Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a slide rail cover structure for a vehicle seat.

[0002]

[Prior Art]

 A conventional slide rail cover structure for a seat will be described below.

In some cases, a rear end portion of a slide rail of a conventional seat is covered with a cover as shown in FIG. 4 in order to prevent occupant's danger and foreign matter from entering. In the figure, a is fixed to the upper rail b by a seat, and this upper rail b is fitted to the lower rail c so as to be movable in the front-rear direction, and the seat a moves in the front-rear direction together with the upper rail b. .. A bracket e is attached to the front and rear ends of the lower rail c by welding or the like, and the lower end surface of the bracket e is fixed to the floor surface d of the vehicle.

As shown in FIG. 5, the cover f is in the shape of a box with one end surface opened, and one end of a plurality of springs g is attached to the upper surface, and the other end of the spring g is the upper rail b or the sheet. It is fixed to the cushion frame of a.

The operation of the slide rail cover structure configured as described above will be described below. As shown in FIG. 6, when the upper rail b is in front of the lower rail c, the cover f is biased by the cover spring g at the rear end of the lower rail c and the inner surface of the cover f is the rear end surface of the lower rail c. Is in contact with.

Next, as shown in FIG. 7, when the upper rail b is slid rearward, the upper rail b enters the cover f and the rear end surface of the upper rail b contacts the inner surface of the cover f. Further, when the upper rail b is slid rearward, the cover f moves rearward together with the upper rail b. Therefore, the cover f is always covered by either the upper rail b or the lower rail c to prevent the occupant from being injured and the foreign matter from entering.

[0007]

[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, the structure of the cover f is complicated because it requires parts such as springs, and it requires man-hours for processing and assembling, and the slide rails are often processed, resulting in high cost. Had a point.

The present invention solves the above conventional problems, and an object of the present invention is to provide a slide rail cover structure that does not require parts such as springs, has a small number of processing steps, and is safe and inexpensive.

[0009]

[Means for Solving the Problems]

 In order to achieve this object, the slide rail cover structure of the present invention has a rear end of a slide rail in which a lower rail fixed to a vehicle body and an upper rail fixed to a lower surface of a seat are relatively movably fitted. A cover for covering the slide rail, an engaging portion is provided at the rear end of the lower rail and a rear end of the upper rail, and an engaging means for engaging the engaging portion of the lower rail is provided on the inner surface of the cover. And an engaging means for engaging with the engaging portion of the upper rail.

[0010]

[Action]

 With this configuration, when the upper rail moves forward, the cover engaging means engages with the lower rail engaging portion so that the cover covers the rear end of the lower rail, and when the upper rail retreats, the cover engaging means engages the upper rail. The cover covers the rear end of the lower rail by engaging with the engaging part of, so that the rear end of the slide rail is always covered, preventing the danger of the occupant and the entry of foreign matter, and Since parts such as springs are not required and the cover and slide rail can be easily processed, the man-hours are small and the cost is low.

【Example】

 Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a slide rail cover structure, 2 is an upper rail, 5 is a lower rail, and 10 is a cover. The upper rail 2 has a box-shaped cross section with an open lower surface, a hole 4 as an engaging portion is formed at a rear end portion of a side wall 3, and a seat is fixed to an upper surface. The upper rail 2 is fitted to the lower rail 5 so as to be movable in the front-rear direction, and the seat is movable in the front-rear direction together with the upper rail 2. Brackets are attached to the front and rear ends of the lower rail 5 by welding or the like, and the lower end surface of the bracket is fixed to the floor surface of the vehicle.

The lower rail 5 has flanges 7 formed on both upper edges of a lower rail main body 6 having a U-shaped cross section, and a notch 8 as an engaging portion is formed at a rear end of the flange 7. ..

The cover 10 is in the shape of a box having two open sides, and the upper surfaces thereof are partially open so that both side walls 11 have a spring function. A protrusion 12 is formed on the inner surface of each side wall 11 as an engaging means for engaging with the hole 4 at the rear end of the upper rail 2 and engages with the hole 4 of the upper rail 2 when the upper rail 2 is retracted. It is in a relational position to meet.

Further, a protrusion 13 is formed on the inner surface of each of the side walls 11 as an engaging means for engaging with the notch 8 at the rear end portion of the lower rail 5, and the notch 8 of the lower rail 5 when the upper rail 2 is advanced. Is in a relative position to engage.

The operation of the slide rail structure 1 configured as described above will be described with reference to FIGS. 2 and 3. FIG. 2 shows the upper rail 2 in the retracted position. At this time, the projection 12 of the cover 10 is engaged with the hole 4 of the upper rail 2, and the rear end surface of the upper rail 2 is in contact with the inner surface of the cover 10. The engagement between the notch 8 of the lower rail 5 and the protrusion 13 of the cover 10 is released.

Next, when the upper rail 2 is moved forward, the cover 10 also moves forward with the hole 4 and the projection 12 engaged with each other, and when the inner surface of the cover 10 reaches the position shown in FIG. 3 where it abuts on the rear end surface of the lower rail 5, When the protrusion 13 of the cover 10 is engaged with the notch 8 of the lower rail 5, the engagement between the hole 4 and the protrusion 12 is released, and only the upper rail 2 further advances to reach a predetermined position.

Therefore, the rear end portion of the slide rail is always covered to prevent the danger of the occupant and the invasion of foreign matter, and the parts such as the spring are not required, and the cover and the slide rail can be easily processed. Therefore, the number of steps is small and the cost is low.

As described above, according to this embodiment, the hole 4 is provided at the rear end portion of the lower rail 5, the notch 8 is provided at the rear end portion of the upper rail 2, and the inner rail of the cover 10 is provided with the notch 8 of the upper rail 2. By providing the protrusion 13 that engages with the notch 8 of the lower rail 5 when moving forward and the protrusion 12 that engages with the hole 4 of the upper rail 2 when retracting the upper rail 2, the rear end of the slide rail is always covered. In addition, it prevents the occupant's danger, prevents foreign matter from entering, and does not require springs and other parts, and the cover 10 and slide rails can be easily processed. The structure can be obtained.

[0020]

[Effect of the device]

 As described above, the present invention covers the slide rail on the rear end portion of the slide rail rail in which the upper rail fixed to the lower surface of the seat is relatively movably fitted to the lower rail fixed to the vehicle body. A cover is provided, and engaging portions are provided at the rear end portions of the lower rail and the upper rail, and the inner surface of the cover has engaging means for engaging with the engaging portion of the lower rail and an engaging portion of the upper rail. By providing the engaging means for engaging, the rear end of the slide rail is always covered, which prevents the danger of the occupant and the invasion of foreign matter, and does not require any parts such as springs. Since the slide rails can be easily processed, it is possible to realize a slide rail cover structure with a small number of processes and a low cost.
