Abstract: A progressively curved lumbar support located within the back of an office or home chair to enable a user to be seated close to a work surface (e.g., a desk or a table). The chair back tilts backwards and forwards when the user shifts his weight back and forth. The lumbar support includes a cushion back support manufactured from a resilient material that is responsive to a compressive force applied thereto when the user reclines against the chair back. In particular, a tilt pressure-responsive rod rides up and down over a pair of inclined guide blocks to cause the cushion back support to change its shape from a convex configuration at which to support the user's lower back and maintain a proper posture when the user sits erect and the chair back stands upright to a relatively flattened configuration when the chair back tilts backwards.
Abstract translation: 位于办公室或家庭椅子后部的逐渐弯曲的腰部支撑件，使得使用者能够靠近工作表面（例如桌子或桌子）坐下。 当用户来回转动时，椅子向后和向后倾斜。 腰部支撑件包括由弹性材料制成的靠背支撑件，该弹性材料响应于当使用者靠着椅子靠背时施加到其上的压缩力。 特别地，倾斜压力响应杆在一对倾斜的引导块上上下滑动，以使得靠背支撑件从凸起的构造改变其形状，在该构造下支撑使用者的后背，并且当用户保持正确的姿势时 直立时，椅子背靠背向后倾斜，直立到相对平坦的构型。

Abstract: An adjustable chair structure comprises a support frame of substantially L-shape conformation supported by a base in the form of an upright column supported on a set of radial feet carried on castors. The L-shape support frame has a horizontal arm for supporting a seat part of a seat body, and an upright (i.e. vertical or inclined at an acute angle to the vertical) arm which supports a seat back part of the seat body. The seat part is connected to the seat back part by means of a flexible tongue projecting from the middle of the rear edge of the seat part of the seat body, which tongue has notches by which the position of the seat back with respect to the seat part can be determined.

Abstract: The chair has a back rest provided with stiffening means which impart to the back rest a substantially stiff form up to about the level of the sixth lumbar vertebra of the chair occupant, thus ensuring a continuous transition from the chair seat to the back rest, but allow the back rest an increasingly greater flexibility from said level upwards with the result that the upper part of the back rest bends backwards when the occupant leans back, further characterized in that the upper end of the back rest is joined to the shoulder rest via a bracing corrugation in order to ensure that the chair profile in the region of the occupant's shoulder is a smooth curve matching that of the occupant's spine.
Abstract translation: 椅子有一个靠背，其上设有加强装置，该扶正装置将背部基本上硬的形式赋予椅子乘员的第六腰椎的水平，从而确保从椅子座椅到靠背的连续过渡，但是 允许靠背从所述水平向上越来越大的灵活性，结果是当乘客倾斜时，靠背的上部向后弯曲，其特征还在于，靠背的上端经由 支撑波纹，以确保乘员肩部区域的椅子轮廓与乘员的脊柱匹配的平滑曲线。
