摘要： An infant highchair includes a standing frame, a seat and a locking mechanism. The seat is pivotally connected with the standing frame and has a seating surface, the seat being rotatable between a first and a second position, and the locking mechanism being operable to lock the seat in the first and second position. The first position allows a child to sit in contact with the seating surface, and the second position is suitable to receive installation of a removable child seat over the seat while disabling seating of a child on the seating surface.

摘要： A seat assembly including a seat, a backrest and a mounting assembly mounting the seat in a near horizontal orientation for movement along an upwardly concaved arcuate seat path having a center of curvature proximate the center of mass of a person seated on the seat, and mounting assembly further mounting the backrest in a near vertical orientation for movement independently of the seat along a forwardly concaved arcuate path having a center curvature proximate the center of mass of the person. An adjustment assembly is provided for adjusting the radius of curvature of the path of motion of the backrest. Also provided are a backrest tilt adjustment assembly, an armrest adjustment assembly, a seat biasing assembly and a seat motion latching assembly. A method of self-adjusting support and alignment of a backrest also is disclosed.

摘要： A seat cushion includes a cushion body, a weight measuring unit coupled to the cushion body, a tilt adjusting unit, a storage unit storing pre-established mapping data, and a controlling unit. The weight measuring unit measures, when a user is sitting on the cushion body, weight of the user applied to the cushion body so as to generate a result of weight measurement. The controlling unit is connected to the weight measuring unit, the tilt adjusting unit and the storage unit, and controls, when the seat cushion is operated in an automatic mode, the tilt adjusting unit to adjust a seat angle of the cushion body with respect to a horizontal reference plane based on the result of weight measurement, a height value and the mapping data.

摘要： A rocking chair includes a seat, a backrest that is tiltable rearward, a locking spring portion that imparts resistance to the rearward tilting of the backrest, and a resilience adjustment member that changes the degree of resistance of the spring portion to the rearward tilting of the backrest. The resilience adjustment member is a cam that is rotationally operable by a person seated on a seat and the position in which rocking load due to the rearward tilting of the backrest is applied to the spring portion is changed by the cam, so that moment applied to the spring portion changes and the degree of resistance of the spring portion is adjusted.
