【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3 showing the body mount structure of a cab-over type automobile in which a vehicle compartment is provided on the upper side of a non-monocoque body, 1 is a front seat, which is a seat cushion 2 and a seat back 3. Are connected via a hinge means (not shown), and a headrest 4 is attached to the upper side of the seat back 3. The seat 1 is a so-called seat belt-in-seat in which a buckle 5a of a seat belt 5 is connected to a seat frame 1a.

The frame of the seat cushion 2 is coupled to the front and rear seat brackets 7A, 7B, 7C and 7D via slide mechanisms 6A and 6B, and is located outside of the seat brackets 7A to 7D. Seat brackets 7B and 7D are connected via a floor panel 8 to a cab mount bracket 9 that is located below the seat brackets 7B and 7D and that is used to mount the passenger compartment to the vehicle body. The seat sheet 1 can be slid in the front-rear direction of the vehicle body by slide mechanisms 6A and 6B to adjust the front-rear position.

Further, as shown in FIG. 4, the cab mount bracket 9 is joined together with the floor panel 8 to the inner panel 14 a of the closed cross-section member 14 formed by joining the inner panel 14 a and the outer panel 14 b. .. The rear seat bracket 7D is also joined to the pillar 15 formed by joining the pillar inner 15a extending upward from the inner panel 14a and the outer panel 14b and the pillar outer 15b.

The cab mount bracket 9 is arranged so as to straddle between the front and rear seat brackets 7 B and 7 D, and the seat brackets 7 B and 7 D are spot welded to the gab mount bracket 9. .. As a result, the sheet brackets 7B and 7D are connected to each other via the floor panel 8 and the cab mount bracket 9 to ensure strength. The inner seat brackets 7A and 7C are arranged near the so-called tunnel portion 8a protruding upward on the floor panel 8, and the tunnel portion 8a ensures the strength.

A reinforcement 10 is provided between the seat brackets 7C and 7D so as to reinforce the mounting portions thereof. Reference numerals 11 and 12 are separate cab mount brackets located in front of and behind the cab mount bracket 9, and 13 is another seat seat located on the rear side of the seat seat 1.

As shown in FIGS. 5 to 7, the seat belt 5 has one end inserted through the shoulder anchor 21 into the pillar portion 15 and is housed in a retractor 22 provided below the pillar portion 15. The other end is connected to the cable mount bracket 9 by the wrap anchor 23, and the middle part is provided with an engaging tool 5b that is removably engaged with the buckle 5a. The shoulder anchor attachment portion is reinforced by a rain reinforcement 24. The pillar portion 15 is covered with a pillar trim (not shown).

With the above configuration, even if a large load acts on the seat 1 through the seat belt 5 at the time of a collision, the load is high through the seat brackets 7B and 7D. The load acting on the seat belt anchor is reduced, and the load applied through the seat belt 5 causes the front seat bracket 7B to fall downward and the rear seat bracket 7D to float upward. Is suppressed. Further, the seat brackets 7A, 7C have strength secured by the tunnel portion 8a located in the vicinity thereof, and like the seat brackets 7B, 7D, the front seat bracket 7A is lowered or the rear seat bracket is broken. 7C never goes up.

Therefore, the seat seat 1 is strongly supported, and the seat seat 1 is reliably supported even when a large load acts on the seat seat 1 at the time of a collision like a belt-in-seat. ..

In the above embodiment, the front and rear seat brackets 7B and 7D are connected to one cab mount bracket 9 which is long in the front-rear direction, but the cab mount is at least below the front seat bracket of the seat seat. By disposing the bracket and connecting at least the front seat bracket to the cab mount bracket via the floor panel, it is possible to avoid the problem of the front portion of the seat 1 that falls, and In that case, the front and rear seat brackets may be connected to separate cab mount brackets located below them.

Further, when the cab mount bracket is provided for each of the front and rear seat brackets, the cab mount bracket corresponding to the rear seat bracket is larger than the cab mount bracket corresponding to the front seat bracket. If it is formed, even if the front seat bracket is configured to come off due to the shock absorption at the time of a collision, the cab mount bracket corresponding to the rear seat bracket is made large so that it is difficult to come off. The passenger does not move, the occupant's position is maintained, and the occupant is hardly affected by the front seat bracket being disengaged.

[0024]

[Effect of the device]

 According to the invention of claim 1, as described above, since the cab mount bracket for supporting the vehicle compartment is disposed at least below the front seat bracket of the seat sheet, the load input through the seat bracket is applied to the cab. It is received by the mounting bracket, and the front seat bracket does not fall. Further, the load acting on the seat belt anchor portion is reduced.

According to the second aspect of the present invention, the cab mount bracket is disposed so as to straddle between the front seat bracket and the rear seat bracket. Therefore, not only the front seat bracket is dropped, but also the rear seat bracket is dropped. Lifting of the seat bracket is also prevented.

According to the third aspect of the present invention, the cab mount bracket corresponding to the rear seat bracket is formed larger than the cab mount bracket corresponding to the front seat bracket. Even if the seat bracket comes off, the cab mount bracket corresponding to the rear seat bracket is large and hard to come off, so the occupant is hardly affected by the removal of the front seat bracket.
