Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a seat slide device for moving a seat back and forth.

<Prior Art> As a conventional seat slide device, there is one shown in FIG. 5, for example. 1 is a seat, consisting of a seat cushion 2 and a seat back 3,
A pair of left and right slide rails 5 are provided on the lower surface 4 of the seat cushion 2. Each of the slide rails 5 is a pair of upper and lower rails in which the seat side rail and the vehicle body side rail can be mutually lubricated, and the seat 1 can be moved back and forth by sliding of the slide rails 5. Note that 6 is a protective cap that prevents the rear end 8, which fixes the slide rail 5 to the floor with bolts 7, from being exposed.

<Problems to be solved by the invention> However, in such a conventional seat slide device, although the rear end portion 8 of the slide rail 5 is prevented from being exposed by the protective cap 6, the rear end portion 8 of the slide rail 5 is prevented from being exposed. Since most of the other parts of the slide rail 5 were left exposed, the feet of the rear seat occupants interfered with the exposed parts of the slide rail 5, and the occupant's shoes and other parts were soiled by the lubricating oil etc. of the slide rail 5. Since the slide rail 5 is exposed, dust and dirt are likely to adhere to it.
There is a risk that the smooth back and forth movement of the seat 1 will be hindered, and maintenance to remove such deposits is also troublesome.

Therefore, in order to prevent interference between the feet of rear seat occupants and the slide rails, the applicant first covered the gaps between each exposed portion of the slide rails 5 and each rail to follow the back and forth movement of the seat. We have proposed a safety device for automobile seat slides that includes a sheet-like cover body (see Japanese Utility Model Application Publication No. 100830/1983).

The present invention is related to such previous proposals, and the entire slide rail is covered with a cover body,
Furthermore, it is an object of the present invention to provide a seat slide device in which a portion of the cover body can also be used as a footrest for a rear seat passenger.

<Means for Solving the Problems> In order to achieve the above-mentioned purpose, the seat slide device according to this invention has the entire slide rail disposed on the lower surface of the seat cushion to allow the seat to move back and forth. , a cover body that has an elastic part that follows the longitudinal movement of the seat and has rigidity at least in the rear part so as to double as a footrest for rear seat passengers,
It is covered.

<Function> Since the entire slide rail is covered by the cover body, it is difficult for dust and other substances to adhere to the slide rail, and since the cover body has an expandable part that follows the back and forth movement of the seat, Even when the seat is moved back and forth, the entire slide rail remains covered without being exposed.Furthermore, at least the rear part is made rigid, so even when rear seat passengers put their feet on the cover, it does not deform. It is possible to use the rear part as a footrest.

<Example> The details of this invention will be explained below based on FIGS. 1 to 4. Incidentally, the same reference numerals are given to the parts common to the conventional ones, and redundant explanation will be omitted.

1 to 3 are diagrams showing an embodiment of this invention.

A cover body 9 has a flat box shape that covers the entire slide rail 5. This cover body 9 is a base cover made of hard resin, which has slightly wide inclined parts 10a, 10b and vertical parts 10c, 10d continuous thereto on the front and rear parts, and vertical parts 10e on the left and right parts. 10, and an upper cover 11 made of flexible resin that is engaged with the upper side of the base cover 10 to form an upper surface portion. A quadrilateral opening 11 a is provided in the center of the upper surface of the upper cover 11 , and the edge of this opening 11 a is fixed to the lower surface 4 of the seat cushion 2 . Furthermore, since bellows portions 11b and 11c are formed as "expandable parts" in the portions of the upper cover 11 corresponding to the front and rear of the opening 11a,
This bellows part 1 follows the back and forth movement of the seat 1.
1b and 11c can be expanded and contracted mutually.

Next, the action will be explained.

Normally, the slide rail 5 is entirely covered by the cover body 9, so that dust and other substances do not adhere to the slide rail 5, and the rear seat passenger's feet 12 and the slide rail 5 do not come into direct contact. It doesn't get dirty either. For example, even if the seat 1 is moved forward [see FIG. 1] or backward [see FIG. Since the slide rail 5 expands and contracts following the movement, the entire slide rail 5 remains covered by the cover body 9, and the slide rail 5 is not exposed and dust does not enter the cover body 9.

In addition, the base cover 10 of the cover body 9 is made of hard resin, and the inclined part 10b and vertical part 10d, which serve as the "rear part", have rigidity, so that they do not deform even if the rear seat occupant places his/her feet 12 on them as a footrest. The rear seat occupant can enjoy a comfortable footrest feeling regardless of the front or back position of the seat 1.

FIG. 4 is a diagram showing another embodiment of this invention. In the cover body 13 of this embodiment, instead of the bellows portions 11b and 11c in the previous embodiment, a slide plate 14 is formed by overlapping a plurality of strips in a substantially horizontal manner as an "expandable section" and is extendable and retractable.
b, 14c are adopted in the front and rear portions of the opening 14a of the upper cover 14. Since these slide plates 14b and 14c have few irregularities, the slide plate 1
Cleaning and maintenance of 4b and 14c themselves is easy and they look good. The other configurations and functions are the same as those in the previous embodiment, so explanations will be omitted.

In the above explanation, the cover bodies 9 and 13 made up of the base cover 10 and the upper covers 11 and 14 were shown as examples of "cover bodies"; It may be an integral piece as long as it can keep the entire cover covered, and it is also free to use stretchable cloth or other material for the "stretchable part". In addition, the "rear" part of the cover body does not need to be made of rigid material itself, but should be reinforced from the inside or outside with a separate rigid part to prevent it from being deformed by the feet of the rear seat occupant. You can.

<Effects> Since the seat slide device according to this invention has the content as described above, various effects such as those described below can be expected.

(a) There is no direct interference between the rear seat occupant's feet and the slide rail, so shoes and other items are not soiled by the slide rail; (b) Dust and other objects are less likely to adhere to the slide rail, so the slide (c) The rear part of the cover body can be used as a footrest for rear seat passengers, which improves the riding comfort of rear seat passengers. (d) The overall appearance of the seat slide device is improved.
