Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an armrest for a vehicle seat.

(Prior Art) Conventionally, as described in Japanese Utility Model Application Publication No. 58-144459, a backrest seat of a vehicle seat is provided with a seat that can be freely rotated from a horizontal armrest position to an upright position by a left-right axis. In the one in which the armrest is pivoted, the left-right axis is supported and fixed to a front-back axis fixed to the back seat, and the armrest in the upright position is rotated around the front-back axis to move the back seat to the back seat. An armrest for a vehicle seat configured to be horizontally retractable at a rear position is known.

(Problems to be Solved by the Invention) In the known method, the armrest in the upright position is supported and fixed to a longitudinal axis fixed to the backrest seat.
Since it is rotated around the longitudinal axis and stored horizontally at the rear surface of the back seat, there is a problem that when it is stored, it is far away and cannot be reached.

(Means for Solving the Problem) Therefore, the present invention pivots an armrest 4 on the side of the backrest seat 2 of the vehicle seat 1 so as to be rotatable from the horizontal armrest position to the upright position by the left-right axis η. In this case, the left-right axis η is a vertical axis 1 fixed to the back seat 2.
The armrest of the vehicle seat is configured such that the armrest 4 in the upright position can be rotated around the vertical axis 18 while in the upright position and stored upright at the rear position of the backrest seat 2. It is.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 indicates a vehicle seat, 2 a backrest seat, 3 a seat seat, and 4 an armrest. It is set so that it protrudes.

Reference numeral 5 designates an armrest frame of the armrest 4, which is formed into a mouth shape when viewed from the front, is surrounded by a cushioning material, and the surface of the cushioning material is covered with a skin.

Insertion holes 8.9 are formed in the rear portions of the side plates 6.7 of the armrest frame 5, respectively, and the outer ends of the shaft tubes 10 in the left and right direction are fixed inside the insertion holes 8 of the side plates 6. The shaft tube 10 is formed of a cylinder, and the front side of the inner end of the shaft tube 10 is cut out to form an engaging protrusion 11 . 12 and 13 are engagement surfaces of the engagement protrusion 11.

Reference numeral 14 denotes a skeleton frame of the back seat 2, which is formed by a hollow vibrator. The front end portions of mounting brackets 15 in the front-rear direction are fixed to desired positions on the left and right sides of the skeleton frame 14.

The mounting bracket 15 is formed of a vertical plate, and a rear end portion of the mounting bracket 15 projects from the rear surface of the backrest seat 2, and a vertical vertical shaft cylinder 16 is fixed to the projection portion. The vertical shaft 18 of the rotating arm 17 is inserted into the vertical shaft cylinder 16 from above, and the bolt 19 is screwed onto the lower end of the vertical shaft 18 to attach it rotatably. , horizontal section redundancy is installed consecutively.

The horizontal portion 20 is formed in a "shaped" shape when viewed from above. The horizontal portion 20 rotates about the vertical axis 18 .

The upper edge of the mounting plate 21, which projects downward, is fixed to the lower surface of the horizontal portion. The base of the left-right axis n is fixed to the mounting plate 21.

A locking protrusion n is formed at the base of the left-right axis B, and an engagement surface 24, δ, with which the engagement surface 13 engages, is formed on the engagement protrusion B.

The engagement surface 24 of the engagement projection B and the engagement surface 12 and the engagement surface 13 of the engagement projection 11 of the shaft tube 10 of the armrest frame 5 are alternately aligned with the engagement surface 24 of the engagement projection B and the engagement surface 13 of the shaft tube 10 of the armrest frame 5. The left and right axis η is aligned with the armrest frame 5 so as to engage with the armrest frame 5.
A skewer is passed through the insertion hole 8 of the side plate 6 and the insertion hole 9 of the side plate 7, and the port 3 is screwed and attached to the outer end of the left-right axis η.

Therefore, the armrest 4 is rotatable about the left-right axis η from a horizontal armrest position to a substantially vertical standing position, and the engagement surface 12 of the engagement protrusion 11 is the engagement surface of the engagement protrusion B. 24, the armrest 4 is held in the horizontal armrest position, and when the engagement surface 13 of the engagement protrusion 11 engages the engagement surface δ of the engagement protrusion B, the armrest frame 5 is prevented from rotating. control and maintain a standing position.

Then, when the armrest 4 is horizontally rotated by the rotating arm 17 while in the upright position, the armrest 4 is rotated around the vertical axis 18 while in the upright position and moved to the rear position of the backstroke seat 2 so that it can be stored upright. can be done.

This position can be reached by slightly extending your hand from the front seat, so it can be easily returned to its original position.

(effect) Next, we will discuss the effect.

The present invention has the above-mentioned configuration, and since the armrest 4 is rotatably mounted around the left-right axis η between a substantially horizontal armrest position and a substantially vertical standing position, the armrest 4 is normally placed in a horizontal armrest position. Set it to H and use it as an armrest.

Thus, the armrest 4 is attached to the rotating arm 17, and the rotating arm 17 is attached horizontally rotatably by the vertical shaft 18 pivoted to the vertical cylinder 16 of the mounting bracket 15. The armrest 4 that has been rotated can be horizontally rotated from the standing position to the rear. Therefore, the backstroke seat 2 can be moved from the upright position to the rear surface and stored.

Therefore, even in the stored state, a relatively large space is formed between the front and rear vehicle seats.

In addition, since the armrest 4 is located on the side of the standing position and on the rear side of the backstroke seat 2, even a person sitting in the front seat can easily reach the armrest 4 when it is stored. It can be used as

(Effect) ゛ Conventionally, as described in Japanese Utility Model Application Publication No. 58-144459, an armrest is provided on the side of the backrest seat of a vehicle seat so as to be rotatable from a horizontal armrest position to a standing position by a left-right axis. The left-right axis is supported and fixed to the front-back axis fixed to the backstroke seat, and the armrest in the upright position is rotated around the front-back axis to change the position on the rear surface of the backstroke seat. An armrest for a vehicle seat configured to be horizontally retractable is known.

However, in the known method, the armrest in the upright position is supported and fixed to a longitudinal axis fixed to the backstroke seat, and is horizontally stored at the rear position of the backstroke seat by rotating around the longitudinal axis. Because of this, there was a problem that when it was retracted, it was far away and I couldn't reach it.

However, in the present invention, an armrest 4 is pivotally attached to the side of a backrest seat 2 of a vehicle seat 1 so as to be rotatable from a horizontal armrest position to an upright position by a left-right axis η. The armrest 4 is supported and fixed to a vertical shaft 18 which is fixed to the backrest seat 2, and the armrest 4 in the upright position is rotated around the vertical shaft 18 while in the upright position to stand up and retract to the rear position of the backrest seat 2. The armrest 4 is attached to a rotating arm 17, and the rotating arm 17 is attached to a vertical shaft that is pivoted to the vertical shaft cylinder 16 of the mounting bracket 15. 1
8, the armrest 4 is mounted so as to be horizontally rotatable, so that the armrest 4, which has been rotated to the upright position, can be horizontally rotated to the side of the upright position, to the rear, and stored.

Since the armrest 4 is located on the side of the standing position and on the rear surface of the backstroke seat 2, even a person sitting in the front seat can easily return the stored armrest 4 to its original position and use it as an armrest.

C. The backstroke seat 2 can be retracted from the upright position on the rear surface, and even in the retracted state, a relatively large space is formed between the front and rear vehicle seats.

2. A large load is applied to the backstroke seat 2, and the backstroke seat 2
Even if the armrest 4 is bent and deformed, the cushioning properties of the backstroke seat 2 are not affected at all because the armrest 4 is retracted from the standing position.

E. Since the armrest 4 is retracted from the standing position, the cushioning properties surrounding the armrest frame can be increased, and the armrest 4 can be formed to have good cushioning properties.

This effect is achieved.
