DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 to 3 show a cab-over type vehicle body mounting structure in which a vehicle compartment is provided above a non-monocoque body, and 1 is a front seat.
The seat cushion 2 and the seat back 3 are connected via hinge means (not shown), and the seat back 3
The headrest 4 is attached to the upper side of the headrest. The seat 1 is a so-called seat belt-in-seat in which a buckle 5a (see FIG. 5) as an engaging portion of the seat belt 5 is connected to the seat frame 1a.

The frame of the seat cushion 2 is connected to front and rear seat brackets 7A, 7B, 7C, 7D via slide mechanisms 6A, 6B, and is located outside of the seat brackets 7A to 7D. The front and rear seat brackets 7B, 7D are located below the seat brackets 7B, 7D via a floor panel 8 as a cabin floor constituting a part of the cabin. The cab mount bracket 9 is attached to the cab mount bracket 9. Seat seat 1
The slide mechanism 6A, 6B allows the vehicle to slide in the vehicle longitudinal direction to adjust the longitudinal position.

As shown in FIG. 4, the cab mount bracket 9 includes an inner panel 14a and an outer panel 1.
4b is joined together with the floor panel 8 to the inner panel 14a of the closed section member 14 joined to the inner panel 14a.
The rear seat bracket 7D is also joined to a pillar 15 formed by joining a pillar inner 15a and a pillar outer 15b extending upward from the inner panel 14a and the outer panel 14b.

The cab mount bracket 9 is provided so as to straddle between the front and rear seat brackets 7B and 7D, and each of the seat brackets 7B and 7D is mounted with the floor panel 8 interposed therebetween. It is spot-welded to the mount bracket 9. As a result, the sheet brackets 7B and 7D are connected via the floor panel 8 and the cab mount bracket 9 to ensure strength. The inner seat brackets 7A, 7C
Is disposed in the vicinity of a so-called tunnel portion 8a projecting upward from the floor panel 8, and the tunnel portion 8a
The strength is secured by.

A reinforcement 10 is interposed between the rear seat brackets 7C and 7D so as to reinforce their mounting portions. Reference numerals 11 and 12 denote other cab mount brackets located before and after the cab mount bracket 9, respectively, and reference numeral 13 denotes another seat located behind the seat 1.

As shown in FIGS. 5 to 7, the seat belt 5 has a pillar portion 1 at one end through a shoulder anchor 21.
5 and is housed in a retractor 22 provided below the pillar portion 15, and the other end portion of the cab mount bracket 9 is
And an engaging member 5b is provided at an intermediate portion so as to be removably engaged with the buckle 5a. The mounting portion of the shoulder anchor 21 is reinforced by a reinforcement 24. The pillar portion 15 is covered with a pillar trim (not shown).

With the above structure, even if a large load acts on the seat 1 through the seat belt 5 in the event of a collision, the load is applied to the high-strength cab mount bracket 9 through the sheet brackets 7B and 7D. Since the power is transmitted and received, the load acting on the seat belt anchor portion is reduced, so that the load acting through the seat belt 5 causes the front seat bracket 7B to fall downward and the rear seat bracket 7D to rise upward. Is suppressed. Also, the seat bracket 7
A, 7C is secured by the tunnel portion 8a located near it, and similarly to the seat brackets 7B, 7D, the front seat bracket 7A is lowered,
The rear seat bracket 7C does not move upward.

Therefore, the support of the seat 1 is strengthened, and the support of the seat 1 is ensured even in a case where a large load acts on the seat 1 at the time of collision, such as 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.
A cab mount bracket is disposed at least below the front seat bracket of the vehicle, and at least the front seat bracket is connected to the cab mount bracket via a floor panel.
Of the front part of the
In that case, the front and rear seat brackets may be respectively connected to separate cab mount brackets located therebelow.

Further, when a cab mount bracket is provided for each of the front and rear seat brackets, the cab mount bracket corresponding to the rear seat bracket may be formed larger than the cab mount bracket corresponding to the front seat bracket. Even if the front seat bracket is configured to be disengaged from the shock absorbing property at the time of collision, the cab mount bracket corresponding to the rear seat bracket is formed large and is difficult to be disengaged, so the seat 1 does not move. Therefore, the position of the occupant is maintained, and the occupant can be hardly affected by the detachment of the front seat bracket.

[0024]

As described above, according to the first aspect of the present invention, the cab mount bracket is fixed to the lower surface of the cabin floor constituting the cabin, and at least the front seat of the seat with respect to the cab mount bracket. Since the brackets are connected across the cabin floor, even if a load is applied to the seat and the front seat bracket such that the seat is dropped from the engagement portion of the seat belt to the front lower side in the event of a collision, the input is also performed. The load can be reliably received by the vehicle body frame via the passenger compartment floor and the cab mount bracket, and the occurrence of the seat drop can be reliably avoided. Further, the load acting on the seat belt anchor portion is reduced.

According to the second aspect of the present invention, since the cab mount bracket is disposed so as to straddle between the front and rear seat brackets, not only the front seat bracket drops but also the rear side. 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 hard to come off.
