(Operation of this embodiment)
As shown in FIG. 1, the posture of the seat back 104 is changed by rotating the seat back 104 from the forward-turned state (the state indicated by the two-dot chain line in FIG. 1) to the vehicle rear side. At this time, the engaged portion 73 of the striker wire 70 enters the groove portion 32A of the lock unit 20 and engages with the wire engaging portion 24A of the hook member 24 (see FIG. 2).

  As a result, the seat back 104 is locked (locked) to the vehicle body 200. By operating an operation portion (not shown) of the lock unit 20, the lock is released (the engaged portion 73 comes out of the wire engaging portion 24 </ b> A), and the seat back 104 can be rotated forward of the vehicle.

  Here, the hook member 24 may be displaced with respect to the engaged portion 73 in the direction B (see FIG. 2) perpendicular to the moving direction A of the hook member 24 along the attachment surface 202. The positional deviation of the hook member 24 with respect to the engaged portion 73 is caused by, for example, a dimensional error or an attachment error of each component in the seat back 104, the lock unit 20, and the striker 50.

  For example, as shown in FIG. 9A, when the lock unit 20 (hook member 24) is displaced downward, the engaged portion 73 entering the groove 32A is located above the guide portion 23. Hit the edge of the. As a result, the striker 50 moves in an arc shape in the counterclockwise direction in FIG. 9A, and the engaged portion 73 moves to the hook member 24 while the positional deviation of the hook member 24 with respect to the engaged portion 73 is eliminated. Guided. Then, the engaged portion 73 engages with the wire engaging portion 24 </ b> A of the hook member 24.

  At this time, as shown in FIG. 9B, the rubber member 80 of the striker 50 is elastically deformed so that the slit 84 is crushed and the slit 83 is expanded. The striker body 60 is biased to a predetermined position (initial position) by the elastic force generated by the elastic deformation of the rubber member 80. When the seat back 104 is turned to the vehicle front side and the engagement between the engaged portion 73 and the wire engaging portion 24A is released, the striker main body 60 returns to a predetermined position (initial position).

  Note that Z1 in FIG. 9A indicates the amount of displacement of the hook member 24 with respect to the engaged portion 73 (design position).

  Further, for example, as shown in FIG. 10A, when the lock unit 20 (hook member 24) is displaced upward, the engaged portion 73 that enters the groove 32A is Hit the lower edge. As a result, the striker 50 moves in a circular arc shape in the clockwise direction in FIG. 10A, and the engaged portion 73 is guided to the hook member 24 while the positional deviation of the hook member 24 with respect to the engaged portion 73 is eliminated. Is done. Then, the engaged portion 73 engages with the wire engaging portion 24 </ b> A of the hook member 24.

  At this time, as shown in FIG. 10B, the rubber member 80 of the striker 50 is elastically deformed so that the slit 83 is crushed and the slit 84 is widened. The striker body 60 is biased to a predetermined position (initial position) by the elastic force generated by the elastic deformation of the rubber member 80. When the seat back 104 is turned to the vehicle front side and the engagement between the engaged portion 73 and the wire engaging portion 24A is released, the striker main body 60 returns to a predetermined position (initial position).

  Note that Z2 in FIG. 10A indicates the amount of displacement of the hook member 24 with respect to the engaged portion 73 (design position).

  As described above, even when the hook member 24 is displaced with respect to the engaged portion 73, the wire engaging portion 24A of the hook member 24 can be engaged with the engaged portion 73 of the striker wire 70.

  Moreover, in this embodiment, since the lock unit 20 provided in the seat back 104 moves the striker body 60 side of the striker 50, the number of parts of the lock unit 20 does not increase and the lock unit 20 does not increase in size.

  Therefore, according to the configuration of the present embodiment, the hook member 24 that is displaced with respect to the engaged portion 73 along the mounting surface 202 is engaged with the engaged portion 73 without increasing the size of the lock unit 20. be able to.

  Further, in the configuration of the present embodiment, the striker body 60 moves in an arc along the mounting surface 202. For this reason, compared with the case where the whole striker main body 60 moves linearly along the attachment surface 202, the movement range becomes smaller, and the movement space of the striker main body 60 can be reduced.

  Further, as the striker main body 60 moves along the mounting surface 202, the striker is maintained while the engaged portion 73 remains orthogonal to the mounting surface 202, as shown by the two-dot chain line in FIG. The wire 70 moves. For this reason, as shown by a two-dot chain line in FIG. 13, it is suppressed that the engaged portion 73 is engaged with the wire engaging portion 24 </ b> A of the hook member 24 in a state where the engaged portion 73 is inclined obliquely. Therefore, poor engagement between the wire engaging portion 24A and the engaged portion 73, which is caused by the inclined portion 73 being inclined, is suppressed.

  Further, in the configuration of the present embodiment, the movement range of the striker body 60 is limited by the long hole 58. For this reason, the load input to the rubber member 80 can be adjusted. Therefore, the rubber member 80 can be prevented from being deformed beyond the elastic range.

  Further, in the configuration of the present embodiment, the rubber member 80 is attached to the attachment surface 202 together with the striker body 60 by the bolts 90 and 91 while being accommodated in the box-like striker body 60. For this reason, compared with the case where the rubber member 80 is attached to the attachment surface 202 separately from the striker body 60, or the case where the striker body 60 is attached to the attachment surface 202 after the rubber member 80 is attached to the striker body 60, the attachment work. Workability is improved.

  In the configuration of the present embodiment, as shown in FIG. 11, the rotation center R (rotation shaft 110) of the seat back 104 and the engaged point P (engaged point) of the engaged portion 73 are connected. The line L1 and the line L2 that connects the movement center C (bolt 91) of the striker body 60 and the engaged point P are orthogonal to each other when viewed in the seat width direction.

  The line L1 corresponds to the orthogonal direction B (see FIG. 2) in which the hook member 24 is displaced, and the striker body 60 (the engaged portion 73) moves along the line L1 (see M2). For this reason, the positional deviation of the hook member 24 with respect to the engaged portion 73 can be effectively eliminated. In FIG. 11, N <b> 1 indicates a position shift range of the hook member 24, and N <b> 2 indicates a movement range of the engaged portion 73.

  That is, as shown in FIG. 14, the striker body 60 is connected to a line L1 connecting the rotation center R (rotation shaft 110) of the seat back 104 and the engaged point P (engaged point) of the engaged portion 73. In a case where the line L2 connecting the movement center C (bolt 91) and the engaged point P is not orthogonal in the sheet width direction view (comparative example), the direction in which the hook member 24 is displaced (line L1) The engaged portion 73) moves so as to intersect the direction (line L1) (see M2). In FIG. 14, N <b> 1 indicates a position shift range of the hook member 24, and N <b> 2 indicates a movement range of the engaged portion 73.

(Modification)
In the above embodiment, the striker 50 is attached to, for example, the attachment surface 202 on the left side of the vehicle interior in the vehicle body 200, but is not limited thereto. For example, the vehicle body 200 may be attached to the attachment surface on the right side in the vehicle interior. In this case, for example, the aforementioned horizontal line portion 74 of the striker wire 70 is a portion to which the wire engaging portion 24A of the hook member 24 is engaged.

  In the above embodiment, the striker body 60 is configured to move in an arc shape around the bolt 91, but is not limited thereto. For example, it may be configured to move in an arc shape around the bolt 90. In this case, the long hole 58 and the circular hole 59 in the striker body 60 are changed to a circular hole and a long hole, respectively, and a slit 83, respectively, on the vehicle front side and the vehicle rear side with respect to the circular hole 89 of the rubber member 80 84 is formed. Furthermore, the striker body 60 may be configured to slide in the up-down direction or the vehicle front-rear direction.

  In the embodiment described above, the slits 83 and 84 are formed on the vehicle front side and the vehicle rear side with respect to the circular hole 81, but the present invention is not limited thereto. For example, the rubber member 80 may have a reduced thickness on each of the vehicle front side and the vehicle rear side with respect to the circular hole 81. That is, it is sufficient that the rubber member 80 is configured to be elastically deformable.

  In the above embodiment, the lock unit 20 is provided in the seat back 104 as a movable part of the vehicle seat 100, but is not limited thereto. For example, the seat cushion 102 may be used as the movable part provided with the lock unit 20.

  The present invention is not limited to the above embodiment, and various modifications, changes, and improvements can be made. For example, the modification examples described above may be appropriately combined.
