| 发明名称 | Adjustable seating | ||
| 摘要 | Among other things, a seat includes a base; a back-supporting surface coupled to the base; and a seating surface movable relative to the base in a direction of motion toward and away from the back-supporting surface. The back-supporting surface has a lower portion nearer the seating surface that is movable, relative to an upper portion of the back-supporting surface that is farther from the seating surface, in the direction of motion as the seating surface moves in the direction of motion. | ||

| 主权项 | 1. An apparatus comprising a base, a seat mounted to be movable forward and backward through a range of motion relative to the base, a seat back mounted to be, during all or at least a portion of operation of the apparatus, simultaneously (a) movable in rotational motion about a physical rotational axis relative to the seat independently of the forward and backward motion of the seat, (b) movable in an upward and downward motion relative to the seat, independently of motion of the seat forward and backward and independently of the rotational motion about the physical rotational axis, (c) biased for the upward motion, and (d) to prevent the rotational motion during at least a portion of operation of the apparatus. | ||
