式（電動式）のシートスライド装置に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a seat slide device that moves an automobile seat in the front and rear directions, and more specifically, a power-type (electrically powered) seat slide device that moves the seat in the front and rear directions by the force of a motor. This invention relates to a seat slide device of formula (2).

スペースの確保を図るしか方法法がなかつた。(Prior Art) When getting in and out of the rear seat of a two-door car, it is widely practiced to secure a space for getting in and out by folding the seat back of the front seat forward and moving the entire seat forward. In addition, automobiles employing a seat slide device having a mechanism (walk-in mechanism) that automatically moves the entire seat forward when the seat back is folded forward are also becoming popular. However, this applies to cars with a manual seat slide device; in cars with a power seat slide device, you press a switch to drive the motor and seat the seat in the same way as normal seat position adjustment operations. The only option was to move the entire vehicle forward to create more space for boarding and alighting.

ものである。(Means for Solving the Problems) The present invention solves the above problems by slidably fitting an upper rail into a lower rail fixedly installed on the floor side, and a screw bar that is moved in the axial direction by a motor. is arranged in parallel with the upper rail, the screw bar and the upper rail are connected, and the motor and the lower rail are connected so that the upper rail can be pushed by the screw bar, and the seat is rapidly forwarded. In some cases, the motor is configured to be disconnected from the lower rail.

る。(Function) In the seat slide device of the present invention, when adjusting the seat position, the screw bar is connected to the upper rail, and the motor is connected to the lower rail. Therefore, by moving the upper rail using the force of the motor, the position of the seat can be adjusted in the longitudinal direction. On the other hand, when performing rapid forwarding, the connection between the motor and the lower rail is released. This results in
The upper rail moves forward, and the seat also moves forward together with the upper rail. This movement is independent of the rotational speed of the motor, so it can be performed at high speed.

方向（前後方向）に移動することになる。 In FIGS. 1 and 2, 1 is a lower rail fixed to the floor side, 2 is an upper rail fixed to the seat side, and these are slidably fitted. A lower rail mounting bracket 3 for fixing the lower rail 1 to the floor is fixed to the lower surface of the front and rear parts of the lower rail 1. Furthermore, a wedge-shaped locking member 4 is fixed to the lower surface of the intermediate portion of the lower rail 1 toward the front. 5 and 6 are arm brackets fixed to the upper surface of the front and middle parts of the upper rail 2, respectively, in a state that projects sideways;
The front end of the screw bar 7 is attached to the arm bracket 5.
The central portion is slidably supported by an arm bracket 6. On the other hand, the motor mounting bracket 9 to which the motor 8 is attached is rotatably supported by the screw bar 7, and is biased to rotate clockwise in FIG. The portion 9a is fitted into a lock groove 4a provided on the inclined lower surface of the lock member 4.
The rotation of the motor 8 causes the screw bar 7 to move in the front and back direction (in the direction of the arrow). As an example of a mechanism for converting the rotation of the motor 8 into the movement of the screw bar 7 in the front-back direction, a worm is coupled to the output shaft of the motor 8, a worm wheel is engaged with the worm, and a female thread is installed in the center of the worm wheel. There is one that is cut in the axial direction and the screw bar 7 is screwed into it. In addition, in the case of this mechanism, the worm wheel is restricted from moving in the axial direction. Therefore, when the motor 8 is driven, the worm and the worm wheel rotate, and the screw bar 7 moves in the axial direction (back and forth direction).

いる。 Reference numeral 10 denotes a bracket for mounting an operating lever, which is fixed to the lower surface of the lower rail 1 so as to protrude laterally and stand up. A substantially L-shaped operating lever 11 is pivotally attached to this bracket 10 with a pin 12, and the operating lever 11 is connected to a first
When it is turned counterclockwise in the figure (when it is pushed down), the rotating tip 9b of the motor mounting bracket 9 that is in contact with it moves downward. Moreover, the arm bracket 6 and the bracket 3
(on the front side), there is a tension spring 1
3 is tensioned, and this tension spring 13 urges the upper rail 2 forward.

位置にて停止する。 First, under normal use, the rotation intermediate portion 9a of the motor mounting bracket 9 is fitted into the lock groove 4a of the lock member 4, and the motor 8 and the lower rail 1 are in a connected state. Therefore, when the motor 8 is rotated forward or backward using a switch (not shown), the screw bar 7 moves forward or backward relative to the motor 8, and the upper rail 2 integrated with the screw bar 7 moves. That is, lower rail 1
An upper rail 2 slides on the top in the front-rear direction, allowing adjustment of the seat's position in the front-rear direction. This operation is exactly the same as a conventional power seat slide device. Next, when it becomes necessary for a passenger to get on or off the rear seat, the operating lever 11 is pushed down. As a result, the rotating tip 9b of the motor mounting bracket 9 is pushed downward, and the motor mounting bracket 9 rotates counterclockwise in FIG. 9a and lock member 4
is released from the lock groove 4a (see Fig. 2). Therefore, the upper rail 2 is rapidly moved forward by the force of the tension spring 13 and stops at the foremost position.

状態即ち通常の使用状態に戻る。 To return to normal use from the frontmost position, simply raise the seat back and push it back.
As a result, the rotating intermediate portion 9a of the motor mounting bracket 9 falls (fits) into the locking groove 4a of the locking member 4 again, and the seat slide device returns to the locked state, that is, the normal use state.
