DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg cover for a seat slide which is mounted so as to cover and hide a leg bracket for fixing a seat slide rail for adjusting the position of a seat back and forth to a vehicle body.

[0002]

2. Description of the Related Art FIG. 7 is a side view schematically showing a seat structure in a general automobile, and FIG. 8 is a schematic structural layout of a seat device. 7 and 8, a seat 51 includes a seat cushion 52 and a seat back 53, and is attached to a floor 55 of the vehicle body via a pair of left and right seat slide rails 54.

[0003] Both seat slide rails 54 have lower rails 56 whose front and rear ends are disposed at a predetermined height on a floor 55 via leg brackets 60, and uppers which are slidably fitted to the lower rails 56 in the longitudinal direction thereof. Rail 5
7 Reference numeral 59 denotes a stopper for fixing the leg bracket 60 on the floor 55. Then, the seat cushion 52 (seat 51) fixes the upper rail 57 to the bottom surface via the bracket 58, and the upper rail 57 and the seat 51 are integrally guided by the lower rail 56 and are moved back and forth. The seat slide rail 54 is provided with a lock mechanism (not shown) that releasably locks the position of the upper rail 57 that has been moved back and forth together with the seat 51 at that position.

[0004] In the seat apparatus using the seat slide rail 54 of this type, the appearance is impaired if the fixed portion of the leg bracket 60 is exposed. Therefore, today, there are many cases in which a leg cover is attached to the leg bracket 57 and the rail portion is covered so as not to be exposed. As the leg cover, those having various structures are used, and can be seen in, for example, Japanese Utility Model Laid-Open No. 5-62323 and Japanese Patent Laid-Open No. 7-266954.

[0005]

However, in the conventional leg cover, not only the appearance treatment at the rear end side of the lower rail 56 is not yet satisfactory, but also, for example, a child or the like on the rear seat side can use the leg cover or the seat slide rail. There is still room for improvement in terms of safety and the like when hitting the rear end of the 54.

The present invention has been made in view of the above background. An object of the present invention is to provide a leg cover for a seat slide that can more reliably improve safety and appearance. Still other objects will be sequentially clarified in the contents described below.

[0007]

In order to achieve the above object, the present invention is, as illustrated in the drawings, attached to the front and rear ends of a lower rail 56 for guiding the movement of an upper rail 57 that moves back and forth together with the seat 51, A leg bracket 60 standing substantially in an L-shape for supporting the lower rail 56 on the floor 55 on the vehicle body side; and a leg cover for seat sliding attached to the leg bracket 60, wherein 56
The leg cover 11 attached to the leg bracket 60 supporting the rear end side of the leg bracket 6
0, which covers the rear end surface of the lower rail 56, and the upper surface side of the curved surface 12 which is substantially continuous from the upper surface 56a of the lower rail 56 to the floor 55 on the vehicle body side. This is the configuration that is being formed. In this structure, more specifically, the upper surface side portion 11A forming the curved surface 12 is formed of a soft resin material, and the lower mounting portion 11B fixed to the leg bracket 60 is formed of a hard resin material. It is preferable that the upper surface side portion 11A has a rail escape portion 14 for allowing the upper rail 57 to escape when the upper surface side portion 11A moves the upper rail 57 to the rear end side.

According to the above-described basic structure of the present invention, the upper surface is moved from the upper surface 56a of the lower rail 56 to the floor 55 of the vehicle body.
When a child or the like hits the leg cover 11, the impact is effectively reduced by the curved surface 12, and at the same time, the arc-shaped curved surface is formed. By doing so, the appearance as the leg cover 11 is also improved.

In the above detailed structure, the lower mounting portion 11B fixed to the leg bracket 60 side is formed of a hard resin material having sufficient strength, and the upper surface side portion 11A exposed in the vehicle interior is formed. Since it is formed of a soft resin material capable of relaxing the impact, the upper surface side portion 11
The shock absorbing capacity of A can be improved without lowering the mounting strength, and the presence of the rail escape portion 14 allows the size and shape of the leg cover 11 to be freely adjusted without being restricted by the movement of the upper rail 57. It has the effect that it can be designed.

[0010]

Further, in this embodiment, the seat slide rails shown in FIGS. 7 and 8 use an example in which the seat slide rails having the same structure are used, and the leg bracket structures shown in FIGS. 1 to 6 are partially used. The structure is basically the same as that of the leg bracket shown in FIGS. 7 and 8 except for the modification. Therefore, FIGS.
7, members corresponding to those in FIGS. 7 and 8 are denoted by the same reference numerals as in FIGS. 7 and 8, and only different parts will be described.

1 to 6, reference numeral 11 denotes a leg cover. The leg cover 11 is a resin molded product, and is formed to have a size that fills a substantially L-shaped outer side of the leg bracket 60 at a portion indicated by reference numeral 10 in FIG. In other words, the leg cover 11 covers substantially the entire rear end surface of the seat slide rail 54 and is in contact with the leg cover 11, and the leg bracket 60 projecting rearward from the rear end surface of the seat slide rail 54 from the outside. It is attached to the leg bracket 60 so as to cover and hide it.

The details of the leg cover 11 will be described below. First, the upper surface side is formed as a curved surface 12 in a state of descending to the floor 55 while continuously drawing an arc from the upper surface 56a of the lower rail 56, It looks almost fan-shaped when viewed from the side. The thickness (left and right widths) is formed to have substantially the same dimensions as the left and right widths of the lower rail 56.
In addition, the corner portion 13 is chamfered so as to have a roundness as a whole, so that the impact when the corner portion 13 is hit is easily reduced. Furthermore, lower rail 5
The portion corresponding to the rear end face 6 has a tunnel portion 14a penetrating back and forth, and a slit 14b continuously penetrating from the tunnel portion 14a to the curved surface 12 on the upper surface side. A rail escape portion 14 is formed. When the upper rail 57 is moved to the rear end side and protruded further rearward from the rear end of the lower rail 56, the rail escape portion 14 is provided with the upper rail 57 and the bracket 58.
Is prevented from hitting the leg cover 11, and the leg cover 11 does not restrict the movement of the upper rail 57 and the bracket 58.

Next, a structure for attaching the leg cover 11 to the leg bracket 60 will be described. The inside of the leg cover 11 below the tunnel portion 14a is shown in FIG.
As shown in FIG. 6, a hollow 15 is formed by hollowing out the lower surface, and the leg bracket 60 can be stored in the hollow 15. Further, the front side (the side facing the seat slide rail 54) is provided in the hollow portion 15.
In addition, a front locking piece 16 having a locking claw 16a at the tip is provided integrally with the leg cover 11, and a pair of lower locking claws 17 are respectively formed on the left and right inner walls 15a and 15b on the bottom surface side. Are protruded inward and are provided integrally. In addition, on the leg bracket 60 side, an engagement hole 61 is provided corresponding to the front locking piece 16, and a cutout portion 62 formed by cutting out a part of the leg bracket 60 is formed on the lower locking claw 17. Is provided correspondingly.

When the leg cover 11 is attached to the leg bracket 60, the front surface of the leg bracket 60 is made to extend along the rear end surface of the lower rail 56.
The leg cover 11 is lowered from above the leg bracket 60. When it is lowered to an intermediate position, the locking claw 16 a of the front locking piece 16 is inserted into the engagement hole 61, and the lower locking claw 17 corresponds to the notch 62. When it is further lowered to the final position, the locking claw 16a of the front locking piece 16 is hooked on the edge of the engagement hole 61 as shown in FIG. But notch 6
The leg cover 11 is attached to the leg bracket 60 with a predetermined retaining strength by both the hooks. When the leg cover 11 is attached to the leg bracket 60 in this manner, the rail escape portion 14
Are in a state corresponding to the lower rail 56. Therefore,
When the upper rail 57 is moved rearward and projects further rearward from the rear end of the lower rail 56, the upper rail 57 and the bracket 58 can move through the rail escape portion 14 without colliding with the leg cover 11. When the leg cover 11 is to be removed from the leg bracket 60, the locking of the locking claw 16a and the lower locking claw 17 is removed, and then the leg cover 11 is pulled upward.

Next, the manufacture of the leg cover 11 will be described. The leg cover 11 is formed by a two-color molding method on an upper surface side portion (a portion shown in a satin pattern in FIGS. 1, 2, and 6).
11A is formed of a soft resin material, and the lower mounting portion 11B is formed of a hard resin material. Here, the front locking piece 16 and the lower locking claw 17 are located at the lower mounting portion 11B and are formed of a hard resin material. This is to ensure sufficient mounting strength of the leg cover 11 to the leg bracket 60. The soft resin material is, for example, a foamed resin material, and has such a softness that the occupant can buffer when hit by an occupant. On the contrary,
The hard resin material is a material that is one step harder than the soft resin material. Such a leg cover 11 may be formed integrally with rubber, for example.

The leg cover 11 having the above structure is improved in the following points as compared with the conventional product. First, the curved surface 12 on the upper surface side is formed as a continuous curved surface by drawing an arc from the upper surface 56a of the lower rail 56 of the seat slide rail 54 to the floor 55 of the vehicle body, and the corner portion 13 is rounded. Further, since the upper surface side portion 11A exposed in the vehicle cabin is formed of a soft resin material, when an occupant or the like hits the leg cover 11, the impact can be efficiently mitigated. High security is obtained. Second, at the same time, the curved surface 12 on the upper surface side is
The appearance as a cover is improved by forming a continuous curved surface by drawing an arc from a to the floor 55 of the vehicle body. Third, since the lower mounting portion 14B provided with the front locking piece 16 and the lower locking claw 17 is formed of a hard resin material which is sufficiently satisfied, the mounting strength is high without lowering the mounting strength. Safety is obtained. Fourth, the upper rail 57
Is moved to the rear end side, the upper rail 57
Since the rail escape portion 14 for releasing the rail is provided corresponding to the lower rail 16, the size and shape of the leg cover 11 can be freely designed without being restricted by the movement of the upper rail 27.

The structure for attaching the leg cover 11 to the leg bracket 60 is not limited to the structure of the above embodiment, but may be changed as needed. Alternatively, it may be fixed by screwing or pasting.

[0019]

As described above, in the seat leg cover of the present invention, the outside of the leg bracket, which is substantially L-shaped, is buried to cover the rear end surface of the lower rail, and
Since the upper surface side is formed as a curved surface that is substantially continuous from the upper surface of the lower rail to the floor on the vehicle body side, when a child etc. on the rear seat side hits the leg cover, the impact is caused by the curved surface. The relief is effectively alleviated, and at the same time, the appearance as a leg cover is improved by eliminating the steps and forming a curved surface. That is, the present invention is
In particular, when the seat is installed at a position higher than the floor by the leg bracket, the appearance such as safety and appearance when hitting the leg cover can be more reliably obtained with a simple configuration.
