Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention comprises a floor-side rail that is fixed to the floor side of a vehicle body and the like, and a seat-side rail that is slidably fitted in or out of the floor-side rail along its lengthwise direction to mount a seat. Regarding the rail cover attached to the end of the rail unit.

[0002]

[Prior art]

 As a conventional rail cover of this type, for example, there is one as shown in Japanese Utility Model Laid-Open No. 58-140834.

That is, in a rail unit in which an upper rail (seat side rail) is slidably mounted on a lower rail (floor side rail), an end of the rail unit is placed between the upper rail and the lower rail in the maximum sliding position. It is covered with a coverable rail cover, and the safety cover is always in spring contact with the end of the lower rail by a spring.

[0004]

[Problems to be solved by the device]

 However, in such a conventional rail cover, since the entire moving distance of the rail cover due to the sliding of the upper rail is large, a dedicated spring for keeping the rail cover always following the upper rail, or a spring for the rail and the cover, respectively. There is a problem that the number of parts is increased, the number of assembling steps is increased, and the cost is increased because a bracket or the like is required for locking.

In addition, the total length of the rail cover needs to be equal to or more than the length between the upper rail and the lower rail in the maximum slide position, which increases the size of the entire rail cover, which is contrary to the request for space saving. However, there is a problem that interference easily occurs between the rail cover and other members on the floor side.

The present invention has been made by paying attention to such a conventional problem, and conceals the end portions of both rails with a simple configuration without impairing the operability of the rail unit, thereby ensuring safety. The purpose of the present invention is to provide a rail cover that can improve the appearance and appearance, and further realize a request for space saving by downsizing the cover itself and prevent interference with other members. I am trying.

[0007]

[Means for Solving the Problems]

 The gist of achieving the above object is to provide a floor side rail (30) fixed to the floor side of a vehicle body and the like, and to be slidable along the longitudinal direction with respect to the floor side rail (30). A rail cover (40) attached to an end of a rail unit (10) that is internally or externally fitted and includes a seat side rail (20) for mounting a seat, comprising: the floor side rail (30) and the seat side rail (30). Of the rails (30) on the outer fitting side of 20), there is an opening (42) which is mounted so as to cover the outer wall of the rail (30) on the outer fitting side and through which the end of the rail (20) on the inner fitting side can be relatively inserted. The formed cover body (41) and the cover body (41) are separate bodies, and the cover body (41) is detachably attached to the opening periphery (42a) so as to open and close the opening (42). A body (44) and As the rail unit (10) slides, when the end of the rail (20) on the inner fitting side comes out from the opening (42) of the cover body (41) to the outside, the lid (44) closes the opening peripheral edge. The lid (44) is detachable from (42a) and is attached to the end of the rail (20) on the inner fitting side. The terminal edge of the end of the rail (20) on the inner fitting side is detachably held by the lid (44). When the end (46) of the rail (20) on the inner fitting side is inserted into the inside of the opening (42) of the cover body (41), the lid (44) is positioned on the inner fitting side. The engaged part (50) provided on the inner wall of the end of the rail (30) on the outer fitting side should be separated from the end of the rail (20) and close the opening (42). The rail cover (40) is characterized in that a disengageable engaging part (47) is provided on the rail cover (40).

[0008]

[Action]

 Of the floor-side rail (30) and the seat-side rail (20), the ends of the rails (30) on the outer fitting side are hidden by the cover body (41) mounted so as to cover the outer wall thereof. This eliminates the risk of burrs and sharp edges at the terminal openings of the rails (30) on the outer fitting side, which improves the safety of the rail unit (10) and improves its appearance.

In a state where the end portion of the inner fitting side rail (20) completely fits inside the outer fitting side rail (30), the opening (42) of the cover body (41) has the opening. It is closed by a lid (44) attached to the peripheral edge (42a). At this time, the engaging portion (47) provided on the lid (44) is engaged with the engaged portion (50) provided inside the end of the rail (30) on the outer fitting side, and thus the opening The lid (44) does not easily come off from the peripheral edge (42a), and the terminal of the rail unit (10) cannot be seen through the opening (42) of the cover body (41), which makes it look good. Improves the appearance quality.

As the rail unit (10) slides, when the end of the rail (20) on the inner fitting side relatively comes out from the opening (42) of the cover body (41) to the outside, the opening (42) is opened. The lid (44) that closes the rail is pressed outward by the end of the rail (20) on the inner fitting side, and the engaging portion (47) of the lid (44) is pressed by the pressing force to the rail (30) on the outer fitting side. ) While being disengaged from the engaged portion (50) at the end portion, the sandwiching portion (46) provided on the lid body (44) is engaged with the terminal edge of the end portion of the rail (20) on the inner fitting side this time.

As a result, the lid body (44) is attached to the end portion of the rail (20) on the inner fitting side that has come out from the opening portion (42) of the cover body, and the lid body (44) is fitted inside. Since it does not easily come off from the end of the rail (20) on the side, any end of any rail (20, 30) that constitutes the rail unit (10) does not interfere with the sliding operation of the rail unit (10). Also, the rail unit (10) is always covered with the rail cover (40), so that the safety and appearance of the rail unit (10) can be maintained.

On the other hand, when the end of the rail (20) on the inner fitting side relatively enters inside the opening (42) of the cover body (41), the lid (44) collides with the peripheral edge (42a) of the opening. However, due to the collision force at that time, the holding portion (46) of the lid (44) is disengaged from the terminal edge of the end of the rail (20) on the fitting side, while the lid (44) is removed. The engaging portion (47) of the above engages with the engaged portion (50) at the end of the rail (30) on the outer fitting side. As a result, the opening (42) of the cover body is closed again by the lid body (44).

As shown in FIGS. 1 and 2, the one lid 44 is made of a synthetic resin plate member corresponding to the shape of the peripheral edge 42 a of the opening 42 of the cover body 41, and the peripheral edge 42 a of the opening 42 is formed. A pair of sandwiching portions 46, 46 located at both upper ends of the lid body 44 that are in contact with the upper and lower edges of the sliding contact portion 21 of the seat side rail 20 are provided. More specifically, the sandwiching portions 46 face each other so as to face each other in the vertical direction, and each of the sandwiching portions 46 has a pair of clips having protrusions that can be fitted into the small holes 21a formed in the upper end edge of the sliding contact portion 21. It consists of pieces 45, 45.

Furthermore, the inner surface of the lid body 44 is engaged with and disengaged from the engaged member 50 which is located below the pair of sandwiching portions 46, 46 and which is provided on the inner wall of the bottom surface portion 31 of the lower rail 30. Possible engagement parts 47 are provided. More specifically, the engaging portion 47 is provided with a fitting protrusion 49 on the lower side of the tongue piece 48 protruding from the inner surface of the lid body 44. On the other hand, the engaged member 50 is formed with a concave groove 51 into which the fitting protrusion 49 of the engaging portion 47 can be fitted.

The mutual relationship between the engagement / disengagement of the pair of sandwiching portions 46 with respect to the sliding contact portion 21 and the engagement / disengagement of the engaging portion 47 with respect to the engaged member 50 will be described later, but briefly, here, the rail unit 10 will be described. When the rear end of the seat-side rail 20 slides outward from the opening 42 of the cover body 41 due to the sliding of the cover body 44, the lid 44 separates from the opening peripheral edge 42a and the rear end of the seat-side rail 20 moves. On the other hand, when the rear end of the seat side rail 20 enters inside from the opening 42 of the cover body 41 while being attached, the lid 44 should be removed from the rear end of the seat side rail 20 and the opening 42 should be closed. It is set.

Next, the operation will be described. The rail cover 40 according to the present embodiment attaches the rear end of the seat side rail 20 that is pulled out from the opening 42 of the cover main body 41 to the cover main body 41 mounted on the rear end of the floor side rail 30. Since the lid 44 to be obtained is detachable, it can be appropriately formed into a size and shape that efficiently cover the rear end of the floor-side rail 30. Therefore, the degree of freedom in design is great, and the demand for space saving can be realized by downsizing the entire shape of the cover itself, and it is possible to prevent interference with other members. Furthermore, it becomes possible to simplify the structure and assembly of the cover.

As shown in FIG. 1, the rear end portion of the floor-side rail 30 is always hidden by the cover body 41 that is mounted so as to cover the outer wall thereof. As a result, there is no danger of a back seat occupant due to burrs or sharp edges at the terminal opening of the floor-side rail 30, and the safety and appearance of the rail unit 10 are improved.
