形し易くなる欠点があつた。<Prior art and its problems> As shown in Figs. 1 and 2, a conventional seat adjuster consists of a pair of fixed side guide rails 1 and a seat 2 made of channel-shaped steel fixed to the floor of an automobile. A movable guide rail 3 made of a dovetail channel material that is fixed to both sides of the side, engages with the fixed guide rail 1 in an uneven manner, and slides in the longitudinal direction, and both sides of each guide rail 1, 3. Ball 4 interposed between sliding bending surfaces 1A and 3A
and a roller 13 interposed between the central sliding surfaces 1B and 3B. Further, a side plate 5 having an L-shaped cross section is fixed to the movable guide rail 3 to position both sides of the seat 2 and to fix a belt anchor 6. In the seat adjuster with this structure, the occupant O holds the seat belt 7 with the belt anchor 6.
When the occupant O moves in the direction of the arrow, since the rear protruding end of the movable guide rail 3 separates from the fixed guide rail 1 with the seat 2 moved backward,
A large tensile load is applied to the belt anchor attachment end of the side plate 5. As a result, when a large impact is applied to the protruding end of the guide rail 3, the protruding end of the guide rail 3 tends to deform from the joint end with the stationary guide rail as a starting point, as shown by the imaginary line in FIG. 1b.
《考案の目的》
本考案は、従来のシートアジヤスタに格別な補

In a seat adjuster equipped with a guide rail, the rod is interposed in the longitudinal direction of the sliding surface of each guide rail, runs on the fixed guide rail together with the movable guide rail, and extends to the rear end of the movable guide rail. The present invention is characterized by comprising a return spring having one end connected to the rod and the other end being fixed to the stationary guide rail, and a belt anchor connected to the rear part of the movable guide rail.

In addition, in the figures, the same parts as in the conventional art are given the same reference numerals for explanation. Each guide rail 1, 3
In place of the conventional balls, a pair of rods 10 are interposed on the sliding and bending surfaces on both sides. One end of a tension coil spring 11 is connected to the tip of each rod 10, and an auxiliary rail 12 is integrally fixed to the rear end of each rod 10 by welding or the like.

方向へ摺動復帰するのを助ける。 The other end of the spring 11 is hooked and locked onto a locking portion 1a formed on the side of the guide rail 1. Furthermore, a locking portion 12a is formed by cutting and raising the auxiliary rail 12. This locking portion 12a is matched with a locking protrusion 12a' formed on the movable guide rail 3. FIG. 4 shows the origin position of the movable guide rail 3 in the seat adjuster constructed as described above. When the movable guide rail 3 is moved from this position as shown by the arrow, the rod 10 moves together with the guide rail 3 while charging the tension coil spring 11. Therefore, the protruding end of the movable guide rail 3 from the fixed guide rail 1 is reinforced by the rod 10 serving as the center core. Also, at this time, the spring 11 expands greatly, and the rod 10 and movable guide rail 3
Acts as a biasing force to return to the original position. This biasing force compensates for the sliding resistance at the time of return. That is, when the rod 10 is interposed on the sliding surface instead of the conventional ball, the contact changes from a point contact to a line, which increases the sliding resistance. This resistance becomes an obstacle especially when returning, but this resistance is reduced by the tension of the spring 11 that has already been spring-charged when the movable guide rail 3 moves in the direction of the arrow, and the movable guide rail 3 moves in the direction of the arrow. Helps slide back in the opposite direction.

3, it is also possible to interpose a ball in the space between the fixed guide rail 1 and the movable guide rail 3 on the front side of position A.
《考案の効果》

きる。《Effects of the invention》 In this invention, the structure is such that the rod is placed on the protruding part of the movable guide rail, so there is no decrease in the rigidity of the protruding part, and the increase in sliding resistance due to the use of rods instead of balls is due to the spring. Compensated. Therefore, sufficient rigidity can be provided and smooth sliding operation can be performed without requiring special reinforcement measures for each guide rail.
