However, in the buckle storage structure disclosed in Patent Document 1, the buckle is stored so as to face the vehicle width direction and to be retracted from the storage portion. Moreover, the seatback of the rear seat for three people is partially divided. The seat back is tilted so that when the seat back is tilted forward, the buckle exposed from the storage part protrudes from between the seat back and the seat cushion. As a result, the buckle that leaks out may interfere with a rigid seat structure such as a seat frame, and the buckle may be damaged.

An object of the present invention is to prevent the buckle exposed from the seat cushion from being interfered with and damaged by the rigid seat structure even when the seat is tilted.

In order to achieve the above-mentioned object, the buckle storage structure of the seat belt of the present invention is a buckle storage structure of a seat belt for storing a buckle of a seat belt so that the buckle of the seat belt can be retracted, inside a seat cushion that constitutes a vehicle seat. A storage recess formed in the seat cushion and having a shape longer in the vehicle width direction than the vehicle front-rear direction, and an end portion fixed to a fixing portion of the seat and led out of the seat cushion through the storage recess. A buckle and a regulation unit that is provided in the storage recess and that regulates the leading direction of the buckle so that the buckle faces the vehicle front-rear direction, and the regulation unit is disposed in the storage recess and has one end is fixed to the connecting portion between the buckle webbing, the other end is characterized by elastic members der Rukoto fixed to the seat cushion side.

According to the present invention, the elastic member is disposed in the storage recess having a shape that is longer in the vehicle width direction than in the vehicle front-rear direction, and has one end fixed to the connection portion with the webbing of the buckle and the other end fixed to the seat cushion side. The restricting means restricts the buckle leading direction so that the buckle led out from the storage recess of the seat cushion faces the vehicle front-rear direction. It is possible to prevent it from protruding between the tilted seat back and the seat cushion, and even if the seat is tilted, the buckle exposed from the seat cushion interferes with the rigid seat structure and is damaged. Can be prevented in advance.

It is a perspective view of the storage recessed part in FIG. It is sectional drawing in the XX line of FIG. It is a schematic diagram showing a fixed state of the buckle of FIG. It is a perspective view of the buckle peripheral part of FIG. It is a perspective view in the state with a buckle of FIG.

An embodiment in which a buckle storage structure for a seat belt according to the present invention is applied to a rear seat will be described in detail with reference to FIGS. 1 to 6. In addition, the front-rear and left-right in the present embodiment mean the front-rear and left-right as viewed in a state of sitting on the seat.

As shown in FIG. 1, a three-seat rear seat 1 includes a seat back 1a and a seat cushion 1b, and the seat backs 1a1 and 1a2 and the seat cushions 1b1 and 1b2 are divided at a ratio of 6 to 4, for example. The backs 1a1 and 1a2 are configured to be able to tilt forward. The rear seat 1 is provided with a three-point rear seat belt for restraining three occupants, and a winding device (retractor) for winding the webbing, which is each belt portion, is a predetermined device such as a ceiling or a seat back. Buckles that engage with the tongues provided on each webbing in a detachable manner.

As shown in FIG. 1, a storage recess 2 is provided in the seat cushion 1b2, and one buckle 3 is retractably stored in the storage recess 2. At this time, as shown in FIG. 2, the storage recess 2 has an opening formed in the seat pad of the seat cushion 1b2 in the vehicle width direction longer than the front-rear direction of the vehicle, and a cloth for closing a part of this opening. And a cover 2a.

Specifically, as shown in FIG. 3, an opening 1d having a shape that is longer in the vehicle width direction than in the vehicle front-rear direction is formed in the seat pad 1c, and a cloth cover 2a is provided in a portion other than the front side of the opening 1d. The outer skin 1e of the seat cushion 1b2 and the left and right sides and the rear side of the cloth cover 2a are sewn together to form a lead-out opening 2b having a width equal to or slightly smaller than the thickness of the buckle 3 in the vehicle width direction. The buckle 3 can be retracted from the outlet 2b without the cloth cover 2b. Since the cloth cover 2a has elasticity, when the buckle 3 is pulled out from the outlet 2b, the cloth cover 2a extends and the buckle 3 can be easily pulled out from the outlet 2b. Further, since the outlet port 2b is formed by the cloth cover 2a to have a width equal to or slightly smaller than the thickness of the buckle 3 and long in the vehicle width direction, the outlet direction of the buckle 3 from the outlet port 2b is restricted in the vehicle front-rear direction. Contribute to that.

As shown in FIG. 4, the buckle 3 has one end of a short webbing 3b connected to the buckle body 3a, and the other end of the webbing 3b fixed to a fixed object such as a seat structure or a vehicle structure. The buckle body 3a is connected to the V-shaped bracket 5 so that the buckle body 3a can be retracted from the outlet 2b of the storage recess 2 to be retracted.

Further, as shown in FIG. 5, one end of a rubber band 6 disposed inside the storage recess 2 is fixed to a connecting portion between the buckle body 3a and the webbing 3b, and the other end of the rubber band 6 is As shown in, the S-shaped spring 8 arranged on the lower surface side of the seat cushion 1b2 is fixed, and the buckle body 3a of the buckle 3 led out from the lead-out port 2b of the storage recess 2 faces the vehicle front-rear direction. Biased in the direction.

In this way, due to the action of the outlet 2b and the rubber band 6, as shown in FIG. 6, the lead-out direction of the buckle 3 led out from the outlet 2b of the storage recess 2 is restricted so as to face the vehicle front-rear direction. The outlet 2b and the rubber band 6 correspond to the restricting means in the present invention.

Then, in the configuration in which the seat back 1a2 is tilted by restricting the lead-out direction of the buckle 3 led out from the lead-out port 2b of the storage recess 2 to the vehicle front-rear direction, for example, with the seat back 1a2 with the buckle 3 tilted. It can be prevented from protruding from between the seat cushion 1b2 and the buckle 3 exposed from the seat cushion 1b2 does not interfere with the rigid seat structure even when the seatback 1a2 is tilted.

Therefore, according to the above-described embodiment, the buckle 3 led out from the storage recess 2 of the seat cushion 1b2 is oriented in the vehicle front-rear direction by the narrow outlet 2b and the rubber band 6 provided in the storage recess 2. Since the pull-out direction of the buckle 3 is restricted, even if the seat back 1a2 is tilted, it is possible to reliably prevent the buckle 3 from protruding from between the tilted seat back 1a2 and seat cushion 1b2. It is possible to prevent the buckle 3 exposed from the seat cushion 1b2 from interfering with and breaking the rigid seat structure when the 1a2 is tilted.

The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

For example, in the above-described embodiment, an example in which the restricting means in the present invention is configured by the outlet 2b having a width narrower than the thickness of the buckle body 3a and long in the vehicle width direction and the rubber band 6 having an urging force is shown. The rubber band 6 may not be provided, and only the outlet 2b of the storage recess 2 may be used to restrict the lead-out direction of the buckle 3 led out from the outlet 2b to face the vehicle front-rear direction. Further, instead of the rubber band 6 as the restricting means, a spring material or other elastic member may be used.

Further, in the above-described embodiment, the case where the buckle storage structure of the seat belt according to the present invention is applied to the rear seat has been described. However, a seat other than the rear seat, the buckle stored inside the seat cushion is derived and used. Any sheet having the above structure can be applied in the same manner as the present invention.
