<< First Embodiment >>
<About the outline configuration of the slide rail device (slide rail device for vehicles) 4>
First, the configuration of the slide rail device 4 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6. In the following description, when each direction such as front-back, up-down, left-right, etc. is shown, it means each direction shown in each figure.

With reference to FIGS. 1 to 3, the slide rail device 4 according to the present embodiment is applied to a seat (vehicle seat) 1 which is a driver's seat of a right-hand drive vehicle. The seat 1 includes a seat back 2 forming a backrest portion of a seated occupant, a seat cushion 3 forming a seating portion, and a headrest (not shown) forming a headrest portion.

The slide rail device 4 has a pair of left and right slide rails 10 that can adjust the position (seat position) of the seat 1 in the front-rear direction. Further, the slide rail device 4 has a memory mechanism 20 that stores the position before the change of the seat position and operates so that the seat position can be easily returned to the position before the change.

A pair of left and right slide rails 10 are provided between the seat cushion 3 and the floor F (vehicle body) of the vehicle. Each slide rail 10 has a lower rail 11 fixed on the floor F and an upper rail 12 assembled so as to be slidable only in the front-rear direction with respect to the lower rail 11 and fixed to the bottom surface of the seat cushion 3. , Have.

Each of the lower rails 11 has a rail shape extending in a long shape with a substantially uniform cross-sectional shape in the front-rear direction. Specifically, each of the lower rails 11 has a flat plate-shaped bottom plate portion set on the floor F with its surface facing in the height direction, and substantially inverted U inward from the left and right side edges of the bottom plate portion. It is formed in a cross-sectional shape having a pair of left and right lower side fins extending in a shape bent back in a shape.

Each upper rail 12 also has a rail shape extending in a long shape with a substantially uniform cross-sectional shape in the front-rear direction. Specifically, each upper rail 12 has a flat top plate portion set under the seat cushion 3 with its surface facing in the height direction, and substantially U downward and outward from the left and right side edges of the top plate portion. It is formed in a cross-sectional shape having a pair of left and right upper-side fins extending in a bent-back shape.

Each upper rail 12 is assembled into each lower rail 11 so as to be slidable only in the front-rear direction by being inserted into the inside from the opening end on either side in the longitudinal direction. Specifically, each upper rail 12 is passed through each lower rail 11 in a space in which the left and right upper fin portions are bent back in an inverted U shape of the left and right lower fin portions. It is assembled to.

As a result, each upper rail 12 is assembled to each lower rail 11 so that the left and right upper side fins are engaged with the inverted U-shaped bent back portion of each lower side fin. By the above engagement, each upper rail 12 is set with respect to each lower rail 11 so as not to come off in each of the up, down, left, and right directions.

Specifically, between the upper rails 12 and the lower rails 11, resin shoes and steel balls (rolling bodies) (not shown) are set at the four corners of their cross sections. As a result, each upper rail 12 is guided to each lower rail 11 so that it can slide smoothly only in the front-rear direction without rattling in each of the up, down, left, and right directions.

Each of the upper rails 12 is provided with a lock mechanism 10A that locks the slide in the front-rear direction by engaging each lower rail 11 with a lock spring (not shown). Each lock mechanism 10A is always in a state in which each lock spring (not shown) is engaged with each lower rail 11 by a spring urging force to lock the slide of each upper rail 12 in the front-rear direction.

Each lock mechanism 10A is connected to a loop handle 4A provided on the lower front portion of the seat cushion 3 and a boarding / alighting lever 4B provided on the right side portion of the seat cushion 3. As a result, each lock mechanism 10A is operated so that either the loop handle 4A or the boarding / alighting lever 4B is pulled up by the user, so that the lock mechanism 10A is engaged with each lower rail 11 against the spring-loaded force. It is designed to be removed from.

By the above operation, each upper rail 12 can freely slide in the front-rear direction with respect to each lower rail 11. Therefore, the position (seat position) of the seat 1 in the front-rear direction with respect to the floor F can be freely adjusted.

When the operation of the loop handle 4A or the boarding / alighting lever 4B is returned, the lock mechanism 10A is returned to the locked state of the slides of the upper rails 12 again at that position. As a result, the seat 1 can be fixed at the adjusted position where the position has been changed.

More specifically, each lock mechanism 10A is in a state in which when the boarding / alighting lever 4B is operated, the position in the front-rear direction in which the slide lock is released is memorized by the operation of the memory mechanism 20 (memory operation). It is designed to be removed from the engaged state with 11. As a result, each lock mechanism 10A adjusts the position of the seat 1 in the front-rear direction, and then moves the seat 1 again toward the position before the change. When the position before the change is reached, the memory mechanism 20 of the memory mechanism 20 By the operation, the slide of each upper rail 12 can be returned to the locked state by itself.

The slide rail 10 and the memory mechanism 20 have substantially the same configuration as the known configuration disclosed in documents such as JP-A-2019-137126. Therefore, detailed description of these specific configurations will be omitted.

The memory mechanism 20 described above is assembled on the slide rail 10 on the left side. Specifically, the memory mechanism 20 includes a memory rail 21 assembled on the bottom plate portion of the lower rail 11, a memory piece 22 that stores the position of the upper rail 12 before the change by mechanical engagement with the memory rail 21, and a memory piece 22. Has.

The memory rail 21 has a substantially uniform cross-sectional shape in the front-rear direction and has a long rail shape, and is set in a superposed manner on the bottom plate portion of the lower rail 11. The memory piece 22 is inserted into the rail of the memory rail 21 from the opening end on either side in the longitudinal direction and is assembled so as to be slidable only in the front-rear direction. The memory piece 22 is always engaged with the memory rail 21 by a spring-forced force, so that the slide in the front-rear direction with respect to the memory rail 21 is locked.

Even if the boarding / alighting lever 4B is operated, the memory piece 22 is held without being disengaged from the engaged state with the memory rail 21. Due to the above engagement, even if the seat position is changed by operating the boarding / alighting lever 4B, the memory piece 22 is left at the engagement position with the memory rail 21 without following the movement, and before the seat position is changed. It functions as a memory of the position.

The memory piece 22 is returned from the position where the seat position has been changed to the position before the change, so that a trigger member (not shown) of the memory mechanism 20 which moves together with the upper rail 12 is brought into contact with the memory piece 22. As a result, the memory piece 22 cancels the released state of each lock mechanism 10A by using the action of pressing and rotating the trigger member as a trigger, and locks each lock mechanism 10A at that position.

On the other hand, the memory piece 22 is removed from the engaged state with the memory rail 21 by operating the loop handle 4A. Then, the memory piece 22 moves in the front-rear direction on the memory rail 21 in a form of being guided by the upper rail 12 due to the movement of the upper rail 12 due to the change of the seat position. Then, when the operation of the loop handle 4A is released, the memory piece 22 is returned to the state of being engaged with the memory rail 21 again at that position.

As a result, the memory piece 22 is switched so that the changed position of the seat position is set as the new storage position. Therefore, the next time the boarding / alighting lever 4B is operated, the seat position can be easily returned to the position before the change by using the position of the moved memory piece 22 as a new storage position.

As shown in FIGS. 1 and 2, the seat 1 has a configuration in which a seat cushion 3 is provided so as to straddle the pair of left and right slide rails 10. Specifically, the seat cushion 3 is connected to the pair of left and right slide rails 10 via a pair of front and rear lifter links 5A and 5B that form the seat lifter 5, respectively. Specifically, the seat cushion 3 is connected via the pair of front and rear lifter links 5A and 5B, so that the left and right side frames 3A are inside the pair of left and right slide rails 10 in the vehicle width direction, respectively. It is said that it is offset to the left side.

The lifter links 5A and 5B constituting the seat lifter 5 are moved forward according to the operation movement amount by the operation of raising the lifter lever 5C provided on the right side portion (outer side portion in the vehicle width direction) of the seat cushion 3. It rotates in a shape that is raised around it. As a result, the lifter links 5A and 5B are adjusted so as to raise the height of the seat cushion 3 with respect to the floor F. Further, each of the lifter links 5A and 5B is rotated so as to be tilted backward according to the operation movement amount by the operation of lowering the lifter lever 5C. As a result, the lifter links 5A and 5B are adjusted so as to lower the height of the seat cushion 3 with respect to the floor F.

The right side of the seat cushion 3 is covered with a resin seat side shield (not shown). Further, the left side portion of the seat cushion 3 is simply covered with a planar carpet (not shown). Specifically, the carpet (not shown) is provided in a suspended shape with its upper edge sewn to the left side of the seat cushion 3. The reason why the left side portion of the seat cushion 3 is simply covered as described above is that a center console (not shown) is provided on the left side of the seat cushion 3 so that it is difficult to see from the outside.

As shown in FIGS. 1 and 3, the memory mechanism 20 is assembled on the base member 23 assembled on the upper rail 12 of the slide rail 10 on the left side. An operating member 30 is connected to the front portion of the base member 23. The operating member 30 is operated so as to be pulled backward via the operating cable 32 by operating the boarding / alighting lever 4B (see FIG. 2), unlocks the lock mechanism 10A of each slide rail 10, and stores the memory mechanism 20 in memory.
