The intermediate portion 12a of the seat belt (webbing) 12 is provided between them (FIG. 4).
) Is provided with a seatbelt insertion gap 11 having a width W enough to allow insertion.

The intermediate portion 12a of the seat belt 12, one end of which is fixed to the vehicle body and the other end of which is connected to a winding device (not shown), is inserted into the seat belt mounting portion 10 through the seat belt insertion gap 11. By being inserted and arranged, the intermediate portion 12a of the seat belt 12 is slidably guided (see FIG. 2).

Further, the seat belt guide 5 of the present embodiment is integrally formed with a downwardly extending piece portion 13 extending downward at a distal end portion of the lower surface thereof. Specifically, as clearly shown in FIG. 3, the lower surface 8a of the belt guide portion 8 which constitutes the lower portion of the seat belt guide 5 and is disposed substantially horizontally, is provided at the tip of the protruding side. A hanging piece 13 which is substantially perpendicular to the guide 8 downward is bent and formed. The hanging piece 13, the lower surface 8 a of the belt guide 8 of the seat belt guide 5, the side 4 a of the headrest 4, and the shoulder 3 a of the seat back 3 form an auxiliary seat belt mounting space 14. Is formed.

On the other hand, as shown in FIG. 4, a strut tower (not shown) for mounting a strut body of the suspension assembly is provided at a rear portion of the headrest 4, and this strut tower has an external appearance. It is obscured by the tower trim 16 for improvement. In the recess 16a of the tower trim 16, a shoulder anchor sash guide 19 composed of a flat shoulder anchor portion 17 and a ring portion 18 connected to the shoulder anchor portion 17 is rotatably mounted along a horizontal plane. ing.

Although not shown, a latch is attached to an intermediate portion of the seatbelt 12, and the seatbelt 12 is attached to a buckle attached to the vehicle body so that the seatbelt 12 is seated. It is designed to be mounted on the occupant's body while crossing the cushion 2 and the seat back 3 (see FIG. 4).

According to the seat belt guide device having such a structure, the guide position of the seat belt 12 can be appropriately selected for both the occupant having the standard sitting height and the occupant having a low sitting height such as a child. Thereby, a good seat belt wearing state can be achieved. That is, when an occupant having a standard sitting height (standard occupant) sits on the vehicle seat 1, the intermediate portion 12a of the seat belt 12 is inserted through the seat belt mounting portion 10 provided on the seat belt guide 5 itself. While wearing the seat belt 12
As shown in FIG. 4, an occupant with a low sitting height (occupant such as a child) A
When the user sits on the vehicle seat 1, the seat belt 12 is fastened by inserting the intermediate portion 12 a of the seat belt 12 into an auxiliary seat belt fastening space 14 provided below the seat belt guide 5. What should I do? This prevents the seat belt 12 from rubbing against the occupant's neck or the like when the seat back 3 is tilted backward.

More specifically, in the case of a standard-sized occupant, even if the intermediate portion 12a of the seat belt 12 is guided by the seat belt attaching portion 10 and the guide position is relatively high, the occupant may not move. Is high, the middle portion 12a of the seat belt 12 is properly attached to the occupant's shoulder, and the seat belt 12 rubs against the occupant's neck even when the seat back 3 is tilted backward. There is no such thing. In the case of a small occupant such as a child, the intermediate portion 12a of the seatbelt 12 is guided by the auxiliary seatbelt mounting space portion 14 disposed immediately below the seatbelt mounting portion 10, Under a normal sitting posture, the seat belt is detached from the occupant's neck and is attached to a position closer to the shoulder, and the intermediate portion 12a of the seat belt 12 is detached from the occupant's neck when the seat back 3 is tilted backward. Position, and the seat belt 12
Rubbing on the neck can be avoided. Accordingly, it is possible to selectively use the occupants of all types according to their types.

Further, since the auxiliary seatbelt mounting space 14 has no space other than the space 15 for seatbelt insertion, the seatbelt 12 is largely shifted left and right when the seatbelt is mounted and falls out of the space 14. There is no danger that the seat belt 12 will be guided.

Further, since the seat belt guide 5 used in this embodiment has a very simple structure in which the hanging piece 13 is provided in the conventional structure, there is an advantage that the manufacturing cost is low.

As described above, one embodiment of the present invention has been described.
The present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention. For example, the shape of the hanging piece 13 of the seat belt guide 5 can be changed to any shape as long as it can prevent the seat belt 12 from dropping from the seat belt mounting space 14 to the side.

[0024]

As described above, according to the present invention, a downwardly extending hanging portion is provided at the tip of the lower surface of a seat belt guide attached to a side portion of a headrest, and a shoulder portion of a seat back and a hanging portion of a seat belt guide are provided. A gap for seatbelt insertion is formed between the seatbelt and the lower part, and the hanging piece, the lower surface of the seatbelt guide, the side of the headrest, and the shoulder of the seatback form an auxiliary seatbelt mounting space. Therefore, when an occupant with a standard sitting height is seated in the vehicle seat, the seat belt is inserted into the seat belt mounting portion provided on the seat belt guide itself, and the seat belt is worn, so that the child can wear the seat belt. When an occupant with a low sitting height sits on the vehicle seat, the seat belt is inserted into the auxiliary seat belt mounting space and the seat belt is mounted. If so done, in any case it is possible to obtain a good seat belt fit. In particular,
In the latter case, when the seat back is tilted backward while the seat belt is being worn, the intermediate portion of the seat belt is regulated to a lower position than in the former case,
It is possible to avoid such a problem that the middle portion of the seat belt is rubbed on the neck of a small occupant or the like.

Therefore, according to the seatbelt guide device according to the present invention, since the seatbelt guide is provided with the hanging pieces, the seatbelt guide can correspond to the standard body type and the smaller body type, respectively. The seat belt guide and the seat belt can be used for the occupant.

Further, since the auxiliary seat belt mounting space has no space other than the space for inserting the seat belt, there is no possibility that the seat belt is largely shifted left and right or slips off when the seat belt is mounted.

In addition, the seat belt guide device according to the present invention can provide the above-mentioned practical functions and effects, but requires only a simple structure in which the seat belt guide is provided with the hanging piece. There is an advantage that the structure is simple and inexpensive.
