A recliner mechanism may include a guide plate and a ratchet plate selectively rotatable relative to the guide plate. At least two pawls may be disposed between the guide plate and the ratchet plate and may be movable between a first position removed from engagement with the ratchet plate to permit relative rotation between the guide plate and the ratchet plate and a second position in contact with the ratchet plate to prevent relative rotation between the guide plate and the ratchet plate. A cam may be disposed between the guide plate and the ratchet plate and may move the at least two pawls between the first position and the second position. A control ring may be fixed to the ratchet plate and may be in selective engagement with the at least two pawls to prevent the pawls from moving from the first position to the second position.

In a seat reclining device, which eliminates a gap between a plurality of pawls and a guide wall, a wedge member is provided between at least one of the plurality of pawls and the guide wall, and a cam includes a wedge pressing cam portion for relatively rotating an upper arm relative to a lower arm by pressing the wedge member outwardly in a radial direction. The wedge member is for example made by a spherical or wedge shaped plate like member.

A rotation device includes a first frame, a second frame connected to the first frame to be rotatable within a predetermined angle, and a spiral spring including a first end and a second end, and made from a wire rod, the first end of the spiral spring being configured to be engaged with the first frame, the second end of the spiral spring being configured to be engaged with the second frame. The spiral spring is formed in such a way that mutually opposing sides of the wire rod do not make contact with each other when the second frame rotates within the predetermined angle.

A fabric seat for a chair and a method and machine for manufacturing the fabric seat. The fabric seat comprises a seat frame that supports the outer circumference of a fabric material. The seat frame comprises grasping members that secure the fabric to the seat frame and retain the desired stretch in the fabric. The grasping members can be teeth. A cover is also provided, which is snapped onto the circumference of the seat frame, to trap the fabric and protect the user from the grasping members.

The present invention relates to a device for adjustment of the level of inclination of the back part of a motor vehicle seat having a device part (2) connected to the seat part and a device part (3) connected to the backrest, which can be pivoted opposite to each other about a pivot axis (14), wherein both device parts (2, 3) have parts of gearings (4, 5) forming a swash mechanism, which roll over each other under the influence of cam means (11) that can be rotated about a pivot axis (14). The drive of the cam means (11) is provided via a two-part carrier, comprised of a metal carrier boss (17) and a metal carrier plate (18) non-rotatingly connected therewith. The carrier boss (17) has a collar (17.2) for axial bracketing of the device parts (2, 3) on one side of the device for adjustment of the level of inclination (1). The object is to configure this type of device for adjustment of the level of inclination, so that no longer requires an additional locking ring for axial bilateral bracketing of the device parts (2, 3). The solution resides in the fact that the carrier plate (18) is fastened axially to the carrier boss (17) on the other side of the device for adjustment of the level of inclination (1) for completion of the bracketing of the device parts (2, 3).

A method for retrofitting an adjustable chair including a seat, a pedestal base, and a gas cylinder that extends therebetween is provided. The method includes the steps of uncoupling the gas cylinder from the chair, and coupling a height adjustment mechanism to the chair that is configured to electrically adjust a height of the seat relative to the pedestal base. The height adjustment mechanism coupled to the chair being retrofitted includes a limit switch that is configured to limit an amount of movement of the height adjustment mechanism. The method also includes the step of coupling the pedestal base to the height adjustment mechanism.

A vehicle seat recliner in which a lock-up gear and a sector gear are used to adjust the tilt of the back of the seat. The sector gear adjusting the tilt of the back of the seat is fixed at a main bracket installed on one side of the car seat and comprises an adjustment lever rotating around a first rotation axis and connected to the connection lever rotating around a second rotation axis. A cam is interlocked with the adjustment lever and is installed on the first rotation axis. The motion of the lock-up gear is guided so that the lock-up gear and the sector gear are locked and released completely all at once.
