DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure related to a seat device and a vehicle body in an automobile, and more particularly, to seats disposed in a vehicle cabin of a vehicle body and positions adjacent to the seats in the vehicle width direction. And a side wall of a vehicle body having a door opening.

[0002]

2. Description of the Related Art Conventionally, the following structure has been proposed as a related structure between a seat device and a vehicle body in an automobile.

[0003] That is, the vehicle body has a vehicle cabin floor constituting a lower portion thereof, and a pair of side walls constituting respective outer portions of the vehicle body and extending upward from respective side portions of the vehicle cabin floor. Front and rear seat devices are provided in a vehicle room surrounded by the vehicle room floor and both side walls. The front seat device includes a driver seat and an assistant seat provided adjacent to each other in the vehicle width direction, and the driver seat is supported so as to be movable in the vehicle body longitudinal direction with respect to a vehicle cabin floor.

[0004] Of the two side walls, a driver door opening is formed on the side wall on the driver seat side in the width direction of the vehicle body in proximity to the driver seat, while the assistant side is formed on the side wall on the assistant seat side. A passenger door opening is formed near the seat in the vehicle width direction. A steering shaft protruding rearward and upward from the front lower portion of the driver seat toward the driver seat is provided, and a handle supported by a protruding end of the steering shaft is provided.

A rear door opening is formed on each of the side walls so as to approach the rear seat device in the vehicle width direction, and a rear door is provided before each of the door openings can be opened and closed. .

The driver can get on and off the passenger compartment through the driver door opening, and can operate the steering wheel by sitting on the driver seat by getting on the driver's seat. Thereby, driving of the automobile becomes possible.

[0007]

However, the above-mentioned conventional technology has the following problems.

That is, for example, a driver attempts to place a load on the rear seat device from outside the vehicle outside the driver's seat or to seat a child on the rear seat device. (Hereinafter referred to as “work on the rear seat device”), first, the rear door opening is opened by operating the rear door,
After performing the above-mentioned “work on the rear seat device”, again, the operation to the rear door closes the rear door opening,
Next, the driver's door opening is opened by operating the front door, the driver gets on the vehicle and sits on the driver's seat, and the driver's door opening is closed again by operating the front door.

However, as described above, when the driver performs "work on the rear seat device", the driver operates the front door to open and close the driver door opening, and rides through the driver door opening. In addition to this, it is necessary to operate the rear door to open and close the rear door opening, and therefore, the "work on the rear seat device" is complicated for the driver.

Therefore, it is conceivable that the above-mentioned “work on the rear seat device” is performed only through the driver door opening without operating the rear door.

However, since the driver door opening is close to the driver seat in the vehicle width direction and the opening area of the driver door opening is small, the above-mentioned "operation for the rear seat device" is also required. Is complicated.

On the other hand, the driver door opening is formed so as to have a larger opening area, and through this driver door opening, getting on and off and "working on the rear seat device" can both be easily performed. Conceivable.

However, if the opening area of the driver door opening is simply made larger, the strength of the side wall on the driver seat side tends to be lower than the strength of the side wall on the passenger seat side. This causes the strengths to be unbalanced with each other, which is not preferable in terms of the strength of the vehicle body.

Further, if the driver's seat is rotated forward and downward to a forwardly inclined position and the driver's seat is largely moved forward, the rear part of the driver door opening is provided. The fact that the side is close to the driver's seat in the vehicle width direction is eliminated, and the substantial opening area on the rear side of the driver's door opening is increased. It is thought that it becomes easy to do.

In the above case, however, if the driver simply moves the driver's seat forward by tilting the seat back forward, the driver's seat will abruptly collide with the steering wheel. May cause unnecessary external force.

For this reason, it is necessary to pay attention to the arrangement position of the steering wheel in the operation for tilting the seat back forward or moving the seat back forward with respect to the driver's seat.
It is not easy to smoothly perform the above-mentioned “work on the rear seat device”.

The present invention has been made in view of the above-mentioned circumstances, and is an operation of placing a load on the rear seat device from outside the vehicle outside the driver's seat. The task is to make it easy for the driver to perform this task.

Further, the above-mentioned "work on the rear sheet device"
However, even if it is made easier for the driver,
An object of the present invention is to maintain the strength of both side walls of a vehicle body evenly.

Further, the above-mentioned "work on the rear sheet device"
It is an object of the present invention to make it possible to prevent unnecessary external force from being applied to a handle located in front of a driver's seat constituting a front seat device, thereby facilitating the work.

Therefore, the substantial opening area on the rear side of the driver door opening becomes larger, and the “work on the rear seat device” through the driver door opening can be more easily performed.

Next, the driver seat is moved rearward through the driver door opening and returned to the original position. Then, a driver who gets in through the driver door opening can be seated on the driver seat. After seating, if the driver's door opening is closed by operating the front door,
Driving of the automobile is enabled.

Therefore, when performing "work on the rear seat device" from outside the vehicle outside the driver's seat, conventionally, the front and rear two doors provided on the side wall on the driver's seat side are operated respectively. However, according to the present invention, the above operation is sufficient by operating the front door, so that this operation can be easily performed by the driver.

According to a second aspect of the present invention, a rear door opening is formed only on a side wall of the side wall on which the assistant door opening is formed, in a width direction of the vehicle, close to the rear seat device. The following effects occur.

That is, as described above, if the rear opening edge of the driver door opening is made to be behind the rear opening edge of the assistant door opening, the opening area of the driver door opening becomes larger. The strength of the side wall on the driver seat side tends to be lower than the strength of the side wall on the passenger seat side.

However, as described above, the rear door opening is formed on the side wall on the passenger seat side in the vicinity of the rear side of the passenger door opening, whereas the side wall on the driver seat side is formed on the side wall on the driver seat side. Since there is no other door opening close to the rear of the driver door opening, even if the opening area of the driver door opening is slightly increased, the imbalance in the strength of the left and right side walls is prevented.

Thus, as described above, while the "work on the rear seat device" can be easily performed, the strength of the left and right side walls of the vehicle body is maintained more evenly, which is beneficial in the strength of the vehicle body.

Further, as described above, the rear opening edge of the driver door opening is located behind the rear opening edge of the assistant door opening, in other words, the rear opening edge of the assistant door opening. Is located forward of the rear opening edge of the driver's door opening. For this reason, the front opening edge of the rear door opening located behind the assistant door opening can be located further forward without being disturbed by the rear opening edge of the assistant door opening. That is, the front side of the rear door opening can be closer to the rear side of the driver door opening in the longitudinal direction of the vehicle body.

Therefore, for example, the driver and the assistant cooperate with each other from the outside of the driver's seat and the outside of the rear seat device, which is the outside of the passenger seat, to the left and right. When performing the above “work on the rear seat device”, as described above, since the rear side of the driver door opening and the front side of the rear door opening approach each other in the front-rear direction, the driving operation through these openings is performed. The "work on the rear seat device" by cooperation between the person and the assistant becomes extremely easy.

According to a third aspect of the present invention, a rear door is provided so as to open and close the rear door opening freely, and the rear door can be freely moved forward and backward along the outer surface of the side wall.

For this reason, when the rear door is moved forward and the rear door opening is opened, it is assumed that a rotatable door having a hinge at the front end is provided for opening and closing the rear door opening. In comparison, the rear door is farther away from the front of the rear door opening behind, so that the front of the rear door opening is opened more widely.

Therefore, the “work on the rear seat device” through the cooperation of the driver and the assistant through the two openings can be further facilitated.

According to a fourth aspect of the present invention, a rear door is provided so as to open and close the rear door opening freely, and the front side of the rear door is rotatable forward and backward toward the outside of the vehicle body. The rear end of the rear door is pivotally supported on the rear edge of the rear door opening.

For this reason, when the rear door is reciprocated to open the rear door opening, it is supposed that the rear door opening is opened and closed by the front opening edge of the rear door opening. As compared with a case where the rear door is pivotally supported by a hinge, the rear door is largely apart from the front part of the rear door opening to the outside, so that the front part of the rear door is opened more widely.

Moreover, the rear door is hinged to the rear opening edge of the rear door opening by a hinge. Therefore, a hinge for pivoting the rear door is not attached to the front opening edge. The front and rear widths of the center pillar, which is a part of the vehicle body that constitutes the space between the assistant door opening and the rear door opening, can be reduced by eliminating the need for setting a mounting surface for the vehicle.

Accordingly, the front opening edge of the rear door opening can be positioned more frontward, and the opening area of the front portion of the rear door opening can be further increased.
Therefore, the “work on the rear seat device” through the cooperation of the driver and the assistant through the openings can be further facilitated.

According to a fifth aspect of the present invention, the rear end of the driver door opening and the front end of the rear door opening are overlapped in a side view of the vehicle body.

For this reason, when performing the “work on the rear seat device” in cooperation with the driver and the assistant, the driver and the assistant can work closer to each other in the front-rear direction. , More easily.

According to a sixth aspect of the present invention, the driver seat is
A seat cushion supported on the vehicle cabin floor so as to be movable in the longitudinal direction of the vehicle body, and protruding upward from a rear end side of the seat cushion, and capable of forward and backward rotation forward and downward. In a related structure between a seat device and a vehicle body in an automobile having a seat back pivotally supported at a rear end portion of the seat cushion,

When the seat back rotates forward and the seat back assumes a "forward tilting posture" having substantially the same inclination as that of the handle, a forward inclination preventing means for preventing further forward rotation is provided. It is provided.

For this reason, when the above-mentioned “work on the rear seat device” is to be performed, the seat back is set to the “forward tilt posture” in an attempt to increase the substantial opening area on the rear side of the driver door opening. When the seat back inadvertently collides with the handle,
This is prevented by the forward lean preventing means.

Therefore, at the time of the "work on the rear seat device", unnecessary external force is prevented from being applied to the handle without paying attention to the presence of the handle, so that the work can be performed smoothly.

[0110] The invention according to claim 7 is characterized in that when the driver seat is moved forward until the seat back in the "forward leaning position" reaches the vicinity of the steering wheel, the driver seat is further moved forward. There is provided a movement inhibiting means for inhibiting the movement to the side.

For this reason, when the above-mentioned “work on the rear seat device” is to be performed, the seat back is largely moved forward to increase the substantial opening area on the rear side of the driver door opening. Sometimes, this seat back inadvertently collides with the handle,
It is prevented by the above-mentioned movement inhibiting means.

Therefore, at the time of the "work on the rear seat apparatus", unnecessary external force is prevented from being applied to the handle without paying attention to the existence of the handle, and thus the work can be performed smoothly.
