DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for accommodating a seat belt buckle in a vehicle seat, and is particularly suitable for a rear seat.

[0002]

2. Description of the Related Art Seat belts are provided not only for front seats but also for rear seats, so that all occupants can be safely restrained by the seat belts. In general, a separate type seat is adopted as a front seat, and a seat belt buckle to which a tongue of a seat belt is disengaged is fixed to a vehicle body side beside the front seat. The rear seat is a bench type seat, and the seat belt buckle is stored in a storage hole formed in the rear seat. The seat belt is taken out of the storage hole when the seat belt is worn.

A conventional structure for storing a seat belt buckle in a rear seat will be described with reference to FIG. FIG.
1 shows a perspective view of a rear seat provided with a conventional seat belt buckle storage structure.

As shown in the figure, an armrest 3 is accommodated in a central portion of a seat back 2 of a rear seat 1, and the armrest 3 is used as needed when an occupant does not sit in the center of the rear seat 1. I have. A slit 5 is formed in a rear portion of the seat cushion 4 of the rear seat 1, and a support member 7 to which a seat belt buckle 6 is attached is rotatably about an axis extending in the vehicle width direction on a vehicle body side corresponding to the slit 5. It is freely supported. The seat belt buckles 6 are provided for the left and right occupants, respectively, with the central portion of the seat cushion 4 interposed therebetween. A storage hole 8 is formed at the lower end of the seat back 2 beside the armrest 3, and the seat belt buckle 6 is stored in the storage hole 8 when the seat belt of the rear seat 1 is not used. The passenger is the rear seat 1
When the user wears the seat belt, the support member 7 is rotated to take out the seat belt buckle 6 from the storage hole 8, and the seat belt buckle 6 is placed on the seat cushion 4.
To protrude. When the seat belt is not used, the support member 7 is rotated to store the seat belt buckle 6 in the storage hole 8 so that the seat belt buckle 6 does not exist on the seat cushion 4. Therefore, when the occupant does not sit on the rear seat 1, the seat belt buckle 6 is stored in the storage hole 8, and the seat belt buckle 6 does not obstruct or deteriorate the appearance.

[0005]

According to the conventional seat belt buckle storage structure, the seat belt buckle 6 is stored in the storage hole 8 so that the seat belt buckle 6 can be stored.
To prevent exposure. However, since the storage hole 8 is formed beside the armrest 3 so as not to deteriorate the appearance of the seat back 2, the position of the storage hole 8 is determined to some extent by the width of the armrest 3. The width cannot be made large. Therefore, when three persons are seated on the rear seat 1, the seat belt buckle 6 is present at the seating position of the center occupant. In addition, since the seat belt buckle 6 is stored in the storage hole 8 formed in the seat back 2 by rotating the support member 7, the mechanism for attaching the support member 7 to the vehicle body becomes complicated and the seat is buckled. When the belt is worn, the seat belt buckle 6 protrudes greatly above the seat cushion 4. Therefore, in the conventional seat belt buckle storage structure, the support structure of the seat belt buckle 6 becomes complicated, and when three people are seated on the rear seat 1 and the seat belt is worn, the center occupant is in the seating position. The seat belt buckle 6 would protrude greatly, giving the occupant in the center an uncomfortable feeling.

On the other hand, a seat belt buckle is stored in a pocket constituted by a storage portion and a cover portion constantly urged to a closed side, and when the seat belt buckle is stored, the seat belt buckle is covered by the cover portion. A storage structure (Japanese Utility Model Laid-Open No. 4-112153) that prevents the appearance of the seat back from lowering has also been proposed. According to this structure, the seat belt buckle can be supported with a relatively high degree of freedom, and the seat belt buckle can be provided so as to avoid the seating position of the center occupant to some extent. However, when the seat belt is worn, it is necessary to perform the opening / closing operation of the lid and the rotation operation of the seat belt buckle, so that the operation becomes very complicated. Further, the structure becomes complicated, the cost increases, and the feasibility is extremely low.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a very simple structure to prevent the appearance of a seat from being deteriorated and to provide a seat belt buckle in which a seat belt buckle can be provided while avoiding a seating position of an occupant. The purpose is to provide a structure.
