Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD This invention relates to improvements in vehicle seats.

[Prior Art and Problems] A conventional vehicle seat 101 was formed to be slidable in the longitudinal direction of the vehicle, as shown in FIG. This was designed taking into consideration the sitting height, height, etc. of the driver or passengers.

However, with these designs, there is a limit to the slide length of the vehicle, and one occupant must enter the vehicle and sit on the seat.

In a vehicle in which a plurality of seats are formed in the vehicle, the sliding length of each seat is inevitably short, and the space between the seat and the vehicle becomes narrow, making it difficult to sit.

This was especially inconvenient for women wearing Japanese clothes and the physically disabled.

In the former case, the hem and sleeves of the Japanese clothes got caught in the vehicle and became torn or dirty.

In the latter case, it is not only difficult for a person to enter the vehicle, but also the assistance of several people is required to enter the vehicle and take a seat. It was difficult for several people to fit into the narrow vehicle at once, so it was extremely difficult to help them.

[Means for Solving the Problems] Accordingly, in the present invention, the vehicle seat is configured to be movable toward the door of the vehicle using a slide device.

[Function] The vehicle seat is moved toward the door and outside the door to seat the occupant outside the door, and then the vehicle seat is moved inside the vehicle again to store the occupant inside the vehicle. be.

[Example] Figs. 1 and 2 show plan views of a vehicle 1 for explaining the basic principle of the present invention.

In the figure, 2 is the floor, 13, 4, 5, 6 are the doors, 7.8.
9.10 is a vehicle seat, and each vehicle seat 7 to lO is connected to the floor-2 via a slide device 11.12.13.14.
It is installed in

The slide devices 11 to 14 are formed to move toward the door, and as the slide devices 11 to 14 move toward the door, the vehicle seats 7 to 10 move toward the doors 3 to 6.
The basic structure is such that it can be carried out of the vehicle 1 by being opened, and the passenger can be seated in this state.

Next, a specific example of the slide device used in the present invention will be described.

m3 [N is the slide device 15 formed with the seat rail 17 and the floor rail 16 as basic components 0. FIG. 4 is a sectional view taken along the line AA in FIG. 3.

The floor rail 16 has slide flanges 18 formed on the left and right sides, and a front bracket 19 and a rear bracket l=
It is fixed to the floor of the vehicle via 20.

A seat frame 22 on which a vehicle seat 21 is mounted is attached to the floor-rail 16, and the guide groove 24 of the guide block 23 is fitted into the slide flange 18, so that the floor-rail 16 is slidably attached to the floor-rail 16.

The rack 39.39 and the gear 32.32 are meshed with each other, and as the gear 32.32 rotates in the direction of the dashed arrow, the rack 39.39, that is, the seat fixing frame 33, rotates in the direction of the solid arrow. You can go back and forth freely.

At the lower corner of the seat fixing frame 33, rollers 40, 40 are provided to facilitate reciprocating movement.

The seat fixing frame 33 directly or indirectly connects the center bins 38, 38 to the F section of the gear 32, 32 (auxiliary play) 41
and the guide plate 31, the gear 32.
This is to ensure that it does not fall outside of 32.

A guide plate 3 is attached to one gear tooth portion of the gear 32.
A stopper 43 with an operating lever 42 pivotally supported at 1 is constantly engaged via a coil spring 44 to prevent the rotation of the gears 32 and 32 and to fix the movement of the seat fixing frame 33.

When the operating lever 42 is pulled, the stopper 43 is separated from the gear teeth, and the gears 32 and 32 are free to rotate, allowing the seat fixing frame 33 to reciprocate.

The seat fixing frame 33 is elastically supported by a coil spring 45.45 interposed between the guide plate 31 and the bracket 35.35.

This prevents the gears 32, 32 from coming off due to changes in the height of the racks 39, 39.

Further, according to the present invention, by controlling the door and the slide device in conjunction with each other, the door can be opened and closed and the slide device can be moved automatically.
