    摘要： A one-piece shell chair (10) includes an unitary integrally formed shell body (12) having a flexurally supported seat pan (14) and a flexurally supported backrest (16) defined in part by an H-shaped opening (20) in the shell body. The backrest (16) and the seat pan (14) resiliently flex as independent units in response to an occupant's body shape, size, posture and positioning. Integral, flexible straps join the backrest (16) to the seat pan (14) to permit resilient flexing of the backrest (16) with respect to the seat pan (14) about an axis through the occupant's hip joint to minimize shear between the backrest and the occupant's back during flexing movement of the backrest 16 with respect to the seat pan 14. The seat (12) is mounted to a tilt mechanism (28) which pivots the seat (12) about an axis forward and below the front edge (14a) of the seat pan (14) enabling the user's feet to remain stationary on the floor. Accordingly the seat (12) and tilt mechanism (28) provide a comfortable, convenient and accommodating chair (10).

    摘要： A reclining chair (10) having a seat (12), backrest (14), side supports (16) and a reclining mechanism which includes a backrest bracket (34) rigidly affixed to the backrest (14) and pivotably mounted to a side support bracket (18), the side support bracket (18) being rigidly affixed to a side support (16). A seat support bracket (30) is rigidly affixed to the seat (12) and pivotably mounted to a side support bracket (18). A coupler link (40) has one end pivotably connected to the backrest bracket (34) and a second end pivotably connected to the seat support bracket (30). The axis of rotation of the backrest (14) is located so as to pass approximately through the hips of a chair occupant. Further, the linkages are so selected and arranged that the reclining motion and return motion take place by a horizontal translation of the center of gravity of the occupant to minimize the effort required to operate the reclining mechanism through its range of movement.
