Description

TECHNICAL FIELD The present invention relates to a belt reacher device for an automobile.

2. Description of the Related Art As a seat belt for a front seat of a vehicle, a belt guide for guiding the webbing is provided in a center pillar of the vehicle body. In this position, it may be difficult to take webbing. Especially in a two-door type vehicle, the front door is often located in front of the center pillar because the door opening is wide so as to improve the getting on and off of the rear seat. Therefore, the distance from the front seat to the belt guide is large. Will have to grow. For this reason, when an occupant seated on the front seat wears the seat belt, he or she must twist the body largely backward to take the webbing and pull it.

In order to eliminate the above problems, the reacher arm is rotatably supported by the center pillar, and a belt guide is provided at the tip of the reacher arm.When the seat occupant of the front seat wears the seat belt, the reacher arm is rotated. A belt reacher device has been already put into practical use in which the belt guide is moved forward so that the webbing hung on the guide can be easily taken out. When a person opens or closes the door and moves in or out of the vehicle, the reacher arm is rotated to a position that does not interfere with it.

However, in the above-mentioned conventional belt reacher device, the reacher arm must be manually rotated each time, so that the operation is very troublesome.

Therefore, the movement of opening and closing the door is used to rotate the reacher arm so that when the door is closed, the reacher arm is in the use position, and when the door is opened, the arm is in the storage position. A configured belt reacher device has been proposed. According to this device, since it is not necessary to manually move the reacher arm, no special operation is required, which is very convenient.

However, in the belt reacher device of the above type that has been conventionally proposed, when the door is closed and the reacher arm is brought to the use position, the arm is fixed immovably, so that the reacher arm becomes an obstacle for some reason. Even in such cases, I cannot move this. Further, if the reacher arm is immovable, the seated person wearing the seat belt may feel a little cramped.

The present invention is based on the above-mentioned novel recognition, and an object of the present invention is to provide a belt reacher device capable of rotating a reacher arm even when a seat belt is worn. is there.

In order to achieve the above object, the present invention provides a pivot pin fixed to a center pillar of a vehicle body, a reacher arm having a belt guide on the tip end side, and a basal end side rotatably supported by the pivot pin. The pivot plate rotatably supported by the pivot pin, the spring for biasing the reacher arm and the pivot plate in the direction in which the reacher arm and the pivot plate expand each other, and the angle formed by the reacher arm and the pivot plate is larger than a predetermined angle. In the direction in which the angle formed by the reacher arm and the rotating plate is less than or equal to a predetermined angle, the angle that allows the reacher arm and the rotating plate to rotate relatively around the pivot pin. It is rotatably supported by the vehicle body so as to be pressed by the restricting means and the open chain of the door to rotate from the initial position to the operating position and released by opening the door. A pressed member, a spring for urging the pressed member toward its initial position, and a transmission member connected to the pressed member and the rotating plate, the transmission member comprising:
When the pressed member is in the initial position, the belt guide occupies the storage position behind the door opening, and when the pressed member is pressed by the door to the operating position, the belt guide is used in front of the storage position. We propose a belt reacher device for an automobile, characterized by transmitting the movement of a pressed member to a rotating plate so as to occupy a position.

In addition to the above configuration, when an external force is applied to the reacher arm in a direction in which the belt guide is lifted upward from the use position while the pressed member is stationary in the operating position, the arm rotates as described above. It is particularly advantageous if the transmission member is fitted in an elongated hole formed in the pressed member so that it can be rotated together with the plate.

Effect According to the first configuration, when the door is closed, the member to be pressed is pressed by the door, the movement is transmitted to the rotating plate via the transmission member, and the plate is rotated forward together with the reacher arm. , The belt guide is brought to the use position. At this time, when an external force is applied to the reacher arm in the direction in which the belt guide is lowered, the arm pivots around the pivot pin. When the door is opened, the pressing action on the pressed member is released and the belt guide is returned to the storage position.

According to the second configuration, even when the belt guide is in the use position, when an external force is applied to the reacher arm in the direction in which the belt guide is lifted, the arm can rotate as it is.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing a state in which a front seat on a driver's side is viewed from the inside of a two-door type automobile, and 1 is a vehicle body 10
0 is a center pillar, 2 is a door arranged in a door opening 3 in front of the center pillar, and 4 is a front seat. FIG. 2 is a view similar to FIG. 1 when the door 2 is opened. A garnish 8 is provided on the inner side surface of the center pillar 1 as shown in FIG.

A seatbelt webbing 9 is attached to the body of an occupant seated on the seat 4, and the webbing 9 extends upward from a seatbelt retractor 6 arranged in the internal space of a side portion structure of the vehicle body and extends from an opening 7 to the vehicle. After coming out inside, it is slidably hung on a belt guide 10 to be described later, and is locked to a mooring portion 106 at the lower part of the vehicle body.

FIG. 2 shows a state in which the seat belt is not worn. In order to wear the belt from this state, an occupant seated on the seat 4 pulls the webbing 9 and wears the belt as shown in FIG. The tongue plate 11 slidably provided in the middle part of the webbing is locked to the buckle 12 attached to the center part of the vehicle.

By the way, in the two-door type vehicle as shown in FIGS. 1 and 2, the door opening 3 is formed large so as to enhance the getting on and off the rear seat (not shown), as described above, and therefore the front opening. Seat 4 is center pillar 1
Often located in front of. Therefore, assuming that the above-mentioned belt guide 10 is directly attached to the center pillar 1, when the occupant seated on the front seat 4 wears the seat belt, the webbing 9 hung on the belt guide 10 reaches his / her body. Difficult to draw, and its operability deteriorates. In order to eliminate such a problem, the belt reacher device 13 according to the present invention is provided. The details will be clarified below.

As shown in FIGS. 3 to 5, a pivot pin 14 is fixed to the vehicle inner panel 1a of the center pillar 1, and the reacher arm 15 and the base end side of the rotary plate 16 are rotatable on the pin 14, respectively. It is supported. The belt guide 10 is rotatably attached to the tip end side of the reacher arm 15, and the webbing 9 is hung on the guide 10. As can be seen from FIG. 3, the reacher arm 15 is located inside the garnish 8 and the rotating plate 16 is located outside the garnish 8, and the pivot pin 14 is located inside the car. , Cover 18 locked to garnish 18
(Not shown in FIGS. 4 and 5).

As shown in FIGS. 3 and 5, a first torsion coil spring 17 is wound around the pivot pin 14, each end of which is locked to the rotating plate 16 and the reacher arm 15, respectively. The plate 16 and the arm 15 are urged by the spring 17 in the directions in which they expand and expand as shown by an arrow A in FIGS. 4 (a) and 4 (b).

A second torsion coil spring 19 is wound around the pivot pin 14, and each end of the second torsion coil spring 19 is locked to the vehicle inner panel 1a of the center pillar 1 and the rotating plate 16, and is rotated by the spring 19. The plate 16 is biased in the direction indicated by arrow B in FIGS. 4 (a) and 4 (b).

An arcuate elongated hole 20 centering on the pivot pin 14 is formed in the rotating plate 16, and a projection piece attached to the reacher arm 15.
21 plunges into the long hole 20. At this time, the rotating plate 16
And the reacher arm 15 are urged by the first torsion coil spring 17 so as to open and expand each other,
As shown in FIGS. 4A and 4B, 21 is pressed against one end of the elongated hole 20 to prevent the angle formed by the arm 15 and the plate 16 from becoming larger than a predetermined angle θ. However, the reacher arm 15 and the rotating plate 16 can rotate in a direction in which the angle between them is less than or equal to the angle θ. As described above, in this example, the elongated hole 20 formed in the rotating plate 16 and the projecting piece 21 attached to the reacher arm 15 are provided.
In the direction in which the angle formed by the reacher arm and the rotating plate is prevented from becoming larger than a predetermined angle, and the angle formed by the reacher arm and the rotating plate becomes less than or equal to the predetermined angle, the reacher arm and the rotating plate are An angle restriction means is configured to permit relative rotation around the pivot pin.

On the other hand, a pressed member 22 is rotatably supported on the vehicle body portion below the door opening as shown in FIGS. 6 and 7. In the illustrated example, the bracket 2 fixed to the vehicle body 100
The shaft portion 24 of the pressed member 22 is rotatably supported in the center hole of 3, and the outer lever 25 is integrally attached to the vehicle outer end of the shaft portion 24 and the inner lever 26 is integrally attached to the inner end thereof. Has been done.

The tip of the outer lever 25 projects into the rotation locus of the door 2 that is opened and closed. When the door 2 is open, the pressed member 22 is pushed by the pressed member 22 shown in FIGS. Although it occupies the initial position shown by the solid line in the figure, when the door 2 is closed,
As shown by the chain line in FIG. 6, the outer lever 25 is pressed by the door 2 and pivots to the operating position shown in FIG. 4 (b).

A third torsion coil spring 27 is wound around the shaft portion 24 of the pressed member 22 as shown in FIG. 6, and its ends are locked to the vehicle body and the pressed member 22. Pressing member 22
Is always biased counterclockwise in FIG. Therefore, when the pressing action applied to the pressed member 22 is released by the opening of the door 2, the member 22 is moved to the position shown in FIGS.
The spring 27 returns to the initial position shown in FIG.
At this time, the movement of the pressed member 22 is restricted by a stopper (not shown) so as not to rotate outside the range between the initial position and the operating position.

The pressed member 22 and the rotating plate 16 are connected to the upper and lower ends of a transmission member including a rod 28 or a wire as shown in the drawing. The bent upper end of the rod 28 is the rotating plate 16
The bent lower end of the rod 28 is slidably fitted in an arc-shaped long hole 29 formed in the inner lever 26 of the pressed member 22. .

Next, the operation of the belt reacher device will be described.

When the door 2 is open as shown by the solid line in FIGS. 2 and 6, the pressed member 22 is shown in FIGS. 3 and 4 (a) and 6 as described above. Occupies an initial position. At this time, the rotating plate 16 urged in the direction of arrow B by the second torsion coil spring 19 acts to lift the rod 28 upward, but the lower end of the rod 28 is the long hole 29 of the pressed member 22. Since it hits the upper end of the rod 28, the rod 28 and the rotating plate 16 stand still in the position shown in FIG. 4 (a).
At that time, since the rotating plate 16 and the reacher arm 15 are biased by the first torsion coil spring 17 in the directions of expanding and expanding each other, the reacher arm 15 also forms a predetermined angle θ with respect to the rotating plate 16. While keeping it, it occupies a position behind the door opening 3 shown in FIG. Therefore, the belt guide 10 attached to the arm 15 is also stationary at the storage position behind the door opening 3.

As described above, when the door 2 is opened, the reacher arm 15 and the belt guide 10 are stored in the retracted position retracted rearward from the door opening 3, so that when the occupant gets in and out of the vehicle, the arm 15 and the webbing 9 are not moved. There is no hindrance.

When an occupant gets into the vehicle, sits on the front seat 4 and closes the door 2, the movement of the member causes the pressed member 22 to move to the fourth position.
It rotates clockwise from the initial position shown in FIG. 4 (a) to the operating position shown in FIG. 4 (b). Therefore, the rod 28 is lowered downward, and the rotating plate 16 is also rotated clockwise from the position shown in FIG. 4 (a) to the position shown in FIG. 4 (b). At that time, the action of the first torsion coil spring 17 causes the reacher arm 15 to integrally rotate together with the rotating plate 16 to move to the position shown in FIGS. 1 and 4B, that is, the door opening 3. Occupy a protruding position. Therefore, the belt guide 10 is also brought to the use position in front of the storage position shown in FIG. That is, the belt guide 10 with the webbing 9 approaches the occupant sitting on the front seat 4. For this reason, the occupant can easily pull the webbing 9 to his / her body while wearing the seat 4 in a comfortable posture and attach the same.

When the door 2 is opened again, each element is shown in FIGS. 3 and 4 (a).
It is natural to return to the state of.

As shown in FIG. 3, the rod 28 penetrates through the panel 1a on the inner side of the vehicle body, but the guide piece 30 made of synthetic resin is fitted therein, and the rod 28 moves up and down inside thereof. The rod 28 can operate smoothly.

As shown in FIG. 4 (b), when the reacher arm 15 maintains a substantially horizontal posture, when an external force F1 that rotates the reacher arm 15 downward is applied to the arm 15, the arm 15
Is pivotally supported by the pivot pin 14, so that it pivots around the pin 14 as it is as shown in FIG. At this time, the protruding piece 21 of the reacher arm 15 is made into the long hole of the rotating plate 16.
Since it moves within the arm 20, the rotation of the arm 15 is not hindered. At this time, the rotating plate 16 remains stationary at the position shown in FIG. 4 (b).

An external force F2 is applied to the reacher arm 15 at the position shown in FIG. 4 (b) in the direction of lifting the belt guide 10 while the door 2 is closed, that is, the pressed member 22 remains stationary at the operating position. Even when the arm 15 is rotated, the arm 15 can rotate together with the rotating plate 6 while maintaining a predetermined angle θ. That is, at this time, the rod 28 operates downward, but since the lower end of the rod 28 can move along the elongated hole 29 of the pressed member 22, even if the pressed member 22 is locked in the operating position, the rod 28 is not locked. Operates without any problems, reacher arm
It is possible for 15 to rotate more freely in the clockwise direction than the position shown in FIG. 4 (b).

When the door 2 is opened and the pressed member is stationary at the initial position, as shown in FIG. 4 (a), even when an external force in the clockwise or counterclockwise direction is applied to the reacher arm 15, It is apparent from the above description that the arm 15 can be rotated substantially freely in either direction.

As described above, since the reacher arm 15 can be rotated even when the seat belt is worn, when the occupant seated on the seat 4 moves the body and applies an external force to the arm 15, the arm 15 can freely rotate. It does not move and does not give the passenger a sense of restraint. Also, since the reacher arm 15 can be rotated, the arm can be rotated by an external force applied to it.
Problems such as deformation of 15 can also be prevented.

Incidentally, the lower end of the rod 28 is pivotally attached to the round hole of the pressed member 22 instead of the elongated hole 29 of the pressed member 22, and the movement of the pressed member 22 is
The second spring 19 can be omitted when it is configured to be directly transmitted to the rotary plate 16 via the rod 28.

Although the belt reacher device for the front seat on the driver's side has been described above, the present invention is naturally applicable to the belt reacher device for the seat on the passenger side.

Effect According to the present invention, since the reacher arm can be operated in conjunction with opening and closing of the door, a special operation such as manually moving the arm is unnecessary. Moreover, the reacher arm can be moved even with the door closed,
The practicality can be further improved.
