  However, after attaching the operation lever to the base, it is necessary to attach a lid to the operation lever. This complicates the operation when attaching the lever device to the seat body. Therefore, a lever device that can be easily attached to the seat body is conventionally required.

  In order to solve the above-mentioned problems, the present invention is a vehicle seat lever device having a configuration as described in each claim. According to one aspect, the present invention is movable to a base mounted on the seat body, an operating lever movably provided on the base, a closed position that covers a part of the base, and an open position that exposes the part. And a lid attached to the base. The base includes a lid attaching portion to which the lid is movably attached, a stopper for releasably holding the lid in the open position, and an engaging portion to be engaged with the lid in the closed position.

  Thus, the lid can be pre-attached to the base before the base is attached to the seat body. Therefore, the lid is not stored separately from the base, but can be stored while attached to the base. Thus, the parts management of the rail device becomes easy. Further, when the lever device is attached to the seat body, the lid is attached to the base in advance, so that it is not necessary to select the lid when attaching to the seat body. Further, since the lid is held in the open position with respect to the base, it is difficult to get in the way when a screw or the like is attached to a part of the exposed base. Then, a screw etc. can be covered by covering this part with a lid.

The recess 2a3 covers a lower region of the inner periphery of the annular portion 2a1 and is recessed closer to the seat back 12 than the plate portion 2a2.

  As shown in FIGS. 4 and 6, a mounting hole 2d, an engaging portion 2f, and a lid mounting portion 2e are formed in the recess 2a3. 2d of attachment holes are formed in the center area | region of the bottom face of recessed part 2a3, and the screw 5 can be inserted. The screw 5 is screwed into a bracket 12 c provided on the frame 12 b of the seat back 12 to attach the base 2 to the seat back 12.

  As shown in FIG. 6, the engaging portion 2f has a hole formed in the upper portion of the bottom surface of the recess 2a3. The claw 4b of the lid 4 is inserted into the hole of the engaging part 2f, and the claw 4b is engaged with the hole edge of the engaging part 2f. Accordingly, the lid 4 can be held in the closed position with respect to the base 2 (see FIG. 9).

  As shown in FIGS. 4 and 6, the lid mounting portion 2 e is formed on both the left and right edges of the bottom surface of the recess 2 a 3. The lid attaching part 2e has a long groove 2e1 and rails 2e2, 2e3. The long groove 2e1 penetrates the bottom surface of the recess 2a3 and extends in the vertical direction. The rails 2e2 and 2e3 are formed on the left and right edges of the long groove 2e1, and the hook 4c of the lid 4 is slidably attached thereto.

  Stoppers 2g and 2h are formed on the upper portions of the rails 2e2 and 2e3 as shown in FIGS. The stoppers 2g and 2h protrude from the rails 2e2 and 2e3 to the back side. The stoppers 2g and 2h are releasably engaged with the hooks 4c of the lid 4 slid along the rails 2e2 and 2e3.

  As shown in FIGS. 4 and 6, the lid 4 integrally includes a lid body 4a, a claw 4b, and a hook 4c. The lid body 4 a has a shape that can cover the recess 2 a 3 of the base 2. The claw 4b extends toward the base 2 from the upper part of the lid body 4a. The claw 4b has a neck 4b1 and a head 4b2. When the claw 4b is inserted into the engaging portion 2f of the base 2, the neck portion 4b1 is elastically deformed and returned to engage the head portion 4b2 with the hole edge of the engaging portion 2f.

  As shown in FIG. 6, the hooks 4c are formed on both the left and right sides of the lower portion of the lid body 4a. The hook 4c integrally includes an extending portion 4c1, an engaging portion 4c2, and a rib 4c3. The extension part 4c1 extends toward the base 2 from the left and right sides of the lower part of the lid body 4a. The engaging portion 4c2 extends downward from the end portion of the extending portion 4c1. The rib 4c3 stands on the left and right side edges of the lid body 4a.

  When the lid 4 is attached to the base 2, as shown in FIGS. 7 and 8, the hook 4c is inserted from the top of the lid attaching portion 2e. The engaging portion 4c2 of the hook 4c is slidably supported by the rails 2e2 and 2e3. When the lid 4 is moved upward, the upper part of the engaging part 4c2 comes into contact with the stopper 2h, and the lower part of the engaging part 4c2 comes into contact with the stopper 2g. The claw 4b of the lid 4 abuts on the main body 2a of the base 2, and the lid main body 4a is elastically deformed. The engaging portion 4c2 elastically contacts the stoppers 2g and 2h and the claw 4b elastically contacts the base 2 by the elastic force of the lid body 4a.

  As a result, the lid 4 is releasably held in the open position as shown in FIG. In the open position, the lid body 4a is positioned above the recess 2a3 of the base 2 and exposes the recess 2a3. Therefore, the base 2 can be attached to the bracket 12c with the screw 5 while holding the lid 4 in the open position with respect to the base 2. The lid 4 in the open position is located in a gap 3c formed between the operation lever 3 and the base 2 as shown in FIG. Therefore, the lid 4 does not get in the way when the screw 5 is fastened to the bracket 12c.

  After the base 2 is attached with the screw 5, the lid 4 is moved from the open position to the closed position below. As a result, the hook 4c of the lid 4 moves along the lid attaching portion 2e as shown in FIGS. 5 and 7, and the engaging portion 4c2 of the hook 4c engages with the stopper 2i at the lower end of the lid attaching portion 2e. The claw 4b of the lid 4 enters the hole of the engaging portion 2f and engages with the hole edge. As a result, the lid 4 is held in the closed position as shown in FIG. 4, and the screw 5 and the recess 2a3 of the base 2 are covered by the lid body 4a.

  As shown in FIGS. 1 and 2, when the seat device 10 is moved from the use state to the forward tilt state by operating the lever device 1, the operation lever 3 is rotated with respect to the base 2. The operation lever 3 rotates to pull a cable (not shown), and the cable operates the reclining device 13, the stopper device 14, and the lock mechanism 15 c of the slide device 15.

  The reclining device 13 is operated so that the seat back 12 can rotate with respect to the seat cushion 11 and the seat back 12 falls forward. The stopper device 14 is operated to restrict the rotation of the seat back 12 to a predetermined forward tilt angle. The lock mechanism 15 c is operated to allow the seat body 17 to slide with respect to the floor 16. As a result, the seat 10 changes from the use state to the forward tilt state.

  As described above, the lever device 1 covers the base 2 mounted on the seat main body 17, the operation lever 3 provided movably on the base 2, and a part of the base 2 (recess 2a3) as shown in FIG. A lid 4 is attached to the base 2 so as to be movable to a closed closed position and an open position exposing the part. The base 2 includes a lid attaching portion 2e to which the lid 4 is movably attached, stoppers 2g and 2h for releasably holding the lid 4 in the open position, and an engaging portion 2f to which the lid 4 is engaged in the closed position. Have.

  Accordingly, the lid 4 can be attached to the base 2 in advance before the base 2 is attached to the seat body 17. Therefore, the lid 4 is not stored separately from the base 2 but can be stored in a state of being attached to the base 2. Thus, parts management of the rail device 1 is facilitated. Further, when the lever device 1 is attached to the seat body 17, the lid 4 is attached to the base 2 in advance, so that it is not necessary to select the lid 4 when attached to the seat body 17. Further, since the lid 4 is held in the open position with respect to the base 2, it is unlikely to become an obstacle when attaching the screw 5 or the like to a part of the exposed base 2. Thereafter, the screw 5 and the like can be covered by covering the part with the lid 4.

  As shown in FIG. 6, the lid attaching portion 2 e has rails 2 e 2 and 2 e 3 to which the lid 4 is slidably attached. To position. The lid 4 includes a lid body 4a that covers the part of the base 2, and a hook 4c that extends from the lid body 4a and is slidably attached to the rails 2e2 and 2e3. Therefore, the rails 2e2 and 2e3 and the hook 4c can be covered and covered by setting the lid 4 in the closed position, like the part of the base 2.

  As shown in FIG. 4, the operation lever 3 has a mounting portion 3 a that is rotatably attached to the base 2 and a tip portion 3 b that forms a gap 3 c between the base 2. The lid 4 is located in the gap 3c at the open position, and is pulled out of the gap 3c by sliding from the open position to the closed position. Therefore, the operation lever 3 can be operated by a user's finger or the like inserted through the gap 3c. Since the lid 4 is located at the open position using the gap 3c, the lever device 1 can be configured smaller than when the lid 4 is opened at other positions.

  As shown in FIG. 8, the claw 4b is formed at the first end of the lid 4 in the sliding direction, and the hook 4c is formed at the second end of the lid 4 located on the opposite side of the first end. The lid body 4a is elastically deformed at the open position, and the hook 4c is elastically engaged with the stopper 2g by the elastic deformation, and the claw 4b is elastically contacted with the base 2. Therefore, the lid 4 can be stably held in the open position by utilizing the elastic deformation of the lid body 4a.
