A recliner assembly for a vehicular seat of the type including a backrest hingedly connected to a seat base and capable of being reclined. The recliner assembly includes an outer gear and includes an internal teeth arranged circumferentially about an axis A. The assembly also includes an inner gear including at least one tooth engaging member selectively moveable into and out of engagement with the internal teeth of the outer gear. A retainer is attached to the outer gear in order to retain the inner gear from lateral movement along axis A. The retainer is configured for mounting to the outer gear and the inner gear is configured for mounting to at least one of a top plate and a base plate. The retainer, outer gear, and inner gears can be formed from a fine-blanked steel material and simply welded together to improve recliner strength while reducing assembly costs.

The present invention relates to a Taumel-type reclining device and provides a reclining device in which clattering does not occur. On either the inner side or the outer side of a first wedge-shaped member 71 and a second wedge-shaped member 73, a driving ring 75 is disposed. A abutting portion of the driving ring 75 is formed such that, in a case where the internal gear 61 and the external gear 63 are in a locked state, a force to move the first wedge-shaped member 71 and the second wedge-shaped member 73 in a direction in which engagement of the inner teeth 61c of the internal gear 61 and the outer teeth 63a of the external gear 63 becomes deeper can be generated.

A method for producing a vehicle seat fitting involves a sliding bearing bushing (28) being pressed in the axial direction into a receptacle in a first fitting part (11). The pressed-in sliding bearing bushing (28) has a radially protruding securing region (28b). The securing region (28b) is formed before or after the pressing-in operation.

A wobble joint fitting for an adjustment device of a motor vehicle seat comprises a first fitting part, a toothed eccentric gear that has an eccentric hole and a collar, and an eccentric comprising a rotatable drive part, a control part and wedge segments, the control part comprising control surfaces that come to abut against the wedge surfaces. The fitting further comprises a second fitting part that is adjustable with respect to the first fitting part. A latching part is provided which has at least one latching tooth, biased only in an actuation position of the latching part into engagement with a latching recess, and having an actuating flank. The control part comprises an actuating portion which abuts against the actuating flank and, during a rotary movement of the control part, presses the latching tooth into abutment against the collar, and biases it into engagement into a latching recess.

In an eccentric-drive equipped seat reclining device including a cover having internal teeth, a base member, an external gear having fewer external teeth than a number of the internal teeth, a pair of wedge-shaped members and a guide plate located in an eccentric space between the cover and the external gear, a spring biasing the pair of wedge-shaped members apart from each other, and a driving member for circumferentially pushing the pair of wedge-shaped members, the external gear has a cylindrical protrusion. The base member has a first axially-recessed portion for press-fitting the external gear to the base member, a second axially-recessed portion accommodating the cylindrical protrusion, and a third axially-recessed portion accommodating the spring. Protrusions, formed integral with an annular outer peripheral portion of a backface of the second axially-recessed portion, are fitted to respective recessed portions of a seat-cushion side arm.

A disc recliner includes a fixed plate having a plurality of outer teeth and a movable plate having a plurality of inner teeth meshingly engageable with the outer teeth to allow rolling movement of the movable plate relative to the fixed plate. A pair of wedges defining an eccentric is rotatably mounted between the fixed and movable plates and rotation of the wedges causes the rolling movement of the movable plate. An anchor is disposed between the wedges for rotation therewith. A lock plate is coupled to the anchor and is movable between a locked position engaged with the fixed plate to prevent rotation of the wedges and an unlocked position disengaged with the fixed plate to permit rotation of the wedges. A cam actuates the lock plate from the locked position to the unlocked position and rotates the wedges thereby causing the rolling movement of the movable plate.

The dial recliner includes a holder and a sector gear and also comprises a brake spring, a cam, a pair of clutch shoes and a spring which are accommodated and supported between the holder and the sector gear. The dial recliner also comprises a housing to maintain a combined state between the holder and the sector gear. The holder has inner teeth of a ring shape at its outer circular part and a boss at its center part to support a shaft. The sector gear has outer teeth to intermesh with the inner teeth of the holder. When intermeshed, the boss of the holder and a shaft hole of the sector gear become eccentric between their centers. The clutch shoe is supported by the brake spring which is elastically held around the boss of the holder so that a circular drifting movement of the clutch shoe can be prevented.

An adjusting device for a vehicle component, in particular for the seat back of a vehicle seat, has a first and a second fitting part which are disposed along an axis of rotation. The relative position of the two fitting parts with respect to one another can be changed. A torque is transmitted by a drive to a gear which rolls on the second fitting part and thereby adjusts the second fitting part.

A fitting for a vehicle seat is disclosed, in particular for a motor vehicle seat. First and second fitting parts are geared with one another via a meshing gearwheel and gear rim. A peripheral eccentric is driven by a drive element for driving a relative rolling movement of the gearwheel and the gear rim, and the first fitting part receives the eccentric which is supported on the second fitting part. A blocking element blocks the eccentric in the non-driven state of the fitting via toothing on the first fitting part, and releases the eccentric when driven. The gear rim is formed on the first fitting part and the gearwheel is formed on the second fitting part.
