  • Patent number: 10856665
    Abstract: The invention relates to seating furniture, in particular an armchair or sofa, with at least one backrest, at least one headrest, and at least one headrest adjustment. The headrest is held adjustable relative to the backrest by means of the headrest adjustment. The headrest adjustment has two height-adjustable positioning struts bearing the headrest and each is guided via a separate guide for adjusting the at least one headrest from the lower position into the upper position and back so that the headrests or the headrest adjustments are less prone to jamming or wedging, without disproportionate manufacturing costs. The guides each have a gear rack element and a gear wheel element meshing with the gear rack element when adjusting the headrest from the lower position to the upper position and back. The gear wheel elements are connected to one another in a torsion-resistant manner via a synchronous strut.
