Description

  The present invention relates to a tongue plate fixing structure for a vehicle seat belt suitable for use in a central seat of a vehicle.

  In recent years, from the viewpoint of improving the safety of passengers in a rear seat (second seat or third seat) of a vehicle, a central seat (center seat) of the rear seat is also equipped with a three-point seat belt. In the case of such a three-point seat belt in the rear center seat, it is not possible to have a structure in which the webbing (strap) of the seat belt is directly fed out from the pillar portion on the side portion of the passenger compartment as in the case of the side seat. Therefore, in the case of the three-point seat belt in the center seat, a structure is used in which the webbing is extended from the back of the seat back or the ceiling of the passenger compartment.

  In general, a three-point seat belt is equipped with a movable tongue plate in the middle of one webbing whose base end is wound around a retractor, and an occupant seated in the seat grips the tongue plate. While pulling out the webbing from the retractor, it is used by locking it to the buckle installed at the rear end of the seat cushion of the seat. In this state of use, the webbing is divided into a lap strap (waist belt) and a webbing strap (diagonal belt) with the tongue plate as a boundary.

  In the case of a side seat, the tip of the webbing is locked to a pillar or the like, but in the case of the center seat, a tongue plate is also provided on the tip of the webbing, and when using the seat belt, this tip tongue plate is attached to the seat side. Used by locking to the buckle equipped with. When the seat belt is not used, the base end side of the webbing is wound around the retractor, and the tongue plate at the distal end is fixed to the ceiling portion in the vehicle compartment together with the movable tongue plate at the intermediate portion. Thereby, the webbing and the tongue plate do not hinder getting on and off.

Thus, in the case of the seat belt of the central seat, when the two tongue plates of the first tongue plate at the tip of the webbing and the movable second tongue plate are provided in the middle part of the webbing and the seat belt is not used. Therefore, it is necessary to fix the two tongue plates so as not to fall on the ceiling portion in the passenger compartment.
Therefore, it is important how the two tongue plates are locked so as not to fall on the ceiling portion in the vehicle interior, and various techniques relating to this have been developed.

  For example, in Patent Document 1, the tip of the first tongue plate is placed on the holding member that is installed on the ceiling and accommodates and holds the first and second tongue plates. The retracting direction of the retractor is opposite to the winding direction (reverse to the winding direction). A first holding hole that is detachably inserted along the direction), and a second holding hole that is detachably inserted along the retracting direction of the retractor along the retracting direction of the retractor. A configuration has been proposed in which the first holding hole is formed with an elastic projection that is close to and opposed to the receiving portion of the lower edge of the holding hole (paragraphs 0016 to 0018, 0022).

  According to such a configuration, a force in the pulling direction acts on the first tongue plate stored along the anti-winding direction of the seat belt by the winding bias by the retractor, but the front end portion of the first tongue plate However, it is securely held between the bent projection and the receiving portion by the restoring force of the projection, and a high holding effect is exhibited against the force in the pulling direction by the retractor (paragraph 0025).

  Further, Patent Document 2 includes a storage member that is installed on the ceiling and stores the first and second tongue plates. The storage member opens in the webbing winding direction and holds the first tongue plate. A holding portion and a second holding portion that opens in a direction opposite to the webbing winding direction and holds the second tongue plate are provided, and the second tongue plate has a webbing winding direction in the second tongue plate. In a state where the webbing is oriented and the webbing on the tip side of the second tongue plate faces the webbing pull-out direction, a configuration is proposed in which a sliding prevention means is provided to prevent the second tongue plate from sliding on the webbing ( Paragraphs 0018, 0020).

The sliding prevention means is provided on the second tongue plate, and the other side surface of the insertion port is narrowed at the edge of the one side surface facing the front and back surfaces of the webbing in the insertion port through which the webbing is inserted. It is comprised by the protrusion part formed so that it may protrude toward (paragraph 0018).
According to such a configuration, when the two tongue plates are housed, the sliding preventing means prevents the second tongue plate from sliding with respect to the webbing. Therefore, the retractor retracting force (tensile force) acting on the webbing. Acts on the second tongue plate in the direction of fitting into the second holding portion. Thereby, the second tongue plate is securely held by the second holding portion (paragraph 0022).

  Further, even if the webbing passed through the insertion port of the second tongue plate receives the winding force of the retractor, the webbing of the webbing on the tip side of the second tongue plate is prevented from sliding by the protruding portion. The length of the webbing is not changed, and the shape of the webbing is maintained by its bending strength, so that the first tongue plate is prevented from coming off from the first holding part, and the first tongue plate is securely attached to the first holding part. (Paragraph 0022).

JP 2009-23622 A Japanese Patent No. 4288611

  As in the techniques of Patent Documents 1 and 2 described above, when the first and second tongue plates are stored, the front end portion of the first tongue plate is along the retracting direction of the retractor (the direction opposite to the winding direction). The first holding part is detachably inserted into the first holding part, and the leading end of the second tongue plate is detachably inserted into the second holding hole along the retracting direction of the retractor. In addition, the storage position of the first and second tongue plates can be easily placed horizontally and horizontally, so that the storage structure of the ceiling portion can be suppressed in the height direction.

However, since the technique of Patent Document 1 is a configuration in which an elastic protrusion is formed in the first holding hole, the shape of the holding hole becomes complicated, resulting in an increase in manufacturing cost and without considering the durability of the protrusion. must not.
In addition, since the webbing passed through the insertion port of the second tongue plate is prevented from sliding at the insertion port, the technique of Patent Document 2 is caused by the sliding at the insertion port of the webbing. The tongue plate can be prevented from coming off from the first holding portion, but the first tongue plate can be securely held by the first holding portion only by changing the length of the webbing on the tip side of the second tongue plate. There may be cases where this is not possible. In this respect, it is necessary to restrain the first tongue plate to the first holding portion by some means.

  The present invention has been devised in view of such a problem, and is provided with tongue plates at the front end of the webbing and the intermediate part of the webbing, and stores the two tongue plates in the ceiling portion of the vehicle interior. An object of the present invention is to provide a tongue plate fixing structure for a vehicle seat belt, which allows the both tongue plates to be securely held on the ceiling portion with good operability.

  In order to achieve the above object, a tongue plate fixing structure for a vehicle seat belt according to the present invention includes a retractor mounted on a vehicle, a webbing wound around a base end portion of the retractor, and a distal end portion of the webbing A first tongue plate mounted on the webbing, a second tongue plate movably mounted on an intermediate portion of the webbing and having a floating hole through which the webbing freely moves, and a ceiling portion of the vehicle, the retractor to the ceiling A tongue plate fixing structure for a vehicle seat belt, comprising: a holding member that guides the webbing that is fed into a passenger compartment below the unit and holds the two tongue plates in a storage state; And a first insertion hole extending along the ceiling surface of the ceiling portion and into which the first tongue portion of the first tongue plate is inserted. A wall portion and a second wall portion having a second insertion hole into which the second tongue portion of the second tongue plate is inserted are opposed to each other, and a recess for storing both the tongue plates; A slit that is formed adjacent to the second wall portion and in which the webbing floats inside is provided, and the first tongue plate is directed in a counter biasing direction opposite to a biasing direction by the retractor. The first tongue portion is inserted into the first insertion hole and housed, and the second tongue plate is inserted into the second insertion hole in the biasing direction. When the tongue plate is housed and the tongue plate is in the retracted state where the first tongue portion is inserted into the first insertion hole and the second tongue portion is inserted into the second insertion hole, the second tongue plate is The base of the tongue plate (this Part of the loop portion of the webbing loop coupled to including) a separate component, is characterized in that it is configured to abut toward vertically upward and the counter biasing direction.

The recess is formed with a partial recess for receiving a portion of the first tongue plate in the storage state in which the first tongue portion is inserted into the first insertion hole. In the storage state of the two tongue plates, It is preferable that the two tongue plates are in contact with the base portion of the first tongue plate so as to press the part against the partial recess.
Further, the second tongue plate, the floating hole, and the webbing at the time of storage are arranged so that the urging force of the retractor is directed in the urging direction and vertically upward when the second tongue plate is stored. It is preferable.

  According to the tongue plate fixing structure for a vehicle seat belt of the present invention, the first tongue plate is inserted into the first insertion hole with the first tongue portion facing in the opposite biasing direction to the biasing direction of the retractor. Since the second tongue plate is inserted and stored in the second insertion hole with the second tongue portion facing the retracting direction of the retractor, the detachable operability in the stored state is good. Since the storage positions of the first and second tongue plates can be easily arranged horizontally and horizontally, the storage structure of the ceiling portion can be suppressed in the height direction.

  On the other hand, when the first tongue portion of the first tongue plate is inserted into the first insertion hole in the counter-biasing direction, the urging force of the retractor acts to remove the first tongue portion from the first insertion hole. When the tongue plate is housed, the second tongue plate is configured to contact the base portion of the first tongue plate vertically upward and in the counter-biasing direction, so that the first insertion hole of the first tongue plate The withdrawal from the is prevented.

  In addition, a partial recess is formed in the recess to receive a portion of the first tongue plate in the storage state in which the first tongue portion is inserted into the first insertion hole. In the storage state of both tongue plates, the second tongue plate is If the base part of the first tongue plate is abutted and a part of the first tongue plate is pressed against the partial recess, a part of the first tongue plate is held in the partial recess, and from the first insertion hole of the first tongue plate. Detachment is more reliably prevented, and vibration of the first tongue plate during vehicle travel is suppressed.

  Furthermore, when the retracting force of the retractor is set so that the retracting force of the retractor is directed vertically upward, the retracting force of the retractor ensures that the retracted state of the retracting state of the 2nd tongue plate is maintained. Thus, the first tongue plate can be more reliably prevented from detaching from the first insertion hole, and vibrations of the first and second tongue plates during vehicle travel can be suppressed.

The slit 255 is disposed adjacent to the wall portion 258 and on the other end side in the longitudinal direction from the wall portion 258.

  When the seat belt 20 is not used, the first tongue 232 of the first tongue plate 23 is properly inserted into the first insertion hole 259a and the second tongue 242 of the second tongue plate 24 is second. In this state, the second tongue plate 24 (here, the end 246 of the second tongue plate 24) is inserted into the first tongue plate 23. The base portion 235 is set so as to abut in a predetermined direction.

  Here, “appropriately inserted” means that the tongue portions 232 and 242 are inserted into the insertion holes 259a and 258a to the deepest portion or the vicinity of the deepest portion. Further, when the first tongue portion 232 of the first tongue plate 23 is properly inserted into the insertion hole 259a, the first tongue portion 232 is counter-biased in a direction opposite to the biasing force that the webbing 21 receives from the biasing force applying mechanism. When the second tongue 242 of the second tongue plate 24 is properly inserted into the insertion hole 258a in the direction along the urging direction (substantially leftward in FIG. 4), the webbing 21 is attached to the second tongue 242. The peripheral wall surfaces of the insertion holes 259a and 258a are formed so as to face in a direction along a biasing direction (substantially rightward in FIG. 4) that receives a biasing force from the force applying mechanism.

The “predetermined direction” when the end 246 of the second tongue plate 24 abuts the base 235 of the first tongue plate 23 is a component vertically upward (upward in FIG. 4) and the webbing 21. The direction which has the component of the counter biasing direction which is opposite to the biasing force which the 2nd tongue plate 24 receives from the biasing force provision mechanism of the retractor 22 via this.

Here, the second tongue plate 24 is in direct contact with a part of the loop part 21 a at its end 246, and a part of the loop part 21 a that is in direct contact with this end 246 is used as the base of the first tongue plate 23. 235.

  The contact of the end 246 of the second tongue plate 24 is to restrain the first tongue plate 23 from moving in the direction opposite to the predetermined direction by restraining the first tongue plate 23 in the predetermined direction. is there. Therefore, when another regulation is made with respect to the contact of the end 246 of the second tongue plate 24, “the second tongue plate 24 restrains the first tongue plate 23 in the predetermined direction. ”Or a part of the loop portion 21 a of the webbing 21 that is locked to the first tongue plate 23”.

  Further, in the present embodiment, the recess 256 has a portion of the first tongue plate 23 (here, the first tongue plate 23 is located in a retracted position where the first tongue portion 232 is inserted into the first insertion hole 259a). Then, a partial recess 257 is formed to accommodate the one side of the loop portion 21a. When the two tongue plates 23 and 24 are accommodated, the second tongue plate 24 is placed on the base 235 of the first tongue plate. A part of the plate 23 abuts against the partial recess 257.

  In other words, the partial recess 257 and a part of the first tongue plate 23 accommodated in the partial recess 257 are located where the end 246 of the second tongue plate 24 abuts on the base 235 of the first tongue plate 23. Since the second tongue plate 24 is positioned in a substantially predetermined direction, that is, vertically upward and in the counter-biasing direction, the second tongue plate 24 presses a part of the first tongue plate 23 against the partial recess 257 by contact with the first tongue plate 23. Works.

  In such a state that the tongue plate is housed, the first tongue portion 232 of the first tongue plate 23 is properly inserted into the first insertion hole 259a, and the second tongue portion 242 of the second tongue plate 24 is second inserted. When properly inserted into the hole 258a, the second tongue plate 24 applies the urging force in the urging direction from the urging force applying mechanism of the retractor 22 via the webbing 21 while being in contact with the first tang plate 23. receive. This urging direction is from the arrangement of the second tongue plate 24, the floating hole 245, and the webbing 21 at the time of storage to the insertion direction of the second tongue portion 242 of the second tongue plate 24 into the second insertion hole 258a. The urging force prevents the second tongue plate 24 from being detached from the second insertion hole 258a of the second tongue portion 242.

(Action, effect)
Since the tongue plate fixing structure of the vehicle seat belt according to the embodiment of the present invention is configured as described above, the following effects can be obtained.
First, the first tongue plate 23 is inserted and accommodated in the first insertion hole 259a with the first tongue portion 232 facing in the opposite biasing direction to the biasing direction of the retractor 22, and the second tongue plate 24 is The second tongue portion 242 is inserted and accommodated in the second insertion hole 258a so that the urging direction of the retractor 22 is biased. For example, the first tongue plate 23 and the second tongue plate 24 are held together, The second tongue plate 24 can be inserted into the second insertion hole 258a while inserting the first tongue plate 23 into the first insertion hole 259a.

In addition, since the storage positions of the first and second tongue plates 23 and 24 are easily arranged horizontally and horizontally, the storage structure of the ceiling portion 4 can be suppressed in the height direction.
When the first tongue portion 232 of the first tongue plate 23 is inserted into the first insertion hole 258a in the counter-biasing direction, the urging force of the retractor 22 causes the first tongue portion 232 to move from the first insertion hole 258a. However, in this tongue plate storage state, the end 246 of the second tongue plate 24 abuts the base 235 of the first tongue plate 23 vertically upward and in the counter-biasing direction. The detachment of the 1 tongue plate 23 from the first insertion hole 258a is prevented.

  In the present embodiment, the recess 256 is formed with a partial recess 257 that accommodates a part of the first tongue plate 232 in the accommodated state in which the first tongue 232 is inserted into the first insertion hole 259a. 23, 24, the second tongue plate 24 abuts against the base 235 of the first tongue plate 23 and presses a portion of the first tongue plate 23 against the partial recess 257, so that a portion of the first tongue plate 23 is partially recessed. 257, the detachment of the first tongue plate 23 from the first insertion hole 259a is more reliably prevented, and the vibration of the first tongue plate 23 during traveling of the vehicle is also suppressed.

  Further, when the second tongue plate 24 is stored, the second tongue portion 242 is inserted into the second insertion hole 258a so as to face the urging direction of the retractor 22 and vertically upward, and the urging force of the retractor 22 is inserted into the second tongue portion 242. Since the direction of insertion into the second insertion hole 258a is directed to the second insertion hole 258a, the urging force of the retractor 22 reliably holds the second tongue plate 24 in the retracted state, so that the first tongue plate 23 can be removed from the first insertion hole 259a. Detachment is more reliably prevented, and vibrations of the first and second tongue plates 23 and 24 during vehicle travel are suppressed.
