger seat 24 in the mounting direction while guiding the frame 34 to the side walls 110 and 112 and the base 108, the bar main body 20 enters the bar insertion port 36, and When the child seat 30 is further moved substantially toward the vehicle rear side in this state, the bar main body 20 comes into contact with the contact piece 42 of the striker 38, and the bar main body 20 presses the contact piece 42 substantially toward the vehicle front side. When the striker 38 rotates by a predetermined angle in response to this pressing force, the balance of the urging force of the urging means for urging the striker 38 is broken, and the urging means rotates the striker 38. As a result, the lock piece 40 of the striker 38 is positioned substantially rearward of the bar main body 20 with respect to the vehicle, so that the bar main body 20 is prevented from coming off from the bar insertion opening 36 (that is, the child seat 30 is mounted).

As described above, in the present embodiment, as described above, the guide 34 guides the frame 34 so that the bar body 20 can be easily inserted into the bar insertion opening 3 of the frame 34.
6 can be brought into the mounted state of the child seat 30.

Further, as described above, since the swinging wings 82 are in contact with the bar main body 20 in the initial position, the tip of the frame 34 contacts the swinging wings 82 when entering the bar insertion opening 36. Then, the oscillating wing 82 is pressed against the urging force of the torsion coil spring 84 and turned. Swinging feather 8
By this turning, the tip end side in the turning radial direction approaches the flat plate portion (portion between the side wall 74 and the side wall 76) of the support 72 by this turning. As described above, the magnetic sensor unit 90 is disposed on the support body 72, and the oscillating wings 82, at least a part of which is formed of a magnetic material, approach the magnetic sensor unit 90, and the magnetic field formed by the magnet 92. Changes, and the magnetic field crossing the magnetoresistive element 94 changes accordingly. A change in the current value of the current flowing through the circuit accompanying a change in the electric resistance value of the magnetoresistive element 94 is detected by the computer 96, and the computer 96 that has detected the change in the current value changes the resistance value of the magnetoresistive element 94. That is, it is determined that the child seat 30 is attached, and a start / stop signal is sent to the starter 100. As a result, the airbag device 98 is not activated when the child seat 30 is mounted on the passenger seat 24.

(In the case of the hook type connecting device 52)
As shown in FIG. 2, when attaching the child seat 30 employing the hook type connecting device 52 to the passenger seat 24, the hook main body 56 is brought into contact with the lower surface of the base 108 of the guide 106 while the Move to the rear side.
As a result, first, the hook body 56 passes above the bar body 20, but when the hook body 56 moves a predetermined distance behind the passenger seat 24, the hook body 56 reaches the curved portion of the base 108, and when further moved along the base 108, the hook body 56 naturally The hook body 56 moves downward, and the lock piece 60 contacts the bar body 20.

In this state, when the hook body 56 is further moved downward along the base 108, the lock piece 60 turns against the urging force due to the pressing reaction force from the bar body 20, and the hook formed thereby is formed. The bar body 20 enters the inside of the hook body 56 from the gap between the body 56 and the lock piece 60. Further, the lock piece 60 is displaced with respect to the bar main body 20 in a state where the bar main body 20 enters the inside of the hook main body 56 (that is, the hook main body 56 is moved) so that the bar main body 20 and the lock piece 60 come into contact with each other. When the state is released, the space between the tip of the lock piece 60 and the tip of the hook body 56 is closed. In this state, the bar body 20 does not come out of the loop formed by the hook body 56 and the lock piece 60. Absent. In this state, the hook body 56 and the child seat 3
The child seat 30 is mounted on the passenger seat 24 by pulling the base end of the belt 58 connecting the child seat 0 and the child seat 30 and the hook body 56 appropriately.

As described above, in this embodiment, as described above, the guide main body guides the hook main body 56 so that the bar main body 20 can easily enter the hook main body 56 to bring the child seat 30 into the mounted state. be able to.

As described above, since the swinging wings 82 are in contact with the bar main body 20 at the initial position, the base 1
When the hook body 56 is guided by the curved portion 08 and descends, the hook body 56 comes into contact with the swinging wings 82 and presses the swinging wings 82 against the biasing force of the torsion coil spring 84 to turn. Let it. Due to this rotation, the swinging wing 82 has its tip end in the turning radial direction at the flat plate portion (the side wall 74 and the side wall 7) of the support 72.
6). The magnetic sensor unit 90 is disposed on the support 72 as described above. The swinging wings 82, at least a part of which is formed of a magnetic material, approach the magnetic sensor unit 90, so that the magnet 9
2, the magnetic field formed by the magnetic resistance element 9 changes.
The magnetic field across 4 also changes.

The change in the current value of the current flowing through the circuit accompanying the change in the electric resistance value of the magnetoresistive element 94 is determined by the computer 96.
The computer 96 that has detected the change in the current value determines that the resistance value of the magnetoresistive element 94 has changed, that is, determines that the child seat 30 has been mounted,
An activation stop signal is sent to the activation device 100. As a result, the airbag device 98 is not activated when the child seat 30 is mounted on the passenger seat 24.

Here, the above-described operation can be performed without setting the axial direction of the shaft 80 to the left-right direction of the passenger seat 24, for example, the height direction of the passenger seat 24 as the axial direction of the shaft 80. It is. However, in the case where each member on the passenger seat 24 side such as the lock bar 14 described above is provided between the seat back 28 and the seat cushion 26, the seat along the vertical direction of the passenger seat 24 is provided. The gap between the back 28 and the seat cushion 26 is extremely small. For example, when considering the provision of the swinging wings 82 in such a configuration with the height direction of the passenger seat 24 as the axial direction, the swinging wings 82 The length in the direction of the pivot axis becomes extremely small, and the strength of the swinging blade 82 becomes small. On the other hand, when the axial direction of the turning axis of the swinging blade 82 is set to the left and right direction of the passenger seat 24, the length of the swinging blade 82 in the turning axis direction can be sufficiently secured, and the strength of the swinging blade 82 can be ensured. .
