DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle capable of securing a living space for a seated occupant by absorbing a shock load received from a side wall of a vehicle body while suppressing lateral deformation of a seat in a side collision of the vehicle. For safety sheet.

[0002]

2. Description of the Related Art In the prior art, in general, in the event of a side collision of a vehicle, even if an impact force enters a vehicle cabin from a side wall of a vehicle body such as a door, the vehicle seat is deformed so as to be crushed in a lateral width direction, and thus the occupant space. For example, Japanese Unexamined Utility Model Publication No. 3-26652 discloses a technique that can ensure the above.

[0003] That is, a plurality of cross members extending in the vehicle width direction are provided in both the seat cushion and the seat back of the driver's seat and the passenger seat, respectively, and end portions of the cross members provided in the seat cushion and the seat back are provided. These are fixed with a connecting member extending in the vertical direction.

[0004]

However, in the prior art as disclosed in Japanese Utility Model Application Laid-Open No. 3-26652, the cross members provided in the seat cushion and the seat back are integrally fixed by a connecting member. Therefore, the tilting of the seat back with respect to the seat cushion is restricted, and the reclining operation of the seat back of the seat is not taken into consideration, so that there is a problem that the sitting comfort is impaired and the usability is not good.

The present invention has been made in view of such a conventional problem. The present invention enables a reclining operation of a seat back, improves sitting comfort, and improves usability. In the case of a side collision,
It is an object of the present invention to provide a vehicle safety seat capable of reliably transmitting the impact load to the opposite side, securing a living space for the occupant, and improving safety.

[0006]

[0007]

When a side collision of a vehicle occurs, the side wall of the vehicle body such as the door (B) which receives the impact energy enters the vehicle interior while being deformed. The side wall of the vehicle body deformed toward the interior of the vehicle collides with one side of the vehicle safety seats (10a to 10g). The impact energy received by the vehicle safety seats (10a to 10g) is first input to the reclining devices (50) arranged on both sides of the seat. Then, after the reclining device (50) is deformed and absorbs a certain amount of impact, the remaining impact energy is transferred to the reclining device (5).
0), the reinforcing members (40a, 40b, 40)
d-40 g) at one end of the load input / output unit (42a, 42b,
42d to 40g). Reinforcing member (40a, 4
0b, 40d to 40g) are seat cushions (20, 40d to 40g).
20b, 20f, 20g) and at least one of the base ends of the seat backs (30, 30d, 30e).

The reinforcing members (40a, 40b, 40d-40)
g) has a high rigidity and is installed so as to extend in the vehicle width direction, so that the vehicle safety seat (10a to 10g)

As shown in FIG. 8, the vehicle safety seat 10
In this embodiment, a is a driver's seat, and a passenger seat 70 is provided side by side on the vehicle safety seat 10a. A console 71 is provided between the vehicle safety seat 10a and the passenger seat 70. Inside the console 71, at the time of a side collision of the vehicle, a vehicle safety seat 10 is provided.
A load transmitting member (not shown) for transmitting an impact load received from the door B, which is close to one side of “a”, to the passenger seat 70 is provided therein. The load transmitting member is made of a material such as foamed aluminum, hard urethane, or honeycomb that can transmit the impact force to some extent while absorbing the impact force.

Next, the operation will be described. As shown in FIG.
When another vehicle C collides from the side and a side collision of the vehicle occurs, the bumper at the front end of the vehicle C is moved to the door B on the side wall of the vehicle body.
And the door B attempts to enter the vehicle interior while being deformed by the impact energy. The door B deformed toward the vehicle interior directly or indirectly collides with one side of the vehicle safety seat 10a beside it.

One side of the vehicle safety seat 10a is a door B
The impact energy received from the vehicle cannot be absorbed only by the reclining device 50 disposed on the side of the seat on the side of the collision, and is attached to the lower end of the back frame 31 installed in the seat back 30 via the mounting brackets 44, 44. And transmitted to the consolidated reinforcing member 40a. More specifically,
As shown in FIG. 8, the impact energy is first input to the arm member 51 of the reclining device 50. Here, the arm member 51 alone cannot absorb all impacts. That is, the arm member 51 which has received the shock absorbs the shock to some extent while being deformed so as to bend inward by the gap to the load input / output portion 42a at one end of the reinforcing member 40a located inside. Subsequently, the remaining impact energy is transmitted to the load input / output unit 42a at one end of the reinforcing member 40a.

Since the cross member 41 of the reinforcing member 40a has high rigidity and is installed so as to extend in the width direction of the seat, one side of the vehicle safety seat 10a receives one of the impact energy. The part is the seat slide device 60
From the vehicle body floor A, and the rest
1 and is transmitted to the other side of the vehicle safety seat 10a so as to be horizontally displaced as it is.

The reinforcing member 40 to which the impact energy has been transmitted.
The load input / output unit 42a at the other end of the a strikes the arm member 51 of the reclining device 50 beside it, and the reduced impact energy is further transmitted from the other side of the vehicle safety seat 10a via the console 71 to the vehicle body. It is absorbed while being dispersed on the floor A and the passenger seat 70.

At this time, since the cross member 41 of the high-rigidity reinforcing member 40a is stretched in the width direction inside the seat, the deformation is suppressed when the vehicle safety seat 10a is crushed in the width direction, and the seat is seated. This is effective in securing the living space of the occupants, and the safety of the occupants is enhanced.

The reinforcing member 40a is provided at the base end of the seat back 30 that supports the vicinity of the waist of the seated occupant so as not to interfere with the reclining device 50 and does not hinder the tilting of the seat back 30. Therefore, in the normal sitting state, the reclining operation of the seat back 30 can be sufficiently performed. As a result, the reclining operation is sufficiently considered, the usability is improved, and at the time of a side collision of the vehicle, there is an effect in securing a living space for a seated occupant, and safety can be improved.

As shown in FIGS. 11 and 12, a bar-shaped reinforcing member 40 b is directly fixed to the rear end 23 of the cushion frame 21. The reinforcing member 40b transmits an impact load received from one side of the vehicle body side wall to the other side on the opposite side in a side collision,
It is a member for preventing deformation of the seat in the width direction.

The reinforcing member 40b is formed by fixing disk-shaped load input / output portions 42b, 42b slightly larger than in the first embodiment to both ends of a cross member 41b extending in the width direction of the seat. As shown in FIG. 13, both ends of the cross member 41b extend from both sides of the seat cushion 20b, and a load input / output unit 42b is integrally fixed to the tip.
Further, the load input / output unit 42b is provided with the base member 52 and the pivot 53 of the reclining device 50 arranged on both sides of the seat.
The load input / output unit 42b is overlapped when viewed from the side.
Is slightly fixed to both ends of the cross member 41b.

As shown in FIGS. 11 and 12, frame members 24, 24 for supporting side portions swelling on both sides of the seat cushion 20b are welded to front end portions 22 on both sides of the cushion frame 21, Further, under the front end portions 22 on both sides, trim wires 25, 25 for hanging a trim cover covering the seat cushion 20b are provided.

In the present embodiment, deformation such as crushing in the width direction mainly at the rear end side of the seat cushion 20b during a side collision of the vehicle is suppressed without hindering the reclining operation of the seat back 30 by the reclining device 50. It is effective in securing a living space for a seated occupant.
