Abstract
Description
[Technical Field]
[0001] The present invention relates to an operating strap, and more particularly to a band-shaped operating strap that is pulled out to the outside of a seat through a slit formed in the surface of the seat. [Background technology]
[0002] Patent Document 1 discloses an operating strap for a vehicle seat. This operating strap has a pull-out portion that is pulled out through a slit in the seat body and a ring-shaped grip portion formed at the end of the pull-out portion. The operating strap also has an intrusion prevention portion that prevents the grip portion from getting into the slit.
[0003] The intrusion prevention part is formed by folding back the end of the seam that is wound around the grip part into a ring shape and sewn together so that it overhangs the inside of the ring shape of the grip part. As a result, the intrusion prevention part is formed as a thick part that partially increases the thickness of the base of the grip part, and functions to restrict intrusion into the slit by hitting the periphery of the slit.

[0004] [Patent Document 1] Patent Publication No. 2021-17068 Summary of the Invention [Problem to be solved by the invention]
[0005] The configuration described in Patent Document 1 leaves room for improvement, as the anti-entrapment portion extends into the annular interior of the grip portion, narrowing the annular interior. Therefore, the present invention provides an operating strap that can prevent the grip portion from entering the slit with a rational configuration. [Means for solving the problem]
[0006] The control strap of the present invention solves the above problems by the following means: That is, a first aspect of the present invention is a band-shaped control strap that is pulled out to the outside of the seat from a slit formed in the surface of the seat, and includes: a pull-out portion that is pulled out from the slit; a grip portion that extends in a folded manner from the end of the pull-out portion and is sewn to close the pull-out portion into a circular shape; an extension portion that forms a seam at the end of the circularly sewn grip portion and extends in the opposite direction from the grip portion so as to overlap with the pull-out portion in the pull-out direction; and a separation shape maintaining portion that maintains at least a portion of the extension portion in a shape that is separated from the pull-out portion in the thickness direction.
[0007] According to the first aspect of the present invention, the extension portion, which is maintained in a shape spaced apart from the pull-out portion in the thickness direction, can prevent the grip portion from entering the slit by abutting the extension portion against the sheet surface. In this way, a rational configuration that utilizes an ingenious winding shape of the band-shaped operating strap can prevent the grip portion from entering the slit.
[0008] The second invention of the present invention is an operating strap according to the first invention, wherein the spaced shape maintaining portion is composed of a co-sewn portion that folds over and is co-sewn with the sewn portion that sews the grip portion into a ring shape, thereby maintaining the extended portion in a shape that expands into a ring shape in the thickness direction from the pull-out portion.
[0009] According to the second aspect of the present invention, the separation shape retention portion can be rationalized. Also, since the extension portion retains its shape by expanding annularly relative to the pull-out portion, the extension portion can more appropriately prevent the grip portion from entering the slit.
[0010] The third invention of the present invention is an operating strap in which, in the second invention described above, the extended end of the extension portion is sandwiched between the overlapping portions sewn together in a circular shape to the gripping portion and sewn together by the spaced shape retaining portion.
[0011] According to the third aspect of the present invention, the extending portion can be configured to have a good appearance without exposing the terminal to the outside.
[0012] The fourth invention of the present invention is an operating strap in any one of the first to third inventions above, wherein the extension portion is held by the spaced shape retaining portion, thereby preventing the gripping portion from collapsing due to bending of the pull-out portion by hitting the surface of the seat.
[0013] According to the fourth aspect of the present invention, the extension portion can appropriately prevent both the grip portion from entering the slit and the grip portion from collapsing due to bending of the drawn-out portion.
[0014] The fifth invention of the present invention is an operating strap according to the fourth invention, wherein the slit is formed so as to open upward on the upper surface of the seat back, and the operating strap is an operating member that switches a foldable headrest connected to the seat back to a state in which it can be tilted forward on the seat by pulling the gripping portion, and the extension portion prevents the gripping portion from falling forward by hitting the seat surface, but allows the gripping portion to fall backward without hitting the seat surface.
[0015] According to the fifth aspect of the present invention, by preventing the grip portion from tilting forward, the direction in which the grip portion tilts can always be directed toward the rear of the seat back. This makes it easier for the user to grasp and pull the grip portion from a position behind the seat back. Furthermore, if the seat back is designed to be tiltable forward, the grip portion can be appropriately prevented from being pinched between the seat back and the seat cushion when the seat back is tilted forward.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018] First Embodiment (Outline of the operation strap 1) First, the configuration of an operating strap 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 7. In the following description, when directions such as front, back, up, down, left, and right are indicated, they refer to the directions shown in each drawing. In the following description, when a specific reference drawing is not indicated or when there is no reference symbol corresponding to a reference drawing, any of Figures 1 to 7 will be referenced as appropriate.
[0019] As shown in Fig. 1, the operating strap 1 according to this embodiment is configured as a band-shaped operating member provided on the upper part of the seat back SB of the rear seat of an automobile. Specifically, the operating strap 1 is pulled out toward the top of the seat from a horizontally elongated slit SL, which is an upward opening formed on the upper surface of the seat back SB. The periphery of the slit SL is configured to be surrounded by a resin bezel BZ.
[0020] The operating strap 1 is made of a strip-shaped member woven from a high-strength continuous fiber such as polyester or nylon into a single, long strip with a constant width. Specifically, the operating strap 1 is configured to be wound into a loop with a looped grip portion 4 and a looped extension portion 5 by folding back the single strip of material in several places and sewing it into a closed loop.
[0021] 2, the operating strap 1 has a belt-shaped connection portion 2 that is connected to an operating cable (not shown) inside the seat back SB. The operating strap 1 also has a belt-shaped pull-out portion 3 that extends flush upward from the connection portion 2 and is pulled out to the outside of the seat through a slit SL. The operating strap 1 also has a grip portion 4 that extends flush upward from the end of the pull-out portion 3, and then folds back downward and forward in the figure, and is sewn into a ring shape by a stitching portion 6.
[0022] The operating strap 1 also has an extension 5 that forms a seam at the end of the circularly sewn grip portion 4. The extension 5 extends downward from the sewn portion 6 in the opposite direction to the grip portion 4, as shown in the figure, and is configured to overlap with the pull-out portion 3 in the pull-out direction.
[0023] The extension portion 5 extends downward as shown in the figure, then is folded back upward as shown in the figure, and the end at that point is sandwiched between the overlapping portions 4A, 4B of the grip portion 4 that are sewn together in a circular shape, and is sewn together with these in the thickness direction at the sewing portion 6. The sewing portion 6 is configured to sew together the overlapping portions 4A, 4B of the grip portion 4 and the end of the extension portion 5 that is sandwiched between them using an outstitch sewing method in which the sewing thread is visible from the front and back sides as shown in the figure.
[0024] As a result, the extension portion 5 is sewn onto the front surface of the drawn-out portion 3 to form a ring-shaped configuration aligned with the grip portion 4 in the vertical direction in the figure. In its free state, the extension portion 5 is configured to exert a restoring force that causes it to bulge forward from the drawn-out portion 3 in the figure, with the sewn portion 6 forming the closing portion of the ring-shaped configuration and the front surface of the drawn-out portion 3 facing rearward in the figure as fulcrums. Due to this bulge, the extension portion 5 forms a thick-diameter portion between itself and the drawn-out portion 3 that is wider in front-to-back than the slit SL.
[0025] Furthermore, the terminal of the extension portion 5 is sewn in a state where it is sandwiched between the overlapping portions 4A and 4B of the grip portion 4, so that the terminal is not exposed to the outside and is finished in a good-looking state. In this way, the operating strap 1 is configured such that the stitching portion 6 that closes the terminal of the extension portion 5 in a ring shape serves as the separated shape maintaining portion H1 that maintains the extension portion 5 in a ring shape expanding forward in the thickness direction from the pull-out portion 3 as shown in the figure.
[0026] (Operation strap 1 assembly procedure) The operating strap 1 having the above-described configuration is set in a state in which it is passed through the slit SL of the seat back SB from the inside of the seat (lower in the figure) to the outside of the seat (upper in the figure) by the following procedure: First, an operating cable (not shown) is connected to the connection part 2 of the operating strap 1.
[0027] Next, as shown in Fig. 3, the gripping portion 4 of the operating strap 1 is passed through the slit SL from the inside of the seat (bottom in the figure) to the outside of the seat (top in the figure). Specifically, with the width direction of the operating strap 1 facing the lateral direction of the slit SL, the operating strap 1 is passed through the slit SL from the inside of the seat (bottom in the figure) while squeezing the annular shape of the gripping portion 4 from the upper end side of the gripping portion 4.
[0028] As a result, after the grip portion 4 passes through the slit SL, the extension portion 5 is forced to contract its annular shape against the restoring force and is passed through the slit SL together with the pull-out portion 3. Then, by passing the operating strap 1 through the slit SL until the extension portion 5 completely passes through the slit SL to the outside of the seat (upward in the figure), the operating strap 1 is pulled out to its initial position before the operation of pulling the operating cable (not shown). As a result, the extension portion 5 is returned to its annular shape that bulges forward in the figure from the pull-out portion 3 due to its restoring force.
[0029] (Operation procedure for operation strap 1) 1, when the user grasps the grip portion 4 of the operating strap 1 assembled as described above, pulled out from the slit SL of the seat back SB, and pulls it upward on the seat, the operating cable (not shown) connected inside the seat back SB is pulled. This releases a locking mechanism (not shown) connected to the operating cable (not shown), and the foldable headrest HR attached to the top of the seat back SB is unlocked from its locked state in the use position. This unlocking switches the headrest HR to a state in which it can be folded forward relative to the seat back SB.
[0030] Specifically, the user grasps the grip portion 4 of the operating strap 1 with his / her hand and pulls it upward on the seat from a position where the user is standing behind the seat back SB with the vehicle's back door open. In this case, the operating strap 1 is always arranged so that the grip portion 4 is tilted from the top surface of the seat back SB toward the rear of the seat when the seat back SB is in the upright position where it is used as a backrest, as shown in Fig. 4 .
[0031] Specifically, as shown in Fig. 2, when the pull-out portion 3 of the operating strap 1 attempts to tilt forward on the seat with its base end threaded through the slit SL as a fulcrum, the lower edge of the extension portion 5, which is aligned on the front side of the pull-out portion 3 in the figure, strikes the upper surface of the bezel BZ or seat back SB, which forms the seat surface, preventing the operating strap 1 from tilting forward. Conversely, when the pull-out portion 3 of the operating strap 1 attempts to tilt backward on the seat with its base end threaded through the slit SL as a fulcrum, the extension portion 5 does not strike the upper surface of the bezel BZ or seat back SB, as shown in Fig. 4, allowing the operating strap 1 to tilt backward.
[0032] Therefore, the grip portion 4 of the operating strap 1 can always be placed in a state in which it is tilted from the top surface of the seat back SB toward the rear of the seat, and the user can easily grasp and pull the grip portion 4 from a position behind the seat back SB. Also, as shown in Figure 5, even if a force is applied to pull the pull-out portion 3 into the slit SL, the lower edge of the extension portion 5 of the operating strap 1 will hit the bezel BZ or the top surface of the seat back SB, which is the surface of the seat, and will therefore be prevented from entering the slit SL.
[0033] More specifically, the operating strap 1 is configured to apply a strong retraction restricting force to prevent the grip portion 4 from being drawn into the slit SL even when a strong retraction force is applied such that the pull-out portion 3 is drawn into the slit SL with further deformation of the extension portion 5 after the lower edge of the extension portion 5 abuts against the upper surface of the bezel BZ or the seat back SB. Specifically, as the pull-out portion 3 is drawn into the slit SL up to a position near the stitching portion 6, the starting point of deformation of the extension portion 5 is brought closer to the stitching portion 6.
[0034] Accordingly, the resistance to bending of the extension portion 5 gradually increases, and the force preventing it from entering the slit SL also gradually increases. Furthermore, as shown in FIG. 6, when the pull-out portion 3 is pulled into the slit SL up to a position near the sewn portion 6, the extension portion 5 comes into contact with the periphery (bezel BZ) of the slit SL and bends upward with the sewn portion 6 as a fulcrum. As a result, the extension portion 5 overlaps the three band portions sewn together at the sewn portion 6, forming a five-layer overlapping shape that is wider than the front-to-back width of the slit SL. Therefore, the grip portion 4 is strongly restricted from being pulled into the slit SL.
[0035] As described above with reference to Fig. 2, the operating strap 1 is prevented from falling forward by the gripping portion 4 hitting the extension portion 5, and therefore does not hang down below the seat back SB even when the seat back SB is folded forward, as shown in Fig. 7. Therefore, when the seat back SB is folded forward so as to overlap the upper surface of a seat cushion (not shown), the operating strap 1 can be appropriately prevented from being pinched between the seat back SB and the seat cushion.
[0036] As a result, it is possible to prevent the formation of indentations on both the seat back SB and the seat cushion due to pinching of the operating strap 1. It is also possible to prevent damage due to pinching of the operating strap 1 and erroneous operation due to unintentional catching.
[0037] To summarize the above, the operation strap 1 according to this embodiment has the following configuration: Note that the reference numerals in parentheses below correspond to the respective components shown in the above embodiment.
[0038] That is, the operating strap (1) is a strip-shaped operating strap (1) that is pulled out to the outside of the seat through a slit (SL) formed in the surface of the seat, and has a pull-out portion (3) that is pulled out from the slit (SL), a grip portion (4) that extends in a folded manner from the pulled-out end of the pull-out portion (3) and is sewn to close in a circular shape, an extension portion (5) that forms a seam at the circularly sewn end of the grip portion (4) and extends in the opposite direction to the grip portion (4) so that its arrangement in the pull-out direction overlaps with that of the pull-out portion (3), and a separation shape maintaining portion (H1) that maintains at least a portion of the extension portion (5) in a shape that is separated from the pull-out portion (3) in the thickness direction.
[0039] According to the above configuration, the extension portion (5), which is maintained in a shape spaced apart from the pull-out portion (3) in the thickness direction, can restrict the grip portion (4) from entering the slit (SL) by the extension portion (5) hitting the sheet surface. In this way, a rational configuration that utilizes an ingenious winding shape of the band-shaped operating strap (1) can prevent the grip portion (4) from entering the slit (SL).
[0040] In addition, the separation shape maintaining portion (H1) is made up of a stitched portion in which the extended end of the extension portion (5) is folded over and stitched together with the stitched portion (6) that stitches the grip portion (4) into a ring shape, thereby maintaining the extension portion (5) in a shape that expands into a ring shape in the thickness direction from the pull-out portion (3).
[0041] According to the above configuration, the separation shape maintaining portion (H1) can be rationalized. In addition, since the extension portion (5) maintains its shape by expanding annularly relative to the pull-out portion (3), the extension portion (5) can more appropriately prevent the grip portion (4) from entering the slit (SL).
[0042] In addition, the extending end of the extension portion (5) is sandwiched between the overlapping portions (4A, 4B) of the grip portion (4) that are sewn together into a ring shape, and is sewn together by the spaced shape maintaining portion (H1). According to the above configuration, the extending portion (5) can be configured to have a good appearance with its end not exposed to the outside.
[0043] Furthermore, the extension (5) is held by the spaced shape maintaining portion (H1), and prevents the gripping portion (4) from collapsing due to the bending of the pull-out portion (3) by hitting the sheet surface. According to the above configuration, the extension (5) can appropriately prevent both the gripping portion (4) from entering the slit (SL) and the gripping portion (4) from collapsing due to the bending of the pull-out portion (3).
[0044] In addition, a slit (SL) is formed on the upper surface of the seat back (SB) so as to open upward. The operating strap (1) is an operating member that switches the headrest (HR) connected to the seat back (SB) to a state in which it can be tilted forward of the seat by pulling the gripping portion (4). The extension portion (5) prevents the gripping portion (4) from colliding with the seat surface when it is tilted forward, but allows the gripping portion (4) to collapse backward without colliding with the seat surface.
[0045] According to the above configuration, the forward tilt of the grip portion (4) is prevented, so that the tilt direction of the grip portion (4) can always be directed toward the rear of the seat back (SB). Therefore, it is easier for the user to grasp and pull the grip portion (4) from a position behind the seat back (SB). Furthermore, if the seat back (SB) is designed to be able to tilt forward, the grip portion (4) can be appropriately prevented from being pinched between the seat back (SB) and the seat cushion when the seat back (SB) tilts forward.
[0046] Second Embodiment Next, the configuration of an operating strap 1 according to a second embodiment of the present invention will be described with reference to Fig. 8. In the operating strap 1 according to this embodiment, the extension portion 52 forming the seam allowance at the end of the circularly sewn grip portion 4 is not folded back upward as shown in the figure, but is bent back forward from the pull-out portion 3 as shown in the figure to form a U-shape in side view, and the end at that point is sewn to the pull-out portion 3 by another stitching portion 7. The another stitching portion 7 is configured to sew the end of the extension portion 52 to the pull-out portion 3 at a position away from the stitching portion 6 that sews the grip portion 4 into a circular shape and to the lower side as shown in the figure.
[0047] The distance between the seam 6 and another seam 7 is shorter than the circumferential length of the extension 52 that is bent forward in a U-shape in side view between them. Therefore, the extension 52 is maintained in a shape that bulges annularly forward from the pull-out portion 3 in the figure between the seam 6 and another seam 7 of the pull-out portion 3, and this extension 52 appropriately prevents the grip portion 4 from entering the slit SL. Furthermore, due to this bulge, the extension 52 can prevent the pull-out portion 3 from colliding with the upper surface of the bezel BZ or the seat back SB when it tries to tilt forward on the base end that is passed through the slit SL as a fulcrum.
[0048] In this way, the operating strap 1 is configured such that the separate stitching portion 7 forms a spaced shape retaining portion H2 that retains the extending portion 52 in a circular shape expanding forward in the thickness direction from the pull-out portion 3. The separate stitching portion 7, like the stitching portion 6, is configured to sew the end of the extending portion 52 to the pull-out portion 3 using an outstitch stitch so that the stitching thread is visible from the front and back sides in the figure. As a result of the stitching, the extending portion 52 extends downward from the stitching portion 6 in the figure and extends upward from the separate stitching portion 7 in the figure, thereby properly retaining the shape pushed forward in the figure.
[0049] The configuration other than the above is substantially the same as that of the operation strap 1 shown in the first embodiment. Therefore, the configuration other than the above is denoted by the same reference numerals as those of the operation strap 1 shown in the first embodiment, and detailed description thereof will be omitted.
[0050] Third Embodiment Next, the configuration of an operating strap 1 according to a third embodiment of the present invention will be described with reference to Fig. 9. In the operating strap 1 according to this embodiment, an extension portion 53 forming a seam allowance at the end of the circularly sewn grip portion 4 extends downward as shown in the figure, then extends in a manner that is folded back upward toward the front as shown, and the end of the extension portion is overlapped on the front surface of the overlap portion 4A at the front side as shown in the figure that is circularly sewn of the grip portion 4, and both overlap portions 4A, 4B are sewn together in the thickness direction at a sewing portion 6. The sewing portion 6 is configured to sew together the end of the extension portion 53 and both overlap portions 4A, 4B of the grip portion 4 using an outstitch so that the sewing thread is visible from the front and back sides as shown.
[0051] As a result of the above stitching, the extension portion 53 is sewn onto the front surface of the drawer portion 3 in a ring-shaped configuration aligned vertically with the grip portion 4. In its free state, the extension portion 53 is configured to exert a restoring force such that it bulges forward from the drawer portion 3, with the stitching 6 forming the closing portion of the ring-shaped configuration and the front surface of the drawer portion 3 facing rearward in the illustration as fulcrums.
[0052] Due to the bulge, the extension 53 forms a thick-diameter portion between the extension 53 and the drawer 3 that is wider in the front-to-rear direction than the slit SL, thereby appropriately preventing the grip 4 from entering the slit SL. Furthermore, due to the bulge, the extension 53 can prevent the drawer 3 from colliding with the upper surface of the bezel BZ or the seat back SB when the extension 53 tries to tilt the seat forward with the base end of the drawer 3 that is passed through the slit SL as a fulcrum.
[0053] In this way, the operating strap 1 is configured such that the stitching 6 that closes the end of the extended portion 53 into a ring shape serves as a spaced shape retaining portion H3 that holds the extended portion 53 in a ring shape expanded forward in the thickness direction from the pull-out portion 3. Note that the configuration other than the above is substantially the same as the operating strap 1 shown in the first embodiment. Therefore, the configuration other than the above is denoted by the same reference numerals as the operating strap 1 shown in the first embodiment, and detailed description thereof will be omitted.
[0054] Fourth Embodiment Next, the configuration of an operating strap 1 according to a fourth embodiment of the present invention will be described with reference to Fig. 10. In the operating strap 1 according to this embodiment, an extension 54 forming a seam allowance at the end of the circularly sewn gripping portion 4 is configured to be bent obliquely downward in the front direction in the drawing in a free state by a bending portion 8 formed at the base end portion near the sewn portion 6.
[0055] By this bending, in a free state, the extension portion 54 is configured so that its extended end is held in a shape that protrudes obliquely downward and forward in the drawing relative to the drawer 3. This protrusion forms a thick-diameter portion between the extension portion 54 and the drawer 3 that is wider in the front-to-back direction than the slit SL, thereby appropriately preventing the grip portion 4 from entering the slit SL. Furthermore, this protrusion prevents the extension portion 54 from colliding with the bezel BZ or the upper surface of the seat back SB when the drawer 3 tries to tilt forward with its base end inserted into the slit SL as a fulcrum.
[0056] In this way, the operating strap 1 is configured such that the shaping portion 8, which shaping the extension portion 54 into a folded state, is formed as a spaced shape retaining portion H4, which holds the extension portion 54 in a shape that protrudes forward in the thickness direction from the pull-out portion 3. Note that the configuration other than the above is substantially the same as the operating strap 1 shown in the first embodiment. Therefore, the configuration other than the above is denoted by the same reference numerals as the operating strap 1 shown in the first embodiment, and detailed description thereof will be omitted.
