Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a seat used in a vehicle or the like, and more specifically to the structure of the rear end of a slide rail.

[Prior Art] Examples of conventional sheets include those shown in FIGS. 1 to 3 (see Japanese Utility Model Application Publication No. 57-50247). In the figure, 1 is a seat, and a seat cushion 5 is moved in the front and back direction by vertical slide rails 3 and 4. Rear brackets 7 and 8 are fixed to the rear ends of the vertical slide rails 3 and 4 by a method such as rivets or projection welding, either singly or in combination. The rear brackets 7 and 8 have ribs 7a and 8a rising upward, and are made of a resin cover for catching or pinching the shoes of a person sitting on the rear seat (not shown) of the seat 1. 9 was covered.

However, since the seat 1 must move in the longitudinal direction, the cover 9 only covers the lower portions of the slide rails 3 and 4 of the rear brackets 7 and 8. Therefore, in the state shown in Fig. 1 where seat 1 has moved to the frontmost position,
Since the upper ends of the ribs 7a, 8a of the rear brackets 7, 8 and the rear ends of the slide rails 3, 4 were exposed, the shoes S of the person sitting in the rear seat were exposed, as shown in FIGS. 2 and 3. There was a problem in that the front or sides of the slide rails 3, 4 or the panel edges of the rear brackets 7, 8 were scratched.

[Purpose of the invention] Therefore, the purpose of this invention is to prevent shoes from hitting and damaging the edges.

[Structure of the invention] In order to achieve this purpose, the rib is provided with a curved portion where the rear end surface of the lower rail of the slide rail is a tangent plane,
Alternatively, a curved portion is formed to cover the rear end surface of the lower rail.

[Example] This invention will be explained below based on the drawings.

FIGS. 4 to 7 are diagrams showing an embodiment of this invention. In the drawings, parts or members that are the same or equivalent to those in the prior art are denoted by the same reference numerals and redundant explanations will be omitted.

The seat cushion 5 is attached to the slide rails 3 and 4 via upper rail brackets 11 and 13. Specifically, the upper rail brackets 11 and 13 are attached by rivets or welding to upper rails 3b and 4b that constitute the slide rails 3 and 4 together with the lower rails 3a and 4a, respectively. Further, the ribs 16, 18 of the rear brackets 15, 17 are attached to the vertical types 3c, 4c at the rear end portions of the lower rails 3a, 4a.
The flat parts 16a and 18a of the flat parts 16a and 18a are in contact with each other, and
Curved portions 16b and 18b connected to 18a have rear end surfaces 3d and 4d of lower rails 3a and 4a as tangent planes. Therefore, as shown in FIG.
The curved portions 16b, 18b of the lower rails 3, 4 extend smoothly without any edge portions to the rear end surfaces 3d, 4d of the lower rails 3, 4.

Note that the ribs 16 and 18 are connected to the lower rail 3a,
Although only the vertical walls 3c and 4c of 4a have been described, as shown in FIGS. 4 and 5, the flat portion 16
a, 18a and the curved portions 16b, 18b can also be extended along the lower rails 3a, 4a,
In this case, there are fewer edge parts and there is less chance of damaging the shoes. Moreover, the curved portions 16b, 16
c, 18b, and 18c can also be formed by overlaying or the like.

FIG. 7 shows curved portions 16b and 18 shown in FIG.
Curved portions 16c and 18c are shown as a modified example of b.
c, covering the surface along 4c.

The seat 1 constructed in this manner is completed by attaching the rear brackets 15, 17 to the floor F with bolts 19 and covering them with the cover 9, thereby making the seat cushion 5 freely movable in the front-rear direction.

Next, the effect will be explained.

Since the seat cushion 5 can be moved in the front-rear direction, when the seat cushion 5 moves forward as shown in FIG. 4, the rear ends of the lower rails 3a, 4a are exposed. If a person sits in the rear seat under such severe conditions and stretches their legs forward, the shoes S will come into contact with the cover 9 or the rear brackets 15 and 17.
They are often brought into contact. But most of all,
Lower rails 3a and 4a where shoes S hit and cause problems
The surfaces along the vertical walls 3c, 4c of the rear end surfaces 3d, 4d have no edges, and the shoe S has a smooth curved portion 16.
b, 18b so it won't get scratched.

This is the curved portion 16c, 1 as shown in FIG.
The same applies to the modification example 8c.

[Effects] As explained above, according to this invention, since the rib is configured to form a curved portion on which the rear end surface of the lower rail of the slide rail is a tangential plane or a curved portion that covers the rear end surface of the lower rail, the edge portion is It is safe, does not damage the shoes, is safer, and is more aesthetically pleasing.

Claims (1)

[Claims for Utility Model Registration] Two upper rails are fixed in parallel to the seat cushion, and a lower rail, which is one of the vertical slide rails that makes the seat cushion freely movable, is held from the inside. In the seat, the rear bracket is assembled to hold the vertical slide rail on the floor and has a rib, and the rear bracket is fixed to the vertical wall of the rear end of the lower rail with the rib in contact with the vertical wall. The rib of the rear bracket includes a flat part that makes surface contact with the vertical wall of the lower rail, and a curved part that is connected to the flat part so that the rear end surface of the lower rail becomes a tangential plane, or a curved part that covers the rear end surface of the lower rail.
