초록 ▼

An adjustable headrest includes a base supporting a crescent-shaped pad. The bottom side of the base is equipped with two triangular support structures, each of which includes a long arm and a short arm pivotally attached to distal and proximal junction structures, respectively, on the bottom side of the base. The other end of the arms are commonly and pivotally connected to a horizontal rod, one end of which is equipped with a cam lever capable of jointly controlling the lock and release status of two clamps, each of which is associated with one of the support structures. In each triangular support structure, one of the arms has an adjustable effective length. The cam lever is movable between a lock-position and a release-position. When the lever is in the lock position, the clamp prevents all rotational movement of both rectangular support structures about the horizontal rod, and prevents any adjustment of the effective length of the arms. The headrest support assembly allows height and angle adjustment of the headrest relative to a stationary table or chair by manipulating only a single clamp.

An adjustable headrest comprising: a base structure having an open central region, a top side and a bottom side, wherein an imaginary longitudinal plane perpendicularly bisects the base structure into two lateral portions; proximal and distal junction structures secured in a fixed orientation near and relative to the bottom side of the base structure; a short arm having a first end and a second end, the proximal junction structure being pivotally connected to the short arm near its first end; a long arm having a first end and a second end, the distal junction structure being pivotally connected to the long arm near its first end; a rod, perpendicularly oriented relative to the longitudinal plane forming a common axis of rotation for both the short and long arms near their second ends; said second triangular support structure is spaced apart and distinct from said first triangular support structure, wherein a first triangular support structure is defined, from a side view perspective, by the two arms and the portion of the base structure which extends between the two junction structures, each of the arms having an effective length relative to the triangular support structure, one arm\s effective length being adjustable by sliding movement in a direction perpendicular to the rod; a second triangular support structure in the same form as the first triangular support structure, said second triangular support structure is spaced apart and distinct from said first triangular support structure, wherein each lateral portion of the base structure has one of the triangular support structures attached to its bottom side; and a clamp associated with the rod, capable of alternately locking and releasing all pivotal orientation and effective length adjustment of the arms of both triangular support structures relative to the rod.
