Problems solved by technology

[0006] If the lower rail 2 of the conventional seat slide 1 is elongated as described above, it is troublesome to process the corresponding part due to dimensional error or the like.
In addition, if you want to maintain the length to bear the load, you will increase the weight, which is very disadvantageous
In addition, if a peeling load is applied upward to the side of the upper rail 5 due to an impact load or the like, the upper portion of the lower rail 2 opens, and there is a risk of lowering the peeling strength.
In addition, if the lower rail 2 is installed on the side of the floor surface of the vehicle body to prevent the floor surface from falling downward into the interior of the lower rail 2 from the opening portion of the lower rail 2, the smooth sliding operation of the upper rail 5 cannot be achieved.

[0022] As is well known, a seat sliding device 11 is provided between a seat main body (not shown) inserted on a vehicle body floor through a seat cushion, a seat back or the like and a vehicle body floor surface for supporting the seat main body so that it can be positioned on the seat. Swipe freely in the vertical direction.

[0023] The seat sliding device 11 has a lower rail 12 installed longitudinally on the seat installation floor surface, and an upper rail 13 which guides and supports the upper rail 13 so as to freely slide longitudinally, and the upper rail 13 is installed on the side of the seat body. In addition, according to figure 2 In the first embodiment shown, the guide rail 12 is arranged so as to be embedded in the groove portion 14 a of the carpet 14 . The seat slider 11 is formed by extrusion from a light alloy such as aluminum die-casting, magnesium alloy or the like. In this case, the seat slider 11 may be a hard synthetic resin molding.

[0041] Refer below Figure 6 and 7 illustrate the second embodiment of the present invention. Figure 6 It is a cross-sectional view of the second embodiment of the present invention, and Fig. 7 is an exploded oblique view of the lower guide rail of the second embodiment of the present invention. In this case, with figure 2 Corresponding components in to 5 adopt the same reference numerals.

[0042] The seat slider 11 has a lower rail 12 extending longitudinally along the vehicle body floor surface 1 and an upper rail 13 which guides and supports the upper rail 13 so as to freely slide in the longitudinal direction and which is installed and fixed on the side of the seat body. The lower rail 12 is fixed to the vehicle body floor surface 1 by bolts 31 or the like.

[0043] The lower rail 12 and the upper rail 13 of the seat slide 11 are formed from extruded products of light alloy such as aluminum die-casting, magnesium alloy or the like. In this case, the lower rail 12 a...

Abstract

First hook portions are formed at front end portions in a side of an opening portion of a main body portion in a long lower rail, and second hook portions are formed in lower portions of both side portions in the main body portion. First engagement portions engaged with the first hook portions in the long lower rail are formed in upper walls in an upper rail. Projection portions are formed in the first engagement portions so as to protrude to the side of the first hook portions. Second engagement portions engaged with the second hook portions in the long lower rail are formed in front end sides of both side portions of the main body portion in the upper rail.

Description

technical field [0001] The present invention relates to a seat sliding device, and more particularly to a seat sliding device comprising a lower rail installed along a longitudinal direction of a floor surface on which a seat is installed, and an upper rail which guides and supports the upper rail so as to move along the longitudinal direction It slides freely, and the upper rail is mounted on the side of the seat body. Background technique [0002] Generally, a seat of a vehicle has a seat body composed of a seat cushion, a seat back standing on the back so as to be freely rotatable and adjustable, and the like, and the seat supports the cushion by a longitudinal sliding mechanism or constitutes a seat on the floor surface of the vehicle body. The analogue of the main body, thus has a structure that can be adjusted for free sliding in the longitudinal direction of the body and has a configuration that allows various changes to the arrangement of the seats in the passenger c...
