  FIG. 4 is a plan view showing a configuration and an attaching method of the seat lock device, which is a view as seen from an arrow A in FIG. 3. FIG. 5 is a cross-sectional view taken along line B-B ′ of FIG. 4. FIG. 6 is a plan view showing a state in which the striker is released from the seat lock device. FIG. 7 is a plan view showing the behavior of the seat lock device when the striker entry position is deviated. 6 and 7 are plan views corresponding to the A arrow view of FIG.

  The seat lock device 6 includes a case 10, a base plate 11, a hook 12, an open lever 13, a guide lever 14, and a hook shaft 15.

  The case 10 and the base plate 11 are housing members that house the hook 12, the open lever 13, the guide lever 14, and the like. The case 10 is provided with a striker entry groove 10A, a hook shaft insertion hole 10B, an open lever support shaft 10C, and a guide lever support shaft 10D. The striker entry groove 10A is a groove into which the striker 306 enters. The hook shaft insertion hole 10 </ b> B is a hole through which the hook shaft 15 that rotatably supports the hook 12 is inserted. The open lever support shaft 10 </ b> C is a cylindrical shaft that rotatably supports the open lever 13. The guide lever support shaft 10D is a cylindrical shaft that supports the guide lever 14 rotatably. The base plate 11 is provided with a striker entry groove (not shown) and a hook shaft insertion hole 11A.

  The hook 12 is rotatably supported by the hook shaft 15 inserted through the hook shaft insertion hole 10B of the case 10 and the hook shaft insertion hole 11A of the base plate 11, and is engaged with the striker 306 that has entered the striker entry groove 10A. It moves between a restraining position (position shown in FIG. 4) for restraining the striker 306 and a release position for releasing the restrained striker 306. When the hook 12 is in the restraining position, a hook portion (not shown) in the hook 12 crosses the striker entry groove 10 </ b> A, and the engaging surface 12 </ b> A engages with the striker 306 to restrain the striker 306. The hook 12 is urged in a direction (counterclockwise direction in FIG. 4) from the open position to the restraint position by a spring (not shown).

  The open lever 13 is a lever that moves the hook 12 from the restraint position to the release position, and is rotatably supported by the open lever shaft 10C. The open lever 13 is biased counterclockwise in FIG. 4 by a spring (not shown). When the hook 12 is in the restrained position, the open lever 13 is held at a position where the first engaging portion 13A is engaged with the indicator protrusion 12B of the hook 12.

  The guide lever 14 is a lever that holds the hook 12 moved to the release position at the release position, and is rotatably supported by the guide lever shaft 10D. The guide lever 14 is urged clockwise in FIG. 4 by a spring (not shown). When the hook 12 is in the restraining position, the guide lever 14 is held at a position retracted from the striker entry groove 10 </ b> A by the pressing load that the striker contact portion 14 </ b> A receives from the striker 306.

  The hook shaft 15 is provided with a flange 15A at one end of a cylindrical member that supports the hook 12, and is rotatably inserted into the hook shaft insertion hole 10B of the case 10 and the hook shaft insertion hole 11A of the base plate 11. The hook shaft 15 is also an attachment portion when attached to the attachment member 7. The seat lock device is configured by inserting the shaft 801 </ b> B of the bolt 801 into the hook shaft 15 and the through hole 7 </ b> B of the attachment member 7 and fastening and fixing with the nut 802. 6 is rotatably attached to the attachment member 7. At this time, a gap is provided between the base plate 11 and the mounting member 7 by interposing the flange 15 </ b> A of the hook shaft 15 between the base plate 11 and the mounting member 7.

  When releasing the striker 306 restrained by such a seat lock device 6, the open lever 13 is rotated in the clockwise direction in FIG. Thereby, the pressing portion 13B of the open lever 13 presses the indicator protrusion 12B of the hook 12, and the hook 12 rotates counterclockwise in FIG. Then, when the hook 12 rotates to the release position shown in FIG. 6 and the engagement between the engagement surface 12A of the hook 12 and the striker 306 is released, the striker 306 is released. When the striker 306 is released, the guide lever 14 rotates clockwise as shown in FIG. 6, and the striker contact portion 14A advances into the striker entry groove 10A. As a result, the released striker 306 is pushed out in a direction to exit from the striker entry groove 10A. When the guide lever 14 is moved to the position shown in FIG. 6, the hook locking portion 14B of the guide lever 14 is engaged with the engagement protrusion 12C of the hook 12, and the hook 12 is held in the released position. Thereafter, when the operation of rotating the open lever 13 in the clockwise direction in FIG. 4 is stopped, the open lever 13 rotates in the counterclockwise direction, and the second engaging portion 13C is indicated by the indicator of the hook 12 as shown in FIG. It is held at a position where it engages with the protrusion 12B.

  When the seat lock device 6 is in the state shown in FIG. 6, when the seat back 302 is moved to the support position and the striker 306 enters the striker entry groove 10 </ b> A, the striker 306 presses the striker contact portion 14 </ b> A of the guide lever 14. To do. As a result, the guide lever 14 rotates counterclockwise in FIG. 6, and the engagement between the hook locking portion 14B of the guide lever 14 and the engagement protrusion 12C of the hook 12 is released. Then, the hook 12 rotates in the clockwise direction in FIG. 6 and moves to the restraining position shown in FIG. At the same time, the guide lever 14 rotates counterclockwise in FIG. 6 and moves to the position shown in FIG.

  In the seat lock device 6 shown in FIGS. 4 to 6, the hook shaft 15 is rotatably provided on the case 10 and the base plate 11, and is attached to the attachment member 7 via the hook shaft 15. Therefore, the seat lock device 6 is attached to the attachment member 7 so as to be rotatable about the hook shaft 15 as a rotation shaft. Therefore, when the seat lock device 6 is attached to the attachment member 7 with a gap provided between the seat back support portion 5 </ b> A of the cross member 5, the seat lock device 6 can be rotated with respect to the attachment member 7. . At this time, if the flange 15 </ b> A of the hook shaft 15 is interposed between the base plate 11 and the mounting member 7, a gap is generated between them. Therefore, rotation failure due to friction between the base plate 11 (seat locking device 6) and the mounting member 7 can be prevented.

  When the seat lock device 6 is attached to the attachment member 7, the attachment position is determined so that the position in the vehicle left-right direction of the striker entry groove 10 </ b> A and the striker 306 matches as shown in FIG. 6. However, the entry position of the striker 306 with respect to the striker entry groove 10A may be shifted in the left-right direction of the vehicle due to the tolerance of the attachment positions of the seat lock device 6 and the striker 306. In view of this point, if the width of the entrance in the striker entry groove 10A is increased as in the seat lock device 6 shown in FIGS. 4 and 6, even if the entry position of the striker 306 is shifted in the vehicle left-right direction, The striker 306 is allowed to enter the striker entry groove 10A.

  Further, the seat lock device 6 of the present embodiment is attached to the attachment member 7 in a state where the seat lock device 6 is rotatable about the hook shaft 15 as a rotation shaft. Therefore, as shown in FIG. 7, when the approach position of the striker 306 is greatly deviated from the reference approach position P to the right side of the vehicle, the seat lock device 6 rotates. In FIG. 7, the position of the seat lock device 6 before the striker 306 enters the striker entry groove 10A is indicated by a two-dot chain line. When the striker 306 enters the striker entry groove 10A with the seat lock device 6 in the position indicated by the two-dot chain line in FIG. 7, the striker 306 enters the striker before reaching the innermost part of the striker entry groove 10A. It contacts the side surface of the groove 10A. Since the width of the striker entry groove 10A is gradually narrowed from the entrance to the innermost part, when the striker 306 comes into contact, the case 10 (the seat lock device 6) is pressed by the pressing load from the striker 306 as shown in FIG. Rotate counterclockwise at. Since the opening position of the striker entry groove 10A is changed by this rotation, the striker 306 can be moved to the innermost part of the striker entry groove 10A. Therefore, the striker 306 can press the striker abutting portion 14A of the guide lever 14, and the hook 12 can move to the restraining position to reliably restrain the striker 306. Thereby, the allowance for allowing the striker 306 to be restrained (meshing allowance) can be increased.

  Note that, when the engagement allowance is increased by rotating the seat lock device 6, as shown in FIG. 7, even when the seat lock device 6 is rotated within the range of the allowance allowance, the seat lock device 6 and the seat The seat lock device 6 is attached to the attachment member 7 so as to have a gap with the back support portion 5A.

  When the striker 306 provided on the seat back 302 is restrained by the seat lock device 6 having the above-described configuration, the seat back 302 is fixed at the position indicated by the solid line shown in FIG. In this state, when the luggage in the trunk room TR moves to the front side of the vehicle and comes into contact with the seat back 302, the seat back 302 is pressed to the front side of the vehicle. At this time, the striker 306 provided on the seat back 302 pulls the seat lock device 6 toward the front side of the vehicle, and a load F is applied to the seat lock device 6 as shown in FIG. The load F applied to the seat lock device 6 is first transmitted to the attachment member 7 via the fastening member 8 (bolt 801 and nut 802). At this time, the attachment member 7 undergoes bending deformation that moves the seat lock device 6 to the front side of the vehicle, but the seat lock device 6 and the opening forming surface in the seat back support portion 5 </ b> A of the cross member (plate-like member) 5. There is a gap between them. Therefore, when the load applied to the seat lock device 6 is small, the seat lock device 6 does not contact the seat back support portion 5A, and the load F applied to the seat lock device 6 is not transmitted to the seat back support portion 5A.

  When the load F applied to the seat lock device 6 is large and the bending deformation of the mounting member 7 is increased, the seat lock device 6 comes into contact with the seat back support portion 5A, and the load F applied to the seat lock device 6 is applied to the seat back support portion 5A. Is transmitted to. At this time, since the load F applied to the seat lock device 6 is transmitted to the attachment member 7 and the seat back support portion 5A, the load transmitted to the seat back support portion 5A causes the seat lock device 6 to be applied to the seat back support portion 5A. Smaller than when installed. That is, in the mounting structure of the seat lock device 6 according to the present embodiment, the load F applied to the seat lock device 6 can be released to two locations of the mounting member 7 and the seat back support portion 5A. For this reason, the strength against the load F applied to the seat lock device 6 is improved, and deformation of the cross member (plate member) 5 due to the seat lock device 6 being pulled can be prevented.

  In particular, the cross member 5 having the seat back support portion 5A is a reinforcing member provided in the left-right direction of the vehicle body 1 and has excellent strength. Therefore, even if the seat lock device 6 pulled by the striker 306 contacts the seat back support portion 5A, the seat back support portion 5A is not easily deformed. Therefore, changes in the positions and shapes of the openings 5B and 5C due to the deformation of the seat back support 5A can be prevented, and the striker 306 of the seat backs 302 and 304 can be reliably restrained by the seat lock device 6.

  As shown in FIG. 5, when the seat lock device 6 is attached to the attachment member 7 so that the axial center direction of the hook shaft 15 is orthogonal to the seat lock device attachment surface of the attachment portion 7A, the hook 12 is attached to the attachment portion. It rotates in a plane substantially parallel to the 7A seat lock device mounting surface. Therefore, the distance from the engagement surface 12A of the hook 12 that receives the load from the striker 306 to the seat lock device mounting surface of the mounting portion 7A can be shortened. As a result, the moment when the seat lock device 6 is pulled can be reduced, and the load on the seat lock device 6 can be reduced.

  Further, in the vicinity of the attachment portion 7A of the attachment member 7 to which the seat lock device 6 is attached, there is a corner portion where the seat back support portion 5A of the cross member 5 and the attachment member 7 are joined. This corner portion is excellent in strength because the two plate-like members overlap and become thick. For this reason, the strength against the load F applied to the seat lock device 6 is further improved.

  Further, the seat lock device mounting surface of the mounting portion 7A for mounting the seat lock device 6 is oriented in a direction orthogonal to the opening forming surface of the seat back support portion 5A, so that the seat lock device 6 is pulled when it is pulled. The seat lock device 6 can be reliably brought into contact with the seat back support portion 5 </ b> A by bending deformation of the member 7.

  Further, the striker 306 of the seat back 302 is provided at a position that is substantially in the center in the vehicle left-right direction between a pair of hinges 303 that are connected to the seat back 302 and the seat cushion 301. For this reason, when the seat back 302 is pressed to the front side of the vehicle while the striker 306 of the seat back 302 is restrained by the seat lock device 6, the position from the position restrained by the seat lock device 6 to each hinge 303. The distances in the left-right direction of the vehicle are substantially equal, and the seat back 302 is prevented from being twisted around the hinge 303. As a result, the seat lock device 6 pulled by the striker 306 comes into contact with the seat back support portion 5A substantially straight, thereby preventing a local load from being applied to the seat back support portion 5A.

  Further, when the seat lock device 6 is attached to the attachment member 7 with a gap provided between the seat lock device 6 and the seat back support portion 5A of the cross member 5, as shown in FIG. Can be changed to change the position of the striker entry groove 10A. Therefore, the allowance allowance of the striker 306 can be ensured without increasing the width of the inner portion of the striker entry groove 10A, and the seat lock device 6 can be downsized.

  Further, in the seat lock device mounting structure shown in FIGS. 1 and 3, the seat lock device 6 is directly mounted on the seat lock device mounting surface of the mounting portion 7 </ b> A of the mounting member 7. However, when attaching the seat lock device 6 to the attachment member 7, the seat lock device 6 may be attached to the attachment member 7 via a bracket without being limited thereto. Furthermore, instead of providing the attachment member 7 separate from the cross member 5 (seat back support portion 5A), an attachment portion for attaching the seat lock device 6 by bending the cross member 5 may be provided.

  In the seat lock device mounting structure according to the present invention, the load F applied to the seat lock device 6 via the striker 306 is defined as the seat back support portion 5A of the cross member 5 (particularly around the openings 5B and 5C). What is necessary is just to be able to escape to a different part. For this reason, the attachment portion for attaching the seat lock device 6 such as the attachment portion 7A of the attachment member 7 only needs to be at a position separated from the seat back support portion 5A, and the position, the orientation of the seat lock device attachment surface, and the like can be appropriately changed. Of course there is.

  In this embodiment, a vehicle having a trunk through function is cited, and a seat lock device mounting structure for holding a seat back that separates a trunk room and a room at a predetermined angle is shown. The mounting structure of the seat lock device is not limited to this, and can be applied to the case where the striker provided on the seat cushion is restrained by the seat lock device mounted on the floor surface of the vehicle body.
