JP 2002-37007 A Japanese Patent No. 3633537

  In the case of the airbag device disclosed in Patent Document 1, since the pin member and the grommet are necessary, there is a problem that the structure is complicated, the number of parts is large, and the manufacturing cost is increased.

  Moreover, in the fixture of the said patent document 2, in order to accommodate a strip | belt-shaped movement control part, since a big accommodating part is required on the garnish side, there existed a problem that a garnish structure became complicated and it was difficult to make it thin. Furthermore, when assembling the fixture to the garnish, after inserting the flange portion at the tip of the movement restricting portion into the elongated hole-shaped attachment hole, rotating the fixture 90 degrees and further pushing it in, the movement restriction Since the garnish is connected to the vehicle body panel via the fixture by engaging the engagement portion of the base end with the attachment hole and then engaging the locking leg with the attachment hole of the vehicle body panel, There was a problem with sex. In addition, it is difficult to remove the locking leg once engaged with the mounting hole from the vehicle body panel, which causes inconvenience when parts are replaced.

  Accordingly, an object of the present invention is to provide a two-stage locking clip that can easily connect an interior member to a panel member, and can be easily detached from the panel member when necessary, and can further reduce costs. It is in.

  In order to achieve the above object, a first aspect of the present invention includes a substantially circular central portion formed in a panel member with a head engaged with a slit-like groove formed in an interior member, and a circle at the central portion. A leg portion is engaged with an attachment hole having a slit-like end portion extending in the opposite direction from a substantially opposing portion of the circumference to connect the interior member to the panel member, and the engagement of the leg portion. In a two-stage locking clip that is combined in two stages, a head that engages with the slit-shaped groove, a neck that extends from one side of the head and is inserted into the slit-shaped groove, And a leg portion extending from the lower surface of the flange portion, and the leg portion is extended with a thickness and a width that can be inserted into the mounting hole. The base side is wider than the maximum width of the mounting hole, and the tip side is the mounting side. A stem portion that is narrower than the maximum width of the attachment hole and a base portion side of the stem portion, which passes through the attachment hole and engages the back surface thereof, and a strong pulling force acts in the engaged state. A first elastic engagement piece that is sometimes elastically deformed and can be extracted from the attachment hole, and provided at the distal end side of the stem portion, and is at an angle that intersects the longitudinal direction of the attachment hole. And a second elastic engagement piece that is allowed to pass through the attachment hole when positioned in the same direction as the longitudinal direction of the attachment hole. It is to provide.

  According to the above invention, the neck portion is inserted into the slit-like groove of the interior member and the head portion is engaged, so that it can be connected to the interior member, and the leg portion is inserted into the mounting hole of the panel member. By engaging the first elastic engagement piece with the mounting hole, the interior member and the panel member can be easily connected with one touch.

  In this state, when a strong peeling force acts on the interior member and a strong pulling force acts on the leg portion of the clip, the first elastic engagement piece is elastically deformed and extracted from the mounting hole, and the stem portion A second elastic engagement piece provided on the distal end side engages with the attachment hole.

  As a result, it is possible to prevent the interior member from being completely separated from the panel member by re-engaging the interior member with the panel member being separated by a predetermined distance. When the first elastic engagement piece is engaged with the attachment hole, the stem portion cannot rotate with respect to the attachment hole. Therefore, when the first elastic engagement piece is elastically deformed and pulled out from the attachment hole. The second elastic engagement piece provided on the distal end side of the stem portion can be reliably arranged in a direction intersecting the longitudinal direction of the mounting hole.

  Therefore, the clip of the present invention is suitable, for example, when an airbag is accommodated and fixed between the interior member and the panel member. When the airbag is activated, the interior member is predetermined with respect to the panel member. It is possible to prevent the interior member from completely flying away while allowing the airbag to bulge outward by being separated by a distance of.

  In addition, when the clip is to be removed from the panel member, the clip can be rotated because the width of the stem portion is narrower than the center portion of the mounting hole when the tip of the stem portion is positioned at the opening of the mounting hole. By positioning the second elastic engagement piece in the same direction as the longitudinal direction of the attachment hole, the second elastic engagement piece can be extracted from the attachment hole, so that the clip can be removed relatively easily. .

  Furthermore, since the head, neck, flange, and leg can be formed integrally, the number of parts can be reduced and the cost can be reduced. In addition, it is only necessary to provide slit-shaped grooves on the interior member, and a relatively simple structure can be obtained. From this point, the cost can be reduced.

  According to a second aspect of the present invention, in the first aspect, the first elastic engagement piece has one end connected to the stem portion, the other end connected to the flange portion, and one side connected to the stem portion. Provided is a two-stage locking clip comprising a pair having a wide interval with respect to the other side and a narrow interval on the other side with respect to the stem portion and having a rotationally symmetrical shape with the stem portion interposed therebetween. .

  According to the above invention, the first elastic engagement piece has a shape that can be punched and can be formed thin to increase elasticity, and can be engaged in a wide range in the circumferential direction with respect to the central portion of the mounting hole. The engagement force can be increased. Further, since the first elastic engagement piece is composed of a pair of rotationally symmetric members with the stem portion interposed therebetween, the first elastic engagement piece can be engaged with the central portion of the attachment hole with a good balance. Furthermore, since the mold release direction of the second elastic engagement piece can be made the same as the mold release direction of the first elastic engagement piece, the mold structure is simplified and the cost can be reduced.

  According to a third aspect of the present invention, in the second aspect, when the first elastic engagement piece is engaged with the attachment hole, the first elastic engagement piece is out of the pair of side edges at both ends of the attachment hole. The distance between one side edge portion of the elastic engagement piece on the side that forms a wide interval with respect to the stem portion and the stem portion is determined by the other side edge portions of both ends of the mounting hole, The present invention provides a two-stage locking clip that is formed to be wider than the distance from the stem portion.

  According to the above invention, the width of both ends of the mounting hole through which the second elastic engagement piece passes can be increased while ensuring the maximum engagement range in the circumferential direction of the first elastic engagement piece. 2 The width of the elastic engagement piece can be ensured to the maximum. Therefore, the first elastic engagement piece can be firmly engaged with the attachment hole, and the second elastic engagement piece can be prevented from being damaged, and the clip can be securely prevented from coming off.

  According to the two-stage locking clip of the present invention, after inserting the neck portion into the slit-like groove and engaging the head portion, the leg portion is inserted into the mounting hole, and the first elastic engagement piece is engaged with the mounting hole. By combining, the interior member and the panel member can be easily connected with one touch.

  When the clip is to be removed from the panel member, the second elastic engagement piece can be extracted from the attachment hole by positioning the second elastic engagement piece of the stem portion in the same direction as the longitudinal direction of the attachment hole. This makes it possible to remove the clip relatively easily.

  Furthermore, since the head, neck, flange, and leg can be formed integrally, the number of parts can be reduced, and the interior member can also be made relatively simple, so the cost can be reduced.

The clip 10 is held stably. The second flange portion 41 elastically abuts on the upper surface of the panel member 2 and suppresses rattling or the like when the clip 10 is attached to the panel member 2.

  A leg portion 50 extends from the lower surface of the second flange portion 41. The leg portion 50 includes a plate-like stem portion 60, a first elastic engagement piece 70 provided on the base 61 side of the stem portion 60 described later, and a second elastic engagement provided on the distal end portion 65 side. It consists of a piece 80.

  The stem portion 60 extends from the center of the lower surface of the second flange portion 41 in a plate shape with a predetermined thickness T (see FIG. 4B), and is orthogonal to the long side direction of the head portion 20 and the neck portion 30. They are arranged in the direction (FIGS. 3B and 3C). More specifically, the stem portion 60 is formed to be narrower than the base portion 61 through a wide base portion 61 provided continuously with the second flange portion 41 and slopes gradually reducing in diameter from both end portions of the base portion 61. And an end portion 65 narrower than the intermediate portion 63 formed at the lower end of the slope gradually reducing in diameter from both side end portions of the intermediate portion 63.

The stem portion 60 can be inserted into the mounting hole 7. 3C, the width W1 of the base 61 is formed wider than the maximum width B1 of the mounting hole 7 (inner diameter of the central portion 8), and the base 61 is formed in the mounting hole 7. In the inserted state, the stem portion 60 cannot be rotated. The width W2 of the intermediate portion 63 is formed slightly smaller than the maximum width B1 of the attachment hole 7, and in the state where the intermediate portion 63 is disposed at the central portion 8 of the attachment hole 7 as shown in FIG. As shown in FIG. 7B, the stem portion 60 can be rotated. Further, the width W3 of the front end portion 65 is formed to be smaller than the width W2 of the intermediate portion 63.

  A pair of first elastic engagement pieces 70 and 70 are provided on both side surfaces of the base portion 61 of the stem portion 60 so as to sandwich the stem portion 60 and be rotationally symmetric with respect to the center O2. As shown in FIGS. 1 to 4, each first elastic engagement piece 70 has one end 71 connected to the vicinity of the intermediate portion 63 of the stem portion 60, and a predetermined gap with respect to the side surface of the stem portion 60. A shape in which the other end portion 73 is connected to the back surface of the second flange portion 41 through a stepped portion 72 formed in the vicinity of the second flange portion 41 extending slightly obliquely toward the second flange portion 41 side. There is no.

  The first elastic engagement piece 70 is inserted by being elastically deformed inward when inserted into the attachment hole 7 due to a gap formed between the stem portion 60 and the stepped portion 72 is the back surface of the attachment hole 7. Engage with the periphery (see FIGS. 4A and 4B). Similarly, even when a strong pulling force is applied with the first elastic engagement piece 70 engaged with the attachment hole 7 due to the gap, the first elastic engagement piece 70 is elastically deformed inward and attached. The first elastic engagement piece 70 can be extracted from the hole 7.

  In addition, the gap between the first elastic engagement piece 70 and the stem portion 60 described above is wide between one side of the first elastic engagement piece 70 with reference to FIGS. 3 (b) and 3 (d). The first elastic engagement piece 70 is formed at a distance S1 that is spaced apart from the other side of the first elastic engagement piece 70 at a distance S2 that is narrower than S1. As a result, the mold can be removed from both sides, and the elasticity of the first elastic engagement piece 70 is improved, and the attachment hole 7 is engaged in a wide range in the circumferential direction.

  Further, as shown in FIG. 4B, in a state where the first elastic engagement piece 70 is engaged with the central portion 8 of the attachment hole 7, the stem portion 60 has both end portions 9, 9 is not disposed at the center of the lens 9 but is displaced from the side edge portions 9a and 9b. At this time, the distance C1 between the side edge portion 9a on the side having a large distance S1 with respect to the stem portion 60 of the first elastic engagement piece 70 and the stem portion 60 is the other side edge portion 9b and the stem portion 60. It is comprised so that it may become wider than the distance C2.

  The distal end portion 65 of the stem portion 60 is provided with a pair of second elastic engagement pieces 80, 80 extending obliquely in a foot-shaped manner from both sides toward the second flange portion 41. As shown in FIG. 3 (d), each second elastic engagement piece 80 is offset from the stem portion 60 of the first elastic engagement piece 70 toward the narrow interval S2, and The stem portion 60 is configured to be rotationally symmetric with respect to the center O2. Each of the second elastic engagement pieces 80 extends until the tip portion is positioned at the intermediate portion 63 of the stem portion 60, and the upper end of the tip portion forms a flat surface. In addition, the width | variety of the 2nd elastic engagement piece 80 is set to W4 (refer FIG.3 (c)).

  The second elastic engagement piece 80 is pulled out of the attachment hole 7 by applying a strong pulling force from the state in which the first elastic engagement piece 70 is engaged with the attachment hole 7. Then, it is positioned at an angle that intersects the longitudinal direction of the mounting hole 7 (the direction in which both end portions 9 and 9 extend), and engages with the central portion 8 of the mounting hole 7 (FIG. 5 ( a), see (b)). If the stem portion 60 is rotated so that the second elastic engagement pieces 80 are arranged in the same direction with respect to the longitudinal direction of the attachment hole 7, both end portions 9, 9 of the attachment hole 7 are formed. It becomes possible to pass (see FIGS. 7A and 7B), and the clip 10 can be extracted from the mounting hole 7.

  Next, a method of using the clip 10 of the present invention having the above-described configuration and its operation and effect will be described.

  First, the neck portion 30 of the clip 10 is inserted in alignment with the slit-like groove 5 of the interior member 3 (see FIG. 1). Then, the head 20 is positioned by the inner surface of the mounting seat 4, and the head 20 and the first flange portion 40 abut on the upper and lower surfaces of the holding plate 4 b of the mounting seat 4, so that the clip 10 is attached to the mounting seat 4. The clip 10 can be connected to the interior member 3 via the mounting seat 4.

  Then, as shown in FIG. 1, the clip 10 is inserted into the attachment hole 7 by aligning the width direction of the stem portion 60 of the leg portion 50 of the clip 10 with the longitudinal direction of the attachment hole 7 of the panel member 2. Go. Then, the second elastic engagement pieces 80, 80 provided on the distal end portion 65 side of the stem portion 60 are pressed by the inner periphery of the central portion 8 of the mounting hole 7 and bent inward, and protruded to the back side of the panel member 2. When the front end reaches the back surface periphery of the central portion 8, it elastically recovers and engages with the back surface periphery of the central portion 8.

  When the clip 10 is further pushed in this state, the first elastic engagement pieces 70 and 70 on the base 61 side of the stem portion 60 are pressed against the inner periphery of the central portion 8 of the mounting hole 7 and bent inward, When protruding from the back side of the panel member 2 and the stepped portion 72 reaches the peripheral edge of the back surface of the central portion 8, it elastically recovers, and the stepped portion 72 engages with the peripheral edge of the back surface of the central portion 8. It elastically contacts the surface of the panel member 2. Thus, the clip 10 is attached to the attachment hole 7, and the interior member 3 can be connected to the panel member 2 through the clip 10 (see FIGS. 4A and 4B).

  Thus, according to the clip 10 of the present invention, the interior member 3 and the panel member can be obtained simply by inserting the neck portion 30 into the slit-like groove 5 and then inserting the leg portion 50 in alignment with the longitudinal direction of the mounting hole 7. 2 can be easily connected with one touch. Unlike the fixture of the above-mentioned Patent Document 2, there is no need to rotate it after inserting it into the mounting hole, and the mounting workability is good.

  4 (a) and 4 (b), when a strong peeling force acts on the interior member 3 and a strong pulling force acts on the leg portion 50 of the clip 10, each first elastic engagement piece 70 is applied. Is elastically deformed and extracted from the attachment hole 7, and the distal end portion of each second elastic engagement piece 80 provided on the distal end portion 65 side of the stem portion 60 is formed on the peripheral edge of the back surface of the central portion 8 of the attachment hole 7. The interior member 3 is engaged again with the panel member 2 being separated from the panel member 2 by a predetermined distance, thereby preventing the interior member 3 from being completely separated from the panel member 2 (FIG. 5). (See (a) and (b)).

  Therefore, this clip 10 can be suitably used to connect the interior member 3 that houses the airbag AB to the panel member 2 as shown in FIG. That is, in a state where the interior member 3 is connected to the panel member 2 via the clip 10, the airbag AB is activated by a collision of the automobile or the like, and the interior member 3 is pressed by the inflated airbag AB. When a force is applied to peel off the panel member 2 from the panel member 2, a strong pulling force is also applied to the leg portion 50 of the clip 10, and as described above, the interior member 3 is separated from the panel member 2 by a predetermined distance. As shown in FIG. 9, the air bag AB can bulge outwardly from the gap and prevent the interior member 3 from flying away completely. it can.

  Further, since the width W1 of the base portion 61 of the stem portion 60 is formed to be larger than the maximum width B1 of the attachment hole 7, the stem portion 60 is in a state where the first elastic engagement piece 70 is engaged with the attachment hole 7. On the other hand, the width W2 of the intermediate portion 63 of the stem portion 60 is formed slightly smaller than the maximum width B1 of the mounting hole 7, so that the second elastic engagement piece 80 is engaged with the mounting hole 7. In the combined state, the stem portion 60 can be rotated.

  Therefore, when it is desired to remove the clip 10 from the panel member 2, first, as shown in FIGS. 6A and 6B, the neck portion 30 is slid from the slit-like groove 5, and the clip 10 is removed from the interior member 3. After the removal, as shown in FIGS. 7A and 7B, the stem portion 60 is rotated to place the second elastic engagement piece 80 in the same direction as the longitudinal direction of the attachment hole 7, that is, the attachment hole. 7 so that the respective second elastic engagement pieces 80 are aligned with both end portions 9 and 9, so that the second elastic engagement pieces 80 can be pulled out of the mounting holes 7 and the clip 10 can be removed relatively easily. .

  Furthermore, in this clip 10, since the head 20, the neck 30, the first flange 40, the second flange 41, and the legs 50 can be integrally formed, the number of parts can be reduced. Thus, the cost can be reduced. Further, the interior member 3 only needs to be provided with the mounting seat 4 having the slit-like groove 5, and the structure can be made relatively simple, so that the cost can be reduced also in this respect.

  Further, in the clip 10 of the present invention, the pair of first elastic engagement pieces 70 have a wide space S1 on one side with respect to the stem portion 60, as shown in FIGS. 3 (b) and 3 (d). Since the side has a narrow interval S2 with respect to the stem portion 60, the first elastic engagement piece 70 has a shape that can be punched out, and can be formed thin to increase elasticity, and the mounting hole 7 It is possible to engage with the central portion 8 in a wide range in the circumferential direction and increase the engagement force. Further, since the first elastic engagement piece 70 is composed of a pair of rotationally symmetric members with the stem portion 60 interposed therebetween, the first elastic engagement piece 70 can be engaged with the central portion 8 of the attachment hole 7 in a balanced manner. Furthermore, since the mold release direction of the second elastic engagement piece 80 can be made the same as the mold release direction of the first elastic engagement piece 70, the mold structure is simplified and the cost can be reduced.

  Furthermore, in the clip 10 of the present invention, when the first elastic engagement piece 70 is engaged with the attachment hole 7, of the pair of side edges 9a, 9b of the both end portions 9, 9 of the attachment hole 7, The distance C1 between one side edge 9a and the stem 60 on the side that forms a wide space S1 with respect to the stem 60 of the first elastic engagement piece 70 is the distance between the other side edge 9b and the stem 60. It is provided wider than the distance C2 (see FIG. 4B).

  According to this, the width B2 of both ends 9 and 9 of the mounting hole 7 through which the second elastic engagement piece 70 passes is widened while ensuring the maximum engagement range of the first elastic engagement piece 70 in the circumferential direction. Therefore, the width W4 of the second elastic engagement piece 80 can be secured to the maximum. Therefore, the first elastic engagement piece 70 can be firmly engaged with the attachment hole 7, and the second elastic engagement piece 80 can be prevented from being damaged, and the clip 10 can be securely prevented from coming off.
