Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat, and more particularly to a structure of a seat armrest.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, for example, some vehicle seats 30 are provided with armrests 32 on both sides of a seat cushion 31 thereof. Then, a person seated on the seat cushion 31 places his or her arm on the upper surface of the armrest 32 so as to achieve comfort when seated.

[0003]

By the way, in order to improve the comfort, it is better that the width of the upper surface of the armrest 32 is larger. However, armrest 3
Increasing the width of 2 leads to an increase in the lateral width of the vehicle seat 30 as a whole, and it is impossible to increase the width of the armrest 32 in a vehicle having a limited width dimension. As a result, an automobile seat 31 with sufficient comfort could not be expected.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to improve the comfort by expanding the area on which the arm of the armrest is placed without expanding the lateral width of the entire seat. The purpose of the present invention is to provide a seat that also has a function of preventing the vehicle from jumping forward when applied to an automobile seat.

[0005]

In order to solve the above-mentioned problems, the present invention extends an armrest provided on a side portion of a seat cushion upward, and the upper part of the extended armrest is bent at least toward the seat cushion side. The main point is a sheet provided with a bending member as described above.

[0006]

With the above structure, the upper portion of the armrest is bent toward the seat cushion by the bending member. as a result,
The upward facing surface of the armless bent to the seat cushion side is where the arm is placed.

On the other hand, when the bending member is used to erect the bent armrest toward the seat cushion, it is possible to sit on the seat cushion or stand from the seated state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a vehicle seat will be described below with reference to FIGS.

In FIG. 1, an automobile front seat 1
Is composed of a seat cushion 2, a backrest 3, and an armrest 4. The backrest 3 is connected to the rear surface of the seat cushion 2.

The armrests 4 are arranged on both side surfaces of the seat cushion 2, and the side portions 4a at the base end portion are further extended to form upper portions 4b. The armrest 4 and the seat cushion 2 are formed by filling the skin material with a soft pad such as sponge, and in this embodiment, the skin materials of the armrest 4 and the seat cushion 2 are sewn together to be integrated.

A frame is arranged inside the armrest 4 and the seat cushion 2. That is, a fixed frame 5 made of an iron plate having a concave cross-section is arranged at the side portion 4a of the armrest 4 and the central portion of the seat cushion 2. On the other hand, a bending frame 6 made of an iron plate is arranged at the center of the upper portion 4b of the armrest 4.

The fixed frame 5 and the bending frame 6 are connected to each other by a hinge 7. In this embodiment, the upper portions 4b of the armrests 4 on both sides are bent between the bending position (use position) bent to the seat cushion 1 side shown in FIG. 1 and the standing position (non-use position) shown in FIG. I am allowed to do it.

In this embodiment, the fixed frame 5, bending frame 6 and hinge 7 constitute a bending member. Next, the operation and the operation of the vehicle seat configured as described above will be described.

When seated on the seat 1, the upper portions 4b of the armrests 4 on both sides are raised to stand upright as shown in FIG. Therefore, since there is no obstacle above the seat cushion 2, a person can sit down. At this time, since the upper portion 4b is erected upward,
When you sit down, you can sit while holding your hand, and it becomes very easy to sit down.

When the upper portions 4b of the armrests 4 on both sides are tilted toward the seat cushion 2 while seated on the seat cushion 2, the hinges 7 bend the upper portions 4b to the use position shown in FIG. When the upper portion 4b is bent to the use position, the outer surface of the upper portion 4b faces upward. As a result, its wide outer surface is formed in front of the seated person. That is, the wide outer surface of the upper portion 4b is formed in front of the seated person as a surface sufficient for placing the arm.

Therefore, the seated person can comfortably sit on the seat 1 with his / her arms on the wide surface. Moreover, since the seated person is restrained by the upper portion 4b, it is possible to prevent the person from jumping forward due to sudden braking or the like.

Further, since the wide outer surface of the upper portion 4b is used as a surface sufficient for placing the arm, the width of the armrest 4 is increased to secure the surface sufficient for placing the arm in order to improve comfort. You don't have to. Therefore, the seat 1 is excellent in comfort without increasing the width of the automobile seat 1 having a limited width dimension.

When it is desired to stand up from the seat 1, the upper part 4b can be easily raised from the seat 1 by raising the upper part 4b to the unused position. At this time, since the upper portion 4b is erected upright, it is possible to stand up with a hand when standing up, and it becomes very easy to stand up.

The present invention is not limited to the above embodiment, but may be configured as follows within the scope of the present invention. (1) It may be applied to seats other than the automobile seat 1. (2) In the above-mentioned embodiment, the bending armrests are provided on both sides, but the invention may be embodied in a seat provided with the bending armrests. (3) The armrest may be bent outward (on the side opposite to the seat cushion). (4) As shown in FIG. 5, an operation panel 10 such as an audio device may be provided on a part of the wide outer surface of the upper portion 4b.
Therefore, by forming the panel 10, the operation of the audio or the like becomes easy. (5) In the above-described embodiment, the upper portion 4b is constituted by the hinge 7 so as to be stopped and fixed at two positions, a used position and a non-used position, but other bending members may be used. In addition, the upper portion 4 can be placed at any position between the used position and the unused position.
It may be implemented by using a bending member in which b is stopped and held.

[0020]

As described in detail above, according to the present invention, the area on which the arm of the armrest is placed can be increased and comfort can be improved without increasing the lateral width of the entire seat, and is applied to a vehicle seat. In this case, it has an excellent effect of preventing the jumping out to the front.
