The connection of the bracket to the floor panel and the connection of the seat to the bracket are realized by inserting bolts into through-holes drilled in each member and tightening them. Fastening of this bolt is performed using tools, such as an electric screwdriver and an air impact wrench.

By the way, if the shape of the seat is different, it may not be possible to approach the tool for attaching the seat to the floor. In other words, even with the same vehicle model, the seat to be installed may differ depending on options, etc. In such cases, it may be difficult to approach with tools.

As a countermeasure, it is conceivable to change the shape of the floor panel to shift the fixing point of the bolt. However, it is not preferable to change the shape of the floor panel in the same vehicle model just because the shape of the seat is changed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat mounting bracket which eliminates the need to change the shape of the floor panel even if the shape of the seat is changed in the same vehicle model.

One aspect of the seat mounting bracket of the present invention includes:
A seat mounting bracket for mounting a seat to a floor panel of a vehicle, comprising:
At least a first fixing surface having a first fixing point for fixing the bracket to the floor panel and a second fixing surface having a second fixing point for fixing the seat to the bracket. ,
the first and second fixing points are offset from each other at least in the vehicle width direction;
The second fixed surface is inclined forward of the vehicle.

According to the present invention, it is possible to realize a seat mounting bracket that does not require the shape of the floor panel to be changed even if the shape of the seat is changed in the same vehicle model.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a usage example of a seat mounting bracket (hereinafter abbreviated as "bracket") 100 of the present embodiment. The bracket 100 is provided for the purposes of (1) sharing a floor with a seat of other specifications, and (2) improving assembly workability.

In the example of this embodiment, the front portion of the seat 20 is fixed to the floor panel via a bracket 100, and the rear portion of the seat 20 is fixed to the floor panel via another fixing portion such as a fixing pin 11 (not described in detail). be done.

Bracket 100 is fixed to floor panel 10 with bolts 31 . In practice, the bolt 31 reaches a cross member (not shown) on the rear side of the floor panel 10 in order to increase the mounting strength. Seat 20 is secured to bracket 100 by bolts 32 . First, the bracket 100 is fixed to the floor panel 10 with the bolt 31 as shown in FIG. 1, and then the seat 20 is fixed to the bracket 100 with the bolt 32 . Incidentally, a frame 21 projecting toward the bracket 100 is formed at the bottom of the seat 20 , and the seat 20 is attached to the bracket 100 by inserting the bolt 32 through the frame 21 .

FIG. 2 is an enlarged perspective view of the bracket 100. FIG.

The bracket 100 has a first fixing surface 101 having a first fixing point P1 for fixing the bracket 100 to the floor panel 10, and a second fixing surface 101 having a second fixing point P2 for fixing the seat 20 to the bracket 100. 102 and . In practice, the first fixing point P1 is the fastening position of the bolt 31, and the second fixing point P2 is the fastening position of the bolt 32. As shown in FIG. Focusing only on the bracket 100, the first fixing point P1 can be said to be an insertion hole (not shown) through which the bolt 31 is inserted, and the second fixing point P2 is an insertion hole through which the bolt 32 is inserted. can be said to be an insertion hole 103 (FIG. 1).

The first fixed point P1 and the second fixed point P2 are offset by a length L1 in the vehicle width direction. Also, the first fixed point P1 and the second fixed point P2 are offset by a length L2 in the longitudinal direction of the vehicle. Here, the length L1 of the offset in the vehicle width direction is longer than the length L2 of the offset in the longitudinal direction.

FIG. 3A is a cross-sectional view of the first fixing surface 101 taken along the front-rear direction of the vehicle at the position P1 of the first fixing point P1. FIG. 3B is a cross-sectional view of the second fixing surface 102 taken along the front-rear direction of the vehicle at the position P2 of the second fixing point P2.

As can be seen from FIGS. 3A and 3B, the inclination angle θ2 of the second fixing surface 102 toward the front of the vehicle is larger than the inclination angle θ1 of the first fixing surface 101 toward the front of the vehicle. .

In the above configuration, if the size or shape of the seat 20 is changed, the size or the like of the bracket 100 may be changed, so there is no need to change the shape of the floor panel 10 .

In order to arrange the first fixing point and the second fixing point on one bracket 100, the first fixing point and the second fixing point need to be offset. , the method of offsetting is devised.

Considering the behavior of the vehicle, there is a high possibility that greater acceleration occurs frequently in the front-rear direction of the vehicle than in the vehicle width direction. The greater the offset between the first fixing point P1 and the second fixing point P2, the greater the moment that acts on it, and the bracket 100 and the floor panel 10 are more likely to break. Considering this, in the present embodiment, the length L1 of the offset in the vehicle width direction is made longer than the length L2 of the offset in the longitudinal direction. Incidentally, the length L2 of the offset in the front-rear direction may be zero. That is, the first and second fixing points P1 and P2 may be offset from each other only in the vehicle width direction.

However, in the present embodiment, by offsetting the second fixing point P2 to the front of the vehicle from the first fixing point P1, the approach of the tool to the second fixing point P2 becomes easier. You can get the effect of

Since the second fixing surface 102 is inclined in the forward direction of the vehicle, the tool can be easily approached. That is, as shown in FIG. 1, after the bracket 100 is fixed to the floor panel 10, the seat 20 is fixed to the bracket 100 with the bolt 32. Therefore, when tightening the bolt 32, an electric screwdriver or an air impact wrench is required. There is a possibility that a tool such as a tool may interfere with the front end of the seat 20 and make it difficult to approach the bolt 32 with the tool. Therefore, the tool can be approached to the bolt 32 without interference between the tip of the sheet 20 and the tool. This facilitates the work of attaching the seat 20 .

In particular, in the present embodiment, the inclination angle θ2 of the second fixing surface 102 in the forward direction of the vehicle is made larger than the inclination angle θ1 of the first fixing surface 101 in the forward direction of the vehicle. Therefore, it is possible to realize the bracket 100 which is excellent in strength and easy to approach with a tool. In other words, in this embodiment, the force from the floor panel 10 and the force from the seat 20 are received by the fixed surfaces 101 and 102 inclined in different directions, so that the force is received by the fixed surfaces inclined in the same direction. Also, the bracket 100 is less likely to be damaged. Also, since the inclination angle .theta.2 is large, the tool can be approached from a leaner direction without interfering with the tip of the sheet 20. As shown in FIG.

Furthermore, the first fixing surface 101 is formed on the concave surface of the bracket 100, and the second fixing surface 102 is formed on the convex surface of the bracket 100, so that the rigidity of the bracket 100 is increased, and the bracket 100 is more susceptible to breakage. becomes difficult.

By the way, it is conceivable to extend the bracket 100 forward of the vehicle so that the tool can be approached while the mounting angle remains the same. It gets worn out and loses strength. In this embodiment, by changing the angle between the first fixing point P1 and the second fixing point P2, the distance between the first fixing point P1 and the second fixing point P2 is shortened, and the strength is ensured. You can say yes.

As described above, according to the present embodiment, the bracket 100 has at least the first fixing surface 101 having the first fixing point P1 for fixing the bracket 100 to the floor panel 10, and the seat 20 attached to the bracket 100. and a second fixing surface 102 having a second fixing point P2 for fixing the first and second fixing points P1 and P2 are offset from each other at least in the vehicle width direction. The fixing surface 102 of is inclined in the forward direction of the vehicle.

Thus, even if the shape of the seat 20 is changed in the same vehicle type, the shape of the floor panel 10 does not have to be changed, the mounting strength can be ensured, and the approach of the tool is easy, and the bracket 100 can be realized.

The above-described embodiments are merely examples of specific implementations of the present invention, and the technical scope of the present invention should not be construed to be limited by these. That is, the present invention can be embodied in various forms without departing from its spirit or essential characteristics.

INDUSTRIAL APPLICABILITY The present invention is suitable as a seat mounting bracket used when mounting a seat to a floor panel of a vehicle.
