Description

  The present invention relates to a vehicle flap device, and more particularly to a vehicle flap device suitable for putting a buckle into a retracted state.

In a vehicle seat, a buckle that engages with a tongue of a seat belt can be easily engaged with the tongue so that the buckle protrudes upward from the seat cushion so as to be conspicuous. There is something that can be attached to.
However, when the buckle protrudes from the seat cushion in this way, when the seat back is laid down, the seat back and the buckle come into contact with each other, and problems such as wear, scratches, dents and the like appear on the seat back. Sometimes.

  Thus, in order to avoid the contact and interference between the seat back and the buckle, for example, Patent Document 1 discloses a seat belt structure including a link mechanism attached to the seat back and the buckle via an arm. Has been. This link mechanism operates in conjunction with the fall of the seat back, rotates the buckle to the storage position, and prevents the buckle and the seat back from interfering with each other.

Japanese Patent Laid-Open No. 11-124006

  However, the seat belt structure described in Patent Document 1 increases the number of parts, the number of processing steps, and the weight as much as the link mechanism is provided, which is costly and laborious to attach the link mechanism.

  Therefore, the present invention has been made in view of the above-described problems, and the object thereof is a vehicle capable of avoiding interference between the seat back and the buckle while suppressing a significant increase in the number of parts. It is to provide a flap apparatus for use.

According to the vehicle flap device of the present invention, the subject is provided at a use position and a storage position so as to be rotatable, and a buckle for holding a tongue of a seat belt, a standing position and a lying position. A flap that is movably attached to the interior of the vehicle and forms a part of a cargo compartment of the vehicle, and the flap abuts on the buckle when moving from the standing position to the lying position. This is solved by forming the buckle at a position where the buckle is rotated to the storage position.
According to the above configuration, the buckle can be prevented from interfering with the buckle by rotating the buckle to the storage position by bringing the flap into contact with the buckle, and an additional part is provided on the seat side in order to tilt the buckle. In addition, it is not necessary to form the sheet side in a special shape, and the increase in the number of parts, weight, processing man-hours, and cost can be suppressed.

Moreover, when the said flap moves to the said lying position from the said standing position, it is preferable to contact | abut to the said buckle in the fixed range in the surface which comprises the said flap.
According to the above configuration, when the flap moves the flap from the standing position to the lying position, the load applied from the buckle is concentrated on the local part of the flap by contacting the buckle within a certain range on the surface constituting the flap. Can be suppressed. For this reason, it can suppress that the malfunction (an abrasion, a crack | wound, skin fall, a dent, etc.) arises in a flap by the reaction force from a buckle. Furthermore, since it continuously contacts the buckle within a certain range of the surfaces constituting the flap, the buckle can be smoothly moved to the storage position.

The flap is pivotally attached to the inside of the vehicle, and an abutting portion of the buckle with the flap is formed in an R chamfered shape from the standing position to the lying position. The contact surface of the flap that contacts the buckle when rotating is preferably curved along the rotation direction of the buckle.
According to the above configuration, the chamfer is rounded on the buckle and the contact surface of the flap is curved along the rotation direction of the buckle, so that the flap contacts the buckle not by line contact but by surface contact. It becomes. For this reason, when a buckle contact | abuts to a flap, it can suppress that a stress concentrates on the local part of a buckle, and can press a buckle softly. It can suppress that the malfunction on an external appearance arises in a flap by the reaction force from a buckle.

Further, the flap is pivotally attached to the inside of the vehicle, and the rotation center position of the flap is farther from the position of the buckle in contact with the flap than the rotation center position of the buckle. It is preferable.
According to the above configuration, when the buckle is rotated, the rotation center position of the flap is farther away from the position contacting the flap than the rotation center position of the buckle, so that the buckle is softly pushed down with a small force. The buckle can be stored smoothly. For this reason, when the reaction force of a buckle is added to the contact part contact | abutted to a buckle, it can suppress that the malfunction on an external appearance generate | occur | produces in the said part.

The flap is pivotally attached to the interior of the vehicle, and the buckle includes a seat cushion and a seat back pivotally connected to the seat cushion. It is preferable that the rotation center position of the flap is located at a position farther from the contact portion with the flap in the buckle than the rotation center position of the seat back.
According to the above configuration, since the rotation center position of the flap is located farther from the buckle than the rotation center of the seat back, the seat back is applied to the buckle in order to rotate the buckle from the use position to the storage position. Compared with the case where it contacts, when making a flap contact | abut to a buckle, a buckle can be pushed down with small force and a buckle can be stored smoothly. For this reason, it can suppress that the malfunction on an external appearance generate | occur | produces in the flap contact | abutted to a buckle rather than the case where a buckle is contact | abutted to a seat back.

Further, it is preferable that the flap is formed in the left-right direction longer than the seat length for one person in the vehicle seat in the left-right direction of the vehicle seat.
According to the above configuration, the length of the flap in the left-right direction of the vehicle seat is formed to be longer than the length of the vehicle seat for one person, so that the operator can form the flap at a position that contacts the buckle. The flap can be easily rotated by securing a length that allows the flap to touch the flap.

Further, the buckle has an abutting portion capable of abutting on the flap, and the corresponding abutting portion is made of a cushioning material, and preferably when the flap abuts when moving from the standing position to the lying position. .
According to the said structure, the contact part of the buckle contact | abutted when a flap moves from a standing position to a lying position consists of a buffer material, and the impact at the time of a flap and a buckle contacting is relieve | moderated. be able to.

The buckle includes a buckle body and a support arm that supports the buckle body, and the support arm is configured to be pivotable between the use position and the storage position of the buckle. The buckle body and the support arm are attached to the floor side, and are pivotally connected by a rotation shaft in a direction along a rotation direction between the use position and the storage position of the buckle. And preferred.
According to the above-described configuration, the buckle body and the support arm are connected to the buckle body in such a manner that the buckle body and the support arm can be rotated by the rotation shaft in the direction along the rotation direction of the buckle use position and the storage position. Since the buckle body rotates with respect to the support arm when it comes into contact with the arm, stress applied to the buckle body can be reduced.

According to the present invention, it is possible to avoid interference between the seat back and the buckle, and it is not necessary to provide an additional part on the seat side or to form a special shape on the seat side in order to tilt the buckle. Increases in man-hours and costs can be suppressed.

The embodiment described below is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. That is, the present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.

  Hereinafter, a vehicle will be described as an example of a vehicle to which the vehicle flap device according to the present embodiment is attached. However, the present invention can be applied to vehicles other than vehicles, and can be applied to ships, aircraft, industrial machines, and the like.

  In the following description, “left and right” means the left and right direction when the occupant looks at the front when the vehicle seat is seated, and the left and right direction is also referred to as the seat width direction. The “front-rear direction” means the front-rear direction when the occupant is seated on the vehicle seat.

(About the configuration of the flap device F)
First, a flap device F according to this embodiment as a vehicle flap device will be outlined with reference to FIGS. 1 is a rear perspective view showing a rear seat set RS according to an embodiment of the present invention, and FIG. 2 is a side view showing a flap device F in a state where the flap 4 is erected. FIG. 3 is an enlarged side view showing a portion where the buckle 3 is attached, and shows a state in which the anchor bracket 2a is exposed by removing a cover portion 2b described later of the base frame 2. .
The flap device F is a device for bringing the flap 4 into contact with the buckle 3 shown in FIG. 2 attached to the rear seat set RS and rotating the buckle 3 to the retracted state when the flap 4 is laid down.

  Specifically, the flap device F is located on the inner side in the vehicle width direction of the vehicle seats SA and SB constituting the rear seat set RS, and is located behind the rear seat set RS, and is a vehicle luggage compartment. And a flap 4 forming a part of the main body.

The rear seat set RS according to the present embodiment is a set of rear seats of a vehicle, and includes vehicle seats SA and SB as adjacent vehicle seats as shown in FIG.
Since the vehicle seat SA and the vehicle seat SB according to the present embodiment are symmetrically configured, the vehicle seat SA provided on the right side inside the vehicle will be described with reference to FIG.

  The vehicle seat SA includes a slide rail 1, a base frame 2 mounted on the slide rail 1, a buckle 3, a seat cushion S1, and a seat back S2 rotatably connected to the seat cushion S1. Prepare mainly.

  The slide rail 1 is configured to be slidable in the front-rear direction with respect to a floor (not shown) including a base frame 2, a seat cushion S1, and a seat back S2. The slide rail 1 constitutes a known slide mechanism so as to be slidable in the front-rear direction by pulling a strap 5 that penetrates the flap 4 and protrudes toward the cargo compartment side.

2 and 3, the base frame 2 includes an anchor bracket 2a and a cover portion 2b that covers the anchor bracket 2a. The base frame 2 extends along the upper rail of the slide rail 1 and is attached to the upper rail. ing.
The anchor bracket 2 a is a member that is attached to the slide rail 1 by rotatably supporting a buckle 3, strictly speaking, a support arm 3 a to be described later in the buckle 3. The anchor bracket 2a is on the rear side of the center of the base frame 2 in the front-rear direction, and is formed in a substantially L shape when viewed in the front-rear direction.

An anchor 3c as a rotation center provided at the lower end portion of the buckle 3 (support arm 3a described later) is rotatably attached to the side surface of the anchor bracket 2a. In addition, a pivot shaft 12 for the seat back S2 is provided in the vicinity of the upper end, which is the rear side of the portion where the anchor 3c of the base frame 2 is attached.
The anchor bracket 2a is fixed to the upper rail of the slide rail 1 with bolts and nuts at the bottom surface (that is, below the side surface).

  The buckle 3 is for holding the tongue 10a of the seat belt 10, and is connected to the anchor bracket 2a via the anchor 3c so as to be rotatable between the use position and the storage position. ing. Here, the use position is the position when the buckle 3 is erected as shown in FIGS. 2 to 4, and the storage position is the position when the buckle 3 is lying down as shown in FIG. 5. It is.

The buckle 3 includes an anchor 3c serving as a rotation center, a support arm 3a supported by the anchor 3c, and a buckle body 3b connected to the support arm 3a and locking the tongue 10a of the seat belt 10. Yes.
The anchor 3c is attached to the anchor bracket 2a of the base frame 2 as described above. A coil spring (not shown) is attached to the anchor 3c, and the buckle 3 is urged by the coil spring in a direction in which it is erected. Due to the urging by the coil spring, the buckle 3 comes to stand in a natural state.
The anchor 3c has a position where the buckle 3 stands when the seat belt 10 is used, and the buckle 3 is stored in the front lower side when the seat back S2 falls and the seat belt 10 is not used. The position is the center of rotation when the position of the buckle 3 is displaced.

  One end of the support arm 3a is supported by the anchor 3c, and the buckle body 3b is connected to the other end. The buckle 3 is urged by the coil spring, and the support arm 3a moves slightly forward as it goes upward in a state where an external force other than the urging force from the coil spring is not applied to the buckle 3. So as to extend diagonally.

  The buckle body 3b is a position where it can abut against the abutment surface 4ba of the flap 4. The abutment portion 3ba at the upper end and the rear end alleviates the impact when abutting on the flap 4, and the flap 4 In order to prevent scratches from occurring, the buffer member 3bc is provided for preventing abnormal noise. Here, the buffer material 3bc is a member made of, for example, a resin material such as a rubber material or an elastomer, a foamed resin material such as a urethane pad, or a nonwoven fabric such as a needle punch.

  Note that it is preferable that the cushioning material 3bc is provided only at the upper end and the rear end of the buckle body 3b because the above-described shock relaxation and generation of abnormal noise can be suppressed. However, the cushioning material according to the present invention is not limited to such a configuration, and may be provided at least at a position capable of contacting the contact surface 4ba. For example, the buffer material may be provided on the rear side of the buckle body 3b, the upper side of the buckle body 3b, or the entire buckle body 3b in consideration of assembly workability and ease of molding.

  The seat back S2 is rotatably connected to the rear end portion of the seat cushion S1 by a connecting arm 11. Notches 6 cut out inward in the seat width direction are formed at lower portions on both sides in the seat width direction of the seat back S2. Due to the notch 6, the buckle body 3b of the buckle 3 is exposed to the flap 4 side beyond the seat back S2. For this reason, as will be described later, the rotating plate 4b constituting the flap 4 comes into contact with the buckle body 3b when rotating from the standing position to the lying down position, and rotates the buckle 3 to the storage position. .

  In the present embodiment, since the notch 6 is formed in the seat back S2, when buckling the seat back S2, the buckle 3 does not interfere with the seat back S2 from the use position by the rotating plate 4b. Rotates to the storage position. However, the notch 6 is not always necessary. For example, there may be a configuration in which there is a gap between the vehicle seat SA and the vehicle seat SB and the buckle 3 is exposed to the rear of the rotation plate 4b beyond the seat back S2. With such a configuration, the buckle 3 can be rotated from the use position to the storage position by the rotation plate 4b without interfering with the seat back S2.

The flap 4 includes a fixed plate 4a fixed to the vehicle body and constituting a part of the cargo compartment, and a rotating plate 4b that is rotatably attached to a front end portion of the fixed plate 4a by a folding start point 4c that is a rotation center. , Is composed of.
The fixed plate 4a is a floor board that forms a part of the lower surface of the luggage compartment.
The rotating plate 4b is connected to the front end portion of the fixed plate 4a so that it can be rotated by a folding start point 4c formed of a thin hinge so as to be bent between a standing position and a lying position. There is an abutment surface 4ba that abuts the buckle body 3b on the front side in the standing state of the rotating plate 4b. The abutting surface 4ba is curved with a central portion being separated from the seat back S2, in other words, having a circular arc cross section formed so as to cover the buckle 3 up and down along the rotation direction of the buckle 3. It has a curved shape.

  In the vehicle width direction (left-right direction), the width w2 of the rotating plate 4b is formed longer in the vehicle width direction than the seat length for one of the vehicle seats SA and SB, that is, the seat width w1 shown in FIG. ing. Since the rotating plate 4b is formed in this manner, the rotating plate 4b is disposed at a position where the rotating plate 4b contacts the buckle body 3b of the buckle 3 when the rotating plate 4b is laid down. Meanwhile, the seat back S2 can be easily pushed down. Specifically, the length that allows the operator to touch the rotating plate 4b can be secured, so that the operator can easily touch the rotating plate 4b and directly tilt the rotating plate 4b, and indirectly seat back. It ’s easier to defeat S2.

  Further, a biasing member (not shown) such as a coil spring is attached to the folding starting point 4c, and the rotating plate 4b is biased toward the seat back S2 by the biasing member. When the operator lies down the seat back S2 by the urging force of the urging member, the rotating plate 4b also falls down as the seat back S2 falls down. And the rotation board 4b will function as a floor board, when it will be in a lying state.

(About the buckle storage method using the flap device F)
Next, a method for storing the buckle 3 using the flap apparatus F having the above configuration will be described with reference to FIGS. 4 and 5 in addition to FIG. 4 is a side view showing the flap device F with the flap 4 in contact with the buckle 3. FIG. 5 is a side view showing the flap device F with the flap 4 lying down.

  First, in the rotation process, by operating a lever (not shown), the seat back S2 is moved from the standing position, which is a seatable position shown in FIG. 2, to the lying position, which is a non-sitting position shown in FIG. Rotate. Then, as the seat back S2 falls, the rotating plate 4b of the flap 4 also turns from the standing position toward the falling position by the biasing force of a coil spring (not shown) attached to the folding start point 4c of the flap 4. To do.

  When the seat back S2 is rotated, the seat cushion S1 is connected to the seat back S2 by the connecting arm 11, so that the seat cushion S1 moves downward, depending on the overturning about the rotation axis 12 of the seat back S2. And it will move ahead. Specifically, the seat cushion S1 moves as described above by relatively rotating around the rotation support shaft between the connecting arm 11 and the seat back S2.

  When the seat back S2 falls, the notch 6 is formed in the portion of the seat back S2 that intersects the buckle 3 as described above. Due to the notch 6, the buckle body 3b of the buckle 3 is exposed behind and above the seat back S2 beyond the seat back S2. When the rotating plate 4b is rotated toward the lying position, the contact surface 4ba of the rotating plate 4b contacts the contact portion 3ba of the buckle body 3b as shown in FIG. Become.

  As described above, the buckle 3 is attached to the base frame 2 so as to be inclined obliquely forward. For this reason, in the storing step, when the rotating plate 4b rotates further downward with the rotating plate 4b in contact with the contact portion 3ba, the buckle 3 that contacts the rotating plate 4b is centered on the anchor 3c. , Turn forward and downward. And as shown in FIG. 5, the buckle 3 will rotate to the accommodation position. The resultant force between the weight of the contact surface 4ba and the urging force of the coil spring attached to the folding start point 4c is set larger than the urging force of the coil spring attached to the anchor 3c. For this reason, the buckle 3 is rotated from the standing position to the storage position by being pressed from the flap 4 against the urging force of the coil spring applied from the anchor 3c.

  As described above, the side surface portion of the anchor bracket 2a in which the buckle 3 is pivotally supported by the anchor 3c is provided above the bottom surface portion fixed to the slide rail 1 of the anchor bracket 2a. For this reason, when the flap 4 contacts the buckle 3 and a load is applied to the buckle 3 from the flap 4, the buckle 3 rotates forward and downward, so that the load applied to the buckle 3 is reduced. For this reason, when the contact part 3ba of the buckle 3 is made of a resin material in particular, it is possible to suppress the occurrence of defects such as scratches.

  Further, by bringing the flap 4 into contact with the buckle 3 and rotating the buckle 3 to the storage position, an additional part for tilting the buckle 3 is provided on the seat back S2, or the seat back S2 is formed in a special shape. There is no need. For this reason, the increase in the number of parts, weight, processing man-hours, and cost can be suppressed. Moreover, since it becomes possible to make the flap 4 into a fall state and to rotate the buckle 3 to the storage position, workability at the time of securing the luggage compartment by tilting the flap 4 is improved.

(Relationship between size and arrangement of buckle 3 and flap 4)
A distance between the rotation center position of the rotation shaft 12 that is the rotation center of the seat back S2 and the contact portion 3ba that contacts the rotation plate 4b in the buckle 3 is a distance d1. When the distance between the rotation center position of the folding start point 4c of the flap 4 and the contact portion 3ba is a distance d2, the distance d2 is larger than the distance d1. That is, the position of the folding start point 4 c that is the rotation center of the flap 4 is located farther from the contact portion 3 ba than the rotation shaft 12.

  For this reason, when the flap 4 is brought into contact with the buckle 3 in order to rotate the buckle 3 from the use position to the storage position, the buckle 3 is smaller than when the seat back S2 is brought into contact with the buckle 3. Can be pushed down with force. Therefore, the buckle 3 can be smoothly rotated to the storage position.

The detailed reason is that, when the seat back S2 does not have the notch 6, the rotation of the seat back S2 around the rotation shaft 12 at the portion where the seat back S2 comes into contact with the contact portion 3ba of the buckle 3 is compared. This is because the rotation locus centering on the folding start point 4c of the portion where the contact surface 4ba of the moving plate 4b contacts the contact portion 3ba of the buckle 3 becomes large.
For this reason, when the buckle 3 is brought into contact with the flap 4, the buckle 3 is brought into contact with the flap 4 in comparison with the degree of appearance defects caused in the seat back S2 by the reaction force from the buckle 3 when the buckle 3 is brought into contact with the seat back S2. The degree of appearance defects can be reduced.

  Furthermore, if the distance between the position of the anchor 3c that is the rotation center of the buckle 3 and the contact portion 3ba is a distance d3, the distance d2 is larger than the distance d3. That is, the position of the folding start point 4c of the rotating plate 4b is farther from the contact portion 3ba than the position of the anchor 3c.

As described above, the contact surface 4ba comes into contact with the contact portion 3ba away from the rotation center of the buckle 3, so that a load causing the buckle 3 to generate torque necessary for rotation is applied from the rotation plate 4b to the buckle 3. Can be effectively applied. For this reason, the buckle 3 that rotates about the anchor 3c can be softly pushed down with a small force, and the buckle 3 can be smoothly rotated to the storage position.
Furthermore, even if a reaction force from the buckle 3 is applied to the contact surface 4ba that contacts the buckle 3, the reaction force can be suppressed to a small value, and thus it is possible to suppress occurrence of defects in appearance on the contact surface 4ba. it can.

Further, when the rotating plate 4b rotates from the standing position to the lying down position, the rotating plate 4b comes into contact with the buckle 3 in a certain range on the contact surface 4ba constituting the flap 4, so that the rotating plate 4b becomes the buckle 3. When rotating while abutting on the abutting portion, the abutting location changes according to the pivoting position. Therefore, it can suppress that the load which the rotation board 4b applies from the buckle 3 concentrates locally. For this reason, it can suppress that the malfunction on an external appearance arises in the rotation board 4b by the reaction force from the buckle 3. FIG.
Further, when the rotating plate 4b rotates from the standing position to the lying position, the contact surface 4ba contacts the buckle 3 continuously instead of intermittently, so that the buckle 3 is smoothly stored. Can be moved to.

  Further, as described above, the contact surface 4ba of the rotating plate 4b is formed to be curved in a circular arc shape along the rotating direction of the buckle 3. Therefore, as shown in FIG. 6, when the contact portion 3bb of the buckle body 3b is formed in an R chamfered shape, the contact surface 4ba is not in line contact with the buckle body 3b but in surface contact. It will abut. For this reason, when the buckle 3 abuts against the abutment surface 4ba, it is possible to suppress the concentration of stress on the local part of the buckle 3 and press the buckle 3 softly. For this reason, it can suppress that the malfunction on an external appearance arises in the contact surface 4ba of the flap 4 by the reaction force from the buckle 3. FIG.

  As described above, the buckle 3 moves together with the base frame 2 in the front-rear direction by the slide rail 1. Thus, even if the buckle 3 moves to either the front or back position, when the rotating plate 4b of the flap 4 is rotated to the lying position, the upper end of the buckle body 3b of the buckle 3 and the rear end portion thereof The size of the rotating plate 4b and the position of the flap 4 are set so that they can come into contact with each other.

<Other embodiments>
In the rear seat set RS according to the above-described embodiment, the example in which one flap device F is disposed so as to straddle the adjacent vehicle seats SA and SB has been described. It is not limited to such a configuration.
For example, as shown in FIG. 7, a flap device F1 may be provided that includes flaps 4R and 4L that are provided separately for each of the vehicle seats SA and SB and are independently rotatable. Here, FIG. 7 is a rear perspective view showing a rear seat set RS1 including a flap device F1 according to another embodiment.

With the flap device F1 having such a configuration, when only the vehicle seat SA is laid down while only the flap 4R is laid down, only the buckle 3 provided on the side of the vehicle seat SA is laid down with the flap 4R. be able to. Naturally, when only the vehicle seat SB is laid down while only the flap 4L is laid down, only the buckle 3 provided on the side of the vehicle seat SB can be laid down with the flap 4L.
In other words, the flaps 4R and 4L can be laid down while the buckle 3 is individually laid down according to the lying state of the vehicle seats SA and SB. Can be formed.

<Modification>
Next, a buckle 13 according to a modification will be described with reference to FIG. FIG. 8 is a schematic diagram showing the behavior of the buckle 13 when it comes into contact with the flap 4.
The buckle body 3b and the support arm 3a in the buckle 13 are rotatably connected by a rotation shaft 13a.

  Specifically, the buckle body 3b that is rotatably connected to the support arm 3a can be rotated in a direction along the rotation direction between the use position and the storage position of the buckle 13 by the rotation shaft 13a. It has become. In other words, the buckle body 3b is rotatable with respect to the support arm 3a in the same direction as the rotation direction of the support arm 3a with respect to the anchor 3c.

Since the buckle 13 is configured in this way, when the flap 4 comes into contact with the buckle body 3b, the buckle body 3b rotates with respect to the support arm 3a, thereby reducing the stress applied to the buckle body 3b. be able to.
Specifically, when the flap 4 contacts the buckle body 3b and the buckle body 3b rotates, the load for rotating the buckle 13 together with the support arm 3a and the buckle body 3b rotate with respect to the support arm 3a. It will be divided into the load to make it. For this reason, the stress applied to the buckle body 3b is reduced, and it is possible to suppress defects such as scratches caused by the flap 4 coming into contact with the buckle 13.

Furthermore, the distance between the rotation shaft 13a and the contact portion 3bb is shorter than the distance between the anchor 3c and the contact portion 3bb. For this reason, when the flap 4 contacts the contact portion 3bb of the buckle body 3b and rotates to the lying position side, the speed at which the buckle 13 according to the modification tilts toward the storage position side of the buckle body 3b is as described above. The speed of the buckle 3 according to the embodiment is faster than the inclination of the buckle body 3b.
Therefore, since the direction of the load applied from the flap 4 to the buckle body 3b is close to the turning direction of the buckle 13 around the anchor 3c at an early timing, the buckle 13 is smoothly moved to the storage position. be able to.

  Moreover, when the flap 4 contacts the buckle body 3b, a large collision load is applied to the buckle body 3b. For this reason, when the buckle 13 is arranged so that the buckle body 3b is rotated with respect to the support arm 3a in the initial stage as compared with the stage after the rotation of the buckle body 3b is stopped, the stress applied to the buckle body 3b. It is effective to reduce.
