Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a rear seat of an automobile, and more particularly to a structure for accommodating a seat belt buckle existing in the rear seat.

[0002] Conventionally, there is a rear seat equipped with a seat belt in order to ensure the safety of an occupant seated in the rear seat.

In such a rear seat, as shown in FIG. 5 or 6, from the corner 103 at the joint between the seat cushion 101 and the seat back 102, the seat belt buckle 104 is attached to the waving. (Bracelet) 105 is pulled out forward, and the seat belt buckle 104 is attached to the seat surface 101 of the seat cushion 101.
It is arranged at a.

When the seat having the above structure is folded, the button 1 provided on the seat back 102 in the structure shown in FIG.
The groove 107 formed on the back side of the seat belt buckle 104 is hooked on 06, and the seat back 102 is folded.
Further, in the structure shown in FIG. 6, the storage recess 108 is formed in the seat back 102, and the storage recess 1 is formed.
The seat belt buckle 104 is stored in 08, and the seat back 102 is folded.

[0005]

However, in the rear seat of the above-mentioned structure, the occupant's intention is to hook or store the seat belt buckle 104 in the seat back 102 when the seat is folded. There is a case where the seat back 102 is folded without performing the operation,
In such cases, scattered seat belt buckles 10
4 or the waving 105 with the seat belt buckle 104 attached to the front end of the seat back 102,
There is a concern that the skin of the seat cushion 101 may be damaged or the seat belt buckle 104 itself may be damaged.

There are also cases where the seat belt buckle 104 cannot be hooked or housed due to damage or deformation of the button 106 or the housing recess 108 formed on the seat back 102.

The present invention has been made in view of the problems of the above-mentioned prior art.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention attaches to a floor surface via a link mechanism so that the seat cushion moves forward and sinks downward when the seat back is tilted forward. In the back seat,
A self-supporting arm with a seat belt buckle attached to the tip is rotatably attached to the floor surface, and a recess for accommodating the seat belt buckle is formed between the seat back and the seat cushion, and the seat back is tilted forward. In this case, the seat belt buckle is pushed by the seat back to be housed in the recess, and when the seat back is raised, the seat cushion is pushed up by the seat cushion floating upward so that the seat belt buckle stands up in a use state. Configured to.

[0009]

With the structure of the rear seat according to the present invention, as the seat back is moved from the use position to the folding position, the seat belt buckle is automatically stored.
On the contrary, when the seat back is raised from the folded position to the use position, the seat belt buckle is automatically raised to the use state.

[0010]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a side view showing a structure of a rear seat according to the present invention, and FIG. 2 is a perspective view showing a use state of the rear seat according to the present invention. 3 is a perspective view showing a folded state of the rear seat according to the present invention, and FIG. 4 is a view of FIG.
It is an end view of the portion along the line A.

In the figure, reference numeral 1 denotes the entire rear seat, and the rear seat 1 is composed of a seat back 2 and a seat cushion 3. A lower end of the seat back 2 is rotatably arranged on an automobile floor 4 about a shaft 5, and an upper end of a bracket 6 arranged at a rear portion of the seat cushion 3 is provided at a lower part of the seat back 2 with a shaft 7. It is attached so as to be rotatable around. Further, the front portion of the seat cushion 3 is rotatably attached about an axis 10 to an upper end of a leg 9 rotatably attached to an automobile floor 4 about an axis 8.

Thus, when the seat back 2 is tilted forward, the rear seat 1 moves forward and the seat cushion 3 sinks downward, and is folded as shown by the phantom line in FIG. A space for storing luggage can be created on the upper part of 2.

A seat belt (not shown) is provided on the above-mentioned rear seat 1 in order to ensure the safety of the seated occupant.
And a seat belt buckle 11 for stopping a belt latch (not shown) of the seat belt is arranged on the side of the rear seat 1.

The seat belt buckle 11 is attached to the tip of an arm 12 having self-supporting property, and the lower end of the arm 12 is attached to the automobile floor 4 so as to be rotatable about a shaft 13. The seat belt buckle 11 is shown in FIGS.
As shown in FIG. 4, it is arranged between the recesses 14 and 15 formed in both the seat back 2 and the seat cushion 3 which form the rear seat 1, and when the seat back 2 is folded, By being pushed by the rear surface 16 of the formed recess 14 and pivoting around the shaft 13, the stored state shown in FIG. 3 or 4 is obtained. Further, when the seat back 2 is erected in a use state, the seat belt buckle 11 is rotated about the shaft 13 by being pushed by the lower surface 17 of the recess 15 formed in the seat cushion 3 that is lifted upward, as shown in FIG. It will automatically stand up in the usage state shown.

In the rear seat 1 configured as described above, as the seat back 2 is moved from the use position to the folding position, the seat belt buckle 11 is automatically put in the retracted state, and conversely from the folding position. As the seat back 2 is raised in the use position, the seat belt buckle 11 is automatically raised in the use state. Therefore, the seatbelt buckle 11 is stored and erected without bothering the occupant, reducing the burden on the occupant, and the seatbelt buckle 11 damages the skin of the seatback 2 or the seat cushion 3 during folding. Will disappear.

In the embodiment, as shown in FIG. 4, the lower surface 17 of the recess 15 for pushing the seat belt buckle 11 is integrally formed with the protective cover 18 of the bracket 6 fixed to the rear portion of the seat cushion 3. The structure is
Similar to the seat back 2 side, a structure in which the seat back 2 is incorporated may be used.

[0018]

According to the structure of the rear seat according to the present invention, since the seat belt buckle provided in the rear seat is automatically stored and erected, the burden on the occupant is reduced.

Further, in the present invention, since the seat belt buckle is automatically stored when the seat back is folded, the seat belt buckle does not damage the skin of the seat back or the seat cushion.
