A reclining device for a vehicle seat includes a rotary bracket having a center portion rotatably connected to a first frame and having a first locking section and a second locking section connected to the first locking section, and a cam configured to rotate about a center portion connected to the first frame and having a locking portion provided at one end thereof and positioned in the first locking section or the second locking section so as to be locked.

A recliner including a ratchet and a guide mounted in an axial direction, and a lock mechanism configured to lock relative rotation between the ratchet and the guide by meshing in a radial direction, the lock mechanism including a plurality of poles which is configured to be supported in a circumferential direction by the guide and has outer circumferential teeth configured to mesh with inner circumferential teeth formed on the ratchet as the poles are pushed outwards in the radial direction to be moved, the plurality of poles including a specific pole, wherein the specific pole includes a pressing portion configured to contact a restraint portion of the guide from an inner side in the radial direction so as to be restrained from moving in the circumferential direction as the specific pole is pushed outwards in the radial direction by an operating cam to be moved.

A locking device for a vehicle seat. The recliner includes a plate holder including a first catch protrusion on one of a plurality of guide blocks, a sector gear including an internal gear on an inner surface thereof, a plurality of pawl teeth each configured to be moved between a pair of the guide blocks, the pawl teeth including catch hooks on portions of inner surfaces thereof, an operation cam including a second catch protrusion protruding therefrom; and a return spring having a spiral shape, the return spring including a center inner end portion hooked and supported on the second catch protrusion and an outer end portion hooked and supported on the first catch protrusion, wherein a support protrusion protrudes from the operation cam to support the return spring while making point contact with a center inner surface of the return spring.

A seat recliner for a vehicle is provided and includes: a first plate; a second plate coupled with the first plate to define an inner space; a locking gear provided in the inner space, and provided with external teeth engaged with the first plate or the second plate; a locking cam configured to move the locking gear; an input member configured such that a first end thereof passes through the first plate and is coupled with a center of a locking cam to transmit torque thereto, and a second end thereof is exposed outside the first plate; and an elastic member wound around an outer circumferential surface of the second end of the input member, and configured such that a first end thereof is stopped by the input member, and a second end is stopped by an outer side of the first plate, thereby providing a restoring force.

A locking mechanism includes a plate and a pawl. The plate includes a peripheral lip having an interior face that defines a plurality of teeth. The pawl defines a central axis and includes a plurality of pawl teeth including a first middle tooth and a second middle tooth. The first middle tooth is positioned on a first side of the central axis and has a first flat face facing the central axis and a first curved face facing away from the central axis. The second middle tooth is positioned on an opposing second side of the central axis and has a second flat face facing the central axis and a second curved face facing away from the central axis. The pawl is positionable between (i) a first position where the pawl does not engage with the plate and (ii) a second position where the pawl engages with the plate.

The invention relates to a latching fitting (10), in particular for a seat of a motor vehicle. The latching fitting (10) comprises a base plate (20), a cover plate (30), at least one blocking arm (40, 140) and an actuating plate (50). The cover plate (30) is rotatable relative to the base plate (20) and has an internal toothing (31). The blocking arm (40, 140) is arranged on the base plate (20) and is pivotable between an unlocked position, in which rotation of the cover plate (30) relative to the base plate (20) is possible, and a locked position, in which rotation of the cover plate (30) relative to the base plate (20) is blocked. The actuating plate (50) is rotatable relative to the base plate (20) and shifts the blocking arm (40, 140) between the unlocked position and the locked position. The internal toothing (31) has first blocking teeth (34) which have a vertex (35) and which are formed asymmetrically with respect to a radial axis (A) which runs through the vertex (35). The blocking arm (40, 140) has second blocking teeth (44) which are adapted for meshing with the first blocking teeth (34).

A recliner for a vehicle seat is configured such that a plurality of stop protrusions is provided along an edge of a center hole formed in a control plate, and fore-end corners of the stop protrusions are stopped by the outer circumferential surface of a rod part of an input member when the rod part of the input member passes through the center hole of the control plate, whereby the coupling and assembly of the input member is performed by the stop protrusions of the control plate.

An actuating device (100) has a first part (5a; 334; 434) and a second part (5b; 310; 412) which can be pivoted about a first axis (A) relative to the first part (5a). A first segment (140) can be coupled to the first part. A second segment (150) can be rotated about the first axis (A) relative to the first segment (140) and can be connected to a locking device of a component (20) and/or to a locking device (350; 450) of another component (330; 430). Rotation of a deflecting element (120) moves a transfer element (130) such that the second segment (150) is not rotated about the first axis (A). Changing a distance between the first axis (A) and a second axis allows the second segment (150) to be rotated about the first axis by the transfer element (130). A vehicle seat includes such an actuating device (100).
