See No. 27]. 1 is a lower rail, which is fixed to a floor panel 3 by a lower rail support 2. This lower rail 1 has a gently curved shape that curves upward as a whole, and is fixed in an inclined state with the front side slightly raised higher than the rear side. 4
An upper rail is attached to the lower rail 1 so as to be movable back and forth, and the seat 7 is supported and fixed by a front support part 5 and a rear support part 6 provided on the upper surface of the upper rail. Further, on the upper surface of the upper rail 4, a motor drive mechanism 8 for moving the seat 7 back and forth is further arranged. This motor drive mechanism 8 mainly includes a motor 9 and a worm gear 10.

is set to rotate. The worm gear 10 and pinion gear 11 are engaged with each other, and as the worm gear 10 (7:ITiJ) rotates, the pinion gear 11 rotates to transmit the rotational driving force of the motor 9 in the right angle direction. Next, this pinion gear 1
1 is fitted to the end of a lead screw 12 arranged longitudinally above the upper rail 4, so by rotating this pinion gear 11, the lead screw 12 starts to rotate. The nut housing 13 is rotatably supported from both sides by a rotating pin 16 by a bracket 15 fixed to the lower rail support 2, and the other end of the lead screw 12 is screwed into the nut housing 13. be. Therefore, when the motor 9 is rotated and the lead screw 12 is rotated in a certain direction, the screwing of the lead screw 12 into the NAND housing 13 progresses, and the motor drive mechanism 8
Since the seat itself is drawn toward the nut housing 13 together with the upper rail 4, the seat 7 slides forward F. If the motor 9 is rotated in the opposite direction, the seat 7 will move rearward. Note that the mechanical error between the curved upper rail 4 and the straight lead screw 12 is due to the nut housing 1.
3 is absorbed by rotating around the rotation pin 16.

Since the motor drive mechanism 8 is located above, it is necessary to secure a considerable amount of space above the upper rail 4, and the height of the seat 7 relative to the upper rail 4 must be
Japanese cars, which generally have a lower height than foreign cars, are at a disadvantage in terms of head clearance and other aspects of the vehicle. Since there are many cases, the meshing error in each gear [
Gear backlash] overlapped, and the mechanism as a whole was prone to so-called "backlash." For example, the meshing parts of the coupling 14 and the worm gear IO, the worm gear 10 and the pinion gear 11, and the lead screw 12 and the NAND housing 13,
Furthermore, the fact that the nut housing 13 is supported by a rotating pin 6 in order to absorb the mechanical error between the curved lower rail 1 and upper rail 4 and the linear glue screw 12 may also be a contributing factor to the backlash. Met. It is an object of the present invention to provide a seat slide device that does not require a space between the upper rail and the seat and can move the seat back and forth with little play.

FIGS. 1 and 2 show an embodiment of the present invention. In this embodiment, the upper rail 17 is replaced by the lower rail 18.
A motor drive mechanism 19 that moves the motor back and forth with respect to the front and back is composed of a guide plate 20 and a motor 21. Guide plate 20
is the lower rail 1 to the inside [side] of the lower rail 18.
8 together with the floor panel 2 by the floor bracket 22.
Fixed to 3. This guide plate 20 is the lower rail 1
8 and the upper rail 17, rack teeth 24 are formed on the lower surface thereof, and stopper pieces 25 and 26 are attached to the front and rear of the upper surface, respectively. Also motor 2
1 is attached to the upper surface of the upper rail 17 by a mounting bracket 27, and its rotating shaft 28 is provided with a pinion gear 29 that can freely engage with the rack teeth 24 of the guide plate 20. This mounting bracket 27 also includes a limit switch 3.
0 is provided, and the rotation of the motor 21 is stopped by coming into contact with the stopper pieces 25 and 26. Although only the structure on the left side when facing the front F is shown in the drawing, the guide plate 20 and others are provided on the right side as well, and the structure is substantially the same as that on the left side. However, the motor 21 is not provided on the right side (only another pinion gear that can freely engage with the rack teeth 24 of the guide plate 20 is rotatably attached), and that pinion gear is extended from the motor 21 on the left side. The left and right pinion gears 29 are connected to the flexible wire 31, and the left and right pinion gears 29 are rotated synchronously. Therefore, when the motor 21 is driven and the pinion gear 29 is rotated in the direction of arrow A, the pinion gear 29 and the rack teeth are connected to each other. 2
4 are engaged, the left and right upper rails 1
7 slides forward F by motor:;1, so the seat 32 moves forward F. When the drive of the motor 21 is stopped at an appropriate position, the seat 32 is positioned at that position. Also, even if you move it to the front F, seat 3
When the motor 2 reaches the forwardmost position, the limit switch 30 comes into contact with the front stopper piece 25, and the motor 21 is stopped and automatically positioned at the forwardmost position. If the pinion gear 29 is rotated in the opposite direction, the seat 32 can be moved backward I\ by the action opposite to that described above, and as before, the limit switch 30 is moved to the rear stopper piece 26. When it comes into contact with the seat 32 at the rearmost position, the rotation of the motor 21 is stopped and the seat 32 is positioned at the rearmost position. In this way, in this embodiment, the three-motor drive mechanism 19
, that is, the guide plate 20 and the motor 21 are connected to the lower rail 18
Since the motor drive mechanism 19 does not require space and the height h of the seat 32 relative to the upper rail 17 can be set low, the occupant's head Clearance becomes an advantage. Furthermore, since the only gear mechanism that requires a meshing error is the combination of the pinion gear 29 and the rack teeth 24, overall there is little "backlash" and sharp back-and-forth movement is possible. In addition, although the lower rail 18 and the lower rail 17 having a curved shape in which the central portion is curved upward in the same manner as the conventional example have been described above, this invention is disclosed in Japanese Patent Application Laid-Open No. 60-672.
It is also possible to adapt to a downwardly curved swing seat such as that known in No. 35. Also, contrary to the embodiment, the guide plate 20 is connected to the upper rail 17, and the motor 21
'c It may be provided on the lower rail 18. FIGS. 3 and 4 are diagrams showing other embodiments of the present invention. Note that explanations that overlap with the previous embodiments will be omitted. In this embodiment, a motor drive mechanism 40 is composed of a guide plate 41 and a motor 21. The guide plate 41 is fixed to the bottom surface of the lower rail 18, and has one end protruding toward the inside side (c). This guide! Fj, 41 has the same curved shape as the lower rail 18 and upper rail 17, and has rack teeth 42 formed on its lower surface. Stopper pieces 43 are attached to the front and rear of the lower rail 18, respectively. Further, the motor 21 is attached to the upper surface of the upper rail 17 by a mounting bracket l-44, and the pinion gear 29 is connected to the rack tooth 44.
2 in a freely engageable state. Reference numeral 45 denotes a limit switch, which is supported by screws 47 on a mounting bracket 46 provided on the upper rail 17, and is connected to the stopper piece 43.
By coming into contact with , the rotation of the motor 21 is stopped. Note that the operational relationship is substantially the same as in the previous embodiment.

行えるものである。Since the seat slide device according to the present invention has the content as described above, the height of the seat relative to the upper rail can be lowered, and the head clearance for the occupant seated on the seat can be widened. In addition, since the only gear mechanism that requires meshing error is a combination of a binion gear and rack teeth, overall there is little "backlash" and the sheet can be moved back and forth sharply. Further, since the guide plate has a curved shape corresponding to the lower rail and the upper rail, smooth back and forth movement can be performed without any mechanical strain.
