Disclosed is a reclining device for a vehicle seat, the reclining device includes: a flange having inner teeth; a gear plate having an outer tooth part and a coupling part, the outer tooth part provided with outer teeth and engaged with a part of the inner teeth of the flange in an eccentric state with the flange, and the coupling part having a locking step; an input device provided inside a through hole of the gear plate and coupled to a shaft to allow the flange and the gear plate to be eccentric with each other and to perform relative rotation when the shaft is rotated; and a bracket having an insertion hole, and a locking protrusion that is locked by the locking step of the coupling part formed at an inner circumferential surface of the insertion hole to prevent the relative rotation with the gear plate.

A child safety seat includes a seat portion, a backrest assembly including a first and a second backrest portion slidably connected with each other and a headrest slidably connected with the second backrest portion, the first backrest portion being connected with the seat portion, and a backrest adjusting system disposed on the backrest assembly and configured to provide a first stage of height adjustment where the first and second backrest portions are locked with each other and the headrest is movable relative to the first and second backrest portions for adjustment, and a second stage of height adjustment where the second backrest portion is locked with the headrest and unlocked from the first backrest portion so that the headrest and the second backrest portion are movable in unison relative to the first backrest portion for adjustment.

A vehicle seat including a seat bottom, a seat back rotatable relative to the seat bottom, and a damper assembly. The assembly includes a bracket coupled between the seat bottom and the seat back, and a cam plate coupled to the bracket and to the seat back. The cam plate is rotatable relative to the bracket and in a fixed orientation relative to the seat back such that the cam plate is rotatable with the seat back relative to the seat bottom. The cam plate includes an arcuate slot. The assembly also includes a linear damper including a first end coupled to the bracket and a second end coupled within the arcuate slot. The second end is translatable within the arcuate slot such that the linear damper is configured to provide selective damping to the seat back based on an orientation of the seat back relative to the seat bottom.

A seat assembly includes a seat back that is pivotable about an axis of rotation, and a reclining assembly. The reclining assembly includes a base, a carrier secured to the base and including a rod guide, a curved rod interfacing the rod guide, a spring having a fixed end and a rotatable end, and a curved spring housing that extends over the spring.

A reclining cushion assembly for a seat includes a fixed portion and a movable portion mounted to the fixed portion. The movable portion is movable between an upright position and a reclined position. At least one reclining and locking mechanism is mounted to the fixed portion. The at least one reclining and locking mechanism is movable between a first position and a second position. The at least one reclining and locking mechanism is operable to engage the movable portion to transform the movable portion from the upright position to the reclined position.

The present invention relates to an adjustment device for adjusting the inclination of the backrest (14) of a seat (10) of a vehicle, which allows to perform both quick adjustments of large angular amplitude and fine adjustments. According to a possible embodiment of the invention, the adjustment device comprises separate control elements (20, 22) for performing quick adjustments and fine adjustments, respectively, of the inclination of the backrest (14). According to another possible embodiment of the invention, the adjustment device comprises a single control element (20) for performing both quick adjustments and fine adjustments of the inclination of the backrest (14).

A vehicle seat, including a seat underframe and a backrest mounted pivotably with respect to the seat underframe about a backrest pivot axis, the inclination of which backrest may be adjusted in a comfort range by pivoting about the backrest pivot axis by a fitting arrangement. The fitting arrangement is provided on a first of two longitudinal backrest sides of the backrest and a locking device is provided remote from the first longitudinal backrest side, which locking device is provided to lock the backrest so as to prevent pivoting about the backrest pivot axis beyond the comfort region in the event of a crash and which is coupled to the fitting arrangement to actuate the locking device when the backrest is actuated beyond the comfort region and to release a locking provided by the locking device by actuating the fitting arrangement.

A system, method and apparatus for a transit seating system including multiple seat frames, each seat frame including, at least one forward support and at least one rearward support. The at least one forward support and the at least one rearward support are capable of being detachably secured to a transit vehicle floor. A seat back height track system is vertically and slideably coupled to the seat frame. A seat back subframe is coupled to the seat back height track system. A seat base frame is coupled to the seat back height track system through a seat hinge. The at least one forward support is capable of overlapping the at least one rearward support when at least two of the seat frames are in a nested or fully compressed or stowed configuration.

A brake device for a motor vehicle seat includes a braking section for holding a pinion shaft in a braked and locked state. The braking section includes a housing including an inner periphery including a braking surface. First and second lock plates are arranged opposite to each other with respect to the pinion shaft in the housing. The pinion shaft includes a rectangular shaft part disposed between the first and second lock plates, wherein the rectangular shaft part includes an acting surface structured to be in contact with the first lock plate. The first lock plate is pressed on the braking surface of the housing by the acting surface. The acting surface includes a crest line corresponding in position to the center of the pinion shaft, and an inclined surface that descends from the crest line toward a radially outward end of the rectangular shaft part.

A brake device for a motor vehicle seat is composed of a brake assembly, a tooth assembly, and a lever assembly. The brake assembly includes a housing, a pinion shaft, a braking component, and a drive wheel that are structured to be self-held in an assembled state by mechanical interaction thereamong. The tooth assembly includes a holder plate and a tooth plate that are structured to be self-held in an assembled state by mechanical interaction therebetween. The lever assembly includes an input lever, a cover, a coil spring, and a lever bracket that are structured to be self-held in an assembled state by mechanical interaction thereamong. The brake assembly, the tooth assembly, and the lever assembly are arranged and assembled together in an axial direction.
