それがあつた。 This upper rail slides on the lower rail by the screw rod moving inside the nut material of the lower rail, but due to various loads generated on the screw rod etc., the nut material into which the screw rod is screwed and the bracket of the lower rail slide. When the fixed state is weakened, the nut material falls off from the bracket due to an unexpected load, such as the load at the time of a collision, and as a result, the engagement state between the screw rod and the lower rail to which the nut material is fixed is released, and the upper rail is attached to the lower rail. There was a risk that the top might slide unexpectedly.

On the other hand, a bracket 11 is provided on the upper surface of the upper rail 2 at approximately the center thereof in the longitudinal direction, extending in the direction of the locking piece 10 of the lower rail 1. The tip of this bracket 11 is curved toward the floor surface, and a notch 12 is provided approximately in the center. A shaft member 13 is rotatably attached to the curved portion of the bracket 11, and is biased in one direction by a spring member 14. and,
This shaft member 13 has a locking piece 1 perpendicular to the shaft.
5 is fixed approximately at the center. This lock piece 15 is
A claw portion 16 is formed at the lower part of the lower rail 1.
There is a bracket 11 on the upper part facing the locking piece 10 of
A protruding piece 17 is formed that protrudes from the notch 12 . Shaft material 1 to which this lock piece 15 is attached
3 is biased by a spring member 14 so that the claw portion 16 of the locking piece 15 moves in the direction of the locking piece 10. Furthermore, a rotary plate 18 is pivotally supported on the upper surface of the bracket 11 so as to be rotatable on a horizontal plane.
One end 18a of the lock piece 15 is removably engaged with the protrusion 17 of the lock piece 15, and as the rotating plate 18 rotates, the one end 18a of the rotating plate 18 and the lock piece 15
The locked state with the protrusion 17 is released. On the other hand, a weight 19 is fixed to the other end 18b of the rotating plate 18. The length between the weight 19 and the pivot point of this rotary plate 18 is set longer than the length between the pivot point and the one end 18a, so that the weight 19 of the rotary plate 18 is easily moved by the load in the front and back direction. , this rotary plate 18 is formed to be easily rotatable.

8a is engaged with the protrusion 17 of the lock piece 15, and the claw part 16 of the lock piece 15 and the engagement piece 10 of the lower rail 1 are engaged with each other.
is in an unlocked state, and the upper rail 2 is moved to the lower rail 1 by the driving force of the drive motor.
slide on top. When an unexpected load, such as a load at the time of a collision, occurs on this slide rail, the reaction force causes the weight 19 of the rotating plate 18 to move in the direction of the reaction force, and the rotating plate 18 rotates thereby. one end 1
8a and the protrusion 17 of the lock piece 15 are released. Along with this, since the shaft member 13 to which this lock piece 15 is fixed is biased by the spring member 14, the claw portion 16 of the lock piece 15 moves in the direction of the locking piece 10 of the lower rail 1, and this The claw portion 16 locks into a square hole 10a formed in the locking piece 10 of the lower rail 1. As a result, the upper rail 2 is locked to the lower rail 1, and the sliding of the upper rail 2 is restricted, so the seat is also locked without moving, improving the safety of the occupants. Moreover, since the upper rail 2 can be locked to the lower rail 1 by this locking piece 15, the lead screw 4 and the nut material 9 can be locked together.
There is no need to manufacture them strongly, and the manufacturing cost of these can be reduced. Furthermore, since the lead screw 4, nut material 9, etc. can be downsized, the space between the seat and the vehicle body is expanded, and this expanded space can be used for other purposes.

A locking piece having a locking hole formed therein is provided, and a locking piece that is removable in the locking hole of the locking piece is attached to the upper rail, and one end restricts the movement of the locking piece in the direction of the engaging hole. A rotary plate having a weight at the other end is provided on the upper rail so as to be horizontally rotatable, and the rotary plate rotates due to the load at the time of a collision to release the restriction on the movement of the lock piece. This locking piece can be locked into the locking hole of the lower rail to lock the upper rail. Therefore, the slide rail is locked in the event of a collision due to the double locking of the locked state by this locking piece and the locked state due to the threaded engagement of the screw rod and nut material, thereby improving the safety of the occupants. Furthermore, since only a small load is generated on the screw rod, etc., it is possible to downsize the screw rod and the like, thereby reducing the manufacturing cost. Furthermore, since the screw rods and the like are made smaller, the space between the seat and the vehicle body is expanded, and this space can be used for other purposes.
