DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the accompanying drawings, FIG.
The accessory equipment of the side portion of the seat shown in FIG. 2 is exemplified in a walk-through type vehicle in which the armrest A is provided as a plate shape on the side portion of the seat S as shown in FIG. The armrest A is provided on the side portion of the seat cushion C and is provided with a rising bracket 1, which is provided at front and rear portions with a space therebetween.
It is assembled and arranged within the interval of 2. Each of the rising brackets 1 and 2 is installed in a standing manner by fixing the lower side to the side portion of the seat cushion C. Further, the armrest A is provided so as to be movable along a guide groove 3 provided in the rising brackets 1 and 2 as shown in FIG.

The armrest A is formed so that the width L _{1 in the} direction of both sides substantially corresponds to the distance L ₂ between the rising brackets 1 and ₂ . The armrest A includes a cushion pad assembled to an undercover and covered with a skin material, and is formed as a plate-shaped body having a thickness W ₂ substantially the same as the width W ₁ of the rising brackets ₁ and ₂ . Also,
When this armrest A moves along the guide groove 3,
It is attached by setting the position so that one end side is in contact with the side part of the seat back B.

The armrest A is provided with support members 4 and 5 arranged in two sets on both sides near one end (only one side is shown). Each of the supporting members 4 and 5 is equipped so as to move the armrest A along the guide groove 3 by being assembled in the guide groove 3 of the rising brackets 1 and 2. The support members 4 and 5 are metal rod-shaped support shaft portions 40 and 50, and ring members 41 and 51 made of synthetic resin having a sliding property such as nylon and fitted and fixed on the axes of the support shaft portions 40 and 50. Is formed into a substantially cylindrical shape. Moreover, as each support member 4, 5, at least each support shaft portion 40, 50
Equipped with different shaft diameters. As a specific example, the support shaft portion 50 of the support member 5 has a larger shaft diameter than the support shaft portion 40 of the support member 4.

Each of the rising brackets 1 and 2 is formed of a metal base plate 10 and a synthetic resin cover plate 11 into a box shape having a hollow cross section. The rising brackets 1 and 2 are assembled by holding a space between a member plate 12 fixed to a side portion of the seat cushion C and a center cover 13 covering the member plate 12.

The rising brackets 1 and 2 have respective plate surfaces facing the both sides of the armrest A, that is, the base plate 1
The above-described guide groove 3 is provided continuously in the vertical direction by cutting out the plate surface of 0 in a slit shape. The guide groove 3 raises the armrest A to the rising bracket 1,
It is formed in a predetermined length and shape so that the posture can be changed from the vertical position to the horizontal direction on the upper side within the interval of 2.

As shown in FIG. 3, the guide groove 3 has a predetermined width and is continuous in the longitudinal direction, and is formed by bifurcating the upper side. Further, the guide groove 3 is formed by inclining the intermediate groove portion 33 extending from the lower vertical straight groove portion 32 toward the branch point between the vertical stop portion 30 and the horizontal stop portion 31 obliquely upward.

Of the two forks on the upper side, the seat back B
One side 30 located on the side closer to is formed as a vertical stop portion that is curved upward in the vertical direction. The other is formed as a horizontal stop portion 31 which is curved in a horizontal direction from a position substantially parallel to the upper end side of the vertical stop portion 30. As shown in FIG. 4, the vertical and horizontal stop portions 30, 31 have a large groove width from the branch point in accordance with the shaft diameters of the support shaft portions 40, 50.
It is formed by making a mistake. The supporting members 4 and 5 are attached to the bracket plates P forming the base frame of the armrest A as shown in FIG.
It is installed in.

In the auxiliary equipment of the side portion of the seat configured as described above, the armrests A of the upright brackets 1 and 2 are normally positioned because the supporting members 4 and 5 are located below the vertical straight groove portions 32 of the guide groove 3. It is stored upright in the vertical direction on the side of the seat within the space. At the standing storage position, the thickness W _{2 of the} armrest A is increased by the rising bracket 1,
Since the width W ₁ is formed to be approximately the same as the width W ₁ , it is accommodated so as not to overhang to the side of the seat.

When using the armrest A, the entire armrest A is lifted vertically upward. When the armrest A is lifted, the supporting member 5 is located on the upper side, the supporting member 4 is located on the lower side, and the supporting member 4 slides vertically in a vertical combination. 32
Therefore, it can move stably along the inclined groove portion 33. Further, since the intermediate groove portion 33 is inclined obliquely upward, the supporting members 4 and 5 are smoothly moved and guided toward the branch points of the vertical and horizontal stop portions 30 and 31.

The armrest A slightly tilts as it rises and is pushed outward by contacting one side portion with the side portion of the seat back B. At the same time, the support shaft portion 50 of the support member 5 moves upward while being pressed against the outer edge of the intermediate groove portion 33, and thus enters the lateral stop portion 31.

When the supporting member 5 moves to the lateral stop portion 31 of the guide groove 3, the supporting member 5 serves as a fulcrum, and finally the supporting shaft portion 40 of the supporting member 4 moves to the vertical stop portion 30 of the guide groove 3. Are arranged in parallel with the supporting member 5 in the horizontal direction.
When the supporting members 4 and 5 are slid, the support shaft portion 4
0, 50 is a synthetic resin ring member 41 having a slip property,
Since it is covered with 51, it is possible to smoothly slide and move along the guide groove 3 without generating an abnormal noise such as a metallic scraping noise.

When the supporting members 4 and 5 are arranged in parallel in the horizontal direction,
The armrest A is located horizontally over the upper side in the space between the rising brackets 1 and 2. At the laterally extended position, the support shaft portions 40, 5 of the support members 4, 5 are provided.
0 at intervals, the vertical and horizontal stop portions 30 of the guide groove 3,
Since the armrests A are engaged and supported by 31, the armrests A can be stably cantilevered by the rising brackets 1 and 2 by being supported at two points by using the support shaft portions 40 and 50 of the support members 4 and 5 as fulcrums. .

When the armrest A is moved laterally in the horizontal direction, the diameters of the support shaft portions 40 and 50 of the support members 4 and 5 and the groove widths of the vertical and horizontal stop portions 30 and 31 are positioned on the upper side in the vertical direction. Since the member 5 side is formed larger than the supporting member 4 side, the supporting member 5 cannot enter the vertical stop 30 of the supporting member 4. Therefore, the support shaft portion 40 of the support member 4 and the support shaft portion 50 of the support member 5 can be reliably slide-guided from the branch point of the guide groove 3 to the vertical stop portion 30 and the horizontal stop portion 31, respectively.

When the armrest A is to be stored in the seat side portion from the laterally extended position, the armrest A is lifted upward from the front side of the extended position as shown in FIG. With the lifting, the support shaft portion 50 of the support member 5 moves the lateral stop portion 31.
The support shaft portion 40 of the support member 4 slides along the curved shape of the vertical stop portion 30 and is moved downward from the branch point of the guide groove 3 in the engagement position inside. When the support shaft portion 40 of the support member 4 moves downward from the branch point of the guide groove 3, the support shaft portion 50 of the support member 5 disengages from the horizontal stop portion 31 and moves downward together in the vertical and vertical directions. Therefore, the armrest A can be erected and stored in the original position on the side of the seat.

In addition to the above-mentioned embodiment, the supporting members 4, 5
It is advisable to equip the ring members 41 and 51 as rollers so that the slide guide can be carried out more stably. When the ring members 41 and 51 are rollers, the rising flange portions 34 that slidably support the rollers on their peripheral surfaces may be provided inside the rising brackets 1 and 2. Although the armrest A is described as a plate-shaped body in the above-described embodiments, any other substantially rectangular plate-shaped body such as a cradle and a shelf plate may be provided as an accessory equipment on the side of the seat. it can.
