  However, in a vehicle where the console box or floor tunnel cannot be installed between the left and right seats due to the commercial value of the vehicle, even if a structure for transmitting a side collision load is incorporated in the seat itself, the center region in the width direction of the vehicle floor from the seat The load cannot be transmitted efficiently.

  Accordingly, the present invention is intended to provide a vehicle body structure that can efficiently transmit a side collision load input to a seat to a vehicle body floor even in a vehicle in which a console box or a floor tunnel cannot be installed between left and right seats. is there.

The invention according to claim 1, which solves the above problem, is a pair of seats installed side by side on a vehicle body floor (for example, a vehicle body floor 4 in an embodiment described later) (for example, a seat in an embodiment described later). 1), the vehicle body is provided with a load transmission member (for example, a load transmission member 10 in an embodiment described later) that transmits the load input to the seat from the side of the vehicle body to the center region in the width direction of the vehicle body floor. The load transmission member includes a bottom plate (for example, a bottom plate 11 in an embodiment to be described later) fixed to the vehicle body floor between the pair of seats, and the inside of each seat from the left and right sides of the bottom plate. Left and right side plates (e.g., side plates 12 in the embodiments described later) standing along the side surface, and is opened between the left and right side plates in the longitudinal direction of the vehicle body. (E.g., passageway 14 in the embodiment), characterized in that the formation of the.
As a result, when an impact load is input to one seat from the side of the vehicle body at the time of a side collision of the vehicle and the inner side surface of the seat comes into contact with the side plate of the load transmission member, the load transmission member fixed to the vehicle body floor by the bottom plate The load can be received. Further, since a passage opened in the longitudinal direction of the vehicle body is formed between the left and right side plates, an occupant walking between the left and right seats and loading of luggage is allowed by the passage.

The invention according to claim 2 is the vehicle body structure according to claim 1, wherein the left and right side plates and the vehicle body floor are coupled to each other at the outer side of the left and right side plates and the lower position of the seat (for example, A reinforcing rib 13) according to an embodiment described later is provided.
Thereby, the fall of the left and right side plates is regulated by the strength member. Further, since each reinforcing member is located at the lower position of the seat, the passage space between the left and right side plates is not narrowed, and the reinforcing member is difficult to see from the outside.

  According to the first aspect of the present invention, the side collision load input to the seat can be received by the side plate of the load transmitting member fixed to the vehicle body floor by the bottom plate, so that a passage space between the left and right seats is secured. However, the side collision load can be efficiently transmitted to the vehicle body floor.

  According to the second aspect of the present invention, since the reinforcing member that joins the left and right side plates and the vehicle body floor is installed outside the side plates and at the lower position of the seat, the passage space between the side plates can be reduced and the appearance can be reduced. Without lowering the quality, the reinforcing member can reliably prevent the side plate from falling, and the support rigidity of the load transmitting member can be improved.

The front floor cross member 4 is a vehicle body floor fixedly installed on the upper portions of the front floor frames 2 and 2 and the front floor cross members 3A and 3B.

Each seat 1 includes a seat cushion 5 that supports the occupant's buttocks, and a seat back 6 that is connected to the rear end of the seat cushion 5 and supports the occupant's waist and chest (back). It is attached to the upper part of the vehicle body floor 4 via the seat rail 7 so as to be slidable back and forth. A seat back frame (not shown) is reinforced by a cross member extending in the vehicle width direction and a corrugated reinforcing plate on the seat back 6 of each seat 1, and an impact load is input to the seat 1 from the side of the vehicle body at the time of a side collision. When this is done, the load can be reliably transmitted inward in the vehicle width direction.
Further, a load transmission member 10 is fixedly installed in a substantially middle region between the left and right seats 1 and 1 on the vehicle body floor 4.

FIG. 3 is a view showing the load transmission member 10.
The load transmission member 10 is made of a plate-like metal material such as a steel plate, and includes a bottom plate 11 fixed to the vehicle body floor 4 between the left and right sheets 1, 1, and left and right sheets 1, 1 from the left and right sides of the bottom plate 11. Left and right side plates 12 and 12 erected upward along the inner side surface, and reinforcing ribs 13 (reinforcing members) integrally joined to the outer side surfaces (surfaces in the width direction) of the side plates 12 are provided. Yes.

  The reinforcing rib 13 has a three-dimensional structure in which a pair of right-angled triangular side walls are joined to each other at a hypotenuse corresponding portion, and a portion corresponding to the remaining one side of the right-angled triangle is welded and fixed to the outer surface of the side plate 12. Each reinforcing rib 13 is fixed to the vehicle body floor 4 at a position below the corresponding seat 1 when attached to the side plate 12. Therefore, the load transmitting member 10 is fixed to the vehicle body floor 4 by the outer plate 11 and the reinforcing ribs 13 on both sides.

  Further, each side plate 12 of the load transmitting member 10 is a portion that receives an impact load from the side portion of the seat 1 at the time of a side collision, and its protruding height is at least higher than the height of the seat rail 7 of each seat 1. Is set to The protruding height of the side plate 12 is preferably higher than the height of the lower surface of the seat cushion 5, and at least a part of the side plate 12 is opposed to a reclining device (not shown) that tilts the seat back 6 with respect to the seat cushion 5. It is desirable.

  A substantially U-shaped space surrounded by the bottom plate 11 of the load transmitting member 10 and the side plates 12 and 12 on both sides is continuous in the longitudinal direction of the vehicle body, and a passage 14 is opened between the side plates 12 and 12 in the longitudinal direction of the vehicle body.
