Description

[Detailed description of the invention] (Field of industrial application) This invention is an armrest of a vehicle seat such as a bus passenger seat. The present invention relates to an improvement in an armrest for a vehicle seat in which a stepped stopper portion is provided at the upper end of the support member to maintain the use state of the arm by abutting the base end of the arm.

(Prior art and its problems) As shown in Fig. 4, a support member b is fixed to the side surface of a seat A, and an arm a is attached to the support member b from the state shown by the solid line. The armrest rotatably supported in the non-use state as shown in FIG. It can be used as an armrest.

By the way, this stopper portion 1 is located on the front side of the seat. The arm a is generally used when the user is seated on the seat by rotating it from the non-use state to the use state as shown by the two-dot chain line in FIG. Therefore, when rotating arm a from the state shown in FIG. 5 to the state shown in FIG.
There is a risk that a fingertip, a part of clothing, etc. may be caught between the base end 2 of the arm a and the stepped stopper portion 1 of the support member b. In the figure, reference numeral 3 indicates a shaft on which the arm a is rotatably attached to the support member b. Note that the lower end surface 5 of the arm a is locked to the upper end rear surface 5 of the support member b, thereby restricting the arm a from falling backward.

(Problems to be Solved by the Present Invention) Therefore, the present invention has been proposed to prevent fingertips, clothes, etc. from being caught between the proximal end of the arm and the stepped stopper portion of the support member when the arm is rotated to the use state. The purpose is to ensure that there are no

(Means to be Solved by the Present Invention) In order to achieve the above object, the armrest of the vehicle seat of the present invention has a cut groove formed in the stepped stopper portion, and the cut groove connects the base end of the arm with the arm rest of the vehicle seat of the present invention. The stepped stopper portion prevents the fingertips etc. from being pinched. That is, even if a fingertip or the like is inserted between the base end of the arm and the support member, it is prevented from moving into the cut groove and being pinched.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

In the drawings, the same reference numerals as in FIGS. 3 and 4 indicate the same members, and their explanations will be omitted.

FIG. 1 shows an unused state, that is, a state indicated by a two-dot chain line in FIG. In this case, a kerf 12 is bored.

At the upper end of the support member b, side walls b1 and b2 protrude in a bifurcated manner, and the base end 2 of the arm b is interposed between the left and right side walls b1 and b2, and is rotatable in the front and rear directions by a shaft 3. It is attached to the shaft. Stepped stopper portions 11, 1 to which a portion of the base end 2 of the arm b is locked on the inside of one or both of the left and right side walls b1, b2.
1 is provided, and when the base end of arm a abuts against these stopper parts 11, 11, arm a
is in a state of use, which is a substantially horizontal state (FIG. 2).

Therefore, the base end 2 of the arm a is the stopper part 11,
11, since the cut groove 12 is arranged between the left and right stopper parts 11, 11,
Most of the base end 2 of arm a does not contact the support member b side. Therefore, the article is not held between the arm a and the support member b.

Note that the depth and shape of the kerf 12 are arbitrary, and the shape of the kerf 12' as shown in FIG. 3 is also arbitrary.

(Effects) As mentioned above, the present invention has an extremely simple structure because it is sufficient to simply provide a cut groove in the conventional stepped stopper part. The arm and the support member do not pinch the fingertips or clothes of the seated person, and safety is improved compared to the conventional products.
