Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to an adjustment position for adjusting the front and rear position of a vehicle seat, and particularly stores an arbitrary front and rear adjustment position of the seat. It relates to a device having a memory function.

2. Description of the Related Art Conventionally, as a vehicle seat adjusting device of this type, one disclosed in Japanese Utility Model Laid-Open Publication No. 62-133782 is known. This means that the stopper that makes up the adjusting mechanism is detachably fixed with bolts and the like, and the locking plate that can mesh with the rack that makes up the adjusting mechanism can come into contact with the stopper, and the fixed position of this stopper is used as the memory position. I have. In this configuration, at the time of adjusting the front / rear position of the sheet in which the rack and the lock plate are not engaged with each other by operating the adjustment mechanism, the sheet is adjusted to the memory position by abutting the lock plate with the stopper.

(Problems to be Solved by the Invention) However, in the above-described vehicle seat adjusting device, when the memory position is changed because the adjusting mechanism is disposed under the seat, the seat is removed or the seat is under the seat. Then, the position of the stopper must be changed by loosening bolts and the like of the stopper, and the operation is troublesome and troublesome.

Therefore, an object of the present invention is to make it possible to easily change a memory location with a simple operation.

[Structure of device]

(Means for Solving the Problems) The technical measures taken in the present invention in order to solve the above technical liquid problems include an engaging member fixed to the lower rail,
A stopper supported by an upper rail, and a lock that is arranged to face the stopper in the front-rear direction of the seat with the stopper interposed therebetween, and is rotatably supported by the lower rail and slidably in the front-rear direction of the seat and engageable with the engaging member. And a pair of sliders each having a stop wall which can be engaged with the plate and the stopper in the front-rear direction of the seat, and which defines a sliding range of the upper rail with respect to the lower rail in the front and rear directions of the seat.

(Operation) The above technical means operates as follows. The memory position is changed only by sliding the slider with respect to the lower rail by rotating the slider to disengage the lock plate and the engaging member.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the lower rail 1 is fixed to a vehicle floor (not shown) via a bracket 2.
An upper rail 3 is slidably held on the lower rail 1 via a roller 4 and a ball 5, and a seat 6 is fixed on the upper rail 3 via a bracket 15. Further, between the lower rail 1 and the upper rail 3, an adjusting mechanism 7 is disposed outside the both.
The lower rail 1, upper rail 3 and adjustment mechanism 7 are disposed on the left and right sides of the seat 6 in the first illustration.

As shown in FIGS. 1 and 5, the lower rail 1 is formed with a plurality of engagement holes 8 at predetermined intervals along the longitudinal direction. An operation handle 10 is rotatably supported on the upper rail 3 via a bracket 9. A lock plate 11 is fixed to the operation handle 10 so as to rotate integrally with the operation handle 10. The lock plate 11 can be engaged with the engagement hole 8, and is always urged in a direction in which the engagement with the engagement hole 8 is caused by a spring (not shown) disposed between the bracket 9 and the operation handle 10. ing. The engagement between the lock plate 11 and the engagement hole 8 restricts the sliding of the upper rail 3 with respect to the lower rail 1, and the seat 6 is held at an arbitrary position.
The operating handle 10 is provided only on one adjusting mechanism 7, and the other lock plate 11 is pivotally connected to the bracket 9.
13 and is rotatably held by one of the lock plates 11
Are connected to each other via a wire 14.

In the above-described configuration, when the operation handle 10 is rotated, the lock plate 11 is rotated against the urging force of the spring, and the engagement between the engagement hole 8 and the lock plate 11 is released. As a result, the upper rail 3 can slide with respect to the lower rail 1, and the front and rear position of the seat 6 can be adjusted.

A memory mechanism 20 is disposed between one of the lower rails 1 and the upper rail 3 so as to be located outside the both.

 Next, the memory mechanism 20 will be described.

As shown in FIG. 2 to FIG.
A rack 22 having a plurality of meshing holes 21 formed at the same interval as the meshing holes 8 along the longitudinal direction is fixed to the rack. Flanges 22a are formed at both ends of the rack 22, and a shaft 23 is fixed between the flanges 22a. A slider 24 is slidably and rotatably supported by the shaft 23. As shown in FIGS. 6 and 7, the shaft 23 has a longitudinal direction (slider).
(Sliding direction of the slider 24), three parallel grooves 23a, 23b, 23c are formed. The slider 24 has a ball 24a which can be engaged with the grooves 23a, 23b, 23c. By groove
They are always urged in the direction of engagement with 23a, 23b, 23c. The engagement between the grooves 23a, 23b, 23c and the balls 24a makes it possible to hold the slider 24 at three positions with respect to the shaft 23. A notch 23d is formed on the shaft 23, and a protrusion 24c is formed on the slider 24 so as to protrude into the notch 23d.The balls 24a are formed at both ends by engagement of the protrusion 24 with both side walls of the notch 23d. Slider 24 over grooves 24a and 23c
(Rotational range of the slider 24). or,
A lock plate 25 capable of engaging with the engagement hole 21 is provided on the slider 24.
Are fixed so as to rotate integrally.

As shown in FIGS. 2 to 5, a pivot 27 is rotatably supported on the upper rail 3 via a bracket 26, and a stopper 28 is fixed to the shaft 27 so as to rotate integrally. ing. A stopper wall 29 which can be engaged with the stopper 28 is fixed to the slider 24. This stop wall 29
Are divided into two in a form offset by a groove 30 through which the stopper 28 can be inserted to form side end walls 31, 32, and the side end wall 32 is positioned so that the side end wall 31 is located closer to the stopper 28 than the side end wall 32. Offset for The contact surfaces 31a, 32a of the side end walls 31, 32 on the groove 30 side are perpendicular to the stopper 28, and the contact surfaces 31b, 32b on the opposite side are inclined with respect to the stopper 28. It is connected to the wall. A spring 33 is provided between the pivot 27 and the upper rail 3, and the stopper 28 is moved by the biasing force of the spring 33.
Is always urged in the direction of engagement.

The slider 24 having the above-described configuration is disposed at two positions in the front and rear of the shaft 23, and the stopper wall 29 has a symmetric shape.

 Next, the operation will be described.

Memory position setting In the state shown in FIG. 3 to FIG. 5, the grip portion 25a of the lock plate 25 is raised and rotated in the fifth clockwise direction until the ball 24a engages with the groove 23c. As a result, as shown in FIGS. 8 to 10, the engagement between the locking plate 25 and the engagement hole 21 is released, and the stopper 28 is completely inserted into the groove 30 and is brought into contact with the contact surfaces 31a, 32a. Becomes In this state, the operating handle 10 is operated to adjust the seat 6 to a desired arbitrary position. At this time, stop 28
(Stopper 28 and contact surfaces 31a, 32a)
The slider 24 follows the sliding of the upper rail 6 and slides together to an arbitrary position. Thereafter, the lock plate 25 is depressed and rotated in the tenth counterclockwise direction in the drawing until the ball 24a engages with the groove 23b. As a result, the third
As shown in FIG. 5 to FIG. 5, the lock plate 25 and the engagement hole 21 are engaged with each other, and the stopper 28 is inserted halfway into the groove 30 to be in contact with only the contact surface 31a. As a result, an arbitrary position of the desired sheet 6 is stored. In this state, even if the position of the sheet 6 is moved and adjusted to a position other than the arbitrary position, the sheet 6 can be easily returned to the arbitrary position by moving the sheet 6 until the stopper 28 comes into contact with the contact surface 31a.

Temporary release of memory position In the state shown in FIGS. 3 to 5, the lock plate 25 is depressed and the ball 24a is depressed counterclockwise in FIG.
And the groove 23a are engaged. This allows the first
As shown in FIGS. 1 to 13, the stopper 28 is separated from the groove 30, and the contact with the contact surfaces 31a and 32a is released. As a result, the seat 6 can be moved over the memory position, that is, regardless of the memory position. This is particularly effective when the seat 6 is largely moved in the front direction at the time of getting on and off the rear seat of the two-door vehicle. Further, at this time, since the lock plate 25 is engaged with the engagement hole 21, the arbitrary position stored in the lock plate 25 is not shifted or canceled. After this, the seat 6 is returned to the memorized arbitrary position. After returning the seat 6 to the memorized arbitrary position, the lock plate 25 is pulled up and the ball 24a and the groove 23b are clockwise as shown in FIG.
The stopper 28 is rotated until it is engaged, and the stopper 28 and the stopper wall 29 are brought into an engageable state as shown in FIGS. Further, even if the sheet 6 is moved in an arbitrary position direction after the lock plate 25 is pulled up at a position beyond the memory position so that the stopper 28 and the stopper wall 29 can be engaged with each other, the contact surface 31b of the contact surface 28 is not affected. Due to the inclination, the stopper 28 rotates while resisting the urging force of the spring 33, gets over the side end wall 31, and is eventually inserted into the groove 30. As a result, the sheet 6 can be returned to an arbitrary position stored in the memory.

As described above, the memory setting, the memory state, and the temporary release at an arbitrary position can be performed by a simple one-touch operation only by rotating the lock plate 25, and the operability is good. Further, since the memory mechanism 20 is provided independently of the adjusting mechanism 7, the provision of the memory mechanism 20 does not affect the normal performance and is safe. Since the slider 24 is provided at two positions in front and behind, two arbitrary positions can be stored in the memory, which is very convenient especially when two persons having different body shapes are used.

[Effect of the invention]

According to the present invention, there is provided a pair of sliders which are arranged opposite to each other with a stopper in the front-rear direction of the seat, are rotatable, and are slidable in the front-rear direction of the seat. Since the stop plate is provided with the lock plate which can be engaged with the stopper wall and the engaging member, the two positions on the front side and the rear side of the seat can be simultaneously stored by the pair of sliders, and the stored two positions can be stored.
The position can be easily changed.
