Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a passive seat belt device incorporated into a vehicle.

Conventional passive seat belt mounting is, for example, a three-point seat belt as shown in FIG.
A first seat belt 5 is also fixed to the rear of the side lou frame 60 via a retractor through a through ring 52 that moves back and forth on a guide rail 58 provided in the seat belt 5, and
One end is fixed to the rear lower part of the door 2 via a retractor 42, and the other end is fixed to the middle of the first seat belt 5 through a through ring 50 that moves back and forth on a guide rail 62 provided on the door 2. 2. The motor 40 is driven by the operation of the seat belt 11, the door switch 54, the motor 40 provided at the front of the vehicle body 1, and the door switch 54.
The through ring 50. is driven by the through ring 50. One end that moves the through ring 50. 52 and the other end of which is connected to the motor via a roller 57.
The structure consists of 48.

As described above, the conventional passive seat belt device uses a motor as a driving means for restraining and releasing an occupant by the seat belt, but has the drawbacks of being expensive and having a complicated structure.

The present invention has been developed in view of the above-mentioned drawbacks, and the driving means for restraining and releasing the occupant by the seat belt is performed by an extremely simple actuating device that is linked to the opening/closing operation of the door.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 1 denotes a car body, and doors 2 are screwed to both sides of the car body 1 so that they can be opened and closed. It is provided.

Further, the tip portion 5 of the first seat belt 5 of the retractor 4
A through ring 6 is energized at the through ring 6, and a second seat belt 11, which will be described later, is passed through a slot 6a of the through ring 6.

Furthermore, a Shonoredder anchor 7 and a wrap-out anchor 8 are attached to the rear upper and lower parts 2a and 2b of the door 2 by respective pin shafts 9 and 10, and the Shonoredder anchor 7 and the up-out anchor 8 A second seat belt 11 is provided between the two and connected to each other by passing through the hole 6a of the through tongue 6.

On the other hand, the door 2 at a position close to the wrap-out anchor 8 is provided with an elongated hole 12 extending upward and downward, and a pair of bearing brackets are provided near both edges of the hole 12 inside the door 2. A rotating shaft 15 is rotatably mounted on each bearing bracket L-14, 14, and an arm rod with a ring is mounted on the rotating shaft 15 where the strip hole 12 is located. The base 16a of 16 is rigid and mounted on a shaft.

As a result, the arm rod 16 with a ring is freely rotatable in the vertical direction.

An elongated ring 16b attached to the free end of the ring arm rod 16 extends upward from the slot 12, and the second seat belt 11 is passed through the ring 16b.

Furthermore, a spring 17 is provided between the base 16a of the arm rod 16 with a ring and the bearing bracket 14 adjacent thereto, so as to apply a biasing force to the arm rod 16 with a ring toward the inside of the door 1. It is wrapped.

However, the upper edge 12a of the strip hole 12 is designed to restrict inward biasing.

That is, although the arm rod 16 with a ring is biased toward the inside of the door 2 by the elasticity of the spring 17, it is restricted by the upper edge 12a, which functions as a stopper, and has a habit of coming into close contact with the door 2 when the door is opened. is given.

On the other hand, a plate-shaped operating rod 18 is fixedly connected to the base 16 a of the arm rod 16 with a ring, and this operating rod 18
The free end of the door 2 comes into contact with the contact surface of the lower side plate 1a of the main body 1 and enters the notch 12 when the door 2 is opened.

Therefore, when a passenger gets into a car and opens the door 2, the arm rod 16 with the ring is in close contact with the inner side of the door 2 due to the elasticity of the spring 17, as shown in FIG. The second seat belt 11 is held up and the lower part of the second seat belt 11 is lifted up, and the first seat belt 5 is pulled out from the retractor 4. When the passenger gets on and off, a sufficient space is secured for the passenger to get on and off, making it easy and smooth for the occupant to get on and off. You will be able to do it.

Next, when the door 2 is closed, the free end 18a of the operating rod 18 comes into contact with the contact surface of the lower side plate 1a of the vehicle body 1, and the operating rod 18 is connected to the ring-equipped arm on the rotating shaft 15. Rod 1
6 and rotates against the elasticity of the coil spring 17.

Then, this arm rod 16 with a ring is attached to the second seat belt 11.
At the same time, the occupant seated on the seat 3 falls down, that is, on the inside of the vehicle body 1, and on the other hand, by the operation of the retractor 4, the first
The seat belt 5 is unwound, and the second seat belt 11 can be attached to a predetermined position of the occupant, that is, around the waist.

Although the second seat belt 11 in the above-mentioned embodiment has been described as being drawn through the hole 6a of the through ring 6, there is a risk that the through ring 6 may be misaligned due to its own weight each time. Therefore, it is desirable to provide a clip (grip member) 19 having a striped hole 19a by passing it through the second seat belt 11 in the vicinity of the through ring 6, as shown in FIGS. 2 and 4. .

The clip 19 shown in FIGS. 5A and 5B is another embodiment of the above-described clip 19, in which a pair of parallel holes 19a are bored in the upper surface of the flat clip 19.
The second seat belt 11 is drawn through this hole 19a, thereby preventing the second seat belt 11 from being misaligned.

Furthermore, the clip 19 shown in FIGS. 5C and 5D is a modification of the clip 19 shown in FIGS. 5A and 5B, and
In this case, the rib 19b that the second seat belt 11 comes into contact with has a circular cross section, and is substantially the same as the above-mentioned specific example.

Moreover, the clip 19 shown in FIGS. 5E and F is
This is a modification of the clip 19 shown in Figures C and D, in which the rib 19b that the second seat belt 11 abuts has a rectangular cross section.

FIG. 6 shows another embodiment of the present invention, in which a lug 16C is provided at the base 16a of the arm rod 16 with a ring,
An actuating rod 18 is pivotally attached to this lug 16C with a pin 28, and a guide pin 25 is fitted into a hole 18b formed in the actuating rod 18, so that when the door is closed, By pushing the operating rod 18 against the elasticity of the spring 17, the ring-equipped arm rod 16 is moved to the rotation shaft 15.
This is a modification of the first embodiment.

As mentioned above, the present invention uses an actuating device that utilizes the force of opening and closing the door to actuate the seatbelt to restrain or release the occupant, so the structure is extremely simple and compact, and assembly and adjustment are easy, making it possible to mass-produce. It is possible to save labor and provide the product at a low cost, and since the arm bar rotates in the vertical direction, the arm bar does not hit an obstacle in front of the seat when the door is opened.
