It covers so that a, 65b, and 65c may be covered. Then, the positioning protrusion 76 of the sheet type switching mechanism 74 is moved inward to the position shown by the alternate long and two short dashes line in FIG. 7B. That is, with the distance between the positioning protrusions 76 narrowed, the positioning protrusions 76 are projected forward from the inside of the seat cover 11 through the through holes 11b provided in the upper portion of the seat cover 11. Then, each of the three arms 65a, 65b, 6
The lower arm 65b of 5c is displaced downward to the pad-permissible position, and the seat cover 11 is pushed out from the inside.

On the other hand, the cushion pad 12 is supported by the support piece 81 and the support bar 83 of the cushion pad holding mechanism 80, like the cushion pad 2 in the covering work of the type A seat cover 1 (see FIG. 22). .

In this state, when the cylinder 63 is contracted, the slide base 62 moves forward, and the cushion pad 12
The upper portion of the seat enters the arm group 73 surrounded by the three arms 65a, 65b, and 65c while retracting the seat cover 11. Then, the seat cover 11 is reversed and covered from the upper portion of the cushion pad 12. Then, when the upper part of the cushion pad 12 is slightly covered, the movable bar 111 of the second connecting member guide mechanism 110 is pulled by the cylinder 113 and pivots from the stored position to the advanced position (see FIG. 13). Then, the lifting plate 117 provided at the tip of the movable bar 111.
Will be located on the connecting wire 14 provided on the contact surface portion 11a with the cushion pad 12, which is the surface portion of the seat cover 11 turned upside down. In addition, cylinder 1
16 extends and the lift plate 117 descends, the hook 124 engages the connecting wire 14 from above the mounting cotton cloth 13, and when the wire engagement sensor 126 detects the presence of the connecting wire 14, the cylinder 125 operates to connect. The wire 14 is the receiving plate 1
Attracted to 19.

When the connecting wire 14 is pulled onto the receiving plate 119, the sensor switch 121 is moved to the connecting wire 14
Is detected, the connecting wire 14 is clamped by the clamp claw 120. Further, the movable bar 111 slightly rotates in the storage position direction, and the elevating plate 117 descends to cause the connecting wire 14 to move into the groove portion 12 of the cushion pad 12.
Guided in c. At this time, the front end of the stopper 114 is rotated upward by the cylinder 115 to move the movable bar 11
1 is stopped so as not to rotate too much in the storage position direction.

Subsequently, similarly to the work of covering the type A seat cover 1, the connecting metal fitting clamping device 30 causes the connecting receiving wire 15 to be exposed in the groove 2c of the cushion pad 2,
That is, the connecting wire 14 and the connecting receiving wire 15 descend to the contact position, and the connecting wire 14 and the connecting receiving wire 15 are sandwiched and connected by the C ring 38 by the hog ringer 36 (see FIG. 23).

After this, the second connecting member guide mechanism 110 and the connecting metal fitting clamping device 30 return to their original state, and the slide base 62 moves further forward, so that the cushion pad 12 enters the arm group 73. (See FIG. 24). Then, when the cushion pad 12 completely enters the arm group 73 and the cushion pad 12 is covered by the seat cover 11, the slide base 62 returns to its original state, and the covered seat cover 11 moves the seat carrying mechanism 40. By the table 21
It is carried up (see FIG. 25).

The covers 1, 11 can be covered. Therefore, no human work is required, and the productivity can be improved.

Further, by making the arm 65c displaceable between the cover mounting position and the pad permissible position, even the seat covers 1 and 11, which are slightly smaller than the cushion pads 2 and 12, can be easily attached to the arm group 73. When the seat covers 1, 11 are covered with the cushion pads 2, 12, the cushion pads 2, 12 can be covered.
Are closely attached by the seat covers 1 and 11. Therefore,
The seat covers 1 and 11 look good without wrinkling.

When the cushion pads 2 and 12 are inserted into the arm group 73, the positioning protrusions 76 are provided in the headrest mounting holes 2a and 12a of the cushion pads 2 and 12 through the through holes 1b and 11b of the seat covers 1 and 11. By inserting the through holes 1 of the seat covers 1 and 11
b, 11b and the headrest mounting holes 2a, 12a are surely aligned with each other, and when covering, the seat covers 1, 11
It is possible to prevent the coating from slipping off. further,
By providing the seat type switching mechanism 74, even if different types of seats are used, the seat cover 1,
Since 11 can be mounted, there is no need to provide a seat cover mounting device for each type, which is economically very advantageous.
