The specific embodiment
As shown in Figure 4, the situation at foreign object shown in Figure 18 is blocked increases plastics swash plate 11 in the following rail of slide rail, and plastics swash plate 11 adopts the mode of buckles to be fixed on the following rail 12.
As shown in Figure 5, the front of plastics swash plate 11 has an inclined-plane 11a and a long plane 11b.The long engaging member 11c of front end and rear end a plurality of stub fastener 11d are stretched out in the back side of plastics swash plate 11.
As shown in Figure 6, when slide rail locking plate 15 moves to the end position of slide rail with the last rail 14 of slide rail, locking plate 15 moves to complete released state 15b by lockup state 15a, between the appearance profile of plastics swash plate 11 and the locking plate 15 enough gaps is arranged, and does not interfere the motion of locking plate 15.
As shown in Figure 7, be formed with front end square hole 12a and a plurality of rear end square hole 12b on the following rail 12, the long engaging member 11c of front end square hole 12a and front end buckle, rear end square hole 12b and stub fastener 11d buckle.
As shown in Figure 8, the situation at foreign object shown in Figure 3 is blocked increases by a plastics swash plate 13 in the following rail of slide rail.As shown in Figure 9, transverse plane 13a before the front of plastics swash plate 13 has, a long plane 13b and the short plane 13c in a rear end, transverse plane 13a and the short plane 13c in rear end before long plane 13b connects.Short plane 13c is identical with the height of link stopper 17.The back side of plastics swash plate 13 is extended with front end fixed card fastener 13d, rear end fixed card fastener 13f and middle Elastic buckle spare 13e.
As shown in figure 10, when slide rail locking plate 15 moves to the end position of slide rail with the last rail 14 of slide rail, locking plate 15 moves to complete released state 15b by lockup state 15a, between the appearance profile of plastics swash plate 13 and the locking plate 15 enough gaps is arranged, and does not interfere the motion of locking plate 15.
As shown in figure 11, be formed with front end circular hole 12c, middle square hole 12a and rear end square hole 12b on the following rail 12.Front end engaging member 13d and front end circular hole 12c buckle, middle Elastic buckle spare 13e and middle square hole 12a buckle, rear end square hole 12b and rear end engaging member 13f buckle.
(a) of Figure 12 shown the installation process of embodiment shown in Figure 8 successively to (d).Middle Elastic buckle spare 13e contact is compressed distortion behind the rail inside face 12d down, enter down the circular hole 12c and square hole 12b of rail fully as front and back end fixed card fastener 13d, 13f after, after move plastics swash plate 13 square hole 12a in the middle of middle Elastic buckle spare 13e enters into.Middle Elastic buckle spare 13e provides an elastic force, and plastics swash plate 13 and following rail are linked closely.
At the situation that foreign object shown in Figure 2 is blocked, punching press forms slope protrusion 12e on following rail, and slope protrusion 12e is between the plastics protection end cap 10 and slide rail tommy 16 of following rail end.Shown in (a) among Figure 13, also be provided with swash plate shown in Figure 8 13 on the following rail.
As shown in figure 14, foreign object 11 is released out slide rail according to the direction shown in the arrow among the figure by last rail end cap 7 when moving behind the seat.
Shown in Figure 15, foreign object 11 is released according to the direction shown in the curved arrow when moving behind the seat support by last rail end cap 16, and via going out slide rail after the slope protrusion 12e guiding.
