JP 2005-125814 A

  However, in the above prior art, since the clip is held in a state of being pushed back in the direction of being pulled out of the mounting hole by the elastic force of the stabilizer, the clip is in a floating state with respect to the attached object. . The present invention was devised to solve the above problems, and the problem to be solved by the present invention is that the clip is attached in a state of being loosely packed in the direction of deepening the insertion into the attachment hole. There is to do.

  In order to solve the above problems, the clip of the present invention takes the following means.

  1st invention is a clip inserted and attached to an attachment hole, and it engages in the state where it was applied to the back side of the tip where the attachment hole was inserted, and was prevented from coming off. An engaging claw, a restricting portion applied to the front side surface of the mounting hole when the engaging claw is inserted to a position where the engaging claw is engaged with the mounting hole, And an interference portion that is inserted and elastically pressed against the back side surface of the mounting hole.

  According to the first aspect of the invention, the clip is inserted into the attachment hole until the position where the restricting portion hits the front side surface of the attachment hole. It will be in the state elastically pressed by the back side surface of the attachment hole. As a result, the clip is pressed in the direction of deepening the insertion into the mounting hole by the elastic force of the interference portion. Therefore, the clip can be attached in a state of being loosely packed in the direction of deepening the insertion with respect to the attachment hole.

  The second invention is the following configuration in the first invention described above. The interference part is formed on the back surface part applied to the back side surface of the mounting hole of the engaging claw, and is pressed against the peripheral edge of the tip into which the mounting hole is inserted at an oblique angle facing outward in the radial direction. It is formed as an inclined surface portion that is inclined as shown.

  According to the second aspect of the present invention, the clip can be brought into a state of being appropriately pressed against the back side surface of the mounting hole by only inserting the clip without causing the interference portion to be gripped. In addition, the interference portion can also be used to perform backlash in the radial direction with respect to the mounting hole of the clip.

  The third invention is the following configuration in the second invention described above. The interference part is formed in a shape in which the inclination toward the outer side in the radial direction is partly tighter than the surface part on the back side of the engaging claw in the end area in the radial direction on the surface part on the back side of the engaging claw. Yes.

  According to the third aspect of the invention, the surface portion on the back side of the engaging claw that is disengaged from the interference portion can be changed with respect to the back side surface of the mounting hole at an angle that can exert a strong retaining force with little inclination. it can. Therefore, it is possible to provide an interference portion that performs backlashing in the insertion direction of the clip without reducing the retaining force of the engaging claw.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

  First, the configuration of the clip 10A according to the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the clip 10 </ b> A of the present embodiment is applied to an assembly structure between constituent members of a support base 5 provided on both left and right sides of a vehicle seat 1. Here, the seat 1 is configured as a second seat in a so-called minivan type automobile having three rows of seats, more specifically as a second seat behind the driver seat. The seat 1 includes a seat back 2 that serves as a backrest for a seated person, a seat cushion 3 that serves as a seating portion, a headrest 4 that serves as a headrest, and a standing wall-like support that is erected on both left and right sides of the seat cushion 3. And a base 5. In the following description, “inside the vehicle” and “outside the vehicle” indicate “inside” and “outside” in the width direction of the vehicle, respectively.

  The seat back 2 described above is provided with its lower end connected to the rear end of the seat cushion 3. The seat cushion 3 is provided on the floor F of the vehicle so as to be slidable back and forth via a pair of left and right slide rails (not shown). The headrest 4 is mounted on the upper portion of the seat back 2. Each support base 5 is formed in a vertically long box shape, and the side portions on the inner side in the width direction are integrally connected to the left and right side portions of the seat cushion 3.

  As for each support stand 5 mentioned above, those upper surface parts are comprised as 5 A of armrests. In addition, each support base 5 has an outer surface portion that covers the lower area of the armrest 5A, the seat cushion 3 and the lower area of the support base 5 widely from outside in the front-rear direction, and is grounded on the floor F of the vehicle. It is formed in a shape extending in a substantially cylindrical shape to the lower side up to the vicinity position. Of these, the support base 5 provided on the side portion inside the vehicle has a front surface portion and an outer surface portion covered with a front shield 5B and a side shield 5C made of polypropylene resin, respectively. .

  The front shield 5B and the side shield 5C described above are each constituted by separate parts molded by injection, and as shown in FIGS. 2 to 3, a plurality of clips 10A, 10B formed between each other. And the attachment holes 21 and 22 are integrally attached by an insertion-type fitting structure A. Specifically, the plug-in fitting structure A includes clips 10A and 10B provided at three positions in the height direction along the vehicle inner edge of the front shield 5B, as shown in FIG. A vertically long, substantially rectangular shape formed so as to penetrate through three corresponding positions in the height direction along the flange-shaped attachment portion 20 formed by bending the front shield of the side shield 5C to the outside of the vehicle. The mounting holes 21 and 22 are shaped.

  Each of the above-described clips 10A and 10B is configured to be engaged with each of the mounting holes 21 and 22 by being inserted from the front side with respect to the corresponding mounting holes 21 and 22, respectively. In detail, each clip 10A, 10B will be in the state where the attachment direction with respect to each attachment hole 21 and 22 and the backlash in the opposite direction are each elastically pressed with respect to each attachment hole 21 and 22. So that it can be attached. More specifically, each of the clips 10A and 10B is elastically squeezed in a direction in which the insertion into each of the mounting holes 21 and 22 is deepened with respect to each of the mounting holes 21 and 22, respectively. It is configured to be attached in a state where the backlash is elastically pressed down.

  With such a configuration, the vehicle inner edge of the front shield 5B is in close contact with the front edge of the side shield 5C without leaving a gap in the front-rear direction and in a good-looking state. It is supposed to be attached. Hereinafter, the insertion type fitting structure A formed between the front shield 5B and the side shield 5C described above will be described in detail. The above-described clip 10A, 10B and the mounting structure with respect to each of the mounting holes 21, 22 have the same basic configuration. Therefore, in the following, the height of the front shield 5B will be representative. The attachment structure of the clip 10A provided at the substantially central portion in the vertical direction and the attachment hole 21 formed at the substantially central portion in the height direction of the side shield 5C corresponding thereto will be described in detail.

  As shown in FIGS. 5 to 6, the clip 10 </ b> A is integrally formed on the inner surface of the surface portion of the front shield 5 </ b> B that protrudes rearward from the vehicle inner edge. The clip 10A includes a main body portion 11 inserted from the front side into a corresponding mounting hole 21 formed in the side shield 5C, a restriction portion 12 formed at a root portion in the insertion direction of the main body portion 11, and An engaging claw 13 formed at an intermediate portion in the insertion direction, a guide portion 14 for guiding insertion into the mounting hole 21 of the main body portion 11, and an emergency hook portion formed at a distal end portion of the main body portion 11 in the insertion direction 15 and an interference portion 16 formed at the base portion of the engaging claw 13.

  The main body 11 is formed in a vertically oriented plate shape extending from a connecting plate 12B of the restricting portion 12 described later toward the rear side of the vehicle, which is the insertion direction into the mounting hole 21. The restricting portion 12 is formed in a shape that rises in a lateral U-shaped shape connecting both ends to the inner surface from the inner surface of the surface portion of the front shield 5B that protrudes rearward from the inner edge of the vehicle. From the connecting plate 12B that connects the U-shaped rising plates 12A of the restricting portion 12, the main body 11 described above is formed so as to extend toward the rear side of the vehicle flush with the connecting plate 12B. ing. As shown in FIG. 7, when the main body 11 is inserted into the attachment hole 21 of the side shield 5 </ b> C, the restricting portion 12 has both U-shaped rising plates 12 </ b> A on the front side surface 20 </ b> A around the attachment hole 21. It abuts and functions to regulate the movement of the main body 11 in the insertion direction.

  As shown in FIGS. 5 to 6, the engaging claw 13 is formed so as to protrude in a mountain shape in cross section from the inner side surface (side surface outside the vehicle) in the width direction at the intermediate portion in the insertion direction of the main body portion 11. It is configured. Specifically, the engaging claw 13 is formed in a shape in which a mountain shape that swells in the width direction from the main body portion 11 changes in the insertion direction of the main body portion 11. On both upper and lower side portions of the engaging claw 13 that swells in a mountain shape, slits 13 </ b> A are formed through the engaging claw 13 so as to be partially separated from the main body portion 11 along the side portions. . By these slits 13 </ b> A, the engaging claws 13 are easily bent in the width direction with respect to the main body portion 11.

  The engaging claw 13 is formed such that a slope 13B on the front side facing the rear side of the vehicle, which is the insertion direction, is formed as an inclined surface that relatively gently rises, and is opposite to the insertion direction. The back side slope portion 13C with the surface facing the front side is formed as an inclined surface that rises abruptly compared to the slope portion 13B. As shown in FIGS. 9 to 11, when the main body 11 is inserted into the mounting hole 21, the engaging claw 13 is brought into contact with the inner peripheral surface of the mounting hole 21 in the radial direction. It is inserted into the mounting hole 21 while being squeezed inside. Specifically, the engaging claw 13 is inserted in a state in which the main body 11 is supported from one side (the vehicle inner side) in the width direction with respect to the mounting hole 21 by a guide structure of the guide part 14 described later. As a result, the contact hole 21 is inserted into the mounting hole 21 while being pressed and narrowed by hitting the other peripheral edge (vehicle outer peripheral edge) of the mounting hole 21.

  And as shown in FIG. 7, the said engagement nail | claw 13 inserts the attachment hole 21 as shown in FIG. 7, when the said main-body part 11 is inserted to the position which the control part 12 mentioned above contact | abuts the surface side 20A around the attachment hole 21. It is inserted to a position where it passes through and is restored and deformed, and is returned to a shape projecting outward from the mounting hole 21 in the radial direction. By the insertion, the engaging claw 13 is placed in a state where the above-described slope 13C on the back side faces the front side surface 20B around the insertion hole 21 in the front-rear direction of the vehicle. As a result, the main body 11 is held in a state in which the movement in the pull-out direction with respect to the attachment hole 21 is restricted by the protruding shape of the engaging claw 13. Here, the slope portion 13C on the back side corresponds to the “back side surface portion” of the present invention.

  As described above, the engaging claw 13 described above is inserted into the mounting hole 21 so as to hit the mounting hole 21 and receive a pressing force inward in the radial direction. The slope portion 13C on the back side, which is in a state applied to the surrounding back side surface 20B, has a shape that rises abruptly. Therefore, the force for pulling out the engaging claw 13 from the inserted position acts more strongly than the force for inserting the engaging claw 13 into the mounting hole 21. Therefore, although the engagement claw 13 can be inserted into the attachment hole 21 with a relatively light force, the engagement claw 13 can be held in a state of being inserted into the attachment hole 21 with a relatively strong force. When the engaging claw 13 is inserted to the restriction position, the clip 10A is attached in a state where the engagement claw 13 and the restriction portion 12 sandwich the periphery of the attachment hole 21 from the front and back sides and are prevented from being detached. Become.

  As shown in FIGS. 5 to 6, the guide portion 14 is flush with the plate portion from a part in the width direction of the rear edge portion of the U-shaped both rising plates 12 </ b> A of the restriction portion 12 described above. The structure is formed so as to extend obliquely in a substantially triangular shape so as to be connected to the outer side surface (side surface on the inner side of the vehicle) of the main body 11 described above toward the rear side of the vehicle. Specifically, as shown in FIG. 5, the guide portion 14 is arranged on the vehicle rear side from the rear edge portion of the U-shaped rising plates 12 </ b> A of the restricting portion 12 to a position near the front end in the insertion direction of the main body portion 11. It is formed in a substantially triangular shape extending obliquely inward in the width direction (vehicle outer side).

  As for the said guide part 14, the outer peripheral surface which comprises the substantially triangular slope part forms the 1st inclined surface 14A, the 2nd inclined surface 14B, and the perpendicular surface 14C in order from the front end side of the insertion direction to the terminal end side. It has been configured. 14 A of 1st inclined surfaces are the outer sides of the area | region of the width direction of the area | region in which the emergency hook part 15 mentioned later in the front-end | tip part of the insertion direction of the main-body part 11 mentioned above was formed in the inner surface (side surface outside a vehicle) of the width direction. It is formed in a shape that rises obliquely from the side surface (side surface on the vehicle inner side) toward the vehicle front side.

  The second inclined surface 14B is formed in such a manner that it rises toward the front of the vehicle at a gentler angle than the first inclined surface 14A from the edge of the first inclined surface 14A that rises. The vertical surface 14 </ b> C is formed in a shape that extends straight from the leading edge of the above-described second inclined surface 14 </ b> B to the vehicle front side in a direction substantially parallel to the insertion direction of the main body 11. The vertical surface 14C is straight toward the restricting portion 12 from a position near the apex of the claw 13 of the engaging claw 13 formed on the inner side surface (side surface on the vehicle outer side) of the main body 11 and the width direction. It is formed in a shape extending to the front side of the vehicle.

  As shown in FIGS. 9 to 10, the first inclined surface 14 </ b> A is first inserted into the mounting hole 21 when the main body 11 described above is inserted into the mounting hole 21. 14 A of said 1st inclined surfaces are inserted in the attachment hole 21 by the shape which stands | starts up diagonally from the outer surface (side surface inside a vehicle) of the width direction of the main-body part 11, and a main-body part is applied to the inner peripheral surface. 11 is moved and guided (centered) so as to be sent inward in the width direction (outside of the vehicle) with movement in the insertion direction.

  And when the said main-body part 11 is further inserted in the attachment hole 21, the 2nd inclined surface 14B is inserted in the attachment hole 21 next. Similarly to the first inclined surface 14A, the second inclined surface 14B is inserted into the mounting hole 21 and applied to the inner peripheral surface of the second inclined surface 14B so as to move the main body 11 in the insertion direction. Along with this, movement guidance (centering) is performed so as to further feed the inside in the width direction (outside the vehicle). Since the second inclined surface 14B has a shape that rises more slowly than the first inclined surface 14A described above, the second inclined surface 14B is fed and moved in the width direction so that the insertion position of the main body portion 11 in the width direction is slightly finely adjusted. It is supposed to let you.

  And when the main-body part 11 is further inserted in the attachment hole 21, the vertical surface 14C is then inserted in the attachment hole 21, as shown in FIG. In that case, the above-mentioned engagement claw 13 in the position aligned with the vertical surface 14 </ b> C in the width direction is also inserted into the attachment hole 21. Here, the width between the vertical surface 14C and the inner side surface (side surface outside the vehicle) in the width direction of the main body 11 described above is slightly smaller than the width length of the mounting hole 21. By being inserted into the attachment hole 21 together with the portion 11, a slight gap in the width direction is generated inside the attachment hole 21.

  However, as shown in FIG. 7, the gap is inserted into the attachment hole 21 to a position where the movement of the main body portion 11 in the insertion direction is restricted by the restriction portion 12 described above. The interference part 16 formed at the base part of the engaging claw 13 inserted into the 21 interferes with the state where the interference part 16 is pressed against the peripheral edge part into which the mounting hole 21 is inserted, so that the gap is filled. . The configuration of the interference unit 16 will be described later.

  As shown in FIG. 5 to FIG. 6, the emergency hook 15 is formed by projecting in a mountain-shaped cross section from the distal end in the insertion direction of the main body 11 toward the inner side in the width direction (vehicle outer side). It is set as the structure. The emergency hook 15 is formed in a shape that swells in the width direction to the same position as the engagement claw 13 described above. The emergency hook 15 is formed with an inclined surface that faces the vehicle rear side, which is the insertion direction, but the surface facing the opposite side of the insertion direction is the width direction of the main body 11. It is configured as a regulating surface 15A that rises at an angle close to the vertical from the inner side surface (side surface outside the vehicle).

  As shown in FIGS. 9 to 11, the emergency hook 15 is inserted in advance of the attachment hole 21 when the main body 11 is inserted into the attachment hole 21. As shown in FIG. 7, the emergency hook 15 is attached in a state where the clip 10A is held between the engaging claw 13 and the restricting portion 12 by sandwiching the periphery of the mounting hole 21 from both front and back sides. In this state, the engaging claw 13 that extends through the mounting hole 21 through the insertion direction and is restored and deformed in the area where the mounting hole 21 is inserted is further spaced apart at a position on the rear side of the vehicle. It is supposed to be in a state.

  The emergency hook 15 does not perform any function under normal conditions. However, the clip 10A is pulled out from the mounting hole 21 with an excessive force when a large load with a bounce caused by the occurrence of a vehicle collision or the like is input. When it receives a load in the direction to be pulled, it functions to stop the movement in the pull-out direction on the way. Specifically, when an excessive load is applied to the clip 10 </ b> A in the direction in which the clip 10 </ b> A is pulled out from the attachment hole 21, the engagement claw 13 is in an oblique contact state with respect to the attachment hole 21. By receiving, it may be pulled in while being squeezed radially into the mounting hole 21.

  As a result, the clip 10 </ b> A moves in the direction of being pulled out from the mounting hole 21. However, even if the engaging claw 13 is pulled out from the mounting hole 21 due to the load described above, the restriction surface 15A of the emergency hook 15 at the tip of the engaging claw 13 is hooked on the back side surface 20B around the mounting hole 21. This prevents the clip 10 </ b> A from being pulled out of the attachment hole 21. Since the regulation surface 15A of the emergency hook 15 rises from the inner side surface (side surface outside the vehicle) in the width direction of the main body 11 at an angle close to the vertical, it is formed on the rear side surface 20B of the mounting portion 20. It is hooked in a state where it can exert a strong regulation force in a form of substantially surface contact.

  As shown in FIGS. 5 to 7, the interference portion 16 is a corner region on the base side in the slope portion 13 </ b> C on the back side of the engaging claw 13 described above, that is, an end region in the radial direction of the slope portion 13 </ b> C on the back side. It is formed in a shape that is overlaid. Specifically, as shown in FIG. 8, the interference portion 16 is engaged with a corner portion between a slope portion 13 </ b> C on the back side of the engaging claw 13 and an inner side surface portion (side surface portion on the vehicle outer side) in the width direction of the main body portion 11. The inclined surface portion (hatched build-up portion in FIG. 8) that is inclined so as to face the outer side in the radial direction from the slope portion 13 </ b> C on the back side of the joint claw 13 is formed in a form of being built up.

  As shown in FIG. 7, the interference portion 16 is in a state in which the clip 10 </ b> A described above sandwiches the periphery of the attachment hole 21 from the front and back sides with the engagement claw 13 and the restriction portion 12 described above with respect to the attachment hole 21. By being inserted to the position, it is configured to be pressed against the peripheral edge (corner) of the tip into which the mounting hole 21 is inserted at an oblique angle. As a result, the clip 10A has a resilience in the form of being pushed back in the width direction and the insertion direction by the action of the repulsive force that the interference portion 16 receives from the peripheral edge portion where the mounting hole 21 is inserted. It is designed to be hung.

  However, each elastic force applied in the width direction and the insertion direction is received by the vertical surface 14 </ b> C of the guide portion 14 applied to the inner peripheral surface of the mounting hole 21 described above. At the same time, the repulsive force in the insertion direction is received by the restricting portion 12 in contact with the front side surface 20A of the mounting portion 20. Accordingly, the clip 10 </ b> A is attached to the attachment hole 21 in such a manner that the clip 10 </ b> A is not rattled in the width direction and the insertion direction due to the interference of the interference portion 16.

  In summary, the clip 10A of the present embodiment has the following configuration. That is, the clip 10A is inserted into the attachment hole 21 and attached, and is engaged with the clip 10A that is attached to the attachment rear face 20B and inserted into the attachment hole 21 so as to be prevented from being detached. The engaging claw 13 to be engaged, the restricting portion 12 applied to the front side surface 20 </ b> A of the attaching hole 21 by being inserted to the position where the engaging claw 13 is engaged with the attaching hole 21, and the restricting portion 12 being the front surface of the attaching portion 20. And an interference portion 16 that is inserted into the attachment hole 21 and elastically pressed against the back side surface 20B (corner portion) of the attachment hole 21 when it contacts the side surface 20A.

  With such a configuration, the clip 10 </ b> A is inserted into the attachment hole 21 to a position where the restricting portion 12 contacts the front side surface 20 </ b> A of the attachment portion 20, so that the engagement claw 13 engages with the attachment hole 21. The interference portion 16 is elastically pressed against the back side surface 20B (corner portion) of the attachment hole 21 (see FIG. 7). As a result, the clip 10 </ b> A is pressed in the direction of deepening the insertion into the mounting hole 21 by the elastic force of the interference portion 16. Therefore, the clip 10 </ b> A can be attached in a state where the clip 10 </ b> A is loosely packed in the direction of deepening the insertion into the attachment hole 21.

  The interference portion 16 is formed on the back side inclined surface portion 13C (back side surface portion) applied to the back side surface 20B of the mounting hole 21 of the engaging claw 13, and with respect to the peripheral edge portion where the mounting hole 21 is inserted. Thus, it is formed as an inclined surface portion that is inclined so as to be pressed at an oblique angle facing outward in the radial direction.

  With such a configuration, the clip 10A can be inserted into the appropriate shape on the back side surface 20B of the mounting hole 21 without the interference portion 16 being held only by inserting the clip 10A. In addition, the interference portion 16 can also play back the radial direction of the mounting hole 21 of the clip 10A.

  Specifically, the interference portion 16 partially extends radially outside the slope portion 13C on the back side of the engagement claw 13 in the radially inner end region of the slope portion 13C on the back side of the engagement claw 13. It is formed as a shape with a tight inclination.

  By having such a configuration, the inclined portion 13C on the back side of the engaging claw 13 removed from the interference portion 16 exhibits a strong retaining force with little inclination with respect to the back side surface 20B of the mounting hole 21. Can be set at any angle. Therefore, it is possible to provide the interference portion 16 that performs backlashing in the insertion direction of the clip 10A without reducing the retaining force of the engaging claw 13.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, the “clip” of the present invention is configured to be inserted into the mounting hole and attached in addition to the use used for assembling between the structural members of the vehicle seat support base as shown in the above embodiment. The present invention can be applied to various configurations. In addition, when applied to a seat, it can be widely applied not only to a seat for an automobile but also to a seat provided for various vehicles such as a vehicle other than an automobile such as a railway, an aircraft, and a ship. .

  Moreover, the clip may be comprised from materials other than resin, such as hard rubber and a metal. In addition to the round hole, the elliptical hole, and the polygonal hole, the attachment hole to which the clip is attached may be an irregular shape having a different shape from these. In addition, the clip can be applied in various shapes according to the shape of the mounting hole. The engaging claw, the restricting portion, and the interference portion formed on the clip may be provided at a plurality of locations in the circumferential direction of the clip, or may be provided at only one location. These shapes are not limited to those shown in the above-described embodiments. For example, the engaging claws can be elastically supported in a cantilevered manner, or the arm can be partially extended from the restricting portion. Can be applied.

  Similarly, the interference portion is not limited to the one formed in the shape of the inclined surface on the base portion of the surface portion on the back side of the engagement claw. For example, the interference portion protrudes in a direction opposite to the insertion direction to the intermediate portion or the outer portion in the radial direction of the surface portion on the back side of the engaging claw, and is elastically pressed against the back side surface of the mounting hole. It may be. The interference part has a surface that is in contact with the back side surface of the mounting hole, and the surface that is in contact with the back side surface of the mounting hole is slanted or curved so that it strikes the peripheral edge of the mounting hole.
