Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement in the storage structure of an open roof for automobiles.

(Prior art and its problems) Conventionally, for example, a convertible car with a hard roof has been proposed in which, when the roof is opened, the open roof is stored in a storage space set behind the seat back of the rear seat. .

By the way, in the above-mentioned cars, when the roof is open, the rear seats are automatically retracted so that the open roof can be smoothly stored in the storage space, and when the roof is closed, the rear seats are automatically moved to improve seating comfort. It is convenient to be moved back to .

(Purpose of the invention) This invention was made in response to the above-mentioned request, and its purpose is to automatically move the entire rear seat to a predetermined position in conjunction with the opening and closing operations of the hard roof. It is something.

(Structure of the invention) For this reason, the present invention provides a vehicle with an open roof stored in a storage space set behind the seat back of the rear seat. The vehicle is characterized by being provided with an interlocking mechanism that moves the seat cushion diagonally upward and forward when the roof is closed, and moves the seat cushion diagonally downward and rearward when the roof is closed.

(Effects of the invention) According to the invention, the interlocking mechanism automatically moves the entire rear seat away from the roof stowing trajectory in conjunction with the roof opening operation, and automatically moves the entire rear seat out of the roof in conjunction with the roof closing operation. Since the roof is moved back to the retracted locus, the open roof can be retracted smoothly when the roof is opened.

In addition, when the roof is closed, the rear seat is returned diagonally downward to the rear, ensuring sufficient head and leg space for those seated in the rear seat, resulting in good seating comfort. Even when the seat is evacuated, sufficient head space and leg space are secured for the seated person, resulting in good seating comfort.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The embodiment shown in FIG. 1 is a convertible car 2 equipped with a hard roof 1, in which the entire rear seat 3 is retracted diagonally upward and forward in conjunction with the opening operation of the hard roof 1 (see the two-dot chain line in FIG. 1). Rear seat 3 is linked to the closing operation of hard roof 1.
The entire body is moved back diagonally downward (see the solid line in Figure 1).

When the hard roof 1 is closed, the first
As shown by the solid line in the figure, the front end 1a is removably connected to the upper end 2b of the front windshield 2a, and the rear end 1b is removably connected to the upper surface of the rear panel 2c.

As shown in FIG. 6, when the hard roof 1 is opened by the motor 70 and the link 71, as shown by the two-dot chain line in FIG.
The front end 1a is swung upwards with the rear end 1b as the center (), and then, while the front end 1a side is folded in half inward, the rear end 1b is slid downward (), and the seat back of the rear seat 3 is 3
It will be stored in the storage space 4 set behind a.

Note that 5 is a front seat, and 6 is a partition panel that partitions the storage space 4 and the rear trunk space 7.

As shown in FIG. 2, the rear seat 3 is composed of a seat back 3a and a seat cushion 3b, and the seat back 3a is connected to the seat cushion 3b via a reclining mechanism 8 so as to be tiltable forward.

A rectangular seat cushion frame 9 is provided below the seat cushion 3b of the rear seat 3, and the left side of the seat cushion frame 9,
The front and rear end portions of inverted U-shaped side members 10, 10 extending in the front-rear direction are fixed to the right position, respectively, and the front portions of each side member 10, 10 have
As shown in FIG. 3 only on the right side, the support hole 10a
There is a guide hole 1 in the rear facing diagonally upward.
0b is cleared.

On the other hand, as shown in FIGS. 3 to 5, on the protrusion 12a of the vehicle floor 12, U-shaped bases 13, 13 that extend in the front and rear direction and face each side member 10 are bolted. - They are fixed with nuts 14, 14, respectively.

A hole 13a for supporting both ends of the main shaft 15 extending in the vehicle width direction is formed in the front part of each of the bases 13, 13, and a hole 13b for supporting the gear box 16 is formed in the intermediate part. , holes 13c for supporting guide pins 17 are formed at the rear.

Link levers 19, 19 are fixed to the main shaft 15, which is supported in the front hole 13a of each base 13, 13 and prevented from coming off with a cotter pin 18, and the upper end of each link lever 19 will be described later. Upper end attachment part 2 of the screw shaft 20 of each gearbox 16
Along with 0a, the support hole 10 of the side member 10
a by a pin 21.

A drive motor 2 is installed between each of the bases 13, 13.
wire cables 23, 2 extending in the vehicle width direction from the output shafts at both ends of the drive motor 22;
Worms 24, 24 in each of the gearboxes 16, 16 are connected to the gearbox 3.

A worm 2 is installed in each gear box 23, 23.
A worm wheel 25 meshing with 4 is provided,
Internal thread 2 formed on each worm wheel 25
The screw shaft 20 is screwed into the screw shaft 6 so as to be able to reciprocate vertically.

The guide pins 17, 17 of the rear holes 13c of the respective bases 13, 13 are attached to the side members 10, 10.
The guide holes 10b of each side member 1 are connected to each other.
Supports the rear part of 0,10.

With the above configuration, if the hard roof 1 is currently closed, the screw shaft 20 is moved back downward, so the entire rear seat 3 is returned to the rear diagonally downward direction ( The solid line in Figure 1,
(See the two-dot chain line in Figure 4). In this state, sufficient head space and leg space are secured for the person sitting on the rear seat 3, so seating comfort is good.

Next, when the roof opening/closing switch 72 provided on the dash board or the like is opened, the drive motor 2
2 is rotated in the forward direction, and the worms 24, 24 of the gearboxes 16, 16 are
24 is rotated, and the worm wheels 25, 25 are rotated by the worms 24, 24, so that the screw shaft 2
0 and 20 move back upwards.

As a result, the front part of the side members 10, 10,
In other words, the front part of the rear seat 3 is lifted obliquely forward and upward, and following this, the rear part of the side members 10, 10 whose guide holes 10b, 10b are guided by the guide pins 17, 17 of the bases 13, 13, that is, the rear seat The rear part of the seat 3 is also lifted diagonally upward and forward, and the entire rear seat 3 is retracted diagonally upward and forward (see the two-dot chain line in FIG. 1 and the solid line in FIG. 4).

As a result, the storage space 4 behind the rear seat 3 is expanded.

Thereafter, as described above, the motor 70 is driven by the control signal from the control box 73, and the hard roof 1 is swung ( ) and slid ( ) and stored in the storage space 4 .
The rear seat 3 is retracted obliquely forward and upward from the storage locus of the hard roof 1, and the storage space 4 is expanded, so that the hard roof 1 can be stored smoothly.

Furthermore, since the rear seat 3 is moved obliquely forward and upward, even in this state, sufficient head space and leg space are secured for the person sitting on the rear seat 3, and seating comfort is good.

On the other hand, when the roof is closed, if the roof opening/closing switch 72 is opened, the hard roof 1 is reversely slid () in the reverse procedure to that described above.
The rear seat 3 is swung in the opposite direction ( ) and set to the roof position, and then the drive motor 22 is reversely rotated to move the rear seat 3 to the roof position.
The entire body is returned diagonally downward to the rear (see the solid line in FIG. 1 and the two-dot chain line in FIG. 4).

Note that the hard roof 1 may be retracted or set at the same time as the rear seat 3 is retracted or returned.

Further, the rear seat 3 can also be moved back and forth using a manual switch 74.
