Then, as shown in FIG. 7A, the conveyor 2
The front end of the seat receiving portion 43 protruding from the lower side of the seat holding member 41 is inserted between the seat cushion Wa and the seat back Wb of the seat W conveyed in a tilted state by the support plate 42 on the seat back Wb. The sheet protector 44 provided in the
Clamp the upper sheet W.

Following this clamping operation, the sheet W clamped by the upward swinging bias of the first swing arm 15 by the balancer 13 is lifted to a predetermined height, and
The cylinder 60 is extended to push the upper portion of the sheet holding member 41 with respect to the swing support member 31 so as to be separated from the swing support member 31, and the seat holding member 41 is biaxially attached via the sheet holding portion mounting bracket 57. As shown in FIG. 6, the sheet holding member 41 is rotated by rotating 56.
Is tilted, the clamped sheet W is erected as shown in FIG. 7B, and is held in a normal posture.

Subsequently, the first swing arm 15 is vertically swung, and the base swing mechanism 12 and the intermediate swing mechanism 16 horizontally swing the first swing arm 15 and the second swing arm 17 to assemble them. The seat W clamped on the right side of the door opening Bb of the vehicle body B conveyed by the line is moved,
In addition, the leading end rotation mechanism 16 positions the seat W in parallel with the vehicle body B via the clamp means 20.

Then, as shown in FIG. 7 (c), the clamped seat W is lowered and one of the leg portions Wd and We provided opposite the lower side of the seat W from the door opening Bb,
For example, the leg portion Wd is carried into the passenger compartment Ba. In this state, the side shell Bc disposed at the lower edge of the door opening Bb is disposed outside the roof end portion Bd in the vehicle width direction, and the distance between the leg portions Wd and We is determined by the width of the seat pillow Wc. The large size prevents the seat pillow Wc from coming into contact with the roof end Bd.

Next, the seat W is tilted and the seat pillow Wc is carried into the vehicle compartment Ba from below the roof end Wd as shown in FIG. 7 (d). When the operator tilts the sheet W, the sheet W is tilted by interposing the sheet holding member 41, the sheet holding portion mounting bracket 57, the second shaft member 56, the side plate 53, and the like via the sheet holding member 41 that clamps the sheet W. The first shaft member 5 in which the rocking support member 31 connected by the above is supported by the bearing portion 51 provided at the lower end of the base portion 21.

2 The front plate 33 of the swing support member 31 against the attraction of the permanent magnet 28 provided on the first stopper 25 formed on the upper surface of the swing support member 31.
The first shaft member 55, which is easily separated and serves as the swing center axis, is disposed near the lower ends of the swing support member 31 and the sheet holding member 41, so that the swing support member 31 and the sheet holding member 41 swing. Since the combined center of gravity G of the seat W is extremely close to the swing center axis, the seat W can be easily tilted with a slight force.

Subsequently, when the seat W is tilted, the base end rotation mechanism 12 and the intermediate rotation mechanism 16 horizontally swing the first and second swing arms 15 and 17 to move the seat W as shown in FIG. Is moved horizontally and carried into the vehicle compartment Ba. The horizontal movement of the seat W avoids the interference that occurs with the roof end portion Bd of the vehicle body because the second swing arm 17 has the detour portion 17e formed by bending.

After the sheet W is carried in to a predetermined position in the passenger compartment Ba, the sheet W is erected so that the sheet holding member 41
The swing support member 31 swings around the first shaft member 55 by the bearing portion 51 supported by the lower end of the base portion 21 via the bolt 25c of the first stopper 25 provided on the base portion 21.
The side edge 33b of the front plate 33 of the swing support member 31 is brought into contact with the top of the swing support member 31 to stop the swing, and is attracted to the permanent magnet 28 provided on the first stopper 25 to be held at the reference position. .

Therefore, the seat W is maintained in the normal posture shown in FIG. 7 (f), and the seat W is seated at a predetermined position on the vehicle body floor Be by adjusting the parallel movement and the downward movement of the seat W, whereby the passenger compartment Ba of the seat W is seated. Carrying in is completed.

The vertical movement operation associated with the loading of the seat W into the vehicle interior Wa is extremely labor intensive due to the function of the balancer 13, and the swing support central member 31 swings the swing rotation central axis. Since the sheet holding member 41 and the composite center of gravity G of the sheet W are arranged close to each other, the tilting and standing operations of the sheet W are extremely easy to perform, and the permanent magnet 28 attracts the sheet W to a normal posture. Since the structure is maintained, the structure is simple and the operation is simplified, and the work for carrying in the seat in the vehicle can be remarkably easy and safe.

The working means for removing the seat W from the clamp means 20 after moving the seat W into the vehicle compartment or for moving the clamp means 20 out of the vehicle compartment is the above-mentioned clamp means 20 for loading the seat W and the vehicle compartment carry-in. Since the procedure is almost the reverse of the procedure, description thereof will be omitted.

[0043]

According to the vehicle seat carrying-in device described above, the seat clamp means provided at the tip of the arm supported via the balancer is swingable to the base attached to the tip of the arm. Since the lower end is supported, the sheet holding member is provided on the swing support member, and the swing support member is held at the reference position by attraction by the permanent magnet, the tilted sheet and the normal posture can be maintained. It will be easier and laborious to carry the seat with the tilt of the seat into the passenger compartment, and the seat loading operation into the passenger compartment can be performed safely and easily, and the carrying-in operation can be simplified. It is a great contribution.
