Abstract: The invention relates to a movement device for mounting in a support device and a support device which entails that at least one part of the device actively moves in a continuous, predetermined fashion. The pattern of the movement occurs independently of the movement of the user. The movements entail that the muscles of the user are continuously activated changing the muscle strain of the user, which entails that the user does not get tired and sore as quickly as usually. The invention further relates to a support device, such as a bed or a chair comprising such a movement device.

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.
