Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear seat of an automobile, which has a retractable rear seat with a retractable seat back, and a three-point seat belt for the rear seat. Further, the present invention relates to a belt holding device for a seat belt in an automobile, which prevents the belt of the seat belt from being sandwiched between the vehicle interior trim and the vehicle interior trim.

[0002]

2. Description of the Related Art Some vehicle rear seats have a retractable seat back for enlarging the luggage carrier. On the other hand, in recent years, an increasing number of vehicles have adopted a three-point type seat belt for the rear seats.

In such an automobile, when the seatback of the rear seat is raised, if the seatback is raised without holding the belt of the seatbelt, the belt of the seatbelt is sandwiched between the seatback and the trim in the vehicle compartment. Sometimes.

FIG. 9 and FIG. 10 show a belt holding device for a seat belt in an automobile which has been generally used in the past. FIG. 9 shows a belt holding device for a seat belt of a three-door vehicle including a retractable rear seat 100 and a three-point seat belt 101. The retractable rear seat 100 is a seat cushion 10
2 and the seat back 103, and is provided with a lock portion (not shown) that engages with the rear seat striker mounted on the body side.

A seat belt hook 107 for preventing the belt 106 of the seat belt 101 from being caught is provided on the surface of the quarter trim 105 below the rear window 104 in the vehicle compartment.

The belt 10 of the seat belt 101
6 is engaged with the seat belt hook 107 to prevent the belt 106 from being caught when the seat is locked.

On the other hand, FIG. 10 shows a case of a four-door vehicle, in which the seat belt hook 110 is attached to the quarter trim 109 behind the rear door 108 with the screw 111.

However, the one shown in FIG. 9 cannot be applied to a four-door vehicle, and the one shown in FIG. 10 is difficult to mount with screws or the like. Further, in this case, since the seat belt hook 110 conforms to the shape of the quarter trim 109, the shape changes between the left and right, so that the left and right parts cannot be shared.

Therefore, one type of vehicle body specification can be used regardless of the presence or absence of the three-point seat belt, and the number of assembling steps and cost can be reduced because the screw or the clip is not used for attaching the seat belt hook. I filed an application for a seatbelt entanglement prevention device that can be used (Japanese Patent Application No. 3-65615). In this prior art, as shown in FIGS. 11 to 13, a rear seat striker 112 is mounted on a quarter panel (not shown) arranged on the lower surface of a quarter trim via a base, and a striker body 113 of the rear seat striker 112 is mounted. The seat belt hook 115 is assembled by fitting the annular portion 114 to the.
This seat belt hook 115 is provided with a hook portion 117 extending along the curved surface of the quarter trim 116 on one side of the annular portion 114, and on both sides and the rear side of the back surface of the annular portion 114, facing outward. The claw 118 is provided at three places.

The seat belt hook 115 has an annular portion 11.
The seat belt hook 115 is provided with a cutting part in the middle of 4.
One side 115a is expanded outward, and this one side 115a
Is reduced in the radial direction, the quarter trim 11
6 is inserted into the through hole 119, and the one side 115a is expanded after the insertion, and the through hole 119 of the quarter trim 116 is inserted.
The seat belt hook 115 by engaging the claw portion 118 with
Is fixed.

According to this prior art, when a three-point type seat belt is used in an automobile having a retractable rear seat, the seat belt hook 115 is attached to the rear seat striker 112.

The seat belt hook 115 includes an annular portion 11.
4 is fitted into the striker main body 112a and the one side 114a of the annular portion 114 is pressed, and the claw portion 118 is inserted into the insertion hole 121 of the quarter trim 116. Then, when the one side 114a of the annular portion 114 is released, the claw portion 118 expands and engages with the edge portion of the insertion hole 119. Thus, the seat belt hook 115 is assembled to the rear seat striker 112, and the belt 106 of the seat belt 101 is held by the hook portion 117 of the seat belt hook 115. If the claws 118 alone are not sufficient, the clip 120 is press-fitted between the claws 118 and the claws 118 are widened to prevent the claws 118 from coming off, and the seat belt hook 11
Fix 5

[0013]

According to the above prior art, since the structure of the seat belt hook 115 is complicated, dimensional accuracy is required in the molding process, resulting in high cost. Since the seat belt hook 115 is attached using the rear seat striker 112, the quarter trim 11
Depending on the shape of 6, it is necessary to mold parts for each vehicle type. In addition, setting the attachment position when attaching the seat belt hook 115 to the vehicle body side is troublesome.

The present invention solves the above-mentioned problems and can cope with one type of vehicle body specification regardless of the presence or absence of a three-point type seat belt, and at the same time, can improve the assembling property and the holding force of the seat belt hook. An object of the present invention is to provide a belt holding device for a seat belt capable of

[0015]

In order to solve the above-mentioned problems, the present invention comprises a retractable rear seat provided in a rear seat of an automobile and a three-point seat belt equipped for the rear seat. In the belt holding device of the seat belt,
A belt hook is attached to the side surface of the seat back of the rear seat, and the belt holding portion of the belt hook is arranged on the front side of the seat back.

[0016]

The belt hook is mounted on the side surface of the seat back of the rear seat, and the belt holding portion of the belt hook is arranged on the front side of the seat back. When the tilted rear seat is raised, the belt of the seat belt is hooked on the belt holding portion of the belt hook so that the belt is not pinched beside the rear seat.
