Abstract
An adjustable support in the form of a headrest comprises a flexible arm (2) carrying a bifurcated branches (3a). The arm (82) is made up of identical segments (20) that can pivot in relation to each other. A wire (5) holds the arm (2) together and may be loosened by an adjusting mechanism (6) controlled by a knob (9). Partially cylindric surfaces (27, 29) on opposing ends (21, 22) of segments (20) have teeth-like projections extending transversely of the partially cylindric faces (27, 29) for mutual engagement and securing mutual position of adjacent segments (20). The adjustable support is thus able to carry greater loads than prior art adjustable supports.
Claims12
Adjustable support including an elongated structure consisting of segments engaging each other in succession, wherein each segment is provided with opposed pivot surfaces at respective ends thereof, facing away from each other for contacting and abutting on an adjacent segment, the two opposed pivot surfaces of each segment being provided with complementing convex and concave, respectively, curving shapes that are generally partially cylindric and provided with teeth-like projections, and wherein the support is held in fixed position by means of a wire extending through the segments in the elongated structure as the teeth-like projections on abutting segments engage each other, wherein the teeth-like projections extend in parallel with generatrices to the partially cylindric shape of the opposing pivot surfaces, and where each segment consists of two parts, a first part and a second part, where an adjustable interface is provided between said first and second parts.
