The wire 32 is inserted into the guide groove 44, the proximal end portion of the wire 32 from the wire guide 36 is extended in the front-rear direction, and the distal end portion of the wire 32 is directed upward from the wire guide 36. It is extended in the direction toward the front side. In other words, the wire guide 36 has an extending direction on the buckle 34 side of the wire 32 (a tip side portion of the wire 32 than the wire guide 36) and a side opposite to the buckle 34 side of the wire 32 (based on the wire guide 36 of the wire 32). The angle between the stretching direction of the end side portion) is made acute. The left side of the guide groove 44 is closed by the left wall 24.

  Next, the operation of this embodiment will be described.

  In the lift-up buckle device 10 configured as described above, when the occupant does not sit on the seat 13 (when the seating sensor does not detect that the occupant is seated on the seat 13), as shown in FIG. The guide 36 is disposed at the rear part of the drive screw 20 and the rail 22, and the buckle 34 is disposed at the lower and rear storage position.

  When the occupant is seated on the seat 13 (when the seating sensor detects that the occupant is seated on the seat 13), the motor 14 is positively driven and the drive screw 20 rotates in one direction under the control of the control device. As a result, as shown in FIG. 3B, the wire guide 36 is moved to the front side while being guided by the guide hole 30 of the rail 22 on the guide shaft 42. For this reason, the relative movement of the wire 32 along the guide groove 44 causes the buckle 34 fixed to the tip of the wire 32 to move upward and to the front side and be placed at the raised position. Further, the webbing is pulled out from the winding device, and the webbing tongue is attached to the buckle 34. Further, since the tongue is attached to the buckle 34 disposed at the raised position, the tongue can be easily attached to the buckle 34.

  When the tongue is attached to the buckle 34 (when the buckle switch detects that the tongue is attached to the buckle 34), the motor 14 is reversely driven by the control of the control device, and the drive screw 20 is moved in the other direction. The wire guide 36 is moved to the rear side while being guided by the guide hole 30 of the rail 22 on the guide shaft 42. For this reason, when the wire 32 is relatively moved along the guide groove 44, the buckle 34 fixed to the tip of the wire 32 is moved to the lower side and the rear side and arranged at the storage position. Thereby, the tongue is moved to the lower side and the rear side together with the buckle 34, so that the webbing is attached to the occupant.

  Here, when the wire guide 36 moves, the wire 32 moves along the guide groove 44 of the wire guide 36 and the tip of the wire 32 and the buckle 34 move. That is, the distal end of the wire 32 and the buckle 34 can be moved without moving the proximal end of the wire 32. For this reason, the structure which moves the base end of the wire 32 can be made unnecessary, and the number of parts can be reduced.

  Further, the angle of the wire guide 36 with respect to the proximal end portion of the wire 32 at the distal end side of the wire 32 with respect to the proximal end portion of the wire 32 is set to an acute angle. For this reason, the amount of movement of the buckle 34 relative to the amount of movement of the wire guide 36 can be increased. In other words, the wire guide 36 operates in the same manner as a moving pulley, so that the amount of movement of the tip of the wire 32 and the buckle 34 relative to the amount of movement of the wire guide 36 in the front-rear direction (in the direction toward the front as it goes upward). (Moving amount along) can be increased. In other words, the amount of movement of the wire guide 36 can be reduced with respect to the amount of movement of the other end of the wire 32 and the buckle 34, so that the apparatus can be downsized.

  Furthermore, as shown in FIG. 4, the wire guide 36 moves to the front side, so that the tip of the wire 32 not only extends upward and forward, but also the tip side portion of the wire 32 from the wire guide 36 to the front side. Can be displaced. That is, in the configuration in which the distal end of the wire 32 is moved by moving the proximal end of the wire 32, the distal end of the wire 32 and the buckle 34 only move upward and forward (see the two-dot chain line in FIG. 4). Compared with the configuration, in the configuration of the present embodiment, the tip end of the wire 32 and the buckle 34 can be moved further forward. Thereby, a passenger | crew can mount | wear a tongue with the buckle 34 more easily.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above, and various modifications other than those described above can be implemented without departing from the spirit of the present invention. Of course.
