    Next, a method of using the sheet releasing jig 40 configured as described above and an operation of the sheet releasing jig 40 will be described.

    FIG. 8 is a perspective view showing a usage state of the sheet releasing jig 40. As shown in FIG. 8, when the engagement state between the seat cushion 11 and the base 10 is released, the insertion plates 81A and 81B and the insertion plates 52A and 52B of the seat release jig 40 are inserted into the seat cushion 11 and the base 10. Insert between.

    Since the insertion plates 81A, 81B, 52A, 52B are sandwiched between the seat cushion 11 and the base 10, the insertion plates 81A, 81B and the insertion plates 52A, 52B are closed, as shown in FIG. Are separated from each other.

    Then, for example, the operator 5 places the thumb 65 and the base ball portion 66 on the gripping portion 58, and hangs at least one of the index finger 61, the middle finger 62, the ring finger 63 and the little finger 64 on the gripping portion 50. When pressed, the link shaft 43 rotates around the joint 54 and approaches the base material 41.

    9 is a side view of the sheet release jig 40 showing the state where the link shaft 43 is close to the base material 41, and FIGS. 10 and 11 are perspective views of the sheet release jig 40 in the state shown in FIG. is there. As shown in FIGS. 9 to 11, when the link shaft 43 moves around the support portion 42 and moves closer to the base material 41, the slider 49 moves in the slide hole 72. Thereby, the link plate 44 connected to the link shaft 43 rotates around the joint 55 without interfering with the link shaft 43.

    Since the slider 49 is provided at a position closer to the joint 55 than the grip portion 58 of the link shaft 43, the pressing force from the operator 5 applied to the grip portion 58 as a power point is the slider 49 that is the point of action. And amplified to the rear end of the link plate 44 and transmitted.

    Then, the rear end portion of the link plate 44 connected to the slider 49 also approaches the base material 41, and the front end portion of the link plate 44 moves upward.

    The distance between the front end portion of the link plate 44 and the joint 55 is shorter than the distance between the rear end portion of the link plate 44 and the joint 55.

    For this reason, the rear end portion of the link plate 44 serves as a power point, the front end portion of the link plate 44 serves as an action point, and the pressing force applied to the rear end portion of the link plate 44 is amplified to the front end portion of the link plate 44. Communicated. For this reason, the link shaft 45 connected to the tip of the link plate 44 is pulled up with a large force.

    Here, as shown in FIG. 12, the lower end portion of the link shaft 45 is connected to the slider 76, and the slide hole 74 extends in the vertical direction and is curved in an arc shape. For this reason, as shown in FIG. 13, when the link shaft 45 is pulled up by the link plate 44 rotating around the joint 55, the link shaft 45 is smoothly displaced right above.

    Since the insertion portion 47 is fixed to the link shaft 45, the insertion portion 47 also moves upward. Thus, in the sheet release jig 40, as shown in FIG. 9, the double link mechanism constituted by the link shaft 43, the link plate 44, the link shaft 45, the slider 49, the support portion 42 and the joint 55 is used for the work. The insertion portion 47 can be raised with a force larger than the pressing force applied to the grip portion 58 by the person 5.

    14 is a cross-sectional view showing a state where the insertion plates 81A and 81B and the insertion plates 52A and 52B are inserted between the seat cushion 11 and the base 10, and FIG. 15 is a view when viewed from the XV direction shown in FIG. It is a top view.

    Here, as shown in FIG. 15, the insertion plates 81A, 81B, 52A, and 52B are arranged so that the engagement clips 24 and the engagement pins 22 are positioned in the recesses 82 and 53 of the insertion plates 81A, 81B, 52A, and 52B. Insert. As shown in FIG. 14, the insertion plates 52 </ b> A and 52 </ b> B are disposed on the cross frame 15 of the seat frame 14.

    In this state, as shown in FIG. 6, the operator 5 hangs at least one of the index finger 61, the middle finger 62, the ring finger 63, and the little finger 64 on the grip portion 50, and at least one of the thumb 65 or the mother ball portion 66. When the grip portion 58 is pushed, the insertion plates 81A and 81B are displaced upward, and the seat cushion 11 is pulled up.

    At this time, the pressing force applied to the seat cushion 11 from the insertion plates 81A and 81B is applied to the cushion frame 21 with the cushion body 20 interposed therebetween. Since the upper surfaces of the insertion plates 81 </ b> A and 81 </ b> B are formed in a flat surface shape, it is possible to prevent a large load from being applied locally to the cushion frame 21 and to prevent the cushion frame 21 from being deformed.

    Then, when the seat cushion 11 is pulled up directly, the engagement state between the engagement pin 22 and the engagement clip 24 is released as shown in FIG. Here, since the insertion plates 81A and 81B are raised by a force larger than the pressing force applied by the operator 5 to the sheet release jig 40, the force applied by the operator 5 to the grip portion 58 is a relatively small force. Moreover, the engagement state by the engagement pin 22 can be cancelled | released, and the work burden of the operator 5 can be restrained small.

    Similarly, the engagement state between the seat cushion 11 and the base 10 can be released by releasing the engagement state by the engagement clip 25 using the seat release jig 40, and as shown in FIG. Can be removed from the base 10.

    In this way, by using the seat release jig 40, it is not necessary to put the hand under the seat cushion 11 and pull the seat cushion 11 upward while the operator 5 is in the middle waist. The work burden can be greatly reduced.

    Furthermore, in the process of removing the seat cushion 11 upward with the seat release jig 40, the insertion plates 52A and 52B are not displaced, and the insertion plates 52A and 52B can be prevented from damaging the base 10.

    Further, since the displacement direction of the insertion plates 81A and 81B is the upward direction and away from the battery 4, the insertion plates 81A and 81B do not come into contact with the battery 4 and the battery 4 is not damaged.

    Thus, by using the seat release jig 40 according to the present embodiment, the work load of the work of removing the seat cushion 11 performed in a narrow space can be greatly reduced without damaging the rear seat 2. it can.

    It should be understood that the embodiment disclosed this time is illustrative in all respects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
