  Here, when considering a configuration with both a handle for easily pulling out the seat belt and a hammer for splitting the glass, it is usually fixed firmly to the seat belt and used as a handle. It must be used as a hammer that breaks the glass easily off the belt.

  However, if the handle is formed integrally with the seat belt bracket or fixed to the seat belt using a screw or the like, there is a problem that the handle cannot be immediately detached from the seat belt and used as a hammer. Further, when a glass splitting device is provided on a seat belt member such as a slut- ing, the glass can be broken only within a range where the seat belt extends and reaches. Further, when the hammer is swung down toward the glass, there is a problem that the seat belt becomes in the way and cannot be smashed with force. On the other hand, when it is detachably attached with a clip or the like, if the fixing force to the seat belt is weak, the seat belt is displaced when it is pulled out, causing a problem in the function as a handle.

  The present invention provides a seat belt puller that can be used as a handle for pulling out a seat belt while usually being firmly fixed to the seat belt, and can be quickly removed from the seat belt and used as a glass split hammer in an emergency. The purpose is to do.

  In order to solve the above-mentioned problems, a seat belt puller according to the present invention has a hole through which a seat belt passes, a clip portion for fixing and releasing the seat belt, a head portion having a hammer portion, and a head portion on one end side. And a neck portion to which the clip portion is connected on the other end side. The clip part is provided on one side of the hole and on the other side of the hole. The clip part is connected to the base part at the end opposite to the neck part of the base part, and is integrally formed with the base part. A movable part that can be opened and closed with a spring property, a hook part that is provided on the other side of the hole and engages with the tip of the movable part when the movable part is closed, and engagement between the hook part and the tip of the movable part And a partition portion provided between the portion and the hole. The movable portion is characterized in that the tip of the movable portion is opened away from the hook portion by bending the base portion in a closed state.

  According to such a configuration, the seat belt puller can be securely attached to the seat belt by closing the movable portion with the seat belt being passed through the hole of the clip portion and engaging the tip with the hook portion. . Moreover, since the partition part is provided between the engaging part and the hole, when the seat belt pull-out tool is mounted, the seat belt and the engaging part can be partitioned by the partition part. Thereby, when using as a handle, it can prevent that a force is not applied to an engaging part from a seatbelt, and engagement is released. On the other hand, by curving the base portion of the clip portion, the distal end of the movable portion is detached from the hook portion, and in the event of an emergency, the seat belt drawer can be easily removed from the seat belt.

  In the seat belt drawer according to the present invention, a convex portion that is convex toward the hole side is provided near the engaging portion of the movable portion, and when the movable portion is closed, the tip of the convex portion is closer to the hole side than the partition portion. In a state where the movable part is open, the tip of the convex part may be provided at a position farther from the hole than the partition part.

  According to such a configuration, when the movable part is closed, the tip of the convex part is positioned on the hole side with respect to the partition part, so that the seat belt can be pressed and firmly fixed. On the other hand, when the movable part is opened, the tip of the convex part is located farther from the hole than the partition part, so that the engaging part is opened and can be easily detached from the seat belt.

  In the seat belt puller according to the present invention, an inclined surface is provided at the tip of the movable portion, and when the movable portion is closed, the hook portion and the inclined surface come into contact with each other, and the pressure from the hook portion to the inclined surface is gradually increased. Therefore, the closed state of the movable part may be maintained by the hook part getting over the inclined surface.

  According to such a configuration, it is possible to engage with an appropriate force when closing the movable part, and it is possible to obtain a feeling that the hook part has crossed the inclined surface when engaged.

  In the seat belt puller of the present invention, the head portion has an outer portion having a first hardness that is softer than the clip portion, and a second hardness that is harder than the first hardness, and is located inside the outer portion. And a hole for fitting the root of the hammer portion may be provided in the inner portion.

  According to such a structure, the part which touches a user's hand as a handle becomes soft and becomes easy to grip. On the other hand, the hammer portion is firmly fixed to the hard inner portion, so that an impact can be reliably applied to the glass as a hammer.

  In the seat belt puller of the present invention, the inner portion may have a hollow structure. According to such a configuration, it is not necessary to increase the weight of the head part more than necessary due to the hollow structure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same members are denoted by the same reference numerals, and the description of the members once described is omitted as appropriate.

(Structure of seat belt drawer)
Drawing 1 (a) and (b) is a figure which illustrates a seat belt drawer tool concerning this embodiment, (a) shows a perspective view and (b) shows a sectional view.
As shown in FIG. 1A, the seat belt puller 1 according to the present embodiment is used as a handle that is attached in the middle of the seat belt SB and assists when the seat belt SB is pulled out. Furthermore, the seat belt drawer 1 according to the present embodiment is also used as a hammer for breaking glass in an emergency. Such a seat belt puller 1 according to this embodiment includes the clip portion 10, the head portion 20, and the neck portion 30.

  The clip portion 10 has a hole 10h through which the seat belt SB is passed, and is a portion that fixes and releases the seat belt SB. Details of the clip unit 10 will be described later. The head portion 20 has a shape that is easy to grip (for example, a spherical body) and has an appropriate hardness.

  The head portion 20 is provided with a sharp hammer portion 21. As the hammer portion 21, for example, a carbon tool steel formed into a conical shape and nickel-plated is used. In the present embodiment, two hammer portions 21 are provided on the head portion 20. The two hammer portions 21 are provided in directions opposite to each other. The number of hammer portions 21 may be one, or three or more. Further, the hammer portion 21 having a flat tip may be included.

  The hammer portion 21 may be covered with a cap 21c. If the cap 21c is put on, the tip of the hammer portion 21 does not have to be exposed when not used as a hammer. As a material for the cap 21c, plastic or rubber is used. What is necessary is just to remove the cap 21c when using it as a hammer.

  As shown in FIG. 1B, the head portion 20 has an outer portion 210 and an inner portion 220. The outer portion 210 has a first hardness that is softer than the clip portion 10. Since the outer portion 210 is a portion that touches the hand as a handle, it is possible to obtain ease of gripping with moderate softness. As a material of the outer portion 210, for example, a soft synthetic resin material such as an elastomer or urethane is used.

  On the other hand, the inner portion 220 has a second hardness that is harder than the first hardness. The inner portion 220 is provided with a hole 220h, and the root of the hammer portion 21 is fitted into the hole 220h. Since the inner portion 220 is hard, the hammer portion 21 can be firmly fitted. As a material of the inner portion 220, for example, polybutylene terephthalate (PBT) is used. Details of the inner portion 220 will be described later.

  The neck part 30 is a part which connects the head part 20 and the clip part 10, and the head part 20 is connected to one end side, and the clip part 10 is connected to the other end side. The outer diameter of the neck part 30 is provided smaller than the outer diameter of the head part 20. As a result, a bulge from the neck portion 30 to the head portion 20 is provided to make it easy to grasp as a handle.

  As shown in FIG. 1B, a recess 30h is provided at the end of the neck portion 30 on the clip portion 10 side, and the protrusion 10t of the clip portion 10 is fitted into the recess 30h. The neck portion 30 and the outer portion 210 of the head portion 20 are integrally formed.

  The neck portion 30 and the outer portion 210 of the head portion 20 are formed by, for example, injection molding. When manufacturing the seat belt drawer 1, each of the inner portion 220 of the head portion 20 and the clip portion 10 is separately formed in advance by injection molding. In the molding of the neck portion 30 and the outer portion 210, it is desirable to perform injection molding in which the inner portion 220 and the clip portion 10 are inserted. This makes it possible to incorporate the inner portion 220 inside the outer portion 210 and to reliably join the neck portion 30 and the clip portion 10 by a single molding.

(Clip structure)
Next, the detailed structure of the clip unit 10 will be described.
The clip part 10 has a base part 11 provided on one side of the hole 10h, a movable part 12, a hook part 13 and a partition part 14 provided on the other side of the hole 10h. In this embodiment, the base part 11, the movable part 12, the hook part 13, and the partition part 14 are integrally formed of plastic. For example, polypropylene (PP) or polycarbonate (PC) is used as the plastic material.

  The movable part 12 is connected to the base part 11 via the U-shaped part 10 u at the end of the base part 11 opposite to the neck part 30. That is, the movable part 12 is provided so as to go around from the base part 11 provided on one side of the hole 10h to the other side of the hole 10h via the U-shaped part 10u. Thereby, the base portion 11 and the movable portion 12 face each other, and a hole 10h is provided between them. The movable part 12 is provided so as to be openable and closable by a spring property by integral molding with the base part 11. The movable part 12 is biased to the opening side by the spring property.

  The hook portion 13 is a portion that engages with the tip of the movable portion 12 when the movable portion 12 is closed. The hook portion 13 is provided with a claw 131, and the claw 131 is hooked by the claw 121 at the tip of the movable portion 12, whereby the movable portion 12 can be held closed.

  The partition part 14 is provided between the engagement part LK between the claw 131 of the hook part 13 and the claw 121 of the movable part 12 and the hole 10h. The partition portion 14 is provided so as to extend in a plate shape from the hole 10 h side of the hook portion 13. That is, the partition part 14 is extended longer than the nail | claw 131 of the hook part 13, and covers the engaging part LK.

  As described above, the partition 14 is provided between the engaging portion LK and the hole 10h, so that when the seat belt puller 1 is attached to the seat belt SB, the seat belt SB and the engaging portion LK The space can be partitioned by the partitioning section 14. As a result, even if a force is applied from the seat belt SB to the engagement portion LK side, the partition portion 14 prevents the force from being transmitted to the engagement portion LK, thereby preventing the engagement from being released. .

  2 (a) to 2 (c) are diagrams for explaining opening and closing of the clip part, (a) is a side view in a closed state, (b) is a side view in an open state, and (c) is an engaging portion. FIG. In the following description, for convenience of explanation, the base portion 11 side from the movable portion 12 is referred to as the lower side (lower side), and the opposite is referred to as the upper side (upper side).

  As shown in FIG. 2A, when the movable part 12 is closed, the claw 121 of the movable part 12 is caught below the claw 131 of the hook part 13. Although the movable part 12 has a spring property in the opening direction, the closed state can be maintained by hooking the claw 121 of the movable part 12 below the claw 131 of the hook part 13.

  Here, the movable portion 12 is provided with a first convex portion 12a and a second convex portion 12b that are convex toward the hole 10h. On the other hand, the base portion 11 is provided with a third convex portion 11a that is convex toward the hole 10h. The 3rd convex part 11a is arrange | positioned between the 1st convex part 12a and the 2nd convex part 12b. Accordingly, when the movable portion 12 is closed while the seat belt SB is passed, the seat belt SB can be firmly fixed so as to be bitten by the first convex portion 12a, the second convex portion 12b, and the third convex portion 11a. it can.

  As shown in FIG. 2B, when the claw 121 of the movable portion 12 is above the claw 131 of the hook portion 13, the movable portion 12 is opened due to the spring property of the movable portion 12. When the movable portion 12 is opened, a gap is generated in the engaging portion LK. The seat belt SB is inserted from this gap and passed through the hole 10h. After passing the seat belt SB through the hole 10h, the movable portion 12 is closed and the claw 121 is engaged with the claw 131 of the hook portion 13 (see FIG. 2A). As a result, the seat belt SB can be sandwiched between the clip portions 10 and the seat belt drawer 1 of the present embodiment can be securely fixed.

  To remove the seat belt drawer 1 from the state of being fixed to the seat belt SB, the movable portion 12 is opened as shown in FIG. 2B, and the seat belt SB is removed from the gap generated in the engaging portion LK. do it. On the contrary, in order to attach the seat belt drawer 1 to the seat belt SB, the movable portion 12 is opened as shown in FIG. 2B, and the seat belt SB is passed through the hole 10h from the gap of the engaging portion LK. After that, the movable part 12 may be closed.

Next, the tip of the claw 121 of the movable part 12 will be described in detail.
As shown in FIG. 2C, in this embodiment, an inclined surface 121 f is provided at the tip of the claw 121 of the movable portion 12. The inclined surface 121f is provided so as to approach the claw 131 of the hook portion 13 from the bottom to the top. Thereby, when closing the movable part 12, the nail | claw 131 of the hook part 13 and the inclined surface 121f contact | abut, and the pressure from the nail | claw 131 to the inclined surface 121f becomes strong gradually. Then, when the claw 131 gets over the inclined surface 121f, the claw 121 of the movable part 12 enters the lower side of the claw 131 of the hook part 13, and the movable part 12 can be held in a closed state.

  By providing such an inclined surface 121f, an appropriate force can be applied when the movable portion 12 is closed (on the way of closing). That is, when the movable portion 12 is closed, the inclined surface 121f and the claw 131 come into contact with each other, and when the movable portion 12 is pushed in from there, the claw 131 is gradually pushed by the inclined surface 121f by the action of the angle of the inclined surface 121f. Will go. Eventually, the claw 131 gets over the inclined surface 121f, and the claw 121 of the movable portion 12 is engaged with the lower side of the claw 131 of the hook portion 13. At this time, the engagement is completed with a clicking feel of a click.

  Further, in a state where the movable portion 12 is closed, the tip of the first convex portion 12 a provided closer to the engaging portion LK of the movable portion 12 is located closer to the hole 10 h than the partition portion 14. On the other hand, in a state where the movable portion 12 is open, the tip of the first convex portion 12a is located farther from the hole 10h than the partition portion 14.

  According to such a positional relationship, when the movable portion 12 is closed, the seat belt SB can be pressed and firmly fixed by the tip of the first convex portion 12a. Further, since the seat belt SB is pressed toward the base portion 11 by the first convex portion 12a, the seat belt SB can be separated from the partition portion 14.

  On the other hand, when the movable portion 12 is opened, the tip of the first convex portion 12a is positioned farther from the hole 10h than the partition portion 14, and therefore the engaging portion LK expands and can be easily removed from the seat belt SB. it can. Further, when the seat belt SB is passed through the hole 10h from the expanded engagement portion LK, the first convex portion 12a is not obstructed and the seat belt SB can be smoothly passed through the hole 10h.

(Operation to open and close the clip part)
FIGS. 3A and 3B are schematic views for explaining an operation for opening and closing the clip portion.
In the seat belt drawer 1, in order to open the movable portion 12 of the clip portion 10, it can be easily opened by applying a force to bend the base portion 11.

  First, as shown in FIG. 3A, a force is applied with the thumb so that the lower side of the base portion 11 facing the engaging portion LK is warped while the movable portion 12 is closed. At this time, the thumbs of both hands are attached to the lower side of the base part 11 and the base part 11 is bent gently with the left and right hands. Thereby, as shown in FIG. 3B, the engaging portion LK is expanded, and the engagement between the claw 131 of the hook portion 13 and the claw 121 of the movable portion 12 is released. When the engagement is disengaged, the movable part 12 is opened by the spring property of the movable part 12.

  On the other hand, when closing the movable part 12, a force is applied to slightly warp the base part 11 with a thumb attached to the lower side of the base part 11 in the same manner as when the movable part 12 is opened. Try to close. Since the engagement portion LK is expanded by slightly warping the base portion 11, the claw 121 of the movable portion 12 easily gets over the claw 131 of the hook portion 13 and is easily engaged.

  When the claw 121 of the movable part 12 gets over the claw 131 of the hook part 13, it is possible to obtain an engaged feeling by a click feeling “click”. After the engagement, when the force applied to the base portion 11 is removed, the engaging portion LK is closed and the movable portion 12 can be reliably fixed.

  Note that the engagement portion LK is desirably provided near the center of the entire length of the seat belt puller 1 so that the movable portion 12 can be easily opened and closed by curving the base portion 11. Thus, the base portion 11 can be easily warped with the left and right hands around the engaging portion LK, and the opening / closing operation can be performed only by applying a light force.

  Moreover, when closing the open movable part 12, the nail | claw 131 will be pushed by the inclined surface 121f by the effect | action of the angle of the inclined surface 121f (refer FIG. 2). The base portion 11 is bent by this force. Accordingly, even if the base portion 11 is not actively bent, the same state as when the base portion 11 is bent by pushing the movable portion 12 strongly is obtained, and the claw 121 of the movable portion 12 is engaged with the hook portion 13. It can be engaged with the lower side of the claw 131.

  Here, immediately after the claw 131 gets over the inclined surface 121f, the extra force pushes the movable part 12 excessively. However, the pushed-in movable part 12 hits the partition part 14 and becomes a stopper, and it is possible to prevent the movable part 12 from being bent more than necessary. Thereby, the durability of the movable part 12 is improved.

  In the structure of the clip part 10 described above, even if it is attempted to pull up only the movable part 12 in a state where the movable part 12 is closed, the clip part 10 is not easily detached by a firm engagement. On the other hand, by slightly curving the base portion 11, the engaging portion LK expands and the movable portion 12 can be easily opened.

  That is, when the movable portion 12 is closed with the seat belt SB attached thereto, the movable portion 12 is securely fixed, and even if the head portion 20 is pulled as a handle, it does not come off or shift. On the other hand, in an emergency or the like, the movable portion 12 can be easily opened by slightly curving the base portion 11, and the seat belt drawer 1 can be easily detached from the seat belt SB.

(Structure of the inner part)
FIG. 4 is an exploded perspective view illustrating the structure of the inner portion.
The inner part 220 has a structure in which a spherical body is divided into two. That is, the inner portion 220 is formed into a spherical body by combining the first hemispherical portion 220R and the second hemispherical portion 220L. The inner part 220 has a hollow structure. Thereby, the weight of the head part 20 does not need to be increased more than necessary.

  Further, the overall weight balance of the seat belt drawer 1 is set according to the hollow size of the inner portion 220. That is, the overall weight balance of the seat belt drawer 1 varies depending on the number and size of the hammer portions 21 attached to the head portion 20. For this reason, when the head part 20 is desired to be heavy, the hollow area of the inner part 220 is reduced, and when the head part 20 is desired to be lighter, the hollow area of the inner part 220 is increased. In this way, the overall weight balance of the seat belt drawer 1 is set.

  Each of the first hemisphere portion 220R and the second hemisphere portion 220L is provided with a hole 220h. The shaft 21a of the hammer portion 21 is fitted into the hole 220h. Since the shaft 21a is tapered, the shaft 21a can be reliably fitted into the hole 220h.

  Since the hammer portion 21 is attached to the inner portion 220 constituting the spherical body in this way, the reaction force when the hammer portion 21 is hit against the glass can be received by the spherical body. The spherical body can efficiently disperse the force received compared with the case where the hammer portion 21 is received by the plate-like support member, and can withstand a large reaction force. Therefore, the reaction force transmitted from the hammer portion 21 can be reliably supported by the inner portion 220 even if the hammer is strongly struck, and the glass can be reliably broken by giving the strike force firmly.

(Example of use)
Next, an example of use of the seat belt puller 1 according to the present embodiment will be described.
FIG. 5 is a schematic diagram showing an example of mounting the vehicle on a seat belt.
First, the structure of the seat belt SB will be described. One end of the seat belt SB is wound around a retractor 50 provided inside the center pillar CP. The other end of the seat belt SB pulled out from the retractor 50 passes through a through ring 51 provided on the upper side of the center pillar CP and is folded downward, and passes through a routing 52 to a floor (not shown) next to the seat ST. It is fixed.

  The thruing 52 is provided with a metal fitting so as to engage with a buckle 53 fixed to the floor on the opposite side of the seat ring 51 from the through ring 51. The occupant sitting on the seat ST pulls out the seat belt SB and hangs diagonally from the shoulder, and fits the slutting 52 into the buckle 53. Thus, the portion of the seat belt SB on the side of the through ring 51 from the sluffing 52 is obliquely hung from the shoulder of the occupant to the vicinity of the waist on the opposite side, and the portion of the seat belt SB on the fixed end side from the sluffing 52 is around the occupant's waist. It will be multiplied.

  Next, attachment of the seat belt drawer 1 according to the present embodiment will be described. The seat belt puller 1 is mounted in the vicinity of the sluting 52 of the seat belt SB. To attach the seat belt drawer 1 to the seat belt SB, the movable portion 12 of the clip portion 10 is opened in advance, and the seat belt SB is inserted into the hole 10 h of the clip portion 10 from the gap between the movable portion 12 and the hook portion 13. Pass through. At this time, the head portion 20 is set to face the front of the vehicle.

  Next, the movable portion 12 is closed with the seat belt SB passed through the hole 10h. Accordingly, the seat belt SB is sandwiched between the movable portion 12 and the base portion 11, and the seat belt SB is firmly secured by the first convex portion 12a, the second convex portion 12b, and the third convex portion 11a of the movable portion 12. And can be fixed so as to bite.

FIGS. 6A and 6B are schematic views showing an example of use of the seat belt puller according to the present embodiment.
As shown in FIG. 6A, when the occupant sitting on the seat ST pulls out the seat belt SB, the occupant grasps the head portion 20 of the seat belt pulling tool 1 mounted in the vicinity of the sluting 52 in advance and pulls it out. .

  Since the head part 20 is a moderately sized spherical body, the head part 20 is easily gripped so as to be wrapped in the palm. Further, since the outer portion 210 of the head portion 20 is a soft material, the touch when it is gripped is also gentle. Since the head portion 20 is attached to the tip of the neck portion 30, the head portion 20 protrudes forward from the thruing 52. For this reason, the passenger | crew can grasp the head part 20 easily, without twisting a body. For example, when the seat belt SB is on the right side of the seat ST, the occupant can easily grasp the head portion 20 of the seat belt pulling tool 1 by bringing the right hand to the shoulder opening.

  Then, the occupant can pull out the sluting 52 together with the seat belt SB by pulling the gripped head portion 20 toward the front. Since the seat belt drawer 1 is firmly fixed to the seat belt SB by the clip portion 10, even if the seat belt drawer 1 is pulled out strongly, the seat belt drawer 1 does not come off or slip out of the seat belt SB. The belt SB can be pulled out.

  In particular, in the present embodiment, since the partition portion 14 is disposed between the engagement portion LK and the seat belt SB, when the seat belt pull-out tool 1 pulls out the seat belt SB, the engagement portion LK is removed from the seat belt SB. Even if a force is applied in the direction, the partition portion 14 can prevent the force from being transmitted to the engaging portion LK. For this reason, it can prevent effectively that the movable part 12 opens with the force at the time of pulling out seatbelt SB.

  After the seat belt SB is pulled out, as shown in FIG. 6B, the seat belt SB is slanted from the shoulder, and the sluting 52 is inserted into the buckle 53 and fixed. As a result, the seat belt SB is hung from the occupant's shoulders to the waist and around the waist, and the mounting of the seat belt SB is completed.

  In the state where the seat belt SB is mounted, the seat belt pulling tool 1 attached in the vicinity of the sluting 52 is disposed in the vicinity of the buckle 53. That is, since the seat belt drawer 1 is disposed near the occupant's waist, the occupant can also obtain a massage effect by grasping the head portion 20. In order to enhance the massage effect, the head portion 20 may be provided with appropriate protrusions.

  When using as a hammer, first, the movable part 12 of the clip part 10 is opened. To open the movable portion 12, as shown in FIGS. 3A and 3B, when a force is applied to slightly warp the base portion 11, the engaging portion LK expands, and the claw 121 of the movable portion 12 The movable part 12 opens over the claw 131 of the hook part 13. After the movable part 12 is opened, the seat belt SB is extracted from the gap between the movable part 12 and the hook part 13. As a result, the seat belt drawer 1 is removed from the seat belt SB.

FIG. 7 is a schematic diagram showing an example of use as a hammer.
After the seat belt puller 1 is removed from the seat belt SB, the cap 21c (see FIG. 1A) placed on the hammer portion 21 is removed to expose the hammer portion 21. Then, as shown in FIG. 7, the clip portion 10 of the seat belt puller 1 is gripped as a handle, and the tip of the hammer portion 21 is beaten toward the glass WD. Thereby, the glass WD can be broken and escape from the vehicle.

  Since the seat belt pulling tool 1 is attached to the seat belt SB, it can be used by immediately picking it up and searching for it when it is desired to use it as an emergency hammer. Further, when the seat belt SB is worn, the seat belt pulling tool 1 is in the vicinity of the buckle 53, so that even a passenger sitting in the adjacent seat or the rear seat can easily reach the hand. Moreover, since the seat belt SB can be easily detached from the seat belt SB by releasing the clip portion 10, even a passenger other than the passenger wearing the seat belt SB to which the seat belt drawer 1 is attached can be removed and used as a hammer. .

  In the present embodiment, the seat belt puller 1 can be removed from the seat belt SB and used as a hammer, so that the seat belt SB does not get in the way when swinging down toward the glass WD. In addition, the glass WD can be smashed without being limited to the range in which the seat belt SB extends, with a place where the seat belt SB can be easily struck and a posture that is easy to swing down.

  As described above, according to the seat belt pulling tool 1 according to the present embodiment, it can be normally used as a handle for pulling out the seat belt SB while being firmly fixed to the seat belt SB, and can be quickly removed from the seat belt SB in an emergency. Can be used as a glass split hammer.

  Although the present embodiment has been described above, the present invention is not limited to these examples. For example, although the spherical body is taken as an example of the head portion 20, a shape other than the spherical body may be used. Moreover, what added the addition, deletion, and design change of the component suitably with respect to the above-mentioned embodiment is also contained in the scope of the present invention as long as the gist of the present invention is included.

  As described above, the present invention can be suitably used for seat belts for passenger cars, large-sized automobiles such as buses and trucks, and seat belts for airplanes.
