Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat with an armrest device, which can be stored in a gusset portion of a seat back to secure a wide space when the armrest is not used.

[0002]

2. Description of the Related Art In recent automobile seats, armrest devices for armrests have been widely used for the purpose of ensuring a more comfortable posture for passengers. This armrest device generally has a structure in which the armrest body is rotatably attached to the side sill of the seat back, and when not used as an armrest, the armrest body is pivoted so as to flip up the seat. It is placed so that it fits alongside the side gusset on the back, and is designed so that it does not get in the way.

However, recently, due to the diversification of the purpose of use of automobiles and the like, it is desired to further expand the interior space of the vehicle,
Especially in the case of a type called a walk-through method that allows you to go back and forth between the front and rear seats through the center gap, the armrest body that is attached to the side sill of the seat back interferes with the walk-through. There was a problem.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned conventional problems, and a comfortable posture can be secured by the armrest, and when the armrest is not used, the inside of the sill portion of the seat back is The present invention has been completed for the purpose of providing a vehicle seat with an armrest device that can be buried and stored in a vehicle to secure a wide space and facilitate walk-through.

[0005]

A vehicle seat with an armrest device according to the present invention made to solve the above problems is an automobile with an armrest device in which an armrest body is rotatably attached to a side sill of a seat back. In the seat for use, a recess for accommodating the armrest body is formed in the side face gusset portion of the seat back,
As the rotary shaft of the armrest body is expandable and contractible,
It is characterized in that the armrest body can be stored in the recess when not in use.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. In the drawings, 1 is an armrest body, 2 is a rotation shaft of the armrest body 1, and the armrest body 1 is rotatably attached to a side face gusset portion 10 a of a seatback 10. It is basically the same as the automobile seat with armrest device.

In the present invention, the seat back 10 is provided.
A recess 11 for accommodating the armrest body 1 is formed in the side face gusset portion 10a, and the rotary shaft 2 of the armrest body 1 is extendable and retractable so that the armrest body 1 can be accommodated in the recess 11 when not in use. Is configured. With this configuration,
When the armrest body 1 is not used, the armrest body 1 is completely buried and housed in the recess 11 to expand the space inside the vehicle and particularly to facilitate walkthrough.

In the figure, the rotary shaft 2 has a knock pin type structure, and the rotary shaft 2 is supported by a support member 3 fixed to the seat back frame 12 and built in the support member 3. By the elastic force of the spring and the lock mechanism, when the armrest body 1 is pushed into the concave portion 11, the armrest body 1 is fixed in a state of being buried (indicated by the solid line in FIG. 1), and when the armrest body 1 is pushed again, it is pushed out by the elastic force of the spring. The seat back 10 is configured so as to pop out to the outside of the side face gusset portion 10a (indicated by a chain line in FIG. 1).

Further, as shown in FIG.
It is also possible that the recess 1 on the inside of the vehicle is used to store the armrest body 1 and the recess 11 on the door side is used to store the airbag unit 20, assuming that 1 is formed on the left and right side face gusset portions 10a. In this case, since the left and right seat backs 10 have the same shape, the parts can be shared, which is preferable.

As shown in FIG. 2, the thus constructed device is similar to the conventional armrest device in that the armrest body 1 is pivoted horizontally to be used as an armrest as required. Further, in the present invention, a concave portion 11 for accommodating the armrest body 1 is formed in the side face gusset portion 10a of the seat back 10, and the rotary shaft 2 of the armrest body 1 is made expandable and contractable, so that the armrest body 1 is made unfit. Since the armrest body 1 is configured to be stored in the recess 11 when used, the armrest body 1 is completely buried and stored in the recess 11. As a result, the space inside the vehicle can be further expanded and excellent usability can be achieved, and particularly during walk-through, the armrest body 1 can easily pass without obstructing as in the conventional case.

[0011]

As is apparent from the above description, according to the present invention, a comfortable posture can be ensured by the armrest, and when the armrest is not used, the armrest can be buried in the seat back and stored in a wide space. And the walkthrough can be facilitated. Therefore, the present invention is extremely useful as an automobile seat with an armrest device that eliminates the conventional problems and contributes to the industrial development.
