Abstract

PURPOSE:To enable the position of a reacher in a state of desirable operation suited to the physique of a passenger to be selected by only simple operation by using a knob to connect and disconnect the engagement made in a plurality of positions between a pole on a guide plate and a ratchet, having a plurality of teeth, provided on the reacher. CONSTITUTION:On a guide plate 15 guided by means of a base plate 7 are provided a pole 20 and a knob 19, and then, on a seat belt reacher 21 axially supported by the base plate 7 is provided a ratchet 25 having a plurality of teeth. In addition, the guide plate 15 is energized in one direction by means of a return spring 18, and at the same time, the reacher 21 is energized in the vertical direction. And further, the engagement and disengagement between the pole 20 and the ratchet 25 is enabled to perform by a simple operation of the knob 19. And moreover, the position of engagement between the pole 20 and the ratchet 25 is increased to the number of a plurality so that the position of the reacher 21 in a state of operation is increased to the number of a plurality. Thereby, the reacher 21 is enabled to become a desirable operating state suited to the physique of a passenger.

Description

DETAILED DESCRIPTION OF THE INVENTION Object The present invention relates to a seat belt reacher device for a motor vehicle.

As shown in FIG. 1, the belt 1 from the belt retractor is positioned behind the seat 2 as shown by the imaginary line. Therefore, when the occupant tries to put on the belt 1, it is necessary to grasp the belt tongue 3 located far back and pull the belt 1 forward. In particular, in a two-door car, the belt 1 is positioned far behind the seat 2, making it troublesome to hang the belt. For this reason, by disposing the arm-shaped seat belt reacher 4 at the anchor through 5 part and holding the seat belt reacher 4 approximately horizontally, the reach key operation state yF
! 4' (shown as a solid line in Figure 1), and belt tongue 3
is moved in advance near the seat 2 to facilitate belt hanging.

When the passenger in the rear seat gets on or off, the seat belt reacher 4 is grasped by hand and rotated around the anchor through 5 to create a reacher stowed state in which it is lowered along an imaginary line. Relatively large#
Rotating the long seatbelt reacher 4 while holding it in the hand still poses a problem in terms of operability. In addition, since the seat belt reacher 4 has only two states, operating and retracting, when it is in the operating state, the belt 1
The crew member Sechika <K<ru. Sometimes, the belt 1 even comes into contact with the occupant's face.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve the operation of the seat belt and to provide a plurality of operating positions of the seat belt reacher, thereby solving the above-mentioned problems of the prior art.

Configuration In order to achieve the above-mentioned object, the present invention attaches an I-rule and a knob to a guide plate guided by a pace plate, and a ratchet having a plurality of teeth to a seat belt reacher that is pivotally supported on a base plate. A technical means is used in which the pawl and the ratchet are engaged and disengaged using a knob, and the pawl and the ratchet engage with each other at a plurality of positions, thereby making it possible to select the operating state position of the seat pel IJ-char.

Embodiments of the present invention will be described with reference to FIGS. 2-4.

The seat pelt reacher device 6 has an anchor bolt 8 supported by a base grate 7.

A collar 10 is disposed between the pace grate 7 and the center pillar panel 9, and a collar 11 is also disposed on the inside of the pace grate T. -4-012 water nuts.

The base plate 7 has first and twentieth elongated holes 13.14.
The leg piece 1 of the guide plate 15 is inserted into the tenth elongated hole 13.
6, and the stud of the rivet 17 fixed to the guide plate 15 is passed through the 20th elongated hole 14, so that the guide plate 15 is guided by the elongated hole 13.14 of the base plate T, and is slidable relative to the base plate γ. .

A return spring 18 is stretched between the leg piece 16 and the flange portion of the base grate T to bias the guide plate 15 in one direction. Knob 19 and I on guide plate 15
- Fix the lever 20.

One char 21 around the collar 11 on the anchor bolt 8
The reacher 21 is urged in the vertical direction as seen in FIG. 1 by the second return spring 22. The reacher 21 has a toothed portion 23 and a toothed portion 23 at the end thereof.
A ratchet 25 having an arcuate surface 24 that follows is fixed.

The tooth portion 23 has a plurality of teeth. The tooth portion 23 can freely mesh with the pawl 20, and the arcuate surface 24 can come into contact with the pawl 2G.

The anchor gel 8 supports the anchor through 5, and
The belt guy 26 is held at the tail of the reacher 21. Belt 1 to belt guide 26 and anchor through 5
Wotsu f.

The second return spring 22 moves the reacher 21 by m
1, apply force in the vertical direction so that the guide plate 150 and the pawl 20 come into contact with the circular arc surface 24 of the ratchet 25 and also against the stopper portion 27 of the ratchet 25. mosquito(
The reacher 21 is normally in the stored state shown by the imaginary line in FIG. The contact between the pole 2G and the arcuate surface 24 at this time applies tension to the first return spring 1.

When the reacher 21 is moved horizontally around the anchor gel 8 against the urging force of the second return spring 22, the pawl 20 comes into contact with the arcuate surface 24 and the toothed portion 2
Change its position to 3. Paul 20 has teeth
23, the pawl 20 moves to the right in FIG. 3 together with the guide plate 15 due to the first return spring 18, and the pawl 20 and the teeth 23 are kept in mesh with each other, and the reacher 21 will be fixed to the base plate T. The operating state shown in solid lines in FIG. 1 is thus obtained.

In the illustrated example, as shown in FIG. 4, the tooth portion 23 is (A),
(b), (Made with three teeth of / number, pole 20 is (a)
When the reacher 21 engages with the teeth of the 90 degrees.

It is made to tilt with respect to the vertical direction by 75 degrees at (e+) and 60 degrees at V→.

To move from the activated state to the stowed state, the knob 19 is simply pushed in against the first return spring 18. This pushing causes the ball 20 to separate from the teeth 23, so that the reacher 21 is automatically moved to the stored state by the second return ring 22. That is, the state shown in FIG. 2 is reached in which the ball 20 abuts against the arcuate surface 24 of the ratchet 25 and the stopper portion 2T.

The effect activation state can be released by simply pushing the knob, so the operation is extremely simple. Furthermore, since the reacher can be put into a plurality of operating states, it is possible to obtain a desirable operating state of the reacher that matches the physique of the occupant.
