  • Patent number: 10870371
    Abstract: An operation device (1) includes first bases (81A, 81B) and/or second bases (72A, 72B) that are elastically deformable in the direction of a pivot axis (X1) so that a shaft (120) can be inserted into a shaft hole (110). A first protrusion (121) is formed on a distal end portion of the shaft and projects radially outward from an outer sliding surface (120E). The first bases (81A, 81B) include a first escape section (111) recessed radially outward from an inner sliding surface (110E). The first escape section allows the first protrusion to pass through the first base when the shaft is being inserted into the shaft hole with an operation member (80) located in an initial position. A first slip-off preventing section (113) circumferentially adjacent to the first escape section prevents the shaft from coming out of the shaft hole when the operation member is pivoted from the initial position to an end position.

  • Patent number: 9090179
    Abstract: A latch mechanism of a vehicle seat reclining device includes a plurality of latch holes formed in a rail along a central axial line, a slider hole penetrating through a slider so as to face the respective latch holes, a support portion provided on the slider, and a movable portion displaceably supported by the support portion and having a latch projection that is engageable with the respective latch holes while passing through the slider hole. A clearance is defined in the direction of the central axial line between the slider hole and the latch projection. One or more shock absorbing members is (are) provided on opposing first and second inner surfaces of the slider hole and abut against the latch projection while being resiliently deformed to suppress the generation of undesirable rattling noise in case a force causes the latch projection to oscillate within the engaged latch hole.

  • Patent number: 8439446
    Abstract: A vehicle seat reclining device comprises a latch mechanism having latch holes defined in a rail along a central axial line, a slider hole penetrating through a slider so as to be alignable with the latch holes, a support portion slidably supported on the slider, and a lever coupled to the support portion so as to be pivotable about an axis that is substantially parallel to the central axial line. A latch claw is extends from the lever and is engageable with the respective latch holes via the slider hole. A first amount of play is provided between the support portion and the lever in a direction parallel to the central axial line. A second amount of play, which is less than the first amount play, is provided between the slider hole and the latch claw in the direction parallel to the central axial line.

  • Patent number: 8251430
    Abstract: A vehicle seat reclining device comprises a slider, which has an engaging portion and rotatable portions, and a rail having engagable portions. The engaging portion is retractable from the rail during a backrest tilting operation and advances towards the rail to lock the backrest in a selected tilted position. The engagable portions engage with the advanced engaging portion to prevent sliding of the slider relative to the rail. Clearances are provided between the rail and the slider in a width direction that is orthogonal to a rotational axis defined in the engaging portion. The width direction is also orthogonal to the central axial line of the rail. The rotatable portions project from the slider in a radial direction from the rotational axis and narrow the clearances so as to guide the rotation of the slider relative to the rail around the rotational axis.
