| 20090134682 | SEAT RECLINING DEVICE - In a seat reclining device, reclining mechanisms that are respectively provided on right and left sides of a seat are constructed such that locking and unlocking motion thereof can be performed in synchronism with each other via a connection member. A connection structure of the connection member and a operation shaft is constructed as a transmission preventing mechanism for preventing transmission of the unlocking motion between the reclining mechanisms when a load is laterally disproportionately applied to the seat back in which the reclining mechanisms are in a locking condition such that a relatively different rotational displacement that permits to release the locking condition is generated between the reclining mechanisms that are arranged in rotationally synchronism with each other. | 05-28-2009 |

The seat assembly includes a leg unit and a seat plate mounted to the leg unit. The backrest assembly includes a backrest plate and an engaging frame interconnecting pivotally the backrest plate and the seat assembly. The support assembly includes at least one telescopic rod interconnecting the engaging frame and the leg unit. The actuating mechanism includes at least one actuating member corresponding in position to the telescopic rod, and a drawing unit coupled to the actuating member and operable for driving the actuating member to actuate length adjustment of the telescopic rod so as to adjust inclination of the backrest assembly relative to the seat assembly. | 06-07-2012 |
| 20140300166 | VEHICLE SEAT - A reclining device includes an operating shaft that is inserted through the reclining device in its axial direction to be mounted, and is adapted to release the reclining device from a locked position, and a torsion spring mounted between an outer end portion of the operating shaft which protrudes from the reclining device outward in a width direction of the seat, and a frame portion that is located outside the reclining device in the seat width direction. The operating shaft is constantly biased by the torsion spring in a rotational direction for locking the reclining device. The torsion spring is mounted onto the outer end portion of the operating shaft in the axial direction from an outer side of the seat, and has an inner end portion which is engaged with the operating shaft, and an outer end portion which is engaged with the frame portion. | 10-09-2014 |
| 20150374565 | BACKREST ANGLE ADJUSTMENT SYSTEM ON A SEAT FOR A PHYSICALLY DISABLED PERSON - The invention relates to a seat, backrest, lateral support bracket, and footrest that are able to be adapted to suit the needs of a physically disabled user. In general, the seat comprises a base frame, a seat base that is supported by the base frame, and a backrest. The backrest may be adapted to tilt with respect to the seat base and comprises a backrest angle adjustment system including a vertically extending angle adjustment slot located centrally on the backrest support and a pair of links pivotally attached to the seat frame and the angle adjuster wherein the angle adjuster comprises a lock with a projection through the angle adjustment slot and a fastener that engages with the projection. | 12-31-2015 |
| 20160022038 | SEAT BACK LINKING MECHANISM - A seat back linking mechanism includes a base frame having a pivot portion; a back frame pivotally connected to the base frame; an actuation member slidably coupled to the back frame; a linkage having a first link and a second link pivotally coupled together, the first link and the second link being respectively pivotally coupled to the pivot portion of the base frame and the actuation member, and a drag portion; and a drag member having a drag portion adapted for dragging the drag portion of the linkage. | 01-28-2016 |
| 20160023575 | ANGULAR ADJUSTMENT DEVICE FOR A VEHICLE SEAT - A hinge mechanism for a motor vehicle seat allowing angular adjustment of a backrest relative to a seating portion. The hinge mechanism includes first and second hinge plates, a control member moving locking elements and biased to a locking position by first springs, and a drive shaft biased to a first rest position by second springs. The second springs are housed between the first and second hinge plates and are supported on the first plate. | 01-28-2016 |

| 20100109407 | Device With A Limit Switch And Trunnion - Dental devices with cylinders, trunnions, and limit switches, and a method are provided. The dental devices include a cylinder and a trunnion having a cavity and an outer surface. A portion of the cylinder is slidably mounted within the cavity of the trunnion, and a portion of the cylinder protrudes out of the trunnion. The limit switch is coupled to the outer surface of the trunnion, with the limit switch is operable to contact the cylinder. Separation of the limit switch and the cylinder causes actuation of the limit switch, and the actuation of the limit switch inhibits a downward movement of the device. Alternatively, the limit switch may be coupled to the portion of the cylinder that protrudes out of the trunnion, with the limit switch operable to contact the trunnion. As such, separation of the limit switch and the trunnion causes actuation of the limit switch. | 05-06-2010 |
| 20110266853 | DUAL USE OFFICE AND LEISURE CHAIR - A dual use office and leisure chair is provided that overcomes the shortcomings of existing technology. A chair back is provided that is hingeably attached with the handrails. Installation of a pneumatic rod and adjustment device hingeably attached to the chair back enables adjustment to different inclination angles for the chair back, the inclination angle is selectively fixed at any angle within the travel of the pneumatic rod. Simple adjustment, easy use, and long lifetime make it possible to achieve office and leisure dual use for the chair. | 11-03-2011 |

| 20090146478 | Reclining Adjuster - Reduces backlash and clearance in a thrust direction of a worm when engaging a seat back to more securely prevent the generation of abnormal noise that before. A movable bearing | 06-11-2009 |
| 20100148558 | LINEAR RECLINER ASSEMBLY WITH THREADED LINEAR DRIVE ROD AND ROTATABLY ENGAGED GEAR STOP - A linear recliner assembly in use with a seat having a seat back pivotally engaged relative to a seat bottom. A housing exhibits a communicating interior between a first and second ends. A drive rod is supported in linearly displaceable fashion from the first end and is secured to the seat bottom. The second end pivotally engages the seatback spaced from its pivot point. A rotatable gear located at a fixed lineal position within the housing receives the drive rod in threadably inter-engaged fashion. A trigger mechanism pivotally secured to the housing exhibits a downwardly biased detent communicating through an opening in the housing to seat between succeeding teeth of the gear. A spring supported within the housing contacts the drive rod. Upon release of the detent, a reclining force applied to the seatback results in displacement of the housing against the drive rod to bias the spring. The spring influencing the drive rod in a reverse direction such that, upon release of said detent when the seatback is in the reclined position, the spring influences the seatback to reverse pivot to a returned upright position. | 06-17-2010 |
