Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding seat, and particularly to a rail mounting structure for a sliding seat suitable for use in automobiles.

Generally, a sliding seat provided in an automobile is installed on the vehicle body floor by a pair of slide rails so that the seat can be moved in the longitudinal direction of the vehicle.

In the conventional sliding seat, as shown in Figs. 1 to 3, slide rails 1, 1 are attached to the lower part of the seat cushion 2a provided in the front seat of the vehicle body A. In (front most), the upper rail 1a of the slide rail 1 moves forward, and the amount of rearward protrusion of the lower rail 1b becomes maximum, thereby exposing the lower rail 1b.

Therefore, due to the exposure of this lower rail 1b,
This has the drawback that it spoils the appearance, and there are other problems such as the risk of damaging the legs of rear seat passengers and the possibility of staining with grease.

Further, this lower rail 1b is attached to the vehicle body floor 4 on the side sill inner panel 5 side by a mounting bracket (seat bracket) 3', and is further attached on the back bone 6 side by a mounting bracket 3. The mounting brackets 3, 3', and 3'' also cause the problem that the foot space is narrowed, as shown by the symbols h and w in FIG. 2, respectively.The symbol 12 in FIGS. It shows.

Also, the rear most position of seat 2
In this case, the upper rail 1a of the slide rail 1 moves rearward, and the amount of forward protrusion of the front part of the lower rail 1b becomes maximum, causing an appearance problem similar to that of the front most.

This invention aims to solve these problems, and in addition to expanding the foot space and improving the appearance, the present invention is a slide-type seat rail mounting structure that increases the rigidity of the side inner panel that serves as the lower rail mounting part. The purpose is to provide

For this reason, the rail structure of the sliding seat of the present invention is suitable for a sliding seat located adjacent to the side of a side sill inner panel in a car that forms a closed space together with a side sill outer panel. It has an upper rail and a lower rail that slidably supports the upper rail and is attached to the side sill inner panel. The present invention is characterized in that the lower rail mounting portion is integrally provided, and a support bracket formed to match the shape of the lower rail mounting portion is provided along the back surface of the lower rail mounting portion.

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Figures 4 and 5 show a rail mounting structure for a sliding seat as an embodiment of the present invention, and Figure 4 corresponds to Figure 2. The elevational view shown in FIG. 5 is a perspective view of the main parts thereof.

As shown in FIGS. 4 and 5, a lower rail mounting portion 7 is formed on the outer surface of the side sill inner panel 5 constituting the body panel, and is projected toward the inside of the vehicle. A horizontal portion 7a is recessed from the top of the side sill inner panel 5 adjacent to the lower rail attachment portion 7.

In the closed space surrounded by the side sill inner panel 5 and the side sill outer panel 12, a support bracket 13 is attached to the back surface of the lower rail attachment portion 7.
In order to sandwich this reinforcement bracket 13,
A mounting bracket 9 for the lower rail 1b is fastened to the lower rail mounting portion 7 with bolts 10.

Then, attach upper rail 1 to lower rail 1b.
An adjuster bracket 8, which is fixed to the upper rail 1a, is attached to the seat cushion 2a with bolts or the like.

A rail 1 consisting of such an upper rail 1a and a lower rail 1b is a seat cushion 2.
A pair are attached to the lower side of a.

In addition, the center side of the vehicle body of the seat cushion 2a is
The vehicle body A is connected via the bracket 11, upper rail 1a, lower rail 1b and bracket 14.
It is attached to the back bone 6 of the.

In this manner, each of the brackets 9 and 14 is attached to the lower rail attachment portion 7 and the back bone 6, which are both spaced upward from the vehicle body floor 4.

With the above-described configuration, the upper rail 1a and the lower rail 1b can be arranged at a sufficient distance from the vehicle body floor 4 (see symbol H in FIG. 4),
The overhang of the upper rail 1a and lower rail 1b is not visible from the rear seat or the front seat, and the appearance is improved.

In addition, in terms of functionality, the distance between the pair of left and right slide rails 1, 1 is increased (see symbol W in Fig. 4), and the mounting positions of the brackets 9, 14 are raised, so that the brackets 9, 14 themselves The height is sufficiently low to further improve stability.

Further, a lower rail mounting portion 7 having a horizontal portion 7a formed by protruding the side sill inner panel toward the inside of the vehicle.
are integrally formed, so the cross-sectional area of the closed space formed by the side sill inner panel 5 and the side sill outer panel 12 is not reduced, and the lower rail can be attached with a structure that prevents a decrease in the bending rigidity of the side sill. can be done.

Further, since the reinforcement bracket 13 is provided along the back surface of the lower rail mounting portion 7, the rigidity of the lower rail mounting portion 7 can be increased.

As described in detail above, according to the rail mounting structure for a sliding seat of the present invention, the following effects and advantages can be obtained.

(1) When a sliding seat is installed in a car, even if the front seat is set to front most or rear most, the overhang of the upper rail or lower rail will be reflected in the field of view of the occupant in the rear or front seat. There isn't. This makes it possible to improve the appearance.

(2) The seat bracket can be eliminated and the foot space is expanded, thereby greatly improving the comfort of the rear seats.

(3) The load is properly transmitted to the vehicle body, making the sliding seat more stable.

(4) Since the side sill inner panel is pushed out to the inside of the vehicle and the lower rail attachment part is integrally provided, there is no reduction in the cross-sectional area of the closed space formed by the side sill inner panel and side sill outer panel. Therefore, the lower rail can be installed with a structure that prevents a decrease in the bending rigidity of the side sill inner panel.

(5) Since the lower rail attachment part is integrally provided with the side sill inner panel, the number of parts is small and it is advantageous in terms of cost.

(6) A support bracket is provided along the back side of the lower rail attachment part, so when the lower rail is supported on the side sill, it prevents the lower rail attachment part of the side sill from deforming due to the load of the seat or passenger. It can be prevented.
