FIG. 1 is a side view of a roof structure of an automobile to which an operating device according to an embodiment of the present invention is applied. In FIG. 1, reference numeral 1 indicates a vehicle body of the automobile, and reference numeral 2 indicates a front header above a front window 3. The roof extends rearward from 4 to the rear body 5 and covers the passenger compartment 6. This roof 2
It is formed of a hard member made of a steel plate or the like, and is divided into two parts in the front-rear direction of the vehicle body: a roof front part 7 that covers the front part 6a of the passenger compartment and a roof rear part 8 that covers the rear part 6b of the passenger compartment. The conventional roof rear portion 8 includes a rear window 9.

The roof front portion 7 is provided with a vehicle-body-side mounting portion (hereinafter, simply referred to as mounting portion) 10 having a substantially inverted U shape as a whole, and lower end portions 11a of both leg portions 11 of the mounting portion 10 are It extends slightly obliquely downward and forward from the pelt line 12 of the vehicle body 1. As shown in FIG. 6, the both leg portions 11 are pivoted to the front edge 13a located inside the rear edge 14a of the side door 14 of the inner panel 13 inside the rear fender F at the lower end portion 11a. It is pivotally attached by a wearing pin 15. In addition, this mounting part 1
0 may omit the part which extends across the roof 2 and may be constituted only by the leg portions 11.

On the other hand, vehicle-body-side mounting portions (hereinafter simply referred to as mounting portions) 16 that extend forward below the belt line 12 are provided at lower end portions on both sides of the roof rear portion 8. The mounting portion 16 is pivotally attached by a pivot pin 17 of the inner panel 13 at its tip portion 16a.

The roof front portion 7 and the roof rear portion 8 constituting the roof 2 are rotated about the pivot pins 15 and 17 so that they can take the closed position shown in FIG. 1 and the open position shown in FIG. It has become. At this open position, the roof front part 7 and the roof rear part 8 are housed in a housing part at the rear part of the vehicle compartment in a state of being overlapped with each other in the front-rear direction. The roof front portion 7 and the roof rear portion 8 are shown by solid lines in FIG. 3 between the closed position and the open position, as will be described later in detail.
Rotate as indicated by the one-dot chain line and the two-dot chain line.

The roof front portion 7 and the roof rear portion 8 can be operated between the closed position and the open position by the drive mechanism 20 shown in FIG. The drive mechanism 20 includes a drive gear 21.
Are driven to rotate by an electric motor 23 via a double worm mechanism 22. When the roof 2 is in the closed position shown in FIG. 1, a drive arm 24 extending obliquely forward and upward from the drive gear 21 is fixed to the drive gear 21 at its lower end. Lower end portion 1 of mounting portion 10
A pivot pin 11c is also provided at a position above the pivot pin 15 of the connecting arm 11b fixed to 1a and extending upward. A first link 26 is attached to the pivot pin 11c at its upper end, and the lower end of the first link 26 is pivotally attached to the upper end of the drive arm 24 by a pivot pin 25. On the other hand, a pivot pin 27 is provided at a position rearward of the pivot pin 17 of the mounting portion 16 for the roof rear portion 8. A second link 28 is attached to the pivot pin 27.
Is pivoted at its upper end and this second link 2
Similarly to the first link 26, the lower end 8 is pivotally attached to the upper end of the drive arm 24 by a pivot pin 25.

As shown in FIGS. 6 and 7, the mounting portion 16, the first and second links 26, 28 drive arm 24.
Etc. are arranged between the rear fender F and the inner panel 13, the mounting portion 10 is arranged inside the inner panel 13, and the connecting arm 11b is the inner panel 13.
Extends across. In addition, in FIG. 6 and FIG. 7, reference symbol G indicates a windshield.

In the closed position of the roof 2, the first link 26 is
As shown in detail in FIG. 5, it extends substantially in line with the drive arm 24 and at a slight angle with respect to the leg 11. Therefore, even if the motor 23 is driven and the drive arm 24 rotates in the direction of arrow A so as to open the roof 2, the drive arm 24 moves the first arm 26 through the first link 26 at the beginning of this rotation. The operation of the legs 11 is extremely small. Therefore, the operation of the roof front portion 7 is small at the initial stage of this rotation. On the other hand, the second link 28 is arranged so as to extend in a direction substantially perpendicular to the drive arm 24 at the roof closed position. Therefore, when the motor 23 is driven as described above, the arrow of the drive arm 24 is provided. At the initial stage of the rotation in the A direction, the mounting portion 16 is rotated relatively largely around the pivot pin 17. Therefore, the roof rear portion 8 is largely operated in the initial stage of the above rotation. In this way, at the beginning of the opening operation of the roof 2, the roof rear portion 8 starts to operate quickly and largely, and the roof front portion 7 operates to continue small, so that the opening operation of the roof can be performed smoothly. .

On the other hand, as shown in FIG. 8, the second link 28 extends at a slight angle with respect to the drive arm 24 in the open position of the roof 2. Therefore, the motor 23 is driven and the drive arm 24 closes the roof 2 by the arrow B.
Even if the mounting portion 16 is rotated in the direction, the actuation of the mounting portion 16 via the second link 28 by the drive arm 24 becomes small in the initial stage of this rotation. Therefore, the operation of the roof rear portion 8 is small at the initial stage of this rotation. On the other hand, the first link 2
6 is the drive arm 24 in this roof open position.
It is arranged so as to extend in a direction substantially perpendicular to, and therefore, when the motor 23 is driven as described above, it largely operates at the initial stage of the rotation of the drive arm 24 in the direction of the arrow B. Therefore, the roof front part 7 is largely operated in the initial stage of the above rotation. As described above, in the closing operation of the roof 2, the roof front part 7 starts to operate quickly and largely, the roof rear part 8 starts to operate smaller to follow, and the roof front part 7 is completely positioned at the closed position. After that, since the roof rear portion 8 is rotated to the closed position, the closing operation of the roof can be smoothly performed.

The operations of the roof front portion 7 and the roof rear portion 8 described above are shown in FIGS. 3 and 4. In these figures, the state in which the roof front portion 7 opens is F-closed, F-1, F-
2, F-3, F-open, and the state in which the roof rear portion 8 opens is shown by R-closed, R-1, R-2, R-3, R-opened.

When the roof 2 is stored in the rear part of the vehicle compartment, that is, in the back part of the rear seat 30, the seat back 3 of the rear seat 30 is stored.
1 is tilted forward as shown by the chain double-dashed line in FIG.

A mechanism for automatically returning the seat back 31 from the forward tilted position to the normal position when the roof 2 is moved from the open position to the closed position is provided behind the seat back 31. This mechanism comprises a link mechanism 40 as shown in FIG. This link mechanism 40 is on the floor F
The pivoting pin 4 at the base on the bracket 41 fixed to the
It has an L-shaped lever 43 pivotally attached by 2.
A first rod 44 that extends in a substantially horizontal direction is pivotally attached to the lower end of the lever 43 at the rear end. The front end of the first rod 44 has a seat back 31.
Is pivotally attached to the support bracket 31a. A second end extending in a substantially vertical direction is provided at the horizontal end of the lever 43.
A rod 45 is pivotally attached at its lower end.

Near the front edge of the rear deck D, the rear end is the rear deck D.
An operating lever 47 pivotally attached to a bracket 46 attached to the lower surface of the is provided. The upper end of the second rod 45 is pivotally attached to a substantially middle portion of the operating lever 47. On the other hand, an abutting member 48 extending rearward from the rear lower end portion of the roof rear portion 8 is attached. A roof mounting portion 49 is provided below the seat back 31 of the rear seat 30.

In the mechanism for returning the seat back 31 of the rear seat 30 to the normal position, the contact member 48 is moved from the position shown in FIG. 11 to the contact member 48 as shown in FIG. 9 during the operation of the roof 2 from the open position to the closed position. The operation lever 47 is rotated clockwise, whereby the seat back 31 is automatically returned to the normal position from the forward tilted position via the link mechanism 40. Further, when the roof 2 is operated from the closed position to the open position, the roof 2 is mounted on the roof mounting portion 49 as shown in FIG.

As described above, according to the present invention, when the roof is opened and closed, the seat back automatically returns to the normal position, and the operability is improved.

Further, in the above-described embodiment of the present invention, the roof front portion and the roof rear portion which form the roof formed of the hard member are pivotally attached to the vehicle body through the vehicle body mounting portions, respectively, so that these roof front portions are provided. It is possible to take one of the roof forming position, that is, the closed position and the storage position, that is, the open position. Therefore, unlike the conventional case where the roof panel has to be completely separated from the vehicle body for storage, the roof installation or storage work can be performed in a short time by a simple operation. Further, in the present invention, since the entire roof is formed of the hard member as described above, the appearance is desired, and vibration noise does not occur even when receiving wind. Further, since the roof front and the roof rear are at least partially overlapped with each other in the open position when they are stored, the storage space can be made relatively small.
