Description

[Detailed Description of the Invention] This invention relates to a wrap inner anchor device in which a wrap inner belt of a seat belt device is moved back and forth in response to the adjustment of the seat back and forth position.

Conventionally, when the anchor part of the wrap inner belt was fixed to the floor side of the vehicle body, each time the seat was adjusted in the longitudinal direction using the seat track,
The length of the belt was adjusted to satisfy the feeling of wearing the belt on the passenger.

In this way, it has been desired to further improve performance in the future since it is necessary to manually adjust the belt length each time the seat is adjusted fore and aft.

The purpose of this invention is to move the wrap inner belt back and forth in response to the adjustment of the front and back position of the seat, and to reduce the load applied to the wrap inner belt when a load exceeding a predetermined value is applied to the wrap inner belt. By equipping the seat with a wrap inner attachment means that is anchored to the floor side of the vehicle body, it is possible to eliminate the need for manual adjustment of the belt length when adjusting the seat back and forth, thereby further improving the above-mentioned conventional performance.

In order to achieve such a purpose, the structure of the wrap inner anchor device of this invention is such that a slot 3 is provided in a seat bracket 1 fixed to an upper rail T1 of a seat track T whose position is adjusted in the longitudinal direction with respect to the vehicle floor F. A vertical wall 2 is formed, and a wrap inner anchor bracket 5 is attached to a slot 3 of the vertical wall 2 with a fixing member 4 such as a bolt.

Further, a wrap inner belt 6 is attached to one end 50 of the wrap inner anchor bracket 5, and a slider 7 is attached to the other end 51, and the slider 7 is fixed to the vehicle body floor F. It is slidably inserted into the slide rail 8. When a load of more than a predetermined value is applied to the wrap inner belt 6, the above-mentioned fixture 4 to which the wrap inner anchor bracket 5 is attached pushes open the slot 3 of the vertical wall 2, and the wrap inner anchor bracket 5 and the vertical wall are separated. 2, and the load applied to the wrap inner anchor bracket 5 is transferred to the vehicle body floor F via the slide rail 8.

According to the wrap inner anchor device according to this invention, the seat bracket 1 fixed to the upper rail T1 of the seat track T is provided with a standing wall 2 in which a slot 3 is formed, and a fixing device 4 such as a bolt is inserted into the slot 3 of this standing wall 2. When the wrap inner anchor bracket 5 is attached and a load of more than a predetermined value is applied to the wrap inner belt 6, the fixing tool 4 to which the wrap inner anchor bracket 5 is attached will
Since the slot 3 of the standing wall 2 is pushed open to release the fixation between the wrap inner anchor bracket 5 and the standing wall 2, the following effects (a) and (b) are achieved.

(b) Since the wrap inner belt moves back and forth in response to the longitudinal adjustment of the seat, there is no need to manually adjust the belt length when adjusting the seat longitudinally.

(b) When a load of a predetermined value or more is applied to the wrap inner belt, the load applied to the wrap inner anchor bracket can be borne by the vehicle body floor via the slide rail.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Figures 1 to 5b show an embodiment of this invention, and the seat S in Figure 1 can be adjusted in position in the longitudinal direction with respect to the vehicle floor F by operating an adjustment lever L. As can be seen from Fig. 4, this seat track T is, in detail, composed of an upper rail T1 and a lower rail T2, and the lower rail T2 is fixed to the floor F of the vehicle body. A seat bracket 1 is fixed to the upper rail T1, and a seat cushion SC is attached to the seat bracket 1 by bolts B. Further, a seat back SB is attached via a hinge pin P.

On the other hand, this seat bracket 1 is formed with a standing wall 2, and as seen from FIGS. 2 and 3, a slot 3 is provided in this standing wall 2. Attach the wrap inner anchor bracket 5 using a fixing device 4 such as a bolt.
is installed.

Further, the wrap inner belt 6 is attached to one end 50 of the wrap inner anchor bracket 5 with a bolt B.
A slider 7 is attached to the other end 51 of the wrap inner anchor bracket 5 via a lock pin LP, and this slider 7 is attached to the tunnel side F1 of the vehicle floor F.
It is slidably and loosely inserted into a slide rail 8 which is fixed by a fixture (not shown).

The slide rail 8 is provided with a plurality of grooves 9 in its flange 80, as can be seen from FIGS. 5a and 5b.

When a load of more than a predetermined value is applied to the wrap inner belt 6, the fixing tool 4, which has the wrap inner anchor bracket 5 attached to the slot 3 of the vertical wall 2, opens the slot 3 of the vertical wall 2 as shown in FIG. Push it open in the direction of arrow A to release the fixation between the wrap inner anchor bracket 5 and the standing wall 2, so that the load applied to the wrap inner anchor bracket 5 is transferred to the vehicle body floor F via the slide rail 8. There is.

Next, the operation of the wrap inner anchor device of this invention will be explained.

As shown in Figure 1, the center pillar of the car body
Seat belt tongue plate fixed to CP
The TP is fitted and attached to the buckle BL provided at the free end of the wrap inner belt 6. On the other hand, when the adjustment lever L shown in FIG. The installed wrap inner anchor bracket 5 is attached to the seat S.
At the same time, it is moved back and forth.

At this time, the slider 7 attached to the other end 51 of the wrap inner anchor bracket 5 slides within the slide rail 8 in accordance with the slide of the upper rail T1.

Next, when a load from the occupant is applied to the wrap inner belt 6, that load is transmitted to the wrap inner anchor bracket 5. However, when a load of more than a predetermined value is applied to the wrap inner belt 6, the vertical wall 2
Fixture 4, which attaches the wrap inner anchor bracket to
Therefore, the load applied to the wrap inner anchor bracket 5 is not borne by the seat bracket 1 side, but is borne by the vehicle body floor F side via the slide rail 8. Become.

At this time, the lock pin LP at the other end 51 of the wrap inner anchor bracket 5 changes from the unlocked state shown in FIG. The inner anchor bracket 5 is locked on the vehicle floor F side.
