The 1st slider connection body 70A and the 2nd slider connection body 70B are mutually comprised similarly, and are arrange|positioned as a pair in the X direction. Moreover, 61 A of 1st fastener stringers and the 2nd fastener stringer 61B are opposed to the Y direction which is a width direction, and make the X direction which is a direction orthogonal to a width direction a longitudinal direction. And the 1st fastener stringer 61A and the 2nd fastener stringer 61B are integrated by the 1st slider connection body 70A and the 2nd slider connection body 70B, and can open and close in the X direction. In addition, the slide fastener 60 in this embodiment is equipped with the 1st fastener stringer 61A, the 2nd fastener stringer 61B, 70 A of 1st slider coupling bodies, and the 2nd slider coupling body 70B as components, and a pair of slide fastener stringers The unit that the tooth chain belt and a pair of sliders are integrated is called a zipper unit. And, about the fastener unit, it will be described in the manufacturing method of the movement guide device 10 to be discussed later.

The first fastener stringer 61A includes: a fastener tape 62 disposed so as to cover the opening 211 of the guide groove 21; and a fastener element 65 attached to the fastener tape 62, and the first slider coupling body 70A and The second slider coupling body 70B is slidably coupled to the fastener element 65 .

The fastener tape 62 has a tape portion 621 along the X direction and a swollen portion 622 formed by a core thread or the like on the Y-direction outer side edge portion of the tape portion 621 . The belt portion 621 is disposed so as to be inserted into the gap between the side edge portion 411 of the first side cover 40A and the upper panel portion 25 , and the enlarged portion 622 is configured so as to be able to contact the side edge portion 411 during the closing movement of the fastener tape 62 . The mode is configured in the groove 45 .

The fastener tape 62 can open and close in the Y direction, and when the enlarged portion 622 abuts against the side edge portion 411 of the cover body piece 41, the fastener tape 62 is attached to the first side cover 40A without falling off. The one side cover 40A is engaged.

In addition, since the 2nd fastener stringer 61B is comprised similarly to 61 A of 1st fastener stringer, and is arrange|positioned in a pair in reverse left and right, the same code|symbol is attached|subjected suitably in a figure, and detailed description is abbreviate|omitted.

The slot shielding unit 15 is formed by the aforementioned first side cover 40A, second side cover 40B, and slide fastener 60 .

As shown in FIG. 6 , the dimension G of the gap between the top panel portion 25 and the side edge portion 411 is larger than the thickness dimension of the tape portion 621 of the fastener tape 62 . The protruding dimension L1 of the rib 43 (dimension from the lower surface of the cover body piece 41 to the front end surface of the rib 43 ) is equal to the groove depth dimension of the groove 45 . Therefore, the difference between the dimension from the lower surface of the cover body piece portion 41 to the lower surface of the side edge portion 411 and the protrusion dimension L1 of the rib 43 is the dimension G. The width dimension W1 of the groove 45 in the Y direction is a dimension obtained by adding the width dimension W2 of the enlarged portion 622 in the Y direction to the width dimension W3 of the enlarged portion 622 that moves to the maximum in the Y direction. The dimension twice the dimension W3 corresponds to the width dimension W of the maximum opening width of the slide fastener 60 shown in FIG. 5 .

In addition, since the slide fastener 60 should just be a slide fastener which can be opened and closed by the slider coupling body 70A, 70B, it is not limited to the form of the fastener element 65 mentioned later, It is possible to use the slide fastener element which can repeat engagement and disengagement of fastener elements. of various forms. For example, a rail slide fastener in which fastener elements are releasably engaged in concave and convex can be used.

[Operation of the first embodiment]

Hereinafter, the operation of the movement guidance device 10 of the first embodiment will be described.

First, the upper rail 30 moves in the X direction relative to the lower rail 20 as the car seat 1 moves forward and backward. At this time, the first slider coupling body 70A on the front side in the moving direction of the upper rail 30 disengages and separates the fastener elements 65 engaged as shown in FIG. Direction outside open movement. Thereby, as shown in FIG. 5, the part of the slide fastener 60 on the rear side with respect to 70 A of 1st slider coupling bodies will be in the open state opened. On the other hand, the second slider coupling body 70B on the rear side in the moving direction of the upper rail 30 engages the fastener elements 65 separated in the left-right direction as shown in FIG. The portion on the rear side of the two slider coupling body 70B is in a closed state.

In addition, when the movement of the car seat 1 in the front-rear direction is in the opposite direction to the aforementioned moving direction, the second slider link 70B is located on the front side in the moving direction of the upper rail 30 , and the first slider link 70A is located on the front side of the upper rail 30 . On the rear side, roughly the same action as the aforementioned action is performed.

In this way, when the upper rail 30 moves in the X direction, the slide fastener 60 opens only the portion of the upper rail 30 located in the opening 211 of the guide groove 21, and makes the other portions in the closed state. Therefore, the state in which the opening portion 211 is shielded by the slide fastener 60 is maintained. Therefore, it is possible to prevent small objects or the like from entering the guide groove 21 , or foreign matter such as soil to accumulate in the guide groove 21 to prevent the movement of the upper rail 30 . In addition, even if the fastener tape 62 is opened and closed, it hardly bends. Therefore, the material of the fastener tape 62 can be a resin material that is harder than a cloth material, and can be made to be hard to bend even if the fastener tape 62 is pressed from the outside. Fall into the structure of the guide groove 21. For example, as the fastener tape 62, a synthetic resin alone or a composite of synthetic resin and cloth can be used.

[Effect of the first embodiment]

(1) Utilize a piece of cover main body part 41 to constitute the position (groove 45, side edge part 411) for engaging with zipper tape 62, thus, form the overall shape and form the trunk of substantially U-shaped or C-shaped shape. Compared with the case of the first side cover 40A (second side cover 40B), the thickness dimension of the trunk portion can be reduced and slimmed down.

In addition, after the fixed piece portion 42 of the first side cover 40A (second side cover 40B) is fixed to the lower rail 20, the rib 43 protruding from the lower surface of the cover main body piece portion 41 contacts and supports the lower rail 20. The cover body piece 41 can therefore suppress deflection when an external force is applied to the cover body piece 41 such as being stepped on. Therefore, an increase in the resistance against the opening and closing movement of the fastener tape 62 due to the cover body piece 41 being pressed against the fastener tape 62 can be suppressed, and the movement guide device 10 can be operated smoothly.

(2) When the fastener tape 62 moves to open and close according to the movement of the upper rail 30 , the enlarged portion 622 swings between the side edge portion 411 and the rib 43 in the groove 45 . Therefore, it is possible to eliminate deflection deformation caused by the fastener tape 62 being pressed against the first side cover 40A (second side cover 40B) due to the opening movement.

In addition, when the expanded portion 622 is in contact with the side edge portion 411 of the cover body piece portion 41, the fastener tape 62 is engaged with the first side cover 40A (second side cover 40B), so this can be prevented. The zipper tape 62 comes off.

(3) The rib 43 is continuous in the longitudinal direction of the cover main body piece portion 41. Therefore, the rib 43 can be made to abut against the lower rail 20 over the entire length direction of the cover main body piece portion 41. The cover main body piece 41 can be supported more reliably than the support protrusion which locally abuts on the lower rail 20 in the longitudinal direction.

[the second embodiment]

Next, a movement guidance device 10A according to a second embodiment of the present invention will be described.

As shown in FIG. 7 , the movement guide device 10A has substantially the same configuration as the movement guide device 10A of the first embodiment, but includes a first fastener stringer 66A, a second fastener stringer 66B, a first side cover 46A, and a first fastener stringer. The point that the second side cover 46B is used instead of the first fastener stringer 61A, the second fastener stringer 61B, the first side cover 40A, and the second side cover 40B is different.

The first fastener stringer 66A has the aforementioned fastener elements 65 and the fastener tape 62 , but the Y-direction outer side edge of the tape portion 621 is bent upward, and the enlarged portion 622 is arranged at the tip end thereof.

The first side cover 46A has the cover body piece 41 and the fixing piece 42 , but the top end 431A of the rib 43 is formed to extend toward the side edge 411 . In addition, in the first side cover 46A, in addition to the rib 43 , an additional rib 43A is formed between the rib 43 and the fixed piece portion 42 to contact the upper piece portion 25 . Here, the opening size between the front end portion 431A of the rib 43 and the side edge portion 411 (here, the opening size in the Y direction) is smaller than the diameter size of the enlarged portion 622 . The front-end|tip part 431A of the rib 43 is located below the fastener tape 62 of the 1st fastener stringer 66A.

In addition, the 2nd fastener stringer 66B and the 2nd side cover 46B are comprised similarly to the 1st fastener stringer 66A and 1st side cover 46A, and are arrange|positioned right and left reversely.

In this movement guide device 10A, as the fastener tape 62 moves to open and close, the enlarged portion 622 slides into the groove 45 and swings in the Y direction. According to this movement guide device 10A, the opening between the front end portion 431A of the rib 43 and the side edge portion 411 of the cover main body piece 41 is narrowed, so that the enlarged portion 622 serving as the fastener tape 62 does not dislodge from the first side cover. 46A (second side cover 46B) has a structure in which the groove 45 falls off. Therefore, the zipper 60, the first side cover 46A, and the second side cover 46B can be handled in a combined state, and the installation of the zipper 60 and the installation work of the first side cover 46A and the second side cover 46B to the lower rail 20 can be easily performed. .

[the third embodiment]

Hereinafter, a movement guidance device according to a third embodiment of the present invention will be described.

The movement guide device according to the third embodiment has substantially the same configuration as the movement guide device 10 according to the first embodiment, but as shown in FIG. The side edge portion 411 is formed so as to extend, and the side edge portion 411 is formed with an inclined surface 411A, and the enlarged portion 622 of the fastener tape 62 is eccentric to the lower side (the front end portion 431A side) with respect to the tape portion 621 . The inclined surface 411A is formed by the inner surface forming the groove 45 in the side edge portion 411 , and slopes from the top end portion 431A side of the rib 43 toward the base end portion 432 side as it goes toward the rib 43 side.

According to this movement guide device, the front end portion 431A of the rib 43 extends toward the side edge portion 411 , and even when the fastener tape 62 is bent to arrange the enlarged portion 622 in the groove 45 , the aforementioned inclined surface 411A can be used. This fastener tape 62 is guided in the direction which opens and closes and moves the fastener tape 62, and can open and close the slide fastener 60 smoothly. Here, the opening size between the front end portion 431A of the rib 43 and the side edge portion 411 (here, the opening size in the Z direction) is smaller than the diameter size of the enlarged portion 622 .

[the fourth embodiment]

Hereinafter, a movement guidance device according to a fourth embodiment of the present invention will be described.

The movement guide device of the fourth embodiment has substantially the same structure as the movement guide device 10 of the first embodiment. As shown in FIGS. The protrusion 43B is used instead of the rib 43 , and the fastener tape 62 has a plurality of long holes 623 formed in the tape portion 621 instead of the enlarged portion 622 . The plurality of support protrusions 43B are arranged along the longitudinal direction of the cover body piece 41 , and are arranged in the plurality of elongated holes 623 . The plurality of long holes 623 are along the Y direction which is the opening and closing movement direction of the fastener tape 62 .

According to this movement guide device, the fastener tape 62 can be opened and closed within the range where the support protrusion 43B does not contact the longitudinal end of the elongated hole 623. Therefore, it is possible to prevent the fastener tape 62 from being pressed against the first edge due to the open movement of the fastener tape 62. The deflection deformation caused by the side cover 40A (second side cover 40B).

In addition, when the support protrusion 43B comes into contact with the longitudinal end of the elongated hole 623, the fastener tape 62 is engaged with the first side cover 40A (second side cover 40B), thereby preventing the fastener tape 62 from falling off. .

Furthermore, since there is no need to form the groove 45 between the side edge portion 411 of the cover main body piece 41 and the support protrusion 43B, the Y-direction width dimension of the cover main body piece 41 can be reduced.

Hereinafter, an example of the manufacturing method (assembly method) of the movement guidance apparatus of the said 1st - 4th embodiment is demonstrated using the movement guidance apparatus 10 of 1st Embodiment. Before describing an example of the manufacturing method, as shown in FIGS. 11 to 13 , the attachment structure between the first slider coupling body 70A and the upper rail 30 will be described about the movement guide device 10 according to the first embodiment. In addition, since the 1st slider connection body 70A and the 2nd slider connection body 70B have the same structure as mentioned above, about the attachment structure between the 2nd slider connection body 70B and the upper rail 30, detailed description is abbreviate|omitted. Hereafter, 70 A of 1st slider coupling bodies and the upper rail 30 are demonstrated based on the state which attached 70 A of 1st slider coupling bodies to the upper rail 30 as a reference.
