Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a seat slide mounting structure, and more particularly to an optimum seat slide mounting structure for an automobile when the seat slide is fixed to a floor with bolts.

[Conventional technology]

Conventionally, a seat slide for an automobile is fixed to a floor by tightening a bolt on a floor surface via a bracket fixed to a lower rail of the seat slide (see, for example, JP-A-62-238136).

[Problems to be solved by the device]

However, in this case, particularly when the seat position is set to the forefront, the metal seat slide is exposed, so that there is a feeling of protrusion and it does not look good and is dangerous.

Further, the number of parts is increased, which is disadvantageous in terms of weight and cost.

Such a problem is particularly noticeable when a lower rail having a substantially rectangular cross-section having a strip portion on the upper surface is bolted to the floor of the vehicle body. That is, since it may be impossible to connect the bolts through the narrow portion of the lower rail, a bracket or the like that is bolted to the floor of the vehicle body must be fixed to the end of the lower rail.

An object of the present invention is to solve the above-mentioned conventional problems, to eliminate the feeling of protrusion and improve the appearance, and also to provide the mounting structure of the automobile seat slide which can reduce the number of constituent parts and contribute to weight reduction and cost reduction. To do.

[Means for Solving the Problems]

In order to achieve the above object, the mounting structure of a vehicle seat slide according to the present invention is configured such that an upper rail and a lower rail having a substantially square cross section having a strip portion on the upper surface are slidably fitted. In a mounting structure for mounting a seat slide for an automobile on a floor of a vehicle body, the base portion inside the lower rail is located below the strip at the end of the lower rail in the longitudinal direction, and extends outward from the end of the lower rail. Is inclined and a hole is formed in the inclined surface, and the floor of the vehicle body is also formed with a hole in which the inclined surface is formed, and the inclined surfaces are joined and bolted together.

[Action]

According to the present invention, the lower rail is bolted after the slope portion formed in the base portion thereof and having the hole formed therein is joined to the slope portion formed in the floor and having the hole formed therein.

Therefore, since the base portion of the lower rail directly contacts the floor, the feeling of protrusion is eliminated and the appearance is improved. Further, since the bracket is unnecessary, the weight can be reduced and the cost can be reduced. Moreover, since the fastening surface is an inclined surface, the bolt fastening work can be easily performed.

〔Example〕

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

1 to 4 show an embodiment of the present invention.

In the figure, reference numeral 1 denotes a seat, which is configured by attaching a cushion member to a frame member as is well known, and has an anchor portion 1A to which one end of a seat belt is fixed on the left rear side thereof. The frame member of the seat 1 is fixed to the upper rail 3 with bolts, nuts and the like.

In this embodiment, the upper rail 3 is formed by combining two L-shaped members having a vertical bent portion 3A at the tip end thereof, and the combined portion forms the vertical wall 3B and the remaining lower wall 3C. Form. The vertical wall 3B is provided with a plurality of mounting holes 3D for fixing the above-described seat 1.

Next, the lower rail 5 with which the upper rail 3 is slidably engaged is formed in a substantially square cross-section having a strip portion in the center of the upper surface. More specifically, the base portion 5A, the vertical wall portion 5B, the upper surface horizontal portion. 5C and a vertical bending portion 5D in which the tip of the upper surface horizontal portion 5C is bent and formed. Further, sloped portions 5E are formed at both ends of the base portion 5A by press molding or the like, and the sloped portions 5E are provided with mounting holes 5F for mounting on a floor, which will be described later. Then, the inclination of the inclined surface portion 5E is set so that the center line of the mounting hole 5F deviates from both end edges of the upper surface horizontal portion 5C.

Further, 7 is a floor of the vehicle body, and 7A is a concave groove formed on this floor. On the bottom surface of the concave groove 7A, a slope portion 7B is also formed with the same inclination and a mounting hole 7C is formed at a position corresponding to the slope portion 5E and the mounting hole 5F of the lower rail described above. A nut 7D is welded to the back surface of the sloped portion 7B. Both ends of the groove 7A in the longitudinal direction are the above-mentioned mounting holes.
The inclined portion 7E has the same inclination as the inclination of the center line of 7C.

Further, 9 is a cover plate, and a slit 9A is formed in the center thereof. Further, vertical bending portions 9B are formed at both ends of the slit 9A in the front-rear direction, that is, at positions outside the length of the lower rail 5, and mounting ears 9C are provided on both front and rear sides of the cover plate 9. It is provided.

Then, first, the upper rail 3 and the lower rail 5,
A roller member (not shown) is provided between the lower surface wall 3C of the upper rail 3 and the bottom surface 5A of the lower rail 5 so as to be slidably engaged, the lower surface wall 3C of the upper rail 3 and the vertical bending portion 3A, and the lower rail 5. A ball member (not shown) is inserted in a space formed by the upper surface horizontal portion 5C and the vertical bending portion 5D to be sub-assembled.

Then, this sub-assembled slide rail is installed in the concave groove 7A of the floor 7 by joining the slopes 5E and 7B to each other, and the bolt 10 is inserted from the mounting hole 5F to the mounting hole 7C and fastened to the nut 7D. Set up. When tightening the bolt 10, the center lines of the mounting holes 5F and 7C are the inclined portion 7E of the concave groove 7A.
Since the slopes 5E and 7B are inclined so as not to interfere with both end lines of the upper surface horizontal portion 5C of the lower rail 5, the fastening work can be easily performed with an ordinary wrench or the like.

After that, the cover plate 9 covers the recessed groove 7A, and the mounting ears 9C are welded to be fixed to the floor 7.

In this state, the cover plate 9 contacts the upper surface horizontal portion 5C of the lower rail 5, and the lower end of the vertical bending portion 9B faces the lower surface wall 3C of the upper rail 3.

Therefore, the cover plate 9 hides the concave groove 7A, prevents foreign matter from entering, and improves the appearance.

In addition, even if a force to separate the upper rail 3 from the lower rail 5 is input from the anchor portion 1A due to a vehicle collision or the like, in the present embodiment, the cover plate 9 causes the upper rail 3 and the lower rail 5 to engage with each other. Since I am holding the top surface,
It acts as a strength member for preventing the deformation of both rails, and the peel strength is improved.

Further, even when the above-described peeling direction input is made in a state where the upper rail 3 is slid backward, the lower surface wall 3C of the upper rail 3 contacts the lower end of the vertically bent portion 9B of the cover plate 9, Peel strength is secured.

In the present embodiment, the mounting ears 9C are provided to fix the cover plate 9 to the floor, and the parts are welded.
The entire circumference of the groove may be welded, which can further increase the strength.

According to the present embodiment, since the slide rail is arranged in the groove of the floor and further covered with the cover plate, foreign matter is prevented from entering and the appearance is good, and the peel strength can be improved.

Further, as a result, the plate thickness of the rail member can be reduced.

[Effect of device]

As is apparent from the above description, according to the present invention, since the lower rail and the floor are each formed with a slope portion and both are directly joined to each other by bolt connection, it is possible to improve the appearance without a projection feeling. It is possible to reduce the weight and the cost.

That is, since the slope portion of the lower rail is formed directly on the base portion of the lower rail, compared to the conventional case where the slope portion is formed by a bracket that is separate from the lower rail,
Weight reduction and cost reduction can be realized. Further, since the slope portion of the lower rail is formed on the inner base portion of the lower rail, that is, the base portion of the lower rail itself that does not project from the end portion of the lower rail, the bolt connecting portion between the slope portion and the slope of the vehicle body floor is external. Without revealing
You can improve the appearance by eliminating the protrusion. In addition, since the slope of the lower rail is inclined toward the outside of the end of the lower rail, the slope is formed on the inner base of the lower rail, but it is obstructed by the upper surface of the lower rail. Instead, it can be easily bolted from the outside of the end of the lower rail.

In particular, there is a problem in the case of bolting a lower rail having a square cross section having an upper surface with a cross section to the floor of the vehicle body, that is, bolting through the narrow portion of the lower rail may be impossible, and It is possible to eliminate the problem that a bracket or the like that is bolted to the floor must be provided at the end of the lower rail.
