The lock mechanism 20 is generally composed of a base member 22, a hook (not shown), a pole (not shown), a spring member (not shown), a mounting bolt 24, and a mounting nut (not shown). The base member 22 is a two-plate structure made of a metal plate-like member. The base member 22 is rotatably supported by sandwiching a hook (not shown) and a pole (not shown), and constitutes the seat back 12. A side portion of the frame 16 is fixedly installed via a first bracket 17. The hook (not shown) is a substantially U-shaped metal plate-like member, and is rotatably supported by the base member 22 to engage a striker (not shown). . Further, the pole (not shown) rotates in accordance with the operation of an engagement release rod 60 described later, and switches between the engagement holding state and the engagement release state of the hook (not shown). The spring member is configured to urge the hook (not shown) and the pole (not shown) so as to approach each other, and is constituted by a so-called coil spring.

  Next, the engagement release operation mechanism 30 will be described. As illustrated in FIG. 1, the disengagement operation mechanism 30 is configured to disengage the lock mechanism 20 provided in the vehicle seat 10, and the seat back 12 of the vehicle seat 10. Is provided on the outer shoulder portion (in other words, the upper portion and the outer portion). The disengagement operation mechanism 30 has a so-called slide push structure. When a push operation is applied to the disengagement button 32 configured in the disengagement operation mechanism 30, the disengagement operation mechanism 30 is connected to the engagement release button 32. The disengagement rod 60 is operated and transmitted to a pole (not shown) of the lock mechanism 20. And a pole (illustration omitted) is set as the structure which cancels | releases engagement with a striker (illustration abbreviation) by rotating a hook against the urging | biasing force of a spring member, and a hook rotating.

As shown in FIG. 1, the disengagement operation mechanism 30 is roughly composed of an disengagement button 32, a housing 48, and an disengagement rod 60.
First, the engagement release button 32 will be described. The disengagement button 32 is actuated by the pressing operation force of the seated person. Then, the pushing operation force is transmitted to a pole (not shown) of the lock mechanism 20 via an engagement release rod 60 described later.
As shown in FIGS. 4 and 9, the disengagement button 32 is made of a synthetic resin and has a substantially box shape. The box-shaped outer peripheral surface 33 is formed in a box shape that can be fitted to an inner peripheral surface 49 (see FIG. 10) of a housing 48 described later. The box-shaped upper surface is formed with an operation portion 34 formed in a flat shelf shape so that it can be pushed by a seated person's finger. In addition, a rod connecting portion 36 is formed in a lower portion of the outer peripheral surface 33 formed in a box shape, and a plate-like portion is formed to protrude downward. A rod insertion hole 38 through which the engagement releasing rod 60 can be inserted is formed through substantially at the center of the rod connecting portion 36. The disengagement rod 60 is connected to the disengagement button 32 when the rod insertion hole 38 is inserted. In addition, an engagement release rod 60 is inserted into the rod insertion hole 38 and connected to the rod connection portion 36, and the engagement release button 32 itself is self-supported and temporarily held on the engagement release rod 60. A temporary holding part 40 that can be formed is formed. The temporary holding portion 40 is configured such that a part of the vicinity of the portion inserted into the rod insertion hole 38 of the engagement releasing rod 60 is elastically biased from the radial direction so that the engagement releasing button 32 itself is in a self-supporting state. It is said that. In the vicinity of the rod insertion hole 38, the temporary holding portion 40 protrudes vertically from the surface of the rod connecting portion 36 and bends in the middle to be parallel to the surface of the rod connecting portion 36 in the vicinity of the rod insertion hole 38. The elastic piece 42 is formed to extend. The tip of the elastic piece 42 is formed to be elastically deformable in the direction perpendicular to the surface of the rod connecting portion 36, and a part of the disengagement rod 60 is elastic toward the surface of the rod connecting portion 36 in the radial direction. It is designed to energize power. Further, on the side part and the back surface of the lower part of the outer peripheral surface 33 formed in a box shape, there are formed projecting parts 44 that project outward. The protrusion 44 is fitted in a groove 54 (see FIG. 10) formed in an inner peripheral surface 49 of the housing 48 described later and slides to guide the engagement release button 32 in the pushing operation direction. It is configured.
Here, a part of the projection 44 is formed with a slight projection-side wrap 46 that interferes with a groove 54 of the housing 48 described later. As shown in FIG. 13, a protrusion side wrap part 46 formed on a part of the protrusion part 44 and a groove part side wrap part 56 (see FIG. 10) formed on a part of a groove part 54 described later. The amount of wrap 58 formed in this is an amount that prevents both members from falling off due to interference with each other when the housing 48 and the disengagement button 32 are mounted. The interference at the time of fitting is set to a slight wrap amount 58 that can be mounted by getting over the lap portions by manual fitting force.

Next, the housing 48 will be described.
As shown in FIGS. 5 and 10, the housing 48 is made of a synthetic resin and is formed in a cylindrical shape that covers the outer peripheral surface 33 (see FIG. 9) of the disengagement button 32. Fixing portions 51 for fastening and fixing the housing 48 are formed on both side surfaces and the back surface of the lower side of the outer peripheral surface 50 of the housing 48. Here, a shoulder bracket of the back frame 16 is configured with a second bracket 18 and a third bracket 19 which are one configuration of the skeleton of the seat and are formed in a substantially L-shaped cross section. These two members are combined and fixed to form a shelf-like base portion 19a protruding in the vehicle front direction, and the base portion 19a and the fixing portion 51 of the housing 48 are fastened and fixed. A first claw portion 52 that is engaged with the bezel 64 (see FIG. 8) is formed on the upper side of the outer peripheral surface 50 of the housing 48 so as to protrude outward. On the inner peripheral surface 49 of the housing 48, a groove 54 is formed in a straight line in the vertical direction at a position corresponding to the protrusion 44 (see FIG. 9) of the disengagement button 32. Further, a groove-side wrap portion 56 corresponding to the protrusion-side wrap portion 46 (see FIG. 9) formed in a part of the protrusion portion 44 is formed in a part of the groove portion 54. Since the configuration of the groove-side wrap portion 56 has been described above, the description thereof is omitted.

The disengagement rod 60 will be described.
As shown in FIGS. 4 and 5, the disengagement rod 60 is a member for transmitting a push operation of the disengagement button 32 of the disengagement operation mechanism 30 to a pole (not shown) of the lock mechanism 20. It is. The disengagement rod 60 is disposed between the back pad 14 and the back frame 16 configured as a skeleton of the seat and the seat pad 13 by appropriately bending a metal rod-shaped member. Further, one end 62 side is connected to the disengagement button 32 of the disengagement operation mechanism 30 disposed on the shoulder portion of the seat back 12. Further, as shown in FIG. 7, the other end 63 side is connected to a pole (not shown) of the lock mechanism 20 disposed on the side portion of the seat back 12.

  As shown in FIG. 8, in the first embodiment, a bezel 64 is attached separately from the configuration of the disengagement operation mechanism 30.
