Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bracket for a slide rail of a vehicle seat, and more particularly to an improvement of its cover mounting structure.

[0002]

[Prior art]

 FIG. 5 shows an example of a conventional bracket of this type. In the figure, a lower rail 1 on which an upper rail (not shown) is fitted so as to be movable back and forth has a substantially U-shaped cross section that opens upward, and a bracket 2 is fixed to a front end portion thereof. The flat plate portion of the base end of the bracket 2 is fixed to the bottom surface of the lower rail 1 by crimping, and the main body of the bracket 2 is bent and extended in a V shape in a side view along the inclined surface of the front end of the seat leg 4.

The body of the bracket 2 is fixed to the seat leg 4 by inserting a bolt 24 into a mounting hole provided in the plate surface of the tip portion. Both side edges of the bracket 2 main body are bent upward to form standing walls 27, and locking holes 271 are formed at the front ends of these standing walls 27, respectively.

The cover body 3 that covers the bracket 2 is a resin molded product, and has an inverted U-shaped surface that opens downward, and locking projections 371 are provided on the inner surfaces of both side walls 37. Then, after fixing the bracket 2 to the seat leg 4, the cover body 3 is attached to the bracket 2 as shown by the arrow in the figure, and the locking projection 371 thereof is fitted and locked in the locking hole 271.

[0005]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional bracket, the engaging holes 271 for attaching the cover body are provided here by forming the standing walls 27 on both side edges of the main body of the bracket 2, so that the standing wall 27 is not provided unless the cover body 3 is attached. It is prominent and looks bad, and it is necessary to always cover it with the cover body 3. Further, the horizontal width of the bracket 2 is increased by the amount of the standing wall 27, and the cost is increased due to the labor of bending the bracket.

Further, since the cover body 3 is completely separated from the bracket 2, the cover body 3 cannot be continuously attached after fixing the bolts of the bracket 2 and the workability is poor. .

Furthermore, the attached cover body 3 may fall off due to vehicle vibration or the like.

As shown in FIG. 6, it is conceivable to provide a locking piece 28 of a three-way leg for fixing the cover body 3 on the plate surface of the bracket 2 as a separate body. Although the size is small, a man-hour is required instead of manufacturing and assembling the locking piece 28.

The present invention solves such a problem, and a cover body can be omitted depending on the vehicle type, and a bracket for a slide rail of a vehicle seat that can easily and securely attach the cover body with a simple structure. The purpose is to provide.

[0010]

[Means for Solving the Problems]

 To explain the configuration of the present invention, a bracket 2 for fixing one end of a slide rail 1 of a vehicle seat to the vehicle floor side is formed into a flat plate shape, and a maximum plate width d1 is formed on both side edges of a base end portion of the bracket 2. A locking portion 21 having a smaller width is formed in a stepped manner, and on the other hand, one side edge of the cover body 3 covering the bracket 2 is slightly shorter than the maximum plate width d1 of the bracket 2 and smaller than its plate thickness. A slightly wide slit hole 31 is provided, and a thin integral hinge portion 32 that extends linearly along the slit hole 31 and extends freely along the slit hole 31 is formed, and the slit hole 31 is inserted into the bracket 2. After being expanded and deformed, it is fitted and locked in the locking portion 21, and in this state, the cover body 33 is rotated around the integral hinge portion 32 to a position where the bracket 2 is covered, The locking portion 36 provided on the over body 33 is obtained by engaging fixed to the vehicle floor side.

[0011]

In the above structure, since the bracket 2 has a flat plate shape without a standing wall as in the conventional case, the lateral width becomes small and the appearance does not deteriorate even when the cover body 3 is not provided.

By simply inserting the slit hole 31 provided in the cover body 3 into the bracket 2 and fitting it into the locking portion 21, the cover body 3 can be easily fixed, and the slit hole 31 can be passed through the slit hole 31. Therefore, there is no risk that the cover body 3 will fall off the bracket 2 due to vibration or the like.

Further, since the cover body 3 can be attached to the bracket 2 prior to fixing the bracket 2 to the vehicle floor side, after fixing the bracket 2, the cover body 3 is continuously attached. It can be locked and fixed and has excellent workability.

【Example】

 1 and 2, a lower rail 1 as a sliding rail is provided on a seat leg 4 erected on the vehicle floor, and the rail 1 is fixed to the seat leg 4 by a bracket 2 fixed to the bottom surface of the front end thereof. Has been done. The lower rail 1 has a substantially U-shaped cross section that opens upward and supports a vehicle seat S (FIG. 2) via an upper rail (not shown) that is fitted in the lower rail 1 and can slide back and forth.

The bracket 2 is formed by bending a long plate into an L shape in a side view, and is arranged along the front upper corner of the seat leg 4, and the horizontal half portion 23 is caulked on the bottom surface of the front end of the lower rail 1. It is fixed by. The horizontal half portion 23 forms a gap 41 (FIG. 2) between the horizontal half portion 23 and the top wall of the seat leg 4 due to the downward protruding portion 231 formed in part.

The vertical half portion 22 of the bracket 2 has a lateral width that gradually decreases from the base end portion that bends to the horizontal half portion 23 toward the distal end that forms a semicircle, and the base end portion has both sides on both sides. Protrusions 25 are formed on the edges, which are slanted more smoothly than the front end direction and protrude laterally to have a maximum plate width d1, and the rear faces of these protrusions 25 are stepped to have a small width d2 and serve as locking surfaces 21. There is.

The vertical half portion 22 is located in close contact with the front wall of the seat leg 4, and is fixed to the front wall by a bolt 24 (FIG. 2) inserted into a mounting hole 221 in the plate surface of the seat leg 4. A rectangular engaging hole 42 is formed in the front wall portion of the seat leg 4 where the tip of the vertical half portion 22 is located.

The cover body 3 that covers the vertical half portion 22 of the bracket 2 is an umbrella-shaped body having a substantially trapezoidal cross section that is rectangular in plan view, and is entirely formed by integral molding of a resin material, and one side edge thereof is The side portion 35 has a constant width and is divided by a thin linear integral hinge 32. A slit hole 31 is formed in the side portion 35 along the integral hinge 32, and the length d3 of the slit hole 31 is slightly smaller than the maximum plate width d1 of the bracket vertical half portion 22. Moreover, it is slightly larger than the distance d2 between the locking surfaces. The width of the slit hole 31 is slightly larger than the plate thickness of the bracket 2.

In the cover body 3, a locking piece 34 having a triangular cross-section at the tip is formed at the center of the side edge opposite to the side edge on which the integral hinge 32 is provided. A cylindrical engaging portion 36 (FIG. 2) having a diameter slightly smaller than the outer diameter of the bolt head 24 is formed on the inner surface of the top wall of the.

In the cover body 3, the slit hole 31 is inserted into the bracket vertical half portion 22 prior to fixing the bracket 2 to the seat leg 4. In this state, when the slit hole 31 is pushed toward the locking surface 21, the slit hole 31 is gradually stretched and deformed in the longitudinal direction, and when the slit 31 exceeds the maximum plate width d1, the slit hole 31 contracts to the locking surface 21. Engage (see dashed line in Figure 1 and Figure 2).

After that, the bracket vertical half portion 22 is fixed by the bolt 24, and then the cover body 33 is rotated about 90 degrees around the integral hinge 32 as shown by an arrow in FIG. The part 22 is covered. At this time, the engaging piece 34 provided on the cover body 33 is engaged with the lower edge of the engaging hole 42 in the front wall of the seat leg 4, and the tubular engaging part 36 is fitted on the head of the bolt 24. Together, the main body 33 is fixed.

Thus, since the bracket 2 has a flat plate shape, the appearance does not deteriorate even without the cover body 3 being provided, and the bracket 2 is also compact.

Further, due to the simple structure of providing the slit hole 31, the cover body 3 can be easily attached only by passing it through the vertical half portion 22 of the bracket 2. Then, even if frequent vehicle vibrations are input by inserting the slit hole 31, there is no problem such as the cover body 3 falling off. In particular, in this embodiment, the slit hole 31 is inserted into the upper gap 41 beyond the bracket vertical half portion 22 that is tightly bolted to the seat leg 4, and therefore there is no possibility that the cover body 3 will fall off. Absent.

Further, since the cover body 3 can be attached to the bracket 2 prior to fixing the bracket 2 to the seat leg 4, the fixing work of the cover body 3 must be performed after the fixing of the bracket 2. And work is smooth.

Instead of the engaging hole 42 provided in the front wall of the seat leg 4 in the above embodiment, an engaging hole 222 may be provided in the bracket vertical half portion 22 as shown in FIG.

Further, as shown in FIG. 4, if the engaging surface 21 of the bracket vertical half portion 22 is formed as a side wall of the recess 26, the protrusion 25 can be prevented from protruding laterally.

The locking piece 34 of the cover body 33 can be omitted if fixing by the tubular locking portion 36 is sufficient, and the structure can be further simplified.
