Description

[Detailed Description of the Invention] This invention relates to a seated person holding position adjustment device for an automobile seat belt device that is capable of holding a small-sized seated person.

Conventionally, some seated person holding and position adjusting devices are provided with a belt shoulder portion that holds the seated person in the seat, and the upper part of this shoulder portion is connected to a holder whose vertical position is freely adjustable. (Publication number 57-27644).

However, in this configuration, since the holder is attached to the intermediate portion of the center pillar, the structure is complicated, such as the need to reinforce the center pillar in response to the load on the holder.

In addition, as shown in Japanese Utility Model Publication No. 55-37141, there is another configuration in which the adjustment device is attached to the belt, but with this configuration, it is difficult to remove the adjustment device from the belt. When the belt is stored in the take-up device, there is a risk that the adjustment device will hit the belt outlet, which is unfavorable in terms of handling.

Moreover, in both of the above configurations, although adjustment can be made in multiple stages, the adjustment device itself must be moved each time, making the operation complicated. Furthermore, as shown in Japanese Utility Model Application Publication No. 57-120045, there is another configuration in which a shoulder anchor is mounted on the upper part of the center pillar and a holder for the adjustment device is pivotally supported in the middle part of the center pillar. Then, when the seat is slid forward, the belt will put pressure on the seated person.

This invention was made with attention to the above-mentioned circumstances, and when a seated person with a small physique is held by a belt, this holding is performed with a simple structure and firmly. To provide a seated person holding position adjusting device for a seat belt device for an automobile, which prevents the seated person from being unnecessarily compressed by the belt when the seated person is held by the belt.

The feature of this invention to achieve the above object is that a shoulder anchor and a latch are attached to the upper part of the center pillar by tightening together, and this latch is used to attach the front of the seat occupant to the shoulder. The upper part of the belt that is held diagonally downward from the seat is removably hooked, thereby adjusting the holding position of the belt relative to the seated person downward.

Examples of this invention will be described below with reference to the drawings.

It is inserted so that it can move freely. The belt 9 from the shoulder anchor 14 to the connector 11 is
A holding portion 9a holds the front surface of the adult seat occupant 16 diagonally downward from the shoulder portion (indicated by a solid line in the figure).

A hook 17 is sandwiched between the shoulder anchor 14 and the center pillar 6, and are fastened together with the bolt 13. This latching tool 17 has a metal plate shape, the upper part of which is covered with a resin cover 18, and a mounting hole 19 for the bolt 13 is bored in the upper end. Further, an insertion hole 21 is formed in the lower part of the hook 17 and serves as a hook through which the belt 9 is movably inserted. A notch 22 is formed to allow the hook to be attached and detached. Further, the hook 17 is made longer than the shoulder anchor 14, and the insertion hole 21 is arranged below the sliding hole of the shoulder anchor 14. Then, the upper part of the holding part 9a is moved from the shoulder anchor 14 to the winding device 1.
When the belt 9 is inserted into the insertion hole 21 together with the belt 9 between the seats 2 and 2, and the belt 9 is hooked to the hook 17, the holding device for the seated person 16 is moved downward and the seated person 16 is small in size. (For example, a 6 year old child)
In this case, the seated person 16 is held in a proper state (as shown by the two-dot chain line in the figure).

The connector 11 has a fixed part 23 fixed to the floor 2 and a connecting part 24 detachably fixed to the fixed part 23, and one end of the belt 9 is movably inserted into the connecting part 24. At the same time, the extending portion 9b extending from this one end presses the knees of the seated person 16 and connects to another connector 2 provided on the other side of the seat 7.
6.

A garnish 27 is provided on the inner surface of the center pillar 6 to cover the belt 9 between the winding device 12 and the support 14.

The following figures show various embodiments of the hook 17, which will be described below.

4 and 5 show a second embodiment, in which the hook 17 has upper and lower plates 29 and 30 fixed with rivets 28, and the insertion hole 21 formed in the lower plate 30 is connected to the upper hole 2.

According to this invention, a hook longer than the shoulder anchor is attached to the center pillar together with the shoulder anchor, and the upper part of the belt holding part is removably hooked to the lower end of the hook. When the belt is hooked to the lower end portion of the hook, the position of the holding portion of the belt is lowered accordingly, making it possible to hold a seated person with a small physique. In the above configuration, the latching tool is attached to the center pillar by tightening the latching tool together with the shoulder anchor, so no separate mounting parts are required to attach the latching tool. Yes, this means that attachment of this latching device is achieved by a simple construction. Moreover, the above-mentioned hanging device is attached to the upper part of the center pillar together with the shoulder anchor, and since this upper part of the center pillar is normally connected to the side rail of the vehicle body, it is necessary to provide sufficient rigidity here. It is being Therefore, the above-mentioned hanging device is firmly supported on the vehicle body without requiring a separate reinforcing member, and in other words, it is possible to securely hold a seated person with a small physique. Furthermore, since the catch is longer than the shoulder anchor and they are pivoted at one point, when the seat is slid forward and the belt retainer is pulled forward, the catch will rotate forward. move. In other words, this latch follows the slide of the seat, thereby preventing unnecessary pressure from being applied to the seated person.
That is, in the past, the latch was approximately the same size as the shoulder anchor and was pivotally supported in the middle of the center pillar, so when the seat was slid forward and the belt holding part was pulled forward, this holding part was This results in the seated person being pinched and compressed by the seated person. However, with this invention, even if the seat slides forward as described above, unnecessary pressure is not applied to the seated person.
