    • A chair having an articulating backrest that deforms when reclined to support an occupant's head or shoulders. A backrest assembly includes a mesh insert secured to a frame, which includes an upper frame section and a lower frame section interconnected by a pair of articulated joints. A push arm pivotally connects to the chair's seat assembly and to the backrest's upper frame section. As the chair reclines, the push arm restricts the angular movement of the upper frame section relative to a floor. The lower frame section moves forward relative to the upper frame section. Consequently, an angle formed between the lower frame section and the upper frame section decreases during recline, thereby supporting the chair occupant's head or shoulders. Optionally, a tensioning member may connect the mesh insert to the push arm to offset any loss of tension caused by the deformation of the frame during reclined.
    • 具有铰接靠背的椅子在倾斜以支撑乘员的头部或肩部时会变形。 背靠组件包括固定在框架上的网状插入件,其包括通过一对铰接接头相互连接的上框架部分和下框架部分。 推臂枢转地连接到椅子的座椅组件和靠背的上部框架部分。 随着椅子倾斜,推臂限制上部框架部分相对于地板的角运动。 下框架部分相对于上框架部分向前移动。 因此,在斜躺期间,下框架部分和上框架部分之间形成的角度减小,由此支撑椅子乘员的头部或肩部。 可选地,张紧构件可以将网状插入件连接到推臂以抵消在斜倚期间由框架变形引起的任何张力损失。
