Patent ID: 11291575

Abstract:
A headrest device includes a headrest (1) which is movably mounted on a back support (3) associated with a harness (4) for holding the back support on the back of a user. The headrest is mounted to elastically slide in longitudinal translation along the back support and is elastically attached to the back support in an articulated manner to tilt transversely. The headrest is used continuously according to the movements of the head in extension thereof towards a nominal resting position. The device may include a first torsion spring acting antagonistically in relation to the transverse tilting movements of the headrest and a compression spring acting antagonistically in relation to the longitudinal translation movements of the headrest. The two springs act synchronously during operation, continuously tracking movements of the head of the wearer in relation to a nominal rest position, with non-sliding support at the back of the head.
