Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an automatic seat belt device that automatically attaches webbing to an occupant after the occupant is seated. The present invention relates to a changeable automatic seat belt device.

[Prior Art and Problems to be Solved by the Invention] An automatic seat belt device has been proposed (Utility Model Application No. 55-28552) that can automatically attach or detach webbing to an occupant.

One end of the webbing is wound up by a winding device installed in the center of the vehicle, and the other end of the webbing can be moved in the longitudinal direction of the vehicle by being guided by a guide rail installed near the roof side of the vehicle. The structure is such that the webbing is locked to a slider, and the slider is moved to attach or release the webbing.

In other words, when the slider moves toward the front of the vehicle on the guide rail, a space is created between the middle part of the webbing and the seat, and when the occupant sits on the seat, the slider moves toward the rear of the vehicle on the guide rail. , and the webbing is put on.

The stop position of the slider corresponding to this webbing-attached state is detected by a limit switch and is stopped. In this structure, the limit switch is placed on the rear side of the guide rail of the vehicle, so that the slider is stopped in accordance with a standard-sized passenger. For this reason, when occupants of different physiques ride the vehicle, the webbing attachment position may not be optimal. In order to solve this problem, an automatic seat belt device is known in which the stopping position of the slider on the rear side of the vehicle can be changed, and the webbing can be installed in the optimal state according to the physique of the occupant (Utility Application No. 59-34815). ).

In this automatic seat belt device, the vehicle rear end side of the guide rail is fixed to a fixing member formed by joining two plates and having a housing portion formed inside. On one plate of the fixed member,
A plurality of engagement holes are formed. An operating lever including an engagement pin that is engaged with the engagement hole is movably provided in the housing portion of the fixing member. When the slider is moved from the front side of the vehicle to the rear side of the vehicle, the engagement groove formed in the slider engages with the engagement pin, thereby restricting movement of the slider toward the rear side of the vehicle. There is.

In the automatic seat belt device described above, the stopping position of the slider on the rear side of the vehicle is changed by moving the operating lever to change the engagement hole that engages with the engagement pin.

However, when the slider is on the rear side of the vehicle, even if you try to move the operating lever to change the engagement hole that engages with the engagement pin, the slider is in a position where it will interfere with the operating lever when moving the operating lever. The stop position of the slider on the rear side of the vehicle cannot be changed.

In order to solve this problem, the following automatic seat belt device has been proposed (Utility Application No. 135251/1982).

This automatic seat belt device is provided with a detection means for detecting the stop position of the slider on the rear side of the vehicle and stopping the drive means. Further, one end is connected to the driving means, and a portion between the driving means and the guide rail is housed in a flexible guide member, and the driving force of the driving means is transmitted to the slider, and the slider is moved along the guide rail. A flexible elongated body is provided for causing the Then, the flexible guide member is elastically deformed and the detection means is selectively fixed at a plurality of predetermined positions by the locking means to adjust the stopping position of the slider on the rear side of the vehicle.

However, in the automatic seat belt device described above, when the slider is at the vehicle rear side stop position, the vehicle rear side stop position can be changed, but when the slider is located at the vehicle front position, the slider is at the vehicle rear side stop position. The problem is that the position cannot be adjusted.

That is, when the slider is located at the front position of the vehicle, when the bent flexible guide member is extended, the flexible elongated body also extends and the slider tends to move toward the front of the vehicle. However, since the slider interferes with the detection means for detecting the position of the slider in front of the vehicle and prevents the slider from moving toward the front of the vehicle, it is not possible to adjust the stopping position of the slider on the rear side of the vehicle.

The present invention takes the above facts into consideration and aims to provide an automatic seat belt device that can adjust the slider stop position regardless of the slider stop position.

[Means and effects for solving the problems] The automatic seat belt device according to the present invention is an automatic seat belt device that can automatically attach webbing to an occupant using the driving force of a driving means, and includes: A guide rail disposed near the roof side of the vehicle, a slider to which one end of the webbing is locked and movable guided by the guide rail, and a stopping position of the slider on the rear side of the vehicle at a first position and from the first position. and an adjusting means that can be adjusted to a second position remote from the vehicle front end of the guide rail, and one end of which is connected to the drive means and receives the driving force of the drive means to move along the guide rail in the longitudinal direction of the vehicle. a flexible elongated body that moves and transmits a moving force to the slider; and a flexible elongated body that is disposed between the drive means and the guide rail and accommodates the flexible elongated body so as to be movable in the longitudinal direction of the vehicle, and the adjustment means As a result, the vehicle rear side stopping position of the slider is at the first position.
an elongate body guide cover including a bending portion that is bent together with the flexible elongate body when the position is changed from the first position to the second position; a detected portion located between the bent portion and the driving means when the elongated body guide cover is located; The present invention is characterized in that it includes a detection means that detects the detected portion when the detected portion is located between the bent portion and the drive means due to movement of the flexible elongated body.

In the above automatic seat belt device, when the flexible elongated body is moved forward of the vehicle by the driving means, the detected portion of the flexible elongated body reaches between the bend and the driving means. The detected portion is detected by the detection means. By stopping the driving means at the time of this detection, the slider is positioned at the vehicle front side stop position.

With the slider located at the vehicle front stop position, when the adjusting means adjusts the vehicle rear stop position of the slider to the second position, the bent portion bends together with the flexible elongated body, and the slider moves toward the vehicle rear side. Moving. On the other hand, set the slider to the first stop position on the rear side of the vehicle.
When adjusted to this position, the bend of the bent portion is released and the slider moves toward the front of the vehicle by the amount of this release. In this case, the detection means is located near the outer circumferential surface of the elongated body guide cover between the bending part and the drive means, and is located off the trajectory of movement of the slider toward the front of the vehicle. Adjustment of the stop position of the slider on the rear side of the vehicle can be performed satisfactorily without being hindered by the detection means.

Furthermore, when the slider is located at the vehicle front stop position, when adjusting the vehicle rear side stop position of the slider, the bending part is only bent and released, and the positional relationship between the detected part and the detection means is changed. Since there is no change, the detection state of the detected portion by the detection means is maintained, and the driving means is set in a non-driving state.

Furthermore, when the slider is positioned at the vehicle rear stopping position and the adjustment means is used to adjust the vehicle rear stopping position of the slider, the bending portion and the flexible elongated body are bent and extended, so that a load is applied to the driving means. It doesn't cost anything.

[Embodiment] FIG. 1 shows an automatic seat belt device 10 according to this embodiment.

A guide rail 16 is installed on a roof side rail (not shown) on the roof side 14 of the vehicle 12.

The leading end of the guide rail 16 extends along the front pillar 18 of the vehicle 12, and the rear end of the guide rail 16 is bent approximately at right angles along the center pillar 20.

As shown in FIG. 2, this guide rail 16
A groove 22 is provided on the surface facing downward of the vehicle, a slider 24 is inserted into this groove 22, and a webbing 27 (first
(see figure) is locked at one end.

The other end of the webbing 27 is connected to a winding device 28 disposed in the center of the vehicle, as shown in FIG.
It is rolled up and stored in layers. This winding device 28 is fixed to the vehicle body inside a center console 29.

The take-up device 28 has a built-in inertia lock mechanism that senses this with an acceleration sensor in the event of a vehicle emergency and instantly prevents the webbing 27 from being pulled out.

As also shown in FIG. 3, the inside of the groove 22 of the guide rail 16 is widened to accommodate a head 30 formed at the end of the slider 24. As shown in FIG. Also, groove 2
A wire accommodating groove 32 is formed at the bottom of 2, and a long wire rope 34 is disposed therein.

As shown in FIG. 3, this wire rope 34
Two rings 36 and 37 are fitted and locked at a predetermined interval (Dimension W in FIG. 3) at the tip of the wire rope 34 between them, and the lost motion connector 3 is connected to the wire rope 34 between them.
8 are slidably fitted.

The lost motion connector 38 is connected to the slider 2
A protrusion 40 is formed extending in four directions.
It is housed in a recess 42 provided in the head 30 of the slider 24 .

The rear end of the wire rope 34 is connected to the guide rail 1
The guide cube 4 extends along the wire receiving groove 32 of No. 6 and is installed at the rear end of the guide rail 16.
3 (see FIG. 1) and is wound onto the take-up reel of the drive means 41.

As a result, when the driving means 41 rotates in the normal direction, a compressive force is generated in the wire rope 34 within the guide cube 43, and the wire rope 34 moves toward the front side of the vehicle along the wire receiving groove 32.

Furthermore, if the drive means 41 is reversed, a tensile force is generated within the guide tube 43 and the wire rope 3
4 to the rear of the vehicle.

Here, the lost motion connector 38 attached to the wire rope 34 is moved by being pressed by the ring 36 or the ring 37. That is, when the wire rope 34 is moved toward the front of the vehicle, the ring 37 on the rear side of the vehicle presses the slider 24, and when the wire rope 34 is moved toward the rear of the vehicle, the ring 37 on the front side of the vehicle is pressed. 3
6 to press the slider 24.
When the slider 24 starts moving, the wire rope 34 is moved by the distance between the rings 36 and 37 (Dimension W in Figure 3).
There is a slight delay from the start of movement.

Here, when the slider 24 is moved to the vehicle front end of the guide rail 16, a space is created between the webbing 27 and the seat 44 (first
(see imaginary lines), the occupant 46 can easily sit on the seat 44.

Furthermore, when the slider 24 is moved to the vehicle rear end of the guide rail 16 in this state, the occupant 46
is in the webbing device state.

3 and 4 show the slider 24 being moved to the rear end of the guide rail 16. As shown in FIGS.

A reinforcement 48, which is a receiving member, is fitted to the outer periphery of the rear end of the guide rail 16. Reinforcement 48 is circular hole 5
It is attached to the vehicle body via a bolt inserted through 2. As a result, if the vehicle falls into an emergency state with the slider 24 in the webbing attachment position, the load applied to the slider 24 can be reliably transmitted to the vehicle body via this reinforcement 48. .

A plurality of circular holes 50 are provided in this reinforcement 48 along the longitudinal direction of the guide rail 16.

Further, a holder 54 is fitted to the outer periphery of the reinforcement 48. This holder 54 is made of resin and has a substantially U-shape with leg plates 56 and 58 that are parallel to each other, and is configured so that it can come into contact with the outer periphery of the reinforcement 48 and slide in the direction of arrow E in FIG. It's summery.

Protrusions 60 and 62 are formed at the tips of the leg plates 56 and 58, respectively, and circular holes 64 are coaxially provided in the protrusions 60 and 62, respectively.

A pin 66 is spanned through the circular hole 64, and a pole 68 is pivotally supported by this pin 66. paul 68
is formed in a substantially U-shape, and a claw portion 70 is formed in a portion thereof, and is adapted to correspond to a recessed portion 72 formed in the slider 24.

Further, a torsion coil spring 67 is attached to the pin 66 that pivotally supports the pole 68.
The pawl 68 is urged so that the claw portion 70 rotates about the center point 6 in the direction in which the claw portion 70 enters the recess 72 (in the direction of arrow A in FIG. 3). While the claw portion 70 is inserted into the recess 72, the slider 24 is prevented from moving along the guide rail 16 in the forward direction of the vehicle.

A circular hole 74 is provided in the leg plate 58 of the holder 54, and this circular hole 74 is adapted to correspond to the circular hole 50 of the reinforcement 48 by sliding the holder 54.

A lock pin 76 serving as an adjusting means is provided in the circular hole 74.
A large-diameter portion 78 formed at one end is passed through. The other end of the lock pin 76 is threaded into the knob 82 after its middle portion passes through the tension holder 80. Note that a compression coil spring 84 is provided between the tension holder 80 and the large diameter portion 78.
is interposed to urge the lock pin 76 in the direction of arrow B in FIG.

Therefore, when the holder 54 is selectively placed in a position where the circular hole 74 is coaxial with the circular hole 50, the lock pin 76 also passes through the circular hole 50, thereby preventing the holder 54 from moving. Further, by pulling the knob 82 in the direction opposite to the direction of arrow B in FIG. 3 against the biasing force of the compression coil spring 84, the lock pin 76 comes out of the circular hole 50 and the holder 54 becomes slidable.

The tension holder 80 is attached to the holder 54 via a screw 81 and is extended downwardly of the vehicle, with its tip end connected to the wire guide tube 4.
It is fixed to the upper end of the vehicle No. 3. Therefore, when the tension holder 80 moves with the movement of the holder 54, the guide cube 43 also moves.

Here, the guide cube 43 is straight (see FIG. 1) with the locking pin 76 disposed in the circular hole 50 in the upper part of the reinforcement 48. Therefore, when the tension holder 80 moves downward in the vehicle, the guide cube 43 is bent into an arched shape (see the imaginary line in FIG. 1).

That is, the lost motion connector 38 can be moved without changing the amount of wire rope 34 pulled out from the take-up reel of the drive means 41, and the slider 24 is also moved accordingly.

This wire rope 34 has a lost motion piece 86 further to the rear of the vehicle than the ring 37.
is fitted and locked and corresponds to the lost motion lever 88. The lost motion lever 88 is pivotally supported by the holder 54 together with a limit switch 92 via a pin 90.

A narrow two-pronged extension portion 94 extending toward the pole 68 is integrally formed on the lost motion lever 88 . The tip of this extension 94 is brought into contact with the pole 68 so that the claw 70 of the pole 68 is sandwiched therebetween. Here, when the lost motion lever 88 rotates about the pin 90 in the direction of arrow C in FIG. It is designed to press in the direction of

Lost motion lever 88 is wire rope 3
4 rotates by interfering with the lost motion piece 86 when moving toward the front of the vehicle.

The first limit switch 92 has its contact 9
2A corresponds to the protrusion 96A of the push dog 96 which is slidably fitted into the groove 22 of the guide rail 16. The contactor 92A is adapted to move upward of the vehicle (in the direction of arrow D in FIG. 3) by the urging force of an unillustrated urging means.

Although the push dog 96 presses the contact 92A with its own weight, it does not have enough weight to push down the contact 92A. Further, the push dog 96 can be omitted if a portion corresponding to the protrusion 96A can be provided on the slider 24.

Here, when the slider 24 moves toward the rear of the vehicle, its head 30 pushes down the push dog 96, and the protrusion 96A pushes down the contact 92A to stop the driving force of the drive means 41.

As shown in FIG. 4, the interference of the lost motion piece 86 with the lost motion lever 88 and the pressing movement of the slider 24 by the lost motion connector 38 are synchronized.

That is, at the time when the wire rope 34 starts moving in the forward direction of the vehicle, the ring 36 and the lost motion connector 38 are in contact with each other (see the solid line in FIG. 4), and the lost motion connector 3
8 is pressed by the ring 37, the lost motion piece 86 rotates the lost motion lever 88. (See the broken line in Figure 4).

Therefore, when the slider 24 starts moving by the lost motion connector 38, the claw portion 70 closes in the recess 7.
2 so as not to affect the movement of the slider 24.

As shown in FIGS. 5 and 6, a cutout window 43A is provided at the vehicle rear end of the guide cube 43. The wire rope 34 moving within the guide cube 43 is exposed from this cutout window 43A. A second limit switch 100, which is a detection means, is attached to the drive means 41 in correspondence with the notched window 43A. The second limit switch 100 is equipped with a contactor 100A, and is biased in a direction approaching the wire rope 34. Therefore, the contact 100A passes through the cutout window 43A and comes into contact with the wire rope 34.

On the other hand, the wire rope 34 is provided with a reduced diameter portion 34A, and when the slider 24 is moved to the stop position on the front side of the vehicle, this reduced diameter portion 34A comes to correspond to the cutout window 43A. There is. When the reduced diameter portion 34A corresponds to the notch window 43A, the contact 10 of the second limit switch 100
0A comes into contact with this reduced diameter portion 34A and is swung counterclockwise to the position shown by the solid line in FIG. This allows the second limit switch 100 to detect the arrival of the slider 24 at the vehicle front side stop position and send a signal to the control circuit.

In addition, when the adjustment position of the holder 54 is located downward, the wire rope 34 is connected to the guide cube 43.
At the same time, it is bent into an arcuate shape between the drive means 41 and the tension holder 80, and is bent. When adjusting the holder 54 from below to above, the slider is moved forward of the vehicle by the amount of deflection of the wire rope 34. Therefore, since the reduced diameter portion 34A with which the contactor 100A is in contact does not move, the vehicle rear side stopping position of the slider 24 can be adjusted while the drive means 41 is not driven.

The operation of this embodiment will be explained below.

When the passenger 46 gets on the vehicle, the slider 24 is moved to the vehicle front end of the guide rail 16, and in this state, the second limit switch 10
Since the zero contact 100A is in contact with the reduced diameter portion 34A, the driving means 41 is in a non-driving state. Therefore, a space is created between the webbing 27 and the sheet 44. Thereby, the occupant 46 can easily sit on the seat 44.

When the occupant 46 is seated on the seat, the driving means driving means 41 is reversely rotated to generate a tensile force on the wire rope 34, and the ring 36 presses the lost motion connector 38 to move the slider 24 along the guide rail 16 to the rear of the vehicle. move it to the side.

When the wire rope 34 moves, the lost motion piece 86 first comes into contact with the lost motion lever 88, and the lost motion lever 88 is rotated counterclockwise in FIG. 3 (in the direction of arrow C in FIG. 3). let

This rotation of the lost motion lever 88 causes the extension 94 to rotate the pawl 68 about the pin 66 in a direction opposite to the direction of arrow A in FIG. 3 against the biasing force of the torsion coil spring 67.

While this state is maintained, the tip of the head 30 of the slider 24 passes through the pole 68 without interfering with it.

A holder 54 is disposed at the vehicle rear end of the guide rail 16, and the holder 54 is fixed by a lock pin 76 fitted into a predetermined circular hole 50.

This holder 54 has a first limit switch 9.
2 is attached, and when the slider 24 moves, the end of the head 30 of the slider 24 comes into contact with the push dog 96, and the slider 24 moves.
The protrusion 96A pushes down the contact 92A of the first limit switch 92 and stops the driving means 41. This puts the occupant 46 in the webbing wearing state.

Here, the lost motion piece 86 is separated from the lost motion lever 88, and the pressing of the pole 68 by the lost motion lever 88 is released.

As a result, the pole 68 is connected to the torsion coil spring 6.
7 rotates about the pin 66 in the direction of arrow A in FIG. 3, and the claw portion 70 enters the recess 72 of the slider 24.

Here, if the vehicle falls into an emergency state, the acceleration sensor senses this and the inertia lock mechanism is activated to instantly prevent the webbing 27 from being pulled out from the take-up device 28.

Thereby, the occupant 46 can be placed in a restrained state. In this case, a load is applied to the slider 24 via the webbing 27 due to the inertial force of the occupant 46, but this load can be reliably transmitted from the head 30 of the slider 24 to the vehicle body via the reinforcement 48. .

Note that even if the vehicle overturns and a load is applied that causes the slider 24 to move toward the front of the vehicle along the guide rail 16, the claw portion 70 of the pawl 68 enters the recess 72 of the slider 24, so that the slider 24 24 does not move, and this load can be reliably transmitted to the vehicle body.

Further, when an occupant of a different physique rides in the vehicle, the lock pin 76 can be inserted into another circular hole 50 to change the stopping position of the slider 24 according to the physique of the occupant.

To do this, first, the knob 82 is pulled up against the biasing force of the compression coil spring 84 (in the opposite direction to the direction of arrow B in FIG. 3).

This action causes the lock pin 76 to separate from the circular hole 50. Thereby, the holder 54 is made slidable, and the lock pin 76 can be easily adapted to the other circular hole 50.

When the knob 82 is released with the lock pin 76 and the circular hole 50 corresponding to each other, the lock pin 7
6 is inserted into the circular hole 50, and the holder 54 is fixed.

Further, since the guide cube 43 is bent from a straight state to an arched shape or vice versa together with the tension holder 80, the wire rope 34 from the take-up reel of the drive means 41 to the lost motion connector 38
can be moved without changing its actual length.

The aforementioned operation of changing the stop position of the slider 24 is possible even when the slider 24 is at either the forward limit or the backward limit stop position.

That is, when the slider 24 is at the backward limit, the reason is as follows. When the holder 54 is moved, the tension holder 80 is also moved together with the holder 54, and the shape of the guide cube 43 is changed as described above. This is because the positional relationship between the wire rope 34 and the lost motion connector 38 is not changed.

Further, when the slider 24 is at the forward limit, the reason is as follows. When the holder 54 is moved from the lower position to the upper position, the wire rope 34 is moved toward the front of the vehicle, and the slider 24 is similarly moved by the compressive force of the wire rope 34. At this time,
The second limit switch 100 is the wire rope 3
This is because the slider 24 is disposed along the line 4 and does not hinder the movement of the slider 24. In the conventional arrangement of the limit switch, the limit switch is provided on the extension of the movement locus of the slider 24 and obstructs the movement of the slider 24, so there is no place for the wire rope 34 to escape, and the slider 24 is at the forward limit stop position. In some cases, it has been impossible to move the holder 54 from below to above.

The operation of changing the stop position of the slider 24 at its backward limit when the slider 24 is at its forward limit stop position will be described in detail below.

First, a case will be described in which the holder 54 is moved from the bottom to the top to raise the retracting limit stop position of the slider 24. In this case, the slider 24 is stopped at the vehicle front side stop position before the movement operation of the holder 54 is started. In this state, the contact 100A of the second limit switch 100
corresponds to the reduced diameter portion 34A of the wire rope 34, and the driving means 41 is in a non-driving state. In this state, the wire rope 34 is connected to the guide tube 43, the drive means 41, and the tension holder 80.
It is bent into an arched shape between the two and is bent.

When the movement of the holder 54 is started, the wire rope 34 changes from a bent state to a substantially straight state, and the slider 24 is moved toward the front of the vehicle in accordance with this changed amount. At this time, the reduced diameter portion 34A with which the contactor 100A abuts does not move, so the driving means 41 continues to maintain its non-driving state.

Next, a case will be described in which the holder 54 is moved from above to below to lower the retracting limit stop position of the slider 24. Also in this case, the slider 24 is stopped at the vehicle front side stop position before the movement operation of the holder 54 is started. In this state, the contact 100A of the second limit switch 100 corresponds to the reduced diameter portion 34A of the wire rope 34,
The driving means 41 is in a non-driving state. Also, in this state, the wire rope 34 is connected to the guide cube 43.
Both are in a substantially straight line state. When the movement of the holder 54 is started, the guide cube 43 is bent into an arch shape together with the wire rope 34, and the slider 24 is moved toward the rear of the vehicle. At this time as well, the reduced diameter portion 34A that the contact 100A abuts does not move, so the driving means 41 continues to maintain its non-driving state.

In this way, the slider 24 can be adjusted according to the physique of the occupant.
Since the stopping position on the rear side of the vehicle can be changed regardless of the stopping position of the slider 24, it is possible to conveniently obtain the optimal webbing wearing state for occupants of a wide range of physiques.

In this case, in the event of a vehicle emergency, no load is directly applied to the holder 54, and the holder 54 can be made of relatively lightweight resin, making it easier to operate. The ease of this operation is
Since the holder 54 can be moved without applying any load to the wire rope 34, the light adjustment force is also a major factor.

Next, when the vehicle finishes traveling and the passenger 46 exits the vehicle, the slider 24 moves toward the guide rail 16.
is moved to the front end of the vehicle.

To explain this operation, first, the driving means 41 starts normal rotation, and a compressive force is applied to the wire rope 34 within the guide cube 43.

As a result, the wire rope 34 starts moving toward the front of the vehicle along the guide rail 16.

Here, in the slider 24, the lost motion piece 86 that moves together with the wire rope 34 comes into contact with the lost motion lever 88, and the lost motion lever 88 causes the claw portion 70 of the pole 68 to
is separated from the recess 72.

This is done until the ring 37 comes into contact with the lost motion connector 38, and the dimension W
(See FIG. 3) The start of movement of the slider 24 is slightly delayed. In this way, since the engagement between the claw portion 70 and the recess 72 can be automatically released, the complexity of the operation can be reduced.

In the present invention, the wire rope 34 is used as the elongated body, but a flexible thin tape may also be used.

Further, a second limit switch 100 for detecting the stop position of the slider 24 in front of the vehicle is connected to the driving means 41 in correspondence with the intermediate portion of the wire rope 34 on the rear side of the vehicle.
Since the guide rail 16 is attached to the front side of the vehicle, the discomfort caused during transportation and assembly, which is caused by the conventional limit switch and cord attached to the front side of the vehicle, is reduced.

[Effect of the invention] With the above configuration, according to the invention,
This provides an excellent effect in that the stop position of the slider on the rear side of the vehicle can be adjusted regardless of the stop position of the slider.
