Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automobile seat structure, particularly a separate type seat structure.

(Prior Art) As a conventional automobile seat, particularly a separate type seat, there is one shown in FIG. 3, for example. That is, 10 is a floor of the vehicle body, and cross members 30 and 40 are respectively fixed to the upper surface of the floor 10 in the vehicle width direction with the tunnel portion 20 in between. These cross members 30,4
0 has a pair of seats 50 and 60 in the slide section 7.
0, 80 and 90, 100, respectively, so as to be slidably supported in the longitudinal direction of the vehicle. That is, these seats 50 and 60 are installed on the floor 10 so as to be spaced apart from each other in the vehicle width direction. A console box 110 is attached to the tunnel portion 20 between the seats 50 and 60.

(Problem to be solved by the invention) However, in such a conventional automobile seat structure, the seats 50 and 60 are independently supported on the floor 10 via the sliding parts 70, 80, 90, and 100. Because of this, when a side collision occurs and force is applied to one seat through the door, the force is transmitted to the entire floor, making it impossible to disperse the force.

(Purpose of the invention) This invention was made with attention to these points, and it effectively disperses the force that enters the seat through the door etc. to the floor in the event of a side collision, and prevents the door from entering the vehicle. The purpose of the present invention is to provide an automobile seat structure that can minimize seat movement.

(Structure of the invention) In order to achieve the above-mentioned purpose, the automobile seat structure according to this invention includes a seat frame of a pair of seats fixed to the vehicle body at a distance from each other in the vehicle width direction, and a seat frame provided between these seats, with one end is fixed to the seat frame of one seat, the other end faces the seat frame of the other seat at a predetermined distance, has a predetermined strength and size, and transfers the deformation force of one seat to the other seat. A console box is provided as a reinforcing member that can be transmitted to the seat.

(Example) This invention will be explained below based on the drawings.

Figures 1 and 2 are diagrams showing an embodiment of this invention. First, to explain the configuration, 1 is a floor of a vehicle body, and a pair of seats 5 and 6 are installed on this floor 1 with a tunnel portion 2 in between, spaced apart from each other in the vehicle width direction. That is, cross members 3 and 4 extending in the vehicle width direction are fixedly installed on the floor 1 so as to sandwich the tunnel portion 2, and seat slide rails extending in the vehicle longitudinal direction are installed on each cross member 3 and 4. 12, 13 and 14, 15 are fixed, respectively.

Note that the seat slide rails 12, 13 and 14, 15 are fixed to the floor 1 of the vehicle body via cross members 3, 4, respectively, but they are fixed directly to the floor 1 of the vehicle body without providing the cross members 3, 4. It may be fixed, and there are various conventionally known fixing modes. For example, a small piece of bracket may be provided on the floor 1 and the seat slide rails 12, 13 and 14, 15 may be fixed to the bracket. In this embodiment, cross members 3 and 4 are provided as a typical example.

Seat slide rail 12, 13, 14, 15
The seat slide 1 of the pair of seats 5 and 6 is
6, 17 and 18, 19 are fitted, respectively. Therefore, these seats 5 and 6 are supported so as to be slidable in the longitudinal direction of the vehicle.
Further, the seats 5 and 6 have seat cushions 20 and 21, and seat cushions 20 and 21, respectively.
Seat bags 22, 23 rotatably supported by
20 of these seat cushions,
21 and seat backs 22, 23 have seat cushion frames 24, 25 and seat back frames 26, 27, respectively, which have a U-shaped cross section and are highly rigid. The seat slides 16, 17 and 18, 18 are fixed to the lower surfaces of seat cushion frames 24, 25, respectively. A console box 28 is a rectangular parallelepiped reinforcing member having a predetermined strength and a predetermined size. This console box 28 is located above the tunnel section 2,
It is located between the seats 5 and 6, and is firmly fixed to the side surface of the seat cushion frame 25 of one of the seats 6 by bolts 29.
It is designed to move as the slide slides. The other end faces and is close to the seat frame of the other seat 5 at a predetermined distance. The console box 28 is large enough to be used not only as a storage space but also as an armrest for the driver.

Next, the effect will be explained.

If the car was hit from the side (second
In the direction of arrow A in the figure), the impact force pushes and bends a door (not shown) and is applied to the seat 5. That is, it is applied to the seat cushion frame 24 directly or via the seat back frame 26. As a result, part of the impact force is supported by the cross member 3 and floor 1 via the seat cushion frame 24, seat slides 16, 17, and seat slide rails 12, 13 of the seat 5, and the remaining impact force is transmitted to the seat 5
The seat cushion frame 24 and seat back frame 26 of the vehicle are distorted toward the inside of the vehicle. As a result, the remaining impact force is applied to the console box 28 as the seat back frame 26 or the seat cushion frame 24 comes into contact with the console box 28, which is a reinforcing member. At this time, since the console box 28 has sufficient strength, it will not be damaged, and since it is fixed to the other seat, the impact force can be easily transferred to the seat cushion frame 25 and seat back of the other seat 6. The transmission is reliably transmitted to the frame 27.

That is, since the reinforcing member is a box, it has high rigidity and has a wide surface, so force is effectively transmitted and the impact force from the seat cushion frame 24 or the seat back frame 27 is reduced. can be reliably transmitted to other members. The impact force transmitted to the other seat 6 in this way is transmitted to the cushion 4 and the floor 1 through the seat cushion frame 25, seat slides 18, 19, and seat slide rails 14, 15.
Supported by Therefore, all of the impact force is distributed and supported on the floor 1, and the seat 5
Distortion and deformation of the door (not shown) can be minimized and intrusion through the door (not shown) can be prevented.

Note that even when an impact force is applied from the side of the other seat 6, the impact force is similarly dispersed and supported by the floor 1, and the distortion and deformation of the seat 6 is suppressed to a minimum. In addition, even if you slide the seat back and forth, the sides of the console box, which is a reinforcing member, are large, so
Can receive shocks reliably.

In the above embodiment, the seat slide rail is fixed to the vehicle body via a cross member, but as mentioned above, in the case where the seat slide rail is fixed to the vehicle body via a bracket, for example, the cross member is involved in transmitting the impact force. , but the same effect can be obtained. Furthermore, it goes without saying that similar effects can be obtained even in a structure in which the cross member is disposed on the back side of the floor.

In this embodiment, the reinforcing member is fixed to the seat cushion frame, but it can also be fixed to the seat back frame.

(Effects of the invention) As explained above, according to the invention, the seat frame of a pair of seats fixed to the vehicle body at a distance from each other in the vehicle width direction, and the seat frame provided between these seats, one end of which is a console box as a reinforcing member that faces the seat frame of the seat at a predetermined distance, has a predetermined strength and size, and is capable of transmitting the deformation force of one of the seats to the other seat; Since it is equipped with
Even if an impact force is applied to the seat from the side of the car body through the door due to an impact collision, etc., this force is not received by only one seat, and support is distributed to the floor via the other seat, and the seat is supported in the width direction of the seat. It is possible to minimize the movement of the vehicle, eliminate the fear of it coming off the floor, and minimize distortion of the passenger compartment.

Furthermore, since the console box is used as a reinforcing member, it is possible to improve the utilization rate of the interior of the vehicle and to maintain a comfortable posture for the occupants, thereby reducing fatigue, especially during long-distance driving.
