Description

  The present invention relates to a seat belt apparatus for restraining an occupant sitting on a seat of a vehicle such as an automobile with a seat belt without using a tongue, and engages and holds the seat belt when the seat belt is mounted. The present invention also relates to a technical field of a seat belt device provided with the same.

  For example, a seat belt device mounted on a vehicle such as an automobile restrains the occupant's inertial movement by restraining the occupant with the seat belt when a large deceleration is applied to the vehicle, such as when the vehicle collides. Conventionally, as one of such seat belt devices, for example, a seat belt device mounted on a vehicle such as an automobile restrains the inertial movement of an occupant when a large deceleration is applied to the vehicle at the time of a vehicle collision or the like. To do. Conventionally, there is a three-point seat belt device as one of such seat belt devices (see, for example, Patent Document 1).

  In general, the three-point seat belt device including the seat belt device described in Patent Document 1 includes a tongue that is slidably supported by the seat belt. In such a three-point seat belt device, an occupant seated in a vehicle seat grips the tongue and pulls out the seat belt from the seat belt retractor, and engages the tongue with a buckle fixed to the vehicle body such as a vehicle seat. The occupant is restrained by the seat belt. In that case, like the seat belt device described in Patent Document 1, a seat belt device provided with a tongue is normally held at a position where the tongue can be easily removed by a tongue stopper attached to the seat belt when the seat belt is not attached. It has come to be. In addition, in the seat belt device described in Patent Document 1, a finger hook portion is provided on at least one of the tongue and the tongue stopper in order to facilitate the operation of pulling out the seat belt.

  However, the seat belt device having such a tongue has the following problems. That is, in the seat belt device including the tongue and the tongue stopper, the weight of the tongue is applied to the seat belt through the tongue stopper. In addition, the tongue is composed of at least a strength member using metal in order to firmly support the seat belt that restrains the occupant. For this reason, the weight of the tongue is relatively large. Therefore, it is necessary to increase the belt winding force of the seat belt retractor.

  As described above, when the belt retracting force of the seat belt retractor is large, the pulling force of the seat belt from the seat belt retractor is large when the seat belt is mounted, and the occupant can smoothly handle each seat belt and tongue. Is difficult. In addition, since the belt winding force is increased, passenger comfort is reduced when the belt is worn.

  Further, sliding resistance is generated between the tongue and the seat belt during the seat belt mounting operation, and it is necessary to insert the engaging piece of the tongue into the hole of the buckle and engage with the buckle. For this reason, it becomes more difficult to smoothly handle each seat belt and tongue by the occupant. Furthermore, when the tongue is disengaged from the buckle to release the seat belt, the tongue may collide with a vehicle body such as a door.

Therefore, a tongueless seat belt device that restrains an occupant with a seat belt without using a tongue has been proposed (see, for example, Patent Documents 2 and 3). In the seat belt devices described in these Patent Documents 2 and 3, the seat belt pulled out from the seat belt retractor is engaged and held by a seat belt engagement holding device fixed to the vehicle body side such as a vehicle seat, It is divided into a shoulder side belt and a lap side belt to restrain the passenger.
Since such a tongueless seat belt device does not include a tongue, the above-described problems caused by the tongue are solved or suppressed.

A pair of rectangular guide grooves 26a and 26b extending in the vertical direction are formed on the left and right side surfaces of the arm support member 26, respectively. On the other hand, a pair of rectangular guide ridges 10g and 10h are formed on the left and right side walls of the long groove 10f formed in the vertical direction on the rear end surface in the vehicle longitudinal direction of the vertical wall 10a of the base 10, respectively. The arm support member 26 is accommodated in the long groove 10f, and a pair of guide grooves 26a and 26b are slidably fitted and supported by the corresponding guide protrusions 10g and 10h, respectively. Accordingly, the arm support member 26 is guided in the long groove 10f by the guide protrusions 10g and 10h so as to be vertically movable.

An arm support shaft 26 c is erected on the arm side surface of the arm support member 26. The arm support shaft 26c is formed in a stepped on a large diameter shaft 26c ₁ of the cylindrical large-diameter shaft 26c ₁ Toko concentric cylindrical small diameter shaft 26c ₂ Prefecture. An elongated notch groove 26c ₃ extending in the axial direction is formed on the outer peripheral surface of the small diameter shaft 26c ₂ . The notched groove 26c _3, the engaging claw 24a of the arm rotation control pawl 24 is in engageable. That is, the arm rotation control pawl 24 by the pawl biasing spring 25 is always biased in a direction to engage the grooves 26c ₃ notched its engaging claw 24a.

  Between the arm 12 and the arm support member 26, there is provided an arm urging means that constantly urges the arm 12 clockwise in FIGS. 3B and 6A. As shown in FIGS. 6A and 7, the arm biasing means is constituted by a coiled torsion spring 27.

Arm 12, during assembly of the arm supporting member 26 and the torsion spring 27, together with the coil portion 27a of the torsion spring 27 is fitted respectively into the recess 12e of the large-diameter shaft 26c ₁ and the arm 12 of the arm support shaft 26c, the arm support shaft diameter shaft 26c ₂ of 26c is supported lifting the bearing portion 12b ₁ of the cover 12b through the through hole 12d of the arm 12, the arm 12 is rotatably supported by an arm support shaft 26c. At this time, one end 27b of the torsion spring 27 is fitted and supported in a spring support hole 26d formed in the arm support member 26, and the other end 27c of the torsion spring 27 is fitted and supported in the longitudinal groove 12g. Then, as described above, the arm 12 is constantly urged clockwise by the torsion spring force of the torsion spring 27.

Then, by engaging the groove 26c ₃ notches engaging claw 24a of the arm rotation control pawl 24, arm 12 clockwise rotation is prevented. In addition, by leaving the groove 26c ₃ notches engaging claw 24a of the arm rotation control pawl 24, the arm 12 is possible in the clockwise rotation. FIG. 3 (a), engages when the seat belt operation device 8 illustrated in (b) is in the retracted position C, the groove 26c ₃ notches engaging claw 24a of the arm rotation control pawl 24, and FIG. 2 when the seat belt operation device 8 shown in in belt engaging operation position D is arranged to leave from the groove 26c ₃ notches engaging claw 24a of the arm rotation control pawl 24.

  Between the bottom of the long groove 10f of the base 10 and the lower surface of the arm support member 26, an arm support member urging spring 28 that urges the arm support member 26 upward is provided in a contracted manner. When the belt hanger 11 is unlatched by the urging force of the arm supporting member urging spring 28, the arm supporting member 26, the arm 12 and the belt hanger 11 move upward integrally.

As shown in FIG. 6A, a pawl actuating means 10i for actuating the arm rotation control pawl 24 is provided on the upper part of the rear end surface of the base 10 in the longitudinal direction of the vehicle. The pawl operating means 10i is formed from a substantially arc-shaped protrusion. When the arm support member 26, the arm 12 and the belt hanger 11 are integrally moved upward, the pressed portion 24c of the arm rotation control pawl 24 protruding to the base 10 side is connected to the lower end 10i ₁ of the pawl operating means 10i. It comes to contact. After the pressed portion 24c and the pawl actuating means 10i come into contact with each other, the arm support member 26, the arm 12 and the belt hanger 11 are further moved up, so that the arm rotation control pawl 24 is rotated around the rotation shaft 12h. Thus, the locking claw 24a is disengaged from the groove 26c ₃ notches, the arm 12 and the belt hanger 11 can rotate clockwise in FIGS. 6 (a) around the large diameter shaft 26c ₁ by the biasing force of the torsion spring 27 It becomes a state.

As the arm rotation control pawl 24 in a further upper movement of the arm 12 is rotated a predetermined amount, so that the pressed portion 24c is disengaged from the lower end 10i ₁ of the pawl actuating means 10i, the arms 12 and the belt hanger 11 is rotated clockwise . At this time, while the pressed portion 24c is guided to the outer peripheral side surface 10i ₂ of the pawl actuating means 10i, so that the arm 12 rotates. The arm 12 abuts against an arcuate stopper 10j provided at the rear end of the base 10 in the front-rear direction of the vehicle, thereby preventing the arm 12 from rotating further clockwise and positioning the arm 12 at this rotational position. Is done. At this rotational position of the arm 12, the belt hanger 11 is set to the belt engagement operation position D shown in FIG.

8A and 8B show an example of an embodiment of a seatbelt operating tool according to the present invention, in which FIG. 8A is a perspective view and FIG. 8B is a partially enlarged cross-sectional view taken along line VIIIB-VIIIB in FIG.
As shown in FIG. 8A, the seatbelt operating tool 8 of this example has a main body 8a (corresponding to a support portion of the present invention) formed in a substantially isosceles triangle shape. The seat belt operating tool 8 is merely used for pulling out the seat belt 3, and does not receive a large load applied to the seat belt 3 due to inertial movement of the occupant during an emergency of the vehicle. Therefore, the seatbelt operating tool 8 does not need to be composed of a strength member, and is formed of a flat and thin lightweight material such as a resin or a lightweight metal. As a result, the weight of the seatbelt operating tool 8 is reduced, which is 1/8 to 1/4 of the weight of the conventional known tongue. Further, since the weight of the seat belt operating tool 8 is reduced, the stopper 9 can also be formed of a lightweight material. Thus, since the weights of the seat belt operating tool 8 and the stopper 9 are small, the load applied to the seat belt 3 by the seat belt operating tool 8 and the stopper 9 is also reduced.

  A string (strap) -shaped operation member 8c (corresponding to the operation unit of the present invention) is integrally attached to the substantially isosceles triangular top 8b of the main body 8a. The operation member 8c is soft, easy to bend and elongated, and both end portions thereof are fixed to the top portion 8b to form a loop shape. In that case, the operation member 8c is formed from a lightweight material such as cloth, leather, light metal, or resin in the form of a thread, a band, or a chain. When the operation member 8c is operated, the occupant 4 pulls the operation member 8c by placing his / her finger on the loop shape portion of the operation member 8c or holding the operation member 8c by hand. .

  The main body 8a is provided with an elongated belt insertion hole 8d through which the seat belt 3 is slidably inserted. When the seat belt 3 is pulled out by operating the seat belt operating tool 8, the seat belt 3 extending from the belt guide anchor 5 is bent (or curved) at the insertion portion of the belt insertion hole 8, and the belt anchor 3a. It is designed to extend toward. That is, a portion of the seat belt operating tool 8 on the side opposite to the operation member 8c side with respect to the belt insertion hole 8d is a belt drawing portion 8e (corresponding to a belt bending portion of the present invention). The belt withdrawing portion 8e is adapted to be pulled out from the seat belt retractor 2 while bending the seat belt 3 in a V shape in the direction of the belt guide anchor 5 and the direction of the belt anchor 3a.

  The width of the belt insertion hole 8d in the direction orthogonal to the longitudinal direction is preferably set to be larger than the thickness of the seat belt 3 and 1.5 times or less the thickness of the seat belt 3. Thus, the seat belt 3 is prevented from being twisted when the seat belt 3 is pulled out by operating the seat belt operating tool 8. Further, the operating member 8c of the seat belt operating tool 8 is attached so as to be positioned on the vehicle compartment side (that is, on the passenger side) when the seat belt 3 is not attached. Therefore, the seat belt 3 can be hung on the belt hanger 11 without being twisted.

  The belt insertion hole 8d is formed in a curved and elongated shape whose central portion in the longitudinal direction is convex on the side opposite to the operation member 8c side. The shape of the belt insertion hole 8d does not need to be the entire belt insertion hole 8d, and the edge 8f of the belt lead-out portion 8e forming the belt insertion hole 8d is opposite to the operation member 8c side in the longitudinal center. Any curved shape that is convex can be used. By setting the shape of the belt insertion hole 8d in this way, the bent portion 3b of the seat belt 3 abuts the belt withdrawing portion 8e at both side edges in the width direction, and the belt withdrawing portion 8e at the center in the width direction. Even if it comes into contact with or touches, it will only lightly hit. Accordingly, the sliding resistance between the seat belt 3 and the belt withdrawing portion 8e is reduced, and the seat belt operating tool 8 slides more smoothly with respect to the seat belt 3 when the seat belt operating tool 8 is pulled. become.

As shown in FIG. 8 (b), the belt withdrawal unit 8e comprises a tapered surface in which the surface 8g of the belt guide anchor 5 side from the edge 8f is recessed inward in the belt withdrawing unit 8e relative to the surface 8a ₁ of the main body 8a together are surface 8h of the belt anchor 3a side is a tapered surface that is recessed to the inside of the belt withdrawal unit 8e relative to the rear surface 8a ₂ of the main body 8a from its edge 8f. The two tapered surfaces 8g and 8h of the belt lead-out portion 8e are formed to be inclined with each other at a predetermined angle θ (°). This angle θ (°) is determined by the opening angle formed between the seat belt 3c on the belt guide anchor 5 side of the seat belt 3 and the seat belt 3d on the belt anchor 3a side so that the seat belt 3 is smoothly and easily hung on the belt hanger 11. The size is set according to the size (particularly, thickness) of the belt hanger 11 of the seatbelt engagement / holding device 7 so as to be a large size.

  Specifically, the distance from the bent portion 3b of the seat belt 3 to the one side of the seat belt 3 (in the illustrated example, the seat belt 3d) is approximately 30 mm in the direction perpendicular to the one side of the seat belt 3. Is preferably set to 45 ° or more so that the other side seat belt 3 (seat belt 3c in the illustrated example) is located at a position of about 30 mm or more. By setting the angle θ (°) to 45 ° or more, the seat belts 3 on both sides can be smoothly and easily hung on the belt hanger 11 of the engagement holder 7 of a size estimated to be normally used. Be able to.

Also, the left and right end portions 8i ₁ and 8i ₂ of the main body 8a in the vicinity of both end portions in the longitudinal direction of the belt insertion hole 8d are formed in a curved shape. Thereby, when the seatbelt operating tool 8 collides with the interior member of the vehicle body, damage to the interior member is prevented.

  The belt insertion hole 8d can be formed in an elongated shape curved in the opposite direction to the above example. In this case, the bent portion 3b of the seat belt 3 abuts on the belt withdrawing portion 8e at the center in the width direction, and abuts against the belt withdrawing portion 8e at both ends in the width direction or only lightly touches even if abutting. The sliding resistance between the belt drawing portion 8e and the seat belt 3 is reduced. The belt insertion hole 8d can also be formed in a straight line. In this case, the sliding resistance between the belt drawing portion 8e and the seat belt 3 is slightly larger than that of the curved belt insertion hole 8d.

Next, the operation of belt mounting and belt mounting release of the seat belt device 1 of the first example configured as described above will be described.
When the belt is not worn (when the belt is not used), the seat belt 3 is wound around the seat belt retractor 2, and the seat between the belt anchor 3a and the belt guide anchor 5 as shown by a two-dot chain line in FIG. The belt 3 is substantially linear. At this time, the seatbelt operating tool 8 is held by the stopper 9 at a position where the occupant 4 seated on the vehicle seat 6 can easily grasp it by hand (position indicated by a two-dot chain line in FIG. 1). The belt hanger 11 is latched by the two pawls 13 and 14 at the latch position A, held in the storage position C by the base 10 shown in FIGS. 3A and 3B, and substantially in the vertical direction. It has become.

Furthermore, the engaging claw 24a of the arm rotation control pawl 24 as shown in FIG. 9 (I) (a) is engaged with the groove 26c ₃ notch arm support shaft 26c. At this time, as shown in FIGS. 9 (II) and 9 (a), the pressed portion 24c of the arm rotation control pawl 24 is in an initial position on one end side of the guide hole 12i of the arm 12.

In this state, the occupant first presses the release button 22 in order to sit on the vehicle seat 6 and attach the seat belt 3. Thereby, both pawls 13 and 14 rotate clockwise in FIG. 4A, and the locking claws 13a and 14a of both pawls 13 and 14 move upward and to the right. Then, the arm supporting member 26, the arm 12 and the belt hanger 11 are guided by the guide protrusions 10g and 10h by the urging force of the arm supporting member urging spring 28 and moved upward according to the upward movement of the locking claws 13a and 14a. Moving. At this time, since the state in which the locking claw 24a is engaged with the groove 26c ₃ notches is maintained, the arms 12 and the belt hanger 11 does not rotate.

  As the pawls 13 and 14 rotate, the pressed portions 13b and 14b of both pawls 13 and 14 approach the belt hanger 11 side, but the pressing portion 11u of the belt hanger 11 moves upward, so the pressed portion 13b. When entering the moving area of the belt hanger 11, it does not interfere with the pressing portion 11u.

When the straight line α is positioned above the center 15a of the pawl rotating shaft 15, both pawls 13 and 14 rotate toward the non-latching position B by the urging force of the tension spring 17 regardless of the pressing force of the belt hanger 11 upward. Then, the self-latching is released by contacting and stopping the second stopper portion 10e. As a result, both the locking claws 13a, 14a completely escape from the moving region of the seat belt operating tool 8, and the arm support member 26, the arm 12, and the belt hanger 11 are moved up without being obstructed by both the pawls 13, 14. At this time, the pawls 13 and 14 are held at the non-latching position B in contact with the second stopper portion 10 e of the base 10 by the urging force of the tension spring 17. In a further upper movement of the arm 12, the pressed portion 24c as shown in FIG. 9 (I) (b) contacts the lower end 10i ₁ of the pawl actuating means 10i. Until this time, as shown in FIGS. 9 (II) and 9 (b), the pressed portion 24c is maintained at the initial position on one end side of the guide hole 12i.

When the arm 12 is further moved upward after the pressed portion 24c comes into contact with the pawl operating means 10i, the arm rotation control pawl 24 rotates clockwise in FIGS. 9 (I) and 9 (b) about the rotation shaft 12h (FIG. 9 ( II) Starts rotating counterclockwise in (b). The rotation of the arm rotation control pawl 24 is disengaged from the FIG. 9 (I) the locking claw 24a is notched groove 26c _3, as shown in (c). At this time, as shown in FIGS. 9 (II) and 9 (c), the pressed portion 24c is guided by the guide hole 12i and moves from the initial position.

Be disengaged from the engaging claw 24a is notched groove 26c _3, while the pressed portion 24c is in contact with the lower end 10i ₁ of the pawl actuating means 10i includes an arm 12 which is urged by the torsion spring 27 is rotated do not do. If the pressed portion 24c is disengaged from the lower end 10i ₁ of the pawl actuating means 10i, rotates clockwise in FIG. 9 (I) (c) by the biasing force of the spring 27 the arm 12 is torsion. At this time, the pressed portion 24c is guided to the outer peripheral side surface 10i ₂ of the pawl actuating means 10i. Further, when the pressed portion 24c is out of the lower end 10i ₁ of the pawl actuating means 10i, the upward movement of the arm supporting member 26 is stopped. Thereby, the notch groove 26c ₃ is held at a position where the locking claw 24a can be engaged. When the arm 12 comes into contact with the stopper 10j as shown in FIGS. 9I and 9D, the rotation of the arm 12 is prevented and the belt hanger 11 is set to the belt engagement operation position D shown in FIG. At the belt engagement operation position D of the belt hanger 11, the belt hanger 11 is inclined substantially in the direction of the belt guide anchor 5 as described above, and is set to a position where the occupant 4 can easily hang the seat belt 3. Further, at the belt engagement operation position D of the belt hanger 11, the vehicle front side of the belt hanger 11 is opened.

  Next, the passenger hangs his / her finger on the loop shape portion of the operating member 8c of the seat belt operating tool 8 or grips the operating member 8c by hand, and the operating member 8c is moved toward the seat belt engagement holding device 7. Pull to. Thereby, the seat belt 3 is pulled out from the seat belt retractor 2. Then, as shown in FIG. 10A, the seat belt 3 is placed so that the belt hanger 11 is positioned between the seat belts 3 on both sides of the bent portion 3b of the seat belt 3 formed by the operation member 8c. The belt hanger 11 is fitted and hung from the front side of the vehicle. At this time, since the angle θ (°) of the belt withdrawing portion 8e of the seat belt operating tool 8 is set as described above, the seat belt 3 can be smoothly and easily hung on the belt hanger 11. In addition, since the belt hanger 11 is substantially directed toward the belt guide anchor 5 and is set at a position where the seat belt 3 can be easily hung, the seat belt 3 can be hung even more easily. Thus, the seat belt 3 is engaged with a predetermined position of the belt hanger 11.

Next, the passenger pushes the belt hanger 11 downward by hand. Then, the arm 12 is rotated counterclockwise in FIGS. 9I and 9D by the downward pressing force by the occupant on the belt hanger 11. Therefore, the belt hanger 11 also rotates in the same direction. As the belt hanger 11 rotates, the seat belt 3 hung on the belt hanger 11 is further pulled out. If the pressed portion 24c is disengaged from the outer peripheral side surface 10i ₂ of the pawl actuating means 10i, the arm rotation control pawl 24 rotates counterclockwise in FIG. 9 (I) (c) by the biasing force of the pawl biasing spring 25. Since the notch groove 26c ₃ is held at a position where the locking claw 24a can be engaged, as shown in FIGS. 9I and 9B, the locking claw 24a of the arm rotation control pawl 24 is notched. Engage with ₃ . As a result, the arm 12 becomes non-rotatable, and the belt hanger 11 is substantially vertically oriented as shown in FIG.

  By further downward pressing of the belt hanger 11 by the occupant, the arm support member 26, the arm 12, and the belt hanger 11 are moved downward against the biasing force of the arm support member biasing spring 28. By the downward movement of the belt hanger 11, the seat belt 3 hung on the belt hanger 11 is further pulled out.

  After the belt hanger 11 is moved downwardly, the pressing portion 11u of the belt hanger 11 comes into contact with the pressed portion 13a of the pawl 13, and then the belt hanger 11 is further moved downward so that both pawls 13 and 14 are moved as shown in FIG. Rotate counterclockwise at. When both the pawls 13 and 14 are rotated and the straight line α is positioned below the center 15 a of the pawl rotating shaft 15, the two pawls 13 and 14 are urged by the tension spring 17 regardless of the downward pressing force of the belt hanger 11. Then, it rotates toward the latch position A and comes into contact with the first stopper portion 10d to stop, thereby self-latching. Thereafter, when the occupant releases his hand from the belt hanger 11, the belt hanger 11 is released and slightly lifted by the urging force of the arm support member urging spring 28 to come into contact with the locking claws 13a and 14a. ), (B) and FIG. 10 (c), the storage position C is latched with the seat belt 3 engaged and held. At this time, the release button 22 slightly protrudes from the base 10. Further, by releasing the belt hanger 11, the extra-drawn seat belt 3 is taken up by the seat belt retractor 2 to remove the slack of the seat belt 3, and the seat belt 3 fits the occupant 4 with a small force. To do.

  As a result, the seat belt 3 is attached to the occupant 4 and the seat belt 3 on the belt guide anchor 5 side is used as a shoulder belt with the lower end of the belt hanger 11 (that is, the bent portion of the seat belt 3) as a boundary. In addition, the upper body such as the chest can be restrained, and the lower body such as the waist of the occupant 4 can be restrained by the seat belt 3 on the belt anchor 3a side from the lower end of the belt hanger 11 as a lap belt. Therefore, in the event of an emergency in which a deceleration greater than the deceleration during normal travel is applied to the vehicle, the seat belt retractor 2 prevents the seat bell 3 from being pulled out as in the conventional three-point seat belt device. As a result, the occupant 4 trying to move inertial is restrained by the seat belt 3. At this time, the seat belt 3 is pushed forward by the inertial force of the occupant and tries to move, but the forward movement of the seat belt 3 is prevented by the steps 11a, 11f, 11k and the locking claws 10m. 3 does not come off the belt hanger 11. And the big force from the seatbelt 3 is firmly supported by these level | step difference 11a, 11f, 11k and the latching claw 10m.

When the occupant presses the release button 22 to release the seat belt, the belt hanger 11 is set from the storage position C to the belt engagement operation position D as described above. The occupant removes the seat belt 3 from the belt hanger 11 by operating the seat belt operating tool 8 as described above. Thereafter, the occupant releases the seat belt operating tool 8 so that the seat belt 3 is wound around the seat belt retractor 2, and the seat belt 3 and the seat belt operating tool 8 are not attached to each other in the non-attached position (not shown) shown in FIG. Use position).
Then, the occupant again presses the belt hanger 11 downward to latch the belt hanger 11 in the storage position C as described above.

  According to the seat belt engagement holding device 7 of this example, the belt hanger 11 is set to the belt engagement operation position D when the belt hanger 11 engages and holds the seat belt 3 for belt attachment. Thereby, since the belt hanger 11 comes to be located in the passenger | crew 4 side, the passenger | crew 4 can hang the seatbelt 3 on the belt hanger 11 smoothly and easily. Thereby, the handleability of the seatbelt 3 at the time of belt mounting operation can be improved.

  In particular, by setting the belt engagement operation position D to a position higher than the storage position C, it is possible to set the belt engagement operation position D to a height position at which the occupant 4 can easily perform the belt-engaging operation of the seat belt 3. Accordingly, the occupant 4 can hang the seat belt 3 on the belt hanger 11 more smoothly and more easily, and the handleability of the seat belt 3 can be further improved. On the other hand, in the storage position C where the belt hanger 11 is latched, the belt hanger 11 can be made lower than the belt engagement operation position D. Thereby, it is possible to suppress the belt hanger 11 from interfering with various actions in the passenger compartment of the occupant such as a speed change operation or a car audio operation when the belt is attached.

  Further, the seat belt 3 can be mounted more easily by setting the storage position C by simply pressing the belt hanger 11 downward from the belt engagement operation position D. Furthermore, by forming the belt hanger 11 in a substantially flat plate shape having a predetermined width in a direction orthogonal to the vehicle front-rear direction, the seat belt 3 can be more firmly engaged and held on the belt hanger 11.

  Further, by tilting the substantially flat belt hanger 11 so that the upper end of the belt hanger 11 approaches the occupant 4 side at the belt engagement operation position D, the occupant 4 makes the seat belt 3 more smoothly and more smoothly. The belt hanger 11 can be hung more easily. Thereby, the handleability of the seatbelt 3 at the time of belt mounting operation can further be improved.

  Furthermore, by setting the substantially flat belt hanger 11 to be substantially vertically at the storage position C, the belt hanger 11 at the storage position C can be moved in the vehicle left-right direction even if the belt hanger 11 is formed in a flat plate shape. Can be prevented from protruding greatly. Thereby, the installation space of the vehicle left-right direction of the belt hanger 11 can be made small.

  Furthermore, the width of the front side of the belt hanger 11 in the vehicle front-rear direction is set to be smaller than the width of the rear side, and the seat belt 3 is moved from the front side to the rear side in the vehicle front-rear direction to be hung on the belt hanger 11; Further, by moving the seat belt 3 from the rear side to the front side in the vehicle front-rear direction and detaching it from the belt hanger 11, the belt hooking operation and the belt hooking operation of the seat belt 3 to the belt hanger 11 can be performed more smoothly and This can be performed more easily.

FIG. 11 is an exploded perspective view partially showing a seat belt engagement holding device used in the seat belt device in the second example of the embodiment of the present invention. In the following description, components corresponding to those in the previous example are assigned the same reference numerals, and detailed description thereof is omitted.

The stepped recess 33 includes a large recess 33a having a large width and a small recess 33b having a width smaller than that of the recess 33a.

The second base member 10 ₂ when mounted to the first base member 10 _1, the flange 31a of the drive gear 31 in the vertical direction in the longitudinal groove formed by a substantially concave portion 33a is accommodated. The drive gear 31 moves up and down while being guided by the long groove. Also, as shown in FIGS. 12A and 12B, rack teeth 34 extending in the vertical direction are formed on one side surface of the narrow recess 33b. The drive gear 31 is engaged with the rack 34, and the drive gear 31 is rotated by the rotational drive force of the electric motor 29, so that the electric motor 29, the rotary shaft 30, and the drive gear 31 move up and down integrally. It becomes like this.

  The rotating shaft 30 passes through the long hole 32 so as to be rotatable and protrudes to the outside of the base 10. The protruding rotary shaft 30 further passes through the through hole 12d of the arm body 12a. Thereby, the arm main body 12a is supported by the rotating shaft 30 so that relative rotation is possible. And the edge part of the rotating shaft 30 is rotatably supported by the bearing part 12b1 of the cover 12b. A locking gear 35 is attached to the rotating shaft 30 protruding from the through hole 12d so as to be rotatable integrally with the rotating shaft 30. The locking claw 24a of the arm rotation control pawl 24 can be locked to the teeth 35a of the locking gear 35.

Next, the operation of belt attachment and belt attachment release of the seat belt device 1 of the second example configured as described above will be described.
When the seat belt 3 is not worn (when not in use), the belt hanger 11 is latched at the storage position C as in the first example. Then, when the occupant 4 presses the release button 22, both pawls 13 and 14 are set to the non-latching position B as in the first example. Further, the electronic control unit detects the pressing operation of the release button 22 and rotates the electric motor 29 in the clockwise direction in FIGS. 14 (I) and 14 (a). Thereby, since the latching claw 24a is not latched to the latching gear 35, the drive gear 31 and the latching gear 35 rotate in the same direction via the rotating shaft 30.

Then, due to the engagement of the drive gear 31 and the rack teeth 34, as shown in FIGS. 14 (I), (II) (a), the belt hanger 11, the arm 12, the electric motor 29, the drive gear 31 and the locking gear 35 are provided. Move up together. If the pressed portion 24c of the rotation control pawl 24 is located at the upper end 10i ₃ of the pawl actuating means 10i, the rotation control pawl 24 locking claw 24a starts rotating in the direction to approach the locking gear 35, to. 14 (I), (II) (b), the locking claw 24a is locked to one of the teeth 35a of the locking gear 35, and the rotational driving force of the electric motor 29 is rotated. 30, is transmitted to the arm 12 via the locking gear 35 and the rotation control pawl 24, and the arm 12 moves upward while rotating clockwise in FIGS. 14 (I) and 14 (b). Thereby, the pressed portion 24c of the rotation control pawl 24 is separated from the upper end 10i ₃ of the pawl actuating means 10i.

When the arm 12 rotates a predetermined amount, the electronic control unit detects this and stops the rotation of the electric motor 29, and holds the rotation stop of the electric motor 29, thereby holding the arm 12 at the rotation position. That is, as shown in FIGS. 14 (I), (II) and (c), the belt hanger 11

To drive). As a result, the arm 12 and the belt hanger 11 move downward while rotating in the same direction.

If the pressed portion 24c of the rotation control pawl 24 abuts the upper end 10i ₃ of the pawl actuating means 10i, then the rotation control pawl 24 locking claw 24a starts rotating in a direction away from the locking gear 35. At this time, since the upper end 10i ₃ is inclined as described above, the rotation of the rotation control pawl 24 is smoothly started. Thereafter, the pressed portion 24c moves to the outer surface 10i ₂ of the pawl actuating means 10i, the engagement between the engagement claw 24a and the engagement gear 35 is released, the rotation of the arm 12 is stopped. Further, the rotation of the electric motor 29 causes the belt hanger 11, the arm 12, the electric motor 29, the drive gear 31, and the locking gear 35 to move down integrally. When the belt hanger 11 is latched by both pawls 13 and 14, the electronic control unit detects this and stops the rotation of the electric motor 29. As a result, the belt hanger 11 is set to the storage position C, and the seat belt 3 is attached to the occupant 4.

  The release button 22 is pushed to release the seat belt 3. Then, as described above, the electronic control unit drives the electric motor 29 to rotate, and sets the belt hanger 11 to the belt engagement operation position D. Then, as in the first example described above, the occupant 4 operates the seat belt operating tool 8 to remove the seat belt 3 from the belt hanger 11. Thereafter, when the occupant 4 releases the seat belt operating tool 8, the seat belt 3 is wound around the seat belt retractor 2. Further, when the occupant pushes the belt hanger 11 downward, the belt hanger 11 is stored and held in the storage position C in the same manner as described above.

  According to the seat belt device 1 of the second example, the setting of the storage position C and the belt engagement operation position D of the belt hanger 11 is performed by the electric motor 29, so that the seat belt mountability can be further improved. it can. Other functions and effects of the seat belt device 1 of the second example are the same as those of the first example.

FIG. 15 is an exploded perspective view partially showing a seat belt engagement holding device used in the seat belt device in the third example of the embodiment of the present invention, and FIG. 16A is a partial assembly of the third example. FIG.
As shown in FIGS. 15 and 16 (a), the seatbelt engagement holding device 7 used in the seatbelt device 1 of the third example is the rear end surface in the vehicle front-rear direction of the vertical wall 10a of the L-shaped base 10.

Further, a pawl actuating means 10i is provided on the rear end surface of the up-down direction wall 10a in the longitudinal direction of the vehicle. The pawl actuating means 10i is formed in an L-shaped cross section and is elongated in the up-down direction. Vehicle part in the longitudinal direction rear end surface parallel to the pawl actuating means 10i vertical wall 10a is a pawl rotation regulating portion 10i _4.
The arm support member 26 is formed in an L shape, and a horizontal hole 26 e of the arm support member 26 is provided with a guide hole 26 f through which the guide shaft 36 is slidable, and a male screw shaft 37. Is provided with a female screw hole 26g through which the screw is rotatably threaded.

  Further, a through hole 26 i is formed in the upper and lower walls 26 h of the arm support member 26, and the support shaft 42 is passed through the through hole 26 i. Then, the through-hole 12d of the arm 12 is passed through the support shaft 42 penetrating the through-hole 26i, so that the arm 12 is supported by the arm support member 26 so as to rotate clockwise in FIGS. 15 and 16A. Has been. A torsion spring 27 is provided between the arm 12 and the arm support member 26. In that case, the coil portion 27a of the torsion spring 27 is fitted to the support shaft 42, respectively. At this time, one end 27b of the torsion spring 27 is fitted and supported in a spring support hole 26d formed in the arm support member 26, and the other end 27c of the torsion spring 27 is fitted and supported in the longitudinal groove 12g. Then, as described above, the arm 12 is constantly urged clockwise by the torsion spring force of the torsion spring 27.

An arm rotation control groove 12j is provided at the end of the arm 12 opposite to the belt hanger 11 mounting side. As shown in FIG. 16 (a), the arm rotation control groove 12j is fitted vertically movably in the pawl rotation regulating portion 10i ₄ of the pawl actuating means 10i. In this case, as shown in FIG. 17A (shown by a solid line in FIG. 16A), the arm rotation control groove 12j is fitted into the pawl rotation restricting portion 10i ₄ at the storage position C of the belt hanger 11.

Then, while the whole of the arm rotation control groove 12j is fitted into the pawl rotation restricting portion 10i _4, the arms 12 are held the angle (posture) in the stowed position C be urged by the torsion spring 27.

Further, a part of the arm rotation control groove 12j is disengaged from the pawl rotation restricting portion 10i _4, arm 12 is rotatable clockwise in FIG. 17 (a) in biased since the torsion spring 27. In that case, as shown in FIG. 15 and FIG. 16 (a), the lower arm 12 of the arm rotation control groove 12j is provided with a rotation restricting portion 12k, and the arm 12 as shown in FIG. 17 (b). When the rotation restricting portion 12k comes into contact with the horizontal portion 26e of the arm support member 26 by this rotation, further rotation of the arm 12 is prevented. When the arm 12 is thus prevented from rotating, the belt hanger 11 is set to the belt engagement operation position D. The electric motor 29 of the third example is also driven and controlled by an electronic control device (not shown) as in the second example.
In the third example, the spring 28, the notch groove 26c ₃ and the stopper 10j are not provided. Other configurations of the seat belt device 1 of the third example and other configurations of the seat belt engagement holding device 7 are the same as those of the first example.

Next, the operation of belt attachment and belt attachment release of the seat belt device 1 of the third example configured as described above will be described.
When the seat belt 3 is not worn (when not in use), the belt hanger 11 is latched at the storage position C as in the first example. When the occupant 4 presses the release button 22, the belt hanger 11 is unlatched as in the first example. Further, the electronic control unit detects the pressing operation of the release button 22 as in the second example, and rotates the electric motor 29 in the clockwise direction in FIGS. 15 and 16A. As a result, the male screw shaft 37 rotates counterclockwise. Then, the arm support member 26 moves up, and the arm 12 and the belt guide 11 also move up together. At this time, since the arm support member 26 is guided by the guide shaft 36, the arm support member 26 moves up smoothly without rotating.

When the upper end of the arm rotation control groove 12j comes to the upper end 10i ₃ of the pawl rotation regulating portion 10i _4, since a part of the subsequent arm rotation control groove 12j disengaged from the pawl rotation restricting portion 10i _4, the arms 12 and the belt hanger 11 The rotation starts in the clockwise direction as described above. When the rotation restricting portion 12k of the arm 12 contacts the arm support member 26, the rotation of the arm 12 is prevented and the belt hanger 11 is set to the belt engagement operation position D shown in FIG.

Similar to the first and second examples described above, the occupant 4 pulls out the seat belt 3 and places it on the belt guide 11, and then presses the belt guide 11 downward. The electronic control unit detects this in the same manner as in the second example described above, and drives the electric motor 29 to rotate in the direction opposite to that described above. Then, the male screw shaft 37 also rotates in the opposite direction to that described above, so that the belt hanger 11, the arm 12 and the arm support member 26 move downward integrally. Due to the downward movement of the arm support member 26, the upper end 10i ₃ of the pawl rotation restricting portion 10i ₄ comes into contact with the bottom of the arm rotation control groove 12j, and thereafter, the upper end 10i ₃ presses the bottom of the arm rotation control groove 12j. Thereby, the arm 12 rotates counterclockwise opposite to the above. When all of the arm rotation control groove 12j is fitted into the pawl rotation regulating portion 10i _4, the rotation of the arm 12 is prevented, the arm 12 is the angle (posture) and shown in FIG. 17 (a), this angle is maintained. At this time, the belt hanger 11 is in the vertical direction.

Thereafter, the belt hanger 11, the arm 12, and the arm support member 26 are integrally moved downward while the vertical posture of the belt hanger 11 is maintained. When the belt hanger 11 is latched to reach the storage position C, the electronic control unit detects this and stops the electric motor 29. Thus, the seat belt 3 is attached to the occupant 4 in the same manner as in the above examples.
Since the operation of releasing the seat belt 3 in the seat belt device 1 of the third example is the same as the operation when the seat belt 3 is mounted and the first and second examples, the description thereof is omitted. .
According to the seat belt device 1 of the third example, since the electric motor 29 is provided on the base 10 side and not provided on the arm support member 26, the weight of the moving members of the belt hanger 11, the arm 12, and the arm support member 26 is reduced. Can be reduced. Thereby, the rotational torque of the electric motor 29 can be reduced. Other functions and effects of the seat belt device 1 of the third example are substantially the same as those of the seat belt device 1 of the second example.
