[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile equipped with a movable seat, and more particularly, in a passenger car etc., the seat and door are integrally moved in the lateral direction of the vehicle body. The present invention relates to an automobile with a movable seat that can be configured freely, thereby making it easy for even people with physical disabilities to get on and off the vehicle.

[Background of the Invention] Generally, in a passenger car, a seat on which a passenger sits is fixed to the floor of the vehicle body, while a door is attached to the vehicle body via a door hinge so that it can be opened and closed. Therefore, the occupant must open the door and sit down on the seat by crawling through the opening in the vehicle body corresponding to the door, or exit the vehicle through the opening defined in this way.

The interior of a passenger car is small, so when installing seats inside the car, emphasis is placed on ensuring that the driver does not get tired from driving for long periods of time, and that the seats are comfortable for the passengers.
Little consideration is given to getting in and out of the car.

For people with normal driving ability, there is no problem when getting in and out of a passenger car, but for example, when a person with a physical disability or illness rides in a car, for the reasons mentioned above, it may be difficult to get into the seat. It is not easy to get out of the car from the seat and often requires assistance from others.

Furthermore, it is desirable for women wearing Japanese or formal attire to be able to easily get on and off the vehicle in a comfortable posture.

[Object of the Invention] The present invention has been made in connection with the above, and provides a driving system in which a seat and a door are integrally installed on a support member that is laterally displaceable with respect to the body of a passenger car via a rail member. By displacing the support member under the driving action of the source, the door and seat are configured to protrude to the side of the vehicle body and move when getting on or off the vehicle, making it extremely easy to move without having to take an unreasonable posture. To provide an automobile with a movable seat that allows passengers to get on and off the vehicle.

[Means for Achieving the Object] In order to achieve the above object, the present invention provides a rail member installed on the floor of a vehicle body constituting a passenger car or the like so as to be oriented in the lateral direction of the vehicle body; The vehicle is characterized by comprising a support member to which the seat and the door are guided and to which the seat and door are attached and supported, and a drive source that moves the support member along the rail member via a transmission means.

[Embodiments] Next, preferred embodiments of the automobile with a movable seat according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a getting on/off mechanism according to the present invention. Here, as shown in the figure, a front seat in a four-wheeled passenger car (two-door type) will be explained as an example.

First, on the floor constituting the vehicle body 12 of a four-wheeled passenger vehicle, two sets of long rail members 1 are installed at a portion corresponding to the front seats.
4a, 14b and 16a, 16b are installed. The rail members 14a, 14b and the rail members 16a, 1
6b are installed parallel to each other so that their longitudinal directions are perpendicular to the traveling direction of the vehicle body 12, and furthermore, they are installed so as to alternately face each other across a center line passing through the center of the vehicle body 12. As can be easily understood by referring to FIG. 2, in this embodiment, these rail members 14a, 1
4b, 16a, and 16b have a substantially U-shaped cross section, and one ends of the long prismatic support members 18a, 18b and 20a, 20b are slidably fitted into each other. In this case, the support member 18
In order to improve the sliding properties of a, 18b, 20a, and 20b, it is preferable to attach a plurality of rollers (not shown) or the like to predetermined portions thereof.

On the other hand, a tri-bird seat 21 is attached and supported on the upper surface of the other end side of the support members 18a, 18b, and a front door 22 is fixed to the edge portion thereof.

Next, as shown in FIG. 1, a motor 24 is disposed at the rear of the vehicle body 12, and the driving force of the motor 24 is applied to a drum 26 attached to the rotating shaft of the motor 24.
For example, a wire 28 is wound as a means for transmitting the signal to 8a. In this case, the end 28a of the wire 28
, 28b are pulleys 30a, 30b provided on the vehicle body 12.
They are bent so as to be oriented in opposite directions through the support member 18a, and their tips are respectively attached to predetermined portions near the ends from the center of the support member 18a.

In this way, the driving action of the motor 24 is transmitted to the support member 18a via the wire 28, and due to this driving action, the driver's seat 21 and the front door 22, which are integral with the support members 18a and 18b, are moved as the vehicle body 12 moves forward. It is configured to be movable in a direction orthogonal to the direction.

Similarly, a passenger seat 32 is attached and supported on the upper surface of the other end of the support members 20a, 20b, one end of which is inserted into the rail members 16a'', 16b, and the front door 22 is attached to the edge of the passenger seat 32. The other front door 3
3 is fixed. A motor 3 is located at the rear of the vehicle body 12.
4 is arranged, and a drum 36 is connected to this motor 34.
A wire 38 is wound around. End 3 of the wire 38
8a and 38b are the pulleys 4 as in the case of the wire 28.
0a and 40b, the directions are bent in opposite directions, and the tips thereof are respectively engaged with predetermined portions of the support member 20a.

In addition, in FIG. 2, reference numerals 42.44 indicate rear seats, and these rear seats 42.44 are similar to the above-mentioned tri-bird seat 21 and passenger seat 32.
Particularly in the case of a four-door type passenger car, it goes without saying that it can be configured to be movable in the lateral direction of the vehicle body 12 integrally with a rear door (not shown). Further, in the case of a two-door type passenger car as shown in this embodiment, the rear seats 42 and 44 are configured to be movable in the front and back direction via a rail member (not shown), and the driver's seat 21 and the passenger It is also possible to rotate the position between the seat and the seat 32.

The automobile with a movable seat according to the present invention is basically constructed as described above, and its functions and effects will be explained below.

First, the case where the driver gets on the vehicle will be explained.

As shown in FIG. 2, it is assumed that the driver's seat 21 and the front door 22 are in a position protruding from the side of the vehicle body 12. It is easily understood that if the tri-bird's seat 21 is in this position, the driver can sit on the tri-bird's seat 21 very comfortably.

Therefore, in FIG. 1, the driver drives a motor 24 disposed at the rear of the vehicle body 12. That is, when the motor 24 is driven and the drum 26 connected to the motor 24 is rotated in the direction of arrow A in the figure, the end 28a of the wire 28 is wound around the drum 26. As a result, the end portion 28a displaces the support member 18a in the direction of the arrow in the figure via the pulley 30a.

On the other hand, the other end 28b of the wire 28 is pulled out as the drum 26 rotates in the direction of arrow A, and follows the displacement of the support member 18a in the direction of arrow A.

During this time, the support member 18a is guided by the rail member 14a, and the front door 22 is attached to the tri-bird seat 2, which is integrally attached to both the support member 18a and the support member 18b guided by the rail member 14b.
The front door 22 moves in the direction of the arrow, that is, in the direction in which the front door 22 closes.

When the front door 22 is closed in this manner, the driver can automatically assume the normal driving position while remaining seated in the driver's seat 21. Therefore, the drive of the motor 24 may be stopped.

Next, after driving the passenger car and stopping it, the motor 24 is driven to rotate the drum 26 in the direction of arrow B, and the driver's seat 2
1 and the front door 22 move in the direction of arrow C, the driver can easily get out of the vehicle without changing his posture while sitting. Similarly, passengers on the front passenger seat 32 can get on and off the vehicle very easily.

[Effects of the Invention] As described above, according to the present invention, the seat and the door are integrally provided on the support member, and the support member is guided by the rail member to be displaced in the lateral direction of the vehicle body under the action of the drive source. The structure is such that the seat is exposed to the outside of the vehicle body. Therefore, the occupants including the driver do not have to bend over to get in and out of the vehicle after opening and closing the door, and can easily do so while sitting in a comfortable position. Therefore, a remarkable effect can be obtained especially when a physically handicapped or sick person gets in and out of a passenger car.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
Of course, various improvements and changes in design are possible without departing from the gist of the present invention.
